VAPOR COMPRESSION REFRIGERATOR WITH DOSED COOLANT FEED Russian patent published in 2012 - IPC F25B1/00 

FIELD: machine building.

SUBSTANCE: proposed refrigerator comprises closed circuit of coolant including compressor, condenser, receiver, 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 condenser inlet while pipeline outlet is fitted inside switching receiver, under coolant level. Second pipeline communicates receiver with low-pressure pipeline via said electromagnetic valve ahead of refrigerator fluid separator. Note here that pipeline outlet is arranged inside switching receiver above liquid coolant wherein heat exchanger of coolant temperature control is located.

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