A Study on Visualization and Measurement by Thermography of Indoor Air Temperature Distribution in a Room with Heating/Cooling

1. 空气温度转变的可视化。在一个装有风机盘管的房间里，将日本纸从天花板吊到地板，记录其热像图为从供暖/制冷开始1小时内的室内空气温度分布。对出口风量高、中、低、出口风角60、50、45度进行了9例案例研究。热舒适实验。对32名大学生进行了舒适感觉、热感觉、辐射感觉、气流感觉和湿润感觉的实验。同时测量空气温度、空气速度、温度、相对湿度。然后对各感觉投票、环境数据和热舒适指数进行比较。与实验相同条件下的数值预测。在与实验室相同的室内，采用双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。

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.
