PUMP return oil refrigeration unit

摘要

The invention relates to refrigeration, particularly to oil return to the compressor unit or the refrigeration system compressor unit. In accordance with the utility model oil return device in the refrigeration unit comprises a compressor oil sump, provided with a level switch and associated with the suction conduit of the compressor, and an ejector, associated with the compressor discharge duct via a solenoid valve and a compressor suction pipe. Sump discharge conduit connected with the compressor through a solenoid valve and a compressor suction manifold and ejector associated with sump to create pressure in the sump, lower than the suction pipe of the compressor. The utility model provides a more efficient oil return to the compressor of the refrigeration unit. 2 ZP f ly-1-yl.
