Definitions

  • the present invention relates to a method for anytime Making defrosts on the evaporator of a refrigerator, in which the cooling of the in an access opening Refrigerated goods stored in a refrigerator by means of a normal operation cooled circulating air flow takes place, which in a Partially surrounding the refrigerator compartment, containing the evaporator Air duct is generated and through air inlets and outlets is led across the opening of the refrigerator, and a Refrigerators for performing this procedure, with a Cold room with access opening for receiving refrigerated goods as well as partially surrounding it, especially on three sides Air duct with evaporator and Air inlets and outlets for the recirculated air cooled in normal operation to the fridge.
  • Part of this process is that they are only outside retail can be used during business hours.
  • the object of the present invention was therefore a defrosting process, which for both the production of refrigerated furniture like is also suitable for retrofitting existing refrigeration units, also perform during normal business hours leaves and its use is not limited to freezers is, but for refrigerated shelves, refrigerators, refrigerated counters etc. can also be used.
  • the circulating air flow during the defrosting process so short-circuited that at the same time Blocking its operational flow paths reliably from the goods can be kept away.
  • the invention is suitable for new designs and retrofits.
  • the paths are recirculated Short circuit very short, which is particularly related to the energy consumption is cheap.
  • FIG. 1 shows the normal operation of a freezer 1.
  • the circulating air is cooled through the air inlet opening 10 in the cooling room 11, there cools the goods 13 and leaves with a higher temperature than when entering the refrigerator 11 through the air outlet opening 12.
  • the circulating air flows through the air path 9 to the evaporator 6 and gives their absorbed temperature and humidity there.
  • the Flow of the circulating air is caused by the fan 7 and this then passes through airway 8, through the air inlet opening 10, back into the cold room 11.
  • the blinds 18 become the air inlet openings 10 and the air outlet openings 12 closed.
  • the control flap 17 is opened and the circulating air is now through the room 14, which through the floor panel 4 and the introduced partition 15 with insulation 19 is formed, led to the heater 21.
  • the air warmed by the heater 21 thaws the ice or Ripening on the surface of the evaporator 6 and occurs again in room 14.
