Abstract

L'invention porte sur une pompe volumétrique (4) couplée magnétiquement à un moteur (42) placé dans un système de canalisations (60) parallèle à la direction de la ligne de liquide d'un système de réfrigération (voir la figure). Ledit système de canalisations renferme également une vanne de régulation de pression régulant l'accroissement de pression de la ligne de liquide sous son action; en outre une soupape d'arrêt (47) est placée dans la ligne de liquide pour maintenir le différentiel d'accroissement de pression. Ce système en parallèle (60) permet d'accroître la pression de la ligne de liquide d'une valeur prédéterminée constante indépendamment des variations de débit du réfrigérant. Il permet de plus d'empêcher l'obstruction de la ligne de liquide en cas de panne de la pompe. L'invention porte également sur tout procédé d'introduction contrôlée d'un fin brouillard d'eau dans le flux d'air de condenseurs à refroidissement par air pour simuler les performances de condenseurs à évaporation, en abaissant la température de l'air incident pour la faire passer d'un niveau de température de thermomètre sec à un niveau de température de thermomètre mouillé, ce qui se traduit par une réduction de la température et de la pression dans la système de condensation. La pompe objet de la présente invention comprend un aimant extérieur d'entraînement (200), une cuvette fixe (200), un joint torique (202), un aimant interne entraîné (203), un rotor (204), des ailettes (205), un second joint torique (206) et une tête de laiton (207).
