Abstract

Système de réfrigération à compression de vapeur, avec compresseur Il, condenseur 22, économiseur de condensation 28 et évaporateur 36 formant une boucle primaire de réfrigérant. Un second compresseur 17 et un économiseur thermique 52 forment une boucle secondaire de réfrigérant. Dans une variante, le réfrigérant gazeux d'un économiseur thermique est condensé par un économiseur-condenseur, puis soumis à vaporisation partielle instantanée dans un économiseur de condensation. Le réfrigérant gazeux de l'économiseur de condensation est recomprimé dans le second compresseur, puis recondensé dans l'économiseur-condenseur. Le réfrigérant recondensé est dirigé vers l'économiseur de condensation avec le réfrigérant liquide restant en provenance du condenseur. Applications domestiques notamment.Vapor compression refrigeration system, with compressor II, condenser 22, condensate economizer 28 and evaporator 36 forming a primary refrigerant loop. A second compressor 17 and a thermal economizer 52 form a secondary refrigerant loop. In a variant, the gaseous refrigerant of a thermal economizer is condensed by an economizer-condenser, then subjected to instantaneous partial vaporization in a condensation economizer. The gaseous refrigerant from the condenser economizer is recompressed in the second compressor, then recondensed in the economizer-condenser. Recondensed refrigerant is directed to the condensation economizer with the remaining liquid refrigerant from the condenser. Domestic applications in particular.
