The refrigerator car is used as a van-type special cold chain transport car, can ensure the safe transport of perishable foods in a low-temperature environment, and is a key device for cold chain transport of roads. The traditional refrigerated vehicle is formed by additionally arranging a heat-insulating refrigerated carriage body and refrigerating equipment on a chassis special for a second-class truck, and can only meet the transportation requirement of low-temperature easy-to-store frozen products, but can not guarantee the durable fresh-keeping of some perishable foods (such as fruits and vegetables) in the long-distance transportation process, and the frozen transportation is carried out on the foods, so that the nutrition of the frozen foods can be gradually lost, more bacteria are generated, the frozen foods are gradually oxidized and deteriorated, the taste is poor, the acceptance of consumers on the frozen foods is low, merchants can only sell the frozen foods at a reduced price, and the economic benefit is lost. On the other hand, the traditional freezing or refrigerating mode is to make cold air by a refrigerating device to reduce the temperature of air, so as to realize low-temperature storage of food, but compared with the position far away from the air outlet, the air outlet of the cold air has obvious temperature difference, namely the problem of uneven distribution of the cold air in the space exists, and the fresh-keeping effect on partial food is difficult to control. In addition, in order to save the loss of energy in the long-term transportation process, when the internal temperature of the refrigeration compartment of refrigerator car reduces to the setting value, can close the refrigeration unit, when the temperature risees, open the refrigeration unit again, the electric quantity loss that frequent switch refrigeration unit caused is very big, also can reduce the life-span of equipment, and fresh-keeping time to food is very limited.

The technical scheme disclosed in the patent number CN214701411U is that a plurality of electric field emission plates are arranged on the wall of a refrigeration house to form an electric field, so that the fresh-keeping storage time of food is prolonged. However, according to the technical scheme, the plurality of electric field emission plates are arranged on the left side, the right side and the top of the refrigeration house, the generated electric field cannot realize the whole coverage and uniform coverage of the whole refrigeration house, and food materials with partial angles (such as positions close to a vehicle head and a parking space) cannot be acted by the electric field or the received electric field is weak.
