Abstract

The invention relates to an oil separator, an oil return system and a refrigerating system. The oil separator comprises a cylinder, a basic oil return opening formed in the lower part of the cylinder, at least one enhanced oil return opening, and at least one oil level switch; each enhanced oil return opening and the basic oil return opening are spaced from each other on the cylinder; and each oil level switch is arranged on the side wall of the cylinder, each oil level switch corresponds to one enhanced oil return opening, and the corresponding oil level height in the cylinder is monitored, and each enhanced oil return opening is lower than any one of the at least one oil level switch in the height direction of the cylinder. According to the oil separator, oil can be returned in time, and the oil return efficiency is remarkably improved. The invention further discloses the oil return system and the refrigerating system comprising the oil separator.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to an oil separator, an oil return system and a refrigeration system. Background technique [0002] A refrigeration system usually includes four basic components, a compressor, a condenser, a throttling mechanism, and an evaporator, which can form a circuit that allows the refrigerant to circulate in it, and the compressor is used to compress the low-temperature and low-pressure gas refrigerant into a high-temperature and high-pressure one. gas refrigerant. Compressors, such as scroll compressors, centrifugal compressors, screw compressors, etc., often require lubricating oil to lubricate and seal their moving parts during work. Therefore, when the compressed high-temperature and high-pressure gas refrigerant in the compressor is discharged from the compressor very quickly, the lubricating oil in the compressor easily forms oil vapor and oil droplet particles and is discharged together wit...
