VRF (variable refrigerant flow) systems are normally powered by electricdriven compressors with an INVERTER for variable speed control.

The GHP is a VRF system, which has the compressor powered byan engine using natural gas as the input fuel.

This means that large cooling / heating systems can be installed inbuildings which have a limited electricity supply. The GHP requiressome electrical power for the fans and controls, but this is minimalcompared to the power requirements of a conventional VRF, Chiller,or other type of system.

In winter, the heating performance is maintained in very cold ambientconditions, because the waste heat from the engine is utilised asa secondary heat source to enhance the output of the heat pump.
