  • the output of the evaporator for example in the direction of the refrigerator compartment in refrigerated-freezer combination devices can be designed so that there is a pipe run on the rear wall, the one Overflow of refrigerant in the downtime of the compressor at least reduced or even prevented.
  • An embodiment of an evaporator tube with overflow prevention has, for example, an on-side V-shape or U-shape at the upper end of which the outlet is from the freezer compartment of the associated evaporator. If refrigerant now arrives in this lying V-shaped evaporator tube section in the compressor standstill, gravity will counteract an overflow of refrigerant.

This allows the entire evaporator to be operated much more efficiently. By arranging the evaporator pipe sections siphons can be avoided and the noise during the compressor run time can be greatly reduced if necessary.

  • a one-piece solution can be created which, in contrast to fully connected evaporator plate sections, reduces bending effort and / or bending along one edge of two adjoining back sides of adjacent side walls of the freezer compartment is made easier, in particular more flexible.
  • air pockets can be reduced, if not completely avoided.
  • the cooling capacity can be improved on the inner container or in the storage spaces of the product.
  • evaporator plates Compared to known winding evaporators connected by webs invention evaporator plates have the advantage that depending on the version no Beauschlagung the rear wall of the inner container with a separate additional evaporator plate is necessary. Rather, an evaporator plate can be bent along the webs in the plane of the rear wall of the inner container.
  • a compressor stall time i. If the compressor of the refrigerant cycle system is not in operation and consequently the refrigerant is not conveyed through the compressor in the evaporator tube, for example, in refrigeration and freezing combination devices, the refrigerant from the evaporator tube associated with the freezer compartment can nevertheless flow into evaporator tube sections of an evaporator associated with the refrigeration compartment. This happens in particular when the same pressure has been set in the refrigerator compartment evaporator when the compressor is switched off as in the freezer compartment evaporator. This is also referred to as pressure equalization in the compressor stop time. After pressure equalization, there is typically a slow flow of refrigerant toward the compressor. Such a slow flow can be caused or at least intensified, for example due to absorption of refrigerant in the compressor oil or due to cooling of the compressor or its interior.
