If the freezer compartment 1 is activated, then refrigerant is injected into the freezer compartment or its evaporator 3 and is sucked directly out of it to the compressor 5.

There, however, it is passed into the freezer compartment evaporator 3 and sucked through the entire freezer compartment evaporator 3 through to the compressor 5.

  • the XOR device can not be optimized for both subjects. This was also not possible with the system according to FIG. 2.

To circumvent this last problem, in turn, a collector can be installed in the foam, but this leads to increased costs. If you put the amount of refrigerant not on the freezer, but on the refrigerator compartment, then the entire unit will be energetically less efficient.

Accordingly, the design of the condenser is made under different environmental conditions. If the conditions of use are not to be limited too much, one of the two valves can also be designed so that it is not tight above a certain storage pressure.

As a result, only so much refrigerant is available in the system in the case of a cooling fan cooling, as is necessary for the smaller cooling compartment evaporator 4. Thus, this evaporator 4 is not overcrowded and the intake manifold also not cooled too deep. The refrigerator compartment can be optimally adjusted.

Abstract

L'invention vise à mettre en oeuvre un appareil ménager combiné réfrigérateur/congélateur, de construction simple, dont chaque compartiment, au nombre d'au moins deux, peut être coupé individuellement. L'appareil frigorifique comporte à cet effet un circuit de refroidissement composé d'un compresseur (5), d'un condenseur (6) présentant une conduite de refroidissement (60) connectée sur sa première extrémité (61) au compresseur (5), d'une première soupape (11) connectée à la deuxième extrémité (62) de la conduite de refroidissement (60) du condenseur (6), d'un premier évaporateur (3) monté en aval de la première soupape (11) et connecté au compresseur (5), et d'un deuxième évaporateur (4). Une deuxième soupape (10) est montée entre les deux extrémités (61, 62) de la conduite de refroidissement (60) du condenseur (6) et est connectée sur sa deuxième sortie (10b) au deuxième évaporateur (4), le deuxième évaporateur (4) étant connecté côté sortie au compresseur (5). De manière avantageuse, il est ainsi possible de construire un système à double circuit de refroidissement comportant un seul compresseur, et du fait du stockage de fluide frigorigène dans la deuxième partie (6b) du condenseur (6), il est possible d'adapter la quantité de fluide frigorigène au condenseur et inversement, ce qui permet d'augmenter le rendement énergétique.
