摘要
“双碳”目标下,通过可再生能源和综合能源系统实现清洁供暖(冷)是拓展现有供热能力、解决供暖(冷)民生需求、实现建筑节能减排的重要途径。以我国北方某商住园区综合能源供暖(冷)项目为研究对象,依次开展项目负荷分析、区域资源分析和冷热源优化分析,提出2种“集中热网+可再生能源”综合能源供暖(冷)方案。通过装机方案和运行经济性对比分析,结果表明:相比于方案2,方案1减少了空气源热泵,增加了蓄能系统并以电锅炉作为极寒期的调峰热源,供暖季运行电费和购热费合计减少18.6%,制冷机组装机减少30.8%,供冷季运行电费减少35.4%,年运行成本降低20.8%。研究成果将为同类型综合能源项目的方案设计和运行策略优化提供借鉴。
In the context of dual carbon,combining renewable energy with integrated energy systems is an important way to expand the current heating capacity and provide clean heating(cooling),so as to meet people′s livelihood needs,and achieve building energy conservation and emission reduction simultaneously.Taking the comprehensive energy heating(cooling)project of a commercial and residential park in north China as the research object,this paper carries out project load analysis,regional resource analysis,and cold and heat source optimization analysis,and puts forward two comprehensive energy heating(cooling)schemes with"central heat network+renewable energy"concept.Scheme 1 removes air source heat pumps,adds an energy storage system and uses an electric boiler as heat source in extremely cold periods.The results of the comparative analysis on two installation schemes and operational economy show that the total expense including electricity bill and heat purchase cost in heating season of scheme 1 is 18.6%lower than that of scheme 2.And the installation capacity of refrigeration unit,electricity bill for cooling,and annually operational cost of scheme 1 are 30.8%,35.4%and 20.8%lower than that of scheme 2,respectively.This analysis provides reference for the design and operation strategy optimization of integrated energy projects of the same type.
