在最初为R12设计的单蒸发器家用冰箱中，研究了制冷剂混合物R22/R152A和纯RC270的性能。计算表明，COP预计会增加，实验证实了这一点。对于制冷剂混合物，R22的分数很重要。关键词:制冷剂，性能系数，冰箱，家用，计算，实验，R22，R152a，环丙烷，R12，比较，混合物，非共沸。引文:研讨会，ASHRAE交易1993，第99卷，pt。1.

The performance of refrigerant mixture R22/R152A and pure RC270 was studied in a single-evaporator domestic refrigerator originally designed for R12. Calculation showed that an increase in COP was to be expected and experiment confirmed that this was the case. For the refrigerant mixture the fraction of R22 was important.KEYWORDS: refrigerants, coefficient of performance, refrigerators, domestic, calculating, experiment, R22, R152a, cyclopropane, R12, comparing, mixtures, non azeotropic.
