Rural house heat supply system based on solar energy
Abstract
The article examines the solar energy-based heat supply system of individual rural houses as the object of research. Currently, the volume of construction of standard houses in rural areas of the Republic of Uzbekistan is growing, which in turn leads to the problem of saving traditional energy resources and uninterrupted heat supply in their heating system. The authors proposed a scheme of a combined heat supply system with a flat solar collector and a water heating boiler in order to save fuel energy resources in the heating system of rural houses. In the article, experiments and measurements were carried out on the basis of experimental calculation methods in a solar heating system installed in an experimental solar house. Based on the conducted experiments, the thermal-technical characteristics of the proposed system, the thermal efficiency of the collector and the temperature regime were analyzed. The results of the study show that the maximum heat output of the flat solar collector was 8.7 kW, and the temperature of the hot water at the entrance to the heating system was 45-50 0C. As a result of the application of the proposed combined heat supply system, 50% of the heat load in the daytime mode on sunny days was covered by solar energy.
