摘　　要：基于airpak软件对夏季柜式空调3种送风角度(水平角度、向上45°角和向上60°角)下办公室内热环境进行了三维数值模拟,得到3种工况下室内气流组织的流场和温度场分布特点.采用PMV、PPD和空气龄评价指标对室内热舒适性及空气品质进行对比分析.模拟结果表明在向上45°角送风的情况下,房间内各个工位总体热舒适性最好.The airpak software is used to conduct a three-dimensional numerical simulation to analyze the internal environment in summer in office room with a cabinet air conditioner with three air-supply angles （horizontal angle, upward angle of 45° and 60°） so as to get the characteristics of the flow field and temperature field under three different conditions of indoor air distribution. At the same time, this paper adopts the PMV, PPD and air age of evaluation methods to make a com- parative analysis of the indoor thermal comfort and air quality. The simulation results show that the overall thermal comfort in each tested position in the room is the best in the case when the air-supply angle is the upward angle of 45°.
