PROBLEM TO BE SOLVED: To reliably supply a generated output of a frequency matching a frequency of a commercial system.SOLUTION: In the air conditioning system, in which an outdoor unit 2 includes a gas engine 10 for driving compressors 12a, 12b, a generator 11 driven by the gas engine 10, and a system interconnection inverter 33 for outputting a generated output of the generator 11 to a commercial system 36, and which can perform a normal operation of supplying power to loads including indoor units 3a, 3b via system interconnection of the generated output of the generator 11 to the commercial system 36, and a self-sustaining operation of supplying the generated output of the generator 11 in a state of disconnection from the commercial system 36 to the loads including the indoor units 3a, 3b, the outdoor unit 2 is provided with a nonvolatile storage section 39c for storing a frequency of power of the commercial system 36 detected during the normal operation, and in the self-sustaining operation, the generated output of the generator 11 is converted to power of the frequency stored in the storage section 39c by the system interconnection inverter 33 before being output to the loads. |
