北疆地区室内热环境实测及人体热反应研究

Measurement of indoor thermal environment and study on human thermal reaction in northern Xinjiang

为探究北疆地区自然通风状况下的室内热环境及人体热反应,选取一单人宿舍进行约6个月的实测,结果表明,室内温度波动较大,最高与最低温差近17℃,最高温度达35.4℃。以ASHRAE 55—2017为标准,对室内热环境进行评价,室内相对湿度始终满足标准要求,室内温度是唯一的影响因素,4、5、9及10月满足热舒适的要求,但要注意保暖,6、7和8月室内温度过高,即使完全打开门窗形成对流,对室内热环境的改变也是微弱的,需采取其他降温措施。线性回归结果显示,室内环境对人体皮肤温度的影响随室内环境温度的升高而减小。

In order to investigate the indoor thermal environment and human thermal response under natural ventilation conditions of northern Xinjiang,this paper selected a single dormitory for a 6⁃month experiment.The result showed that the indoor temperature fluctuated greatly,and the difference between the highest and the lowest temperature was nearly 17℃,while the highest was 35.4℃.Furthermore,based on ASHRAE 55—2017 to evaluate the indoor thermal environment,the indoor relative humidity always met the standard requirements,while the indoor temperature was the only factor.The temperature in April,May,September and October could meet the requirements of the thermal comfort,but keeping warm should be paid attention.Indoor temperatures in June,July and August were too high.Even if the windows and doors were completely opened to provide ventilation,the change of indoor thermal environment was small,and additional cooling measures need to be taken.The linear regression results showed that the influence of indoor environment on human skin temperature decreased with the increasing indoor environment temperature.
