Abstract: The evaporator unit includes an ejector, a discharge-side evaporator, and a suction-side evaporator. The discharge-side evaporator includes discharge-side tubes and a discharge-side tank. The discharge-side tank defines a discharge-side distribution chamber therein which distributes refrigerant to the discharge-side tubes. A partition plate is disposed in the discharge-side distribution chamber and divides the discharge-side distribution chamber into an ejector-side distribution chamber and a tube-side distribution chamber. The partition plate includes a communication hole through which the ejector-side distribution chamber and the tube-side distribution chamber are in fluid communication with each other. The partition plate includes a first portion, a second portion, a third portion, a fourth portion, and a fifth portion. The communication hole has an open area that is larger in each of the first portion, the third portion and the fifth portion than in each of the second portion and the fourth portion.
