PROBLEM TO BE SOLVED: To provide an air conditioner which enables accurate detection of abnormality in a connected capacity without any specific setting, even when it is installed at a place different in a commercial power frequency. SOLUTION: This air conditioner comprises an operating means 12 which is provided in a centralized control device 11 for setting the kind of commercial power frequency, a connectable capacity determining means 43 which detects the commercial power frequency discriminated by the operating means, through a bus communication circuit 1, and determines the capacity of an indoor unit connectable to each outdoor unit, according to the commercial power frequency, a capacity detecting means 42 which detects the capacity of the indoor unit connected to each outdoor unit by the communication of the bus communication circuit 1 and an abnormality determining means 44 which compares this detected capacity with the aforesaid connectable capacity and determines the presence or absence of the abnormality in a connected capacity. By this constitution, the presence or absence of the abnormality in the connected capacity can be detected accurately regarding all of refrigerating cycle units in a plurality, even when they are installed at places different in the commercial power frequency. |
