AIR-CONDITIONING CONTROL APPARATUS AND METHOD

摘要

[Problem];Accurately to detect the presence or absence of a person even when a background temperature rises near the surface temperature of a person.;[Solving Means];Equipped with a background-temperature calculation unit that calculates a background temperature that relates to a background temperature that is a background temperature of a person from thermal images, an air-conditioning control unit compares a judgment temperature Tj for judging whether it is necessary to start forced cooling in the room RM and a background temperature Tb obtained by the background-temperature calculation unit, and starts forced cooling to lower the background temperature Tb at the point when the background temperature Tb is above the judgment temperature Tj (Tb>Tj).

主权项

1. An air-conditioning control apparatus comprising:
a person-detection unit that detects the presence or absence of a person in a room based on a thermal image of the room generated from data outputted from temperature sensors arranged in the room RM that is targeted for control; an air-conditioning control unit that implements air-conditioning control of the room based on person-detection results obtained by the person-detection unit; and a background-temperature calculation unit that calculates the background temperature that relates to the background region in the background of a person from the thermal images, wherein the air-conditioning control unit compares the judgment temperature for judging whether it is necessary to start forced cooling in the room and the background temperature, and starts forced cooling to lower the background temperature at the point when the background temperature is above the judgment temperature.
