遵义地区高校建筑冬季室内自然通风情况下室内热环境和热舒适调查研究

On Winter Indoor Thermal Environment and Thermal Comfort in Naturally Ventilated University Buildings in Zunyi

本研究对遵义某高校在冬季采用自然通风的教室和学生寝室的室内热环境及热舒适状况进行了现场调查,发现在室内缺乏集中供暖、空调等采暖设备的情况下,冬季室内温度变化范围为11.57℃-19.80℃,不在ASHRAE(American Society of Heating Refrigerating and Airconditioning Engineer,美国采暖、制冷与空调工程师学会)规定的冬季室内热舒适温度区间(20℃-23℃)内。通过分析预测平均投票(Predicted Mean Vote,PMV)与实际热感觉投票(Actual Mean Vote,AMV)的差异,得到了在实测模式下热环境的可接受率为72.53%,热中性温度为20.27℃,可接受温度区间为16.60℃-23.95℃的结论。为改善该校建筑室内热环境质量以及进行被动式节能改造提供了依据。

In this study,the indoor thermal environment and thermal comfort of naturally ventilated classrooms and students'dormitories in a university in Zunyi in winter were investigated.It was found that there was a lack of central heating,air conditioning and other heating equipment in the room.The range of indoor temperature in winter is 11.57℃-19.80℃,which is not within the indoor thermal comfort temperature range(20C-23℃)specified by the American Society of heating,Refrigeration and Air conditioning Engineers(ASHRAE(American Society of Heating Refrigerating and Airconditioning Engineer,).By analyzing and predicting the difference between the average voting(Predicted Mean Vote,PMV)and the actual thermal sensation voting(Actual Mean Vote,AMV),the acceptability of the thermal environment is 72.53%and the thermal neutral temperature is 20.27C under the measured mode.The acceptable temperature range is 16.60℃-23.95℃.It provides a basis for improving the indoor thermal environment quality of the school building and carrying out passive energy-saving transformation.
