摘要
燃气热泵空调(GEHP)是一种节能环保的空调装置。通过理论分析和实验测试对燃气热泵空调系统进行性能评价。实测结果表明:夏季空调的实际运行负荷为机组负荷的50%时运行的时间最长,冬季热泵负荷为机组30%负荷时,运行时间最长。当蒸发器进水流量和温度不变时,提高燃气机转速的提高,系统的制冷/制热量逐渐增加,而系统的COP和PER逐渐降低。
Gas engine heat pump （GEHP） is a kind of energy saving and environmental protection air conditioning device. The performance evaluation of GEHP was carried out by theoretical analysis and experimental test. The measured results show that actual operating load that 50% of rated load running time is longest in summer and 30% load in winter. When the inlet flow rate and temperature of the evaporator is constant, with the increase of the engine speed, the cooling capacity of the system increases, while the COP and PER of the system decrease.
