Definitions

  • the present invention relates to a method for operating a refrigeration device with a refrigerant circuit having two evaporators arranged parallel to one another, which cool thermally separated cold compartments, which may have different compartment temperatures, and a compressor, with which both evaporators can be acted upon separately from each other with refrigerant.
  • the present invention relates to such a refrigeration device for carrying out the operating method according to the invention.
  • a refrigerator-freezer combination device in which the refrigerating compartment and the freezer are arranged with arranged in parallel to each other, supplied by one and the same evaporator evaporators.
  • a solenoid valve allows the refrigerator compartment evaporator and the freezer compartment evaporator to be charged separately with refrigerant, which allows separate control of the temperature of both compartments.
  • a parallel connection of the refrigerator compartment evaporator and the freezer compartment evaporator entails that refrigerant which is vaporized during the downtime of the compressor due to the different temperatures of the two evaporators in the refrigerator compartment evaporator tends to flow and condense in the freezer compartment evaporator. If, subsequently, the compressor is switched on due to a cold request of the refrigerating compartment and refrigerant is circulated through the refrigerating compartment evaporator, the available quantity of refrigerant is small and the achievable cooling capacity is low, so that long compressor running times are required or, in extreme cases, even malfunctions can occur.
  • a section of the freezer evaporator in which refrigerant collects during the stoppage phase of the compressor, be designed such that this section, with regard to its refrigerant intake volume, is at least almost completely filled with liquid refrigerant is designed in the stoppage phase of the compressor, and so too placing, that when the compressor is turned on due to a refrigeration request of the refrigerating compartment, the refrigerant flowing through the refrigerant circuit of the controlled refrigeration compartment evaporator entrains the liquid refrigerant from said portion of the freezer compartment evaporator, thereby transferring it into the refrigerant circuit of the controlled refrigeration compartment evaporator.
  • the disadvantage is that the entrainment effect is the weaker the smaller the mass flow rate through the refrigerating compartment evaporator. That is, the more liquid refrigerant has collected in the freezer compartment evaporator, the smaller is the rate at which it can be withdrawn from the freezer compartment evaporator and fed back to the refrigerant flow through the refrigerated compartment evaporator. This also results in extended compressor run times and thus increased energy consumption of the refrigerator. A complete solution of the problem is not reached yet.

Abstract

La présente invention concerne un procédé pour faire fonctionner un appareil frigorifique doté d'un circuit frigorifique (15; 25; 35; 45) comportant deux évaporateurs (16, 17) placés parallèlement l'un à l'autre, lesquels évaporateurs refroidissent des compartiments frigorifiques (12, 13) séparés thermiquement l'un de l'autre et présentant différentes températures, ainsi qu'un compresseur frigorifique (22), au moyen duquel les deux évaporateurs (16, 17) peuvent être alimentés en fluide frigorigène de manière séparée. Selon l'invention, lorsqu'un premier compartiment (12) a besoin de froid, c'est d'abord l'évaporateur (17) du second compartiment (13) qui est alimenté en fluide frigorigène, au cours d'une phase de préparation, puis le circuit frigorifique est fermé vis-à-vis de l'évaporateur (17) du second compartiment (13) et seul l'évaporateur (16) du premier compartiment (12) est alimenté en fluide frigorigène. Au cours de cette phase de préparation, le fluide frigorigène liquide, enrichi dans l'évaporateur du second compartiment frigorifique, est expulsé, de sorte qu'il peut être réutilisé par l'évaporateur du premier compartiment frigorifique. Cela permet ainsi de remédier, de manière simple et économe en énergie, à un déplacement de fluide frigorigène vers l'évaporateur du plus froid des deux compartiments frigorifiques, lequel déplacement peut se produire pendant la phase d'arrêt du compresseur frigorifique.
