Abstract
A steam injector including an introducing portion introducing a liquid flow of a refrigerant and a steam flow of the refrigerant; a mixing portion that has a shape with an internal cross-sectional area decreasing toward a moving direction of the liquid flow, and internally mixes the jet-like liquid flow with the steam flow to form a refrigerant flow; a throat portion formed on an outlet side of the mixing portion; and a diffuser portion that has a shape with an internal cross-sectional area increasing from the throat portion toward a moving direction of the refrigerant flow, and discharges the refrigerant flow at an increased pressure from a discharge portion. The throat portion has an internal cross-sectional area smaller than a critical cross-sectional area at which a discharge pressure of the refrigerant flow discharged from the discharge portion nonlinearly increases when the internal cross-sectional area of the throat portion is reduced.
