Definitions

  • the invention relates to a refrigerated sales cabinet with a lower, chest-shaped goods room, which is open at the top, and with an upper, showcase-shaped goods room, which is arranged above the lower goods room, and with supply air ducts through which soft cold air is directed into the two goods rooms. and with return air ducts through which air is extracted from the goods rooms.
  • Such refrigerated display cabinets are generally used for the storage and presentation of goods below the ambient temperature in retail stores.
  • the two-part type discussed here is most commonly used for frozen foods. Its lower goods area essentially corresponds to an upright freezer and is supplied with cold air at the rear edge facing away from the customer via a supply air duct. At its front edge, air is drawn off via a return air duct, fed to an evaporator for cooling, and then fed back into the supply air duct.
  • the upper goods area is generally closed with doors on its front facing the customer. It is supplied via a cooling air circuit similar to that of the lower goods area. However, the return air is drawn off in its lower area.
  • a separate evaporator is usually located behind or below the upper goods area.
  • FIG. 705 875 An example of a generic refrigerated display cabinet is known from FR-A-2077310.
  • the US-2 705 875 also shows a refrigerator with two stacked goods rooms, both of which are chest-shaped and open at the top and are supplied with cooling air via a common supply air duct .
  • the invention is therefore based on the object of improving the refrigerated display cabinet of the type mentioned in such a way that its economy in terms of acquisition and operation is increased.
  • the available merchandise volume should be increased as much as possible.
  • a first, common supply air duct starts from an evaporator and branches into a second and a third supply air duct, the second supply air duct leads into the lower goods area and the third supply air duct leads into the upper goods area, and a first flow brake at the entrance to the second supply air duct is arranged .
  • the design of the invention enables the connection of the two cooling air circuits for the two goods rooms, so that it is possible to work with a common evaporator and with a common blower system. This combination increases the profitability of the refrigerated display cabinet, in particular by reducing material, assembly and maintenance costs.
  • Another advantage of using a common evaporator for both warehouses is the reduced cooling requirement. This results from the fact that only one evaporator has to be defrosted. As a result, the defrosting heat to be removed after the defrosting process is reduced by half compared to the previously known refrigerated display cabinet with two evaporators.
  • cooling air is relatively unproblematic in closed rooms to be cooled, such as can be found in household refrigerated furniture or also in the display case-shaped goods room of the refrigerated display cabinet according to the invention.
  • a flow entering with turbulence is sufficient. For this reason, in the case of such closed goods rooms, a supply air flow can simply be divided and directed into the corresponding sub-rooms.
  • the lower, chest-shaped goods area of the refrigerated display cabinet according to the invention also represents such an open space to be cooled. There is no solid insulation at the top, although there can be a temperature difference of more than 40 K along the entire upper chest opening (ambient temperature of climate class 3 according to DIN 8954: 25 ° C, relative humidity: 60%, maximum temperature in a freezer: -18 ° C).
  • the supply air for both goods rooms is brought from a common evaporator and then divided into two partial flows, one for the upper one and one for the lower one.
  • the problems in the branching of a laminar partial flow for the lower goods area, which were previously considered insurmountable, can be overcome by the first flow brake according to the invention .
  • the first flow brake is preferably formed by a substantially horizontal and essentially vertical perforated plate, which are arranged at the entrance of the second supply air duct. It generally covers the entire cross section of the second supply air duct. As a rule, the horizontal cross section of the duct is not sufficient to branch off a sufficient amount of supply air at a sufficiently low speed for the lower goods area. The vertical alignment of a part of the flow brake creates additional space through which the supply air can flow (slowly).
  • a second flow brake is advantageously arranged within the second supply air duct. This is connected in series with the first. It can also be provided without the first, but the interaction of the two devices is favorable.
  • the (only) evaporator of the refrigerated display cabinet can, for example, be arranged behind one of the goods rooms. However, it is particularly advantageous if, according to a development of the invention, the evaporator is arranged below the lower goods area.
