流动的空气可以在较热的环境中大大改善人体的热感觉 ,但同时也会引起不愉快的吹风感。该文通过考察在气流脉动强度为 2 5 %和 40 % ,相对湿度为 35 %和 6 5 % ,空气温度在 2 6～ 30 .5℃范围内变化的等温环境中人体对风速的选择 ,研究了紊动气流对人体热感觉的影响。受试者在气候室中选择令他们满意的风速 ,并回答有关热舒适和吹风感的问卷。通过对实验数据的总结分析 ,发现高气流脉动强度可以改善中性 -热状态下人体的热感觉并减少吹风感的产生 ;将吹风感的概念加以推广 ,提出了一个预测等温较热环境中产生吹风感机率的数学模型。
The flowing air can greatly improve the body’s thermal feeling in a hot environment, but it can also cause an unpleasant feeling of blowing air. In this paper, by investigating the human body’s choice of wind speed in an isothermal environment with fluctuating air flow of 25% and 40%, relative humidity of 35% and 65% and air temperature varying from 26 ° C to 30.5 ° C, The impact of turbulent airflow on the body’s thermal sensation. Subjects in the climate room selected the wind speed that satisfied them, and answered the questionnaire about thermal comfort and hair feeling. Through the analysis of the experimental data, it is found that the high airflow pulsation strength can improve the body’s thermal sensation and reduce the feeling of hair blowing in the neutral-thermal state. The concept of the sense of hair blowing is generalized and a new method, Mathematical model of the probability of hair blowing.
