摘　　要：地铁车站通风系统的设计是地铁环控系统的关键技术之一。本文首先针对哈尔滨的寒冷气候特点,在对哈尔滨地铁车站进行热负荷分析的基础上,提出了不同于其它地区的新的通风方案,使车站在不采用供暖系统条件下,就能满足乘客暂时舒适的要求。其次建立了地铁车站的三维模型,在标准湍流k-ε模型的基础上建立了通风系统的物理模型,采用CFD模拟软件来预测地铁车站内的气流场,并进行了比较分析。研究表明,该通风方案提供了一个相对舒适的乘车环境,对节省能源、保护环境有实际意义。The ventilation system was one of the key techniques in subway environment control. In this paper, according to the characteristics of cold climate, a novel ventilation system was firstly put forward based on the analysis of heat load distribution at the subway station in Harbin. Hence, themal comfort of passengers could be satistfied without the heating sysem. Secondly, a three dimensional model of the subway station was established, and a mathematical model for the novel ventilation system was developed based on the k-ε standard turbulence model. In addition, the software of computational fluid dynamics（CFD） was applied to predict the airflow field. The simulation results indicated that the temperature was acceptable. Therefore, the suggested novel ventilation system could be considered as a recommend strategy to obtain energy-saving and environmnet protection.
