简要介绍了供暖系统定压补水的必要性和系统的基本工艺原理,结合实际应用,分析了系统定压补水的多种自动控制方案及应用,其中重点介绍了系统压力测点的选取及变频调速技术在定压补水控制中的应用。该控制方案也适用于中央空调冷冻水系统定压补水自动控制。
The necessity of constant pressure replenishment for heating system and the basic process principle of the system are briefly introduced. Based on the practical application, a variety of automatic control schemes and applications of constant pressure replenishment are analyzed. The selection of pressure measuring points and frequency conversion Application of Speed Technology in Constant Pressure Water Supplying Control. The control scheme is also suitable for central air conditioning chilled water system constant pressure water automatic control.
