Abstract

La présente invention a trait à un dispositif de commande de capacité de réfrigération et à un appareil d'essai ainsi qu'à un procédé de commande de capacité de réfrigération utilisant le dispositif. Le dispositif de commande de capacité de réfrigération comprend un compresseur (2), un condensateur (5), un évaporateur (7), un organe de commande (1), un régulateur de pression (4), un organe d'étranglement (6), un tableau de commande (13) permettant de commander une soupape à gaz chaud et une soupape à gaz chaud (11). L'organe de commande est connecté à la soupape à gaz chaud (11) au moyen du tableau de commande (13) permettant de commander une soupape à gaz chaud ; le régulateur de pression (4) est disposé entre un orifice de sortie du compresseur (2) et un orifice d'entrée du condensateur (5) qui sont agencés dans le dispositif de réfrigération ; l'organe d'étranglement (6) est disposé entre un orifice de sortie du condensateur (5) et un orifice d'entrée de l'évaporateur (7) ; une extrémité de la soupape à gaz chaud (11) est disposée sur une canalisation entre l'orifice de sortie du compresseur (2) et l'extrémité avant du régulateur de pression (4) et son autre extrémité est disposée sur une canalisation qui se trouve entre l'organe d'étranglement (6) et un orifice d'entrée de l'évaporateur (7).
