WIPO Patent Application WO/2019/220874

A1

This air-conditioning control device controls an air-conditioning indoor unit according to a terminal position of a terminal held by a user, and comprises: an ultrasonic detection processing unit that detects an ultrasonic wave issued from the terminal via a first ultrasonic sensor disposed on the air-conditioning indoor unit and a second ultrasonic sensor disposed at a position different from the position of the air-conditioning indoor unit; an arrival time difference calculation unit that calculates an arrival time difference, which is the difference between the time at which the ultrasonic wave was detected by the first ultrasonic sensor and the time at which the ultrasonic wave was detected by the second ultrasonic sensor; a position estimation unit that estimates the terminal position of the terminal on the basis of the arrival time difference; and an indoor-unit control unit that controls the air-conditioning indoor unit on the basis of the terminal position.
