Application of arc-shaped deflector in ventilation and air conditioning

提出将弧形导流板应用于射流碰撞类通风以改善室内流场,从而达到节能舒适的目的。利用数值模拟的方法对弧形导流板改善室内流场的效果展开研究,并分析了导流板尺寸、形状、位置以及送风参数对其产生的影响。结果表明,在竖壁贴附送风的应用中,合理引入弧形导流板可以消除房间角落旋涡,减少超过28%的动能损失,并且延长了竖壁贴附送风的作用范围。

Arc-shaped deflector is proposed to optimize the flow field in jet impingement ventilation and achieve the purpose of energy saving and human thermal comfort.The effect of the arc-shaped deflector on optimizing the flow field is studied by numerical simulation method.The influence of the size,shape,position of the deflector and the air supply parameters is analyzed.The results show that the reasonable application of arc-shaped deflector can eliminate the vortex in the corner of the room,reduce the kinetic energy loss by more than 28%,and extend the scope of the air curtain ventilation.
