双压缩机并联多联机回油问题探讨

Discussion on Oil Returns of Hermetic Compressor in Parallel Operation

本文首先总结压缩机并联的常见回油方法,并分析其优缺点,同时针对变频与定频压缩机组成的多联机系统的回油情况进行分析,设计新的回油系统,通过一套多联机系统进行试验测试出其回油规律与特性。

The common method of oil return was summed up, the advantage and disadvantage of the methodswas analyzed, designing the new oil return system. At the same time the oil return condition of multi-connected refrigerating(heat pump)unit which was made up of the frequency conversion and stable frequency compressor was analyzed, the principle and character of was concluded by testing the multi-connected refrigerating(heat pump)unit system.
