一拖多空调制冷系统的回油及贮油实验研究

The experimental research on lubricating oil cycle and oil inventory on the multi - split air conditioning system

本文实验研究了影响一拖多空调制冷系统的回油量和贮油管段的因素。研究发现高温、高压的气态制冷剂有利于回油,制冷系统的贮油管段在低温、低压、低速的气态区。

Two factors that affect the multi - split air conditioning refrigeration system, lubricating oil flow capacity and oil inventory section, are studied on experimental basis in this paper. The study reveals that high - temperature and high -pressure gaseous refrigerant is in favor of lubricating oil cycle,and the oil inventory on the refrigeration system occurs at the tow-temperature and low-pressure gaseous duct section.
