With the development of society and economy, people’s consumption and diet structure has been upgraded, and the demand for fresh products has grown rapidly. Especially since the outbreak of the epidemic, the demand for fresh food e-commerce and medical cold chain has continued to increase, and consumers’ food safety awareness has been continuously improved. Fresh products are driving the reshaping of domestic agricultural products, cold-chain food producing areas, processing areas and consumer markets, and cold-chain market demand is increasing rapidly.
Cold chain distribution is an important part of urban distribution. In recent years, the market scale of my country’s cold chain logistics industry has been expanding year by year. According to data, the scale has increased year by year from 180 billion yuan in 2015 to 469.8 billion yuan in 2020, and the development is very rapid. Therefore, the sales of refrigerated trucks have been continuously increasing. According to the data of the Cold Chain Committee of the China Federation of Things, the number of refrigerated trucks in my country will reach 275,000 in 2020, an increase of 28.1% from 214,700 in 2019.
As an important cold chain logistics transportation equipment, refrigerated trucks are closed vans used to maintain the temperature of frozen or fresh-keeping goods. Refrigerators are dedicated refrigerated transport vehicles equipped with refrigeration units with refrigeration units and polyurethane insulation compartments. Refrigerated trucks can be classified by manufacturer, chassis carrying capacity, compartment type, and cooling method. According to different refrigeration methods, refrigerated trucks can be divided into mechanical refrigerated cars, frozen plate refrigerated cars, liquid nitrogen refrigerated cars, dry ice refrigerated cars, and ice-cold refrigerated cars, among which mechanical refrigerated cars are the most common.
