USING PARABOLOID SOLAR CONCENTRATORS TO IMPROVE THE THERMAL EFFICIENCY OF BUILDINGS

Abstract

In this study, the potential for reducing the specific heat consumption of residential buildings in the Tashkent climate was examined by utilizing a solar parabolic concentrator in combination with a heated floor system. The developed mathematical model incorporated both the solar concentrator and the heated floor system, and the calculations were carried out using the Mathcad and Python programming environments. The findings indicate that the annual specific heat consumption can be decreased by up to 71% with the implementation of these systems. The payback period for the investment, depending on the level of thermal insulation, ranges from 3 to 7 years, while the reduction in greenhouse gas emissions is estimated to be between 3 and 22 kg/m².
