Innovation

SPECIFICATIONS

For over 65 years, the name Titus has been synonymous with innovation in commercial air distribution. Many of the solutions we have developed over the years are still tried and true core products in our industry today. Intelligent Innovations speaks to our ability to solve problems and look at air distribution in new ways. Our true passion, however, lies in our ability to find clever and creative ways to enhance occupant comfort. Clever. Creative. Comfort. Several examples can be found within the pages of this catalog, and one of the stand-out products is the EOS; the industries first solar-powered, energyharvesting auto-changeover diffuser. Not only does the EOS provide THE solution for perimeter heating and cooling challenges, but it decreases the time it takes for an occupied zone to reach the setpoint, over the traditional split compromise diffuser, to improve occupant comfort. Additionally, the technology at work in the EOS provides us with a scalable energy

CORPORATE VALUES

harvesting platform to use as a jumping off point to address thermal comfort in revolutionary ways. Another cleaver and creative example innovation from Titus is the Plexicon. Displacement ventilation, while a great solution for cooling a space, usually requires a separate or supplementary system for heating; which affects the design, installation and overall cost of a project. The Plexicon addresses this challenge by incorporating displacement cooling and mixedairflow heating into a single diffuser assembly with auto-changeover action. Providing both cooling and heating from the same diffuser eliminates the need for a secondary heating system, reduces overall project costs, and delivers a high level of thermal comfort to the building occupants. At Titus, we are continually working on developing new ways to advance the science of air distribution.

Green Building design and energy conservation concepts are not new, yet in recent years the focus throughout the world has been to build structures with these principles in mind. We have seen the positive impact that designing and creating green buildings with these concepts have on our community and more importantly the world in which we live. As such, 100% of our focus for the past couple years and going forward has been on developing and delivering Green Solutions, and not just any Green Solution, but relevant Green Solutions. This is exactly the purpose of the Titus Energy Solutions website. The Energy Solutions micro-site is a first of its kind for any HVAC manufacturer in the industry. Our tagline, The Leader in Air Management is not just words. Titus is fully committed to provide the latest innovations to the HVAC market and this new website is just another piece to an ever-growing puzzle. By being singularly focused on Green products and Green Building CORPORATE VALUES

concepts, this website provides a portal into the latest developments in training, design, energy conservation, and news that directly affect us. We made every effort to incorporate all the tools needed to find the perfect Green Solution. Within the site you will find relevant product information, marketing collateral, LEED tools and other energy conservation related resources. We offer a wide array of Green products that can be used in a variety of applications. Whether you have a ceiling application or an underfloor installation, Titus has the Green Solution for you! Many of our products are GreenSpec Listed and we have a knowledgeable and experienced staff of industry professionals ready to provide assistance when needed. The marketing collateral we have made available on the Energy Solutions site is directly related to our Green products as well. The Energy Solutions

Brochure and the Retrofit Energy Solutions Guide are two brochures created to focus on Green products. The Energy Solutions Brochure is a 4-page guide that not only shows the types of products we offer, but highlights what LEED Credits they assist in achieving. The Retrofit Energy Solutions Guide provides a more thorough look into how an older building can be retrofitted and the energy savings available if new system or components were to be installed.

Our goal in creating the Energy Solutions website is to provide you with a very informative and green-focused interactive resource for today’s demanding building needs. Sustainable design and energy conservation concepts are here to stay and this new tool will assist you in meeting those demands.

We have also completely revamped our case studies to provide a more in-depth perspective into some of our Green projects. They illustrate the overall design process from concept to completion. Our case studies also display which Titus products were selected and highlights how they solved the project’s air distribution needs. We also have flyers, green presentations, installation manuals, and application guides available on the site.

The HVAC system plays a vital role in achieving healthy buildings to work in, but the LEED Credits associated with them tend to be missed. The sections of LEED that directly relate to Titus’ air distribution products primarily fall under Energy & Atmosphere (EA) and Indoor Environmental Quality (EQ) sections of LEED. The U.S. Green Building Council’s Leadership in Energy and Environmental Design standard (LEED) has quickly become the basis for determining a building’s “Green” status.

THE TITUS SOLUTION Titus supplied 1760 Vertical Stack fan coils for all the hotel rooms at the resort. Due to very specific requirements, a number of “special options” had to be incorporated into the standard Titus Vertical Stack fan coil to achieve a number of energy and installation cost savings. The primary special option and probably the most challenging to incorporate into a fan coil due to the high humidity in Orlando was the introduction and treatment of direct fresh air to the unit. This option not only provided substantial financial savings on the equipment and installation but also reduced the space required to layout the additional ductwork for a secondary fresh air system supplied by dedicated air handling units typically installed in the building roof. The solution to the challenge was the addition of a secondary “Wild Coil” in each unit with all the necessary controls which not only tempered the fresh air introduced directly from outside into each room but

also removed the excessive humidity particularly during the summer months. In coordination with Coastal Mechanical Services LL, Titus had to increase the spacing between the risers to allow the press tool to clamp the fittings into the riser pipes. Lastly and in order to achieve the highest energy cost savings, a specific thermostat was selected that cycled the fan/motor on and off at specific set points as specified by KLG/Orlando in order to meet the energy savings required by the resort owners.

THE END RESULT The Rosen Shingle Creek Resort Hotel is an example of a typical success story when all parties involved collaborate and work toward a common goal. It’s also an impressive structure that honors the location and history in which it was constructed while incorporating new building technology for the current generation of guests to experience.

UNF OSPREY FOUNTAINS RESIDENCE HALL CLIENT:

University of North Florida

REPRESENTATIVE OFFICE: Tom Barrow Company

ABOUT THE PROJECT The University of North Florida recently opened a spectalular dormitory for its ever-growing student body. At first glance, The Osprey Fountain residence hall is reminiscent of a luxury hotel that can be found on any tropical getaway. This LEED Silver Certified Building was designed by the Haskell Company and is 370,000 square-feet of space filled with many amentities for the students. The residence hall comes with laundry facilities, common lounges and kitchens, study areas, a convenience store, exercise and aerobics room, game room, swimming pool and lazy river pool, running and an 800 foot boardwalk through a natural wetlands.

THE TITUS SOLUTION The Osprey Fountains residence hall will be the largest on campus and required specially designed fan coil units to meet needs of the university and students. The Vertical High Output (VHC) fan coil unit was selected as the base design

for the project but needed several special features and modifications added in order to make the VHC unit the perfect choice for the Osprey Fountains. With Titus’s strong ability to customize fan coil units to meet a wide variety of project specific requirements, the VHC was customized to meet and exceed the University’s needs. Traditionally the VHC fan coil unit is installed in locations where the unit is not readably visible and is typically not painted. At the Osprey Fountains residence hall the units would be more visible and to make the units more aesthetically pleasing, the fan coil units would need have a painted finish provided. To accommodate the large size of the project, Titus found that it would be more cost effective to purchase 30,000 lbs. of pre-painted steel rather than paint the units individually. The VHC units used gray, pre-painted steel for the outer cabinet and any other components visible from the outside of the unit. Due to the location of the units and to improve filter maintenance, a rear access filter change out ability is also a requirement.

To accomplish this need, Titus designed a custom rear panel that would allow maintenance staff to remove this panel from the back of the unit and access the filter located in the front of the unit. To decrease unit installation time as well as to accommodate a variety of project site water connection locations, a method of connecting the fan coil unit to the building’s water supply would need to be provided. Stainless steel flex hoses were provided to make installation easier by allowing flexibility rather than rigid piping connections. In addition, Titus created an extra access cover that would be easily removable from the top of the unit and would enable maintenance staff greater access to service the valve package section of the fan coil.

THE END RESULT Titus is proud to provide Tom Barrow Co. and the University of North Florida with a customized fan coil product to make the Osprey Fountains Residence Hall a wonderful addition to the campus. This project underlines Titus’s ability to provide customized solutions to meet a wide variety of client needs. TITUS GREEN CASE STUDY

THE TITUS SOLUTION Over 380 Vertical Stack fan coils were installed in majority of the rooms at the new residence hall. While reviewing the specified unit, we noticed flaws that could be improved upon. It had a slanted coil and was basically a vertical stack unit sitting on 4 legs. The contractor intended to run flex connection ducting from the wall, go between the legs of the unit, and then turn it 90째 up and connect into the bottom of the unit. What we saw was an opportunity to improve the overall design, thereby saving the contractor time and money, while reducing the possibility of future maintenance costs.

vative solution that far exceeded their expections. Once the design of the unit was complete, we had given the engineers a complete redesign of our vertical stack unit to include every required feature at the most competitive price available.

THE END RESULT By working closely with our reps, contractors, and engineers on projects such as The University of Georgia, we are able to determine and meet their specific needs while building future relationships and innovative products.

After several discussions and brainstorming sessions with the engineers, we were able to achieve all of our intended objectives and provide them with an innoTITUS GREEN CASE STUDY

Heat Transfer

ASHRAE defines heat transfer as “the flow of heat energy induced by a temperature difference.”

Thermal convection is the transfer by eddy mixing and diffusion in addition to conduction.

Heat loss is measured in “Btu” which is the amount of heat required to raise 1 lb. of water 1BF. Coefficients used to estimate the value of the heat loss include: • K Factor, which is the amount of heat transferred in 1 hour through 1 sq. ft. of material, 1” thick at 1BF of temperature difference. • C Factor, which is the amount of heat transferred in 1 hour through 1 sq. ft. of material through the specified thickness of the material used. • R Value, is the resistance to heat transfer, measured as the reciprocal of conductance (1/K or 1/C). • U Value, designates the overall transmission of heat in 1 hour per sq. ft. of area for the difference of 1BF across specified material. • Conductance of individual materials is not directly applicable to the heat loss calculation. First, it must be converted to the ‘R’ value, which is (1/K or 1/C).

The transfer of fluid currents produced by external sources, such as by a blower, is called forced convection.

Equation 1: For a structure with multiple skin materials, the total heat transmission can be calculated as:

Thermal energy can be transferred or be affected by: • Conduction • Convection

• Radiation • Humidity

Thermal conduction is the mechanism of heat transfer by the transfer of kinetic energy between particles or groups of particles at the atomic level. With solid bodies, such as with an air jet near a window, thermal conduction dominates only very close to the solid surface.

