Definitions

  • This invention relates to freezers.
  • a freezer characterised in that it incorporates a cold store having an eutectic temperature less than a desired operating temperature of the freezer.
  • a freezer as set forth in the immediately preceding paragraph wherein the cold store has an evaporator coil of a refrigeration system of the freezer contained therein, thereby substantially limiting the lowest operating temperature of the evaporator to the temperature of the oold store.
  • the cold store comprises a brine solution, having an appropriate eutectic temperature, which gives up heat energy and thus undergoes a phase change, during the operation of the compressor, and which slowly absorbs heat energy from within the freezer and thus undergoes a reverse phase change, when the compressor is not in operation.
  • an upright freezer having an outer housing 1 and a door 2 contains a number of shelves, labelled 3 to 6 respectively, upon which items of frozen food, such as that shown at 7, are stored.
  • Each shelf comprises a casing 8, which is filled with a brine solution 10 having an eutectic temperature a few degrees lower than the desired operating temperature of the freezer, the brine solution 10 also having an evaporator coil 9 immersed therein.
  • each shelf is connected in series and form part of a refrigeration system of known construction including a compressor (not shown in the diagram), which is situated to the rear of the food storage compartment of the freezer.
  • the compressor is run (to the extent necessary) on a cheap rate of electricity, such as "Economy 7," so that, due to the evaporator coils being immersed within the brine solution, heat energy is transferred from the brine solution, which thus undergoes a phase change, into the evaporator coils, thus providing a cold store within each shelf.
  • a cheap rate of electricity such as "Economy 7”
  • the brine solution then slowly absorbs heat energy from within the freezer, so that the solution undergoes a reverse phase change over a substantial length of time, thus maintaining a substantially constant desired operating temperature within the freezer.
  • the brine solution may be substantially greater in volume in one phase than the other, so that, to accommodate for the volume increase, it may be necessary to provide an air gap between the surface of the solution within the casing 8 and the upper surface of the casing.
  • Such a gap may also prove necessary to provide means for ensuring good thermal contact between the upper surface of the casing, upon which the food items are placed, and the solution.
  • These means may comprise, for example, protuberances extending down from the upper surface of the casing into the solution.
  • this arrangement in accordance with the present invention should provide a substantial energy saving, as the compressor is only run during a period of cheap rate of electricity, and thus this substantially lowers the running cost of a freezer of this kind, as well as providing improved refrigeration efficiency due to lower night-time ambient temperatures, which reduce the temperature difference between the evaporator and condensor of the refrigeration system.
  • the present invention could be incorporated within a chest freezer, as well as an upright freezer as in the preferred embodiment.
  • a chest freezer due to the distribution of food in a chest freezer, it may be necessary to use a combination of both cold store sachets and shelves to ensure that a substantially constant desired temperature is maintained within the whole volume of the freezer.
