摘　　要：随着人民对美好生活的向往,城市社区各类建筑的冷热需求逐步上升,空调能耗在全国总能耗的占比不断上升,成为能源消费新的增长点。特别是未采用集中供暖的夏热冬冷地区,多采用分散式冷暖空调方式,存在着能源利用效率低、舒适性差和安全隐患等问题。结合国内外的相关研究,从能源供应方式的角度对城市社区综合能源服务进行了探索研究,通过建设集中供能站及配套管网,为社区内商业建筑、住宅、公建、酒店等建筑物供应冷暖,利用建筑群的集约效益实现可再生能源的规模化利用和多种能源的互补利用,通过统一建设、运行和管理,节约社会资源,提高能源利用效率,保护生态环境,促进城市低碳高质量发展。以某夏热冬冷地区的未来社区为例,总供能建筑面积为14.57万m^(2),介绍了“地源热泵+热源塔+水蓄冷”多元协同的集中供能技术的技术方案和工程实践经验,并进行了经济性分析和社会效益定量评估。结果显示,相比传统的“冷水机组+燃气锅炉”系统,该技术每年可节约标准煤613.04吨,减少二氧化碳排放1495.2吨。With the people's aspirations for a better life gradually rising,the cooling and heating needs of various types of buildings in urban communities are gradually rising,and the share of air-conditioning energy consumption in the total national energy consumption is increasing,becoming a new growth point in energy consumption and receiving attention from all sides.Especially in the hot summer and cold winter areas where centralised heating is not used,decentralised cooling and heating air-conditioning methods are mostly used,which have problems such as low energy use efficiency,poor comfort and safety hazards.Combined with relevant research at home and abroad,an exploratory study of integrated energy services for urban communities has been carried out from the perspective of energy supply methods.Through the construction of centralised energy supply stations and supporting pipeline networks,it supplies cooling and heating air-conditioning for commercial buildings,residential buildings,public buildings,hotels and other buildings in the community,utilising the intensive benefits of building clusters to realise the large-scale utilisation of renewable energy sources and the complementary utilisation of a variety of energy sources,and,through the unification of construction,operation and management,to Through unified construction,operation and management,it saves social resource input,improves energy use efficiency,protects the ecological environment,and promotes low-carbon and high-quality development of the city.Taking a future community located in an area with hot summer and cold winter as an example,with a total energy-supply building area of 145,700 m^(2),the technical scheme and engineering experience of the centralised energy supply technology with multiple synergies of‘ground source heat pump,heat source tower and water storage and cooling’are elaborated in detail.Economic analysis and quantitative evaluation of social benefits were also carried out,and the results showed that compared with the traditional�
