深圳地铁车站环控系统节能分析

Energy Efficiency Analysis for the Environment Controller System in Shenzhen Metro

深圳地铁车站通风空调系统占车站低压用电量的65%左右,由于地铁环控系统的设计是根据天气最热、远期高峰运营条件来计算的,并且留有10%～20%的设计余量,而目前的客流量远未达到设计额定值,通风空调设备按设计额定工况运行,存在"大马拉小车"的现象,因此,节能潜力非常大。最有效的节能措施就是采用变频器来调节流量、风量,应用变频器节电率为20%～50%。结合深圳地铁一期工程环控系统的特点,对环控系统的节能空间予以分析。

Power consumption of the ventilation and air conditioning system in Shenzhen metro station takes 65% of the total electrical energy east. Ventilation system design was based on the hottest weather and the future operating conditions at its peak with 10%-20% design margin, The ventilation system runs at its rated capacity, but the passenger flow volume is far from the design rating, so it has a great potential for energy efficieney. The most effective solution is to use inverter to control the air flow volume. The adoption of inverter would be able to save energy by 20%-50%. To take the first phase project of the Sherazhen metro as an example, energy efficiency space of the environment controller system was analyzed.