When the fluid air movement is caused by the difference in density and the action of gravity, it is called natural convection. Natural convection is very active near windows and near heat sources in the occupied spaces. The colder air falls and the warmer air rises. Radiant heat transfer takes place through matter. It is a change in energy form, from internal energy at the source to electromagnetic energy for transmission, then back to internal energy at the receiver. Examples of radiation are sunshine through the air and window to the inside floor or ceiling light to occupants and to the floor. All of these methods of heat transfer effect a person’s comfort reaction. In addition, humidity has some effect caused by a change in evaporation rate from the body.

FAN COILS

Heat transfer is also affected by the following factors: • A greater temperature difference will result in a greater amount of heat transfer. • The amount of surface area is directly proportional to the amount of heat transfer. • The amount of time is also directly proportional to the amount of heat transfer. • The thermal resistance of the material use affects the rate of heat transfer.

U = 1/(R1 + R2 + …..Rn)

HYDRONIC (FAN COIL) SYSTEMS For hydronic heating and cooling fan coil systems heat is removed from the occupied space (cooling) or added to the occupied space (heating) via a closed looop water system. Return air from the space passes across a fin tube coil. The re-conditioned air is returned to the space through the supply air outlets. During the cooling season, heat from the return air is transferred to the water passing through the coil. The warmer water is piped to the chiller where the heat is removed and the cooler water is re-circulated. After the return air passes through the coil and the heat is removed, it is directed back to the space through the supply air outlets as directed by the room thermostat. During the heating season, the cool return air passes through the fin tube coil. Return air is heated by the warm water being piped through the coil, and is directed back to the room through the supply air outlets as directed by the room thermostat. Manufacturer’s performance data will quantify the coil heat transfer rate (Btu/H), given the airflow rate (cfm), entering air temperature dry and wet bulb (eat), water-flow rate (gpm) and entering supply water temperature (ewt) or entering and leaving water temperature (ewt/lwt) instead of water flow rate.

Room Load Calculations

Engineering Guidelines - Fan Coils

Some of the unique features differentiating fan coil applications from other commercial applications include: Heat gains are primarily imposed on the building through walls, windows, ceilings, doors and infiltration. Loads imposed by people and lighting is less significant. Load characteristics for fan coil zones can be more narrowly defined than zones for commercial spaces. The factors for a specific zone orientation, outdoor exposure and climate zone need to be considered. Exterior or interior shading and the time of the day affect the solar load. Another load on the space may be imposed by infiltration of outdoor air through windows and doors. Additional implements may be used for occupant comfort during extreme design situations. Ceiling fans can provide occupant comfort during warm conditions. Heat from sources such as a fireplace may provide extra comfort for cold conditions. For sleeping rooms, bed linens may be added or removed to enhance comfort. Most fan coil systems are used for relatively small capacity systems. Because loads are commonly determined by outdoor conditions, and very few days during a heating or cooling season are at design conditions, partial load conditions are prevalent. Therefore, over sizing the unit can decrease comfort in the space, especially during humid conditions. During high humidity operations with lower dry bulb temperatures, the thermostat will direct an oversized unit to short cycle, leaving uncomfortable levels of humidity in the space. For climate zones with higher humidity levels, selecting a smaller capacity unit will allow for maximum dehumidification and comfort for the majority of the cooling season with slight discomfort on the few days when design conditions occur. Additional information and a detailed discussion of calculating the cooling and heating loads in a space can be found in the Air Conditioning Contractors Association (ACCA) Manual N for Commercial Load Calculation, ASHRAE SDL Curriculum on Heating and Cooling Loads, or ASHRAE TC-4.0 Technical Committee for Load Calculations. The following are some equations commonly used for heating and cooling load calculations in a space.

Equation 2: Heat transfer through a window or wall: Q = U * A (t1 â&#x20AC;&#x201C; t2) Where : Q is the Btu/H U is the overall coefficient Btu/HA A is the area in Ft2 t1 and t2 are the temperatures in BF

Equation 3: Equation for exterior surfaces â&#x20AC;&#x201C; cooling: Q = U * A * Dt

Where: Q is the heat flow in Btu/H U is the value for the component under consideration Dt is the temperature difference across the component under consideration

Equation 4: Equation for heating and non-exterior cooling: Q = U * A * Dt Where: Q is the heat flow in Btu/H U is the value for the component under consideration Dt is the temperature difference in degrees F between indoors and outdoors across the component under consideration, taking into account the combined effect of radiation, time lag, storage and temperature

For fan coil products the typical application characteristics are similar to multi-family residential building. For these structures heating and cooling load calculations will differ from commercial applications.

Psychrometrics

One of the four major elements of thermal energy and comfort is humidity. Psychrometrics uses thermodynamics properties to analyze conditions and processes involving moist air. A detailed study of psychrometrics can be found in Chapter 1 of ASHRAE 2009 Fundamentals Handbook. This section is a summary of how knowledge of psychrometrics can be used to maximize space comfort and system performance.

The Wet-bulb Temperature (WBT), is the temperature measured using a ‘wetted’ thermometer. Wet-bulb is used to determine the moisture content of air. The Absolute Humidity (AH), is the vapor content of air. It is described in terms of moisture per lb of dry air or grains of moisture per lb of dry air. AH is also referred to as ‘moisture content’ or ‘humidity ratio.’ There are 7000 grains in a lb. of water.

The Relative Humidity (RH), is the vapor content of air. It is described as the percentage of saturation humidity at the same temperature (%). The goal for optimum space comfort is 30-35% for heating conditions, and 45-60% for cooling conditions. Saturation humidity is the maximum vapor content (lb/lb) per lb dry air that air can hold at a fixed temperature.

A psychrometric chart (Figure 115) is a graphical representation of the thermodynamic properties of moist air. There are several charts available to cover all common conditions. The one shown here is taken from ASHRAE 2009 Fundamentals Handbook, Chapter 1 and illustrates conditions of 32 to 100BF at sea level.

The Dew Point Temperature (DPT), is the temperature at which vapor begins to fall out of air to form condensation. DPT is the temperature at which a state of saturation humidity occurs, or 100% RH. It is also known as the saturation temperature.

The Dry-bulb Temperature (DBT), is the temperature measured using a standard thermometer. Dry-bulb is also known as the sensible temperature. 55

Engineering Guidelines - Fan Coils

The Enthalpy (H) is the heat content of air. Enthalpy is also known as the total heat of air. Enthalpy is dependant on the wet-bulb temperature of air. It is described in terms of Btu’s per lb dry air (Btu/lb). A Status Point is a location on the psychometric chart defined by any two psychometric properties. A hydrometer or psychrometer is commonly used to define a status point. Using a psychrometer. A sling psychrometer incorporates a standard thermometer and a wetted thermometer. The wetted thermometer should be dipped in room temperature distilled water. The psychrometer is spun (slung) until the wet-bulb temperature has stabilized.

Sensible heating (Qsen), is the heat that raises the dry-bulb temperature of air without increasing the moisture content. Because we can easily sense this change in temperature, it is called ‘sensible.’ Sensible cooling is the removal of heat without removing moisture content of the air. Latent Heat (Qlat), is the heat content of air due to the presence of water vapor. Latent heat is the heat required to evaporate this same amount of water (970 Btu/lb), also known as the latent heat of vaporization. As latent heat increases, moisture content increases. Water can be heated to 212BF. If more heat is added, the water will vaporize but the temperature will not change. Latent Cooling (Qlat), is the removal of latent heat from air without lowering the dry-bulb temperature. To retrieve 1 lb. of condensate, 970 Btu’s would need to be removed. As latent heat decreased, moisture content decreases. Latent Heat of Fusion is the heat required to change a liquid into a solid (144 Btu/lb. Water can be cooled to 32BF. If more heat is removed, it wall cause ice to form. To retrieve 1 lb of water from ice, 144 Btu’s will need to be added.

When the wet-bulb temperature has stabilized, record both the dry-bulb and wet-bulb temperatures on your log sheet. Because of evaporation, the wet-bulb temperature will be equal to or less than the dry-bulb temperature.

At 100% RH the wet-bulb will equal the dry-bulb temperature. (Locate an umbrella before continuing the test). As the temperature difference between temperatures increases, the RH will decrease.

Sensible heat factor is the measure of sensible heat to latent heat. Sensible heating only is 1.0. Equal proportions result in 0.5. SHF is generally higher than 0.5 because of the cooling processes that remove more sensible heat than latent heat. For residential applications the typical Sensible heat factor is 0.8.

To locate your status-point, find the dry-bulb temperature on the bottom of the psychometric chart. Follow this line upward until it intersects with the wet-bulb temperature from the left side of the chart.

www.titus-hvac.com | www.titus-energysolutions.com

The Specific Volume (Spv), is the reciprocal of air density which is described in terms of cubic feet per lb of dry air (cu ft/lb). An increase in air temperature will result in a decrease in density and an increase in volume. A decrease in atmospheric pressure also decreased air density while increasing volume. At 5000 feet above sea level, density is decreased by 17%. Higher altitudes require larger motors and blowers to move the same effective mass, due to the increase in specific volume.

From the ‘status point’ you can locate:

• Absolute Humidity (AH) • Relative Humidity (RH) • Dew Point Temperature (DPT) • Specific Volume (Spv)

If the surface temperature is equal or lower than the DPT, the surface will form condensation. If yes, an additional thermal barrier may be required to solve the problem.

Next, determine the DPT of the atmospheric air in contact with the surface.

Properties of Coils and Coil Design

Engineering Guidelines - Fan Coils

Fan coil units are typically selected and sized to heat and cool a small zone with specific load requirements. Each unit defines a small zone, which typically serves a few rooms with a centrally located thermostat. Basic and vertical stack units are usually selected for single room applications. The hot and cold water supply usually serves all or part of a single building. Water can be supplied to each unit through a two-pipe or four-pipe water supply system.

Air Stream

T = 80°F

T = 60°F

Two-pipe systems will have a lower installed cost. With a two-pipe system, both hot and cold water are supplied using the same pair of pipes. The lower cost usually translates to a lower level of occupant comfort. This limitation can cause problems when heating is desired in one unit at the same time cooling is desired in another due to solar or internal load requirements. For moderate climate regions, two-pipe systems can operate in the cooling mode with supplemental resistance heat available in zones requiring heat. Four-pipe systems maintain higher levels of occupant comfort for all seasons. Both hot and cold water are left operational during the spring and fall seasons. This additional comfort may result in higher operational cost for utilities to operate both the chiller and the boiler during the spring and fall months.

