Air conditioning apparatus

An air conditioning apparatus comprising:

• an outdoor device that is connected to an AC power supply;
• and
• a plurality of indoor devices that are connected to the AC power supply through the outdoor device, wherein
• the outdoor device includes:
• a first current path through which AC power is supplied from the AC power supply to a compressor driving circuit through a first noise reduction unit that includes an inductive reactance, a first AC power-supply relay, and a first inrush-current suppression resistor;
• a second current path through which AC power is supplied from the AC power supply to the compressor driving circuit through the first noise reduction unit,
• a second AC power-supply relay, and a second noise reduction unit that includes a capacitive reactance;
• a third current path through which AC power is supplied from the AC power supply to a control-power-supply generation circuit through one of the indoor devices, a first outdoor power-feed switching relay, and a second inrush-current suppression resistor;
• and
• a fourth current path through which AC power is supplied from the AC power supply to the control-power-supply generation circuit through the first reduction unit, a second outdoor power-feed switching relay, and a surge-current suppression resistor having a lower impedance than the second inrush-current suppression resistor, by controlling on-off of the first AC power-supply relay and the second AC power-supply relay:
• the outdoor device supplies AC power of the AC power supply to the compressor driving circuit through the first current path or the second current path, and
• by controlling on-off of the first outdoor power-feed switching relay and the second outdoor power-feed switching relay:
• the outdoor device supplies AC power of the AC power supply to the control-power-supply generation circuit through the third current path or the fourth current path.
