(54) Gas heat pump system


(57) The present invention relates to a gas heat pump system which uses a gas engine (122), and more particularly to a gas heat pump system for driving a compressor (121) to realize a refrigerating cycle by using a gas engine (122).
The gas heat pump system includes a refrigerant pipeline, a compressor (121) for compressing refrigerant, a gas engine (122) for driving the compressor (121), a cooling water pipeline (140) provided to cool down the gas engine (122), a chiller (160) having a refrigerant heat exchanger (161) for heat exchange between the refrigerant from the compressor (121) and a fluid, and a high temperature heat exchanger (162) for heat exchange between the fluid having heat exchanged thus and the cooling water.
