地铁车站公共区双端与单端送风空调系统的研究及应用

RESEARCH AND APPLICATION OF DUAL END AND SINGLE END AIR CONDITIONING SYSTEMS IN PUBLIC AREAS OF SUBWAY STATIONS

厦门市轨道交通3号线翔安机场站、4号线翔安机场站公共区分别采用了双端送风空调系统和单端送风空调系统。从车站空间特点、冷负荷、投资、用地、能耗等方面进行了分析,结果显示4号线单端送风空调系统单位面积初投资额、系统能效比EER、风机单位风量耗功率Ws及水泵耗电输冷比ECR–a指标均优于3号线双端送风空调系统,3号线通风空调机房占地比例小于4号线,3号线通风空调机房土地利用程度更高。

This article combines the public areas of Xiang'an Airport Station on Line 3 and Xiang'an Airport Station on Line 4 of Xiamen Rail Transit,and analyzes the characteristics of station civil engineering,cooling load,space utilization,investment,energy consumption,etc.The results show that the initial investment per unit area,EER value,Ws and ECR-a indicators of the single end supply air conditioning system on Line 4 are better than those of the double end supply air conditioning system on Line 3.The proportion of land occupied by the ventilation and air conditioning room of Line 3 is smaller than that of Line 4,and the land use degree of the ventilation and air conditioning room of Line 3 is higher.
