CIRCUIT WITH DOUBLE-STAGE THROTTLING BY CAPILLARY TUBES AND WITH RECEIVER Russian patent published in 2009 - IPC F25B1/00 F25B40/00 F25B41/06 

FIELD: heating; refrigerating or freezing plants.

SUBSTANCE: closed refrigerating circuit comprises compressor (1), condenser (2), evaporator (4), receiver (9), capillary tube (8) between condenser and receiver, capillary tube (10) between receiver and evaporator and thermal contact (11) between suction pipeline and receiver. Suction pipeline is oriented so that sucked gas passes through receiver from its lower part to upper part. Cooling agent in receiver flows from its upper part to lower part. There is thermal contact (12) between suction pipeline and capillary tube (8), which connects condenser and receiver.

EFFECT: superheating of sucked gas, prevention of water condensation in suction pipeline and increased efficiency factor.
