Description

technical field [0001] The invention relates to the technical field of heating, ventilation and energy saving, in particular to an interseasonal phase change energy storage system. Background technique [0002] Since 2020, my country has successively clarified the dual carbon goals of "strive to reach the peak of carbon dioxide emissions by 2030 and strive to achieve carbon neutrality by 2060". [0003] According to the distribution of global greenhouse gases by industry jointly released by the World Resources Institute and Climate Watch, the total global greenhouse gas emissions in 2016 reached 49.4 billion tons, of which 73.2% of greenhouse gas emissions came from energy consumption. According to the data analysis and summary of the China Carbon Accounting Database (CEADs), the electricity and heat production industry is the most important source of carbon dioxide emissions in China. [0004] The basic situation of heating in my country: increasing demand, insufficient su...
