PROBLEM TO BE SOLVED: To perform a highly efficient operation in a wide rotational frequency range, and to reduce power consumption in a long-term view.SOLUTION: A refrigeration cycle device mounts a compressor including: a stator in which a plurality of pieces of coil units 23U, 23V, 23W including a plurality of pieces of coils 231, 232 are arranged; and a rotor in which a plurality of poles are formed. It also includes a control unit 36 which switches a connection state of the coils 231, 232 included in each of the coil units 23U, 23V, 23W, and the control unit 36 switches the connection state of the coil units 23U, 23V, 23W according to an operation condition.SELECTED DRAWING: Figure 4 |
