摘要
对重庆某三级污水管网的流量动态特性、温度动态特性进行了分析，对某商场建筑的全年负荷进行了模拟。在此基础上，比较了商场建筑日峰值排热量与污水平均载热量的相对大小，找出最不利流量及其与建筑需求侧的差额。为了充分、合理的利用城市污水冷热资源，探索在污水流量不利工况下城市污水与城市建筑负荷之间的供需匹配方法，采用复合式系统弥补全年污水最不利流量时段污水平均载热量与建筑负荷的差值，并针对复合式系统提出了负荷分担原则及控制策略。
Abstract
Flowing dynamic characteristics and its temperature dynamic characteristics of a three‐level sewage pipe network in Chongqing were analyzed .A mall's building whole year load was simulated .In the adverse condition of wastewater flow ,the market construction peak discharge heat was compared with the sewage heat load ,the balance between the most adverse flow and the building demand was found .Explored supply and demand matching method between urban sewage and city building load in flow adverse condition to take full advantage of the urban sewage cold and hot resources .the composite system was adeptcd to make up the most unfavorable flow time of sewage average heat load and the construction load difference ;it also puts forward principle of load sharing and control strategy aimed at compound system .
