摘　　要：针对现有R22替代工质所存在的问题,本文提出用环保性能好、饱和蒸气压接近R22的天然工质丙烯(R1270)作为R22的新型替代工质,通过对R1270、R22和R290的热物理性质和热力学循环性能的分析、比较,发现R1270替代R22可以在一定程度上改善系统的运行特性,并比R22的现有替代工质R290更具有优势。To solve the problems existing in present substitutes for R22, propylene that is environmental friendly and the saturation vapor pressure curve is close to R22 is put forward as a new substitute for R22 in this paper. After analyzing and comparing the thermohysical performance and thermal cycle performance of R1270, R22 and R290, it is found that R1270 can improve the running performance of system and has more advantages than R290 as substitute for R22.
