PROBLEM TO BE SOLVED: To make it possible to accurately estimate the service life of a battery and to notify a user of the expiration of the service life in an air conditioning system.SOLUTION: In an air conditioning system in which an outdoor unit 2 includes a gas engine 10 driving a compressor; and a generator 11 driven by the gas engine 10, and that can perform a self-sustained operation for supplying generated power in the generator 11 to loads including indoor units at a time of blackout, the outdoor unit 2 includes: a battery 49 used to start the gas engine 10 at a time of the self-sustained operation; and a temperature sensor 72 measuring a surrounding temperature of the battery 49. A casing 60 of the outdoor unit 2 includes a machine room 62a on a lower stage, and a heat exchange room 62b on an upper stage. The battery 49 and the temperature sensor 72 are arranged in the heat exchange room 62b. If a temperature-time integrated value based on the temperature detected by the temperature sensor 72 reaches a predetermined value, a user is notified of expiration of the service life of the battery 49. |
