Synthetic Evaluation Index of Indoor Environment - and Optimal Control Method on it

对室内环境质量的定义和节能方面的介绍是室内环境优化控制的必要条件。本项目主要围绕以下三个主题进行规划：提出一种评价室内环境的综合指标。寻找防止混合能量损失的最有效的空调方法；建立预测室内空气温度和速度分布的模型。在资助的三年中，获得了以下结果：在从冷区到舒适区的升温过程等过渡条件下，色热假说得到了证实。在过渡状态下的生理反应中，平均皮肤温度和心率的后效分别体现在热身和降温过程中。提出了一种在二维平面上兼顾环境条件、生理条件和过渡条件下感觉的新模型。通过比例模型和幻灯片投影实验，环境墙体颜色的色热印象也随环境热条件的变化而变化。识别出一些敏感颜色和SD尺度。在空调实验室内对混合能量损失进行了研究。从数量上表明，冷却的内部和加热的外围区域之间的设定温度差异对混合能损失有很大影响。通过对某模型建筑的仿真，验证了混合能量损失对节能的重要性。提出了一种能够模拟室内空气温度垂直分布的混合模型，并用各种指标对空气分布系统进行了评价。采用各种数值方法对室内空气的温度和速度分布进行了数值计算，取得了较好的结果。

It is necessary for optimal control of indoor environment to define the quality of indoor environment and to introduce the aspect of energy saving.Present project was planned on the following three themes;1. To produce a synthetic index to evaluate indoor environment for occupants.2. To find the most efficient air-conditioning method to prevent from mixing energy loss, and3. To establish a model to predict temperature and velocity distributions of room air.The following results were obtained during subsidized three years.1. The hue-heat hypothesis was confirmed in transitional conditions such as warming up process from cold to comfortable zone.2. On physiological responses in transitional conditions, aftereffects of mean skin temperature and heart rate revealed themselves in warming up process and cooling down process, respectively.3. A new model that accounted for ambient, physiological conditions, and sensation in transitional conditions on two-dimensional plane was proposed.4. Hue-heat impression of ambient wall color also varied with ambient thermal condition through the experiments using scaled model and slide projection. Some sensitive colors and SD scales were recognized.5. Mixing energy loss was examined in Air-conditioning Experimental Chamber. It was quantitatively clarified that the difference of setting temperatures between a cooled interior and a heated perimeter zone greatly affected the mixing energy loss.6. The importance of mixing energy loss on energy saving was verified as a result of simulation of a model building.7. A mixing model that enabled to simulate vertical distribution of room air temperature was proposed and air distribution systems were evaluated using various indices.8. Numerical calculations of temperature and velocity distributions of room air were carried out by means of various kinds of numerical methods with fairly good results.
