The invention provides a mixed environment-friendly refrigerant, a refrigerating device and application. The mixed environment-friendly refrigerant comprises the following components in percentage by weight: 38-98% of propane, 1-28% of trifluoromethyl methyl ether and 1-40% of propylene. The ODP value of the mixed environment-friendly refrigeration working medium is 0, the GWP value is low, the cycle performance is good, the working pressure is close to that of R134a, the mixed environment-friendly refrigeration working medium can be directly used on the premise that main devices are not changed, the problem that an existing R134a refrigerant is high in GWP value is solved, and the mixed environment-friendly refrigeration working medium can serve as a long-term replacement working medium of R134a to be applied to an air conditioner refrigeration system.
本发明提供了一种混合环保制冷工质、制冷装置及应用。按重量百分含量计,混合环保制冷工质包括:38~98%丙烷,1~28%三氟甲基甲基醚和1~40%丙烯。本申请提供的混合环保制冷工质的ODP值为0、GWP值低、循环性能好、工作压力与R134a相近,在不改变主要器件的前提下可直接使用,以解决现有R134a制冷剂存在GWP值较高的问题,可作为R134a的长期替代工质应用于空调制冷系统。
