夏热冬冷地区图书馆阅览室热舒适调查分析--以江西南昌为例

Investigation and Analysis of Thermal Comfort in Hot Summer and Cold Winter Areas--Take a University in Nanchang City,Jiangxi Province as a example

为了研究夏热冬冷地区冬季室内热舒适状态并节约能耗,以南昌一所高校的阅览室为研究对象,连续3 d测得室内温湿度和风速,计算房间的预测平均评价PMV指标值,得到室内预测中性温度为18.9℃。用ASHRAE七级热感觉指标对房间的热舒适性进行问卷调查,得到205份有效问卷,计算热感觉投票TSV、热舒适投票TCV,拟合TSV直线可得到阅览室实测中性温度为17.5℃,低于期望温度,表明室内同学适应偏冷环境。通过中性温度为房间空调温度设置提供了参考,计算了可节省的能耗;并测得阅览室内二氧化碳浓度过高使得舒适度降低,应适当通风。

In order to study the indoor thermal comfort state in hot summer and cold winter areas and save energy consumption,the reading room of a university in Nanchang was used as the research object.The indoor temperature,humidity and wind speed were measured for three consecutive days.The PMV index value of the room was calculated to obtain the predicted neutral temperature,which is 18.9°C.Using ASHRAE seven-level thermal sensation index to conduct a questionnaire survey on the thermal comfort of the room,get 205 answers.Calculating the TSV,TCV,and fit the TSV straight line to get the neutral temperature of the reading room is 17.25℃,which is lower than the expected temperature,indicating that students are adapting to the colder environment.The neutral temperature provides a reference for the room air conditioning temperature setting,and tries to calculate the saved energy.It is measured that the concentration of carbon dioxide in the reading room is too high and the comfort level is low,so proper ventilation should be provided in this room.
