在人工气候室内,对碰撞射流通风两种送风高度下的室内温度与气流速度进行了实测。结果表明:碰撞射流送风高度对室内温度竖直分布影响不大,但对紧贴地面的空气温度的衰减过程有明显影响;送风高度对室内气流分布有较大影响,增大送风高度可以减小地面附近气流的速度,但增大了离地面较远处的风速;由于送风高度较低时近风口处的空气温度较高,导致碰撞射流热风供暖时送风口越低,人体吹风感越小。
In the artificial climate chamber, the indoor temperature and the air velocity under two blast levels of collision jet were measured. The results show that the blast height of collision jet has little effect on the vertical distribution of indoor temperature, but has a significant effect on the attenuation of air temperature close to the ground. The height of blast air has a great influence on the distribution of indoor air flow, Can reduce the speed of air flow near the ground, but increases the speed of wind far away from the ground. Because of the high air temperature near the air outlet when the air supply height is low, the lower the air outlet when the collision jet hot air is heated, Smaller sense.
