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

1.空气温度变化的可视化：在一个有风机盘管的房间里，日本纸从天花板挂到地板上，从供暖/降温开始，记录下1小时的室内空气温度分布。2.受试者进行热舒适性实验。32名大学生在有冷暖条件的房间中进行舒适感、热感、辐射感、气流感觉和湿感的实验。同时还测量了气温、风速、格罗布温度、相对湿度。3.在与实验相同的条件下进行数值预测，在与实验相同的房间内，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。尽管日本纸受到来自周围墙壁的辐射相互作用的影响，但结果和实验表明，这一点是合理的。

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.
