A flow channel switching mechanism (70) has: first to fourth flow channels (71, 72, 73, 74); and opening/closing mechanisms (V1, V2, V3, V4, 75, 76) capable of opening and closing the respective flow channels (71, 72, 73, 74). A first connection point (C1), for connecting an inflow part of the first flow channel (71) to an inflow part of the second flow channel (72), is connected to a discharge part of a compression part (30). A second connection point (C2), for connecting an outflow part of the first flow channel (71) to an inflow part of the third flow channel (73), is connected to a gas-side end of a heat-source heat exchanger (22). A third connection point (C3), for connecting an outflow part of the second flow channel (72) to an inflow part of the fourth flow channel (74), is connected to a gas-side end of a second utilization heat exchanger (85, 93). A fourth connection point (C4), for connecting an outflow part of the third flow channel (73) to an outflow part of the fourth flow channel (74), and a gas-side end of a first utilization heat exchanger (83) are connected to an intake part of the compression part (30).
