摘要：本次毕设课题的主要内容就是使用AIRPAK软件对铁路大型客站内的温度场、相对湿度场和人体舒适性及其空气品质进行模拟分析。这次是以沧州火车站为研究对象，通过Airpak对其气流组织进行数值模拟研究。分别详细分析不同送风方式下的气流组织分布情况，主要考虑的情况是上送上回和上送下回这两种送风形式。上送上回采用条缝送风形式，上送下回采用喷口送风形式。本文详细的分析了三种空调设计方案模拟计算出的结果，得出温度场和空气龄以及舒适度的分布特征，并比较了几种不同方案下的模拟结果，最后得出的结论是使用大喷口式的上送下回送风方式能够最好的解决大型客站人体舒适度问题。70043

Simulation and Analysis of Airflow Organization for Large Railway Passenger Station Based on Airpak

Abstract: The main content of this project is to use AIRPAK software on the railway large passenger station temperature field, relative humidity field and human comfort and air quality simulation analysis. This is based on the Cangzhou Railway Station as the research object, through Airpak its air flow organization numerical simulation study. Respectively, a detailed analysis of different air supply under the air flow distribution, the main consideration is sent on the back and send back to the two kinds of air supply form. Sent on the back of the use of a strip of air supply in the form of the next to send back to the use of jet air supply form. This paper analyzes the results of three air conditioning design schemes in detail, and obtains the distribution characteristics of temperature field and air age and comfort, and compares the simulation results under several different schemes. Finally, the conclusion is that Spouting on the delivery of the return air way to the best way to solve the large passenger station passenger comfort problems.
