Floor-standing air conditioners (FSACs) have been widely used in civil and office buildings due to their high cooling capacity and easy installation in recent years. Increasing attention has been given to reducing the draft sensation of FSACs. This study introduces a new form of smart terminal for air conditioners that can be automatically adjusted by identifying the positions of humans in the room. The smart terminal has certain practical value given its simple structure and relatively low cost. A target air supply evaluation index for regional thermal comfort evaluation named the air velocity target value is proposed. A computational fluid dynamics model is established, and an orthogonal experiment of 4 factors and 4 levels is designed. The optimal parameters of the terminal are further determined through a series of optimization steps. The effect of the smart terminal is validated with numerical simulation and experimental measures, and the local velocities of the occupied zone are mostly below 0.3 m/s, showing that the draft level in the room is acceptable. Compared with the case of an air conditioner only, the air velocity target value of the room with a smart terminal decreases by 21.3%–63.3%. Compared with other existing manually controlled terminals purchased online, the smart terminal satisfies the minimum air velocity target value in the occupied zone. This study can also be used to guide the positioning and setting of air supplies for different positions of humans in a room under other air distributions.

近年来，落地式空调（FSAC）因其制冷量大、安装方便等特点，在民用和办公建筑中得到了广泛的应用。人们越来越关注减少 FSAC 的草案感觉。本研究介绍了一种新形式的空调智能终端，可以通过识别房间内人的位置来自动调整。智能终端结构简单，成本较低，具有一定的实用价值。提出了一种用于区域热舒适性评价的目标送风评价指标，即风速目标值。建立了计算流体动力学模型，设计了4因素4水平正交试验。通过一系列优化步骤进一步确定终端的最优参数。通过数值模拟和实验措施验证了智能终端的效果，占用区域的局部速度大多在0.3 m/s以下，表明房间内的吃水水平是可以接受的。与仅安装空调的情况相比，安装智能终端的房间的风速目标值降低了21.3%~63.3%。与现有网上购买的其他手动控制终端相比，智能终端满足占用区域的最小风速目标值。该研究还可用于指导在其他空气分布下的房间内不同位置的人的空气供应的定位和设置。表明房间内的气流水平是可以接受的。与仅安装空调的情况相比，安装智能终端的房间的风速目标值降低了21.3%~63.3%。与现有网上购买的其他手动控制终端相比，智能终端满足占用区域的最小风速目标值。该研究还可用于指导在其他空气分布下的房间内不同位置的人的空气供应的定位和设置。表明房间内的气流水平是可以接受的。与仅安装空调的情况相比，安装智能终端的房间的风速目标值降低了21.3%~63.3%。与现有网上购买的其他手动控制终端相比，智能终端满足占用区域的最小风速目标值。该研究还可用于指导在其他空气分布下的房间内不同位置的人的空气供应的定位和设置。智能终端满足占用区域的最小风速目标值。该研究还可用于指导在其他空气分布下的房间内不同位置的人的空气供应的定位和设置。智能终端满足占用区域的最小风速目标值。该研究还可用于指导在其他空气分布下的房间内不同位置的人的空气供应的定位和设置。
