    Abstract: PURPOSE: A refrigerant cycle device is provided to improve the coefficient of performance during cooling operation while suppressing a temperature rise in a hermetic container by using an intermediate cooling circuit for permitting heat radiation of a refrigerant discharged from a first rotating compression element during cooling operation. CONSTITUTION: A compressor(10) has first and second rotating compression elements(32,34) in a hermetic container(12). An intermediate cooling circuit(150) introduces a refrigerant compressed by the first rotating compression element into the second rotating compression element, and radiates heat of the refrigerant discharged from the first rotating compression element. A three-way valve(162) opens a flow path in the intermediate cooling circuit during cooling operation.
