新的旋流送风是“由上向下”送风方式的一种演变形式,其特点是: 送风由天花板向下或沿着天花板下水平吹入。它在房间中造成一个旋流,这个旋流的核心是一个不运动的死区。这个死区的空气由侧面被抽吸出(图1)。这时空气粒子在核心区域画出一条对数螺旋线。此方法曾做过模型试验,并证实在实际上是可行的。其优点是:1.能够形成一个布满房间的气流 The new swirling air supply is an evolution of the “down-and-down” air supply method, which is characterized by: The supply air is blown down from the ceiling or horizontally along the ceiling. It creates a swirl in the room. The core of this swirl is a dead zone that is not moving. The dead air is drawn from the side (Figure 1). At this time, air particles draw a logarithmic spiral in the core area. This method has been model tested and confirmed that it is actually feasible. Its advantages are: 1. It can form a full room air flow
