轨道交通空调中风系统与水系统协调控制研究

Study on the coordination control between the air conditioning stroke system and the water system in rail transportation

针对目前中央空调节能控制中对风系统与水系统协调控制研究的空白,本文以轨道交通环境控制系统为研究对象,通过分析空气处理机组的送风风量与流过表冷器的冷冻水流量对空气处理机组输出冷量的影响规律,提出了基于最优工作点的送风风量与冷冻水流量的协调控制方法,为地铁空调系统在部分负荷下风系统与水系统的控制策略提供参考。

Aiming to fill the gap of coordinated control with ventilation system and water system on the present energy-saving control of central air condition,in this paper,taking the rail traffic environment control system as the research object,to analysis the influence rules of the cold output of air processor which been effect with the air volume of air processor and the cooling water flow through the cooler,and this article propose a coordination control method it based on the optimal point for the air quantity and flow of cooling water,and it could provide reference in the control strategy of low load ventilation system and water system for subway station air condition.
