摘　　要：由于现在使用的HFCs制冷剂GWP较高,不符合当前对制冷剂环保性的要求,寻找新型替代制冷剂已迫在眉睫。R290/R600a作为新型环保制冷剂逐渐被人们关注,本文主要概述了混合制冷剂R290/R600a的热物性及制冷研究现状,并与目前常用的R134a进行分析比较,表明了R290/R600a具有替代R134a的潜力。The Global Warming Potential (GWP) of hydrofluorocarbons (HFCs) is usually higher, which can’t meet the current requirements of the refrigerant environmental protection, so finding new alter-native refrigerant is imminent. As the new type of refrigerant, R290/R600a is gradually being concerned. In this paper, the thermal physical properties of the new type of environmentally friendly refrigerant mixture R290/R600a and its refrigeration properties were summarized. It was also compared with the commonly used refrigerant R134a, and it revealed that R290/R600a had the potential to replace R134a.
