Kozak K. Providing the thermal state in the rooms by solar air heating systems

The dissertation is devoted to solving the relevant issue of increasing the efficiency of heating systems based on solar air collectors. Based on physical and computer modeling, the feasibility of using flow turbulators in the design of an air solar collector has been substantiated. Complex of theoretical and experimental researches on determination of regularities of formation of the thermal state in the premises by the system of solar air heating is fulfilled. The influence of turbulators of air flow, structural parameters of the solar collector on its thermal and aerodynamic characteristics at the variable intensity of solar radiation is determined. Based on theoretical and experimental researches carried out the energy-saving design of the SAC with flow turbulators has been developed. Technical solutions for enhancement of heat engineering characteristics of the solar air collector have been suggested. In particular, in the air channel along the heat carrier movement, flow turbulators made of sheet steel as a circular twisted conoid with a selective coating have been installed. Flow turbulators provide additional heating area and heat exchange processes intensification in the SAC air channel.
