Abstract

Système de réfrigération utilisant un réfrigérant pour refroidir un liquide. Il comprend un compresseur 11 permettant d'augmenter la température et la pression du réfrigérant gazeux; un condenseur 22 relié au compresseur, et où le réfrigérant change d'état pour se transformer de gaz en liquide; un économiseur thermique 28 relié au condenseur, et dans lequel le réfrigérant liquide est partiellement détendu, le réfrigérant détendu absorbant de la chaleur du reste du réfrigérant liquide; un économiseur-condenseur 42 pour condenser le gaz détendu en un réfrigérant liquide; et un évaporateur 36 pour refroidir le liquide, ledit évaporateur recevant le réfrigérant liquide de l'economiseur instantané et de l'économiseur-condenseur, et évacuant le réfrigérant gazeux vers le compresseur. Applications domestiques notamment.
