【Abstract】 The alternative refrigerants of R22 such as R407C、R410A, which have been studied much and deeply, still do a little harm to the environment. In this paper, some refrigerants with less harm to the environment are introduced, whose physical and chemical property is also discussed, as well as their performance in refrigeration or heat pump cycle.更多还原
