摘　　要：从就近利用小区污水冷热能的角度出发,对重庆市主城区某居住小区生活污水的温度和流量进行了测试分析,提出了小区污水热泵系统应用于建筑空调、供暖和卫生热水供应的综合节能系统模式;调研了小区生化池内污水温度分布,分析了小区污水逐时流量及逐月流量的变化,讨论了小区污水所能提供的冷量与建筑实际需要冷负荷的匹配关系,提出了生活小区污水热泵系统与常规冷热供应系统的复合式冷热供应方案。The temperature and flow of domestic sewage from a residential area in Chongqing City were tested and analyzed for the nearest utilization of cold and hot energies from the sewage. An energy saving mode of sewage-source heat pump system applied for building air-conditioning, heating and sanitary hot-water supply was put forward. The sewage temperature distribution in the biochemical tank in the residential area was investigated. The variation of hourly and monthly flow rates of the sewage was ana- lyzed. The matching relationship between cold energy provided by the sewage and the cooling load needed for the buildings in the residential area were discussed. A combined cooling and heat supply scheme by using sewage-source heat pump and traditional cooling and heat supply system to farthest utilizing the sewage energy was proposed.