Water side applications for fan coil designs use a chiller to lower the water temperature for heat removal and a boiler to raise the water temperature to overcome heat losses. The water supply used is typically supplied by the local utilities. Other chemicals may need to be added to the water. Sometimes, local climate conditions require that additives such as Ethylene glycol, Propylene glycol, Methanol, Calcium chloride or Sodium chloride be added to the water supply. Care should be taken to account for changes in heat transfer caused by these additives.

Vertical Stack Risers

Engineering Guidelines - Fan Coils VSR VSM

Vertical stack models can minimize installation cost because the units are orientated one on top of the other and use common supply and return water pipes. For tall structures with more than three floors, it is recommended to adjust the pipe size for optimum performance. The term “riser” describes the pipe used to transport supply or return water (chilled or hot) to or from the vertical stack unit water coil as well as condensate water from the drain pan.

VSR VSM

Risers are typically insulated with elastomeric, closed cell, thermal insulation to minimize heat loss or gain from the water to the ambient space. If the unit is not equipped with a riser pipe of adequate length to reach from floor to floor, a riser extension can be installed to connect the vertical stack unit to a unit located on an adjacent floor. The riser extension can also act as the transition where the pipe size changes from one floor to the next. The diameter of the pipe will increase or decrease as piping extends throughout the building in order to equalize pressure and velocity of the water flow.

VSR VSM

www.titus-hvac.com | www.titus-energysolutions.com

For high-rise buildings where a common floor to floor footprint is present, it may be economical to design the system using vertical stack fan coil units.

RISER SIZING A detailed discussion on water pipe sizing can be found in the ASHRAE 2009 Fundamentals Handbook, Chapter 22. In general, operating pressure between the supply and return riser is in the range of 10 to 15 psi. Design velocities are typically between 1 and 4 fps. Typical riser pressure loss is designed for about 3 feet of head pressure loss per 100 feet of piping. As a rule of thumb, 10 feet of head pressure equates to about 5 psi.

Controls and Valve Packages

The room thermostat performs the function monitoring the room temperature conditions and signaling the unit fan and valve controls to operate within in preset limits to maintain occupant comfort. Figure 125 shows a basic two-pipe system package. Supply water is piped to the bottom of the coil to ensure that any air bubbles forming in the supply water will be transmitted to the upper level where they can be discharged from the system through the optional air vent on the return pipe immediately outside the coil. Shut off valves are located on both supply and return waterlines to enable the coil to be isolated during installation and maintenance.

Drain valves allow the coil to be drained during maintenance or removal.

Unions can be provided for the connection of the water coil to the supply and return water lines. Unions allow the water coil to be removed from the unit without cutting into the water lines and soldering them together during installation and maintenance.

A two-way water valve is used to adjust and balance the water flow into the coil to provide the specified amount of heat to the zone.

Pete’s Plugs provide the installer or maintenance technician a tool for connecting a pressure gage for reading the water pressure at the coil.

A valve motor operates on a signal from the room thermostat to adjust the water flow in response to space heating conditions.

Flow Control Valves are available as fixed or adjustable options. A fixed valve will be sized in accordance to the CV specified by the design engineer to provide the water flow required to meet the maximum load conditions required in the zone. This feature may save time during the initial start up. An adjustable valve must be commissioned at the jobsite during start up to limit the specified water flow to the coil. The adjustable feature does provide for future changes to match changes in load requirements.

The air vent allows air bubbles to escape the system for maximum heat transfer system performance. Optional control components, (Figure 126), are available to enhance the operations of the system or improve the process of installation and maintenance.

A Motorized Water Valve can be provided. The motor will be operated in response to a signal from the zone thermostat to automatically reset the water flow to meet changing zone load requirements. A two-way valve controls water flow by opening or closing the flow control valve to the coil with a spring return. A three-way valve controls flow to the coil by bypassing excess water directly to the return pipe. The Y-Strainer option is installed in the supply water line ahead of the coil. It will remove sediment from the water supply before it can enter the coil and restrict water flow and reduce system performance. Manual Shut Off Valves are available with or without memory stops. The basic valve allows maintenance personal to shut off the flow of water to the coil at the unit. The optional memory stop lets the operator re-open the valve to it previous position without re-balancing. An Aquastat Switch can be installed in the water supply line and connected to the thermostat. Aquastats are most commonly used where there is a two-pipe system or supplemental electric heat. The Aquastat senses when the supply water is for heating or cooling. For a two-pipe system, if a zone thermostat is calling for heat and the supply water is cold, the thermostat will be locked out. For supplemental heat, the heat will be locked out when warm water is available in the supply lines.

THERMOSTAT The zone thermostat may be mounted on the fan coil unit, on the wall near the unit, or mounted on the wall or in the return duct away from the unit. Thermostats may be powered by a 24-volt power supply (with transformer) or by the same line voltage as the unit. Economically, if the thermostat is physically located more than 8 feet from the unit, line voltage is preferred. Each fan coil controls the room space temperature in response to a signal from the thermostat. The thermostat is programmed with cooling and heating set-point values as directed by the occupant or building manager. Typically, the zone thermostat provides a read out to tell the occupant what the set-point temperature is for the unit and what the temperature is the temperature in the space at present. Space temperature control is + or -1BF from the set point temperature. (Thermostats with an auto-changeover feature have a 4BF dead-band for switching.) Other thermostat features include a three-speed switch for the occupant to adjust the fan output volume, a manual changeover switch to change operation from cooling to heating conditions and an on/off switch to override the thermostat and shut the unit off as desired by the occupant.

TERMINAL UNITS AHRI 220-2007 “Reverberation Room Qualification and Testing Procedures for Determining Sound Power of HVAC Equipment” This standard provides the methodology for the determination of sound power levels of noise sources that emit broadband sound and/or discrete frequency sounds/Tones in reverberation rooms.

AHRI 880-2011 “Performance Rating of Air Terminals” The purpose of this standard is to establish for air terminals: definitions; classifications; test requirements; rating requirements; minimum data requirements for published ratings; marking and nameplate data and conformance conditions. This standard applies to air control devices used in air distribution systems.

This standard provides a consistent industry-accepted method for estimating sound pressure levels in a conditioned space for the application of air terminals and air outlets. Air terminals, air outlets, and the low pressure ductwork which connects them are considered sound sources and are the subjects of this standard. The method described in this standard can be used to identify acoustically critical paths in the system design. The design effects of inserting alternative components and changes in the system can be evaluated.

This standard applies to all reference sound sources (RSS’s) used in conjunction with AHRI sound rating standards and covers the one-third octave band frequency range from 50 to 10,000 Hz.

The standard is classified as an ASHRAE standard method of measurement. This revision of the standard includes updates and revisions to all parts of the standard, including its title, purpose, and scope. It updates definitions, adds modulating diffusers, redefines airflow sensor performance testing, and adds a method to determine the power factor.

AHRI STANDARDS AHRI Standards are typically developed for rating purposes. When an appropriate method of test does not exist, then AHRI Standardwill develop one. Otherwise, by agreement, they will reference an ASHRAE Standard method of test. AHRI STANDARD 880 The purpose of this standard is to establish definitions and classification: requirements for testing and rating; specifications, literature and advertising requirements; and conformance for air terminals. Appendix A is the method of test, which is expected to be replaced by ASHRAE Standard 130. AHRI STANDARD 885 This standard gives sound transmission losses through ceilings, effects of plenum, loss through ducts and all consideration of the sound paths to the space. With many items that affect the final sound, it gives a procedure to estimate what the space sound levels will be. AHRI Standard 885 “Procedure for Estimating Occupied Space Sound Levels in the Application of Air Terminals and Air Outlets” This standard gives sound transmission losses through ceilings, effects of plenum, loss through ducts and all consideration of the sound paths to the pace. With many items that affect the final sound, it gives a procedure to estimate what the space sound levels will be. This standard is unique among acoustical standards in that it provides the most current available acoustical application data for boxes and diffusers. Most of the data comes form ASHRAE sources, but some parts are unique to this standard, including a flexible duct attenuation table and a combined ceiling/plenum attenuation table. Unique and important AHRI Standard885 elements are listed in the Paths section of this manual.

ASHRAE has developed, or is developing, consensus standards for testing both boxes and air outlets and inlets (GRDs). ASHRAE strives to provide current relevant testing standards which represent the best known data and methods available as consensus standards. ASHRAE Standards are submitted to American National Standards Institute (ANSI) and are usually adopted as ANSI standards as well. When applicable ANSI standards are available for part of ASHRAE Standards for both Boxes (130) and diffusers (70). ASHRAE 62 “Ventilation of Acceptable Indoor Air Quality.” The purpose of this standard is ‘to specify minimum ventilation rates and indoor air quality that will be acceptable to human occupants and are intended to avoid adverse health effects.’ This standard also specifies that energy conservation should be promoted and that comfort conditions should be maintained. Therefore the next two standards are listed to implement these requirements.

Breakout - Sound which passes through the walls of a duct or device and is passed directly to an observer. Casing Radiated Sound - A type of Breakout Sound which passes through the walls of a device. In some cases, it includes induction port radiated sound as well. dBA - A single number rating of a broadband spectrum. Typically used to rate outdoor noise levels. Not practical for use in rating indoor sound levels as it bears little relevance to occupants’ needs.

Sound Pressure - The directly measurable fluctuation in pressure, heard as sound. The sound pressure is reported in dB (the log base 10 of the value), referenced to a pressure 0.0001 microbars. It is reported by frequency, typically in octave bands, although sometimes in 1/3 octave bands.

Discharge Sound - Airborne sound which is transmitted through ductwork from a noise source to an observer.

Space Effect - The calculated attenuation of a space which is different in each frequency band, and is a function of room volume and distance from the source.

