Abstract

Cette invention concerne une installation de refroidissement, laquelle comprend un condenseur, un évaporateur, ainsi qu'un dispositif de compression centrifuge à deux étages qui est alimenté par un moteur électrique comportant un système de refroidissement. L'entrée du condenseur est connectée à la sortie du dispositif, tandis que sa sortie est connectée par l'intermédiaire d'un premier et d'un second élément d'étranglement à l'entrée de l'évaporateur et du système de refroidissement. La sortie de l'évaporateur est connectée à l'entrée du dispositif, et la sortie du système de refroidissement est connectée à l'entrée du deuxième étage du dispositif. Le système de refroidissement comprend également une enveloppe de refroidissement dont la cavité se situe entre le stator et le corps. Cette installation comprend également un récipient de séparation, un échangeur thermique de récupération, ainsi qu'un clapet de régulation thermique. Ce clapet, qui est réglé en fonction de la pression et de la température d'un agent de refroidissement à son entrée dans l'enveloppe, est monté en série avec le récipient de séparation dans la ligne reliant l'entrée du condenseur à l'évaporateur. Le récipient de séparation est connecté par la phase gazeuse à un canal d'alimentation en agent de refroidissement. L'échangeur thermique est connecté à la ligne reliant la sortie du condenseur à l'entrée de l'évaporateur grâce au milieu de refroidissement et par l'intermédiaire du récipient de séparation. Le second élément d'étranglement se présente sous forme d'un clapet à réglage thermique, lequel est réglé en fonction de la pression et de la température de l'agent de refroidissement dans la ligne qui évacue ce dernier hors de l'enveloppe de refroidissement.
