<P>PROBLEM TO BE SOLVED: To solve such a problem that a compressor is susceptible to breakage since the compressor is operated in a region in which the compressor cannot be protected by a conventional current limit value, when the compressor of conventional voltage specifications is used in an area adopting high-voltage specifications, in the air conditioning device including an inverter device. <P>SOLUTION: A control device 4 determines whether the air conditioning device is used in a conventional power-supply voltage area, or is used in a high power-supply voltage area, based on a voltage value detected by a direct-current bus bar voltage detection device 10. In the use in the high power-supply voltage area, a current limit value responding to a value of the direct-current bus bar voltage detection device 10 is delivered, and the compressor is protected by the delivered current limit value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