End Reflection - The reduction in sound, typically in low frequencies only, resulting from a rapid change in the shape or size of a duct or a duct termination. Environmental Adjustment Factor (Environmental Effect) - A correction required to accurately use data obtained in accordance with AHRI Standard 880 (or the proposed ASHRAE 130), it corrects for a calibration difference between the Free Field calibration of the Reference Sound Source and the reverberant field in which it is used. GRD - Grilles, Registers and Diffusers. A grille is typically a device which directs air out of a duct nearly the same size as the opening. A register is a grille with a damper. A diffuser is usually different in size than the supply duct, and usually changes the direction of the air while mixing it with room air. These definitions are not always used as indicated. Incoherent Sound - Sound which is broadband and contains no repeating fluctuations. Induction Port Radiated Sound - That sound which passes out from the induction port of a VAV device. In practice it is impossible to differentiate from Casing Radiated sound, and is reported as a combined value under Casing Radiated sound levels. Insertion Loss - The reduction in sound resulting from inserting an attenuation device, such as a section of lined duct. The difference before and after the insertion of such a device is the insertion loss.

GLOSSARY

Multiple Outlet Effect - When an airstream is split, the sound traveling in the duct is also reduced, typically in proportion to the percent of airflow in each duct. The amount of reduction must be calculated logarithmically, not arithmetically, however.

device. It is measured indirectly by one of several methods. It is reported as dB (the log base 10 of the value) referenced to a base power level, typically 10-12 watts. It is reported by frequency, typically in octave bands, although sometimes in 1/3 octave bands.

Pure Tone - A sound spectrum which is very concentrated in a narrow band. Radiated Sound - Sound which travels from the source to the observer in a direct path, outside ductwork. Room Effect - Typically a 10 dB reduction in all bands, this is the assumed value for attenuation of a room. In practice, it is reasonable for diffusers which peak in the mid-frequencies, but not necessarily for VAV terminals, which peak in lower frequencies. Sound Power - The energy released as acoustic energy by a

Terminals (Boxes) - Devices which vary the flow through a duct with a moveable damper. They typically have a control device to vary the flow in response to a control signal. In some cases, the term terminals can also mean boxes and GRDs. In those cases, “Boxes” are referred to as Air Control Devices (ACDs). The terminology is inconsistent throughout the industry.

Overview

The chilled ceiling products provide sensible cooling and heating to the space by utilizing the more efficient heat transfer capacity of water, as opposed to air. This decouples the latent and sensible loads, reducing the energy cost of sensible cooling. With passive beams and radiant products, an additional system is necessary to meet the ventilation and latent cooling needs of the space. The Titus active chilled beams integrate the supply of ventilation air creating an active diffuser. Using the ventilation air to pressurize a plenum with aerodynamically designed nozzles, high velocity jets of air are created forcing induction of room air over the water coils integral to the units. Forced induction dramatically improves the heating and cooling capacity over passive beams and radiant products. Titus active chilled

beams harness the energy of the supply air to further reduce total energy consumption. Titus offers a chilled ceiling product to meet the requirements of any design or installation. Just a single model of passive beam accommodates both exposed and recessed mounting applications. Active chilled beams are available in 1, 2, and 4-way throw patterns. There is even a model for high sidewall applications. In addition to the variety of product solutions available, the appearance of the units can be customized through standard options, which enables seamless integration into any architectural style, traditional or contemporary.

The Titus chilled ceiling product line is comprised of chilled beams, both active and passive, radiant ceiling panels, and radiant sails. These products offer optimized performance and provide high levels of thermal comfort for the occupant. In addition to increased occupancy comfort, use of the chilled ceiling products reduce the amount of energy required to heat and cool a building.

APPLICATION GUIDE

Introduction Chilled ceiling systems consist of three main product types: active chilled beams, passive chilled beams, and radiant ceiling panels/sails. Even though these units are commonly referred to as “chilled” products they are also effectively used for both cooling and heating. Both active and passive beams utilize water coils to provide sensible cooling, reducing the total load that must be addressed through the building’s air handlers. Since chilled beams provide sensible only cooling they are best suited for spaces with low to moderate latent loads. This offers considerable potential for energy savings due to the volumetric heat transfer capacity of water and trade-off between fan energy and pumping power.

Radiant ceilings systems emit heating and cooling by both convection and radiation. During cooling, ambient air near the ceiling cools and falls to the occupied area, due to its higher density. The ceiling panels emit cooling and heating to the surrounding surfaces in the area by radiation. Radiant heat transfer typically results in high thermal comfort since the ambient temperature will feel 2.5BF to 5BF cooler/ warmer than actual room temperature. This effect has the advantage that the room requires less conditioning than a traditional system, introducing an additional opportunity for energy savings.

Passive beams consist of a water coil and an enclosure. The enclosure is primarily cosmetic, but helps to maintain even heat transfer across the coil. Passive beams provide cooling primarily through convective heat transfer. A convection current is created where higher density cool air sinks into the space, inducing warm low density air at the ceiling level through the coil. When using passive beams ventilation air must be introduced to the space either through natural or mechanical means.

History

APPLICATION GUIDE

Modern chilled ceiling systems, more specifically active chilled beams, got their start in the 1920s when Willis Carrier began to develop the concepts for under-sill induction units. Patents were applied for and first installations of these units were completed in 1940. The use of an air-water terminal located in the space was an important advance in and of itself; however, these systems solidified the advantages of an air-water system over an all-air system.

Incorporating supply air into a beam creates an active diffuser. Ventilation air pressurizes a plenum and the aerodynamically designed jets induce room air over water coils. Forced induction dramatically increases the heating and cooling capacity per square foot, compared to passive beams and radiant products. Active chilled beams harness the energy of the supply air to further reduce total energy consumption.

• Water is much more efficient heat transfer medium than air. • Reduced duct size required to only supply ventilation air increased usable space, and reduced the material cost and installation time. Scandinavian engineers, during the mid-1970’s, adapted this technology along with radiant heating/cooling panels for overhead applications to work with new buildings designed to utilize natural ventilation. The result of their efforts was the passive chilled beam. In regions where using natural ventilation was not effective, engineers integrated the mechanical ventilation into chilled beam. Utilizing the same principles used in the under-sill induction boxes, the active chilled beam was developed.

APPLICATION GUIDE

HEAT TRANSFER

ASHRAE defines heat transfer as “the flow of heat energy induced by a temperature difference.” Thermal energy can be transferred or be affected by: • Conduction • Convection • Radiation • Humidity Thermal conduction is the mechanism of heat transfer by the transfer of kinetic energy between particles or groups of particles at the atomic level. With solid bodies, such as with an air jet near a window, thermal conduction dominates only very close to the solid surface. Thermal convection is the transfer by eddy mixing and diffusion in addition to conduction. The transfer of fluid currents produced by external sources, such as by a blower, is called forced convection. When the fluid air movement is caused by the difference in density and the action of gravity, it is called natural convection. Natural convection is very active near windows and near heat sources in the occupied spaces. The colder air falls and the warmer air rises. Radiant heat transfer takes place through matter. It is a change in energy form, from internal energy at the source to electromagnetic energy for transmission, then back to internal energy at the receiver. Examples of radiation are sunshine through the air and window to the inside floor or ceiling light to occupants and to the floor. All of these methods of heat transfer effect a person’s comfort reaction. In addition, humidity has some effect caused by a change in evaporation rate from the body.

Heat loss is measured in “BTU” which is the amount of heat required to raise 1 lb. of water 1BF. Coefficients used to estimate the value of the heat loss include: • ‘K’ Factor: amount of heat transferred in 1 hour through 1 sq. ft. of material, 1” thick at 1BF of temperature difference.

Equation 1: For a structure with multiple skin materials, the total heat transmission can be calculated as: U = 1/(R1 + R2 + …..Rn) For hydronic heating and cooling systems heat is removed from the occupied space (cooling) or added to the occupied space (heating) via a closed loop water system. Return air from the space passes across a fin tube coil.

PSYCHROMETRICS

Atmospheric Air (the air that you breathe), contains many gaseous components including water vapor and containments. Dry Air is atmospheric air with all moisture removed and is used only as a point of reference. Moist Air is a combination of dry air and water vapor and can be considered equal to atmospheric air for this discussion. A psychrometric chart (FIGURE 4) is a graphical representation of the thermodynamic properties of moist air. There are several charts available to cover all common conditions. The one shown here is taken from ASHRAE Fundamentals Handbook, Chapter 1 and illustrates conditions of 32 to 100BF at sea level. The Dry-bulb Temperature (DBT), is the temperature measured using a standard thermometer. Dry-bulb is also known as the sensible temperature. The Wet-bulb Temperature (WBT), is the temperature measured using a ‘wetted’ thermometer. Wet-bulb is used to determine the moisture content of air. The Absolute Humidity (AH), is the vapor content of air. It is described in terms of moisture per lb of dry air or grains of moisture per lb. of dry air. AH is also referred to as ‘moisture content’ or ‘humidity ratio.’ There are 7000 grains in a lb. of water. The Relative Humidity (RH), is the vapor content of air. It is described as the percentage of saturation humidity at the

APPLICATION GUIGE

• ‘C’ Factor: amount of heat transferred in 1 hour through 1 sq. ft. of material through the specified thickness of the material used. • ‘R’ Value: resistance to heat transfer, measured as the reciprocal of conductance (1/K or 1/C). • ‘U’ Value: designates the overall transmission of heat in 1 hour per sq. ft. of area for the difference of 1BF across specified material. • Conductance of individual materials is not directly applicable to the heat loss calculation. First, it must be converted to the ‘R’ value, which is (1/K or 1/C).

increase in specific volume. The Enthalpy (H) is the heat content of air. Enthalpy is also known as the total heat of air. Enthalpy is defendant on the wet-bulb temperature of air. It is described in terms of Btu’s per lb. dry air (Btu/lb.).

A Status Point is a location on the psychrometric chart defined by any two psychrometric properties. A hydrometer or psychrometer is commonly used to define a status point. At 100% RH the wet-bulb will equal the dry-bulb temperature. As the temperature difference between temperatures increases, the RH will decrease.

The Specific Volume (Spv), is the reciprocal of air density which is described in terms of cubic feet per lb of dry air (cu ft/lb.). An increase in air temperature will result in a decrease in density and an increase in volume. A decrease in atmospheric pressure also decreased air density while increasing volume. At 5000 feet above sea level, density is decreased by 17%. Higher altitudes require larger motors and blowers to move the same effective mass, due to the

To locate a status-point, find the dry-bulb temperature on the bottom of the psychrometric chart. Follow this line upward until it intersects with the wet-bulb temperature from the left side of the chart.

