【摘要】 本文从理论上对替代R407C、R22的五种候选混合工质的环境性能,循环性能及安全性能进行了分析,并综合考虑推荐ZH1(R32／R125／R161,15／34／51％wt)作为R407C、R22的替代物。并在此基础上将所选的新型混合工质ZHI用在使用R407C的电量热器性能测试台上,不对系统作任何改动, 直接进行充灌进行循环性能实验测试(名义工况),由实验结果分析可知,采用ZHI所运行的压比与压缩机耗功低于R407C, COP、单位容积制冷量及制冷量要优于R407C,排气温度要略高于R407C。可考虑ZH1作为R407C的替代制冷剂直接使用。更多还原

【Abstract】 A ternary non-azeotropic mixture of ZHl(R32/R125/R161,15/34/51%wt) as an alternative refrigerant toR407C,R22 is proposed by analyzing the environmental properties, safety and theoretical cycle performances of the five candiated mixtures containing R161 in this paper. Without any modification to system components, experimental tests using the refrigerant ZH1 are performed on a vapor compression refrigeration set with a reciprocating compressor which was originally designed for R407C. Experimental results under the air-conditioning working condition indicate that the pressure ratio and power consumption are lower than those of R407C,and the cooling capacity and COP are superior to those of R407C respectively, and the discharge temperature is slightly higher than that of R407C. Therefore, the new refrigerant ZH1 could be considered as a promising retrofit refrigerant to R407C.更多还原
