碰撞射流在航站楼的应用及与分层空调的比较

Application of Impinging Jet Ventilation in Aviation Building and Contrast with Stratified Air Conditioning

碰撞射流通风是近年提出的一种新通风方式,有较好的应用前景。本文将其应用于航站楼类高大空间建筑,模拟分析室内气流组织及舒适性,并与分层空调通风方式进行对比。结果表明,两种通风方式均能满足工作区的设计温度;若采用碰撞射流通风方式,可以缓解工作区的吹冷风感,使得气流在同一水平面的分布更均匀,同时提高室内的热通风效率,更好地消除热负荷。

Impinging jet ventilation is a new and quite potential type of ventilation mode, which is now presented in an aviation building to investigate the air distribution and indoor comfortableness, and compared with the stratified air conditioning mode. Results show that, two type ventilation modes both satisfied the indoor temperature, while under the mode of impinging jet ventilation, cold feeling is weaken in the work area, and air distribution is more uniform along the same plane, also the ventilation efficiency is improved to eliminate the heat load more efficiently.
