以上海地铁M7线肇嘉浜路站的通风空调设计实例为背景,从车站公共区空调冷负荷的计算入手,比较了屏蔽门系统和闭式系统空调负荷计算的区别及结果。并对这两种空调系统形式进行综合比选,特别着重进行了两者运行全年综合能耗的研究。只有因地制宜,根据地区的气候特点,空调期的长短、运力等具体情况进行全年能耗综合性分析,方能确定合理、节能的通风空调系统。最后以节能为主旨,提出了一种新思路,创造一种全年节能运行的空调系统。
Taking the design of ventilation and air conditioning in Zhaojiabang Road Station of M7 line of Shanghai Metro as an example, this paper starts with the calculation of air-conditioning cooling load in the public area of the station, and compares the difference between air-conditioning load calculation of screen door system and closed-system air-conditioning system. And the two air-conditioning system form a comprehensive comparison and selection, with particular emphasis on the operation of the year comprehensive energy consumption study. Only according to local conditions, according to the region’s climate characteristics, the length of the air-conditioning period, capacity and other specific circumstances of the annual comprehensive analysis of energy consumption in order to determine a reasonable and energy-saving ventilation and air conditioning system. Finally, taking energy-saving as the main idea, a new idea is put forward to create an air-conditioning system that runs year-round and energy-saving.
