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。
The ventilation and air-conditioning system of Shenzhen Metro Station accounts for about 65% of the low-voltage electricity consumption of the station. Because the design of the subway system is calculated according to the hottest and long-term peak operating conditions, with 10% ~ 20% of design remaining Volume, and the current passenger flow is far below the design rating, ventilation and air conditioning equipment designed to work under rated conditions, the existence of “” horse car "phenomenon, therefore, energy saving potential is very large. The most effective energy-saving measures is to use the inverter to regulate the flow, air volume, frequency converter energy-saving rate of 20% to 50%. Combined with the characteristics of the first phase of the project in Shenzhen Metro loop control system, energy-saving space of the loop control system be analyzed.
