Research on Winter Heating Technology Pathways and Carbon Emissions in Urban Areas of Changchun
China has put forward the"3060"goal,that is,carbon dioxide emissions strive to peak before 2030,and strive to achieve carbon neutrality by 2060.As an integral part of the building,energy consumption and carbon e-missions of the building energy system are important areas of building energy conservation and emission reduc-tion.Low-carbon development of heating is one of the important means to achieve carbon peak and carbon neu-tralization,it is of great significance to realize low-carbon development of heating by replacing fossil fuels with clean energy.The current situation of winter heating in Changchun area is analyzed,including the development status of energy consumption in Changchun and the main heating technology paths in winter.To evaluate its car-bon emissions,it is necessary to first clarify the calculation method of carbon emissions from building energy sys-tems,and compare and analyze different clean heating technology paths through building simulation methods.The study shows that the highest carbon reduction in urban areas in Changchun is centralized biomass heating,fol-lowed by the technical path of coal-fired boiler heating,this result is mainly affected by the heating area.The re-sults of carbon reduction per unit area show that the most carbon reduction is the biomass boiler and heat pump heating technology path,and the unit carbon reduction of gas boiler and coal-fired boiler is less.In the compre-hensive evaluation,the best is the water source heat pump,however,the choice of heating technology path must be considered according to local conditions.
