| 摘 要： | 针对一个采用置换式诱导器系统的典型办公室,建立了物理模型及数学模型。利用FLUENT软件,以计算流体力学与传热学为基础,采用κ-ε湍流模型结合壁面函数法对室内的气流组织进行了模拟计算,得到了不同工况下的室内温度场、速度场,并分析了不同的送风温度对室内气流组织的影响,得出了置换式诱导器系统可以在比传统置换通风系统节能基础上提供更良好的热舒适环境的结论。

| Abstract: | The physical and mathematical models for an assembly room with displacement idu ventilation system were established.Based on the computational fluid dynamics and heat transfer theory,numerical simulation was made for indoor airflow with the software CFD using the κ-ε turbulent model combined with the standard wall function method.The temperature field and velocity field under different working conditions were obtained.This paper analyzed the indoor airflow under different temperature of air supply,and drew the conclusion that displacement idu ventilation system not only saves energy but also provides comfortable thermal environment compared with tranditional displacement ventilation system. |
