Ascotherm® eco General information

General information In pure heating or cooling systems, the thermal comfort is primarily influenced by the air temperature and thermal radiation. If a person finds these aspects to be optimal, thermal comfort is given. For the dimensioning of a system, the exterior walls and window surfaces are of particular importance. The greatest differences between the surface temperature and room temperature usually occur at these two room-defining surfaces. At exterior walls, thermal insulation is used in order to minimise this difference. In case of window areas, insulating and heat-saving glazing is the standard today. Because of material properties, however, the inside surface temperature is nevertheless lower than the room temperature.

A carefully planned dimensioning of trench convectors for cooling leads to the following results: 1. Rising warm air at the window pane which is caused by absorption of the solar irradiation, results in heat transport into the room. In order to counteract to this effect the trench convector generates an opposing flow. 2. In addition, the indoor surface temperature of the glazing is reduced. And a comfortable relationship between the surface temperature of the window especially the window areas and the room temperature is created.

Step 1: Determination of the surface temperature ΔTu of the window depending on the indoor temperature compared to outdoor

This creates the following three effects:

Depending on the structural possibilities, conductors are used in such cases. In this case, our Ascotherm eco trench convectors come to the fore. In addition to having a design suited to any particular needs, they give architects a free hand. A carefully planned dimensioning of trench convectors for heating leads to the following results: 1. Cold air draught and cold air flows can be prevented entirely. This requires that the trench convectors extend across the entire width of the window and provide sufficient heat output. 2. The radiated portion towards the cold surface of the window is reduced, since the convection initiated by the convector warms the cold surface. 3. Condensation on the window surface can also be prevented. This requires that the temperature directly at the window pane doesn´t drop at or below the temperature of dew point. The warm rising air prevents cooling of the air in the boundary layer; at the same time, the indoor surface temperature of the window area increases. In the case of cooling, it is necessary to consider the abovementioned effects separately. The objective here is to counteract the thermal radiation due to the solar irradiation and at the same time keep the room temperature at the intended value. Our Ascotherm eco KC designs are predestined for this. Although these convectors are intended primarily for cooling, they can also be used for efficient room heating.

Indoor temperature ΔTi = Ji ,A - Ja = Ji ,A - J’i [K] Ji ,A = Indoor design temperature in °C Ja = Outside temperature in °C Uu = Heat transfer coefficient of the enclosing surface W/(m² K)

Example: Indoor design temperature: Outside temperature: U-value of window: > Indoor excess temperature: Result ΔTu:

20 °C - 10 °C 1 W/m² K 30 K Subnormal temperature 3,8 K

Step 2: Determination of the maximum velocity of descending air Vmax depending on the subnormal temperature ΔTu and the window height H 1 0,9 0,8 0,7 Velocity of descending air Vmax [m/s]

1. Cold air drop and cold air flow The room air cools at the colder surface of the window and sinks. The intensity of this effect is primarily affected by the height of the window area, the outside temperature and the heat transfer coefficient of the glazing (U-value). Moreover, the flow of cold air can extend several metres into the room and cause discomfort. 2. Radiation A cold window surface causes uncomfortableness. The individuals in the room radiate heat towards the cold window surface which is sensed as discomforting even if the room temperature is in a comfortable range. 3. Condensation forms on the windows When the temperature drops below the dew point temperature in the boundary layer (directly at the surface of the glazing), water condenses on the cold surface of the window. The objective is to prevent these three effects.

Ascotherm® eco KRN92 Natural convection with air connection Tender specification, range available and sizes

Tender specification Version KRN92 Natural convection with air connection Ready-to-install floor pans for the floor area. Operating principle: Convection with air connection. Sturdy floor pan made of galvanised sheet steel, coloured in anthracite grey (RAL 7016), external, adjustable and acoustically decoupled height adjustments (pre-installed). Heat register made of copper pipes and aluminium fins, anthracite grey (RAL7016) coated and mounted in transversal steel girder made of galvanised sheet steel, acoustically decoupled.