When will condensation occur? To determine if a supply air duct or air outlet device will form condensation on the surface: First, using the R-value of any thermal barrier, determine the minimum surface temperature. Next, determine the DPT of the atmospheric air in contact with the surface. If the surface temperature is equal or lower than the DPT, the surface will form condensation. If yes, an additional thermal barrier or other condensation prevention strategies may be required to solve the problem. Sensible heating (Qsen), is the heat that raises the dry-bulb temperature of air without increasing the moisture content. Because we can easily sense this change in temperature, it is called ‘sensible.’ Sensible cooling is the removal of heat without removing moisture content of the air. Latent Heat (Qlat), is the heat content of air due to the presence of water vapor. Latent heat is the heat required to evaporate this same amount of water (970 Btu/lb), also known as the latent heat of vaporization. As latent heat increases, moisture content increases. Water can be heated to 212BF. If more heat is added, the water will vaporize but the temperature will not change. Latent Cooling (Qlat), is the removal of latent eat from air without lowering the dry-bulb temperature. To retrieve 1 lb. of condensate, 970 Btu’s would need to be removed. As latent heat decreased, moisture content decreases.\

Sensible processes can be shown as horizontal paths on a psychrometric chart. Latent processes can be shown as vertical paths on a psychrometric chart. Most processes include both, resulting in an angled or diagonal path. Sensible heat factor (SHF) is the measure of sensible heat to latent heat. Sensible heating only is 1.0. Equal proportions result in 0.5. SHF is generally higher than 0.5 because of the cooling processes that remove more sensible heat than latent heat.

INDUCTION

Induction is a flow that occurs as a result of the change in velocity pressure as a jet of air expands. The principals of induced air flow are based on the Venturi effect. The

Benefits of Chilled Ceiling Systems Chilled Ceiling Systems are designed to provide superior occupancy comfort. These systems require less energy to operate, operate more efficiently, and use less materials than conventional all air systems. Tempered and dehumidified air is supplied to the space to meet ventilation requirements and to handle the latent load. The majority of the sensible load is addressed with the chilled ceiling products. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced volume of air that must be delivered to the space results in reduced air handler capacity and size, smaller duct sizes, and overall energy savings. A higher supply temperature contributes to increased occupancy comfort.

FIRST COST BENEFITS:

• Shallow unit profiles allow for reduced ceiling space requirements; typically require 60% less vertical space than conventional all air systems. "" Reduced slab to slab spacing; reducing material costs per floor. "" Easily integrated into retrofit applications where space is limited. • Low volume of supply air required for active beams enables reduction of the total amount of air processed at the air-handler by an all air system up to 50%. "" Reduced air-handler size/ capacity, and duct work size

COMFORT AND IAQ BENEFITS:

• Active beams typically supply a constant volume of primary air, decreasing occurrences of dumping and changes to the air motion in the space; issues common to typical VAV systems. • When supplied with primary air from a dedicated outside air system (DOAS) 100% fresh air is supplied to the space. • Dry-coil sensible cooling, eliminates bacterial, fungal, or mold growth associated with fan coils and other unitary products with condensing coils. • Constant primary air volume ensures ventilation requirements are met and helps to maintain relative humidity levels in the space.

APPLICATION GUIGE

Latent Heat of Fusion is the heat required to change a liquid into a solid (144 Btu/lb. Water can be cooled to 32BF. If more heat is removed, it will cause ice to form. To retrieve 1 lb of water from ice, 144 Btu’s must be added.

Venturi effect is a derivation of Bernoulli’s principle and the continuity laws. In order to satisfy the fluid dynamic principles of continuity, a fluid’s velocity must decrease as the flow expands; at the same time the static pressure of the flow must increase. The increase in static pressure balances the decreased velocity, thus maintaining the principles of conservation.

Chilled Ceiling System Design CHILLED CEILING APPLICATIONS

APPLICATION GUIDE

Chilled beam and radiant ceiling products are designed to handle high thermal loads in the space. They are also an effective solution in spaces where individual temperature control is desired. Ideal applications are spaces where the sensible heat ratio is greater than 0.75, meaning that 75% or more of the total heat gains in the space are sensible gains. These locations include computer/server rooms, condos/apartments/hotel guest rooms, libraries, and museums.

U10

Use of chilled ceiling systems should be limited to applications where cooling loads are less than 40 BTUH/ ft2, and heating loads are lower than 15 BTUH/ft2. More specifically, passive beam and radiant panel usage should be limited to applications where cooling loads are no more than 25 BTUH/ft2, and active chilled beams are not recommended for use when cooling loads are more than 40 BTUH/ft2. Chilled ceiling systems are not recommended in these applications since addressing the loads will likely create thermal comfort issues. In transitional spaces where thermal comfort is not critical, chilled ceiling products can be used to address higher loads. Chilled beams and radiant ceiling systems should not be applied in buildings where relative humidity of the space is not easily maintained. This would include retrofit applications, lobbies, and entrances where there is excessive infiltration. Chilled beams are best applied when installed no higher than 14 feet above the floor, but can remain effective with installation heights up to 20 feet. When installed above these heights it is difficult to effectively get heating and cooling into the occupied space.

PRACTICAL DESIGN GUIDELINES

There are guidelines that should be followed when considering a chilled ceiling system to ensure the design will create a comfortable environment for occupants and result in optimum energy efficiency. The system should be designed to meet only the heating and cooling requirements of the actual space. Overdesigning the system will increase the cost of the project, and potentially result in decreased comfort. Primary air must be adequately dehumidified, and supplied at a flow rate large enough to offset the latent loads of the space. This flow rate must also be high enough to meet the ventilation requirements outlined in ASHRAE standard 62.1. When heating with chilled beams and radiant panels, care must be taken that the system is not oversized for heating. Entering water temperatures should be as low as possible to meet the heating requirements, and should never be over 140BF. Condensation control strategies must be implemented to maintain optimum operating conditions, prevent bacterial, mold, and fungus growth, ensure damage to building does not occur. When designing a chilled beam system it is best to limit the types and configurations of products used. This will help to make logistics during installation and building maintenance easier. Room air temperature is maintained through regulation of 2-way control valves. Use of 2-way valves is preferred as they will minimize pumping costs. Systems should be designed to take full advantage of free cooling and heating opportunities through economizers and heat recovery devices. Chilled beams and radiant panels are highly efficient products and offer energy savings over traditional systems. However, one of the biggest advantages these products offer is the additional energy savings that can be achieved in the rest of the system due to the unit operating conditions.

DESIGN METHODOLOGY

The design of chilled ceiling systems is an iterative process between selection of the equipment to be used and the inlet conditions for the system. This also includes placement/ orientation. The iterative process enables the inlet conditions to be optimized so that the design results in a comfortable space for the occupant, and that the equipment is operating with the highest efficiency possible. This is true for all chilled ceiling systems, but is especially true for active chilled beams. Equipment selection is based on the following items and must be balanced for creating an effective, efficient, and comfortable system:

After control of the critical points has been established, additional controls to compensate for changes in space dew point temperature and occupancy should be considered through a building management system. This methodology is depicted in Figure 5, Chilled Ceiling Design Methodology.

System Design Process U12

SPACE DESIGN CONDITIONS

The first step in determining the space design conditions is to define the design temperatures for both heating and

cooling. This should be done by following the guidelines set in ASHRAE Standard 55 and the chapters on heating and cooling loads in the ASHRAE Fundamentals Handbook. Once the design temperatures have been defined, an iterative process should be used to determine the indoor air quality requirements, calculating the required capacities to address the heating/cooling loads, and adjusting the building design/construction (if applicable). The indoor air quality (IAQ) requirements include supply air flow rate, to meet both ventilation requirements and address the latent loads in the space, determining infiltration, and defining the maximum allowable humidity level. Based on the building design and construction, anticipated infiltration should be calculated. Information on how to calculate infiltration and how to use infiltration when calculating heat loads and losses can be found in the ASHRAE Fundamentals Handbook. The heat loads and losses calculated associated with infiltration are used in determining the latent cooling requirements. This will affect the volume of supply air necessary to maintain the design humidity levels in the room. Guidelines for determining the minimum ventilation requirements are given in ASHRAE Standard 62.1. Criteria for maximum relative humidity in the space, based on a humidity ratio of 0.012, is set in ASHRAE Standard 55; for a room design temperature of 75BF, the maximum relative humidity is 63.5%. Once the design conditions for room relative humidity have been determined the supply air flow rate necessary to maintain this level can be calculated. The required flow rate to meet the latent load can be determined by the following equation on the next page:

APPLICATION GUIDE

. V = the volumetric flow rate, CFM . q = latent heat gain in the space, BTU/H HRr = room air humidity ratio, lbs water/lbs dry air HRp = primary air humidity ratio, lbs water/lbs dry air It follows that the required flow rate to maintain control of the humidity will rapidly increase as the difference between the room air and primary air humidity ratios decrease. As a result, designs seeking to maintain relatively low humidity ratios will need a high primary flow rate if the dew point temperature of the supply air is close to the design dew point in the room. Comparing the required supply airflow rates for ventilation and to maintain the relative humidity of the space, the higher of the two flow rates will determine the minimum flow rate allowable for the space. If necessary the supply air flow rate can be increased to supplement the sensible cooling of the products selected. After the IAQ requirements have been tentatively set, the required equipment capacities to meet the heat loads and losses can are determined. Care should be taken to design around actual loads/losses that will be experienced in the space. Overdesigning the system will increase installation and equipment costs, and could potentially cause thermal comfort issues. Once the capacity requirements have been calculated, either supply air conditions or building design/ construction (if possible) can be adjusted to be more suited to chilled ceiling application.

PRODUCT SELECTION

The type of product to be used to is at the designer’s discretion. However the recommended limitations of maximum capacity per square foot should not be exceeded where high levels of thermal comfort are required.

