研究目的:目前在地铁设计中,设计的新风量及空调负荷基本按30年后的远期标准设计,这就造成了能 源的浪费,本文对此进行了分析,提出了一些改进方法,推荐一些新技术,以达到节能目的? 研究方法:(1)新风量按CO2浓度进行控制,新风单独处理;(2)空调负担由2组空调机分别控制,一组负担 固定的冷负荷,一组负担变动的冷负荷;(3)推荐有条件车站可采用冰蓄冷及地源热泵。 研究结论:(1)调节新风量降低了新风负荷;(2)对可变空调冷负荷进行调节,节约了能耗;(3)地下站采用冰 蓄冷系统可减少电容量40％,高架车站采用地源热泵机组比变冷媒流量多联机可减少电耗30％。
Research purposes: At present, in the subway design, the design of the new air volume and air conditioning load by 30 years after the long-term standard design, which resulted in a waste of energy, this article were analyzed, some improvements, some recommended New technologies to achieve the purpose of energy saving? Research methods: (1) fresh air volume control by CO2 concentration, fresh air separately; (2) air conditioning burden by the two groups of air conditioners were controlled, a group of fixed burden of cold load, a burden Changes in the cold load; (3) recommended conditions can be station ice storage and ground source heat pump. The conclusions are as follows: (1) Adjusting the fresh air flow reduces the fresh air load; (2) Adjusting the cooling load of the variable air conditioning saves energy; (3) Using ice storage system in the underground station can reduce the electric capacity by 40% Ground source heat pump unit than the refrigerant flow rate on the line to reduce power consumption by 30%.
