Definitions

  • the invention relates to a refrigerator with a product space to be cooled, a refrigeration unit, which contains a refrigerant compressor, a refrigerant evaporator and a device for conveying cooled air, and with a ceiling structure covering the product space, which has an outlet opening for cooled air.
  • Refrigerated cabinets used in the food sales area serve on the one hand for storage and on the other hand for the presentation of goods that have to be stored below the ambient temperature.
  • freezers are used in particular for frozen products. Since the chests only allow a relatively unfavorable presentation of goods - the customer cannot see from a distance what is in the chest - glazed refrigerated shelves have already been used for frozen goods, in which the goods are arranged behind a glass door. However, it has been shown that there is an inhibition threshold for the customer in such a refrigerator to open the glass door, so that frequently the desired turnover is not achieved.
  • certain measures for heat insulation are indispensable, since otherwise the goods in the refrigerated cabinet will after some time heat up to the maximum permissible temperature.
  • the invention is therefore based on the object of developing a refrigerator of the type mentioned at the outset which enables a particularly clear presentation of goods and which is readily accessible to the customer.
  • the refrigeration unit is constructed from two units arranged one above the other on the rear side of the goods space, one of which contains the refrigerant compressor and the other contains the refrigerant evaporator and the device for conveying air.
  • the refrigerated cabinet according to the invention is constructed from components which are arranged one above the other, ie in a vertical plane.
  • the refrigeration cabinet according to the invention has no all-round heat-insulated goods space.
  • the refrigerated cabinet according to the invention is therefore significantly smaller, lighter and more compact than previous refrigerated cabinets.
  • the refrigerated cabinet according to the invention is particularly space-saving and movable.
  • the refrigerator is therefore suitable to be placed in the sales room only when needed, for example on busy days, and otherwise to be pushed aside.
  • the relatively open goods area which is only closed at the rear by the units containing the refrigeration unit, enables a clear arrangement of the goods.
  • Another advantage is that the refrigerated cabinet according to the invention is easy to transport.
  • the unit containing the refrigerant evaporator is arranged above the unit containing the refrigerant compressor.
  • channels for supplying and discharging air are connected to the unit containing the refrigerant evaporator, and the channel used for supplying has an inlet opening in the bottom area of the refrigerator and the channel used for removal has a first outlet opening in the area of the ceiling construction.
  • the device for conveying the air sucks in relatively cold air from the bottom area of the refrigerator and guides the air over the refrigerant evaporator, where the air is cooled.
  • the cold air flows to the outlet opening and from there reaches the outlet opening on the ceiling construction via a channel inside the ceiling construction. From there, the cold air flows into the goods room and cools the goods in it. At least part of the air then returns to the inlet opening.
  • the outlet opening in the area of the ceiling construction can be closed and the duct used for discharge has an additional outlet opening below the first outlet opening.
  • the upper outlet opening is open as long as the goods space is completely filled with goods. If a part of the goods is sold out, so that the lower outlet opening is no longer blocked by goods, the upper outlet opening is closed, so that now all the cold air flows out of the lower outlet opening. This ensures that the entire cold air flow reaches the goods to be cooled as far as possible.
  • the ceiling construction is adjustable in height and optionally assigned to the upper or lower outlet opening.
  • the ceiling structure If the ceiling structure is in the upper position, the cold air passes through the upper outlet opening into a channel in the interior of the ceiling structure and via an outlet opening located therein into the goods space. If a part of the goods has been sold, the ceiling construction is brought into the lower position and the upper outlet opening is closed, so that the cold air flow now passes through the lower outlet opening into the channel in the ceiling construction and via the outlet opening there into the goods room.
  • the ceiling construction can be folded down from its normal position by approximately 90 ° or by approximately 180 ° to the rear.
  • the refrigerated cabinet according to the invention has a merchandise space that is open on the sides and front. It contains only at the rear of the goods room the two units containing the refrigeration unit and the ceiling structure covering the goods room.
  • the merchandise compartment is at least partially clad on the sides with side walls and the merchandise compartment has a cladding on its front in the floor area.
  • the side walls and the cladding are not walls integrated into the refrigerator, but components that are used when required and that do not themselves have a supporting function.
  • a method for operating a refrigerator according to the invention in which the goods are placed in the goods compartment of the refrigerator at a temperature below a maximum permissible storage temperature, is characterized in that less than the heat flowing in from the surroundings is removed from the goods by the refrigeration unit and after a given time span, goods remaining in the goods room are removed from the refrigerator and cooled before reaching the maximum permissible storage temperature.
  • the relatively open goods space of the refrigerated cabinet according to the invention requires powerful cooling.
  • the method according to the invention makes it possible to keep the cooled goods below the maximum permissible storage temperature for a predetermined period of time, for example 4 hours, the cooling capacity supplied by the refrigeration unit delaying the heating of the goods. After the period of time has expired, the goods that have not yet been sold off are cooled again and replaced by fresh goods at a lower temperature. For this purpose, the goods are taken, for example, on a pallet from a refrigerator and in on the pallet the refrigerator set. The pallet with the goods still on it is then returned to the cold store.
