Definitions
- the invention relates to a method for treating the air in a cabinet for the storage and / or display of objects, whose walls, the "bottom and the DEK- kelkonstrutation the Vitrineninnenrau more or less enclose and wherein a forcibly introduced air flow to means of to Showcase interior connected, the air-conveying device is carried out while maintaining a low overpressure compared to the outside air, the air inflow being passed through a dust or gas protection filter using suitable means and the air humidity being adjusted and / or regulated, and a corresponding showcase for carrying it out of the procedure.
- DE-PS 38 05 212 C2 describes a display case for the storage and / or display of objects, in which the surrounding air in the interior of the display case is not only kept dust-free but also within the desired atmospheric humidity in order to protect the display objects. In addition, it is also possible to fill the interior with a neutral gas if the protection of the exhibited objects requires it.
- the object of the invention is therefore to provide a method of the type mentioned at the outset, in which the air flow supplied to the display case is made germ-free or to supplement the facilities of a display case of the type mentioned at the outset in such a way that a germ-free atmosphere is created in the interior of the display case.
- This object is achieved in a method or a device of the type mentioned at the outset in that the air inflow after the filtering is conducted into a container containing a liquid and in the liquid there is a catalyst by which the air is kept completely free of germs becomes.
- DE-PS 198 26 930 C2 describes an air-conditioned display case in which there is a flat heat exchanger in the interior of the display case and a collecting and humidifying tray arranged underneath it, the heat exchanger being connected to a refrigerator.
- the description shows that a fan allows the air to flow through the showcases connected in series in a targeted manner.
- the air conditioning of a showcase is also the subject of WO 01/84986 AI, the air in the interior of a showcase is forcibly fed to a device for dehumidification and heating / cooling.
- This device contains a hygroscopic agent, for example silica gel, which must be replaced as soon as it contains too much water.
- An air cleaning device in which the air is also sterilized is described in DE-OS 199 03 022 AI, the air being treated by means of an electrostatic device.
- Such a device should be versatile, such as use in the air ducts of air conditioning systems, the heated or cooled air being subjected to disinfection. How the disinfection of showcases should take place cannot be found in the description.
- the air humidity of the already germ-free air is set and / or regulated in connection with a cooling device.
- the catalyst according to the invention in cooperation with the liquid containing an additive, causes the air to be sterile, which is brought into contact with the liquid.
- Fig. 1 shows a section through a liquid container with a flat catalyst
- Fig. 2 shows a section through a liquid container with a sponge, which is surrounded by a catalyst.
- the container 2 shown in FIG. 1 is closed with a lid 10 and contains a liquid 7, for example distilled water.
- An air stream 5 freed of dust from the outside air is supplied to the space above the liquid 7, this can be done, for example, by passing a corresponding filter.
- Above the liquid 7, the air is enriched with moisture and the air treated in this way is fed to a cooling device 4, in which the moisture of this air is adjusted and regulated to a predetermined value.
- the air 6 treated in the manner described is then conveyed into the interior 1 of the display case by means of a pump, not shown.
- the pump is used to maintain a slight excess pressure in the interior 1 of the showcase, the pump only having to deliver the amount of air that is used to compensate for the amount of air escaping into the outside air through leaks in the showcase.
- the cooling device 4 and the pump (not shown) are controlled by a control device 3, to which sensors (not shown) for air pressure and moisture, which are arranged in the interior 1 of the display case, are connected, the pump depending on the specified air pressure value and depending on the value of the specified air humidity the cooling device 4 can be controlled accordingly.
- a monitoring device, not shown, for the fill level of the liquid 7 in the container 2 can also be connected to the control device 3, which then indicates with an acoustic and / or optical signal that the liquid supply in the container 2 must be supplemented.
- FIG. 2 shows a second embodiment, in which the dust-free air stream 5 is led into a sponge 11, the sponge 11 being encased by the grid network of the catalyst 8.
- the moisture-enriched air escapes from the sponge 11 and rises to the surface of the liquid 7.
- the further treatment of the cleaned and moisture-enriched air 6 then takes place in the manner already described.
- the sponge should be covered by the liquid 7 at least to such an extent that the catalyst 8 is at least below the surface of the liquid 7.
- the catalyst can also be in the form of wire, sheet metal, chips, powder, which ensures the formation of a sufficiently large effective area.
- the alloy used for the catalyst is composed of 10 to 80 '% by mass cobalt, 5- 50% by mass nickel and 5 to 20% by mass tungsten as well as 5 to 25 mass% of chromium, at temperatures in the range 250-1250 ° C is thermally treated for a period of 0.05 to 3 hours in an oxygen-containing atmosphere. Such a catalyst has a long-lasting high activity.
- the air in the interior 1 of the showcase is already sterile.
- a certain amount of hydrogen peroxide can also be added to the liquid 7, for example.
- the humidified and sterilized air is supplied to the interior 1 of the display case, whereby the air surrounding the exhibits in the display case also becomes germ-free after some time after a complete exchange of the air in the interior 1 as a result of the leaks has taken place and the air is open Duration is kept aseptic.
- the sterilized air is then fed to a cooling device 4 and then to the interior 1 of the display case.
- a cooling device 4 can be used to adjust the air humidity and / or the temperature of the air in the interior 1 of the showcase, which is done by heating or cooling the air. It is also conceivable, if the cooling device 4 is designed accordingly, i.
- the cooling device 4 is to be combined with the device according to the invention for the disinfection of the air by the water both for setting air humidity and / or Temperature and is used by the additive in conjunction with the catalyst to disinfect the air.
- the air 5 treated with regard to the absence of dust can now either be completely removed from the outside air of the display case, but it is also conceivable to remove part of this air from the interior 1 of the display case, as a result of which the air exchange in the interior 1 is accelerated.
- the described devices for humidifying and disinfecting the air in the interior 1 of a showcase can be closed Device can be accommodated individually in a display case. However, it is also conceivable to provide a common device for a plurality of showcases, to which only the interior 1 with the one or more air lines and with the sensors is connected.
- the invention is applicable both to showcases in which objects are put on display and to those showcases which are used only for the storage of objects.
