浅谈地铁空调系统的风水联动

Discussion on Fengshui Linkage of Subway Air Conditioning System

随着地铁行业的发展,运营线路、车站不断增多,机电设备也随之增加。机电系统中通风空调专业作为城市轨道交通地下车站的“呼吸系统”,是保证地铁运营的先决条件。通风空调系统关注的重点是洁净和节能,洁净度可以通过除尘、空气净化等设备达到要求,风水联动控制达到节能效果是我们文中讨论的重点。在轨道交通行业中,通风空调系统约占地铁能耗的30%,仅次于牵引供电系统。地铁通风空调系统的设备一般按照远期高峰运行情况进行配置,因此设备选型有较大的富余量。在满足设备正常运转、乘客舒适度的前提下,如何实现节能降耗是我们探讨的主题。为了使通风空调系统实现有效的节能,需要不断地探索、实践和归纳。通过对地铁通风空调系统节能关键点进行分析,结合对不同工况运转条件实践后的总结,在地铁通风空调系统中归纳形成完整的逻辑控制应用,实现焓值控制和群控控制的有效结合。

With the development of the subway industry,the number of operating lines and stations is increasing,and the number of electromechanical equipment is also increasing.As the"breathing system"of the underground station of urban rail transit,the ventilation and air conditioning specialty in the electromechanical system is the prerequisite to ensure the subway operation.The focus of ventilation and air conditioning system is clean and energy-saving.The cleanliness can be achieved by dust removal,air purification and other equipment.The energy-saving effect of wind water linkage control is the focus of our discussion.In the rail transit industry,ventilation and air conditioning system accounts for about 30%of subway energy consumption,second only to traction power supply system.The equipment of subway ventilation and air conditioning system is generally configured according to the long-term peak operation,so there is a large amount of redundancy in equipment selection.Under the premise of meeting the normal operation of equipment and passenger comfort,how to achieve energy saving and consumption reduction is the theme of our discussion.In order to realize the effective energy saving of ventilation and air conditioning system,we need to constantly explore,practice and summarize.Based on the analysis of the key points of energy saving in subway ventilation and air conditioning system,combined with the summary of the practice of different operating conditions,a complete logic control application is formed in subway ventilation and air conditioning system,so as to realize the effective combination of enthalpy control and group control.
