With the development of China's economy, people's quality of life continues to improve, and the requirements for food quality and food safety are getting higher and higher, and reasonable storage of food is a basic requirement to ensure its quality. Cold storage technology is mainly used in cold storage board refrigerated trucks, thermal insulation materials, cold storage ice bags, and cold storage thermal insulation transport boxes in the low-temperature food distribution. Most perishable food must be stored in a low temperature environment, which promotes the development of the cold storage/low temperature storage industry. The application of cold storage technology to cold storage/low-temperature storage systems is the development trend of the cold chain logistics industry.
Wu Liyuan and others used water as the cold storage fluid and used an incubator to simulate a cold storage. They verified that the cold storage with cold storage board system within 8 hours of the peak electricity price has a temperature fluctuation of less than 0.6 ℃, and the maximum temperature difference at each point in the storage is 1.1 ℃, which can reach the cargo. Storage requirements and energy-saving effects, but it is prone to uneven temperature distribution. Liu M. et al. developed a refrigerated vehicle whose refrigeration unit is driven by electric power instead of an internal combustion engine. In this system, an insulating container with phase change material (PCTSU) is installed outside the refrigerated vehicle body, which is similar to the traditional refrigerated vehicle system. Compared with, it has the characteristics of low noise and low energy consumption.
Through numerical simulation and verification analysis, Copertaro B. et al. found that adding phase change material paraffin RT35HC to the enclosure structure of refrigerated trucks can reduce the peak daily heat load of refrigerated trucks by 20.01% to 20.87%; the peak heat load is delayed by 2 to 3 h, the daily energy consumption rate is reduced by 4.55% to 4.74%, which not only improves the cold storage performance of refrigerated trucks, but also reduces energy consumption. Jiang Yantao combined ice cold storage and wet cooling technology to design a set of dynamic ice slurry cold storage wet cold cold storage refrigeration system. Compared with ordinary cold storage, it has higher energy efficiency and less initial investment, and the temperature and humidity in the cold storage are constant, which is adaptable. Strong, energy-saving and environmentally friendly, good moisture retention, stable storage temperature and so on.
