摘要/Abstract

摘要：

首先自主设计搭建溶油性测试系统，测试获得新型PVE油与R32的两相分离温度曲线，分析其互溶性，接着将R32与POE，R32与PVE两种组合使用至某型号热泵分体式空调，对比研究了R32与新型PVE油配合使用对空调性能的影响。结果表明，在测试含油率范围内，R32与R410A专用POE油的互溶性不理想，分离温度高于R410A与POE组合，而PVE油与R32的互溶性有较大改善，最低分离温度可比R410A与POE低8.4℃；空调性能影响方面，R32配合PVE的使用可降低配合POE使用时排气温度约2.6℃，在制冷量和COP方面也具优势。

Abstract:

The oil soluble test system was built to get the two phase separation temperature curve of new PVE oil and R32. The mutual solubility of new PVE oil and R32 was analyzed. Then the air conditioning performance of a heat pump split air conditioner was tested at two conditions, one is charging R32 combined with POE oil and the other is charging R32 combined with PVE oil. The results showed that the mutual solubility of R32 and POE oil was not ideal in the test range of oil content. The two phase separation temperature at condition of charging R32 combined with POE oil was higher than that of R410A and POE. The mutual solubility of PVE oil and R32 was better. The minimum separation temperature was 8.4℃ which is lower than that of R410A and POE. In the aspect of the effect on air conditioner performance, the exhaust temperature in case of using PVE oil was 2.6℃ which is lower than that of using POE oil. It also had improvement on cooling capacity and COP by using PVE oil.

Key words: solubility, experiment validation, PVE oil, two phase separation temperature, COP
