Definitions
- the invention relates to a freezer with one of Cold room accessible from above, by means of circulation cooling is cooled.
- the invention also relates to a cover for retrofitting such a freezer.
- Frozen goods are available in stores from above Freezers are stored and offered in which they are kept at freezing temperature. They are freezers known with so-called "quiet cooling", where heat sinks on the side walls of the cold room are arranged, so the cooling of the refrigerator takes place only from the cold room sides. The cooling effect is least where the heat radiation greatest cold losses occur, namely in the middle of the opening of the cold room. Compliance with a sufficient low temperature of frozen foods in the The middle of the opening is therefore very difficult.
- the ambient air constantly brings in moisture the cold room, the on the goods, the walls and the Heat sinks condensed and iced up there. This will make the Cooling capacity is reduced and there are further energy losses caused.
- the icing of the heat sinks can frequent defrosting required.
- the cold room is cooled by chilling.
- the Cold air enters through a cold air inlet in the cold room wall in the cold room.
- On the opposite cold room wall there is an air outlet through which air is sucked in and an air cooling device is supplied, the cold air generated.
- the cold air flowing at the top of the refrigerator forms an invisible curtain against the ambient air and cools the cold room from above, exactly where the largest Cold losses occur.
- Ambient air is caused by the cold air flow taken, which is why no ambient air and no Moisture gets into the refrigerator.
- the cold air Constantly taken warm ambient air must be at freezing temperature be cooled, which requires a lot of cooling energy.
- the humidity of the cold air condenses on the air cooling device which therefore often consumes heating energy must be defrosted. Outside of business hours Reduction of energy losses on thermal insulation covers the freezers are placed that have no view and no access allow on frozen goods.
- FR-A-941 248 discloses a chest freezer, one Has circulation cooling and which is covered with a cover.
- the cover has a large side access opening, which extends the entire length of the display case.
- Within the cover forms a moderately cooled air volume that cooler than the ambient air of the cover hood, but warmer than the horizontal cooling flow between cold air inlet and Cold air outlet is.
- the moderately cooled air volume within the Cover hood is heavier than the ambient air, so it passes through its own weight through the access opening from the cover is pushed out. While the moderately chilled air in the lower Part of the access opening is pushed out, flows in the upper one Area of the access opening heated ambient air into the Cover into it. In this way, new moist constantly penetrates and warm ambient air that is carried away by the cooling flow becomes.
- the object of the invention is to provide a device for the essential Reducing the energy consumption of a freezer create.
- the refrigerator In the freezer according to the invention is the refrigerator covered with a hood that is so high above the Cold air inlet protrudes that it has a substantially still volume of air above the cooling flow between the cold air inlet and outlet encloses.
- This volume of air forms an air cushion above the cooling flow, which on the one hand has a heat-insulating effect and on the other prevents the cold air with the cover hood washers comes into contact. This will make the disks kept at almost ambient temperature so that no condensation on the outside.
- the cover has at least one as transparent Disc trained lid through which the Frozen goods visible from the outside without opening the lid is.
- the lid is used to remove frozen goods opened briefly so that an exchange of air from ambient air with the air inside the hood only is very rarely possible. Even if the lid is Removal of frozen goods is opened standing air volume essentially obtained as it is colder than the ambient air and therefore does not rise.
- the cover gives the customer the impression that the frozen goods in the freezer carefully and well is kept protected and not the unrestricted random access is suspended. The frozen goods appears more valuable.
- the walls above the cold air inlet and outlet are opaque and usually pulled up to the lid.
- the walls of the cover can also be used as be transparent panes. This is the Frozen goods view as good as with one Freezer without any hood.
- Each disc is preferably a minimum distance apart 5 cm above the cold air outlet. Thereby it is ensured that each inside of the pane touches the warm, resting air volume, and not to the cold air, adjacent and therefore cannot fog up.
- panes of the transparent for visible light Lid and the walls of the cover can be attached to your Inside with a reflective heat radiation Coating should be provided. This will give off the heat radiation significantly reduced in the refrigerator. At the same time, the uncoated outside absorbs the heat radiation coming from the room. Thereby the lid or cover remains heated and one This prevents condensation.
- the cover of the cover is preferably as Sliding door formed, which, in contrast to hinged doors, when opening and closing the door only slight air turbulence and an exchange of ambient air and cooling air or dormant Air volume occurs only to a very small extent.

- the cover can also be used as a whole Cold room be designed removable, so that this for easier filling, maintenance or cleaning more accessible is.
- the cover can be cuboid or simple or be double-desk-shaped. Especially at the desk-like cover can be at the highest or another point of the cover a towering Writer for attaching markup and Billboards can be arranged.
- the cover preferably has an outside air inlet and a higher outside air outlet, a heater in the area of the inlet is arranged, heated by the inflowing outside air which is then along the inside of the lid flows to the outside air outlet.
- the through the Air flowing in from outside air inlet is at the heater warmed, it becomes lighter than them surrounding cooler air of the standing air volume, rises to the higher-lying outside air outlet and leaves through the outside air outlet the refrigerator again.
- a thermal air flow generated along the lid The flowed transparent lid warmed so that it is approximately Reached room temperature.
- the heating device can be used as a lighting device be formed, which on the one hand illuminates the cold room and on the other hand warms the incoming outside air.
- the lighting device can have a reflector, which reflects the light towards the refrigerator and at the same time forms a heating element.
- the The reflector only shines light on the Fridge directed so that one next to the freezer person standing by the lighting device can be dazzled.
- the refrigerated goods in the cold room are therefore clearly visible.
- the Reflector heat radiation of the lighting device, so that the air flowing into the lighting device on the side facing away from the lighting device of the reflector is heated and from there to the outside air outlet flows.
- the light source is preferably light in visible area (cold light) radiated into the cold room, that minimizes the heat input into the cold room.
- the lighting device is preferably a gas discharge lamp, that of an elongated housing is enclosed.
