In the scientific laboratory of Bukhara State University, experiments were carried out on air-solar technology for drying apricots on solar installations. In the proposed solar system, the phenomenon of natural convection is created by additional shutters. Concepts were selected, on the basis of which a computational and computational method was developed and the geometric dimensions of the elements of a direct-type dryer were determined. The formula for the ratio of the dimensions of the height to the length and, accordingly, to the width of the dryer has been established, and a method for determining the dimensions of the dampers has been developed, designed for the flow of air from the environment into the chamber and for the exit of the vapor-air mixture from the inside of the chamber of the dryer into the environment. Such methods of choosing the sizes of the elements of the dryer create an optimal mode of their operation, and also create a natural convection circulation of air inside its chamber. The results of experiments carried out on the manufactured solar device are analyzed graphically.
