Cold chain transportation refers to a transportation mode in which the transported goods always maintain a certain temperature in the whole transportation process. With the improvement of the living standard of people, the food safety awareness of consumers is continuously improved, and meanwhile, the rapid development of fresh electronic commerce drives the remodeling of domestic agricultural products, production places, processing places and consumer markets of cold chain foods, so that the Chinese cold chain transportation demand is rapidly increased under the promotion of a plurality of factors.

The transportation of the refrigerated carriage is one of the most important modes of cold chain transportation due to the advantages of large loading capacity, wide transportation coverage area, flexible operation and scheduling and the like. Among the refrigerated carriages, the mechanical refrigerated carriage realizes carriage refrigeration through a compression refrigerating unit, and is the refrigerated carriage with the most mature technology and the most wide application. In addition to mechanical refrigerated compartments, many other forms of compartment refrigeration technology are currently available, including electric field fresh food compartments.
