Abstract
When an outdoor machine includes a signal line connector for receiving ON/OFF signals for a compressor, an outdoor machine drive control unit of an air conditioner includes an inverter device for supplying power variable in frequency to the compressor and a control device for controlling the inverter device to gradually increase the number of revolutions of the compressor when the ON/OFF signal for the compressor received through the signal line connector changes from the OFF condition to the ON condition. The air conditioner outdoor machine drive control unit 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.
