地面对人体的角系数计算的准确性,对于评价地辐射采暖房间热舒适十分重要。文章分析了地面尺寸和面积、人体位置对角系数的影响及角系数变化特征。同时,文章也给出了当地面存在遮挡时,地面对人体角系数的计算方法和公式。最后通过实例证明,是否考虑地面遮挡对角系数计算的准确性存在显著影响。
The accuracy of the calculation of the angle coefficient of the ground on the human body is very important for assessing the thermal comfort of radiant heating rooms. The article analyzes the influence of the size and area of the ground, the diagonal coefficient of the human body position, and the variation characteristics of the angle coefficient. At the same time, the article also gives the calculation method and formula of human body angle coefficient when there is occlusion on the ground. Finally, an example is given to prove whether there is a significant impact on the accuracy of the calculation of the diagonal coefficient of ground obstructions.
