电化学储能电站余热用于建筑供暖的节能性分析
Energy-saving analysis of heat utilization for buildings using residual heat from electrochemical energy storage station
摘要
Abstract
During the charging and discharging processes of electrochemical energy storage stations,substantial amounts of waste heat are generated and dissipated to the environment via the cooling medium.Recovering and utilizing this thermal energy is essential for enhancing utilization energy efficiency.Based on an analysis of the waste heat characteristics during the charging and discharging processes,this study develops a heat-pump heating system integrated with waste heat recovery.This study compares the electricity consumption,carbon dioxide emissions,and related performance indicators of this system with those of coal-fired boilers and heat-pump heating systems without waste heat recovery.The results show that the average supply water temperature of the electrochemical energy storage station waste heat heating system is 47.31℃,with an electricity consumption of 818.65 MWh,which is 95.86 MWh lower than that of the heat-pump heating system without waste heat sources.The coefficient of performance(COP)of the waste heat heating system is 4.255,which is 0.405 higher than that of the heat-pump heating system without waste heat sources,representing an increase of approximately 10.52%.The carbon dioxide emissions of the waste-heat system are 792.45 t CO2/a,representing reduction of 859.16 t CO2/a(10.48%)and 92.8 t CO2/a(52.01%)compared with the coal-fired boiler and the heat-pump heating system without waste heat recovery,respectively.关键词
