Design and research of electric heating as the core of energy system renovation of existing buildings

Abstract

With the implementation of China’s two-carbon strategy, how to achieve clean heating, especially the construction of a heating system with electricity as the core, has become a research hotpot in the industry. Among them, air source heat pumps, ground source heat pumps and energy storage have become important technical measures. In view of the capacity increase of urban heat exchange stations, combined with regenerative electric boilers and electricity price reform, this paper uses valley electricity for heat storage, and based on economic analysis, the municipal heat network is increased in flexibility and cleanliness, air energy, coupled energy storage clean and low-carbon heating transformation strategy.