Ascotherm eco KRN92

Standard to the face or room side euro taper connection with union nut (3/4“ internal thread) and air vent. Suitable for a max. operating pressure of 10 bar (optionally 16 bar) and a max. operating temperature of 110 °C. Air duct mounted on the room side along the entire ribbed convector length, with integral supply air connection and slide valve to regulate the air volume rate. The incoming air is distributed evenly over the entire length of the air duct. The size of the supply air connections depends on the height of the floor pan. In addition, the size and number of supply air connections are determined by planners on the basis of the air flow rates.

Operating principle Cool room collects in the floor pan. The air is heated by the heat register, becomes lighter and rises. Installation in front of window areas provides a specific shielding against cold air. For more information, see chapter the "General information".

Aluminium linear grille as standard. Acoustic decoupling through placement of the aluminium linear grille on rubber elements in the floor pan. Consisting of sturdy longitudinal profiles, natural colour anodised, with profile bar dimensions of 16 x 6 mm. Grille with a total height of 20 mm and an open cross-section of 60%. Including installation cover and edge bar protection for protection of the trench convectors during the construction phase. QA system certified to DIN EN ISO 9001:2008. Environmental management system to DIN EN ISO 14001:2004. Operating conditions: Hot water up to 110 °C Operating pressure: Max. 10 bar (optionally 16 bar high-pressure-version) Test pressure:

13 bar (21 bar)

Ascotherm® eco KC281 Heating and cooling in 2-conductor system Tender specification, range available and sizes

Tender specification Version KC281 heating and cooling in 2-pipe system Ready-to-install floor pans for the floor. Operating principle: Forced convection with cross-flow fan for heating and cooling in 2-pipe system. Sturdy floor pan made of galvanised sheet steel, coloured in anthracite grey (RAL 7016), external, adjustable and acoustically decoupled height adjustments (pre-installed). Condensate pan integrated in the floor pan, incl. two drain connections (Ø 15 mm) on the sides. Register made of copper pipes and aluminium fins, anthracite grey (RAL7016) coated and mounted in transversal steel girder of galvanised sheet steel, acoustically decoupled. Standard to the face or room side euro taper connection with union nut (3/4“ internal thread) and air vent. Suitable for a max. operating pressure of 10 bar (optionally 16 bar) and a max. operating temperature of 90 °C. Cross-flow fan already installed in the floor pan parallel to the heat register (cross-flow fan on window side). Protective cover over the cross-flow fan. Cross-flow fan with energy-saving EC motors 24 V, wired ready for connection.

Operating principle Forced convection for heating Cold air from the window areas and cooled air are drawn in and transported through the heat exchanger. Ascotherm eco KC281

Heated air rises. Installation in front of window areas provides a specific shielding against cold air. For more information, see chapter "General information" Forced convection for cooling Warm air is drawn in, cooled in the register and discharged into the room as cooled air. Installation in front of window areas provides a specific shielding against the thermal radiation due to solar irradiation. For more information, see chapter "General information".

Low-noise fan operation, infinitely variable via analogue interface (0 – 10 V). Actuator control pulse 24 V DC, infinitely variable via analogue interface (0 – 10 V). Synchronised control of fan speed and water flow for a hydraulically balanced pipe system and especially energy-efficient operation while maintaining a minimum spread between flow and return temperature. Factory configuration of appropriate control algorithm. Aluminium roll-up grille as standard. Acoustic decoupling through placement of the aluminium roll-up grille on rubber elements in the floor pan.

Ascotherm® eco Product details Control system

Control system

Control characteristics / functional overview

In the course of converting from AC to EC technology for the Ascotherm eco fan motors, a powerful and innovative control system was developed. The new Ascotherm eco control system conforms to the growing demands for both modern single-room control and connection to a building management system via a KNX BUS.

