At this time, the refrigerant enters the condenser 2 from the outlet of the compressor 1, and after being fully condensed and radiated in the condenser 2, the refrigerant is throttled and depressurized by the capillary tube 4 and enters the evaporator 5. The refrigerant is evaporated in the evaporator 5 to be converted into low-temperature low-pressure gas, and then sucked into the compressor 1, and the next cycle is performed.
When the refrigerator detects that the refrigerator is in embedded installation at the moment, and the heat dissipation condition of the press bin is bad, the inlet 601 is communicated with the first outlet 602. At this time, the refrigerant enters the condenser 2 from the outlet of the compressor 1, and the refrigerant is partially condensed and radiated in the condenser 2 and then enters the auxiliary condenser 3. The refrigerant is throttled and depressurized by a capillary tube 4 to enter an evaporator 5 after fully exchanging heat with the phase change material in an auxiliary condenser 3. The refrigerant is evaporated in the evaporator 5 to be converted into low-temperature low-pressure gas, and then sucked into the compressor 1, and the next cycle is performed.
