Application and research progress of cold storage technology in cold chain transportation and distribution

This paper reviews the application and research of cold storage technology in cold chain transportation and distribution and points out the research prospects of transportation equipment and the problems that need to be solved. The advantages and disadvantages of refrigerated containers, refrigerated trucks and insulation box of cold storage were compared and analyzed. Three types of cold storage devices are applied to the cold chain logistics to achieve efficient and economical cold chain distribution systems. Because of its high energy storage density, phase change materials have become a research hot spot in the field of energy storage. Therefore, phase change cold storage materials have great potential applications in cold chain transportation and distribution. The performance improvement of cold storage materials, rational design of storage tanks, and simulation of temperature field under the influence of different factors in cold storage equipment should be the focus of future research on cold storage transportation and distribution.
