亚洲金融大厦标准办公单元变风量空调系统自控策略分析
摘要：重点分析了幕墙侧风机盘管结合变风量空调系统在主风管变静压调节过程中有效实现整体控制的运行策略。将幕墙侧风机盘管纳入变风量空调自控系统进行整体控制，避免了以往项目中同一区域2种系统独立控制时容易产生的温度失调问题，同时，采用静压设定值定步长调整法，通过简单有效的控制逻辑实现了主风管变静压调节。经过冬、夏季的运行测试，结果显示上述空调自控系统达到了变静压调节的要求，并且实现了幕墙侧风机盘管与变风量空调系统的整体控制。

Analysis on automatic control strategy of variable air volume air conditioning system in standard office units of Asia Finance Building
Abstract: This paper focuses on the analysis of the operation strategy of the curtain wall side fan-coil unit combined with the variable air volume(VAV) air conditioning system in the main air duct variable static pressure adjustment process to effectively realize the overall control. The control of curtain wall side fan-coil unit is incorporated into the VAV air conditioning automatic control system for overall control, which avoids the temperature imbalance easily caused by the independent control of two systems in the same area in the past projects. At the same time, the static pressure setting value constant step adjustment method is adopted to realize the variable static pressure regulation of main air duct through simple and effective control logic. After a winter and summer operation test, the results show that the air conditioning automatic control system meets the requirements of variable static pressure adjustment, and realizes the overall control of the curtain wall side fan-coil unit and the VAV air conditioning system.