There are several ways to operate these products to prevent condensation. The primary step to preventing condensation is for the chilled water design supply temperature to be at least 1BF above the dew-point temperature of the space. Also, the supply air to the space must also be sufficiently dehumidified to maintain the design relative humidity conditions. The secondary measures are noted below:

At this time the supply air temperature should be tentatively selected. Supply air temperature can be varied between cooling and heating, but most designs keep a fixed temperature as long as heating requirements can be met. The size and configuration of products selected should be completed while adjusting the following parameters: • Water flow rate: this should be selected to minimize pressure drop, should be no higher 10 ft w.g., while maintaining turbulent flow through the product. • Supply airflow rate: flow rate must be maintained above the minimum determined for IAQ requirements, but can be increased to offset the sensible cooling requirements of the product selected "" Increasing the flow rate in active beams while maintaining the same nozzle geometry will result in an increase of operating pressure. The recommended operating range is typically between 0.2 in w.g. and 0.8 in w.g. Operating pressure in active beams will also directly impact the noise generated by the product during operation. • Unit placement/Configurations: "" Radiant panels and sails: These products should be installed so that no more than 75% of the available ceiling space is made up of active panels/ sails. Panels models with perforated faces and backed with acoustic fleece insulation can be used to improve noise attenuation within the space. "" Passive Beams: Passive beams should not be installed directly above occupants since the highest velocities occurring from the convection process will occur directly underneath the beam. "" It is critical to the operation of passive beams that adequate space is provided for air flow through the beam. When installed in a flush mount application, shadow gaps, perforated ceiling tiles, dummy beams, or return air grilles must be installed so that warm room air enter the air path for the passive beams. It is recommended that the total free area for the return air path be at least 50% of the passive beam surface area. In exposed applications, the beams should be installed with a minimum distance between the top surface of the beam and the ceiling that is equivalent to half of the beam width, see Figure 7.

APPLICATION GUIGE

Once product type has been decided the entering water temperature should be selected such that condensation is prevented. The majority of chilled ceiling products do not include a means to collect or manage condensation. This means the temperature of the heat transfer surface, either water coil or panel/sail surface, must be higher than the dew-point temperature of the space to prevent the formation of condensation. However, to achieve the maximum cooling capacity the entering water temperature should be as low as possible. This can be difficult when trying to get the most capacity out of chilled ceiling products.

This measure should only be used in the event that an entire building is at risk for condensation.

Figure 7. Passive beam mounting height "" Active Beams: With the different configurations available in active beams, 1, 2, and 4-way beams a design can be implemented to effectively create a comfortable space. In open office spaces as well as internal offices 2-way or 4-way beams are typically used. The flexibility provided by 2-way and 4-way beams, due to multiple sizes and nozzle configurations, allow them to be appropriately applied in most applications. 1-way beams are typically used in perimeter zones and small spaces such as individual offices and hotel rooms.

www.titus-hvac.com | www.titus-energysolutions.com

"" After the throw pattern has been decided, placement of the beam within the space can be determined. Active chilled beams, because of their design, share throw characteristics with conventional slot diffusers. Placement and orientation of active beams is critical for thermal comfort due long throw values associated with active beams. In open office plans it is typically more cost effective to use several longer beams that are installed parallel to the long direction of conventional ceiling systems, instead of numerous smaller beams the length of the module division. (Figure 8, Openoffice Active Beam Layout) However in an open office the number and size of beams used will be determined by balancing the cost per beam, cost of air side operating pressure, and water side pumping power to achieve optimum energy efficiency. "" When applying 2-way and 4-way beams in small offices and individual offices the recommended location is directly above the occupants. This will result in the lowest velocities within the occupied space. It is also recommended that 2-way beams are installed lengthwise in the space. This will allow for the use of longer beams, reducing the cooling requirements per linear foot which will inturn lower total air flow per foot and the resulting velocities in the space ensuring occupancy comfort. If placement is required near a wall use of 1-way throw beams are recommended. 1-way beams can also be effectively used in perimeter zones for cooling applications; however they should be supplemented with baseboard heating to address window loads during the heating season. 2-way beams can be effectively applied in perimeter zones for both heating and cooling. Care must be taken if 2-way beams are installed parallel to windows. In intermediate seasons when internal cooling is required and window surfaces are cool an acceleration of the air can occur in the space creating drafts and potential discomfort.

In crosswise installations, there is typically one beam per module.

Occupied Zone

The minimum distance between units (2X) or minimum distance from a sidewall (X), can be determined by taking the difference between the diffuser's characteristic throw to 50 fpm (T50 ) and the distance between the ceiling and the occupied zone (Y). Figure 9. Local Velocity Diagram "" The ideal location for most active beams is directly above the occupant. This is because the lowest velocities in the space will occur in the induced air path. If it is desired to position an active beam close to a wall, a unit with an asymmetrical or 1-way throw pattern is recommended. As active chilled beams have throw characteristics similar to linear slot diffusers the same principles for determining thermal comfort conditions should be used. Location for final placement should take into consideration the allowable average air speed in the occupied space in accordance with ASHRAE Standard 55. Accounting for the air side sensible capacity will allow for reduced capacity requirements of the water coils in the beams. Designing with this in mind will reduce airflow requirements per linear foot, which will help to meet the requirements for thermal comfort. When placing two beams in the same space as shown in Figure 9, Local velocity diagram, care must be taken to ensure that the colliding air streams do not result in velocities over 50 fpm causing discomfort. A general guideline to achieve air velocities of 50 fpm or less in the occupied space is to ensure the velocities of colliding airstreams are below 100 fpm. If velocities at the point of collision are greater than 100 fpm, the distance from the ceiling for the air flow to slow to 50 fpm is noted in the equation below: Y=T50 - X Where: Y = distance from the ceiling X = half the distance to the adjacent diffuser T50 = diffuser characteristic throw to 50 fpm

CONTROL OF CHILLED CEILING SYSTEMS

Very basic room controls can be used with chilled ceiling systems. This is due to the fact that most systems are designed to operate with a constant volume of supply air. Also, the large coil size, combined with relatively low velocities across the coils result in a fairly long response time. With chilled beams or radiant systems, the most common method for controlling room temperature is regulating the water flow rate through the selected equipment. The alternative is to vary the supply water temperature. The control of water flow rate is achieved through onoff, time proportional on-off, or modulating control valve actuators. The maximum flow rate should be limited by a balancing valve installed on each beam circuit. It is generally recommended for 2-way valves to be used to reduce pumping costs, but 3-way valves can be used when pump speeds are not variable. While on-off and modulating actuator control is straight forward, time proportional on-off systems are a bit more complex. These systems use a feedback control loop to open and close an on-off actuator such that the total time open is proportional to the percentage of flow that is requested by a modulated room controller. While control of this system is more complex, actuator first costs are greatly reduced. Chilled beams should be connected in parallel so that each beam sees the same entering water temperature. For the greatest flexibility of control each beam should be fitted with an actuated control valve. With this setup, the flow rate can be modulated in each beam. And, in the event the entering water temperature reaches a point where condensation is a concern the flow rate to individual units affected can be shut

When designing systems with occupied/unoccupied modes or with night set back set ups. It is critical to ensure the design relative humidity conditions are met prior any water based sensible cooling. In most cases, 30 minutes of dryair ventilation will be enough to prevent any condensation during morning start-up and when returning to occupied modes. This can easily be achieved for night set back/ morning start up by offsetting the time schedules for the air handlers and chilled beam system pumps.

Alternatively to varying water flow rate through the beam, the entering water temperature can be varied according to the load in the space. This requires more sophisticated control sequences. Varying the water temperature also requires a bypass loop, that can inject higher temperature water from the return loop of the chilled beams or main air handler into the supply water loop for the beams.

• Standard finish is RAL 9010 white paint on diffuser face. • Diffuser is designed to fit into standard module ceiling grids 24” or 12” in width.

DESCRIPTION

The DISA active chilled beam diffuser was developed for removing high thermal loads from the space. Supplied with tempered and dehumidified primary air, to handle the latent load, the beam addresses the remaining loads in the space with a heat exchanger installed in the unit. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced the volume of air that must be delivered to the space results in reducing air handler capacity and size, smaller duct sizes, and overall energy savings. In the primary distribution channel, CNC formed nozzles are precisely arranged. The number and size of nozzles (A, B, C, D) can be varied, thus allowing optimum adjustment of the primary supply air volume. By reducing the primary air to meet the minimum requirements for either room ventilation or latent load in the space, whichever is greater, total system energy costs are reduced.

DISA

The primary air, supplied by the air distribution system is supplied to the mixing chamber via induction nozzles. In the mixing chamber, room air is induced over a horizontally mounted heat exchanger, to address sensible loads in the space. The primary air is mixed with the cooled secondary air and supplied to the room through 1- or 2-slot diffusers integrated into the unit design. The DISA chilled beams are available in a multitude of configurations, resulting in produces that easily integrate into any building or design. These products have been designed to address heating and cooling loads in the space, with either a 2-pipe or 4-pipe system. The low overall height of the DISA product line is ideal for reducing the space required for false ceilings in new buildings and for retrofit applications.

INSTALLATION

U18

In order to achieve a uniform cooling capacity, the beams should be connected to the cold water distribution system

in parallel. It is recommended that DISA chilled beams are connected to a supply air duct system which controls the supplied primary air volume. When integrated with room controllers, the units can be used both for single room and zone control.

ADVANTAGES • Removal of high thermal loads is possible in this air/water system. • The height of the air duct system is reduced to a minimum, due to the low supply of primary air. • Substantial reduction in the operating costs, due to low primary air volume. • Improvement of the thermal comfort inside the room. • Individual adjustment of the primary air volume by means of the nozzle configuration A, B, C, D. • Suitable for all standard ceiling grids.

Linear Active Chilled Beams (continued)

• DISA-V is a linear sidewall active chilled beam diffuser with horizontal air distribution. DISA-V

• Unique linear design provides high induction and low noise levels. • Configurable as cooling & supply air (CO) or cooling, heating & supply air (CH) configurations. • Available as diffuser shell (no coil/piping). • Accessories include rubber lip seal.

• Standard finish is RAL 9010 white paint on diffuser face. • Diffuser is designed to be recessed into a sidewall, soffit or bulkhead.

DESCRIPTION

INSTALLATION

The DISA-V sidewall active chilled beam diffuser was developed for removing high thermal loads from the space. Supplied with tempered and dehumidified primary air, to handle the latent load, the beam addresses the remaining loads in the space with a heat exchanger installed in the unit. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced the volume of air that must be delivered to the space results in reducing air handler capacity and size, smaller duct sizes, and overall energy savings.

