Abstract:
1. An air conditioner comprising: a heat exchanger which exchanges heat with air by passing a coolant therethrough; an anti-freeze apparatus which prevents the freeze of water on the surface of the heat exchanger supplying energy to the heat exchanger; and a control until which controls the anti-freeze apparatus according to operating conditions of the air conditioner, wherein the anti-freeze apparatus comprises: an electrode unit which includes a plurality of electrodes that generate an electric field in the heat exchanger; and a voltage generation unit which applies a voltage to the electrodes, the air conditioner further comprises a current detection unit which detects a current that flows into the electrode unit, wherein the control until controls the voltage generation unit according to the result of the detection performed by the current detection unit, wherein the control unit does not apply a voltage to the voltage generation unit if the result of the detection performed by the current detection unit is 0.
