摘　　要：燃气机热泵（GEHP）是一种节能环保的空调装置。通过理论分析和实验测试研究了燃气机热泵部分负荷制冷性能。结果表明：燃气机热泵系统制冷量随着燃气机转速、蒸发器进水流量和蒸发器进水温度的提高而增加。制冷性能系数（COP）和一次能源利用率（PER）随着燃气机转速的增加而减少，随着蒸发器进水温度和进水流量的增加而增加。在考虑余热回收的情况下，燃气机热泵的一次能源利用率在1．29～1．67之间。The Gas engine - driven heat pump （GEHP） system is a kind of new energy - efficient air conditioning equipment which consumes natural gas as fuel. A test facility was developed and experiments were performed over a wide range of engine rotary speed （ 1300 - 1900 r · min^-1 ）. The relationships among engine rotary speed, primary energy consumption, heat recovery, cooling capacity, system coefficient of performance （COP） and primary energy ratio （PER） were studied based on theoretical analysis and experimental data. The test results show that the cooling capacity of GEHP increases with increasing of the engine rotary speed, evaporator water flow rate and evaporator water temperature. COP and PER of the GEHP decrease with the increasing of the engine rotary speed, but increase with the increasing of the evaporator water inlet temperature and evaporator water flow rate. The PER of the GEHP is between 1.29 - 1.67 under experimental condition.
