摘　　要：对目前常用的热计量方法存在的问题进行分析,提出了一种基于集中供暖系统数学模型的分户热计量方法。以传热学和流体力学的相关理论为基础,建立了集中供暖系统的流量、压力和热损失数学模型,推导出了用户流量、供水端温度计算公式。该方法只需安装少量传感器就可实现分户热计量,降低了系统成本和维护费用,有利于热计量的推广使用。The problems of existing heat-meteri/lg mothods are analyzed. A household heat-metering method is proposed based on mathemati- cal model of the central heating system. Basing on the related theory of heat transfer and fluid mechanics, the mathematical modelof flow, pres- sure and heat loss of the central heating system are constructed, with the caculative formulas of flow rate and inlet temprature of heat consum- ers derived. Therefore the household heat-metering can be realized with only one fewer sensors. The expenses and maintenance costs of system is reduced, heloful for promoting the imolement of heat-metering.
