| 摘 要： | 利用CFD对室内存在不同形式内隔断的地板送风办公房间进行了数值模拟,研究其速度场、温度场及污染物浓度场;分析了内隔断的存在对室内空气品质的影响。研究结果表明,在办公桌靠近送风口侧设置的隔断,能够在一定程度上阻挡由送风口处送出的冷风直接抵达人体脚踝处,有助于改善人体脚寒的情况。但围合型隔断的存在将导致隔间内形成涡流,使人体周围的气流速度增大,并影响CO2的扩散,不利于其顺利排出。

| Abstract: | Investigated the effects of different forms of internal partitions in an office on the performance with underfloor ventilation system by CFD.The flow field,temperature field and pollutant distribution was studied.It indicated that the partitions set near the outlet side of the desk could block the supply air from sending directly arrived in human ankles to some extent,help to improve the situation of feet cold.However,surround close type partition would result in eddy current formed,which was unfavorable to the exclusion of CO2. |
