中文摘要:
      本研究在有无风扇的情况下进行实验,通过改变暴露温度与暴露时长,研究了不同暴露经历对建筑内人员空调控制行为的影响。结果表明,经历28 ℃和30 ℃的热暴露后,受试者无风扇使用时最终选择的室内温度分别为25.3~26.3 ℃与25.7~26.7 ℃,而使用风扇后最终选择的室内温度分别为26.7~27.4 ℃与26.9~27.3 ℃,相比无风扇时上升了0.5~1.7 ℃与0.6~1.3 ℃。受试者的变温需求(初始与最终)在无风扇使用时与暴露时间呈二次非线性关系,在有风扇使用时呈线性关系。各工况中,人员变温需求与室内温度呈三次非线性关系,与人员的总体热感觉存在线性相关性。暴露温度、暴露时间和有无风扇三个因素对控制行为的单独作用显著( p < 0.05 ),其中暴露温度的影响最大,暴露时间的影响最小。
英文摘要:
      A series of experiments with and without fans were conducted in a real office room in Changsha, China to investigate the effect of different exposure temperatures and time periods on subjects’ control behaviors over indoor air-conditioning systems. The results show that when the exposure temperatures were 28 ℃ and 30 ℃, the final indoor temperature chose without fans were 25.3~26.3 ℃ and 25.7~26.7 ℃, respectively, while the final indoor temperature with fans were 26.7~27.4 ℃ and 26.9~27.3 ℃, respectively, with the increase of 0.5~1.7 ℃ and 0.6~1.3 ℃. The initial and the final requirements for changing indoor temperatures had second-order correlations with exposure time periods without fans use and had linear correlations with exposure time periods with fans. Besides, requirements for changing indoor temperatures had three-time non-linear correlations with indoor temperatures and had linear correlations with thermal sensation votes. The effects of exposure temperatures, exposure time periods and fan-uses on control behaviors were significant, and exposure temperatures had the maximum effect while the exposure time periods had the minimal effect.
