Abstract
Le liquide réfrigérant produit dans le condenseur d'un circuit de réfrigérant produit dans le condenseur d'un circuit de réfrigération est introduit dans un dispositif de détente (28) qui permet au liquide réfrigérant sous haute pression de pénétrer dans l'enceinte (12) d'un moteur (158) d'entrainement du compresseur (14). Une partie du liquide se vaporise instantanément en un gaz ayant une pression comprise entre les pressions d'aspiration et de refoulement du compresseur. Le fluide réfrigérant restant liquide est introduit dans une chemise (108) entourant le stator (120) du moteur.
