在通风和空气调节领域中采用旋转射流(简称“旋流”)送风,已经在一些国家得到广泛应用。国外研制成多种类型的旋流送风口,成功地将旋流用于大空间送风、房间中部送风、地板送风和局部送风。由于旋流具有诱导比大和风速衰减快的特点,所以采用旋流送风可用大风量或高风速送风,以减少送风口的数量、简化送风系统和节省系统投资;更可用于直接向工作区送风、以提高送风的能量利用系数。我们为探讨高大空间空调采用旋流送风,开展了旋流送风口的试验研究工作。选
The use of rotating jets (“swirling”) in the field of ventilation and air conditioning has been widely used in some countries. Foreign developed into a variety of types of swirl air outlet, successfully used for large-scale air circulation, air in the middle of the room, floor air supply and local air supply. Since the swirling flow has the characteristics of large induction ratio and fast attenuation of wind speed, the cyclone air supply can be used to supply air with large air volume or high wind speed to reduce the number of air outlets, simplify the air supply system and save system investment; it can also be used for direct work. District air supply to increase the energy utilization factor of the air supply. In order to investigate the use of swirling air supply for high-spatial air conditioning, we conducted a pilot study of a cyclone air supply. selected
