OPTIMIZATION OF PARAMETERS OF SOLAR COLLECTORS CONCENTRATORS FOR GREEN BUILDINGS

The use of solar collectors with solar concentrators in green buildings is an important step in the direction of creating energy-efficient and environmentally friendly buildings. These technologies make it possible to provide a sustainable source of energy, reduce emissions and save resources. Considering the positive aspects of using solar collectors, their implementation in construction can become an important step in the development of sustainable construction and environmental protection. The use of solar collectors with concentrators can significantly reduce the consumption of electricity and other energy sources, which is an important aspect for green buildings. These collectors are able to efficiently collect solar energy and concentrate it for further use in various heating, cooling and power generation systems. Increasing the energy efficiency of green buildings is possible due to the use of solar systems with optimal orientation parameters that use renewable, environmentally friendly solar energy for the energy supply of buildings. An analytical method has been developed to determine the optimal parameters - the angle of inclination of the solar collector reflector to obtain the maximum amount of converted solar energy, taking into account the number of glass layers, their transparency and absorption coefficient depending on the angle of incidence of reflected solar rays, shading by the collector frame, etc. Calculations were made and optimal angles of the reflector were determined for single-layer and double-layer glazing of the collector. The proposed method can be used in the design of green buildings that use solar energy for energy supply.
