摘　　要：本文介绍了用三元混合工质R152a/R22/R114替代R12在家用电冰箱中的实验研究结果。结果表明在一定的混合配比范围内,三元混合物的压力水平与R12相当。改变三元组分的配比,将引起冰箱降温水准、运行周期和排汽温度的变化。找到最佳配比后有可能替代在电冰箱中广泛使用的R12。An experimental investigation of replacement of R152a/R22/R114 for R12 in domestic refrigerator is reported. The results show that pressure level of refrigerant mixture R152a/R22/R114 in proportion of certain weight concentration is as same as R12. By changing the proportion of the ternary components,a variation of process of lowring temperature for domestic refrigerator,operating cycle and temperature of discharged vapor is occured. After searching optimal proportion of ternary components, the mixture R152a/R22/R114 can substitute the widely used R12 in domestic refrigerator.
