燃气机热泵（gas engine-driven heat pump）是一种节能环保的供热系统。为了研究燃气机热泵的能源利用效率，利用构建的燃气机热泵实验台，通过理论分析和实验测试研究了燃气机转速、冷凝器进水流量、冷凝器进水温度对系统性能[供热总量、制热性能系数（COP）以及一次能源利用率（PER）]的影响规律。结果表明：燃气机热泵系统供热量随着冷凝器进水流量、燃气机转速的增加而增加，随着冷凝器进水温度的提高而减少。COP和PER随着燃气机转速和进水温度的升高而减少，进水流量对系统性能系数的影响较小。回收的余热占燃气机热泵系统总供热量的40%左右，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1.15～1.47之间。

The gas engine-driven heat pump (GEHP) system is an efficient energy saving and environment- friendly heating system which consumes natural gas as fuel in a gas engine. The present work aimed at evaluating the performance of a gas engine-driven heat pump for heating. In order to achieve this objective, a test facility was developed and experiments were performed over a wide range of engine rotary speed (1300—1900 r·min?1). The relationships of engine rotary speed, condenser water inlet temperature, condenser water flow and system performance [heating capacity, system coefficient of performance (COP) and primary energy ratio (PER)] were studied based on theoretical analysis and experimental data. The results showed that the heating capacity of GEHP increased with increasing engine rotary speed and condenser water flow rate, but decreased with the increase of condenser water inlet temperature. The COP and PER of the GEHP decreased with increasing engine rotary speed and condenser water inlet temperature. The effect of the engine rotary speed and condenser water inlet temperature on the system performance was more significant than that of condenser water flow rate. The waste heat recovered from the gas engine accounted for about 40% of the total heating capacity, and the PER of the GEHP was between 1.15—1.47 under experimental condition.
