项目摘要

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.

室内环境的最佳控制需要定义室内环境的质量和引入节能方面。本项目计划在以下三个主题：1。提出一个综合性的评价指标，用于对居住者的室内环境进行评价.寻找最有效的空调方式，防止混合能量损失;建立室内空气温度和速度分布的预测模型，在补贴的三年中取得了以下结果.在从寒冷区到舒适区的升温过程等过渡条件下，证实了色调热假说.在过渡条件下的生理反应中，平均皮温和心率的后效分别表现在升温过程和降温过程中.提出了一种新的模型，该模型在二维平面上考虑了环境、生理条件和过渡条件下的感觉.通过缩尺模型和幻灯片投影实验，发现环境墙体颜色的色调热印象也随环境热条件的变化而变化。识别出一些敏感的颜色和SD刻度.在空调实验室中对混合能量损失进行了实验研究。定量地阐明了冷却的内部和加热的周边区域之间的设定温度的差异极大地影响混合能量损失。通过建模仿真，验证了混合能量损失对节能的重要性.提出了一个能够模拟室内空气温度垂直分布的混合模型，并使用各种指标对空气分配系统进行了评估.采用多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，得到了较好的结果。
