【摘要】：近年来,随着我国国家经济的迅速增长、社会的不断发展以及广大老百姓生活质量和标准的提升,汽车拥有数量迅速增加，在很多的城市,出现了停车难的问题并且很严重。目前，不管居住性质的建筑还是商业性质的建筑都已经把停车位作为一个重要指标，在每个工程项目正式实施前都要审核这一指标。而地上停车位已经不能保证正常的使用要求，在商业建筑和住宅类型的建筑中为了满足正常的用地需要并解决停车位置的需求，因此在这些建筑中修建了很多的地下车库。和地上建筑相比较，地下车库具有高度密闭性，从而使流动或者停放的汽车排出的废气和发生火灾时产生的高温烟气很难自行扩散，所以在车库内必须设置正常的通风换气和火灾排烟系统。地下车库的通风是为了把车库内停放的汽车所产生的对人体有危害的气体及时排除，并送入室外品质良好的空气使污染物浓度降低到国家规定的范围内；车库排烟是为了发生火灾时能够迅速及时的排除产生的高温烟气并阻止烟气的迅速蔓延，确保车库内所有人员的身体以及物品安全，减少因火灾而导致的死亡和受伤。所以怎样更好的处理地下车库的通风及排烟设计中出现的问题，减少项目投资和运行费用，就成为广大科研人员和设计人员值得研究、思考的问题。本文研究了地下车库通风排烟系统的原理、计算方法以及工程设计中常用的系统形式，讨论了国家规范中对于地下车库通风与排烟系统的相关规定及存在的问题，并以延安市政协地下车库通风与排烟系统的设计方案为例进行实例分析，进一步优化了设计方案，通过对具体问题的分析与计算，得到一套合理与经济性兼具的地下车库通风与排烟系统设计方案。
[Abstract]:In recent years, with the rapid growth of China's national economy, the continuous development of society and the improvement of the quality of life and standards of the general public, the number of cars has increased rapidly, in many cities. There is a parking problem and it is very serious. At present, both residential and commercial buildings have used parking space as an important indicator. This indicator must be reviewed before each project is formally implemented. However, the above ground parking space can no longer guarantee normal usage requirements, in order to meet normal land needs and address parking space needs in commercial and residential buildings, So there are a lot of underground garages built in these buildings. Compared with the above ground buildings, underground garages are highly airtight, which makes it difficult for mobile or parked cars to emit exhaust gas and for high temperature smoke from fires to spread on their own. Therefore, normal ventilation and smoke removal systems must be installed in the garage. The ventilation in the underground garage is to remove the harmful gas produced by the parked car in the garage in a timely manner. And into the outdoor air of good quality to reduce the concentration of pollutants within the limits of the state; garage smoke discharge is to quickly and timely remove the high temperature smoke generated in case of fire and prevent the rapid spread of smoke, To ensure the safety of all persons in the garage and reduce the number of deaths and injuries caused by fire. So how to better deal with the problems in ventilation and smoke exhaust design of underground garage, and reduce project investment and operating costs, It has become a problem worth studying and thinking about by researchers and designers. In this paper, the principle, calculation method and common system form of underground garage ventilation and smoke exhaust system are studied, and the relevant regulations and existing problems of underground garage ventilation and smoke exhaust system in national code are discussed. Taking the design scheme of the ventilation and smoke exhaust system of the CPPCC underground garage in Yan'an as an example, the design scheme is further optimized, and the concrete problems are analyzed and calculated. A reasonable and economical design scheme of ventilation and smoke exhaust system for underground garage is obtained.
