摘　　要：以某小区热网为研究对象,建立了供热管网以及室内采暖系统的水力工况和热力工况的数学模型,分别对采暖系统在未进行初调节工况、仅改变供水温度工况及仅改变供水量工况进行了仿真计算,得出了房间的室温变化规律。通过对各房间室温变化规律的研究,确定建筑中的最不利立管及其最不利房间,为监测控制中温度传感器的优化配置提供了依据。Mathematical models of the hydraulic condition and thermal condition of heating system were established, taking a district heating system as an example .Simulation was carried out respectively on conditions of before the initial adjustment, simply changing the temperature or flow of water supply in the heating system. Therefore temperature variation of each room was obtained. By analyzing the rule of the temperature variation, we determined the most unfavorable tube and its most unfavorable room. It provides the basis for the optimized allocation of temperature sensor in monitoring and controlling system.

关 键 词：室内采暖系统 水力工况 热力工况 室温变化规律 最不利立管 最不利房间
