Document Type and Number:
WIPO Patent Application WO/2019/171740
Kind Code:
A1
Abstract:
A dynamic compressor of the present disclosure is provided with: a rotating body which includes a rotating shaft and at least one impeller; a refrigerant flow passageway which is positioned around the rotating body and through which a gas-phase refrigerant flows; a main-flow passageway which is disposed in the rotating body and extends in an axial direction of the rotating body, and through which a liquid-phase refrigerant flows; and an injection flow passageway which is positioned in the rotating body, diverges from the main-flow passageway, and extends from the main-flow passageway to the refrigerant flow passageway, the injection flow passageway guiding the liquid-phase refrigerant from the main-flow passageway to the refrigerant flow passageway.
