本文阐明了下部送风房间热力分层和垂直温度分布规律,给出了确定垂直温度分布曲线的方法及确定最佳运风量的原理。为了计算冷负荷,作者初步推荐了不同位置热源的负荷系数,并且说明了如何决定送风口的型式与数量和相关数据。最后在实验基础上分析了地板空调的热感觉,其结果说明这种逆风系统在适宜的风量与温度下能够提供舒适条件,并使风感百分数低于15%。
This paper clarifies the thermal stratification and vertical temperature distribution of the lower air supply room, and gives the method of determining the vertical temperature distribution curve and the principle of determining the optimal air flow rate. In order to calculate the cold load, the author initially recommended the load factor of the heat source in different locations and explained how to determine the type and quantity of the air outlet and related data. Finally, on the basis of experiments, the thermal sensation of the floor air conditioner was analyzed. The results show that this upwind system can provide comfortable conditions under suitable air volume and temperature, and the percentage of wind sensitivity is less than 15%.
