一、概述制冷系统在实际运行中往往会产生制冷性能下降的情况。除机械磨损等因素外,其中一个重要原因是冷冻油对整个制冷系统的影响。据有关研究,由此造成的系统性能下降可达10%以上,可见这是一个不可忽视的影响。国外学者很早就开始对这个问题进行研究,Bambach,G.在1955年完成了R 12—烷烃类油的溶解度方程的关联,该方程已被很多研究者所验证和引用。K.W.Cooper利 First, an overview Refrigeration system in the actual operation will often have a cooling performance decline. In addition to mechanical wear and other factors, one of the important reasons is the impact of refrigeration oil on the entire refrigeration system. According to the research, the resulting system performance decline of up to 10% or more, we can see that this is a can not be ignored. Foreign scholars have long been on the issue of research, Bambach, G. in 1955 completed the R 12-alkane oil solubility equation of correlation, the equation has been validated and cited by many researchers.
