PROBLEM TO BE SOLVED: To provide a refrigerant cycle device having a reversible flow of refrigerant, avoiding a sleeping phenomenon of oil in a heat exchanger. SOLUTION: The refrigerant cycle device comprises a rotary compressor 10, an outdoor heat exchanger 110, a expansion valve 111 and an indoor heat exchanger 114. It has a cooling cycle, where the refrigerant discharged from the rotary compressor 10 flows into the outdoor heat exchanger 110, the expansion valve 111 and the indoor heat exchanger 114 in sequence, and a heating cycle, where the refrigerant discharged from the rotary compressor 10 flows into the indoor heat exchanger 114, the expansion valve 111 and the outdoor heat exchanger 110 in sequence. In both the cooling cycle and the heating cycle, a refrigerant flow path is changed over so that the direction of the refrigerant flowing in the outdoor heat exchanger 110 is the same as that of the refrigerant flowing in the indoor heat exchanger 114.
