| 在有无风扇的情况下，通过改变暴露温度与暴露时长，研究了较高空气温度的偏热环境下不同热暴露经历对中国长沙某办公房间内人员分体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长呈二次非线性关系，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、暴露时长和有无风扇3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，暴露时长的影响最小． |

| 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 at higher air temperatures on subjects′ control behaviors over split-type air-conditioners. The results show that when the exposure temperatures are 28 ℃ and 30 ℃, the final indoor temperatures chosen without fans are 25.3-26.3 ℃ and 25.7-26.7 ℃, respectively, while the final indoor temperatures with fans are 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 have quadratic nonlinear correlations with exposure time periods without fans and linear correlations with exposure time periods with fans. Besides, requirements for changing indoor temperatures have cubic nonlinear correlations with indoor temperatures and linear correlations with thermal sensation votes. The effects of exposure temperatures, exposure time periods and fan-uses on control behaviors are significant(p<0.05), and exposure temperatures have the maximal effect while the exposure time periods have the minimal effect. |
