Title:
DEFROSTING SYSTEM AND REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2020/143777
Kind Code:
A1
Abstract:
A defrosting system, applied in a refrigerator, and comprising a compressor (10), a condenser (20), and an evaporator (30). A fan (33) is provided on the evaporator (30). The defrosting system further comprises a communication-switching device (90) and a regenerator (50). A first port of the communication-switching device (90) is connected to a gas outlet of the compressor (10), a second port is connected to an inlet of the condenser (20), and a third port is connected to a defrostation water tray and defrosting pipe (34) thereof. A sub-cooling coil (51) and a cold-accumulator coil (52) are provided in the regenerator (50). One end of the sub-cooling coil (51) is connected to an outlet of the condenser (20), and the other end is connected to a gas inlet of the evaporator (30) by means of a first filter drier (61) and a first throttling device (41). One end of the cold-accumulator coil (52) is connected to a gas outlet of the evaporator (30) by means of a second throttling device (42) and a second filter drier (62), and the other end is connected to a gas suction inlet of the compressor (10) by means of a liquid storage container (70). The gas outlet of the evaporator (30) is further connected to a solenoid valve (80) and the liquid storage container (70). The defrosting system of the technical solution employs the principle of heat of condensation to achieve rapid defrosting, resulting in minimal compartment temperature rise, and highly efficient defrosting.
