对变频离心式冷水机组全年节电的探讨

Discussion of reducing annual energy consumption of centrifugal chillers with variable speed drivers

介绍了变频离心式冷水机组节能的原理及适用条件。基于冷水机组的全年耗电量是冷水机组在不同运行时段内的机组能效、机组负荷与运行时间乘积之和,分析了1台变频离心式冷水机组在单台和多台机组中应用的节电效果。

Presents the principle and applicabilities of energy saving of centrifugal chillers with variable speed drivers. Analyses the annual energy saving of a centrifugal chiller with variable speed driver in the projects with one chiller or several chillers, according to their annual energy consumption that is sum of the product of the chiller efficiencies, loads and operation time in different operation periods.
