Title (EN) REFRIGERATOR OR FREEZER WITH ENHANCED EFFICIENCY
(FR) REFRIGERATEUR OU CONGELATEUR A EFFICACITE AMELIOREE
Abstract:
(EN) A refrigerator (10) or a freezer comprises a primary refrigeration system (11) which is augmented with a passive secondary refrigeration loop (15) having a condenser (30) in thermal contact with a primary fluid line (12) at the location between a primary compressor (16) and a primary condenser (18) and preferably placed outside a building so that the passive secondary refrigeration loop (15) provides cooling to the primary refrigeration system (11) when the outside temperature is sufficiently low The condenser (30) of the passive secondary refrigeration loop (15) is positioned above the points where the primary fluid line (12) connects with mlet (32) and outlet (34) lines of the secondary loop condenser (30)
(FR) L’invention concerne un réfrigérateur (10) ou un congélateur comprenant un système de réfrigération primaire (11) doté d’une boucle de réfrigération secondaire passive (15) comportant un condenseur (30) au contact thermique d’une conduite à fluide primaire (12) entre un compresseur primaire (16) et un condenseur primaire (18) et placée de préférence à l’extérieur d’un bâtiment, de façon à ce que la boucle de réfrigération secondaire passive (15) assure le refroidissement du système de réfrigération primaire (11) lorsque la température extérieure est suffisamment basse. Le condenseur (30) de la boucle de réfrigération secondaire passive (15) est placé au-dessus des points où la conduite à fluide primaire (12) se raccorde aux conduites d’entrée (32) et de sortie (34) du condenseur (30) de la boucle de réfrigération secondaire passive (15).
