变频节能技术在地铁车站通风空调系统应用

地铁车站空调通风系统是地铁车站设备的耗能大户，其耗电量约占地铁车站设备总用电量的50％左右。空调通风设备的选型是根据车站最大负荷确定的，而绝大多数时间空调通风设备均在选型负荷60％的情况下运行。因此采用比较经济合理的通风空调设备能更好的节约能源。

Application of frequency conversion energy-saving technology in ventilation and air conditioning system of subway station

The air conditioning and ventilation system of subway station is the major energy consuming equipment in metro station , and its power consumption is about 50%of the total electricity use of the subway station equipment .Selection of air conditioning and ventilation equipment is determined ac-cording to the maximum load in the station , but most air conditioning and ventilation equipment are operating using 60%load of selected air conditioning and ventilation equipment for most of the time . Therefore it can save more energy to use more economic and reasonable ventilation and air condition-ing equipment .
