Patent ID: 8323081

Claim:
An air-conditioning system, comprising: an air conditioner, a terminal to be measured provided with a wireless communication function, and at least three wireless base stations that transmit and receive a distance-measuring signal to and from the terminal to be measured by wireless communication, wherein each of the wireless base stations measures a distance to the terminal to be measured and transmits measured distance data to the air-conditioner, the air-conditioner includes an operation part that controls the air-conditioner and that calculates the position of the terminal to be measured on the basis of the measured distance data and positional information of each of the wireless base stations, and calculates a position of the terminal to be measured to adjust a wind direction to the calculated position of the terminal to be measured with the operation part, the air-conditioner integrally includes a sensor that measures a predetermined physical quantity and that is capable of controlling a measuring direction to a desired direction, the sensor notifies a measurement result of the sensor at the position of the terminal to be measured to the operation part, the air-conditioner adjusts the physical quantity at the position of the terminal to be measured based on the measurement result of the sensor, and each of the at least three wireless base stations is disposed at each corner of an isosceles triangle having only two equal sides that is formed within the air-conditioned space by the air-conditioner while height from a base of the isosceles triangle to an apex thereof and length of a base of the isosceles triangle are equal to a maximum communication distance of the wireless base stations.
