Abstract: An air conditioner is provided that may include a case having a supply flow path formed therein and through which outside air flows into an interior space, a first heat exchanger disposed on the supply flow path, in which refrigerant flows, and that exchanges heat between the air and the refrigerant, a second heat exchanger disposed downstream of the second heat exchanger on the supply flow path, in which refrigerant selectively flows, and that exchanges heat between the air and the refrigerant, and a refrigerant distributer configured to send the refrigerant to the first heat exchanger or the second heat exchanger.
