쾌적수면 알고리즘 개발을 위한 에어컨의 기류제어에 관한 연구

Abstract

Most people use air conditioner in daytime. But, they usually don’t use air conditioner at night. As global warning phenomenon is accelerated, the tropical nights phenomenon that outdoor temperature exceeds 25℃ happens frequently. In this way, as the tropical nights phenomenon happens frequently in summer, people who appeal inconvenience in sleep are increasing. So, it is helpful to sleep well using of air conditioner during the period that happens the tropical nights phenomenon in summer. Existent researches about sleep had been focused on diagnostic and treatment of disease in connection with sleep obstacle. In foreign case, some researches are achieved about relations between temperature and sleep. For example, effect of indoor temperature on change of sleep stage and body temperature, relations between regulation of body temperature and sleep, etc. Contents of these researches are insufficient to offer optimal control method of air conditioner for comfort sleep in summer. Therefore we need some control methods of air conditioner to keep human's thermal comfort. Existent researches about Indoor thermal comfort during sleep had been studied the fact that sleep comfort is influence of ambient temperature. But they did not apply to airflow. So the objective of this study is to define sleep comfort by ambient temperature fluctuations and airflow during middle part of sleep. This study was performed to evaluate sleep comfort based on the analysis of physiological signals, mean skin temperature and temperatureㆍhumidity in bedclothes. As results, we found that airflow stimulation assisted comfortable sleep.
