摘要： 火车站是典型的大空间建筑，气流组织复杂，合理设计空调系统的送排风形式、实现对气流有效控制的难度远远高于普通建筑。通常，火车站人员密集，喷口送风是常用的方式，用侧喷口送风射流覆盖人员区。喷口送风系统容易布置，只要气流控制得当就可以起到好的效果。本次研究课题以建筑模拟软件AIRPAK为工具，学习建筑室内气流组织的研究方法；通过该软件建立铁路大型客站建筑模型，模拟关系到建筑物室气流组织的各种技术参数情况，分析各个参数对室内空调设计和空气品质的影响。从室内温度、湿度、压力等热湿物理环境等方面入手，分析气流组织与空调设计和室内空气品质之间的关系，从而改善影响室内空气品质并指导空调系统的设计，提出铁路大型客站气流组织和空调设计改进的方向和潜力。由于实际建筑模型比较复杂在建模中做了简化处理。在查阅各种火车站空调的设计之后对中送上回的送风方式进行模拟，模拟结果表明中送上回的气流组织方式适合火车站空调系统。22224

Based on Airpak large railway station airflow organization simulation and analysis
Abstract: The railway station is a typical large space building, the air distribution is complex so the difficulty that reasonable design of air conditioning system to exhaust form, realize effective control of airflow is much higher difficulty han ordinary buildings. Usually, the railway station was crowded; nozzle air supply is a common way, cover personnel with lateral nozzle air supply jet area. Nozzle air supply system is easy to decorate, as long as proper airflow control can play a good effect. This research topic for building simulation software AIRPAK tools, learning methods of building indoor air distribution; Railway station buildings model is established by the software, the simulation is related to building room air distribution of various technical parameters, analysis of various parameters on the influence of indoor air conditioning design and air quality. From the indoor temperature, humidity, pressure hot wet
physical environment and other aspects, such as analysis of air distribution and air conditioning design and the relationship between the indoor air quality, to improve indoor air quality and guide the design of the air conditioning system, puts forward the railway large district air distribution and air conditioning design direction and the potential for improvement. Actual building model is complicated so in modeling model is simplified.After refer to all kinds of railway station air conditioning, the form which Air blows out from the top and returns from bottom is suitable for large space building, the simulation results show that form of air distribution in the air conditioning system suit the railway station.
