摘　　要：为了保护大气臭氧层,将在不远的将来禁止使用CFC12。混合工质是CFC12的替代物之一。由于混合工质的热物理性质与CFC12不同,应用混合工质后必须调整制冷系统。本文提出了调整的法则。用这一法则重新设计或重新选择了冰箱BC—132中的压缩机、冷凝器及其它一些零件,取得了良好的结果。In order to protect the ozonosphere in the atmosphere, utilization of CFC12 will be forbidden in the near future. One kind of CFC12 alternative is refrigerant mixture. Since the thermophysics properties of mixture are different from CFC12, it is necessary to adjust the refrigerating system after using mixture. In this paper, the adjusting rule has been raised. Compressor, condenser and other parts of refrigerator BC-132 have been redesigned or rechoosen according to above rule. Good results have been obtained.
