Definitions

  • the invention relates to a device for significantly improving the performance of furniture, display cases, counters, bins, stalls or displays intended for presentation and sale of foodstuffs kept at a temperature below room temperature.
  • refrigerated or frozen furniture is widely used in food distribution stores, in pharmacies selling pharmaceutical products or more generally, each time that it is necessary to keep products at a temperature below the ambient temperature.
  • the furniture, display cases, counters, bins, refrigerated or frozen stalls or displays will be designated by the generic designation of refrigerated display cabinets.
  • This ice formation has the effect of constituting gradually an insulating sheath around the evaporator and its fins, so that on the one hand, the exchange coefficient between this element and the circulating air decreases and on the other hand the pressure drops increase, which has the effect of significantly reducing the refrigerated air flow.
  • GB-A-2 278 668 describes a refrigeration cabinet having the Characteristics of the preamble of claim 1.
  • the invention provides ways to take advantage of the positive effects of the appearance of frost on the surface of the evaporator and cancel the negative effects of this phenomenon.
  • the invention proposes to produce refrigerated cabinets of sale which overcome all the drawbacks exposed above.
  • Another objective of the invention is to offer refrigerated display cabinets for sale having better energy efficiency, i.e. consuming a quantity less energy for a given level of performance.
  • a complementary objective of the invention is to allow furniture to be produced sales refrigerators whose cost price is significantly lowered, a result which is obtained by optimizing elements such as the evaporator and the fans which can operate regularly up to 100% of the time and therefore have a size smaller than those currently used in furniture that would target performances of the same level as those of refrigerated display cabinets according to the invention.
  • Another additional objective of the invention is to provide furniture refrigerated sales with economical and effective means to remove any proliferation of germs or germs on the evaporator and of its immediate environment and, therefore, to avoid any risk of contamination foodstuffs or products kept inside refrigerated display cabinets.
  • the object of the present invention is to produce a refrigerating cabinet with circulation pulsed air whose defrosting of the evaporator by microwave does not cause a air curtain heating or significant energy consumption.
  • the evacuation means consist of the means traffic. Indeed, the pulsed air flow takes away part of the water (liquid) present on the evaporator outside the enclosure by transporting it into the air.
  • the evacuation means comprise at minus one orifice formed in the lower wall of the enclosure. Water will flow along evaporator fins and will fall by gravity. It will then be collected in a metal container then evacuated outside the enclosure.
  • the passage of water to through the lower wall of the enclosure subjected to radiation will be preferably through one or more orifices, a grid or a perforated sheet of which the opening sections will be chosen, depending on the nominal frequency of the generator, so that they constitute a wave trap. This passage will be accelerated by slopes converging towards the discharge opening (s), slopes conferred by construction at said bottom wall.
  • the evaporator or at least its active part, will be contained in an enclosure impervious to microwaves so that they will be reflected on the walls of said pregnant and give up their energy in priority to the ice or frost it will melt.
  • a waveguide preferably provided with deflectors, will direct the waves towards the evaporator fins.
  • a wave brewer intended to orient or distribute the waves in preferred directions or zones.
  • at least two of the walls will be produced in the form of grids or perforated sheets with openings of sufficient size to allow the transverse air flow to pass through the enclosure and insufficient to allow escape the microwave radiation outside the enclosure.
  • partitions solid or partially openwork removable metal, said partitions being automatically retracted or folded down during short periods of operation of the microwave generator (s).
  • waveguides should be made in such a way that the waves are exclusively or, failing that, preferably directed towards the evaporator, or even towards the area of said evaporator more particularly subject to frost setting phenomena or in ice, ie the area through which the pulsed air comes into contact with this element.
  • These surface waveguides will be coupled to the microwave generator and made of a dielectric material of which the dielectric constant will be close to that of frost and whose thermal conductivity will be close to that of copper; these two characteristics are interesting: the first provides good wave propagation between the surface waveguides and the layer of frost and the second prevents the surface waveguides from act as insulators which would decrease the exchange efficiency between the evaporator and the air flow. To obtain these two characteristics simultaneously a contradictory between them, we will choose to make the surface waveguides in materials belonging to the family of polymers or resins doped by inclusion of non-magnetic metallic particles.
