摘　　要：以山西省太原市某住宅小区供暖系统为研究对象,对场区周边再生水水温、水量、水质及燃气、电力、热网等资源条件进行评估,综合建筑供暖季逐时负荷,提出了分区域的单独再生水源热泵系统+单独燃气锅炉系统分别满足部分住宅区全部建筑供暖需求及全集中式的再生水源热泵+燃气锅炉复合式系统满足全部建筑供暖需求两种热源方案,分析了两种方案能源系统供能占比、运行原理及设备配置情况,对比了两种方案与城市热网供暖方案的初投资、运行费用及投资回收期等经济性指标以及节煤、节电、减碳、减排等环保性指标。结果表明,复合式再生水源热泵系统节费率55.4%,节能率53.5%,减排CO_(2)量3898.35 t,具有较好的节能、环保及经济效益。A residential heating system in Taiyuan is researched, evaluating its reclaimed water temperature, water quantity, water quality, gas, electricity, heat and other resource conditions around the site. Combined with the hourly load of building heating season, two heat source schemes are proposed,namely, the separate regenerated water source heat pump system + separate gas boiler system in different areas to meet the heating needs of all buildings in some residential areas, and the fully centralized regenerated water source heat pump + gas boiler composite system to meet the heating needs of all buildings. The energy supply ratio is analyzed, as well as the operation principle and equipment configuration of the two energy schemes, compared the economic indicators and environmental indicators such as initial investment, operating costs, investment payback period, power saving, carbon reduction, and emission reduction between the two schemes and the urban heating network heating scheme. The results show that the composite reclaimed water source heat pump system has good energy saving, environmental protection and economic benefits.
