变风量空调系统的优化控制
Optimized control of VAV air conditioning system
摘要：
从变风量末端装置控制、空调机组送风温度控制、空调机组风机转速控制、空调系统新风量控制4个方面介绍了变风量空调系统的优化控制原理。每个方面都从控制目标、控制对象、控制逻辑明确了各控制环节要做什么、如何做好的关键环节。

Abstract：
This paper presents the optimized control principle of the variable air volume (VAV) air conditioning system from four aspects, including the VAV terminal unit control, the supply air temperature control of the air handling unit (AHU), the fan speed control of the AHU, and the outdoor air volume control of the air conditioning system. Each aspect is clarified in terms of what each control action should do and how to do it well in terms of control targets, control objects, and control logic.
