To the remote terminal device 22 via the line-side communication processing unit 32. The automatic abnormality canceling unit 6 transmits an abnormality canceling command to the outdoor unit 12 via the air conditioning-side communication processing unit 34 at the same time when the abnormality is detected. Further, when the abnormality code specifying the abnormality that has occurred is stored in the emergency operation possible abnormality storage unit 4, the operation control unit 7 determines that the emergency operation is possible, and issues an operation command to the outdoor unit 12. Is transmitted via the air-conditioning side communication processing unit 34. Since the air conditioner has been set in a state where no abnormality has occurred by receiving the abnormality release command in advance, the operation can be restarted by receiving the operation command.
[0024]
Here, when the operation monitoring unit 40 detects an abnormality again within a predetermined time after restarting the operation of the air conditioner, the automatic abnormality release unit 6 issues an abnormality release command to the operation control unit 7 in the same manner as described above. Transmits an operation command. However, the operation control unit 7 restarts the operation by the emergency operation in which the air conditioning capacity of the air conditioner is reduced by transmitting a frequency control command for fixing the operation frequency to m% (m <100).
[0025]
The operation monitoring unit 40 records, in the information storage unit 38, the detected abnormality occurrence, the restart of the operation, and the restart of the operation due to the emergency operation as operation history information. In addition, the contents of the operation control such as the restart of the operation and the emergency operation by the operation control unit 7 are notified to the remote terminal device 22 in the same manner as the abnormality detection. In the remote terminal device 22, the contents of the abnormality detection and the operation control are displayed on a monitor (not shown), and the maintenance worker goes to the site for repair when notified of the abnormality.
[0026]
Conventionally, emergency operation could not be performed unless maintenance personnel arrived at the site, but according to the present embodiment, operation is restarted or emergency operation is performed before maintenance personnel arrive. Therefore, the state in which the air conditioner is completely stopped due to the occurrence of abnormality can be shortened. Thereby, the discomfort given to the air conditioning user due to the complete stoppage of the air conditioner can be reduced.