  • Both return air flows (from the upper and from the lower goods area) are fed to this evaporator, which of course can also consist of several structurally separate sections.
  • the supply air for both warehouses is drawn in via this evaporator.
  • the blower system is preferably also arranged on the underside of the refrigerated display case.
  • the location of the single evaporator below the lower merchandise compartment enables a significant expansion of the upper merchandise compartment to the rear or below compared to a two-evaporator system, without additional space being converted or even taking up more floor space. This means that a larger volume is available for the presentation and storage of goods. There is no additional need for cooling, since the losses due to convection (via openings) and heat conduction (via edge areas of the goods rooms) remain unchanged.
  • a problem with the refrigerated display cabinet according to the invention arises from the relatively large distance between the extraction point for return air in the front area of the upper goods area and the evaporator on the underside of the lower goods area. In a test device it turned out that the cooling of the upper goods area did not work satisfactorily under all circumstances.
  • fans for sucking in the return air are therefore arranged within the return air duct or ducts for the upper goods area.
  • fans are also installed in the return air ducts, that is to say in front of the evaporator. (If there is only one return air duct, a blower is of course sufficient for this purpose.) This ensures that the upper goods area is adequately supplied with cold even under unfavorable conditions.
  • the return air ducts preferably lead into an intermediate space between the bottom plate of the lower merchandise compartment and the top of the evaporator and merge there, if they are provided in the majority.
  • the return air ducts can only occupy part (e.g. two fifths) of the length of the furniture on the level below the lower goods area to allow the supply air duct to be led past. Nevertheless, the return air must be distributed as evenly as possible over the air inlet of the evaporator, which usually extends over most of the entire length of the piece of furniture.
  • a device for distributing the return air over the entire length of the furniture is provided below the lower goods area.
  • This advantageously consists of vertical perforated plates, which are arranged at an angle to the transverse axis of the furniture.
  • this oblique arrangement increases the free passage area for the air flow compared to a horizontal arrangement (perpendicular to the direction of flow).
  • the transverse axis in the sense of this formulation is perpendicular to the rear wall of the refrigerated display cabinet.
  • the return air ducts for the upper goods area in the air inlet area of the evaporator combine with a return air channel for the lower goods area. Then the return air from both warehouses is fed together to the outer surfaces of the evaporator.
  • a mixing fin is arranged in the air inlet area of the evaporator between the return air ducts for the upper and the lower goods area. This causes the return air flowing in from the rear to be deflected towards the air inlet of the evaporator and thus a parallel guidance of the two return air flows (from the upper and from the lower goods area) during mixing. This is the only way to ensure an even flow to the evaporator.
  • the mixing fin advantageously consists of a plate which is arranged obliquely to the horizontal and extends essentially over the entire length of the piece of furniture.
  • Unperforated sheet metal is usually used, but the type of material is not important.
  • supply and, above all, return air ducts can be routed past one another outside the furniture body via hoses or similar devices.
  • hoses or similar devices since there is not always enough space for this and such a construction also has a high susceptibility to faults, it is advantageous if, according to a partial aspect of the invention, two return air ducts for the upper goods space and supply air ducts within a functional space behind the lower goods space on the side facing away from the customer Refrigerated display cabinets are arranged.
  • the supply air duct or ducts can lead cooled air from the bottom of the furniture to the upper edge of the lower goods area.
  • the return air duct or ducts return air from the upper goods area down.
  • several return air ducts are provided, but one return air duct, for example arranged in the middle of the longitudinal extent of the furniture, can also be used.
  • the above-mentioned channels are all located in a functional space, which is generally limited to the front (towards the customer) by the rear wall of the lower goods area and to the rear by the rear wall of the furniture and extends over the entire length of the furniture.
  • the upper goods area Via the second supply air duct, an extension of the first supply air duct, along the back of the upper goods area, the upper goods area can also be supplied at its upper edge. In this way, supply air can be supplied from below the lower goods room to both the lower and the upper goods room.
  • return air which is taken from the upper goods area in its lower front area, can be returned downwards via the return air ducts arranged in the functional area.
