Outdoor air temperature: -5°C minimum value. -15°C minimum value with condensing control system. +41°C maximum value for unit in full load conditions. +47°C maximum value for unit in partial load conditions. HEAT RECOVERY SYSTEMS: + 30÷48°C Outlet water temperature range value. WARNING All limit and working values showed in the catalogue are referred to nominal conditions with water to the evaporator 12/7°C and R407C refrigerant charge. For different working conditions and/or other refrigerants, please check the limit operating conditions of the specific model with the electronic selection program RCWORLD. All the products manufactured by the RC GROUP, in its manufacturing divisions, RC CONDIZIONATORI, AMP and SIMAIR, are designed and produced with materials and components suitable to be exposed to temperatures of -40÷45°C without any damage to the material structure nor to the components and machines operational characteristics. In case it will be required that the RC GROUP products, for outdoor installations, will grant working continuity with outside temperatures lower than -15°C, a low ambient temperature kit, with features different for each product, is available upon request.

The involved components are the following: - Cooling compressors electric motor - Condenser fans electric motor - Water pump electric motor (if present) The electric data of the components are indicated on relative technical data tables. EXAMPLE: Calculation for UNICO.A.STD. 21.Z.1 unit with PU 1/1 pumping group: MAXIMUM ELECTRIC ABSORPTION - Compressors A 17,0 + - Condenser fans (*) A 3,5 + - Water pump (*) A 1,7 = Maximum electric absorption A 22,2 To obtain the unit electric absorption values with different feeding voltage, please refer to the following coefficients: Feeding voltage 230.3.50 415.3.50 Coefficient 1,73 0,97 IMPORTANT For water pumps and condenser fans, the values of the nominal electric absorption have been assumed to be same as plate current ones. In the normal operation the electric absorption is lower than the plate current. These values depend on the operating conditions of the unit and control of the system.

The heat reclaim exchangers are installed on every gas circuit of the unit in parallel to the main condenser. The ON-OFF heat reclaim system’s operation is subject to the supply demand of cooling capacity. The heat reclaim device is controlled by a probe placed on the water inlet of the heat reclaim exchangers which senses the water temperature coming from the plant and by a temperature differential which can be calibrated on the microprocessor. In the heat reclaim phase, a special valve which is fitted on the delivery pipeline deviates the gas towards the heat reclaim exchanger totally excluding the air cooled main condenser. In case of an anomalous condensing pressure rise which is caused, for example, by the absence of the hot water flow reclaim, the refrigerant gas is deviated on the main air cooled exchanger to guarantee the chilled water supply. If this inconvenience verifies more than three times in a certain time interval, the microprocessor disconnects the heat reclaim system and shows the anomaly by using an alarm on the display; this alarm is also available on voltage free contacts. In the units with a double refrigerant circuits, the heat reclaim hydraulic circuit is in parallel connected and the water temperature probe is already installed. A special anti-freeze heater avoids water freezing in case of a flow absence and/or in the periods of work suspension in winter season. In this series, welded plate heat exchangers in stainless steel AISI 316 are used. It is also possible to remote-control the connection or the disconnection of the total heat reclaim system thanks to the presence of special contacts on the electric box of the unit.

The system is not regulated. In the units with double refrigerant circuit, the heat reclaim hydraulic circuit is in parallel connected. A special antifreeze heater avoids water freezing in case of a flow absence and/or in the periods of work suspension in winter season. Welded plate heat exchangers in stainless steel AISI 316 are used. The heating capacity which is supplied depends on the kind of refrigerant gas which is used and on working temperatures. Desuperheaters can produce hot water up to the maximum temperature of 70÷75°C and according to the working conditions of the unit.

Same characteristics as the cabinet of the chiller, the plenum is supplied with built-in weatherproof noise absorption partitions. Thanks to the particular disposition of the noise absorption partitions, the air pressure drop across the plenum is zero. NOISE LEVEL REDUCTION The RC GROUP catalogues show the chillers noise pressure level on gas/air heat exchanger side. The noise pressure level on fans air discharge is always higher. With the plenum it is possible to reach, on fans air discharge side, a noise pressure level value of -3dB(A) lower than the nominal one (on gas/air heat exchanger side), for all the chillers. The plenum reduces only the noise level on fan air discharge side. No noise level reduction on the other unit sides. Example: Noise level 1m far on gas/air heat exchanger side in free field conditions for chiller UNICO.A.STD.21.Z.1 = 68 dB(A).
