Cold sources for cooling refrigerated vans are divided into temporary ones, ensuring the maintenance of the required temperature in the body without recharging the batteries for cold cooling for a limited period, and constant, ensuring the maintenance of the set temperature without periodically renewing the supply of cold. Temporary sources of cold include ice-salt mixture, dry ice, frozen eutectic solutions, installations with liquid nitrogen. A constant source of cold is engine cooling. Dry ice cooling is devoid of the main disadvantages of other methods. It has a relatively high refrigerating effect with a relatively small volume occupied by dry ice. Dry ice cooling can be carried out by contact and non-contact methods. In the contact method, the blocks of dry ice are not separated from the product, due to which carbon dioxide pairs wash the products. With the non-contact method, dry ice is loaded into hermetically sealed containers. The authors have proposed an environmentally friendly, reliable scheme of the process of cooling the body of a refrigerator with carbon dioxide using electrophysical methods. EGD devices with moving and stationary electrodes developed by the authors were used as pathogens for the circulation of the gas mixture in an isothermal body, which allowed to reduce the consumption of solid carbon dioxide.
