Air cooled screw chillers McQuay Energyplus B McQuay International introduces Energyplus B air cooled screw chillers equipped with single screw compressors in cooling capacity range 363 kW – 624 kW. McQuay air cooled Energyplus B are equipped with McQuay Frame 3200 single screw compressors. They are manufactured by McQuay to satisfy the requirements of the consultants and the end user. McQuay Energyplus B units are designed to minimise energy costs while maximising the refrigeration capacities. Once again McQuay has developed a line of chillers unsurpassed in performance and quality that will meet the most stringent requirements of comfort cooling, ice storage and process applications. McQuay’s chiller design experience, combined with outstanding features makes the Energyplus B chiller unmatched in the industry.

Lower noise – higher flexibility The McQuay original compressor design with a single screw and twin rotors allows a constant gas flow. This compression process completely eliminates gas pulsations. The twin gas compressor discharge chambers are designed to act as attenuators, based on the harmonic wave principle with destructive interference, thus always resulting almost equal to zero. The extremely low noise compressor performance allows the use of Energyplus B chiller for all applications. The reduced level of vibrations produced from the Energyplus B chillers offers a surprisingly quiet operation eliminating the noise transmission through the structure and the chilled water piping system.

Code requirements All Energyplus B units are designed and manufactured in accordance with applicable selections of the following which are equivalent to American Air-conditioning industry applicable codes: Rating of chillers: EN 12055. Construction of pressure vessel: TUV Standards (on request). Electrical codes: IEC 204-1 CEI 44-5 Elect. & Safety Codes Safety Codes: CEI-EN 60204–1 Codes. Manufacturing Quality Stds: ISO 9001:2000.

Infinitely variable capacity control Cooling capacity control is infinitely variable by means of a capacity slide controlled by microprocessor system. Each unit has infinitely variable capacity control from 100% to 12.5%. This modulation allows the compressor capacity to exactly match the building cooling load. The result is a decrease in chiller energy costs, particularly at the part-load conditions at which the chiller operates most of the time. Additionally, in some case there should be the possibility to avoid inertial tank in the water circuit.

Unmatched serviceability Field serviceability has not been sacrificed. Inspection covers allows visual inspection of the main screw and gaterotors.

Outstanding reliability features Full factory testing of all the units ensures a trouble free start-up. Extensive test makes certain that each safety and operating control is properly adjusted, and operates correctly.

General characteristics Cabinet and structure The cabinet of Energyplus B units is made of galvanized steel sheet and painted to provide a high resistance to corrosion. The unit base frame has holes to lift the unit with ropes for an easy installation. The weight is uniformly distribuited along the profiles of the base and this facilitates the arrangement of the unit.

Screw compressors with integrated oil separator

The StargateTM single-screw compressor (Frame 3200) has a well balanced compression mechanism which cancels the screw rotor load in both the radial and axial directions. Inherent to the basic single-screw compressor design is the virtually load-free operation, that gives main bearing design life of 3-4 times greater than twin-screws, and eliminates expensive and complicated thrust balancing schemes. The two exactly opposed gaterotors create two exactly opposed compression cycles. Compression is made at the lower and upper parts of the screw rotor at the same time, thus cancelling the radial loads. Moreover both ends of the screw rotor are subjected to suction pressure only, which cancels the axial loads and eliminates the huge thrust loads inherent in twin-screw compressors. Compressors are provided with an integrated high efficiency oil separator to maximise oil separation. Compressors have an infinitely variable capacity control down to 25% of its total capacity. This control is made by means of capacity slides controlled by microprocessors. Standard start is star-delta type; Soft start type is available (as option) in order to have lower inrush current.

Ecological HFC 134a refrigerant

McQuay has designed and optimized StargateTM compressors to operate with HFC 134a, ecological refrigerant with zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming Potential) that means low TEWI (Total Equivalent Warming Impact).

Evaporator The units is supplied with optimised counter-flow evaporator single refrigerant pass. It is direct expansion with refrigerant inside the tubes and water outside (shell side) with carbon steel tube sheets, with straight copper tubes that are spirally wound internally for higher efficiencies, expanded on the tube plates. The external shell, is linked with an electrical heater to prevent freezing down to -28 °C ambient temperature, commanded by a thermostat and is covered with a closed cell insulation material. Each evaporator have 2 refrigerant circuits one for each compressor. Each evaporator is manufactured in accordance to PED approval.

