Abstract

The invention discloses a compressor assembly and a refrigeration system with the compressor assembly. The compressor assembly comprises two compressors arranged in parallel, an oil balance pipe and a drive device. Each compressor is provided with an oil bath and an oil return opening. The two ends of the oil balance pipe are connected with the oil baths of the two compressors correspondingly. The drive device is connected with the oil balance pipe and each oil return opening. The drive device is arranged to enable lubricating oil in the oil balance pipe to be conveyed to each oil return opening. According to the compressor assembly, the lubricating oil in the compressor at the high oil level of the two compressors can flow into the oil balance pipe under the action of the pressure difference, the lubricating oil entering the oil balance pipe is redistributed to the oil return opening of each compressor under drive of the drive device, and therefore the oil level difference between the compressors can be balanced. The compressor assembly is high in balancing precision and high in balancing efficiency.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a compressor assembly and a refrigeration system with the compressor assembly. Background technique [0002] Compressor parallel technology is more and more widely used in the air conditioning and refrigeration industry. Parallel compressors have the advantages of convenient energy adjustment, convenient maintenance of a single shutdown, and low cost. Lubricating oil is indispensable for the compressor to work. However, due to the difference in displacement between compressors, differences in pipeline design, etc., it may cause a certain compressor to be burned due to lack of lubricating oil, especially the scroll compressor in the low-pressure chamber. [0003] In order to solve the above problems, in the related art, an oil balance pipe is usually installed between the parallel compressors, and the oil balance pipe is connected to the oil pool of the parallel compressor...
