新型分户计量热水供暖系统阻力的测定方法

Hot-water Heating System of New Household Metering Friction Measurement

为解决供暖管材铺设错乱,系统难于管理等问题,辽宁省某公司开发了新型分户计量给水系统。本文通过水力学实验的方法对该系统进行阻力系数测定,得出该系统管件的阻力参数,采用回归方法得出管材在非设计工况下的阻力系数。结果表明:该种管材的阻力系数测量结果与实际符合的较好。

Disorganization of tube placing and difficult management of the system and so on, some companies in Liaoning developed a new kind of hot-water heating system of household metering. The paper provides measuring friction factors of this system by means of hydraulic experience, and obtains the parameter of the plumbing system in the off-design situation by regression method. The result shows that the measurement result of the parameter of the plumbing system is closest to the actual one.
