Air conditioner
An air conditioner includes an indoor unit and a remote controller connected to the indoor unit through two lines to receive power from the indoor unit and perform communication with the indoor unit. The indoor unit includes a first modulation switching element to modulate power according to a communication signal that is transmitted to the remote controller, a first demodulation switching element that is driven according to a communication signal transmitted from the remote controller, and a first distribution resistor to demodulate the communication signal transmitted from the remote controller. The remote controller includes a second modulation switching element to modulate power according to a communication signal that is transmitted to the indoor unit, a second demodulation switching element that is driven according to modulated power transmitted from the indoor unit, and a second distribution resistor to demodulate modulated power transmitted from the indoor unit to obtain a communication signal.
