Definitions

  • the present invention relates to a refrigerator with a storage compartment whose humidity is optimized for a particular type of stored goods.
  • the humidity that prevails in a storage compartment of a refrigeration device has an influence on the achievable storage time. While high levels of humidity are desirable, especially for the storage of leafy or root vegetables, to limit evaporation, for fruits that have a naturally evaporative-limiting shell, as well as for packaged chilled goods, dry storage is more beneficial, particularly to prevent mold growth.
  • the evaporator of a refrigerator Under normal operating conditions, the evaporator of a refrigerator is always colder than a storage compartment cooled by the evaporator. If the temperature difference is high enough to cool air from the storage compartment into contact with the evaporator below the dew point, condensation will settle on the evaporator. In conventional refrigerators with intermittently operated compressor is reliably at least during the operating times of the compressor, so that the relative humidity in a storage compartment of such a device does not reach high levels. In order to maintain a high level of humidity in an energy-efficient manner, the temperature difference between evaporator and storage compartment must be minimized.
  • variable-speed compressor is continuously operated with the exact power required to maintain a desired temperature in the storage compartment and the passage cross-section of an adjustable throttle is adjusted so that the pressure in the evaporator, the vapor pressure of the refrigerant in maintaining the target temperature of the storage compartment required evaporator temperature corresponds.

  • Second and fourth storage compartment can be identical. Then one and the same storage compartment can be selectively operated by exposure to cold air from the first evaporator, at high humidity or, h exposure to cold air from the second evaporator, at low humidity. Alternatively it can be provided between the second and fourth storage compartment an adjustable partition, which allows to adapt the sizes of the two storage compartments flexibly to the respective needs.

  • the flap 22 is in an intermediate position in which they are completely blocked 16 and 17, none of the flow lines and cold air from the evaporator 1 1 simultaneously to two compartments 1, 2 flows, however, this leads to a mixing of different humid air masses the compartments 1 and 2 in the evaporator chamber 14 and thus ultimately to an outflow of humidity from the cold storage compartment 2.
