摘　　要：针对某既有建筑群集中供热热源改造问题,从当地电力政策实际状况和系统经济运行的角度出发,提出电锅炉水蓄热首站供暖、固体蓄热电锅炉首站供暖和分布式固体蓄热电锅炉供暖3种热源改造方案。建立系统数学模型对三种热源改造方案进行比较选择。结果表明,分布式固体蓄热电锅炉供暖系统切合实际状况且性价比最高,较前两种方案每年分别节约成本4.52%、10.33%,可作为热源改造方案。此设计思路可为北方地区既有建筑热源改造的设计提供一定的参考。Aiming at the problem of heat source transformation in an existing building cluster,from the perspective of local actual situation and system economic operation,three heat source transformation schemes are proposed:first station heating of electric boiler water heat storage,first station heating of solid heat storage electric boiler and heating of distributed solid heat storage electric boiler.A systematic mathematical model was established to compare and select three heat source transformation schemes.The results show that the distributed solid thermal storage electric boiler heating system is realistic and cost-effective,and the annual profit is 14.69 million yuan and 8.12 million yuan more than the previous two schemes,which can be used as a heat source transformation scheme.This design idea can provide a certain reference for the design of existing building heat source renovation schemes in northern China.
