Air conditioning system

Abstract

An air-conditioning system conditions air in a target space. The air-conditioning system includes a detector, an estimator, and a control unit. The detector detects a physiological quantity of a target person in the target space. The estimator estimates a biological rhythm of the target person based on the physiological quantity. The control unit controls a thermal environment of the target space in synchronization with the biological rhythm estimated by the estimator.
