PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of accumulating oil at a place other than a gas-liquid separator, in a case where refrigerant is circulated in a refrigerant circuit in which refrigerant outflows from a liquid phase refrigerant outlet of the gas-liquid separator.SOLUTION: Since an oil separator 24 is provided in a refrigerant passage from a condenser 12 to a first expansion valve 28, refrigerant passing through the oil separator 24 is only or almost in a gas phase state in a case where a first refrigerant circuit for cooling is established in a refrigeration cycle device 10, and oil can be easily separated from the refrigerant. Accordingly, although oil is accumulated together with liquid phase refrigerant in a gas-liquid separator 17, oil can be accumulated in a place other than the gas-liquid separator 17 in a case where refrigerant is circulated in the first refrigerant circuit.SELECTED DRAWING: Figure 1 |
