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.

1.空气温度变化的可视化。在装有风机盘管的房间内，从天花板到地板悬挂日本纸，并记录其温度图，作为从加热/冷却开始1小时的室内空气温度分布。2.人体热舒适性实验在一个冷热交替的房间内，对32名大学生进行了舒适感、热感、辐射感、气流感和湿感的实验。同时还测量了空气温度、空气流速、探头温度、相对湿度。3.与实验条件相同的数值预测在与实验室相同的房间内，采用两方程湍流模型进行数值预测，并将计算结果与实验数据进行定性比较。虽然日本纸受到周围墙壁辐射相互作用的影响，但结果和实验显示出合理的一致性。