In order to achieve a uniform cooling capacity, the beams should be connected to the cold water distribution system in parallel. It is recommended that DISA-V chilled beams are connected to the supply air duct system which controls the supplied primary air volume. When integrated with room controllers, the units can be used both for single room and zone control.

In the primary distribution channel, CNC formed nozzles are precisely arranged. The number and size of nozzles (A, B, C, D) can be varied, thus allowing optimum adjustment of the primary supply air volume. By reducing the primary air to meet the minimum requirements for either room ventilation or latent load in the space, total system energy costs are reduced. The primary air, supplied by the air distribution system is supplied to the mixing chamber via induction nozzles. In the mixing chamber, room air is induced through a vertically mounted heat exchanger, to address sensible loads in the space. The primary air is mixed with the cooled secondary air and supplied to the room in a horizontal throw pattern through 1-slot diffuser integrated into the unit design.

DISA-V

ADVANTAGES • Removal of high thermal loads is possible in this air/water system. • The size of the supply duct system is minimized due to reduced primary air requirements. • Substantial reduction in the operating costs due to low primary air volume. • Improved thermal comfort inside the space. • Individual adjustment of the primary air volume by means of the nozzle configuration A, B, C, & D. • Suitable for all standard ceiling grids.

DISA-V

The DISA-V chilled beams are available in a multitude of configurations, resulting in produces that easily integrate into any building or design. These products have been designed to address heating and cooling loads in the space, with either a 2-pipe or 4-pipe system. The construction of the DISA-V product line is ideal for installation in soffits and sidewalls where ceiling space is limited. The horizontal throw pattern is enables comfortable cooling to be delivered to small spaces by effectively rolling without creating drafts.

SPECIFICATIONS

2.02 GENERAL

U42

A. It is the design intent of these specifications to provide a fully integrated HVAC system with all parts working together. These induction units need clean, dehumidified primary air from a dedicated outdoor air unit, hot and chilled water from a boiler and chiller, piping, and controls to coordinate each component to perform as intended. Changes, modifications, or substitutions on any component will impact all the other parts of the system and cannot be made without a careful review of all related specifications. B. Chilled beam unit shall be constant volume primary air flow units designed to induce a secondary airflow within the conditioned space using the primary conditioned air supply. Units shall be designed for ceiling installation with factory supplied hanging brackets. Hanger rods or other approved hanging system to be field supplied and installed in the field by installing contractor. C. Units shall be equipped with a round low velocity pres-

sure inlet transition, one air plenum and air induction nozzle plate, a supply and return chilled water piping connection, one supply and return hot water piping connection, and one combination supply/return air grille for effective room air distribution. The grille shall be hinged and secured in place with tool-less safety fasteners to provide full access to the return air side of the coil. The unit shall be capable of inducing the secondary airflow within the conditioned space using the velocity pressure of the primary airflow. This secondary air must flow directly from the room to the unit and shall not use the ceiling as a return air plenum. Active beam units using the ceiling plenum as a return air path are not acceptable. D. Each unit shall be equipped with a multiple row water coil for chilled water and hot water. Latent conditioning of the air supplied to the space shall be performed at the dedicated outdoor air unit and controlled by exhaust air humidity sensors.

2.03 CASINGS

A. The entire unit shall be constructed of 20 gauge galvanized G90 sheet metal. The primary air plenum and nozzles shall be designed and configured to provide uniform air distribution with low noise operation to all nozzles.

DESCRIPTION

INSTALLATION

The LCBS 1-way active chilled beam diffusers are designed for removing high thermal loads from the space. Supplied with tempered and dehumidified primary air, to handle the latent load, the beam addresses the remaining loads in the space with a heat exchanger installed in the unit. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced the volume of air that must be delivered to the space results in reducing air handler capacity and size, smaller duct sizes, and overall energy savings.

In order to achieve a uniform cooling capacity, the beams should be connected to the cold water distribution system in parallel. It is recommended that LCBS units are connected to the supply air duct system delivering a constant volume of primary air to maintain optimum induction. When integrated with room controllers, the units can be used both for single room and zone control.

In the primary distribution channel, high density polyethylene injection molded nozzles are precisely arranged. There are three available nozzle sizes allowing optimum selection of the primary supply air volume. By reducing the primary air to meet the minimum requirements for either room ventilation or latent load in the space, total system energy costs are reduced.

The LCBS chilled beams are highly configurable, making them the perfect solution for all applications. These products have been designed to address heating and cooling loads in the space, with either a 2-pipe or 4-pipe system. LCBS units are supplied with a dew-point safety pan and are available with optional safety overflow switches.

CLEANING OF THE GRILLE/COIL To clean the grille and the coil, locate spring loaded retaining pins. Slide diffuser face towards spring retainers until pins on opposite side clear the unit frame. Diffuser face will now be able to swing down for removal. Do not use any scouring agents for cleaning these components; damage to the unit construction materials (galvanized steel, aluminum and copper) and the surface coatings (paint and anodized surfaces) may occur. After completion of maintenance, grille must be returned to its original operating position.

LCBS

The primary air, supplied by the air distribution system is supplied to the mixing chamber via induction nozzles. In the mixing chamber, room air is induced over a vertically mounted heat exchanger, to address sensible loads in the space. The vertical orientation of the coil allows for induction through all sides of the water coil. The primary air is mixed with the cooled secondary air and distributed in to the room through a 1-way multiple louver diffuser supplied with the unit.

• TCM2 is a modular active chilled beam diffuser with 4-way air distribution. TCM2

• Diffuser face on 48” x 48” unit is shipped loose for field mounting. The 24” x 24” unit ships complete.

• Supply/Return diffuser removable with out tools; providing access to interior of unit.

• Factory supplied hanging brackets.

• Accessories include disposable or washable filter, and plenum rated float switch for drain pan.

• Casing constructed of 20 GA galvanized steel. • Closed cell, anti-microbial poly foam insulation.

• Standard finish is #26 white paint on diffuser face.

DESCRIPTION The TCM2 4-way active chilled beam diffusers are designed for removing high thermal loads from the space. This model was designed specifically to meet the unique requirements of high population density spaces; depending on the unit size, the TCM2 can handle between 60 and 475 CFM of ventilation (primary) air. Supplied with tempered and dehumidified primary air, to handle the latent load, the beam addresses the remaining loads in the space with a heat exchanger installed in the unit. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced the volume of air that must be delivered to the space results in reducing air handler capacity and size, smaller duct sizes, and overall energy savings. In the primary distribution channel, high density polyethylene injection molded nozzles are precisely arranged. There are three available nozzle sizes allowing optimum selection of the primary supply air volume. By reducing the primary air to meet the minimum requirements for either room ventilation or latent load in the space, total system energy costs are reduced.

The TCM2 chilled beams are highly configurable, making them the perfect solution for all applications. These products have been designed to address heating and cooling loads in

the space, with either a 2-pipe or 4-pipe system. TCM2 units are supplied with a dew-point safety pan and are available with optional safety overflow switches.

INSTALLATION In order to achieve a uniform cooling capacity, the beams should be connected to the cold water distribution system in parallel. It is recommended that TCM2 chilled beams are connected to the supply air duct system delivering a constant volume of primary air to maintain optimum induction. When integrated with room controllers, the units can be used both for single room and zone control.

ADVANTAGES • Removal of high thermal loads is possible in this air/water system. • Designed to accommodate the ventilation requirements of high population density areas. • The size of the supply duct system is minimized, due to reduced primary air requirements. • Substantial reduction in the operating costs, due to low primary air volume. • Improved thermal comfort inside the space. • Individual adjustment of the primary air volume by means of the nozzle size. • Suitable for all standard ceiling grids.

Chilled Beam

• SPB is a linear passive chilled beam diffuser.

SPB

• Unique design accommodates both recessed and exposed mounting. • Available in 2-pipe configuration. • Available as diffuser shell (no coil/piping). • Standard finish is RAL 9010 white paint on diffuser face.

DESCRIPTION Passive chilled beams are primarily used to provide comfortable sensible cooling, and can be used in many heating applications as well. The primary mode of heat transfer is by convection, with a percentage of heat transfer transmitted through radiation. During cooling, warm room air rises to the ceiling area; cool air around the coil sinks down to the occupied area as a result of the higher density. As the cool air descends in to the space, more warm air is drawn over the coil creating a convective current that drives the system. The exposed face of the passive beam is constructed from either painted perforated stainless steel, or a linear bar grille. The cooling strips are available in lengths of 4 feet to 14 feet in intervals of 2 feet. The beams are designed for integration into a suspension ceiling or for exposed mounting, suspended below the ceiling surface.

ADVANTAGES • SPB models designed to accommodate recessed or exposed installation with a single model. • Easy cleaning of the water coil and the housing. • Quick and simple installation. • Provide comfortable, effective heating and cooling to the space.

The diagram shows the approximate cooling capacity Pc in BTUH at a water flow rate of 0.8 gpm and a temperature difference between room air and the average water temperature of 14.5° F.

MOUNTING INFORMATION Mounting brackets that can slide along the longitudinal axis are mounted on the beam, 2 per beam. Alternatively, mounting shackles can be provided with are fastened to the beam and rest on the T-shaped support profiles of the false ceiling having a center-to-center distance of 600 mm. This reduces the mounting time as well as the mounting costs. The number of shackles required per beam, depending on length, is noted in the table below. Beam Length

A correction must be made to the beam performance based on the diagram below to adjust for water flow rates other than 0.8 gpm is K = Pc1.3 vs Pc0.8 = 1.04. Thus, due the higher amount of water, the actual capacity is 4% higher than the value shown in the diagram. Pc = 1.04 x 215 = 224 BTUH/ft. Required effective length (coil length) Leff = 2400/223 = 10.8ft.

Solution: Mean coil temperature = (57+61)/2 = 59BF Difference between room air temperature and mean coil temperature Dt = 75-59 = 16BF. According to the diagram below, the cooling capacity, PC0.8 for the 17-inch wide beam at a water flow rate of 0.8 gpm is 215 BTUH/ft. (BTU/Hr.ft)

Minimum unit length = 10.8ft + .3ft = 11.1ft. The next larger beam length, of 12 feet will be required to provide the required cooling in the space.

