一、引言制冷压缩机运行时,会有一定数量的润滑油被制冷剂带入制冷系统内。整个制冷系统的管道、设备都应能便于这种冷冻用润滑油在系统中循环,以确保油能回流至压缩机的油箱。本文将着重研究气体制冷剂和油同时出现的一些敏感区域,并将重点讨论管道系统和管道式热交换器。二、制冷系统中的油可确保油循环的常用方法有下列几种:
First, the introduction Refrigeration compressor operation, there will be a certain amount of oil is refrigerant into the refrigeration system. The entire cooling system piping, equipment should be able to facilitate the circulation of refrigeration oil in the system to ensure that the oil can be returned to the compressor tank. This article will focus on the simultaneous appearance of gas refrigerant and oil in some sensitive areas, and will focus on pipe systems and pipe heat exchangers. Second, the refrigeration system of oil to ensure that the oil circulation commonly used methods are the following:
