摘　　要：为了探索太阳辐射与通风方式共同作用下室内人体舒适度体验及空气品质优劣,以某自习室作为研究对象,对太阳辐射下自习室内采用不同通风方式时的运行特点及效果进行了模拟分析.主要以CFD流体力学为理论基础,利用Fluent软件对混合通风、地板送风及置换通风3种不同通风方式进行模拟计算,探索太阳辐射下室内温度场与速度场的变化规律、不同辐射强度下室内温度的变化特性以及污染物NO2进入室内后的扩散轨迹及浓度分布.研究结果表明:自习室内采用地板送风方式能够营造舒适的室内人居环境,是一种舒适高效的通风方式.In order to explore the indoor human comfort experience and air quality under the combined effect of solar radiation and ventilation,a study room was taken as the research object to simulate and analyze the operating characteristics and effects of different ventilation modes in the study room under solar radiation.On the theoretical basis of CFD fluid mechanics,Fluent software was used to simulate and calculate three different ventilation modes,namely mixed ventilation,floor air supply and displacement ventilation,to explore the change law of indoor temperature field and velocity field under solar radiation,the change characteristics of indoor temperature under different radiation intensification,and the diffusion trajectory and concentration distribution of pollutant NO 2 after it entered the room.The results show that the floor air supply method could create a comfortable indoor living environment and is a comfortable and efficient ventilation method.
