| Research Abstract |
1. Visualization of air temperature transition.
In a room with fan coil unit, Japanese paper was hung down from ceiling to floor and its thermographs were recorded as indoor air temperature distribution for 1 hour from starting of heating/cooling. 9 case studies were performed on outlet air volume high, middle and low and outlet air angle 60,50 and 45 degree.
2.Experiments with subjects on thermal comfort.
The experiments in a room with heating/cooling were performed with 32 college age subjects on comfort sensation, thermal sensation, radiation sensation, air flow sensation and wetness sensation. And air temperatures, air velocities, grobe temperature, relative humidity are also measured simultaneously. Then each sensation votes, environmental data and thermal comfort index were compared each other.
3.Numerical prediction in the same condition with experiment.
In a room same as experimental room, numerical prediction was conducted with two equation turbulence model and calculation results were compared with experimental data qualitatively. Though Japanese paper was affected by radiation interaction from surrounding walls, results and experiments shown a reasonable agreement.
