某高大空间宴会厅空调气流组织的模拟研究

Numerical Simulation of Air Distribution in a Large Space Banquet Hall

结合上海某酒店宴会厅夏季空调运行情况,利用Airpak软件对宴会厅内部的气流进行模拟研究。在现有的上送上回的气流组织形式上,结合宴会厅实际使用情况,提出了上送下回的气流组织形式,并对这两种气流组织效果分别进行模拟。通过研究发现,当采用上送下回风的气流组织形式时,宴会厅内部的温度场与速度场更均匀,为高大空间宴会厅的空调效果的改善提供了参考。依据模拟优化结果,对该酒店宴会厅提出了可行的节能改造方案。

Combining with the air conditioning situation of a large space banquet hall in a Shanghai hotel,the software Airpak is used to simulate the internal air distribution in the large space banquet hall.The banquet hall now adopts ceiling air supply and ceiling air return,based on the actual usage,the ceiling air supply and below return is suggested for it.These two air distributions are simulated in this paper,respectively.The results of the simulations show that the temperature and velocity field of the banquet hall is more uniform when the hall adopts ceiling air supply and below return.This paper also provides a reference for the choice of air distribution in large space banquet halls.According to the results of simulation and optimization,some feasible energy-saving programs are proposed for the banquet hall in the hotel.
