微型建筑空间尺寸对人体热舒适的影响研究

Study on Effects of Micro Building Space Size on Human Thermal Comfort

搭建可变空间尺寸1∶1实体建筑模型,在改变建筑空间尺寸和室内热源功率的条件下,对室内热环境参数进行测试,并结合对人体热舒适指标的问卷调查,对人体热舒适进行研究。研究结果表明,在不同热源功率下,随着建筑空间尺寸的减小,室内空气和围护结构的平均温度均有所上升,热辐射对室内空气温度和人体热舒适的影响作用明显增强。冬季实验工况下,当空间尺寸在4.00 m^2之下时,热源功率在0~1500 W范围内,随着功率的增加,人体热舒适投票值会出现临界点。

The variable space size 1∶1 physical building model was built to test indoor thermal environment parameters under the condition of changing the building space size and indoor heat source power.Combining above parameters with the results of questionnaire survey on the thermal comfort index of human,this paper developed research about human thermal comfort.The results indicate that under the different heat source power,with the decrease of building space size,the average temperature of indoor air and building envelope increases,and the influence of thermal radiation on indoor air temperature and human thermal comfort increases obviously.Under the experimental conditions in winter,when the space size is below 4.00 m^2 and the heat source power ranges from 0 W to 1500 W,there will be a critical point of the voting value of the human thermal comfort as the power increasing.
