VAPOR COMPRESSION REFRIGERATOR WITH COOLANT DOZED FEED AND COMPRESSOR PROTECTION AGAINST MOIST STROKE Russian patent published in 2012 - IPC F25B1/00 

FIELD: machine building.

SUBSTANCE: proposed refrigerator comprises closed circuit of coolant including compressor, condenser, fluid separator, evaporator and system to feed coolant into evaporator. Receiver represents closed-circuit switching receiver of dosed filling correction arranged outside refrigerator work area. Said receiver is communicated via pipeline and electromagnetic valve with coolant preset temperature difference system with refrigerator high-pressure pipeline ahead of its inlet in condenser. Second pipeline communicates receiver with low-pressure pipeline via said electromagnetic valve ahead of refrigerator fluid separator. Coolant heat-control heat exchanger is arranged inside switching receiver. Ejector of coolant draining from fluid separator is arranged on high-pressure pipeline, between throttle valve and evaporator inlet. Said ejector communicates via electromagnetic valve with fluid separator.

EFFECT: decreased weight and overall dimensions, simplified supply, higher safety.
