A small capacity steam-ejector refrigerator: experimental investigation of a system using ejector with movable primary nozzle
Abstract This paper describes an experimental study of a steam-ejector refrigerator using an ejector with a primary nozzle that could be moved axially within the mixing chamber section. The effects on coefficient of performance and cooling capacity produced by adjusting the position of the nozzle were studied. The experimental rig and method are described and results are presented which clearly show the benefit of using such a primary nozzle.
