摘　　要：针对一个采用置换通风系统的典型办公室,建立了物理模型及数学模型,采用k-ε湍流模型结合壁面函数法对空调室内的湍流流动进行描述,采用有限容积法对控制方程进行离散,利用AirPak软件对不同工况下室内温度场、速度场进行了模拟计算,分析了送风温度、送风速度、送风口位置等因素对室内气流组织的影响。The physical and mathematical model for an assembly room with displacement ventilation system is established. Turbulent flow in the aircondition room is described by using the standard κ-ε turbulence model linked with the wall function, and the finite volume method is used to discrete the governing equation. According to different working conditions, the velocity field and temperature field in the room are simulated by the software AirPak. The impacts of air-in temperature, velocity and different location of the diffuser on indoor air quality are analyzed.
