- 3 is a view of a bearing shell with moisture-regulating elements,
- Fig. 6 is another view of the moisture-regulating element in the refrigeration compartment.
- Fig. 1 shows a refrigerator representative of a general refrigeration device 100.
- the refrigerator 100 has an upper refrigerator door and a lower refrigerator door.
- the refrigerator is used for example for cooling food as refrigerated goods and includes a refrigerant circuit with an evaporator, a compressor, a condenser and a throttle body.
- the evaporator is a heat exchanger in which after expansion the liquid refrigerant is absorbed by heat absorption from the medium to be cooled, i. the air inside the refrigerator is evaporated.
- the compressor is a mechanically operated component that draws refrigerant vapor from the evaporator and expels it at a higher pressure to the condenser.
- the condenser is a heat exchanger in which, after compression, the vaporized refrigerant is released by heat release to an external cooling medium, i. the ambient air is liquefied.
- the throttle body is a device for reducing the pressure by cross-sectional constriction.
- the refrigerant is a fluid used for heat transfer in the cryogenic system, at low temperatures and low pressure of the fluid Absorbs heat and at higher temperature and higher pressure of the fluid gives off heat, usually state changes of the fluid are included.
- the storage quality of refrigerated goods, such as fruits and vegetables, in the refrigeration device 100 is influenced mainly by the present in the refrigerator 100 factors of temperature and storage moisture, i. the relative humidity during storage.
- the storage moisture is for in the refrigerator 100 stored or unpacked refrigerated goods of crucial importance, since the bearing moisture interacts with the stored refrigerated goods.
- Humidity, humidity fluctuation and condensate formation are influenced by various factors such as the underlying refrigeration, storage volume, refrigerated goods, cold compartment temperature, wall temperature and storage quantity. In addition, these are influenced by the climatic conditions at the installation site of the refrigeration device 100 and specific conditions of use. Maintaining the quality of unpacked refrigerated goods can be ensured if the ideal for the refrigerated goods humid conditions prevail, which correspond to the equilibrium moisture content of many foods. In addition, large fluctuations in temperature and humidity should be avoided.
- Condensate accumulation or condensation in a storage area of refrigeration device 100 should be largely inhibited to curb microbial growth and prevent other product damage, such as texture loss or discoloration. In addition, a visually less appealing storage compartment should be avoided by condensate accumulation.
- Fig. 2 shows a schematic view of a membrane as a moisture-regulating element 103 in a storage area.
- the membrane has microchannels 15 through which water vapor diffuses along a temperature gradient or humidity gradient.
- the membrane is used to set a relative humidity in the storage area of more than 75%. Lower humidity in the storage area can cause the product to dry out and accelerate spoilage. Maintaining the food quality of unpackaged foods should be ensured by having ideal humidity conditions, for example between 85% to 95% relative humidity for fruits and 95% to 100% relative humidity for vegetables.
- the moisture-regulating element 103 serves to realize a humidity range of between 85% to 100% and to avoid or reduce a condensate attack.
- the moisture control is achieved by the use of a water vapor permeable membrane as a moisture-regulating element 103.
- the water vapor permeable membrane may be arranged in airtight closing or sealed bearing shells in the region of the lid and / or the bottom and / or the side walls, so that when exceeding a defined target moisture for the bearing shell, this excess moisture is increasingly dissipated through the membrane 103.
- One or more membranes 103 may be disposed in the shell region and are ideally removable or interchangeable.
- the hermetically sealed bearing shell ensures that the moisture released by the stored chilled goods is held within the bearing shell. As soon as the equilibrium moisture specific to the storage of the respective food has settled, for example 90 to 95% RH for vegetables, a large part of the excess moisture is removed via the membrane 103 into an external cooling section. The resulting amount of condensate in the bearing shell is reduced, without the dehumidification of the stored material is driven forward.
- the membrane 103 should have a given and adjustable permeability of water vapor. In addition, there should be a poor colonization by bacteria, a long-term stability and a cleaning resistance.
- the membrane 103 should be arranged on the cooling side, as a diffusion of water vapor or a water vapor transport through a temperature gradient and humidity gradient is favored.
- the bearing shell has a higher temperature than the overlying or surrounding the bearing shell cooling space and the humidity in the bearing shell is greater than in the refrigerator.
- a water-impermeable, but water-vapor-permeable membrane can be used. Microstructured, non-porous membranes and polymer coatings are best suited for the application.

- the coatings can be based on polyurethane PU or polyamide PA or silicone-based.
- the water vapor permeability (MVTR) of these materials is between 650-40000 g / m 2 24h.
- the membrane may be a ceramic membrane, for example Al 2 O 3 -based, and have a hydrophilic surface.
- the membrane may be a glass membrane formed, for example, by glass frits. A preparation is carried out by sintering glass granules having a pore diameter of 1-500 ⁇ .
- the ceramic membrane may have a hydrophilic surface.
- the membrane has a membrane specific adaptation to a Moisture Vapor Transmission Rate (MVTR) definition.
- MVTR Moisture Vapor Transmission Rate
- the Adaptation can be made depending on the air humidity range to be achieved between 85 ... 100% or to the respective refrigerated goods, such as a specific adaptation to fruit storage with an air humidity range of 85 to 95% or a vegetable storage with a humidity range of 95 to 100%.
- the adjustment can also be done depending on the volume of the vegetable dish, the temperature conditions compared to the refrigerated compartment, the humidity level in the refrigeration compartment in the refrigeration system or the average, expected loading of the vegetable shell.
- the required values for the water vapor permeability are calculated from a water release rate, which results from the quantity and type of the stored food and the available membrane surface.
- Membrane sizes for the bearing shell can be between 0.02m 2 to 0.08m 2 . Depending on the load between 50 to 1000 g / m 2 d are transported through the membrane.
- the membrane forms an alternative to complex mechanical solutions for moisture control, such as humidity controllers or ventilation slots.
- Fig. 3 shows a view of a bearing shell 109 with moisture-regulating elements 103.