509 B – 06/04 C – pag. 4/40


Condenser coils The Energyplus B units are constructed with internally enhanced seamless copper tubes arranged in a staggered row pattern and mechanically expanded into McQuay lanced and rippled aluminium condenser fins with full fin collars. An integral subcooler circuit provides sub-cooling to effectively eliminate liquid flashing and increases in cooling capacity without increasing the power input.

Condenser coil fans The condenser fans are helical type with wing-profile blades to achieve a better performance. The direct coupling with the electrical motor eliminates any problems with regard to the application of transmission devices reducing vibrations caused by the functioning. The three-phase type motors are supplied as standard with IP54 protection (Insulation class F); they are protected against overloading and short circuits by circuit breakers located inside the electrical control panel. With this chiller line (McPower with HFC 407C ) McQuay International starts to use a different fan shape (see image on the right). The fans, with their blades, are installed immediately at the top of the condenser coils in a circular metal baseframe with metal grill. This allows noise reduction on the top side of the chiller and a better performance of the highest condenser tube rows for a consequent higher air velocity. The chiller height doesn’t change thanks to an improved condenser coil design.

Expansion device Energyplus B is equiped with a thermostatic expansion valve. Electronic expansion device (EEXV) will be available as option.

Electrical control panel Power and control are located into two sections of the main panel that is manufactured to insure protection for all weather conditions. The power panel is fitted with an interlocked door main isolator to prevent access while power supply is on. Electrical panel is IP54. Power section includes - The power section includes contactors, all compressors fuses, fans circuit breaker (magneto-thermal), and control circuit transformer. Additional space is provided for an easy installation of the various optional accessories provided to enhance the Energyplus B units capabilities.

Intelligent Compressor Start Mode Control software includes an intelligent compressor start mode that is unloading the first compressor to 75% during the start of compressor n° 2, in order to reduce inrush current.

Certifications All the Energyplus B units are CE marked (89/392). McQuay Italia obtained ISO 9001:2000 certification.

509B – 06/04 C– pag. 5/40


Water content in cooling circuits The cooled water distribution circuits should have minimum water content to avoid excessive compressors start and stop. In fact, each time the compressor starts up, an excessive quantity of oil goes from the compressor sump and simultaneously there is a rise in the temperature of the compressor motor’s stator due to the inrush current during the start-up. To prevent damage to the compressors, McQuay has envisaged the application of a device to limit frequent stops and restarts. During the span of one hour there will be no more than 6 starts of the compressor. The plant side should therefore ensure that the overall water content allows a more constant functioning of the unit and consequently greater environmental comfort. The minimum water content per unit should be calculated with a certain approximation using this simplified formula: (1)

Q = 35,83 X

P (kW) ∆T(°C)

where: Q = minimum water content per unit expressed in litres P = minimum cooling capacity of the unit expressed in kW ∆T = evaporator entering / leaving water temperature difference expressed in °C For more accurate determination of quantity of water, it is advisable to contact the designer of the plant.

MicroTech II C Plus controller MicroTech II C Plus controller is installed as standard on all the units; it can be used to modify unit set points and check control parameters. A display illustrates the machine' s operating status, programable values and setpoints e.g. temperatures, and pressures of fluids (water, refrigerant and air). Device controls maximise the McQuay chillers energy efficiency and reliability characteristics. It uses sophisticated software with predictive logic to select the most energy efficient combination of compressor, EEXV and condenser fan to keep stable operating conditions and maximise energy efficiency. The compressors are automatically rotated to ensure equal operating hours. MicroTech II protects critical components in response to external signals from its system sensors measuring: motor temperatures, refrigerant gas and oil pressures, correct phase sequence and evaporator.

Installation notes Handling Care should be taken to avoid rough handling or shock due to dropping the unit. Do not push or pull the unit from anything other than the base, and block the pushing vehicle away from the unit to prevent damage to the cabinet. Never allow the unit fall during unloading or moving as this may result in serious damage. To lift the unit, holes are provided in the base of the unit. Spreader bar and cables should be arranged to prevent damage to the condenser coil or unit cabinet.

Location The Energyplus B units are produced for outside installation on roofs, floors or below ground level on condition that the area is free from obstacles for the passage of the condenser air. The unit should be positioned on solid foundations and perfectly level; in the case of installation on roofs or floors, it may be advisable to arrange the use of suitable weight distribution beams. When the units are installed on the ground, a concrete base at least 250 mm wider and longer than the unit’s footprint should be laid. Furthermore, this base should withstand the unit weight mentioned in the technical data table. When the units are positioned in areas which are easily accessible by persons or animals, it is advisable to fit guards to protect the condenser coil guards and, when necessary, also guards to protect the evaporator area.

