焦作夏季居住建筑人体热舒适现场研究

Field study on occupant thermal comfort in residential buildings of Jiaozuo city in summer

采用环境参数测量与问卷调查同步进行的方式,研究了混合供冷模式下人们的热舒适性。结果显示,该地区夏季实测热中性温度为27.7℃,预测热中性温度为25.4℃,由热感觉法和直接询问法得到的80%可接受温度范围的上限分别为28.8℃和29.2℃,由这两种方法得到的期望温度分别为27.4℃和24.0℃;在混合供冷模式下,由于存在由空调环境进入非空调环境的情况,所以对热环境的不满意率要高于自然通风状态,可接受温度上限比自然通风状态低。

Studies the thermal comfort of occupants in mixed cooling mode in a synchronous way of the field measurement and questionnaire survey.The results show that the measured thermal neutral temperature and predicted thermal neutral temperature is 27.7 ℃ and 25.2 ℃ respectively in this area in summer;the upper limit of the operative temperature corresponding to the accepted thermal environment by 80% of the occupants is 28.8 ℃ and 29.2 ℃ respectively,and the preferred temperature is 27.4 ℃ and 24.0 ℃ respectively,obtained from the thermal sensation method and direct inquiry method;Because of the condition of entering a non-air conditioned space from an air-conditioned space existing in the mixed cooling mode,the dissatisfied percent with the thermal environment is higher than that in natural ventilation mode,and the upper limit of the acceptable temperature is lower than that in natural ventilation mode.
