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

2020 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon), 2020
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 ...
