浅谈采暖空调系统恒压点的定压

On constant pressure for constant pressure point in heating air-conditioner system

探讨了采暖空调系统恒压点的作用及数值,分别论述了膨胀水箱、气压罐和变频补水泵三种定压方式的工作原理、设计选型及特点,为采暖空调系统的正常运行提供了保障。

The paper explores the role of constant pressure point of the heating air-conditioner system and its value,and indicates the working principles,the design styles and the features for the three constant pressure ways,that is,expansion water tank,pressure tank,and variable frequency pumping,and provides the guarantee for the common operation for the heating air-conditioner system.
