Abstract
In an ejector cycle system, a mixing portion of an ejector has a length in a refrigerant flow direction and an equivalent diameter, and a ratio of the length to the equivalent diameter of the mixing portion is equal to or smaller than 120. Further, a ratio of the equivalent diameter of the mixing portion to an equivalent diameter at an outlet of a nozzle of the ejector is in a range of 1.05-10. Accordingly, the ejector cycle system operates while a high ejector efficiency is maintained.
