Abstract

This system correctly obtains a thermal sensation of a person in a room to provide a comfortable environment. A first parameter deriver derives, as a first parameter, a ratio of a low frequency component to a high frequency component in a variation of R-R intervals of a person, based on his/her body movement. A second parameter deriver derives, as a second parameter, any one of a coefficient of variation of R-R intervals, a respiration rate, or a heart rate of the person, based on the body movement of the person. An estimator estimates a thermal sensation of the person, based on the first parameter and the second parameter. A CPU for air-conditioning control controls an air-conditioning capacity of the air conditioner, based on a result of the estimation by the estimator.