• Constructed from extruded aluminum profiles. • Single circuit for each sail as ordered; hard copper connection between individual blades. • Standard finish is RAL 9010 white powder coating.

ALPETY HKL

ALPETY FKL

• FKL and HKL are architectural radiant ceiling products.

• Supplied with mounting equipment for fixed on site installation. • Available with hinged mounting equipment allowing sails to swing down up to 45B.

• 15mm diameter pipe connections.

DESCRIPTION The Alpety radiant ceiling systems are water driven radiation systems whose advantages include silent cooling, low energy consumption, and create a high degree of thermal comfort through draft free cooling and even temperature distribution in the space. However, it must be taken into account that these systems must be supported by additional mechanical ventilation and means to address the latent cooling requirements of the space.

ADVANTAGES • Radiant heat transfer increases occupancy comfort. • Reduces energy consumption by utilizing heat transfer capacity of water. • Minimize airflow and noise in the space. • Quick and simple installation. • Several models integrate seamlessly in to any architecture.

ALPETY (FKL, HKL)

Radiant ceilings systems emit heating and cooling by both convection and radiation. During cooling, ambient air near the ceiling cools and falls to the occupied area, due to its higher density. In contrast, the ambient air heated by heat sources located in the room will rise. This gives rise to convection currents with very low flow velocities. Furthermore, the ceiling emits cooling and heating to the surrounding surfaces in the area by radiation. When radiation reaches one of these surfaces, the radiant energy is absorbed by that surface. The radiant heat transfer from the panels to surfaces and/or occupants in the room will occur regardless of the ambient air temperature. Radiant heat transfer results in high thermal comfort and leads to the ambient temperature feeling cooler than it actually is during cooling and warmer in heating. Depending on the percentage of the active ceiling surface to the overall surface of the room (including floor, walls, windows, furniture, etc.) the temperature perceived by the occupant will be 2.5 to 5 degrees cooler/warmer than it actually is. This effect has the advantage that the room requires less conditioning than a traditional system, introducing an additional opportunity for energy savings.

In conjunction with the customer’s own metal or acoustic ceiling tiles, the Alpety ceiling elements can be integrated in the room to create the ceiling façade, models FKL and HKL, or in combination with suspended ceiling systems with SKS models. The individual ceiling elements are usually joined to one another using flexible hoses. Connections can also be made using hard copper piping and soft soldering.

www.titus-hvac.com | www.titus-energysolutions.com

Radiant Ceiling Panels ALPETY (FKL, HKL)

Since the sensible cooling no longer has to be introduced into the room along with ventilation air, the volume of air supplied can be reduced to the meet the fresh air requirements. By reducing the volume of air supplied the possibility of drafts and noise levels are greatly reduced. This leads to increased occupancy comfort. Addressing thermal loads using the Alpety products makes use of the increased heat transfer capacities of water, as compared to air, increasing overall system efficiency.

Radiant Ceiling Panels (continued)

• SKS panels are architectural radiant ceiling products. ALPETY SKS

• Constructed from aluminum or steel sheet metal, aluminum extrusion, and copper tubing. • Optional perforated face pattern includes acoustical fleece to enhance room sound absorption. • Single water circuit per panel. • 15mm diameter pipe connections.

• Available mounting brackets and support rails for easy field installation.

ADVANTAGES

• Radiant heat transfer increases occupancy comfort. • Reduces energy consumption by utilizing heat transfer capacity of water. • Minimize airflow and noise in the space. • Quick and simple installation. • Several models integrate seamlessly in to any architecture.

ALPETY SKS

Radiant ceilings systems emit heating and cooling by both convection and radiation. During cooling, ambient air near the ceiling cools and falls to the occupied area, due to its higher density. In contrast, the ambient air heated by heat sources located in the room will rise. This gives rise to convection currents with very low flow velocities. Furthermore, the ceiling emits cooling and heating to the surrounding surfaces in the area by radiation. When radiation reaches one of these surfaces, the radiant energy is absorbed by that surface. The radiant heat transfer from the panels to surfaces and/or occupants in the room will occur regardless of the ambient air temperature. Radiant heat transfer results in high thermal comfort and leads to the ambient temperature feeling cooler than it actually is during cooling and warmer in heating. Depending on the percentage of the active ceiling surface to the overall surface of the room (including floor, walls, windows, furniture, etc.) the temperature perceived by the occupant will be 2.5 to 5 degrees cooler/warmer than it actually is. This effect has the advantage that the room requires less conditioning than a traditional system, introducing an additional opportunity for energy savings.

• Standard finish is RAL 9010 white powder coating.

ACCESSORIES

Fan Coils

Wireless Accessories Most ECM motors currently in the market have a 70% motor efficiency at full and partial loads which substantially reduces Energy costs. The ECM motor also has the ability to modulate the airflow to meet partial load requirements thereby further reducing the energy requirements of a building. The low operating temperature of the ECM motor also requires very little energy to offset the heat gain from the motor to the cooled airstream, thus also reducing the building energy requirements.

The modulated valve actuator control device increases Chiller and Boiler efficiency by 15-20% with substantial energy savings by meeting exact conditioned space load requirements. The overall net effect of modulated control valves adjusting the water flow rate to meet occupied space load requirements as they change, is increased occupant comfort in the conditioned space while reducing system energy costs.

One of the easiest ways to save energy and money is to upgrade to a programmable thermostat. These thermostats allow the fan coil unit to be programmed to run only at specific times of the day at specific temperatures. Programming the thermostat to shut down or reduce the cooling/heating demands during periods of time when the occupant is typically away will quickly begin reducing costs after installation. The occupant can always temporary override the program during these times if necessary.

ACCESSORIES

An alternative to improving the efficiency and energy consumption of the fan coil unit is to install a programmable thermostat with occupancy sensors or a keycard. The thermostat can be programmed to gradually reduce the cooling/ heating demand to a pre-specified point if an occupant is not present. By using these sensors in conjunction with a programmable thermostat, tighter control of the energy consumption of a fan coil unit can be maintained.

Overview

Four different models available in numerous configurations, delivers a unit tailored to meet the needs of any project. Horizontal ceiling mounted units typically are used in applications that exceed the requirements of direct drive fan coils products. Rooftop units are installed externally introducing fresh air into the system. Vertical units are

generally installed in maintenance closets or mechanical rooms near the zones they serve so maintenance or service can be performed without intruding on the occupants. The modular unit is extremely flexible and can be adapted to meet most supply and return configurations. Titus Air Handlers can operate with 100 percent outside air, 100 percent recirculated air, or anywhere in between. All models are designed to allow easy access to all components for maintenance and service. Fan motors are installed on a variable pitch mounting plate allowing for fine tune balancing of the system in the field.

PERFORMANCE DATA

Notes: 1. Motor HP = 1.15* x BHP * In the absence of a specified drive loss factor, use 1.15. To select motor size, find the Brake Horsepower (BHP) for the design cfm and External Static Pressure (ESP). Multiply BHP by 1.15 (or specified factor) and round up to next size motor. Example: 1600 cfm at 0.75-inch ESP requires 0.70 BHP. 1.15 x 0.70 = 0.805. Round up to nearest nominal motor size = 1 HP. 2. Total Static Pressure (TSP) = Internal Static Pressure + External Static Pressure (ESP) 3. ESP = TSP – Internal SP

Notes: 1. Motor HP = 1.15* x BHP * In the absence of a specified drive loss factor, use 1.15. To select motor size, find the Brake Horsepower (BHP) for the design cfm and External Static Pressure (ESP). Multiply BHP by 1.15 (or specified factor) and round up to next size motor. Example: 1600 cfm at 0.75-inch ESP requires 0.46 BHP. 1.15 x 0.46 = 0.529. Round up to nearest nominal motor size = 3/4 HP. 2. Total Static Pressure (TSP) = Internal Static Pressure + External Static Pressure (ESP) 3. ESP = TSP – Internal SP

Notes: 1. Motor HP = 1.15* x BHP * In the absence of a specified drive loss factor, use 1.15. To select motor size, find the Brake Horsepower (BHP) for the design cfm and External Static Pressure (ESP). Multiply BHP by 1.15 (or specified factor) and round up to next size motor. Example: 1600 cfm at 0.75-inch ESP requires 0.46 BHP. 1.15 x 0.46 = 0.529. Round up to nearest nominal motor size = 3/4 HP. 2. Total Static Pressure (TSP) = Internal Static Pressure + External Static Pressure (ESP) 3. ESP = TSP – Internal SP

PERFORMANCE DATA

Notes: 1. Motor HP = 1.15* x BHP * In the absence of a specified drive loss factor, use 1.15. To select motor size, find the Brake Horsepower (BHP) for the design cfm and External Static Pressure (ESP). Multiply BHP by 1.15 (or specified factor) and round up to next size motor. Example: 1600 cfm at 0.75-inch ESP requires 0.46 BHP. 1.15 x 0.46 = 0.529. Round up to nearest nominal motor size = 3/4 HP. 2. Total Static Pressure (TSP) = Internal Static Pressure + External Static Pressure (ESP) 3. ESP = TSP – Internal SP

The values of full-load currents are for motors running at usual speeds and motors with normal torque characteristics. Motors built for especially low speeds or high torques may have higher full-load currents, and multi-speed motors will have full-load current varying with speed, in which case, the nameplate current rating shall be used. The voltages listed in the table are rated motor voltages. The currents listed shall be permitted for system voltage ranges of 110 to 120 and 220 to 240 volts. Values presented are from the NEC Handbook, 1999 Edition. Actual motor nameplate amps may vary.

FULL-LOAD CURRENTS IN AMPERES, THREE-PHASE ALTERNATING-CURRENT MOTORS

The values of full-load current are typical for motors running a speed usual for belted motors and motors with normal torque characteristics. Motors built for low speeds (1200 RPM or less) or high torques may require more running current, and multi-speed motors will have full-load current varying with speed. In these cases, the nameplate current rating shall be used. The voltages listed are rated motor voltages. The currents listed shall be permitted for system voltages ranges of 110 to 120, 220 to 240, and 400 to 480. Values presented are from the NEC Handbook, 1999 Edition. Actual motor nameplate amps may vary.
