Benefit Analysis and Comparison of Electric Heating System for Municipal Central Heating

Abstract

Electric heating can not only relieve the pressure of municipal central heating but also help to solve the problem of wind and light abandonment, which is an important direction for the future development of central heating. To maximize the comprehensive benefits, this paper constructs three kinds of electric heating systems. According to the comprehensive benefit evaluation of technical, economic, and environmental aspects, the comprehensive optimal scheme is selected. An office area in Beijing is taken as an example to determine the optimal scheme of electric heating and heating supplement. The results show that the comprehensive benefit of the heat pump + phase change accumulator system is the best, but the environmental benefit needs to be further improved. To promote the pace of electric heating and heating supplement, the government should increase the subsidies for electric boiler technology. At the same time, clean energy power supply enterprises should improve the trading mechanism of the electric heating market and reduce the price of clean energy heating.
