Possibilities of Using a Low-Potential Heat Source for Heating Buildings in Regions with a Cold Climate

Abstract

Due to the high demand for heating in Yakutia, high greenhouse gas emissions per capita. The use of renewable energy in heating can reduce greenhouse gas emissions. A review of works in Russia on the use of solar energy in hot water supply and heating shows a constant trend towards an increase in the area of used solar collectors and the volume of the storage tank. This work looks for the maximum possible parameters for using solar energy in heating. The formula for calculating the temperature of a heat accumulator of the simplest spherical shape is given. A method is proposed for calculating the temperature of the heating agent in the system solar collector - water heat accumulator - an ordinary village house. The estimation of the calculation accuracy was made. As a first approximation, the total aperture area of solar collectors, the dimensions and mass of a water heat accumulator, which allow in regions with cold climates to completely replace the traditional fuel for heating a standard village house with solar energy, are determined. The overall efficiency of use of the annual energy of solar radiation has been obtained, and ways to further improve the efficiency of the solar heating system are shown.
