寒冷地区地铁通风空调系统节能研究

Study on energy-saving measures in subway HVAC system in cold regions

以哈尔滨地铁通风系统为例研究寒冷地区的节能措施，对北方寒冷地区地铁环境控制系统的能耗情况及节能潜力进行了分析计算，并根据分析提出了寒冷地区通风空调系统的节能措施，能耗计算结果显示可实现节能25％～40％．结果表明：冬季工况为寒冷地区节能重点，充分回收地铁车站中的余热、根据负荷变化考虑通风方案、设备管理用房分区控制等措施可实现更大程度的节能．

In order to study energy saving measures of subway HVAC system in cold regions, energy consumption and energy saving potential of Harbin subway environment control system was analyzed as an example. Several energy saving measures were brought forward. The energy consumption analysis results show that it can save 25% -40% of energy with those measures. Thus, it can be concluded that the energy saving measures in winter is the key measures in cold regions, and it can achieve a great degree of energy saving by using waste heat recovery in subway stations, air volume varying with the load, and zoning in management and equipment rooms.