• Infinitely variable control of the fan speed in relation to the room's heat requirement (difference between set temperature and room temperature) • Synchronised control of fan speed and valve stroke (water flow) for a hydraulically balanced pipe system and especially energy-efficient operation (maintenance of a minimum spread between flow and return temperature). According to a preliminary study conducted by Prof. Dr.-Ing. Rainer Hirschberg, University of Aachen, this can save 8% of the thermal energy and more than 80% of the electrical energy (recirculation) compared to systems without synchronised control.

In a standard situation, only the mains supply (220-240 V AC, conductor cross-section of at least 1,5 mm²) and the communication line to the Ascotherm eco room thermostat (wire cross-section 0,25 mm², twisted-pair conductors, max. permissible line length 30 m) need to be connected on site. Depending on the configuration and type of optional control components, the following additional external connections can be provided on-site: • Internal bus line to additional convectors in a combined control system (up to 6 convectors), wire cross-section at least 0,25 mm², max. permissible line length 100 m • Bus line to a higher-level building management system, wire cross-section at least 0,25 mm², max. Permissible line going 700 m between Ascotherm eco with KNX plug-in card and IP router • Line connection to an external room temperature sensor • Line connection to an RF receiver (for receiving input signals from window contact sensors and presence detectors) The following optional control components are wired inside the floor pan.

Every Ascotherm eco trench convector is supplied with all control parameters preset at the factory. Depending on the situation (e.g. control with or without a building management system), convector type and individual needs of the customer, control system parameters can be set during commissioning with the aid of an Ascotherm eco room thermostat (see accessory ZE00770003).

Valve stroke

• Automatic fast heating outside the "comfort range" (+/- 0,5°C of the set temperature) – may be deactivated by means of a parameter • Adjustable limit of the fan speed within the "comfort range" • "Quiet heating" (without fan operation) in the lower output range • Frost protection function via room temperature sensor • Connection to a building management system possible via an optional KNX plug-in card (only one per combined control system needed)

Connection can be made at the factory (with a corresponding order) or by the installer: • Thermoelectric actuator 24 V DC, control voltage 0-10 V DC • Surface sensor for flow temperatures (possible for heating and cooling circuits on the KC481) • Dew point sensor (KC281 and KC481) • KNX plug-in card For more detailed information about electrical connections, see the electrical installation instruction.

Attention was also payed to ensure easy installation during development of the control system. The control board is compatible with all Ascotherm eco trench convectors having EC cross-flow fans (KRN81, KC281, KC481) and already installed at the factory in a casing with protection class IP65. The installed electrical components are already completely wired and thus ready for connection upon arrival from the factory. Customer-specific upgrades of the system in the form of various signal inputs and outputs (plug-in contacts) are possible at any time.

Paint finishes Stoved enamel powder coating (packaged) in all RAL colours according to customer specifications; colour deviations customary in the industry are possible. Use only original RAL colour samples for colour matching. For production reasons, paint finishes are subject to slight colour deviations, caused in part by specific light conditions. There may also be differences when comparing painted surfaces with painted ceramic products. Because of limitations in the printing process, the illustrated colours are not binding. The floor pans and possibly aluminium grilles are finished in accordance with DIN 55900. They must be transported with care and protected against damage at the construction site. Noises Noise emission depends on the design, size and fan speed. The acoustic power levels were measured using DIN 45635-1 as a reference. According to E DIN EN 16430-1 (Fan-assisted radiators, convectors and trench convectors - Part 1: Technical specifications and requirements), the sound pressure level can be defined with a room absorption of 8 dB(A). This corresponds to a distance of 2 m from the tested unit, a room volume of 100 m3 and a reverberation time of 0,5 s. The acoustic characteristics of the room influence the noise level. Accordingly, the actual values may differ. It is recommended that the Ascotherm eco be designed for operation at a moderate speed.

