Abstract

An outdoor device for an air conditioner is provided that may include a compressor, a flow switch provided at an outlet-side of the compressor to switch a flow direction of a refrigerant according to a cooling operation or a heating operation, and an outdoor heat exchanger connected to the flow switch. The outdoor heat exchanger may include first to third heat exchangers, each of which may include a refrigerant tube through which the refrigerant may flow, the first to third heat exchangers being connected to each other in parallel during a heating operation and in series during a cooling operation, a first branch that branches the refrigerant into a first distribution tube, which may be directed to the first and second heat exchangers, and a second distribution tube which may be directed to the third heat exchanger, a second branch that branches the refrigerant branched from the first branch into a first branch tube, which may be directed to the first heat exchanger and a second branch tube, which may be directed to the second heat exchanger, and a first valve provided in the first distribution tube.
