新冷媒压缩机用冷冻机油POE与PVE的分析和选用

ANALYSIS AND SELECTION OF LUBRICATING OIL PVE AND POE FOR ALTERNATIVE REFRIGERANT COMPRESSOR

主要介绍和讨论了目前业界主要使用的两种用于新冷媒(本文指R407C或R410A)系统的冷冻机油——PVE和POE的基本性质,并从对压缩机本身和对制冷系统影响两个方面论述了它们之间的一些主要区别。

Introduces the base character of the POE and the PVE,two kinds of lubricating oil used most wildly in the industry of alternatlive refrigerants （R407C and R410A）,and discusses the difference between them based on the impact on the compressor and the whole aircondition system.