  • 1 is essentially constructed from two units 1, 2 arranged one above the other, which contain a refrigeration unit.
  • the two units 1, 2 are detachably connected to one another and can be separated from one another, for example for transport.
  • the refrigeration unit essentially consists of a refrigerant compressor 3, which is accommodated in the lower unit 1.
  • the refrigerant compressor 3 is connected via lines not shown in the figure to a refrigerant evaporator 4 which is arranged in the upper unit 2.
  • the upper unit 2 also contains a device 5 for conveying air.
  • the upper unit 2 is provided with thermal insulation 6, which has connections 7, 8 for the supply and removal of air.
  • Channels 11, 12 are connected to the openings 7, 8 sen, wherein the channel 11, which serves for the supply of air, has an inlet opening 13 in the bottom region of the refrigerator, while the channel 12, which serves for the discharge of air, has an outlet opening 14 in the ceiling region of the refrigerator.
  • the outlet opening 14 is assigned a ceiling construction 15, which has a flow channel in its interior, which is in flow connection with the outlet opening 14.
  • the flow channel in the interior of the ceiling structure 15 has an air outlet opening 16 at its end.
  • the refrigerator can be moved on rollers 17.
  • the merchandise compartment of the refrigerated cabinet which is open both on its front side and on both sides and is therefore very easily accessible to the customer.
  • the goods 17 to be cooled, which is stacked on a pallet 18, are located in the goods room.
  • the all-round open design of the refrigerated cabinet according to the invention makes it possible to move the goods on the pallet from a cold store directly into the refrigerated cabinet. This represents a considerable relief for the operating personnel.
  • air is sucked in via the inlet opening 13, as indicated by arrows 19, passes through the channel 11 to the opening 7, from there through the refrigerant evaporator 4, where it is cooled in heat exchange with evaporating refrigerant, to the opening 8, thence through the channel 12 to the opening 14, from there through the flow channel inside the ceiling structure 15 to the outlet opening 16 and falls as a cold air curtain onto the goods 17. At least some of the cold air falling down then passes through the inlet opening 13 back into the cold air circuit .
  • the refrigeration cabinet according to the invention is ideally suited to display a range of goods in self-service shops on sales days with high sales, which should be visually emphasized and which should be placed in a sales-effective manner, since the refrigeration cabinet is easy to transport and therefore location-independent and, moreover, easily accessible from three sides. Since pallet goods such as e.g. Ice cream, pizza etc. can be adjusted, on the one hand there is the possibility to quickly add or change the range of goods and, in addition, the possibility to operate the refrigerator particularly energy-saving: For refrigerated and frozen goods, the maximum permissible storage temperatures apply, which must not be exceeded . In larger consumer markets, it is customary to store the goods in cold stores, where the temperature is below the maximum permissible storage temperature.
  • the cooling capacity of the refrigerated cabinet according to the invention is set so that the amount of heat flowing into the goods area from the environment is greater than the heat dissipated by the refrigeration unit, the cooling capacity being dimensioned such that the goods located in the goods room are used for a predetermined period of time, for example 4 Hours, safely remains below the maximum permissible temperature value. At the latest after this period, the pallet with the goods is moved back into the cold room and replaced with a fresh pallet from the cold room.
  • the operation of the refrigerated cabinet according to the invention is particularly economical.
  • the channel 12 has an additional outlet opening 20 below the ceiling structure 15.
  • This outlet opening which is preferably preferably closed at first, as soon as part of the goods 17 has been sold and the upper edge of the goods is below the additional outlet opening 20 (dash-dotted line 21) open, so that part of the cooled air flows through the outlet opening 20.
  • FIG. 2 shows two options for folding away the ceiling structure 15 which protrudes towards the front when the refrigerated cabinet according to the invention is shut down: the ceiling structure 15 is either folded down by approximately 90 ° (broken line illustration 22) and then lies essentially parallel to the front wall of the refrigerated cabinet, or it is folded back by approx. 180 ° (dashed illustration 23) and then lies on the top of the refrigerator. In both cases it is achieved that the refrigerated cabinet according to the invention takes up very little space when it is shut down.
  • the refrigerator shown in Figure 3 has side walls 24 on both sides, which are preferably made transparent. At the front of the goods room there is a cladding 25 in the floor area, which is guided on the sides up to the side walls 24.
  • the side walls 24 and the cladding 25 considerably reduce the heat input from the surroundings and improve the cooling in the goods area.
  • the side walls 24 and the Cladding 25 are not integrated into the refrigerator, but are releasably connected to it, for example by plug-in or screw connections, so that the refrigerator can easily be reduced to the format shown in FIG. 2 when not in use.
