空调水系统变流量节能控制分析
Energy saving analysis of variable water flow control in air conditioning water systems
摘要：
分析了变频调速水泵在三种控制（压差控制、温差控制、末端压差控制）方式下的运行过程、运行效果和节能效果，认为应综合考虑空调水系统的规模、负荷组成和分布、空调控制精度要求等因素选择最合适的控制方式。

Abstract：
Analyses the operating process, operating effect and energy saving effect of variable frequency pumps under three control methods, i.e. pressure difference control, temperature difference control and terminal pressure difference control. Suggests that the selection of control mode should be based on the scale of water system, the composing and distribution of load, the control precision demand of air conditioning system, etc.
Keywords:air conditioning water system, control, energy saving, variable water flow, variable frequency pump
