Problems solved by technology
[0002] The variable temperature room has gradually become the standard configuration of refrigerators due to its versatility. However, because the variable temperature room can achieve large-span temperature changes, the evaporator is more prone to frost, which affects the cooling effect of the variable temperature room.
[0003] Most of the existing refrigerators use an additional electric heating device to defrost the variable temperature evaporator, but the effect of the above-mentioned defrosting method is not ideal, and the defrosting is uneven. In addition, the electric heating device will cause fire and other safety hazards. Additional energy consumption of the refrigerator

The invention provides a refrigerator and a refrigerating system thereof. The refrigerating system comprises a compressor, a primary condenser, a secondary condenser, a capillary tube, a freezing evaporator, a cold-storage evaporator, a variable-temperature evaporator and a switching unit; the switching unit is used for carrying out switching between a variable-temperature chamber defrosting modeand a normal refrigerating mode; the switching unit is provided with a first inlet, a second inlet, a first outlet, a second outlet and a third outlet; the first inlet is connected with an outlet of the compressor; the first outlet is connected with an inlet of the secondary condenser, wherein in the variable-temperature chamber defrosting mode, the first inlet is communicated with the first outlet; the second inlet is communicated with the second outlet; and further, the third outlet is closed. According to the refrigerating system of the refrigerator provided by the embodiment of the invention, after the secondary condenser is opened, the temperature of a refrigerant can be decreased while a variable-temperature chamber evaporator is defrosted; the refrigeration efficiency is improved; and the energy consumption is utilized adequately.
Description
technical field [0001] The invention relates to the technical field of refrigerator refrigeration, in particular to a refrigerator and its refrigeration system Background technique [0002] Due to its versatility, the variable temperature room has gradually become the standard configuration of refrigerators. However, because the variable temperature room can achieve large-span temperature changes, the evaporator is more prone to frost, which affects the cooling effect of the variable temperature room. [0003] Most of the existing refrigerators use an additional electric heating device to defrost the variable temperature evaporator, but the effect of the above-mentioned defrosting method is not ideal, and the defrosting is uneven. In addition, the electric heating device will cause fire and other safety hazards. Additional energy consumption of the refrigerator is increased. Contents of the invention [0004] The present invention aims to solve at least one of the above-m...
