住宅新风系统风量分配装置压力平衡研究

为确保住宅建筑新风系统风量的合理分配,本文提出了一种新风系统设计方法,并通过计算流体力学模拟了一体积较小且带有六个出口的风量分配装置,以在不同位置设置不同长度的导流板的方式,得出在两侧设置长度为43 mm的导流板,在中心设置长度为44 mm导流板时,可以实现在一定风量范围内达到风量平衡且出口压力相等。

Study on Pressure Balance of Air Distribution Device in Residential Ventilation System

In order to ensure the reasonable distribution of air volume in the ventilation system of residential buildings,this paper presents a design method of ventilation system, and simulates a small air distribution device with six outlets which is calculated by computational fluid dynamics. By setting deflectors of different lengths at different positions, it can be concluded that when setting deflectors of 43 mm length at both sides and 44 mm length at the center, the air volume balance and can be achieved within a certain air volume range. At the same time,the outlets are under equal pressure.