  • the return air is routed for the lower goods area as is known.
  • the first supply air duct within the functional space has a full section arranged next to the return air ducts for the upper goods space, which extends essentially over the entire depth of the functional space, and auxiliary sections of smaller depth arranged between each return air duct and the lower goods space.
  • the auxiliary sections are next to it and are bounded at the rear by a return air duct and at the front by the rear wall of the lower goods area. They ensure that cooling air flows along the entire length of the furniture into the second supply air duct to supply the lower goods area.
  • a guide device arranged in the auxiliary sections for guiding the air flow in the vertical direction is therefore provided. It preferably consists of walls arranged vertically and perpendicular to the rear wall of the furniture, for example realized by perforated plates.
  • this guide device effects a uniform distribution of the supply air for the lower goods area over the entire length of the supply air duct; secondly, the fact that the supply air flowing into the lower goods space via the auxiliary sections has practically no flow component in the longitudinal direction of the furniture, so that the homogeneity of the cooling air flow is also ensured in the front areas of the lower goods space.
  • the refrigerated display cabinet selected as an exemplary embodiment of the invention is first explained using the cross-sectional drawings of FIGS. 1 and 2. (The intersection lines of FIG. 1 (A - B) and FIG. 2 (C - D) are shown in FIG. 3b.)
  • the refrigerated display case has a lower, chest-shaped merchandise space 1, which extends towards the front, towards the customer side, through a front wall 3 mounted glass pane 4 and is limited by a rear wall 5 to the rear.
  • An upper, showcase-shaped goods space 2 is arranged above it, which is equipped with doors 6, preferably made of transparent material, on its front side. It is also closed off at the rear by a rear wall 7.
  • a functional space 9 extends between the rear wall 5 of the lower goods space 1 and the rear wall 8 of the furniture over the entire length of the furniture.
  • both return air ducts 10 and full and auxiliary sections 20 and 21 of a first supply air duct are located within this functional space 9.
  • FIG. 2 shows that the full section 20 extends over the entire depth of the functional space, that is to say from the rear wall 5 of the lower goods space 1 to the furniture rear wall 8.
  • the auxiliary sections 21 have a smaller depth (the left of the two can be seen in FIG. 1). Behind the auxiliary section 21 there is a return air duct 10 within the functional space 9, which essentially extends over the height of the lower goods space 1.
  • FIG. 3 shows the arrangement of the various channels along the longitudinal coordinate of the furniture.
  • the sectional plane changes approximately in the middle of the piece of furniture:
  • FIG. 3a shows a section along line E - G of FIGS. 1 and 2
  • the sectional plane of FIG. 3b is slightly offset to the rear in the lower part and runs along the axis E - F
  • the refrigerated display cabinet is constructed symmetrically to an axis that runs along the dividing line between FIGS. 3a and 3b, it is easy to extrapolate to the other half of the cabinet. In both cases, the viewing direction is from the back of the furniture towards the customer.
  • FIGS. 3a and 3b make it clear that return air ducts 10 and auxiliary sections 21 of the first supply air duct take up a total of about 2/5 of the entire length of the functional space.
  • An auxiliary section 21 and return air duct 10 are each arranged next to a side wall 30.
  • the full section 20 of the first supply air duct lies in between.
  • the first supply air duct is continued upwards by a third supply air duct 22, which extends further up (behind the upper goods area 2) to the full length of the furniture.
  • Return air from the lower goods area is drawn in in a conventional manner via an opening 15 and a channel 18, both of which run over the entire length of the upper edge of the front wall 3. As can be seen in FIGS. 1 and 2, it then flows to the front of an evaporator 31 in order to be cooled on its outer surfaces. The evaporator is located below the lower goods area.
  • return air is conducted to the rear via a channel 11 running under the goods room in the horizontal direction. This crosses the functional space 9 in two lateral sections, which open into the return air ducts 10. From there, the return air is conducted through a return air fan 32 into a continuation section 12 of the return air ducts 10 located below the lower goods room 1 above the evaporator 31 into the front area 16 of the furniture.
