Abstract: An air conditioner includes a compressor, a flow switching part, an outdoor heat exchanger including a plurality of refrigerant tubes for guiding the refrigerant heat exchanged with outdoor air, a main expansion valve disposed at one side of the outdoor heat exchanger, a first inlet/outlet tube extending from the flow switching part to the outdoor heat exchanger, and a second inlet/outlet tube extending from the outdoor heat exchanger to the main expansion valve. The outdoor heat exchanger includes a header defining a flow space for the refrigerant, the header including an upper header and a lower header, a check valve disposed between the upper header and the lower header to guide the refrigerant to flow in one direction, and a bypass tube extending from the lower header to the second inlet/outlet tube to guide a discharge of a liquid refrigerant existing in the lower header.
