고령자용 감성에어컨 개발을 위한 온열쾌적감 평가

Abstract

In this study, To prepare for the upcoming aging society, considering the sensitivity of the elderly a sense of thermal comfort was evaluated. TSV, CSV, MST, ECG and EEG of the elderly by taking advantage of a sense of thermal comfort were evaluated. The experiment was conducted twice. In summer 2008, the four elderly women subjects and four young women were conducted a first experiment. 2nd experiment, summer 2010 Youth Men's 59 test subjects were carried out. The experimental conditions were those room temperature 26℃ at 28℃, relative humidity of 40% and 55%, 70%. And Clothing Insulation 0.35clo, and Typical metabolic heat generation for various actions was assumed to be 1.1. The results are as follows. TSV in the elderly than the young man is sensitive to temperature changes. If you change the time of the youth as the young man changes, but there is little change in elders. 28℃ to young men feel more comfortable. And 26℃ to young women feel more comfortable. 28℃, while the elderly women feel more comfortable. When, the relative humidity changes, young men have a higher correlation coefficient in 26℃ environment. Young women and elderly women CSV and TSV, but increased the loss. In particular, young women as young men and a higher correlation coefficient in 26℃ environment. In contrast, older women in the 28℃ environment, the correlation coefficient was higher. Young men MST were leaving the comfortable area in any environment. However, Young women were at 26℃ 70%, elders were at 26℃ environment, Left the comfort area. When, the relative humidity changes, young’s have a higher correlation coefficient than elderly women. And Elders skin temperature in legs and arms were higher than young’s subjects. Statistical analysis results, MST of the other three subjects decreased significantly, while maintaining a relationship with each other, but the average difference. Analysis results of ECG and EEG, young’s have a lower stress than elderly women in 26℃ environment. Taken together all results TSV and CSV, MST, ECG, EEG appears differently depending on the gender and age. And Subjective questionnaires and physiological signals showed that the correlation between. Therefore, the body of the elderly in this study, physiological and emotional considering will be able to create a comfortable thermal environment. In addition, to maintain the health of the elderly through the development of the air conditioning in preparation for upcoming aging society are expected to be able to contribute.
