Research progress on refrigeration technologies of car refrigerator.

With the improvement of the national economic level and the diversity of medical equipment needs, the car refrigerator as an important carrier in the cold chain logistics link is rapidly developed. According to the different applications, there are differences in the refrigeration technologies and cooling capacity of car refrigerators. Around car refrigerators, the development status of car refrigerator refrigeration technologies is reviewed, the characteristics and functions of car refrigerators are introduced, the mechanism and characteristics of several refrigeration technologies under different scenarios are studied, and the potential development and application directions of car refrigerators with different refrigeration technologies are summarized. The research results are of certain practical significance to the improvement of the last-mile of cold chain logistics. [ABSTRACT FROM AUTHOR]
