False determination in the presence or absence of a person in a in a room is limited. An air conditioner suspends an air conditioning operation if a room is vacant. If at least one of motion detectors, each provided to one of the indoor units, starts to detect the presence of a person during suspension of the air conditioning operation, an indoor controller of an indoor unit sums, for each of the motion detectors, time periods in which the presence of the person is detected to obtain a detection time period sum. If any one of detection time period sums, each for one of the motion detectors, reaches a reference value within a predetermined time period, the outdoor controller causes the air conditioner to resume the air conditioning operation. |

1. An air conditioning system comprising:
an air conditioner including an outdoor unit and indoor units belonging to a common control system, the indoor units being installed in a common room; motion detectors each provided to one of the indoor units, and configured to detect presence of a person in the room; and a controller configured to cause the air conditioner to suspend an air conditioning operation if the room is vacant, wherein while the air conditioning operation is suspended, the controller; obtains a detection time period sum by summing, for each of the motion detectors, time periods in which the presence of the person is detected, if at least one of the motion detectors, each provided to one of the indoor units, starts to detect the presence of the person during the suspension of the air conditioning operation; and causes the air conditioner to resume the air conditioning operation if any one of detection time period sums, including the detection time period sum and each for one of the motion detectors, reaches a reference value within a predetermined time period after the at least one motion detector starts to detect the presence of the person. |