Unless an operating pressure is specified, the standard version will be provided. Water quality Operating conditions for water quality in accordance with VDI 2035 must be maintained just as the industry-standard installation rules. Warranty claims according to our General Terms of Sale, Delivery and Payment shall be invalid in the event of: • periodic or extended draining of the system • operation with steam • addition of substances (e.g. chemicals, antifreeze) to the heating water that can have a corrosive effect on copper or sealing materials • excessive sludge deposition in the trench convector • occasional or constant drag-in of oxygen into the system (e.g. lines and pipes that are not sealed against diffusion) • leaks in the heating system

Further information

Special versions according to drawings If necessary, the customer receives a dimensional drawing for review and approval; the order will be produced after this is returned. In the event that the order is cancelled, the customer must pay compensation for the services and costs incurred up to that point.

4. Acoustic power level

Sources of noise cause the air to oscillate; it compresses and expands alternately.

The acoustic power level LW is defined by:

These pressure changes dither the existing air pressure and propagated through the air in sinusoidal form. When these pressure fluctuations reach our ear, the air pressure waves are transformed into mechanical vibrations by the eardrum.

LW =

10 lg

( ) P P0

in dB

The process of hearing is begun.

P = Acoustic power in watts

The human ear only senses the airborne sound; the following two factors are decisive:

P0 = Reference power, specify internationally at 1 x 10-12 watts

a: Sound pressure

The sound pressure level is the sound generated at the sound source (the energy transmitted to the air), while the acoustic pressure level is the sound registered at a certain distance from the sound source.

b: Frequency

Thus generally the acoustic power level is larger than the acoustic pressure level.

1. Sound pressure The sound pressure is the change in pressure of the air caused by a sound source. These pressure fluctuations are measured in N/ m², and are designated with the letter p. The sound pressure is a measure of the sound level. It depends on the distance between the sound source and the measurement location as well as the properties of the room. The sound pressure is unsuitable for calculating the expansion of sound on the sound propagation paths. For this it is necessary to determine the acoustic power of the sound source. 2. Acoustic power The energy converted into sound by a component (sound source) is called acoustic power. This acoustic power is transmitted to the air in the form of pressure fluctuations. The acoustic power is a value that cannot be measured directly. It is determined by integrating the acoustic pressure over a hemispherical or spherical surface about the sound source. The acoustic power is thus a value that is independent of space and distance. It will be used for all of the following calculations.

5. Frequency assessment Humans perceive the same sound pressure level differently at different frequencies. A sound pressure level is generally perceived as quieter and less annoying at low frequencies than at higher frequencies. In order to take this subjective perception into account, the objectively measured sound pressure levels are adapted to the perception of sound levels. This is called assessment of the sound pressure level. This assessment is done by subtracting a certain amount from the measured sound pressure level for frequencies that humans are less sensitive to, while adding a certain amount in the other frequency ranges. Of the various assessments, the A-weighting has become virtually the only one used. This provides information in the form of a single figure that is designated as an A-weighted acoustic pressure level or an Aweighted sound pressure power. The unit is called db[A].

The acoustic power is stated in watt [W]. For practical use, dimensionless figures have been introduced based on the work of A. G. Bell. 3. Sound pressure level The logarithmic relationship of a sound pressure p to the reference value p0 is designated acoustic pressure level LP; the unit used to specify it is the decibel [dB].

Lp

=

10 lg

( ) p p0

2

6. Sound level additions If several sound sources are present, then the corresponding levels have to be added to form a total sound level. The same principles apply here for both the sound pressure level and the acoustic power level. When there is more than one sound source with the same level, the following relationship applies: Ltot = L1 + 10 x log n [dB]

p = Effective value of the sound pressure at a certain spot in the room

Further information

p0 = Reference sound pressure, specified internationally at 2 x 10-5 N/m²

The cooling load of buildings is calculated on the basis of VDI 2078.

