Refrigeration cycle device

Abstract

Refrigeration cycle device (100) includes heat exchanger (50) having a plurality of heat transfer fins (2) and a plurality of heat transfer pipes (1), and refrigerant flow adjustment part (5) that adjusts a flow direction of a refrigerant. Heat exchanger (50) is divided into first heat exchanger section (3) and second heat exchanger section (4). Refrigerant flow adjustment part (5) adjusts a refrigerant flow such that air flow direction (8) and refrigerant flow direction (9, 10) are opposed to each other in first heat exchanger section (3) in either of a case where heat exchanger (50) functions as an evaporator and a case where the heat exchanger functions as a condenser.
