地铁A型车节能耐高温空调的开发

Development of energy-saving and anti-higher temperature air-conditioning for type A metro vehicle

介绍节能耐高温空调冷负荷和制冷系统匹配的计算方法,通过分析新风负荷和空气中CO2含量,详细分析制冷系统的设计和对新风量的控制方法,实现地铁A型车空调的节能运行,并解决在室外温度高于48℃时空调不能工作的问题。

The calculation method of matching cooling load and refrigeration system for energy-saving and anti-higher temperature air-conditioning is introduced. Through analyzing cooling load of fresh air and CO2 content in air, the refrigeration system design and control method of fresh air volume are analyzed. The energy-saving operation of the airconditioning for type A metro vehicle is realized, and it is solved that the air-conditioning still can operate when the outside temperature is over 48 ℃.
