The gas heat pump air conditioner (GHP) uses gas as the fuel to drive the compressor.
As it uses gas engine, there are various characteristics.
xAs the unit does not easily frost, defrosting operations are infrequent even on very cold days, allowing the unit to
provide stable and continuous heating.
xAs the electric power consumption is about 1 kW, this leads to be less received power equipment.
