Definitions

  • the present invention relates to a refrigeration apparatus, particularly for use in environments where electrical power may be interrupted.
  • the invention is primarily directed towards environments where the interruption to the power supply is out of the control of the end user, this invention may also be used to reduce the power cycle of conventional freezers in that there is no requirement for the power supply to such conventional freezers to be continuous. This may be a consumer desired requirement for "green” reasons or may be as a result of the use of these freezers at public events.
  • the present invention seeks to address the foregoing problem by providing a refrigeration apparatus for beverages comprised of a walled enclosure with an access means, further including a refrigerating means for cooling the enclosure, and a secondary cooling means.
  • the secondary cooling means is an ice based element or compartment.
  • This may contain a eutectic material that will stay in a solid "ice” state for as long as possible.
  • the eutectic is formulated to freeze at a temperature above zero Celsius degrees.
  • the eutectic material would have a melting temperature approximately equal to the optimal serving temperature of a beverage, e.g. ⁇ °C.
  • a eutectic material suitable for use with the invention was supplied by Phase Change Material Products Limited (www.pcmproducts . net, Yaxley, Cambridgeshire, UK) . To achieve the invention a blend of 70% E7 and 30% A4 eutectic was used.
  • eutectic materials have been known but are usually associated with freezer environments where the melting temperature is below 0°C, often as low as -10 0 C.
  • the refrigerator enclosure is in a "chest" style with a slidable door or lid providing access.
  • bottles or cans are preferably located into separate compartments (pockets) .
  • the compartment walls are formed of a material that enables heat to transfer away from the bottle or can toward ice or another "cold mass” formed or located between the compartments. This is in contrast to most bottle/can compartmental enclosures that usually have insulating properties in order to inhibit the flow of heat to the bottle or can and to maintain the temperature within the refrigerator.
  • the secondary cooling means is an ice mass formed by an electrically powered refrigeration circuit.
  • the ice mass is formed by submerging a cooling pipe lattice or coil into water, such that, as coolant passes through the pipe, heat is drawn from the water and it eventually freezes.
  • the pipes are arranged between the bottle compartments.
  • the refrigeration apparatus is a standing refrigerator with a door providing the access means to the interior of the enclosure.
  • a eutectic material (freezing above 0°C) is located in, at or adjacent a wall or shelf of the refrigerator. Most ideally, a surface of the eutectic material is in contact with a beverage container.
  • the door is preferably transparent such that contents of the fridge can be viewed without opening the door.
  • Figure 1 shows a plan perspective view of a refrigeration apparatus according to a preferred embodiment of the invention
  • Figure 2 shows a detailed view of the embodiment from Figure 1
  • Figure 3 shows a front perspective view of a refrigeration apparatus according to a further embodiment of the invention, MODE(S) FOR CARRYING OUT THE INVENTION
  • Figure 1 illustrates a preferred embodiment where the refrigeration apparatus is in the form of a chest refrigerator with top access via a sliding door 19, sliding on rails 19a.
  • This embodiment utilises a secondary cooling means and an additional feature of plural bottle pockets 20 each capable of receiving a beverage bottle B (or aluminium can) .
  • each bottle pocket 20 are preferably formed from a suitable material such that heat from a bottle (i.e. at ambient temperature) is transferred away to improve the cooling effect provided by the primary refrigeration means (and/or secondary cooling means) . At the least, walls 21 should not substantially hinder heat transfer.
  • pockets 20 were constructed from a conventional PVC downpipe which was found to be sufficient for transferring heat away from a bottle B.
  • the walls 21 are rigid, but a variety of diameters/depths can be provided to accommodate different package sizes.
  • FIG 2 illustrates further detail of the preferred embodiment, specifically providing a view below a cover 22 seen in Figure 1. It is intended that pipework 23 is submerged in a liquid medium (e.g. water) and carries a refrigerant.
  • the pipework 23 would generally be considered the primary cooling or refrigerating means according to the invention.
  • ice will form around pipes 23 while submerged in the water bath to eventually turn the entire body of water to solid ice, thereby creating a cold mass in between the pockets 20.
  • the iced pipework 23 and cold water (although preferably it will be a solid ice block) surrounding pockets 20 will act as an ice bank and therefore maintain the bottles B at a sufficiently low temperature to keep a beverage refrigerated for many hours (preferably twelve hours or more) .
  • the ice mass is effectively the secondary cooling means according to the invention.
  • the form of pipework arranged between the pockets directs heat removal as close as possible to the bottles/cans within the pockets 20.
  • the water bath within which pipework 23 is submerged could be a eutectic liquid/material as will hereinafter be described.
  • refrigeration apparatus 10 is in the form of an upstanding refrigerator accessible via a door 11 mounted for swinging movement on a hinge 12.
  • door 11 includes a magnetic seal 13 that holds door 11 in a closed position so that the overall enclosure 14 is isolated from ambient conditions.
  • a series of racks or rails 15 are provided to hold a beverage bottle B (or aluminium can) in a convenient manner for easy accessibility by a user.
  • Rails 15 are, in the illustrated embodiment, on a slight incline such that bottles B naturally migrate toward the front of the enclosure 14 allowing for replacement bottles (or cans) to be placed at the rear of the enclosure providing for easy access to the bottles (or cans) at the front of the enclosure which will consequently have been within the refrigerator for the longest period of cooling.
  • the refrigeration apparatus 10 is of conventional design in that the walls 16 of enclosure 14 are insulated and primary refrigeration is provided by a condenser/compressor circuit with a motor powered by a mains supply.
  • this secondary cooling means utilises a series of compartments 17 for receiving a block of material such that it forms an "ice bank”.
  • the secondary cooling means may be a plastic skin containing a eutectic material with a melting point higher than water.
  • the inclusion of the secondary cooling means enables the enclosure 14 to remain at a sufficiently low temperature of around 5 degrees even if the conventional refrigeration circuit is turned off (through power failure)
  • the eutectic material can be chosen/developed with a melting point of, e.g. 7 0 C. In other words it will phase change from a liquid to a solid state at about 7°C. In practice, materials usually begin to "freeze" at a few degrees below the melting temperature. Therefore, in a conventional refrigerator environment of approximately 4°C, the eutectic material will be guaranteed to remain in a solid state. Ideally, the eutectic material melting temperature is approximately equivalent to the optimum serving temperature for the beverage, e.g. 6 or 7°C.
  • a eutectic material with a melting point of 7°C utilised with the present invention is expected to remain in a solid state for many hours, effectively providing a cooling function to a temperature just above the normal operating temperature (4°C) of the refrigerator when the power supply is interrupted.
  • the eutectic material acts so as to both maintain the temperature of the bottles/cans already within the refrigerator and also reduces the temperature of newly added bottles/cans as product is removed.
  • the secondary cooling means of the invention i.e. eutectic material
  • the secondary cooling means of the invention may be in direct contact with one or more bottles B within the enclosure.
  • a cooling mass is incorporated or built into the rack/rail arrangement of the Figure 3 embodiment. It is generally found that the invention is more effective when the secondary cooling means
  • the refrigerator enclosure may include shelves formed of or with a eutectic material. In this way a bottle or can of beverage sits on the eutectic shelf and its base is in constant contact. Furthermore, pockets 20 of the type described in relation to the Figure 1 embodiment could be incorporated into the Figure 3 embodiment .
  • the above data is based on the use of water/ice as the cooling mass which typically remains in a frozen state at 0°C.
