PROBLEM TO BE SOLVED: To keep a high ejector efficiency regardless of flow rates of a refrigerant and kinds of the refrigerants. SOLUTION: A ratio (D2/D1) of an equivalent diameter D2 of a mixing portion 420 to an equivalent diameter D1 of a nozzle 410 is 1.05-10. Accordingly, the ejector type refrigerating cycle is operated while keeping the high ejector efficiencyηe. COPYRIGHT: (C)2011,JPO&INPIT
