地铁通风系统的主要任务是在正常或紧急工况下提供必要新风量,藉以控制区间隧道空气温度和周围土壤温度。就通风系统而言,控制区间隧道温度是短期行为,而控制其周围土壤温度是长期行为,关键是二者之间是否存在矛盾。本文就此问题根据国内外地铁实测数据进行消化、分析和综合,以四季分明(3个月夏季、3个月冬季、6个月过渡季)地区单线交通地铁区间隧道情况为例,对夏季、冬季和过渡季通风系统运作进行粗浅分析,供同行们共同讨论。
The main task of the metro ventilation system is to provide the necessary fresh air flow in normal or emergency conditions to control the air temperature in the inter-section tunnel and the surrounding soil temperature. In the case of ventilation systems, the control of the tunnel temperature is a short-term behavior, and controlling the temperature of the surrounding soil is a long-term behavior, the key being whether there is a conflict between the two. In this paper, based on the data measured at home and abroad subway digestion, analysis and synthesis, with four distinct seasons (three months in summer, three months in winter, six months transitional quarter) single-lane subway traffic tunnel as an example, summer, winter And the interim season ventilation system to conduct a superficial analysis for colleagues to discuss.
