Definitions

  • the invention relates to a method for the treatment of air in a display case for the storage and / or display of objects whose walls, their bottom and their Dekkelkonstrutation the showcase interior more or less enclose and in which a compulsorily initiated air flow by means of a connected to the showcase interior, the air-conveying device takes place in compliance with a low overpressure relative to the outside air, wherein the air flow is conducted before introduction by suitable means via a dust or gas protection filter and the humidity of the same adjusted and / or regulated and a corresponding display case for performing the method.
  • the object of the invention is therefore to provide a method of the type mentioned, in which the showcase supplied air flow is made germ-free or to complement the facilities of a showcase of the type mentioned in that in the interior of the showcase creates a germ-free atmosphere.
  • This object is achieved in a method or a device of the type mentioned in that the air flow is conducted after filtering in a container containing a liquid and that in the liquid is a catalyst through which the air is kept completely free of germs becomes.
  • the air conditioning of a showcase is also the subject of WO 01/84986 A1 , while the air of the interior of a showcase is forcibly fed to a device for dehumidification and heating / cooling.
  • This device contains a hygroscopic agent, such as silica gel, which must be replaced as soon as it contains too much water.
  • An air cleaning device in which also a sterilization of the air is carried out in the DE-OS 199 03 022 A1 described, while the air is treated by means of an electrostatic device.
  • Such a device should be versatile, such as the use in the air ducts of air conditioning systems, wherein the heated or cooled air is subjected to a sterilization. How the sterilization should be done in showcases, the description can not be found. In the present invention, however, the humidity of the already germ-free air is adjusted in conjunction with a cooling device and / or regulated.
  • the catalyst according to the invention in cooperation with the liquid containing an additive, effects a sterility of the air which is brought into contact with the liquid.
  • the in Fig. 1 shown container 2 is closed with a lid 10 and contains a liquid 7, for example, distilled water.
  • a liquid 7, for example, distilled water for example, distilled water.
  • the space above the liquid 7, a freed from the dust of the outside air flow 5 is supplied, this can be done for example by passing a corresponding filter.
  • Above the liquid 7, the air is enriched with moisture and the thus treated air is supplied to a cooling device 4, in which the humidity of this air is adjusted to a predetermined value and regulated.
  • the treated in the manner described air 6 is then transported by means of a pump not shown in the interior 1 of the showcase.
  • the pump is used to maintain a slight overpressure in the interior 1 of the showcase, the pump has to promote only that amount of air, which serves to compensate for leaks from the showcase in the outside air amount of air.
  • the cooling device 4 and the pump, not shown, is controlled by a control device 3, to which not shown, mounted in the interior 1 of the showcase sensors for air pressure and humidity are connected, depending on the predetermined air pressure value the pump and depending on the value of the predetermined air humidity the cooling device 4 are controlled accordingly.
  • a monitoring device, not shown, for the filling level of the liquid 7 in the container 2 may also be connected to the control device 3, which then indicates with an acoustic and / or optical signal that the liquid reservoir in the container 2 must be supplemented.
  • a catalyst 8 in the form of a flat surface of a lattice network, which is between two flat surfaces each of a protective grid 9, while ensuring that the catalyst is always covered by the liquid 7.
  • Fig. 2 a second embodiment is shown, in which the dust-free air stream 5 is guided into a sponge 11, wherein the sponge 11 is covered by the lattice network of the catalyst 8.
  • the moisture-enriched air escapes the sponge 11 and rises to the surface of the liquid 7.
  • the further treatment of the purified and moisture-enriched air 6 then takes place in the manner already described.
  • the sponge should be at least as far covered by the liquid 7, that at least the catalyst 8 is below the surface of the liquid 7.
  • the catalyst may also be in the form of wire, sheet, chips, powder, which ensures the formation of a sufficiently large effective area.
  • the alloy used for the catalyst consists of 10 to 80% by mass of cobalt, 5 to 50% by mass of nickel and 5 to 20% by mass of tungsten and 5 to 25% by mass of chromium, which are at temperatures in the range from 250 to 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 humidified and sterilized air is supplied to the interior 1 of the showcase, whereby the ambient air surrounding the exhibits in the showcase germ-free after some time after a complete exchange of air in the interior 1 due to the leaks has taken place and the air Duration is kept germ-free.
  • the sterilized air is then fed to a cooling device 4 and then the interior 1 of the showcase.
  • a cooling device 4 can be used for adjusting 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.
  • the cooling device 4 with appropriate design of the cooling device 4, that is, if in this according to the prior art in conjunction with water, the setting of a predetermined humidity and / or temperature of the air, the cooling device 4 with the inventive device for sterilizing the air by using the water both for adjusting the humidity and / or temperature and by the additive in connection with the catalyst for the sterilization of the air.
  • the treated in terms of dust-free air 5 can now either completely removed from the outside air of the showcase, but it is also conceivable to remove a portion of this air the interior 1 of the showcase, whereby the air exchange in the interior 1 is accelerated.
  • the described devices for humidification and sterilization of the air in the interior 1 of a showcase can be closed Device housed individually in a showcase. However, it is also conceivable to provide a common device for several showcases, to which only the interior 1 is connected to the one or more air lines and the sensors.
  • the invention is applicable both to showcases in which objects are displayed, as well as to such showcases, which serve only for the storage of objects.
