Abstract: Provided are an air conditioner and a control method of an air conditioner capable of improving efficiency of an inverter compressor by injecting superheated steam into the inverter compressor during heating and cooling. An air conditioner includes: a dual inverter compressor including a first inverter compressor and a second inverter compressor; an internal heat exchanger which is prepared between an indoor heat exchanger and an outdoor heat exchanger, and generates superheated steam through heat exchange between a gas refrigerant and a liquid refrigerant; a first bypass pipe connected to the internal heat exchanger by being bypassed in the refrigerant pipe connecting the indoor heat exchanger and the outdoor heat exchanger; an electric motor expansion valve which is prepared in the first bypass pipe, and is controlled to prevent the gas refrigerant from being re-entered or entered into the internal heat exchanger; a superheated steam injection port for injecting the superheated steam to the dual inverter compressor by being prepared in a superheated steam guide pipe guiding the superheated steam generated in the internal heat exchanger o the dual inverter compressor; a bypass valve which is prepared in a second bypass pipe bypassed in the superheated steam guide pipe, and controls to inject or not to inject the superheated steam discharged from the internal heat exchanger to the dual inverter compressor; and a superheated steam blocking valve which is prepared in the superheated steam guide pipe, and controls to inject or not to inject the superheated steam to the dual inverter compressor.
