| Research Abstract |
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.
