Zusammenfassung: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. Cet article décrit l'étude expérimentale d'un réfrigérateur àéjection de vapeur utilisant un éjecteur à buse primaire qui peut se déplacer dans l'axe de la chambroe de mélange. On a étudié les effets de la position de la buse sur le COP et la puissance frigorifique. On décrit le banc d'essai et la méthode; on présente les résultants qui mettent en évidence les avantages de l'utilisation d'un tel système.
