本文从保护大气环境的观点出发,对丙烷系氟里昂作为制冷剂替代物的可能性进行了探讨。推算了部分丙烷系氟里昂的标准沸点、临界温度和临界压力。对筛选出的几种丙烷系氟里昂进行了理想蒸气制冷循环的计算分析,并与氟里昂R12的循环性能进行了比较。
In this paper, from the point of view of protecting atmospheric environment, the possibility of propane-based freon as a refrigerant substitute is discussed. The standard boiling point, critical temperature and critical pressure of some propane series freon were calculated. The calculation and analysis of the ideal vapor refrigeration cycle of several propane flon was carried out and compared with the cycle performance of freon R12.
