热水供热系统变频循环水泵节能分析

Energy saving analysis of the variable frequency circulating water pump in a hot water heating system

针对目前供暖系统采用质调节和分阶段改变流量质调节的现状,提出在供热系统供回水恒温差工况下,使用变频循环水泵改变流量调节的方法,从理论上分析了该方法在节能方面的优势。

In view of the status of the current heating systems adopting qualitative operation and staged variable flow qualitative operation, puts forward the adjustment method of adopting variable frequency circulating pump to regulate the flow rate under the condition of constant temperature difference between supply water and return water, and theoretically analyses the energy saving advantages of the method.
