The main air supply channel 11 is used to transport the cold air generated by the evaporator 3 to the storage space;

The partition 4 is used to divide the storage space into a main refrigeration compartment 100 and at least one variable compartment 200 , and the partition 4 is also used to isolate the main air supply channel 11 from the variable compartment 200 Direct air supply.

Specifically, during the actual use of the refrigeration equipment in this embodiment, when the user needs to change the volume of refrigeration, the partition plate 4 can be installed in the storage space. On the one hand, the partition plate 4 divides the storage space into main refrigeration Compartment 100 and variable compartment 200, at the same time, partition plate 4 will also cut off the main air supply channel 11, so that the main air supply channel 11 cannot directly transport the cold air generated by the evaporator 3 to the variable compartment 200, for As far as the variable compartment 200 is concerned, if there is less demand for refrigeration space, the partition plate 4 can be adjusted to change the volumes of the main refrigeration compartment 100 and the variable compartment 200. The main refrigeration compartment 100 is still used for Normal refrigeration (refrigeration or freezing), while the variable compartment 200 can only be used as storage, for items whose storage temperature is normal temperature, it can be stored in the variable compartment 200, and due to the need for refrigeration capacity of the main refrigeration room The reduced volume of the chamber 100 greatly shortens the running time of the refrigeration equipment in this embodiment, and reduces the running power and energy consumption. At the same time, since the partition plate 4 uses a mechanical method to cut off the main air supply channel 11 instead of using the controllable damper for control and adjustment, the usage of the controllable damper can be greatly reduced, the manufacturing cost is reduced and the control process is simplified.

Further, along the air flow direction of the main air supply channel 11, the storage space is divided into a main refrigeration zone and a refrigeration variable zone, the main refrigeration zone is located in the space formed by the main refrigeration compartment 100, so The main air supply channel 11 is respectively provided with air outlets 111 in the main cooling zone and the cooling variable zone along the air flow direction, and the main air supply channel 11 is also provided with at least one The plate 4 is used to block the socket 112 of the main air supply channel 11, and the socket 112 is located in the cooling variable zone. Specifically, each air outlet 111 of the main air supply channel 11 is used to output cold air into the storage space, and when the partition board 4 is inserted into the corresponding socket 112, along the direction of air flow, it is located at the position where the partition board 4 is inserted.
