[0002] Cold chain logistics is the key circulation route for food from its place of origin to the user. Through refrigeration or freezing, it can ensure that the quality of food will not be damaged too much during transportation. During the cold chain logistics transportation process, the interior of the transport compartment needs to be cooled by a refrigeration air system to prevent logistics food from deteriorating due to high temperatures.

[0003] For example, the utility model: "A refrigeration air system for cold chain logistics vehicles", with the announcement number: "CN209079597U", sets up a heat dissipation air system, so that the heat generated by the refrigerator during operation can be quickly dissipated into the outside air, and the cold can be evenly transferred to the food in the car. The cold chain logistics vehicle can reduce energy consumption while ensuring the freezing effect. However, during the implementation of this patent, the cold air temperature cannot be automatically adjusted, and it is not easy to keep the temperature inside the car within a stable range. In addition, during the refrigeration process, it is not easy to blow the cold air evenly to different positions inside the car, and it is not easy to keep the temperature uniform at different positions inside the car. Therefore, the research and development of new refrigeration air systems for cold chain logistics vehicles has received more and more attention from researchers. Utility Model Content
