地铁通风空调系统的优化控制

摘要

In order to improve the system control capability in terms of energy conservation and emission reduction, the composition, principle and feature of metro air conditioning are briefly illustrated, the defect about routine scheme is pointed out, an optimum control about energy conservation is discussed by establishing a control model. Also, the energy conservation of heat elimination fan is introduced to implement the optimum schemes.%从节能的角度出发,提出优化地铁通风空调系统控制性能的重要意义.介绍了地铁车站通风空调系统的组成、原理、特征等,指出了常规的地铁通风空调系统控制方案的不足之处,提出了更为优化的变风量变流量控制模型.给出了地铁车站通风空调系统节能优化控制思路,并提出了一种优化控制方案.简述了车站排热风机的节能问题,并提出了优化解决方案:在综合监控的平台上,将车站的环境与设备监控系统和信号系统进行联动,控制排热风机变频器的转速,从而实现排热风机的节能减排.
