Definitions

• the present invention relates to a refrigerator and / or freezer with at least one body and at least one arranged in the body cooled interior, the device having at least one refrigerant circuit, which serves to cool the interior, wherein the refrigerant circuit has at least one condenser.
• the condensation of the refrigerant takes place, during which heat is released.
• the present invention has the object of developing a refrigerator or freezer of the type mentioned in such a way that the Vertexerab Marvel is used efficiently.
• At least one heat pipe is provided, which is in direct or indirect thermal contact with the condenser and which is arranged such that it forms at least part of the frame heating of the device and / or in thermal contact with the outer skin of the device stands.
• the present invention thus uses the heat generated in the region of the condenser and indeed for operating a frame heating and / or for heating at least part of the outer jacket of the device according to the invention.
• a frame heater is a heater to understand that heats a certain part of the body of the device, namely the directed to the closure element and the open side of the body surrounding area.
• This frame heating can be performed circumferentially or the opening only partially, for example, U-shaped surrounded and has the purpose to prevent icing of the device in the region of the opening and thus in the region of the closure element, such as a door, flap or drawer.
• the heating of the outer skin of the device has the advantage that an undesirable formation of condensate on the outer skin of the device is prevented.
• the heating of the outer skin is thus designed such that the temperature of the outer skin is kept above the dew point of water.
• the heat pipe can be filled with water or with a water-containing solution as a heat transport medium.
• a heat pipe or heat pipe is based on the principle that on one side of the heat pipe evaporation of a heat transfer medium takes place and at another point and preferably in the other end of the heat pipe condensation takes place.
• heat is supplied in one area of the heat pipe and in the other area in which the condensation takes place, heat is released by the heat pipe. This amount of heat released can now be used according to the invention to form a frame heating or to heat the outer skin of the device.
• a separate frame heating which forms part of a refrigerant circuit, for example, can thus be dispensed with according to the invention, as well as a separate heating of the outer skin, for example by a heating foil.
• any other heat transfer media come into consideration, by means of which the heat pipe is filled.
• the heat pipe is designed as a vitreous thermal heat pipe.
• the heat pipe thus preferably has no capillaries for transporting the heat transport medium.
• the condenser communicates with at least one heat accumulator and is preferably arranged in a liquid bath, in particular in a water bath.
• This embodiment of the invention utilizes the fact that the heat energy of the heat accumulator charged by the condenser with heat can be used to operate the heat pipe and thus to transfer the heat to another location of the apparatus.
• the condenser may be arranged, for example, in the heat storage, such as in a liquid bath or with a heat storage in other ways in connection.
• the present invention thus relates not only to the case where the at least one heat pipe is in thermal contact with the condenser, but also to the case where the at least one heat pipe is in thermal contact with the heat accumulator, which in turn is in thermal contact with the condenser ,
• the heat pipe is in direct contact with the outer skin. It is sufficient if a thermal connection between the outer skin of the device is so far that a condensation on the outer skin can be reliably prevented.
• exactly one heat pipe is arranged.
• the device may also have a plurality of heat pipes, which are directly or indirectly in thermal contact with the condenser or with the heat storage of the condenser.
• the at least one heat pipe by means of the at least one heat pipe, a large part of the heat quantity accumulating in the condenser is dissipated. It is conceivable, for example, that more than 50% and preferably more than 80% of the liquid accumulating heat quantities are removed by means of at least one heat pipe.
• the embodiment relates to a refrigerator and / or freezer with a full vacuum insulation.
• This is an insulation to understand in which the body consists of at least 90% of the insulating surface of a contiguous Vakuumdämmraum.
• the vacuum insulation chamber has at least one vacuum insulation body, which preferably has a foil bag which serves as a covering of the vacuum insulation body and in which a core material, for example perlite, is located.
• the film bag is vacuum-tight welded and has a vacuum inside, so that the heat transfer is correspondingly difficult.
• the envelope of the film bag is a diffusion-tight enclosure, by means of which the gas input in the film bag is so greatly reduced that the gätragtrag-related increase in the thermal conductivity of the resulting Vakuumdämm stressess is sufficiently low over its lifetime away.
• the life span is, for example, a period of 15 years, preferably 20 years and more preferably 30 years.
• the increase in the thermal conductivity of the vacuum insulation body due to the introduction of gas is ⁇ 100% and particularly preferably ⁇ 50% over its service life.
• the area specific gas transmission rate of the cladding is ⁇ 10-5 mbar * 1 / s * m 2, and more preferably ⁇ 10-6 mbar * 1 / s * m 2 (measured according to ASTM D-3985).
• This gas passage rate applies to nitrogen and oxygen.
• low gas flow rates are preferably in the range of ⁇ 10-2 mbar * I / s * m 2 and more preferably in the range of ⁇ 10-3 mbar * I / s * m 2 (measured according to ASTM F - 1249-90).
• the above-mentioned small increases in the thermal conductivity are achieved by these low gas passage rates.
• the vacuum insulation body can be arranged in the body and / or in the closure element, by means of which the body can be closed.
• the present invention is not limited to such full vacuum refrigerators or freezers.
• the invention also includes the case that a conventional thermal insulation, for example in the form of PU foam is present.
• the refrigerator or freezer according to the invention has a refrigerant circuit, the at least one compressor, at least one downstream of this condenser, at least one downstream throttle, in particular capillary and at least one evaporator, in which enters the capillary leaving the refrigerant.
• the refrigerant After flowing through the evaporator, the refrigerant passes back to the compressor via a suction line.
• the evaporator absorbs heat from the cooled interior, with the refrigerant evaporating.
• the condenser is used to condense the refrigerant, whereby heat is generated.
• the condenser is according to the embodiment in a heat storage, such as in a water bath.
• the heat accumulator communicates with one or more heat pipes, ie heat pipes. These are filled with water and designed such that the heat transfer medium therein is vaporized during operation of the heat medium circuit within the heat pipe.
• the heat pipe is at its other end with the outer skin, which is preferably designed as a sheet metal jacket, in conjunction.
• the condensation of the heat transfer medium takes place, whereby heat is released, which is transmitted to the outer skin of the device.
• a heat pipe runs from the condenser or from the heat storage mentioned to a frame heating of the device, which extends around the open side of the body of the device and which serves to heat the door stop surface. This heat pipe thus also causes a heating of a certain area of the device and serves as a frame heating in this case.
