Method for determining the sizes of structural elements and semi-empirical formula of thermal characteristics of solar dryers

Abstract

By choosing the initial dimensions of flat solar collectors, and by measuring the temperature of the incoming and outgoing air from the collector, it is possible to determine the linear dimensions of the drying cabinet attached to the collector. It is also possible to establish the basic semi-empirical formulas for determining the thermal characteristics of solar dryers. This calculation method was applied to design and build a study of an indirect solar dryer with natural air convection for drying apricots.
