Refrigeration device

A refrigeration device comprising a refrigerant circuit (11) to which a compression unit (30), a heat source heat exchanger (22), a first utilization heat exchanger (83) and a second utilization heat exchanger (85, 93) connected in parallel to the heat source heat exchanger (22), and a flow path switching mechanism (70) that switches flow of refrigerant are connected,

• wherein the flow path switching mechanism (70) includes first to fourth flow paths (71, 72, 73, 74) and an opening and closing mechanism (V1, V2, V3, V4, 75, 76) that opens and closes a corresponding one of the flow paths (71, 72, 73, 74),
• a first connection point (C1) connecting an inflow portion of the first flow path (71) and an inflow portion of the second flow path (72) is connected to a discharge portion of the compression unit (30),
• a second connection point (C2) connecting an outflow portion of the first flow path (71) and an inflow portion of the third flow path (73) is connected to a gas-side end of the heat source heat exchanger (22),
• a third connection point (C3) connecting an outflow portion of the second flow path (72) and an inflow portion of the fourth flow path (74) is connected to a gas-side end of the second utilization heat exchanger (93), and
• a fourth connection point (C4) connecting an outflow portion of the third flow path (73) and an outflow portion of the fourth flow path (74), and a gas-side end of the first utilization heat exchanger (83) are connected to a suction portion of the compression unit (30).
