Definitions

  • the present invention relates to a refrigerator wherein formation of condensation and frosting on the separator is prevented.
  • the cold air circulation volume situated in front of the rear wall, wherein the evaporator is embedded is separated by a separator from the volume wherein the foodstuffs are stored. Moisture is formed on the separator due to the temperature difference between these two volumes. Moisture is accumulated on the separator so as to be visible from the outside and trickling down, drips into the volume wherein the foodstuffs are stored.
  • insulation elements such sponge, foam, Styrofoam are placed on the separator surface and thereby condensation or frosting resulting from temperature difference is prevented.
  • the aim of the present invention is the realization of a refrigerator comprising a separator whereon formation of condensation and frosting is prevented.
  • the refrigerator realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a compartment wherein the foods and beverages desired to be cooled and/or frozen are placed, a rear wall, an evaporator embedded into the rear wall and providing the cooling of the compartment, a separator disposed in front of the evaporator so as not to contact the rear wall, and a channel by means of which the cold air flow is provided over the evaporator situated between the rear wall and the separator.
  • the separator is disposed between the channel and the compartment which exchange heat with one another.
  • the separator comprises a receptacle that is filled with phase changing material, having high heat conductivity, obtained from binding one or more than one material having eutectic properties.
  • phase changing material having high heat conductivity, obtained from binding one or more than one material having eutectic properties.
  • the receptacle is situated inside the separator.
  • the separator one surface facing the channel, the other surface the compartment, functions as a thermal shield between the compartment and the channel which have a greater difference of temperature. Consequently, formation of condensation and/or frosting on the separator is prevented.
  • the receptacle is situated inside the channel, between the evaporator and the separator.
  • the receptacle insulates the separator from the cold air inside the channel and provides the separator surface temperature to remain close to the temperature of the compartment. Consequently, formation of condensation on the separator is prevented.
  • the receptacle is disposed adjacent to the separator so as to remain between the channel and the separator.
  • the receptacle realizes heat exchange with the compartment both by convection and also by conduction through the separator when the evaporator does not operate in situations like power failure.
  • the refrigerator comprises a container disposed under the separator and a collection tray disposed under the container.
  • the separator surface remains at a lower temperature than the temperature of the compartment while the temperature inside the compartment increases in the course of time in situations like power failure when refrigeration cannot be performed. Therefore, the water vapor droplets in the environment condense on the separator surface depending on the relative humidity inside the compartment. The condensed humidity trickles down towards the container with the effect of gravity as well.
  • the refrigerator comprises a water transfer means that extends between the container and the collection tray.
  • the water in the container inclined towards the water transfer means is transferred to the collection tray on the compressor by the water transfer means.
  • the water collected in the collection tray evaporates due to the heat of the compressor.
  • the phase changing temperature of the phase changing material (M) is between 2° C to 6° C. Phase change is realized without requiring an additional heater since the phase changing temperature of the phase changing material (M) is close to the temperature of the compartment while the evaporator operates.
  • Figure 1 – is the sideways cross sectional view of a refrigerator.
  • the refrigerator (1) comprises a compartment (2) wherein food and beverage items desired to be cooled and/or frozen are placed, a rear wall (3), an evaporator (4) placed in the rear wall (3), which provides the cooling of the compartment (2) by absorbing the thermal energy inside the compartment (2), a separator (5) disposed in front of the evaporator (4) such that a gap remains between the rear wall (3) and the separator (5), and a channel (6) by means of which cold air flow is provided over the evaporator (4) situated between the rear wall (3) and the separator (5).
  • the separator (5) separates the channel (6) and the compartment (2) such that two different temperature zones are formed.
  • the separator (5) comprises a receptacle (7) wherein phase changing material (M) is filled.
  • the separator (5) functions as a heat shield between the channel (6) and the compartment (2) at two different temperatures by means of the receptacle (7).
  • the temperature of the surface of the separator (5) on the side of the compartment (2) remains close to the compartment (2) temperature that is higher than the channel (6) temperature and formation of condensation on the separator (5) surface is prevented.
  • the phase changing material (M) changes phase by absorbing heat from the outside environment and emanating heat to the outside environment.
  • phase changing material (M) provides the interior temperature of the compartment (2) to be preserved for a longer period of time by absorbing the heat inside the compartment (2) since the temperature of the phase changing material (M) falls very slowly during changing of phase.
  • the receptacle (7) is embedded into the separator (5).
  • a more compact structure is obtained by benefiting from the space occupied by the separator (5) inside the refrigerator (1).
  • an effective heat transmission is provided between the receptacle (7) and the separator (5).
  • the receptacle (7) is situated inside the channel (6), between the evaporator (4) and the separator (5).
  • the receptacle (7) at least partially contacts the separator (5) so as to remain between the evaporator (4) and the separator (5).
  • the receptacle (7) realizes heat exchange with the compartment (2) both by convection and also by conduction through the separator (5) during power failure.
  • the refrigerator (1) comprises a container (8) disposed under the separator (5) and a collection tray (9) disposed under the container (8).
  • the separator (5) surface remains at a lower temperature than the temperature of the compartment (2) while the temperature inside the compartment (2) increases in the course of time in situations like power failure when the evaporator (4) does not operate. Therefore, the water droplets condense on the separator (5) surface depending on the relative humidity inside the compartment (2). The condensed water droplets trickle down from the separator (5) surface towards the container (8) with the effect of gravity as well.
  • the refrigerator (1) comprises a water transfer means (10) that extends between the container (8) and the collection tray (9). Water is transferred from the container (8) to the collection tray (9) on the compressor by the water transfer means (10). The water collected in the collection tray (9) evaporates with the heat of the compressor.
  • the phase changing temperature of the phase changing material (M) is between 2° C to 6° C. Phase change is realized without requiring an additional heater since the phase changing temperature of the phase changing material (M) is close to the temperature of the compartment (2) while the evaporator (4) operates.
  • the present invention formation of moisture on the surface of the separator (5) is prevented by lowering the temperature difference between the compartment (2) and the separator (5) surface facing the compartment (2). Furthermore, the temperature inside the compartment (2) is preserved for a longer period of time since the phase changing material (M) absorbs the heat from the environment in situations like power failure when the evaporator (4) cannot cool the interior of the compartment (2).
