Design of Air-conditioning System using Ceiling Fan in Consideration of Children' s Health and Comfortable in Classroom

本研究在安装吊扇的教室里进行了调查和专题实验，检测了吊扇对室内空气速度和温度分布的影响。然后，在气候室中，像吊扇一样长时间暴露在向下气流的情况下，测量主观评价和皮肤温度的时间变化。获得了热感觉和热舒适性的评价结果。此外，还对吊扇的单元个数和位置进行了CFD分析。研究了吊扇对室内气流组织和温度分布的影响，为吊扇空调系统的设计提供了依据。

In this study, survey and a subject experiment were conducted in the classroom in which the ceiling fan was installed, and examination for effect of a ceiling fan on indoor air velocity and temperature distribution was performed. Then, in the climate chamber, the measurement for the time variation of the subjectivity evaluation and skin temperature was performed at the long time exposure of downward airflow like a ceiling fan. The evaluation of thermal sensation and thermal comfort was acquired. Furthermore, CFD analysis as a parameter of the unit number and the position of the ceiling fan was conducted. The influence of the ceiling fan on indoor airflow and temperature distribution was investigated, and gained the data contributed to a design of air-conditioning system using ceiling fans.
