Abstract
When an outdoor machine 2 includes a signal line connector 21 for receiving ON/OFF signals for a compressor, an outdoor machine drive control unit 30 of an air conditioner includes an inverter device 32 for supplying power variable in frequency to the compressor 22, and a control device 33 for controlling the inverter device 32 to gradually increase the number of revolutions of the compressor 22 when the ON/OFF signal for the compressor received through the signal line connector 21 changes from the OFF condition to the ON condition. The air conditioner outdoor machine drive control unit 30 enables to construct an inverter-type air conditioner by using a general heat-pump-type indoor machine and merely mounting it in an outdoor machine.
