为了探索家用壁挂式空调器安装位置、送风角度、送风温度、风速对室内气流组织的影响,找出提高室内舒适性的方法,采用 CFD 数值模拟的方法,对某住宅卧室内的壁挂式空调器运行时在各种安装条件下的室内气流组织进行数值模拟。通过对模拟得到的室内温度场和速度场的分析,得出在满足室内温度要求(26℃)的前提下,当空调器的送风角度45°,送风速度4.5 m/ s,安装高度2.2 m 时,房间内的温度场和速度场效果最佳,且满足人体舒适性的要求。

In order to explore the influence of installation position, angle of sending wind, air tem-perature, wind speed of household hanging air conditioner on indoor air flow and to find out ways to improve indoor comfort, the CFD was used to simulate the air flow from a household air conditioner hanging in a residential bedroom under a variety of installation conditions. Based on the analysis on the simulated indoor temperature field and velocity field, under a prerequisite of air temperature (26 ℃), when the angle of sending wind of the air conditioner is 45°, wind speed is 4. 5m/ s and the mounting height is 2. 2 m, the temperature field and velocity field in the room will be the best and satisfy the human requirement of comfort.
