In the article, the authors proposed a combined device of a solar dryer-water heater with a heat accumulator (CDSDWHHA) for drying agricultural products using solar energy. As a research object - a connected device of a solar dryer-water heater with a heat accumulator, a drying drum installation, and an additional combined solar water-air heating collector for simultaneous heating of water and air was installed. Drying agricultural products is a technological process that requires a large consumption of thermal energy and fuel-energy resources. The results of the conducted analysis showed that electric heating devices are often used to operate such a system, which are always expensive and not economically acceptable. In this paper, in order to reduce the traditional energy consumption for drying agricultural products, a combined device of solar dryer-water heater with heat accumulator is proposed and experiments were conducted in the meteorological climate of Karshi city. As a result of experimental studies shows the heat load compensation and energy efficiency of the solar water-air heating collector drying device with a heat accumulator in the “water + air” heating mode. The installation efficiency was found to be in the range of 0.66 - 0.72.
