摘　　要：为研究不同形式的风口对酒店高大空间空调气流组织的影响,本文以福建省厦门市某酒店多功能厅为模型,利用气流组织模拟方法对其夏季室内工况分别采用球形喷口和双层百叶风口进行模拟,得到室内速度场、温度场、预计平均热感觉指数、预计不满意者的百分数。结果表明:采用球形喷口时,2 m以下人员活动区域水平温度、速度分布均较为均匀。基于预计平均热感指数、预计不满意者的百分数的热环境数值预测和评价,可得出球形喷口的热舒适性与百叶风口相当。In order to study the influence of different forms of tuyeres on the air distribution of air conditioning in large spaces of hotels,taking a multi-functional hall of a hotel in Xiamen as a model,this paper uses the air distribu⁃tion simulation method to simulate its indoor working conditions in summer by using spherical nozzle and double-lay⁃er louver tuyere respectively,and obtains the indoor velocity field,temperature field,expected average thermal sensa⁃tion index and the percentage of dissatisfied people.The results show that when the spherical nozzle is used,the hor⁃izontal temperature and velocity distribution in the personnel activity area below 2 m are more uniform.Based on the numerical prediction and evaluation of thermal environment based on PMV,PPD,it can be concluded that the thermal comfort of spherical nozzle is equivalent to that of louver vent.There is little difference in air age between the two.The spherical nozzle is adopted,and the air quality in the banquet hall is relatively good.
