Oil balancing unit of double-compressor air-conditioning

一种双压缩机空调油平衡装置

Abstract

本发明涉及一种双压缩机空调油平衡装置,该装置包括制冷回路上连接的并联第一压缩机和第二压缩机,两台并联压缩机之间连接有一根气平衡管和一根油平衡管,一个油分离器,一个冷凝器,一个电子膨胀阀,一个蒸发器,以及三个电磁阀,其中两台并联压缩机总排气管侧连接油分离器,油分离器的出口管与冷凝器相连,油分离器的回油管与两台并联压缩机的总吸气管相连,冷凝器一端与油分离器出口管连接,一端串联接电子膨胀阀,电子膨胀阀一端接冷凝器,出口端串联接蒸发器,蒸发器一端接电子膨胀阀,一端接两并联压缩机的总吸气管。本发明是能够改善并联双压缩机空调机组油平衡问题的装置,它能确保每台压缩机都能在安全油面以上进行长期运转,两台压缩机之间能建立动态的油平衡状态。
The invention relates to a dual-compressor air-conditioning fuel balancing device, comprising parallel a first compressor and a second compressor connected on a refrigerating circuit, a gas balance tube and an oil balance tube connected between two compressors, an oil separator, a condenser, an electric expanding valve, an evaporator, and three electromagnetic valves. The total discharge tubes of two compressors are connected with the oil separator whose outlet tube is connected with the condenser and reflux tube is connected with a total air inlet tube of the compressors. One end of the condenser is connected with the condenser whose one end is connected with the expanding valve. One end of the expanding valve is connected with the condenser, while the outlet is serially connected with the evaporator whose one end is connected with the expanding valve and another end is connected with the total air inlet tube of the compressors. The invention can assure each compressor works long time at safe oil level, and build dynamic oil balance between compressors.