  • the spacing between the fins constituting the evaporator exchange surface in such a way that this spacing allows a optimum passage of microwaves between two neighboring fins, i.e. a spacing greater than 5 mm and in such a way that this spacing makes it possible to obtain a large exchange surface between the evaporator and the air, i.e. a spacing less than 10 mm.
  • the evaporators with which the refrigerated display cabinets according to the invention will therefore be provided with fins of which the spacing will be between 5 and 10 millimeters.
  • the evaporator with a certain number of fins elongated, substantially exceeding the alignment of the ends of the standard fins.
  • We in this case will choose the spacing between two elongated fins so that the said spacing allows good microwave penetration between an elongated fin and its close neighbors in the same category (more than 5 mm), while we will choose the spacing of the standard fins between them in such a way that says it spacing (chosen as less than 5 mm) is little or not compatible with the microwave penetration in the intervals between these standard fins.
  • the furniture according to the invention comprises, as the furniture currently offered, a bodywork 1, one of the cooling means which can be in the form of one or a plurality of evaporators 2, traversed by a flow of air pulsed by at least one fan 3.
  • This air after passing over the evaporator 2 in contact with which it undergoes significant cooling is channeled between the walls of the bodywork 1 and is then sent to the open front of the cabinet at level of which it forms an air curtain 5. It is through this air curtain 5 that the products can be placed inside or extracted from the furniture, supported as they by shelves 6.
  • the furniture according to the invention may belong indifferently to the category known as "housed group” in which case they will include complementary components like a compressor and a condenser, or at the so-called “remote group” category in which case the other elements of the refrigerant group will be located outside the body 1, the evaporator 2 being connected to said group by pipes allowing the circulation of the coolant.
  • the refrigerated display cabinets according to the invention will be equipped with at least a means for emitting energy in the form of microwaves 10. They are characterized in that that their evaporator 2 is placed in a zone delimited by an enclosure 12 in which microwave energy emission means 10 emit microwaves.
  • the enclosure is constructed in such a way that it is microwave-tight.
  • these energy emission means in the form of microwaves will consist of at least one microwave generator, commonly called Magnetron.
  • This Magnetron 10 will emit its energy via an antenna in a waveguide 11.
  • Said waveguide will open into an enclosure 12 containing all or part of the evaporator 2.
  • a wave stirrer 13 and / or deflectors of waves 14 which will supplement the means of emission and distribution of energy microwave inside enclosure 12.
  • these surface waveguides will be thin.
  • These surface waveguides 4 will be formed by a layer or by a plurality of layers of dielectric material, said dielectric material having a constant dielectric close to that of frost and a thermal conductivity close to that of copper, it will preferably be chosen from the family of polymer materials or resins doped by inclusion of non-ferromagnetic metal particles. So the surface waveguides will cause little or no disruption to heat exchange and will allow an optimized diffusion of the waves towards the frost whose formation will be fought in a particularly fast and effective way and whose thickness could be maintained at an optimal value.
  • the enclosure 12 is both waterproof in the microwave and not airtight.
  • the enclosure 12 will be constructed in such a way that microwave energy is confined within its interior volume which it will have no way to escape while the air flow circulated by the fans 3 will be able to cross it right through by undergoing a small pressure drop.
  • This double characteristic will be obtained by providing said enclosure 12 with at least two opposite metal walls 15, 16 pierced with small diameter holes (some millimeters in diameter if microwave generators are used at a frequency of 2450 MHz), the holes being arranged in an extremely close manner, if although the air passage section will be at least 50% of the total area.
  • the enclosure 12 will include in its lower part at least one orifice 19 allowing the flow by gravity of the water outside the enclosure.
