Definitions

  • the invention concerns a method for air treatment in a display cabinet for the storage and/or display of objects, whose walls, floor and roof structure more or less enclose the inside space of the display cabinet and in which a forced inflow of air from an air delivery system connected to the inside space of the cabinet maintains a slight excess pressure compared with the air outside it, this airflow passing through suitable dust or gas filtration means before entering the cabinet and having its air humidity adjusted and/or controlled, and a corresponding display cabinet for implementing the method.
  • DE-PS 38 05 212 C2 describes a cabinet for the storage and/or display of objects, in which, for the protection of the objects displayed, the air surrounding them inside the cabinet is kept not only free from dust but also within a desired range of air humidity. It is also possible to fill the inside space with a neutral gas, if this is required for the protection of the objects displayed.
  • the purpose of the present invention is to indicate a method of the type mentioned above, in which the airflow passing into the display cabinet is rendered germ-free, and to supplement the equipment of a display cabinet of the type mentioned at the start, in such manner that a germ-free atmosphere is produced inside the cabinet.
  • DE-PS 198 26 930 C2 describes a climate-controlled display cabinet, in which a flat heat exchanger is in the inside space of the cabinet and a collecting and humidifying tray is arranged under it, the heat exchanger being connected to a refrigerating machine. From the description it can be seen that by means of a fan, a controlled flow of air can be passed through a number of cabinets connected in series. In contrast, in the present invention the controlled airflow first passes into a container holding a liquid and then to a cooler.
  • the climate-control of a display cabinet is also the object of WO 01/84986 A1, in which the air inside a display cabinet is propelled through a dehumidifying and heating/cooling device.
  • the said device contains a hygroscopic medium, for example silica gel, which has to be replaced as soon as it has absorbed too much water.
  • the catalyser In collaboration with the liquid containing an additive, the catalyser according to the invention frees the air that has been brought into contact with the liquid from germs.
  • FIG. 1 Section through a container of liquid with a flat catalyser
  • FIG. 2 Section through a container of liquid with a sponge, which is surrounded by a catalyser
  • the container 2 shown in FIG. 1 is closed by a cover 10 and contains a liquid 7 , for example distilled water.
  • a liquid 7 for example distilled water.
  • an airflow 5 freed from the ambient air dust, for example by passing through an appropriate filter.
  • the air picks up moisture, and the air so treated is passed into a cooling device 4 in which the humidity of this air is adjusted and regulated to a specified value.
  • the air 6 treated in this way is then passed by means of a pump (not shown) into the inside space of the display cabinet.
  • the pump serves to maintain a slight excess pressure in the inside space 1 of the cabinet, and only has to deliver an amount of air sufficient to make up for any air that escapes to the outside by leaking out of the cabinet.
  • the cooling device 4 and the pump are controlled by a control unit 3 to which sensors (not shown) for air pressure and humidity positioned in the inside space 1 of the display cabinet are connected, so that the pump is correspondingly controlled as a function of the specified air pressure, and the cooling device 4 as a function of the specified air humidity.
  • a monitoring device (not shown) for the filling level of liquid 7 in the container 2 can also be connected to the control unit 3 , and by means of an acoustic and/or visual signal this indicates when the liquid reserve in the container 2 should be topped up.
  • catalyser 8 At the bottom of the container 2 in the liquid 7 there is a catalyser 8 in the form of a flat grid held between the two flat surfaces of respective protective gratings 9 , and it must be ensured that the catalyser is covered by liquid 7 at all times.
  • FIG. 2 shows a second embodiment in which the dust-free airflow 5 is passed into a sponge 11 , the sponge 11 being enveloped by the grid of the catalyser 8 .
  • the humidified air escapes from the sponge 11 and rises to the surface of the liquid 7 .
  • the further treatment of the cleaned and humidified air 6 then takes place in the manner already described.
  • the sponge must be covered by the liquid 7 at least sufficiently for the catalyser 8 to be below the surface of the liquid 7 .
  • the catalyser can take any form such as wire, sheet, chips or powder, which will ensure the presence of a sufficiently large active surface area.
  • the alloy used for the catalyser consists of 10 to 80 mass-% of cobalt, 5 to 50 mass-% of nickel, 5 to 20 mass-% of tungsten and 5 to 25 mass-% of chromium, heat treated in an atmosphere containing oxygen for 0.05 to 3 hours at temperatures in the range 250° to 1,250° C. Such a catalyser remains highly active for prolonged periods.
  • the collaboration of the catalyser 8 with water as the liquid 7 already frees the air in the inside space 1 of the display cabinet from germs.
  • the liquid 7 can for example also contain a certain amount of hydrogen peroxide.
  • the humidified and germ-free air is passed into the inside space 1 of the display cabinet, whereby the air surrounding the displayed objects in the cabinet also becomes free from germs since after some time the air in the inside space 1 will have been completely renewed due to leaks, and the air can then be kept continually free from germs.
  • the germ-free air is then passed into a cooling device 4 and thence to the inside space 1 of the display cabinet. It is also conceivable, however, to pass the air first into a cooling device 4 and only then to subject it to the treatment for germ removal.
  • the cooling device 4 can serve to adjust the air humidity and/or temperature of the air in the inside space 1 of the cabinet, by heating or cooling the air. In this it is also conceivable, if the cooling device 4 is of appropriate design, i.e.
  • a specified air humidity and/or air temperature can be established, to combine the cooling device 4 with the device according to the invention for eliminating germs from the air, since the water serves both to adjust the air humidity and/or temperature and also, by virtue of the additive in combination with the catalyser, to eliminate germs from the air.
  • the air 5 treated to remove dust can all come from the air outside the display cabinet, but it is also conceivable for some of this air to come from the inside space 1 of the cabinet, whereby the air replacement in the inside space 1 is accelerated.
  • the devices described for humidifying and eliminating germs from the air in the inside space 1 of a display cabinet can be positioned individually as closed units inside the cabinet. It is also conceivable, however, if there are several display cabinets, to provide a common device to which only the inside space 1 with the air duct(s) and with the sensors is connected.
  • the invention can be used both for display cabinets in which objects are set out for display, and with cabinets serving only for the storage of objects.
