通风的

The air conditioner forced draft fan ventilates the way to have longitudinal and the crosswise two kinds generally, the lateral ventilation the air current overflow sectional area is big, the wind speed is small, easy to create the big area the dead angle, but longitudinal ventilates the air current the overflow sectional area to be small, the wind speed is big, the dead angle area is very small.

冷风机通风方式一般有纵向和横向二种，横向通风的气流过流断面积大、风速小，容易造成较大面积的死角，而纵向通风气流的过流断面积小，风速大，死角面积很小。在使用条件许可的情况下，应该尽可能采用先进的纵向通风方式。
