            摘要:

            地铁环控系统中车站公共区环控系统主要有空调系统和通风系统2种系统形式,目前对采用空调系统的研究较多,而对采用通风系统的研究较少。我国东北、西北等属于严寒地区,公共区普遍采用通风系统,已通车运营的地铁项目存在冬季车站内温度不达标的情况。以呼和浩特市地铁环控系统设计方案为例,根据对此类地区已通车项目的调研情况,利用CFDSES等模拟计算软件进行了研究,提出了适用于严寒地区的环控系统设计方案。

            Abstract:

             There are two types of underground railway environmental control system in public area including air conditioning systems and ventilation systems. At present, many researches focus on the use of air conditioning systems, but few studies on the use of ventilation systems. The northeast and northwest regions of China locate in the severe cold zone. The ventilation system is widely used in public areas. The current underground railway projects putting into operation have the problem that the indoor temperature of the station is not satisfied with the requirements of standard in winter. Taking a design scheme of the underground railway environmental control system of Hohhot as an example, based on the investigation in severe cold zone, carries out a research by the simulation calculation software such as CFD and SES, and proposes a design scheme of the environmental control system suitable for severe cold zone.
