广州地铁2号线风机控制的改进方案

An Improvement Method of Metro Ventilation Control in Guangzhou Metro Line 2

结合广州地铁 2号线通风空调系统中风机的控制设计 ,提出了在满足有关规范要求和通风空调工艺要求的前提下 ,简化风机控制的方案。即 :由原来的三级控制改为两级控制 ;风机的自动控制实现模式控制 ,主要用于地铁运营 ;风机的就地控制只实现单台设备的控制 ,取消了与风阀等设备的联锁控制。该方案有利于降低工程投资 。

Based on the control design of ventilation system in Guangzhou Metro Line 2, the author provides a simplified control method which could fulfill the requirements of ventilation system operation and its standardization. It is believed that the new design will reduce the investment and improve the reliability of the system.
