HVAC air source heat pump with heat recovery energy saving,cooling,heating, also supply hot water for domestic use.
HVAC 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
