Thermal calculation of solar heat supply of a building
Problem statement. The thermal design were carried out based on the analysis of available solar energy and climatic data of the Republic of Tatarstan. Evaluation of the possibility of using heliothermal heat supply in climatic condition of the district were conducted. Results. Traditional heating and hot water supply system were designed for a particular building. The thermal design of solar thermal heating systems, solar thermal hot water supply and combined system (traditional heating and solar thermal hot water supply) were performed according to the estimation of the available amount of solar energy and climatic data of the Republic of Tatarstan. Conclusion. Comparison of thermal characteristics of constructive elements showed that the combined heat supply system of this building during 26 weeks fully meets heat supply requirements. The solar energy of given climatic region in winter cannot provide the necessary amount of heat power, and as a result cannot create a comfortable indoor climate in the building.
