Optimal Design and Application of Energy-saving Technology for Ventilation Air-conditioning in Subway Station

研究目的:地铁车站通风空调系统是地铁车站的能耗大户,有效降低车站通风空调设备能耗已成为车站通风空调专业设计的重点和难点。本文通过分析一个典型车站的空调负荷变化情况,来寻求一个降低车站通风空调设备能耗的有效途径。研究结论:根据车站通风空调系统能耗情况,采用节能优化设计流程,对车站逐时客流和空调负荷进行统计分析后,决定采用变频调节技术对通风空调设备进行调节,大大降低了能源消耗,节约了运营成本。相应的也可以减少变配电设备的装机容量,减少变配电所的机房面积,压缩车站的土建规模等。并为以后类似工程的节能设计提供借鉴作用。

Research purposes： Ventilation air - conditioning system is the main energy consumer in the subway station, so the effective reducing the energy consumption of ventilation air - conditioning becomes a key and difficult point for design of the ventilation air- conditioning in subway station. In this paper, the analyses changes of one typical air- conditioning load in the subway station are made for seeking an effective way to reduce the energy consumption the ventilation air - conditioning Research conclusions： Based on the energy consumption of ventilation air conditioning system equipped in subway station, the optimal design flow for energy - saving is analyzed. By analysis and statistics of passenger flow and load of air conditioning system of each hour, frequency conversion technology is determined to apply for regulating ventilation air-conditioning system. In this way, the energy consumption and operational cost can be reduced much, and the corresponding installed capacity of transformation and distribution equipments and the area of transformation and distribution equipment room can be lowered. Furthermore, the amount of the civil works of the station can be also decreased. This technology can be used in the similar works in the future.
