Classification of refrigerated containersRefrigerated containers can be simply defined as containers designed to transport frozen or low-temperature goods that require a certain temperature to be maintained. Refrigerated containers are used for long-distance transport of goods, not only in a very strong structure, but also able to withstand environmental changes. Refrigerated containers can be classified into four types according to the transport tonnage: micro, light, medium, and heavy. The temperature zone can also be divided. Temperature field distribution characteristics of refrigerated containersResearchers at home and abroad have done a lot of simulation and experimental researches on refrigerated containers, through the simulation of airflow [47,48,49] and the establishment of turbulence models and mathematical models, the theoretical model of refrigerated containers are getting better and better. At the same time, through the fan position, the shape of the air duct [52, 53], and the impact of the cargo position on the fresh-keeping capacity of the refrigerated container. Composition of road refrigerated truckThe refrigerated container has good heat insulation and shock resistance and can maintain a relatively stable low temperature. Refrigerated vehicles are specialized vehicles that transport perishable goods. The main areas of use include cold drinks, eggs, and fisheries, as well as industrial, mining, military, and medical sectors. Road refrigerated transport has become the main body of Chinese refrigerated transport market due to its developed road network which is convenient and flexibl. Temperature field distribution characteristics of refrigerated trucksThe arrangement of the cold storage plates to check whether or not the cold storage plates have an effect on the temperature field distribution in the refrigerated vehicle is important. Xie et al. conducted a simulation study on the temperature field of the no-load refrigerated compartment under three different cold plate layouts (cold plate overhead, cold plate side, and cold plate part overhead part side). When the cold plate is placed sideways, the temperature in the car is low and th. Temperature field distribution characteristics of insulation boxThe insulation box of cold storage is made of a material with low heat insulation or low thermal conductivity, and a cold accumulator is placed inside to keep the temperature inside the box so that the cold chain transportation of the food is conveniently completed. The packaging device combining the insulation box of cold storage and the cold storage agent is different from the active refrigeration device such as the refrigerating truck and belongs to a passive cold chain packaging method. I. Advantages and disadvantages of insulation boxAt present, there are many types of cold storage tanks on the market, and there are many advantages in the use of refrigerated transport, but there are also some shortcomings in practical use. (a) Cool storage equipment is required. Pre-cooling of the cold storage plate is required when using the cold storage tank, which requires professional cold storage equipment. Especially for enterprises with cold chain logistics, due to the large number of cold storage tanks used, special cold storage s.