5) KC281 with L = 2000 mm, H = 155 mm, T = 360 mm, Dimensioning with control voltage of 5 V PKN = 1256 W ≥ 1246 W or KC281 with L = 2000 mm, H = 130 mm, T = 310 mm, Dimensioning with control voltage of 7 V PKN = 1336 W ≥ 1246 W

The calculations above are for a dimensioning with dry cooling. If system parameters that result in condensation on the cooling register are intentionally selected during planning, the sensible cooling output needs to be considered in addition to the total cooling output. In this case, the sensible cooling output is the determining factor for performance the cooling load. Technical specifications subject to change.

Dew point table For a correct dry cooling dimensioning without condensation, the flow temperature of the cool water needs to be taken into account. The flow temperature of the cooling water can be taken as the lowest possible surface temperature of fin components. Assuming normal conditions (room air temperature 27 °C, relative humidity 50%), the Air temperature [°C]

dew point will be 15.8 °C. This means that condensation can be expected if the flow temperature of the cool water drops below 15.8 °C. Beneficial drying effects associated with fan operation are not taken into account, since this effect depends largely on the fan speed.

Ascotherm® Further information Planning, assembly and installation instructions

Scope of delivery

Connecting of the trench convector

• External, adjustable and acoustically decoupled height adjustments (pre-installed) • For KRP91, KRN92 and KRN81 aluminium linear grille (on request, delivery can be postponed until the end of the construction phase) • For KC281 and KC481 aluminium roll-up grille (on request, delivery can be postponed until the end of the construction phase) • Plastic elements for acoustic decoupling • Installation cover and edge bar protection (for protection during the construction phase)

• Water connection to the face (as standard) or room sided with openings already provided for pipe entry (on request, other connection arrangements also possible). • Attach fittings and connect convector to pipework. • To prevent entry of screed into the floor pan, seal the provided openings with suitable material. (e. g. plastic plugs from the accessory range) • Perform a pressure test. • Cover the convector with the supplied installation cover for protection • When components from other manufacturers are used (e.g. connection set, actuator,…) that are not in the accessory range for the Ascotherm eco, pay attention to the installation dimensions.

Planning advices • To compensate for cold air that occurs on large window areas, the trench convectors must be dimensioned to extend along the entire length of the window. • The thermal behaviour of screeds and floors can compress the floor pans of trench convectors. To prevent this, expansion joints must be provided. • When electrical cables or a thermostatic sensor head with a remote sensor will be used, it is necessary to install an empty conduit. • The installation cover supplied serves to protect the convector during the construction phase and should be replaced with the supplied linear grille or roll-up grille only after all construction work has been completed. The installation cover has only limited loading capability and is not suitable for use as a surface to support scaffolds, ladders etc. • The convector must be accessible for maintenance work at any time.

Installation instructions Positioning and arrangement

The Ascotherm KRN81, KC281 and KC481 are intended exclusively for use in indoor areas (e.g. conservatories, residential and commercial areas, showrooms, etc. The Ascotherm KRN81, KC281 and KC481 cannot be used in swimming pools, damp locations and outdoor areas. In case of doubt, always consult the manufacturer. Any other or additional use shall be considered as improper use. Safety instructions • Electrical work may be carried out only by authorised electricians. Connection must comply with valid VDE regulations and the EVU directives. • When installing Ascotherm KRN81, KC281 and KC481, a suitable residual current-operated protective device (RCD) / earth leakage circuit breaker (less than or equal to 30 mA) must be installed. • In case of failure to comply with the regulations and directives malfunctions with consequential damage and endangerment of individuals can occur. Mixing up wires or connecting improperly can result in MORTAL DANGER! • Note additional safety information in the installation instructions.

Further information

• Remove the packaging film and packaging cardboard from the trench convector before installation. If the top grille has already been delivered, store it in a safe location until construction work has been completed. • Place the trench convector in position and use the external height adjustments to align it. The height adjustments can be placed in the correct position with the aid of a screwdriver. • Use the mounting brackets to secure the floor pan to the floor. • If necessary, use insulation underneath and on the sides of the floor pan as well. • Note the acoustic decoupling