  • This orifice 19 will be fitted with a wave trap or be of sufficiently small size to prevent any passage of radiation towards the outside of the enclosure 12.
  • the two opposite walls 15, 16 allowing the passage of air will be removable walls, produced in the form of sliding hatches or shutters, using full or partially metal sheets openwork.
  • These opening and closing devices will be motorized and controlled by a automated device so that they are in the closed position during the phases emission of microwave energy and in the open position the rest of the time. This provision will allow completely free passage of air through the enclosure 12 during periods of non-operation of the microwave energy emission means 10, the said walls 15, 16 being obviously closed or folded down during periods of functioning of the means 10.
  • the air circuit inside a refrigerated sales unit is produced in such a way that the air is set in motion by at least a fan 3, passes through a perforated or removable wall 16 of the enclosure 12, passes over at least one evaporator 2 passes through a second perforated or removable wall 15 of the enclosure 12 and is then guided inside the body 1 to a face constantly or occasionally open that it travels in the form of an air curtain 5 to return to the fan (s) 3.
  • This refrigerated air circuit in contact with the evaporator 2 keeps the food contained on the shelves 6 at a constant refrigerated temperature.
  • the energy emission means 10 microwave it will be advantageous to control their operation either to a measurement of the air flow after passing through the evaporator 2, or to a measurement temperature, either by measuring the humidity in the air flow, or by a gel placed at the level of evaporator 2, or again to any combination of these information.
  • we will endeavor to dose and direct the radiation microwave by actuating the means 10 for transmitting microwave energy which will be coupled with means of orientation or distribution of energy microwave in enclosure 12, the so-called means of orientation or distribution of the microwave energy in the enclosure 12 being constituted by at least one guide 11 and / or a wave stirrer 13 and / or deflectors 14 and / or guides of surface waves 4 or by any combination between all or part of these elements.
  • the means 10 for emitting microwave radiation will be actuated cyclically or continuously so that they have the effect of maintaining, on at minus part of the external surface of the evaporator 2, a layer of frost low and optimal thickness. To obtain maximum performance, the thickness of this layer of frost will be between a zero thickness and a thickness of 1 mm.
  • FIG. 3 shows an arrangement intended to improve the thermal efficiency of furniture according to the invention. This is to cause a maximum deposit of frost on specific fins 18, longer than the fins 17 of the evaporator 2. This protuberance will be carried out on the front face of the evaporator 2, ie towards the wall 16 by which the air flow pushed by the fan 3 enters the enclosure 12.
  • the extensions of the fins 18 being the first cold surfaces encountered by the flow of air, we understand that the frost will form preferentially on the so-called extensions.
  • the fins 18 being more spaced than the fins 17 the phenomena obstruction will be delayed; in addition, the microwave energy will preferably be directed towards the zone in which the said fins 18 protrude relative to the ends of ordinary fins 17.

  • the area of projection of the fins 18 relative to to the fins 17 and the preferential emission zone of the microwave radiation will be oriented towards the wall 16 of the enclosure 12 by which the flow of air being stirred enters said enclosure 12.
  • FIG. 4 shows the operating diagram of a refrigeration cabinet sale equipped with an evaporator defrosting device included in the prior art.
  • the cooling capacity is represented on the vertical axis, while the horizontal axis represents time.
  • the operation is based on the repetition of identical cycles. For each of these cycles, initially, the cooling capacity increases, due to the appearance of a thin film of frost on the evaporator fins.
  • the power increases from initial level 21 to maximum level 20.
  • training of frost or ice results in the formation of an insulating layer and the start of reduction of the air passage section between the fins which compensate and cancel the beneficial effects of the initial frost formation, so that the cooling capacity falls back to the initial level 21.
  • FIG. 5 shows, in the same presentation as Figure 4, a diagram of operation of a refrigerated display cabinet according to the invention.
  • the start of cycle is identical, that is to say that a thin layer of frost is allowed to form in surface of the evaporator.
