Claims (9)

  1. Appareil de congélation comprenant au moins deux compartiments de congélation placés à l'intérieur de son boítier calorifuge, séparés thermiquement l'un de l'autre, dont chacun est réfrigéré par un évaporateur, lesquels sont alimentés en réfrigérant par un compresseur,
    caractérisé en ce que
    les compartiments de congélation (12, 13) sont munis de différents volumes utiles et en ce que les évaporateurs (15, 19) servant à leur réfrigération sont raccordés en série, quant au flux, l'évaporateur (19) servant à la réfrigération du compartiment de congélation (13) de volume utile plus grand pouvant être découplé du circuit frigorifique par deux moyens de commande et servant de réservoir pour le réfrigérant liquide.
  2. Appareil de congélation suivant la revendication 1, caractérisé en ce que l'un des moyens de commande est exécuté comme une électrovanne à trois/deux voies (17) commandable électriquement, installée en montage en série par rapport aux évaporateurs (15, 19) et en ce que l'autre moyen de commande est exécuté comme une vanne d'arrêt (21) commandable électriquement, placée à la sortie de l'évaporateur (19) prévu dans le compartiment de congélation (13) de volume utile plus grand.
  3. Appareil de congélation suivant la revendication 1, caractérisé en ce que les deux moyens de commande sont formés comme des électrovannes à trois/deux voies (17) commandables électriquement, l'une étant placée en montage en série entre les évaporateurs (15, 19) et l'autre électrovanne à trois/deux voies (17) étant placée, côté sortie, sur l'évaporateur (19) destiné à la réfrigération du compartiment de congélation (13) de volume utile plus grand.
  4. Appareil de congélation suivant l'une quelconque des revendications 1 à 3, caractérisé en ce que l'opération de commutation des moyens de commande (17, 21) pour le découplage de l'évaporateur (19) destiné à la réfrigération du compartiment de congélation (13) de volume utile plus grand a lieu à peu près dans le même temps.
  5. Appareil de congélation suivant l'une quelconque des revendications 1 à 4, caractérisé en ce que les moyens de commande (17, 21) sont commandables électriquement par un circuit d'évaluation électronique, lequel commute les moyens de commande (17, 21) pour le couplage resp. le découplage de l'évaporateur (19) dans le compartiment de congélation (13) de volume utile plus grand en fonction de la température dans ce compartiment.
  6. Appareil de congélation suivant l'une quelconque des revendications 1 à 5, caractérisé en ce que les moyens de commande (17, 21) peuvent être mis dans la position de commutation servant au découplage de l'évaporateur (19) destiné à la réfrigération du compartiment de congélation (13) de volume utile plus grand par l'actionnement manuel d'un commutateur électrique.
  7. Appareil de congélation suivant l'une quelconque des revendications 1 à 6, caractérisé en ce que les évaporateurs (15, 19) servant à la réfrigération des compartiments de congélation (12, 13) sont formés comme des évaporateurs en tube en fil disposés en étages.
  8. Appareil de congélation suivant l'une quelconque des revendications 1 à 6, caractérisé en ce que les évaporateurs (15, 19) servant à la réfrigération des compartiments de congélation (12, 13) sont formés comme des platines d'évaporateur essentiellement à surface fermée.
  9. Appareil de congélation suivant l'une quelconque des revendications 1 à 8, caractérisé en ce que le compartiment de congélation (12) de volume utile plus petit est placé dans le boítier (11) de l'appareil de congélation (10), au-dessus du compartiment de congélation (13) de volume utile plus grand.
