PROBLEM TO BE SOLVED: To execute a cooling mode of high cooling performance in comparison with a conventional refrigeration cycle device, in a refrigeration cycle device switching cooling and heating modes by a receiver cycle.SOLUTION: A refrigeration cycle device includes: order changing means 13 for changing a refrigerant flowing order to a first outdoor heat exchange portion 16 and a receiver 14 at an upstream side of the refrigerant flow with respect to a second outdoor heat exchange portion 17. The order changing means 13 determines the receiver 14 first, and then the first outdoor heat exchange portion 16 as the refrigerant flowing order in a heating mode, and determines the first outdoor heat exchange portion 16 first and then the receiver 14 in a cooling mode. In the heating mode, the refrigerant successively flows to a compress 11→ a radiator 12→ the receiver 14→ first pressure reducing means 15→ the outdoor heat exchange portion 16→ the second heat exchange portion 17 in the heating mode, and a refrigerant circuit is switched in the cooling mode so that the refrigerant successively flows to the compressor 11→ the first outdoor heat exchange portion 16→ the receiver 14→ the second outdoor heat exchange portion 17→ second pressure reducing means 19→ an evaporator 20. |
