摘要
本文对兰州市41间集中供热的办公房间的冬季室内空气干球温度、相对湿度、风速等热环境参数进行了现场测试,同时以问卷方式对ASHRAE的7级热舒适指标进行了调查。结果表明,81%的办公人员对室内19.5℃的平均温度表示接受。而后通过编程计算热舒适指标PMV-PPD,得出兰州冬季供暖条件下80%的人感到舒适的温度范围为17—24℃,最佳室内空气参数为干球温度21℃,相对湿度20%。
In this paper, the filed measurement of indoor thermal environment parameters ,such as air temperature, relative humidity and air velocity, was carried out in 41 offices with central heating system in Lanzhou in winter. At the same time, thermal comfort indexes with seven orders that established by ASHRAE were investigated with questionnaires. The results demonstrated that 81% people felt comfortable at an average temperature of 19.5 ℃. Furthermore, based on the calculation of PMV-PPD indexes, it was concluded that 80% people felt comfortable at a temperature range from 17 ℃ to 24 ℃,and the optimal indoor parameters were of 21 ℃ and 20% RH.
