REFRIGERATING DEVICE |
摘要 |
An opening/closing valve (70) is provided in an oil feed pipe (43). When a liquid refrigerant enters from an oil separator (22) into the oil feed pipe (43), the temperature of the liquid refrigerant depressurized by the opening/closing valve (70) is suddenly lowered. When the lowering amount of the temperature detected by a temperature sensor (73) exceeds a prescribed value, it is judged that the liquid refrigerant enters into the oil feed pipe (43), and the valve (70) is closed. |
