摘　　要：通过建立理想VM循环燃气热泵的理论模型,分析了热泵运行的温度区间对系统性能系数的影响。分析发现理想VM循环燃气热泵的性能系数只与高温热源、低温热源和中间温度热源的温度有关,而与工质的性质无关。其中低温热源温度的变化对性能系数的影响最大,中间温度热源次之,高温热源温度变化的影响最小。According to build the academic model of the ideal VM circulation fuel gas heat pump, the impacts of heat pump＇s temperature operation area on the ideal VM circulation fuel gas heat pump＇s coefficient of performance was analyzed, which only depends on the temperature of the heater, radiator system and cooling system. It has no relation with the working fluid. And the temperature of the cooling system has the biggest influence on the coefficient of performance, then the temperature of the radiator system, and the temperature of the heater has the least influence.
