air source heat pump with heat recovery Model: HRCF/RH series Cooling Capacity 5.5kw-30kw Heating Capacity 6.2kw-34kw Heat recovery 1.4-7.6kw Refrigerant: R407C,R410A,R290 Compared with traditional chillers, the air source heat pump with heat recovery can provide hot living water on the basis of heating/cooling, the desuperheaters make use of the hot refrigerant vapor leaving the compressor to heat the water through a relatively small liquid to refrigerant heat exchanger without increasing the power consumption of the compressor. The dusuperheater can transfer 25 to 30 percent of the energy that would otherwise be dissipated by the condenser. STRUCTURE Panels and base frame are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents. HERMETIC COMPRESSORS Single phase rotary type (mod. 5 only) and 3-phase scroll compressor (mod.8.5-30), with thermal overload cut-out and crankcase heater mounted on rubber vibration isolators. AXIAL FANS External rotor type axial fans, equipped with single phase direct drive motors, low noise 6 poles, protection level IP54, provided with a protective outlet grille. EVAPORATOR High efficiency tube in tube type, factory insulated with flexible close cell material. CONDENSER Coils are consisting of seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins, protected with flexible plastic grill. DESUPERHEATER High efficiency stainless steel brazed plate heat exchanger, factory insulated with flexible close cell material. REFRIGERANT CIRCUIT Copper tube connection with charge valve, filter, sight glass, gas-liquid separator, thermostatic expansion valve, low pressure switch with automatic reset, high pressure switch with manual reset. The heat pump unit is completed also with 4-way valve, liquid receiver and one way valve. HYDRONIC CIRCUIT Built with air vent valve, water drain connection, and female-threaded hydraulic connectors. ELECTRIC PANEL consists of: Compressor contactor; Compressor protection breaker; Fan motor protection breaker; Control circuit protection breaker; Phase sequence relay (only for 3-phase power supplied units); Programmable microprocessor controller OPTIONAL Additional electric heater embedded in the coils for defrosting in low temperature ambient. It must be factory installed.
