The refrigeration system may include components such as a compressor 10, an evaporator 2, a condenser, and a capillary tube, which are interconnected by piping. Refrigerant may be circulated between different components of a refrigeration system through piping. Wherein the refrigerant is liquefied in the condenser and releases heat to the outside, and the refrigerant is vaporized in the evaporator 2 and absorbs heat from the outside.
The refrigerator 100 may include a cabinet 11, and a storage compartment 12, a cabin 13, and an evaporator 1 may be formed in the cabinet 11. A supply air duct 14 and a return air duct 15 can be communicated between the evaporator chamber 1 and the storage compartment 12.

In the present embodiment, the air return opening 4 is disposed toward the evaporator 2 so as to ensure that the evaporator 2 can rapidly and sufficiently cool the air flowing into the evaporator chamber 1 through the air return opening 4.
In this embodiment, the arrangement of the defrosting heating element 5 and the air return opening 4 may be: at least one side surface of the defrosting heating member 5 is arranged towards the air return opening 4, and the projection of the defrosting heating member 5 towards the front surface of the air return opening 4 can cover the air return opening 4. By the arrangement, the defrosting heating element and the air return opening can be in spatial correspondence with each other in the facing area.
Due to the low surface temperature of the evaporator 2, water molecules in the gas partially condense into frost and adhere to the evaporator 2 during the process of flowing through the evaporator 2.
In order to ensure the heat exchange efficiency between the evaporator 2 and the gas, the evaporator 2 may be defrosted with the defrosting heating member 5. The defrosting heating member 5 may be provided around the evaporator 2 to melt the frost layer on the evaporator 2 by generating heat.
In this embodiment, the heat distribution may refer to how much heat can be generated in different areas of the defrosting heating member 5 per unit time. For example, the defrosting heating member 5 may be configured such that the amount of heat generated per unit time is large in the central region and small in the peripheral region.
The amount of heat that can be generated per unit time affects the defrosting effect and the time required for defrosting. The more heat can be generated in unit time, the less defrosting time is needed, the higher defrosting efficiency is, and the better defrosting effect is.
When the frosting volume of the different regions of evaporimeter 2 with change the heat of white heating member 5 corresponding position department in direct proportion, it is also that the place that evaporimeter 2 frosted much corresponds with the place that changes white heating member 5 and produce heat much, evaporimeter 2 frosted less place and change white heating member 5 and produce the place that heat is few and correspond when, 2 holistic frosting efficiencies of evaporimeter are higher, can effectively shorten the defrosting required time, can reduce the energy waste simultaneously, reduce energy consumption, and it is better to change the frost effect, still remain the phenomenon that has the surplus frost on the evaporimeter 2 after can avoiding appearing changing the frost.

Therefore, when the frosting distribution of the evaporator 2 corresponds to the heat distribution of the defrosting heating part 5, the temperature fluctuation of the storage chamber 12 can be reduced, and the freezing and fresh-keeping effect of the storage chamber 12 is improved.
In the present embodiment, the air volume distribution may refer to a distribution of the amount of the gas flowing through the same cross section in a unit time in different regions. The cross section may refer to a plane perpendicular to the gas flow direction.
The more gas flows through the evaporator 2 per unit time, the more water molecules are carried, and accordingly, the more frost condenses on the evaporator 2. Thus, the frost distribution on the evaporator 2 can be adjusted by adjusting the air volume distribution flowing through the evaporator 2. When the air volume distribution flowing through the evaporator 2 is consistent with the heat distribution at the corresponding position of the defrosting heating member 5, correspondingly, the frosting distribution of the evaporator 2 is consistent with the heat distribution at the corresponding position of the defrosting heating member 5.
In addition, since the gas flows from the return air opening 4 to the evaporator 2, the air volume adjusting module 7 and the air volume adjusting module 7 are provided at the return air opening 4 to enable air volume adjustment.
