摘　　要：对一种ODP(臭氧破坏势)为零的新型环保非共沸混合工质M1,在冷凝温度范围为80~110°C、循环温升为45°C的高温热泵工况下,进行了循环性能的理论和实验研究。理论循环性能分析表明,M1的综合性能优于传统工质CFC114;实验结果表明,M1系统的制热量Q和循环性能系数COP随工况温度的升高而提高。实验中,M1的最高平均冷凝温度达到102.3°C,相应热输出温度为103.0°C,冷凝压力和排气温度分别为1.951 MPa和119.0°C,都在安全应用的限制范围内。A theoretical and experimental study was conducted of the cycle performance of a new type of environmental protection non-priming hybrid working medium M1,which has a zero ozone depleting potential(ODP).Under the operating condition of a high temperature heat pump of which the condensing temperature ranges from 80 to 110 ℃ and the cyclic temperature rise reaches 45 ℃,a theoretical and experimental study was performed of the cycle performance.An analysis of the theoretical cyclic performance shows that the c...
