Abstract
An air conditioning apparatus, being a power efficient and highly resistant to external noise, includes: an outdoor device; and indoor devices. The outdoor device includes: a first current path, through which AC power is supplied; and a second current path, through which AC power is supplied from the AC power supply to the control-power-supply generation unit through a first noise reduction unit, a second outdoor power-feed switching relay, and a surge-current suppression resistor. When there is a possibility an inrush current to the control-power-supply generation unit to be generated, the outdoor device supplies AC power of the AC power supply to the control-power-supply generation unit through the first current path. When there is not a possibility for an inrush current to the control-power-supply generation unit to be generated, the outdoor device supplies AC power of the AC power supply to the control-power-supply generation unit through the second current path.