Space requirements The Energyplus B units are air-cooled, hence it is important to observe the minimum distances which guarantee the best ventilation of the condenser coils. Limitations of space reducing the air flow could cause significant reductions in cooling capacity and an increase in electricity consumption. To determinate unit placement, careful consideration must be given to assure a sufficient air flow across the condenser heat transfer surface. Two conditions must be avoided to achieve the best performance: warm air recirculation and coil starvation.

509B – 06/04 C– pag. 9/40


Both these conditions cause an increase of condensing pressures that results in reductions in unit efficiency and capacity. The Energyplus B chiller performance is less affected in poor air flow situations because of its special condensing coil geometry. Moreover McQuay’s unique microprocessor has the ability to calculate the operating environment of the chiller and the capacity to optimize its performance staying on-line during abnormal conditions. Each side of the unit must be accessible after installation for periodic service. Fig.1 shows you minimum recommended clearance requirements. Vertical condenser air discharge must be unobstructed because the unit would have its capacity and efficiency significantly reduced. If the units are positioned in places surrounded by walls or obstacles of the same height as the units, the units should be at least 2500 mm from obstacles (fig.2). In the event the obstacles are higher than the units, the units should be at least 3000 mm from the obstacle (fig.4). Units installed closer than the minimun recommended distance to a wall or other vertical riser may experience a combination of coil starvation and warm air recirculation, thus causing reduction in unit capacity and efficienty reductions. Once again, the microprocessor will allow the chiller to stay on line, producing the maximum available capacity, even at less than recommended lateral clearances. When two or more units are positioned side by side it is recommended that the condenser coils are at least 3600 mm distance from one another (fig.3); stong wind could be the cause of air warm recirculation. For other installation solutions, consult McQuay technicians.

Acoustic protection The low noise levels of the Energyplus B units means that they meet the most restrictive regulations, thanks to the availability of four versions with different sound levels. When the noise level must meet special requirements it will be necessary to pay the maximum attention to ensure the perfect insulation of the unit from the support base by applying appropriate vibration-dampening devices, applying vibration-dampening mounts on the water pipes and on the electrical connections.

CHILLER COMPONENTS Compressors The compressors shall be field serviceable, semi-hermetic, single-screw type with one main helical rotor meshing with two opposed gaterotor. If a twin-screw compressor is used, the manufacturer shall provide an external 5-year part and labor warranty covering all moving parts due to the large bearing load inherent with this design. The two exactly opposed gaterotors create two exactly opposed compression cycles which results in balanced forces acting on the compressor. The gaterotors will be constructed of a carbon impregnated engineered composite material. The gaterotor supports will be constructed of cast iron. The oil injection shall be used for these compressors in order to get high COP also at high condensing pressure and low sound pressure levels in each load condition.

The compressor shall be provided with an automatic spring return of capacity control valve to the minimum load position to ensure compressor starting always at minimum motor load. Evaporator The units shall be supplied with shell and tubes counter-flow evaporator single refrigerant pass. It will be direct expansion with refrigerant inside the tubes and water outside (shell side) with carbon steel tube sheets, with straight copper tubes that are spirally wound internally for higher efficiencies, expanded on the tube plates. The external shell, shall be linked with an electrical heater to prevent freezing to -28 C ambient temperature, commanded by a thermostat and shall be insulated with flexible, closed cell polyurethane insulation material. The evaporator will have 2 circuits, one for each compressor and shall be single refrigerant pass. If a plate to plate heat exchanger is used, the manufacturer shall provide to furniture an adequate buffer tank to avoid frequently compressors star-stop and to allow a good evaporator leaving water temperature control. The manufacturer also shall provide to furniture a feed water line filter, a monitoring system of the refrigerant pressure drop inside the plat to plate heat exchanger and a system to protect the component from hydraulic pressure waves caused by water circulation pump stop. Evaporator is manufactured in accordance to PED approval. Condenser coil The condenser coils are constructed with internally enchanced seamless copper tubes having a "W" configuration and arranged in a staggered row pattern and mechanically expanded into lanced and rippled aluminium fins with full fin collars for higher efficiencies. The space between the fins are given by a collar that will increase the surface area in connection with the tubes, protecting them from ambient corrosion. The coils will have an integral subcooler circuit which provides sufficient subcooling to effectively eliminate the possibility of liquid flashing and increase the unit' s efficiency of 5-7% without an increase in power absorbed, and the surface area will be designed in order to have an air velocity not higher than 2.8 m/sec. Condenser fans The fans used in conjunction with the condenser coils, shall be helical type with aerofoil blades for higher efficiencies and lower noise.
