不同温度下立式塔扇吹风时人体热反应变化

The Changes of Human Thermal Reaction when the Vertical Tower Fan is Blown at Different Temperatures

为了探究在立式塔扇吹风影响下人体热反应的变化情况,本文在实验室对受试者进行了主观问卷调查及实际测试,分析了风速和温度变化时人体热感觉及吹风感的变化情况,将温度和风速的变化放到一起考虑并进行了定性的分析,给出了其具体的相关关系。研究表明,风速对热感觉会产生很大的影响,可以考虑通过风速的增加来实现热感觉的降低,但是风速过大时人体会产生较为强烈的吹风感,因此办公环境下风速必须限制在一定范围内,本文给出了吹风感小于1和2时的风速限值。另一方面,在本实验的验证中,得出温度和风速对热感觉的联合影响程度占68.4%,对吹风感的联合影响程度占65.7%,这也说明,人体主观参数不仅受到温度和风速的影响,也会和许多其它因素关联。

To explore the changes of human thermal reaction when the vertical tower fan is blown at different temperatures,subjective questionnaire survey and field testing were conducted in the laboratory in this research,the changes of human thermal sensation and draft sensation were analyzed during wind speed and temperature change.The changes of temperature and wind speed were considered together and qualitative analysis was carried out.The correlation between the thermal reaction and environmental parameters is given.Studies have shown that wind speed has a great influence on the thermal sensation.It can be considered to reduce the thermal sensation by increasing the wind speed.However,when the wind speed is too high,the human body will have a strong draft sensation,so the wind speed must be limited within a scope in the office environment,this research gives the wind speed limit when DS is less than 1 and 2.On the other hand,in the verification of this experiment,the combined effect of temperature and wind speed account for 68.4%of the total change in thermal sensation,and the combined effect account for 65.7%of the total change in draft sensation,which indicates that people’s subjective parameters are not only affected by temperature and wind speed.The impact will also be associated with many other factors.
