研究了不同送风速度下碰撞射流通风房间内的热环境分布特征,并对室内的热舒适性进行了分析比较。结果表明,碰撞射流通风用于供暖时,送风能量能够被人员活动空间充分利用,并且增大送风速度能够缓解碰撞射流供暖房间内的温度分层现象。虽然碰撞射流通风近送风口附近的近地面处气流速度较大,但热舒适分析表明,在本文研究的送风参数范围内,热舒适参数均在可接受的范围之内。
The distribution characteristics of the thermal environment in the collisional jet ventilation room under different blast velocities were studied, and the indoor thermal comfort was analyzed and compared. The results show that when the collision jet ventilation is used for heating, the blast energy can be fully utilized by the personnel activity space, and increasing the air supply velocity can alleviate the temperature stratification in the collision jet heating room. Although the collisional jet ventilation is near the ground near the air inlet, the air velocity is relatively high, but the thermal comfort analysis shows that the thermal comfort parameters are within the acceptable range within the parameters of the air supply studied in this paper.
