A flow path switching mechanism () includes first to fourth flow paths () and opening and closing mechanisms (V, V, V, V) that can each open and close a corresponding one of the flow paths (). A first connection point (C) connecting an inflow portion of the first flow path () and an inflow portion of the second flow path () is connected to a discharge portion of a compression unit (). A second connection point (C) connecting an outflow portion of the first flow path () and an inflow portion of the third flow path () is connected to a gas-side end of a heat source heat exchanger (). A third connection point (C) connecting an outflow portion of the second flow path () and an inflow portion of the fourth flow path () is connected to a gas-side end of a second utilization heat exchanger (). A fourth connection point (C) connecting an outflow portion of the third flow path () and an outflow portion of the fourth flow path (), and a gas-side end of a first utilization heat exchanger () are connected to a suction portion of the compression unit ().
