The present invention relates to a gas heat pump system, which comprises: an air conditioning module having a compressor, an outdoor heat exchanger, a main expansion device, an indoor heat exchanger, an auxiliary heat exchanger, and a refrigerant pipe; an engine module having an engine combusting a mixer where fuel and air are mixed and providing power for operation of the compressor; and a control unit controlling the air conditioning module and the engine module. The control unit opens the main expansion device when temperature of the refrigerant discharged from the compressor is at least predetermined temperature during heating operation to control temperature and an overheating degree of the refrigerant discharged from the compressor.

    본 발명은 가스 히트펌프 시스템에 관한 것으로, 압축기, 실외 열교환기, 메인 팽창 장치, 실내 열교환기, 보조 열교환기 및 냉매 배관을 포함하는 공기조화 모듈, 연료와 공기가 혼합된 혼합기를 연소하며 상기 압축기의 운전을 위한 동력을 제공하는 엔진을 포함하는 엔진 모듈 및 상기 공기조화 모듈과 상기 엔진 모듈을 제어하는 제어부를 포함하고, 상기 제어부는 난방 운전 시, 상기 압축기에서 토출되는 냉매의 온도가 소정 온도 이상인 경우에 상기 메인 팽창 장치를 개방하여 압축기에서 토출되는 냉매의 온도 및 과열도를 제어할 수 있다.
