Clarification of Thermal Characteristics of the Solar Collector Integrated into Transparent Facade

The article focuses on current issues and the state of development of energy-efficient construction. The paper notes the need to implement alternative technological solutions in energy-efficient buildings. The need to improve the design of solar collectors integrated into transparent facades of buildings is analyzed. Also, the article proposes and studies an experimental design of a solar collector integrated into the transparent facade of the building. Data on the thermal characteristics of the proposed solar collector integrated into the transparent facade of the building are presented. The article analyzes the effect of simulated solar radiation on the process of heating the heat carrier in the mode of natural circulation in the solar heat supply system. The results obtained allow us to establish the thermal efficiency of the transparent facade integrated into the structure. It is established that the efficiency of the solar heating supply system in the mode of natural circulation of the heat carrier under the intensity 300 W/m² average 26%, and under the intensity 900 W/m^2–64%.
