JAUE2022-072: Research on Home Decarbonized Heating Systems Using Solar and Biomass Heat

Abstract

In recent years, there has been an urgent need to promote CO2 reduction in households in order to achieve a decarbonized society.And we believe that we need to improve the heating system, which is a major source of CO2 emissions in the home.Therefore, we evaluated the heating and CO2 reduction effects of a decarbonized heating system using solar and wood biomass heat, both sustainable energy sources, in a household with the system installed, using measured data and simulations. The results of the measurement data confirmed that the subject dwelling units have a certain heating effect even when solar and biomass heat is used alone, and that this effect can be expected even under various outdoor air conditions. The simulation results confirmed that the use of a heating system combining solar and biomass heat could reduce the use of other heating equipment to about 70%. However, a total reduction of about 9% in CO2 emissions was confirmed when the electricity used by the pumps and fans of the subject heating system and the production of biomass fuel were taken into account
