Abstract:

燃气机热泵(gasengine-drivenheatpump)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。
