| Outline of Final Research Achievements |
In this study, the measurement of the skin temperature and the subjective evaluation were conducted under a ceiling fan in the climate chamber in the summer. Convective heat transfer coefficient was measured by a thermal mannequin experiment and the thermal sensation was predicted. The temperature and velocity distribution and the electricity consumption were measured and the subjectivity evaluation of the occupants was conducted by the questionnaires in an actual office. Then, CFD simulations in nonisothermal and isothermal condition were performed. The influence of the room volume and the rotational speed of the ceiling fan on the indoor airflow and temperature distribution was investigated in the isothermal condition. The influence of the arrangement of the air conditioner and the ceiling fans was investigated in the cooling and heating condition. Finally, a selection chart of a ceiling fan was gained from the reduction effect of the electricity consumption and SET*.
