摘要： A refrigerant relay device 1300 is provided with a casing 1310, a first refrigerant inflow opening 1360, a first refrigerant outflow opening 1350, and refrigerant inflow piping 1370. The casing retains liquid-phase refrigerant and gas-phase refrigerant. The liquid-phase refrigerant is made to flow into the casing through the first refrigerant inflow opening. The gas-phase refrigerant is made to flow out to the outside of the casing through the first refrigerant outflow opening. In the refrigerant inflow piping, one end is connected to the first refrigerant inflow opening and an opening 1371 is formed at the other end. The liquid-phase refrigerant flowing into the first refrigerant inflow opening is made to flow into the casing through the refrigerant inflow piping from the opening. The opening is positioned so as to face the bottom part 1311 of the casing.
