日本改建地铁车站空调设施的首例是大阪市地铁客流量最大的梅田车站。大阪市地铁自四十年代开通以来至今已拥有6条线路,形成网状结构,共计99.1km,设有93座车站,日客运量已达240万人次,承担着城市交通大动脉的使命。回顾大阪市地铁运行初期由于运输量小、产热量低,又不断向周围地层传热,因此一般的机械通风已足以满足乘客对地铁环境要求,然而随着输送能力的增长,列车和乘客发热量增大,温度逐年上升,至五十年代中期,特别当夏季高峰交通小时地铁几乎成了“不快感”的代名词。为了
The first case of air-conditioning facilities in Japan’s rebuilt subway station is Umeda Station, which has the largest passenger flow in Osaka Metro. Since its opening in the 1940s, Osaka Subway has six lines and has a mesh structure with a total area of 99.1km. With 93 stations, the number of passengers per day has reached 2.4 million. It undertakes the mission of the urban traffic arteries. Recalling that in the early stage of Osaka City’s subway operation, due to the small amount of transportation and low heat production, heat transfer to surrounding formations continued. Therefore, general mechanical ventilation was sufficient to meet passenger demand for subway environment. However, with the increase of transportation capacity, the heat of train and passengers Increased and the temperature increased year by year. By the mid-1950s, especially when traffic peaked in summer, the subway almost became synonymous with “displeasure.” in order to
