The Applicability of Electric Heat Storage Technology in Clean Heating in Zhangjiakou Region

Zhangjiakou is one of the most important areas that have rich clean energy in China. The implementation of the clean heating system has a demonstration effect on the whole country. This paper firstly analyzes the important significance of the clean heating in our country at the present stage, and introduces the principle of electric heat storage technology; and then analyzes several schemes of clean heating renovation project with electric heat storage technology for a hospital in Zhangjiakou, and concludes that the solid electric heat storage scheme has good economic benefits. Finally, it is proposed to apply the implementation scheme of internet plus centralized and distributed clean heating of electric heat storage technology in Zhangjiakou, which can significantly improve the level of clean energy consumption and achieve greater social and economic benefits. The thinking of this paper is of great reference for implementation of practical projects.
