Mathematical modeling appears to be a valuable tool for controlling the cooling and storage process of agricultural products. Therefore, mathematical modeling of the balance of heat and mass in refrigeration chambers is relevant. Mathematical modeling of the thermal regime of the thermal regime of a refrigeration chamber with a heat pump and determining temperature changes depending on time. Mathematical modeling is carried out based on the thermal balance of the refrigerating chamber by the method of conservation of mass and energy. It has been established that cooling and long-term storage of agricultural products in refrigeration chambers require a huge amount of electrical energy. At an outside air temperature of 30℃, it takes 30-40 minutes to cool products to the required temperature; for long-term storage, 5.5-6.0 kWh/day of electrical energy is consumed. A combined dryer-refrigerator with a heat pump for storing agricultural products is proposed and a mathematical model of the refrigeration chamber is given, which makes it possible to analyze the temperature regime in the refrigeration chamber.
