本文介绍的送风口,是向室内供给有较大速度的主气流,并可随时间改变这个主流的方向,因此可作为夏季室温变动的补偿手段。称这种型式的送风口为间歇气流型送风口。 1.间歇气流舒适感与气流速度的关系可见图1。若室内设计温度为28℃,只要气流速度为0.75米/秒,仍属于舒适范围。作为节能方法之一所议的改变夏季的设计室温,必须用某些手段作为创造舒适感的补偿。手段之一是研究增加气流速度。
The air outlet introduced in this paper is to supply the main airstream with a large speed to the room, and can change the direction of this mainstream over time, so it can be used as a compensation method for the room temperature change in summer. This type of air outlet is called an intermittent airflow air outlet. 1. Intermittent airflow comfort and airflow velocity can be seen in Figure 1. If the interior design temperature is 28°C, as long as the airflow rate is 0.75 m/s, it is still within the comfort zone. As one of the energy-saving methods discussed, changing the design room temperature in the summer must use certain means as compensation for creating comfort. One of the means is to study increasing the air speed.
