| Outline of Final Research Achievements |
The objective of this research is to establish an energy saving method to control the ventilation rate dynamically based on the olfactory adaptation and to develop the calculation method of odor intensity variation under changing odor concentration. Using the sensation data obtained from olfactory test on odor intensity, two simple assumptions were introduced. The first assumption is that instantaneous odor intensity is determined by Weber-Fechner law even in transient process of olfactory adaptation, and the second one is that the increase of threshold is calculated by impulse response linearly. Based on these assumptions, olfactory adaptation model was developed. By means of this model, varying ventilation rate can be calculated. As a research results, it is made possible to control the ventilation rate at the minimum amount to prevent the occupants from feeling the odor inside the room.
