Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2019/156021
Kind Code:
A1
Abstract:
This refrigerator has: a refrigeration cycle comprising a compressor, a first condenser, a second condenser, an evaporator, and a flow path switching device; a storage compartment; a cold-storage device; and a control device. On the downstream side of the first condenser the refrigeration cycle branches into a cooling passage and a defrosting passage. The control device switches the flow path of a refrigerant between the cooling passage and the defrosting passage. In the cooling passage the refrigerant passes through the second condenser and then is supplied to the evaporator. The refrigerant flowing in the defrosting passage is heated by exchanging heat with a passage through which refrigerant is supplied from the compressor to the first condenser. In the defrosting passage the refrigerant discharged from the evaporator is evaporated in the cold-storage device and then is supplied to the suction side of the compressor.
