Air conditioner and method of controlling the same

摘要

An air conditioner includes a compressor (120), a first heat exchanger (220), and a first pipe (112) configured to allow refrigerant to flow from the first heat exchanger (220). A bypass pipe (181) is branched off from the first pipe (112) and is configured to expand refrigerant flowing through the bypass pipe (181). A second heat exchanger (182) is configured to allow the expanded refrigerant of the bypass pipe (181) to heat-exchange with the refrigerant flowing along the first pipe (112). A second pipe (111) couples the second heat exchanger (182) to the compressor (120) so that the refrigerant expanded by the bypass pipe (181) and heat-exchanged at the second heat exchanger (182) can be introduced into the compressor (120).
