深圳地铁一期工程创新节能技术

Innovative Energy-saving Technologies Applied in the First-Phase Project of Shenzhen Metro

阐述深圳地铁一期工程在节能方面所采用的新技术,并评估其节能效果。通过分析指出,地铁通风空调系统和电扶梯一直处于高能耗、高磨损、低效率的运行状态,在深圳等南方城市成为地铁运营耗能的主要设备。信息化变频空调通风系统节能技术通过变频调速,实现地铁车站空调通风系统低能耗、高效率的运行状态,节能超过70%。信息化全变频扶梯节能技术利用全变频控制技术能够进行无级调速的特性,为扶梯增加深度集成的监控技术,通过变频调速实现对扶梯的效率调控,使扶梯运行在节能状态,节能效果在30%以上。深圳地铁一期工程采用信息化节能技术后,其总能耗节电10%,年节电量超过1000万kWh。建议修订扶梯、空调、风机产品的国家标准。

Innovative energy-saving technologies applied in the first-phase project of Shenzhen metro are described with their energy-saving effect evaluated. It has been indicated through analysis that ventilation and air conditioning system as wen as escalators of metro were commisioned under high energy-consuming, high abrasion and low efficiency and that they have become the main high energy-consuming equipment in metro operation for Shenzhen and other southern cities of China. Informationized variable-frequency air conditioning and ventilation system by means of changing frequency and regulating speed helped to realize metro commisioning under the conditions of low energy-consumption and high efficiency with energy saved more than 70%. lnformationized full-variable-frequency escalators by means of stepless speed regulation to realize the efficiency control helped them to operate under energy-saving conditions with energy saved more than 30%. After the implementation of informationized energysaving technologies for the first-phase project of Shenzhen metro, electric energy-saving totaled 10% and annual electricity saving exceeded 10 million kWh. The national standards for escalators, air conditioners and ventilators are proposed to be modified.
