Abstract

The invention discloses a parallel-connection compressor oil way system and a refrigerating unit. The parallel-connection compressor oil way system comprises a first compressor, a second compressor, a first oil separator connected with the first compressor, a second oil separator connected with the second compressor, and a gas-liquid separator connected with the first oil separator to receive lubricating oil separated from the first oil separator. The gas-liquid separator is connected with the first compressor through a first gas suction pipe and connected with the second compressor through a second gas suction pipe, the oil sucking position of the first gas suction pipe in the gas-liquid separator is not lower than the oil sucking position of the second gas suction pipe in the gas-liquid separator, and the second oil separator is connected with the first gas suction pipe. According to the parallel-connection compressor oil way system, the first compressor and the second compressor can obtain enough lubricating oil and can stably work.

Description

technical field [0001] The invention relates to the technical field of compressor oil circuit systems, in particular to a parallel compressor oil circuit system and a refrigeration unit. Background technique [0002] Parallel compressor oil circuit system in the prior art such as figure 1 As shown, it includes a first compressor 1 , a second compressor 2 , an oil return capillary 3 , a copper filter 4 , an oil separator 5 , a one-way valve 6 and a gas-liquid separator 7 . The exhaust pipes of the first compressor 1 and the second compressor 2 are respectively connected to the inlets of the oil separator 5, and the refrigerant gas with lubricating oil is sent into the oil separator 5 to separate the lubricating oil. Then the refrigerant gas from both sides leaves the oil separator 5 and flows into the exhaust main pipe through the one-way valve 6. The separated lubricating oil is discharged from the oil separator 5, enters the gas-liquid separator 7 through the copper filte...
