摘　　要：本文通过建立循环分析模型,研究了燃气机热泵用于高温供热的性能。计算结果表明,在高供回水温度的应用场景中,燃气机热泵具备显著的节能优势。当供回水温度为90℃/50℃时,燃气机热泵的一次能源利用率(PER)较CO_(2)热泵和喷气增焓R134a热泵分别提升了16%和9%。此外,燃气机热泵在低温工况下也能稳健高效运行,环境温度为-10℃时,其一次能源利用率较CO_(2)热泵和喷气增焓R134a热泵可分别提升17%和18%。The performance of gas engine driven heat pump(GHP)for high temperature heating by developing cycle analysis models is analyzed in this paper.The results show that GHP is more suitable for applications with high supply and return water temperatures.When the supply and return water temperature is 90℃ and 50℃,the primary energy ratio(PER)of GHP is 16% and 9% higher than that of CO_(2) heat pump and enhanced vapor injection(EVI)heat pump,respectively.In addition,the GHP can also operate stably at low ambient temperature,and PER at -10℃ is 17% and 18% higher than that of CO_(2) heat pump and EVI heat pump,respectively.
