热水锅炉供暖系统PID变频定压技术研究

The PID frequency-changing and voltage-stabilizing technology in a hot water heating system

热水锅炉供暖系统PID变频定压技术在小型供暖系统中应用良好,但这种一般的PID变频定压系统在大型供暖系统的安装调试过程中发现常出现循环不畅等问题,存在暴管、暴暖气片等很大的危险隐患,现将出现问题的原因做一分析并对解决问题的方法加以论述。

The PID frequency-changing and voltage-stabilizing technology is used well in small hot water heating systems, but some problems of bad circulation exist in large ones with potential dangers such as pipe and radiator explosion. The reasons and solutions for above problems are discussed in this paper.
