ABSTRACT:
There is provided a multiform gas heat pump type of air conditioning system having: a plurality of indoor units that are each provided with an indoor heat exchanger and that perform a heat exchange between air inside a room and refrigerant; an outdoor unit provided with a compressor driven by a gas engine and an outdoor heat exchanger for performing a heat exchange between outside air and the refrigerant; and a split flow control unit for controlling a flow direction of the refrigerant in each of the indoor units and for performing a selection switching between cooling and heating operations. The outdoor heat exchanger that switches selection between cooling and heating operations is divided into a plurality of units that are connected in parallel and there is also provided a refrigerant supply switching means that controls the refrigerant flow in each of the divided portions of the outdoor heat exchanger.
