Evaluation Methods of Indoor Odor and Air Quality in High Density Residential Areas

本研究的目的是建立高密度居住区室内气味和空气质量的评价方法。一开始我们设计和建造了一个新的空气质量测试室，可以控制新风供应、再循环空气、空气温度和湿度。对于感官室内空气质量的心理评价，我们开发了心理测量问卷，主要由气味强度、可接受性和不适性组成。研制了嗅觉刺激器和生理功能测量系统。生理功能测量项目为脑电、心率、心率变异性、面部皮温和肌电。体味心理测量学实验检验以前的气味指数和我们新的心理测量学问卷。Fanger(1988)提出的气味指数中的Off和Decolol单位并不总是适用于日本男性。使用我们的嗅觉刺激器和生理功能测量…此外，我们还进行了室内空气感官质量对人体生理机能影响的实验研究，为室内空气质量心理指标的制定提供生理学依据。4种同步生理测试结果表明，大多数气味物质对中枢神经系统和自主神经系统均有影响，部分气味物质对传入运动控制系统有影响。本实验应用于体臭的评价。结果表明，该传感器对体臭等多种气体成分的检测是有效的。利用气味传感器、二氧化碳和心理测量问卷的同步实验结果，探讨了神经网络在室内空气质量感官评价中的应用。探讨了神经网络在室内空气质量感官评价中的有效性。较少

The purpose of this study is to establish evaluation methods of indoor odor and air quality in high density residential areas. At the beginning we designed and built a new air quality test chamber, with which we can control fresh air supply, recirculation air, air temperature and humidity.For psychological evaluation of sensory indoor air quality, we developed a psychometrical questionnaire, largely composed of odor intensity, acceptability and unpleasantness. An olfactory stimulator and a physiological function measurement system were developed. The measuring items of physiological function were EEG, heart rate, heart rate variability, facial skin temperature and EMG.Psychometrical experiments for body odor were performed to examine the previous odor index and our new psychometrical questionnaire. The olf and decipol unit, one of odor index proposed by Fanger (1988), could not always adopt to Japanese male subjects. Using our olfactory stimulator and physiological function measurement … More system we carried out the experiments to examine the effect of sensory indoor air quality on human physiological function and to afford physiological basis to psychological indoor air quality index in our air quality test chamber. The results from the four simultaneous physiological measurements showed that both central and autonomic nervous system were affected by most of the odorants and that some kinds of odorant had an effect on afferent motor control system.A fragrance sensor coated with synthetic lipid membrane, simulated the membrane of olfactory cell, was adopted to evaluate indoor air quality. The experiments were performed to apply to the evaluation of body odor. The results showed that the sensor was effective to evaluate the multicomponent gase such as body odor. An application of neural network to evaluation of sensory indoor air quality was examined using the simultaneous experimental results of fragrance sensor, carbon dioxide and psychometrical questionnaire. We discussed the effectiveness of neural network to evaluate sensory indoor air quality. Less
