随着人们对供暖质量和要求的不断提高，利用先进的自动化技术、控制技术以及通讯技术，设计出高性能、高节能、适应供暖复杂环境的恒压补水系统已成为必然趋势。朔里矿业对原工人村区域供热补水系统进行了改造，实现变频恒压自动补水系统，其节能效果显著，稳定性大大提高。本文阐述了供暖热网补水系统改造的背景、工作原理、控制方案、变频恒压补水系统的运行性能，并进行了经济效益分析。%With the increasing demanding on the heating quality, using advanced automation technology, control technology and communication technology, constant pressure water supply system with high performance, high energy-saving and adapting to the complex heating environment was designed, and it become an inevitable trend. Heating water supply system of the former district of workers was transformed by Shuoli Mining, realized variable frequency and constant pressure automatic water supply system, and saved energy observably, stability was greatly improved. The modification background, work theories and control programs of water supply system in heating network, and the operational performance of variable frequency and constant pressure water supply system were advanced in this paper, and economic benefits were analyzed.
