摘　　要：为进一步挖掘城市轨道交通地下车站公共区通风空调系统的节能潜力,解决传统全空气空调系统输配能耗高、管道占用空间大等方面的不足,在长沙市轨道交通6号线工程中应用了分散式空调系统。通过对地下标准车站公共区采用全空气系统、分散式空调系统两种不同的通风空调方案进行技术性和经济性的对比分析,得到结论如下:与全空气系统相比,分散式空调系统设备投资相对节省、土建投资相当、运行费用相对节省。从减小风机电耗、满足末端调控角度上对比,分散式空调系统更具优势。In order to further tap into the energy saving potential of the ventilation and air-conditioning system in the public area of urban rail transit underground stations,and to solve the shortcomings of the conventional all-air system such as high energy consumption and large space occupied by pipes,a distributed air-conditioning system is applied in the project of Changsha Rail Transit Line 6.Through technical and economical comparison and analysis of applying two different ventilation and air-conditioning scheme,all-air system and distributed air-conditioning system,in underground station public area,conclusion is arrived to as follows:compared with all-air system,distributed air-conditioning system has relatively less investment in equipment,similar in civil engineering,and less in operating cost.From the perspective of reducing fan power consumption and serving terminal control,distributed air-conditioning system has more advantages.
