VRF Air Conditioning Systems - Hot Water Recovery

Hot Water Recovery Standard VRF GHP Outdoor Unit

The Yanmar ENCP850J- ( )H unit is an 85kW VRF GHP air conditioning unit that recovers heat from the gas engine in the unit to provide up to 30kW of hot water.

In addition to the benefits offered by other VRF GHP units, the hot water recovery GHP system also provides:

  • VRF air conditioning PLUS hot water output all year round
  • Greater financial savings by providing 'free' hot water
  • Greater levels of comfort with reduced energy usage

The hot water recovery GHP unit uses an additional heat exchanger to recover heat energy from the engine. By making a suitable connection to the unit it can provide hot water for showers etc.
