3 Outstanding Strength Points Units with R410 refrigerant (it will be the real replacement of R22). s near azeotropic mixture it behaves like a homogeneous substance (reduced service problems in case of leakage or re-charge) with negligible temperature glide. Refrigerant with superior thermo-dynamical proprieties compared to R22 and R407C, it allows to have more efficiency or compact and lighter systems and larger operating limits (T ambient = -15 C in heating mode). Bi-flow electronic expansion devices (optional) on all units : superheating value controlled by microprocessor, simple and accessible refrigeration system especially for heat pump versions with reduction of brazing points and then possible leakage. Cooling only QVSL STR model is fitted with microchannel type condensers offering several advantages : Reduction in weight due to 100% aluminium construction : fins, tubes and headers are in aluminium. Optimal heat transfer due to minimized internal diameter of the channels (microchannels) inside the tube profile, and also due to brazed fins. Higher thermal performances thanks to a high efficiency heat transfer, hence a better compactness. Significant reduction of refrigerant charge due to small internal volume. Low air pressure drop thanks to the small height of the microchannel tubes, thus fan power is reduced. Noise reduction due to less air turbulence. V-shape condenser coils ensuring compactness and small foot print. High EER and COP for both fan coil and floor heating applications. 2 acoustic versions : BLN (Base Low Noise) and ELN (Extra Low Noise). Heat recovery option with desuperheater. Large choice of optional hydro kits with or without buffer tank fitted on board of the chiller to perform package solution and plug & play concept. Optional 3-pump kit : energy saving in partial load. Optional electric heaters fitted inside buffer tank to ensure extra heating. For safety purpose when performing service operation, special valves dedicated to R410 are supplied on the refrigerant system. These valves, of 5/16" flare SE type, are mounted on the liquid line and on the gauges manifold of the unit. Specifications General The new QVSL/ STR units have been designed to operate with HFC 410 refrigerant. Both compressors and heat exchangers (plate heat exchanger and coils) have been optimized for this refrigerant. ll the units are available either in cooling only or heat pump version. Each unit is fitted with high efficient and advanced technology components : - Hermetic Scroll compressors with high efficiency and low vibration emissions, - Quiet fans located in externally mounted nozzle profile housing generating low sound levels, - Controller using a state-of-the-art microprocessor. The QVSL/ STR units are available in 6 sizes and 3 versions : STD (Standard) version : Designed in accordance with specifications described in the following sections. HT (High Temperature) version : It has same equipment as that of the STD version, except that the units are equipped with special inverter fans, of large diameter, driven by EC (electronic brushless type) motors with integrated electronic inverter, to ensure low energy consumption. HPF (High Pressure Fan) version : It has same equipment as HT units. The HPF version provides external static pressure up to 120 Pa. The STD version can be supplied with 2 acoustic options : Base Low Noise (BLN) : The units are equipped with Star or Delta connected fan motors depending on size. The chillers are not supplied with fan speed controller, but fitted with compressors box to reduce the noise emissions. Extra Low Noise (ELN) : The units are equipped with Star connected fan motors, fitted with a speed controller which allows the units to operate with a very low rpm. The chillers are supplied with compressors box and soundproof jackets on compressors reducing significantly the noise emissions. On the other hand, the HT and HPF versions can be supplied with BLN option only. In addition, all the units can be supplied with heat recovery option : Desuperheater : ll the versions can be supplied with plate type heat exchanger fitted on the compressor discharge line to recover about 20 % of the total heat rejected to the condensers. Cabinet and structure The cabinet and structure are made of heavy gauge galvanized steel. ll galvanized steel components are individually painted by a special painting process before the assembly of the unit. This painting system performs a homogeneous protection to the corrosion. The painting is a polyester powder based type, coloured in RL The units are suitable for outdoor installation, directly on the building roof or at the ground level. Refrigerant circuits ll the units are composed of 2 hermetic scroll compressors mounted in tandem. The refrigerant circuit is equipped with liquid line and discharge line shut-off valves, filter-drier, solenoid valve and mechanical expansion valve. The heat pump units ( STR) are provided with 4-way reversing valve, suction accumulator, liquid receiver, sight glass and check valve. The functional diagram of each circuit is shown in the section "Refrigerant flow diagram". Compressors The compressors are hermetic scroll type fitted with an electronic control device which ensures protection of compressors against : - overheating and overloading, - reversal rotation and phase loss. ll compressors have direct-on-line starting and are mounted on rubber vibration isolators in order to minimize noise and vibration transmission. 3

4 Specifications (continued) Evaporator Evaporator is of a brazed stainless steel plate type heat exchanger. It is insulated with a 19 mm thick closed cell polyethylene foam material and is fitted with a film type electric heater on the external surface to prevent the unit from freezing at a low temperature (down to -18 C) when the unit is off. Condenser coils The condenser coils are made of seamless copper tubes, arranged in staggered rows, mechanically expanded into corrugated aluminum fins. For cooling only model (QVSL STR), the condenser coils are of microchannel type, made of 100% aluminium (fins, tubes and headers) with the exception of pipe couplings which are in copper. They are mounted in V-shape arrangement, allowing the unit to be compact with small foot print. Condenser fans ll acoustic versions (BLN & ELN) are equipped with large diameter, direct drive axial type fans with asynchronous three-phase motors. Fans are fitted with externally mounted nozzle profile housing which generates low sound levels. Fan speed control The airflow is controlled in order to operate at a low ambient temperature. On standard unit equipped with axial fans, the air flow control is : - step type for BLN version without fan speed controls, achieved by switching off some fans of each circuit in function of condensing pressure corrected by external temperature. - stepless type for ELN version, achieved by an electronic fan speed control, supplied as standard, in function of condensing pressure. The pressure actuated stepless type fan speed controller can be supplied as optional on BLN version. It allows the units to operate in cooling mode at ambient temperature down to -18 C. Electrical board The electrical board is located in a metal case protected by a vertically pivoted access door. The metal case has an IP54 protection rating and is complete with grilles for natural air ventilation. Electronic control The units are supplied with the new microprocessor-based electronic control and management system ensuring the following functions : Management of the operation of compressors : a) Power on/off b) nticycle management c) Tandem unloading for high pressure or high compressor pressure ratio (integrated inside the curves of compressor operating limits). Chilled and hot water temperature regulation (control option on inlet water temperature RWT (PID) or outlet water temperature LWT (neutral band type) of the evaporator. Evaporator antifreeze protection. Heat pump defrost control for automatic operation. Management of high and low pressure alarms. Management of external interlocks. Management of the remote control : d) Unit power on/off e) Summary alarm signals Remote signalling, by dry contacts : f) Voltage presence g) Compressors in operation h) Circuit alarm unit Management of the hydro kit : start-up of pump, antifreeze heater of external tank.
