摘要
变频调速恒压供水是供水领域新技术之一,具有高效、节能的特点,但它的前提是系统必须运行于高效率区内,否则就体现不出变频调速恒压供水的节能优势。本文对如何使变频调速泵及定速泵处于高效区工作进行了分析,提出了选用成套变频调速供水设备时,必须对其配套水泵结合系统设定的恒压值进行核算,以保证它的节能特点。
Variable frequency speed constant pressure governing water supply is a kind of new technology in water supply. It has the characteristics of high efficiency and energy saving. However the system must run in the zone of high efficiency, otherwise, it will not show the energy saving superiority. The paper analyzes the way variable frequency speed governing pump and constant speed pump work in the zone of high efficiency, the paper indicates that, when selecting a series of variable frequency speed governing water supply facilities, corresponding warer pump must be calculated considering the constant pressure value set to ensure the feature of energy saving.