  • the return air fans 32 serve as fans to overcome the flow resistance in the duct sections 10, 11 and 12.
  • FIG. 5 shows the region 12 above the evaporator 31.
  • Perforated plates 33 which are arranged vertically at an angle of 20 ° to 70 °, preferably about 45 ° to the plane of the furniture rear wall, serve as a device for distribution. They partially divert the return air towards the center, as indicated by the arrows in the left part of FIG. 5.
  • the plates 33 consist of commercially available perforated sheet metal, but other materials can be used just as well.
  • the plates 33 can, for example, also be provided with a continuous horizontal gap.
  • a mixing fin 17 preferably made of non-perforated sheet metal, supports a smooth mixing with the return air flow from the lower goods area 1, so that the front surface of the evaporator 31 is flowed uniformly and laminarly (see FIGS. 1 and 2).
  • the air cooled in the evaporator 31 enters the suction space 34, which extends over the entire length of the furniture. It is sucked back upwards by two supply air fans 23 via this suction space 34 and initially only flows into the full section 20 of the supply air duct, which lies in the middle of the functional space 9. Above the horizontal section 12 of the return air duct, the supply air can also flow laterally into the auxiliary sections 21 (FIG. 3a). There it is redirected in a vertical direction by a guide device. For each auxiliary section 21, this consists of two perforated plates 27a, 27b which run over the entire depth of the auxiliary section 21, the inner plate 27a being shorter than the plate 27b lying further out. In the vertical direction, the plates 27a, 27b extend up to approximately 10 mm to the horizontal perforated plate 25a, which is arranged at the entrance of the second supply air duct 24. To the lower edge of a branch duct 24.
  • the second supply air duct 24 occupies part of the functional space 9 between the line 25a shown in broken lines in FIGS. 3a and 3b and a honeycomb 26, both above the full section 20 and the auxiliary sections 21 of the first supply air duct. It is used to attack part of the supply air for the lower goods area. Its structure is shown in cross-section in the detailed drawing of Figure 4.
  • perforated plate 25a or 25b Through the openings of a horizontally and a vertically arranged perforated plate 25a or 25b (first flow brake), part of the supply air flows from the full or from the auxiliary sections 20 or 21 of the supply air duct into the branch duct 24. There it meets another, obliquely arranged perforated plate 25 c (second flow brake), which further reduces the speed of the flow and gives it a laminar character. All three perforated plates 25a, 25b, 25c act as a flow brake for the supply air for the lower goods area 1.
  • the continuation of the auxiliary section 21 is closed at the top by a horizontal plate 27c (see FIG. 4). This prevents air from flowing into the second supply air duct 24 from top to bottom via the first flow brake (25a, 25b).
  • the laminar supply air flow is finally deflected forward at the upper end of the branch duct 24 and fed to the lower merchandise space in its full length by a honeycomb 26.
  • the part of the supply air that is not tapped flows through the full section 20 between the horizontal ducts 11 for the return air from the upper goods area 2 into the upper section 22 of the supply air duct. Due to the hydraulic pressure which arises and the low kinetic energy of the supply air flow, the air is distributed over the entire extent of the upper section 22 and is pressed into the upper goods space 2 at its upper end.
  • the number of fans 23, 32 of the blower system is four in the special exemplary embodiment. Depending on the length of the furniture, a different number of supply and return air fans is required.
  • the refrigerated display case has, for example, a length of 2.50 m in the embodiment shown in the drawings.
  • refrigerated display cabinets of any length according to the invention are conceivable.
  • an additional component which corresponds to the right half of the 2.50 m long piece of furniture according to FIGS. 3 and 5, can be added on the right side.
  • the sales furniture according to the invention results in an upper merchandise compartment 2 enlarged to the rear or upwards compared to the previous construction. Behind the upper merchandise compartment 2 there is neither a voluminous evaporator nor a blower, but only the upper section 22 of the Supply air duct, the expansion of which is relatively small. A marginal shortening of the lower goods area 1 has to be accepted.
