变风量空调系统静压重设控制的分析

Analysis of Static Pressure Reset Control in Variable Air Volume System

介绍了变风量空调系统的三种传统控制方式,并比较了各方法的优缺点。提出了一种新的变风量空调系统的控制方法——静压重设法,分析了具体的实现方法和相比于其他控制方式的优势,并对静压重设控制法的实施提出了一些建议。实践证明,控制系统设计简单,调试容易,节能潜力较大。

This paper introduced three methods of variable air volume（VAV） system：fixed static pressure method, variable static pressure method, and the total airflow rate method. The advantages and disadvantages of them were given. A new control strategy of static pressure reset control was proposed and the implementation for different types of systems and terminals was analysed. Some proposals of system implementation in real system were given. The practice proveds that the design of control system is simple, and the debugging is easy, which has a great proficiency of energy saving.
