不同送风速度下碰撞射流供热特性的实验研究

Experimental Research on the Characteristic of Impinging Jet Ventilation System of Heating under Different Air Velocity

本文利用实验的方法对碰撞射流通风供热系统的特性进行了分析,通过设置对比实验,对碰撞射流通风方式下不同的送风速度进行实验,实验结果表明,在通常允许的范围内,送风速度越高,室内温度分布越均匀,有效风感温度越满足1.7<△ET<+1.1,越有利于提高热风利用率,为碰撞射流通风广泛应用提供良好的理论基础。

To experiment by setting the comparative experiments under different air velocity, the characteristics of impinging jet ventilation system of heating were experimentally studied. The experimental results show that in the normally allowable range, the higher the air velocity, the more uniform temperature distribution, and the more the effective air temperature to meet the conditions that 1.7〈△ET〈＋1.1, the more help to improve the utilization of hot air. It provides a good theoretical basis for impinging jet ventilation in wide range of applications.
