本文介绍了利用风机气流站（FAS）实现变风量（VAV）系统的两种送风机速度控制方法。在第一种方法中，控制送风机速度以保持优化的系统阻力（S），该阻力是根据测量的风机头和气流计算的。在第二种方法中，控制送风机速度以保持风管静压设定点，该设定点根据FAS测量的气流比重置。与使用固定管道静压设定点的传统送风机速度控制相比，这两种方法都可以使接线盒打开得更多。这些创新方法可应用于带有直接数字控制（DDC）或气动控制接线盒的系统。实例研究表明，新的控制方法可以显著地节约风机电源，提高风机效率。 单位:双引文:ASHRAE交易，第114卷，pt。2008年1月1日，纽约

Two supply fan speed control methods for a variable airflow volume (VAV) system using the fan airflow station (FAS) are introduced in this paper. In the first method, the supply fan speed is controlled to maintain an optimized system resistance (S), which is calculated based on the measured fan head, and airflow. In the second method, the supply fan speed is controlled to maintain the duct static pressure set point, which is reset based on the airflow ratio measured by the FAS. Both methods can make the terminal box open more compared with the conventional supply fan speed control using a fixed duct static pressure set point. These innovative methods can be applied to systems with either direct digital control (DDC) or pneumatic control terminal boxes. The case studies show that the new control methods can significantly save supply fan power and improve fan efficiency.Units: Dual
