变频供水技术在集中热水供水系统中的应用

Frequency conversion technology in the application of hot water supply system

从变频供水的两种方式:变频恒压与变频变压(变流量)供水,变频器的控制模式,以及辅助泵和小气压水罐的选用等方面讨论了变频供水技术在集中热水供水系统中的应用,得出结论:应选择特性曲线较陡的水泵,优先选用变频变压(变流量)供水方式,采用双变频器控制模式,并经计算后选用合适的辅助泵和小气压水罐,以保持管网压力稳定。

Frequency conversion technology in the application of hot water supply system are discussed from two ways of Frequen- cy conversion water supply： frequency conversion constant pressure and Variable Voltage variable frequency（waterl, inverter control mode, and the auxiliary pump pressure tank and then draws a conclusion that the application should choose characteristic curve steep pumps, plus choose variable frequency variable pressure （flow） of water supply, using double inverter control mode, and the calculation of the auxiliary pump and appropriate pressure tank, small pipe pressure to keep stable.
