自从引进压缩机以来，暖通空调行业不得不应对制冷系统中的油。已经设计了一些方法来管理油，并将由于油的存在而造成的性能损失降至最低，使用油分离器清除系统中的油是主要的控制方法。本文探讨了机油和机油管理系统在压缩机中的使用。引文:研讨会，ASHRAE交易，第81卷，第2部分，马萨诸塞州波士顿

Since the introduction of the compressor the HVAC industry has had to copewith oil in refrigeration systems. Methods have been devised to manage theoil and minimize the loss in performance due to its presence, and eliminationof the oil from the system by use of oil separators is the primary methodof control. This paper explores the use of oil and oil management systems in compressors.
