The paper deals with the problem of using machine-free cooling in refrigerated trucks for intercity transportation in order to ensure environmental safety and to eliminate noise from a working refrigeration machine when unloading refrigerated products from refrigerated trucks to the distribution network. A machineless method for cooling the body of a refrigerator truck with cold accumulators without direct contact with a cooling medium due to the usage of frozen sealed containers is proposed. The accumulation of cold (AC) is carried out, as a rule, due to the heat of the phase transition at the melting point or crystallization of individual substances or there mixtures. The research of water-salt systems, which are widely used for temperature stabilization in refrigeration, for storage and transportation of medicines and food products, is presented. The results of the melting and freezing of three cold storage substances, which are H 2 O and water-salt solutions with NaCl concentrations of 8 and 13 % are presented. According to the results of studies, the usage of pressurized containers in refrigerated trucks with machine-free cooling is beneficial and opens up great opportunities for cooling the air in various destinations.
