Definitions
- the invention relates to a refrigerator according to the preamble of claim 1 .
- Refrigerators have a condenser connected in a refrigerating circuit.
- the condenser is a heat exchanger by means of which the heat absorbed in the refrigeration process is released outside of the refrigerator to the ambient air.
- Different designs of condensers are used for this purpose: With statically ventilated condensers, the surface area is enlarged to provide better heat dissipation by means of sheet metal strips or wire arrays which connect the heat exchanger tubes to one another.
- the statically ventilated condenser is mounted on the rear of the refrigerator.
- there are forced-ventilation condensers which can be implemented with significantly smaller dimensions.
- a separate fan can be arranged between the condenser and a compressor for the purpose of dissipating the heat from the condenser by means of its air flow.
- U1 discloses a generic refrigerator in which the condenser is embodied as a tubular heat exchanger with a tube coil which has horizontally running linear tube sections which are interconnected via edge-side tube bends.
- the generic refrigerator has a latent heat accumulator which absorbs heat given off by the condenser.
- a change in the aggregate state takes place when the heat given off by the condenser is absorbed.
- the aggregate state is reversed again during a standstill time of the refrigerating circuit by dissipation of heat to the environment.
- the latent heat accumulator is in direct contact with the condenser tubes. In this way a direct thermal transition is provided from the condenser into the latent heat accumulator.
- the object of the invention is to provide a refrigerator in which the refrigerating capacity of the refrigerating circuit is increased by simple means.
- the invention is based on the knowledge that free flow cross-sections between the heat accumulator element and the condenser's middle tube sections, which run in particular horizontally and in a straight line, enable faster heat dissipation from the condenser. Contrary to the prior art, therefore, the heat accumulator element according to the invention is spaced apart from the tube sections of the condenser by at least one predefined air flow gap. In this way an additional natural convection takes place in the air flow gap obtained, thus assisting in accelerating the heat dissipation from the condenser.
- the surface area of the condenser can be enlarged by means of cooling structures.
- Such cooling structures can be provided on the front side and/or rear side on the tube coil of the condenser in the form of wire arrays.
- the condenser surface area can be increased in size by means of sheet metal strips which interconnect the tube sections.
- the front and rear-side cooling structures, together with the tube sections of the condenser, in each case delimit installation interspaces in which the heat accumulator element can be inserted.
- the heat accumulator element can in this case be arranged contactlessly, in particular roughly centrally, between two neighboring tube sections. In this way the heat accumulator element is spaced apart by the same gap dimensions from the upper and lower tube sections.
- the heat accumulator element can be designed in roughly a strip shape.
- a permanently correctly positioned arrangement of the heat accumulator element in the installation interspace between the neighboring condenser tube sections is imperative.
- an additional retaining element can be provided in the respective installation interspace in order to ensure positionally secure retention of the heat accumulator element.
- the retaining element can be in particular a retaining wire which is supported on the heat accumulator element in the installation interspace.
- the retaining element can be embodied on the front and/or rear cooling structure, in particular secured thereto by means of a welded joint.
- the heat accumulator element can be fixedly clamped inside the installation interspace between the front and rear cooling structures by means of a simple clamp connection.
- the cooling structure of the condenser can be implemented as a front and rear wire array.
- the heat accumulator element is installed by insertion into the laterally open installation interspace between neighboring condenser tube sections.
- the front and rear wires of the cooling structure bend apart in an elastically resilient manner, as a result of which the inserted heat accumulator element is securely held by the clamping forces applied by the wire arrays.
- a heat accumulator element can be arranged alternatively or in addition on the edge side in the region of the outer tube bends of the condenser. In this way the installation interspaces between the horizontally running linear tube sections can remain completely free in order to increase the flow conditions, while only the outer condenser tube bends on the edge side can be thermally coupled to the heat accumulator element.
- Heat accumulator elements can preferably be provided on opposite edge sides of the condenser in each case such that they can extend in the manner of frame strips along the edge sides of the condenser.
- the heat accumulator element can be threaded through the horizontally running condenser tube sections in a meandering shape at a roughly right-angled orientation with respect to said tube sections.
- the heat accumulator element can be folded on the end side in the manner of a loop around a tube section of the condenser and secured.
- the edge-side heat accumulator elements are embodied in the appliance side direction outside of the front and/or rear condenser cooling structures. In this way the heat accumulator elements are arranged in the appliance side direction so as not to be overlapping with the cooling structure. An adverse effect on the mode of operation of the cooling structure due to overlapping heat accumulator elements can therefore be avoided.
- the heat accumulator element can be routed in a meandering shape and roughly at right angles through the condenser tube sections in order to be retained on the condenser.
- the heat accumulator element can be mounted on the outside onto the outer tube bends of the condenser.
- the heat accumulator element can have at least one recess into which a tube bend of the condenser can project.
- the heat accumulator element can be a roughly U-shaped hollow profile part into the cavity of which tube bends of the condenser can project.
- the heat accumulator element can be embodied by way of example as an elongate extruded part, that is to say in material measured by the yard which is favorable for manufacturing processes.
- the hollow profile part mounted onto the condenser on the edge side can enclose the outer tube bends of the condenser in the manner of a cover.
- the present invention can be used both for statically ventilated condensers and for forced-ventilation condensers.
- the condenser is assigned a separate fan which generates an air flow through the condenser in order to dissipate the condenser's heat.
- the condenser can be arranged in a cooling air duct which is partly delimited by at least one heat accumulator element.
- the heat accumulator elements can be embodied as cooling air duct sidewalls between which the condenser is arranged. The heat accumulator elements can therefore take on a dual function, additionally being used as air guide parts.
- the heat accumulator element can have a material which changes its aggregate state upon absorbing heat given off in the refrigeration process.
- the change in aggregate state is reversed again during a standstill time of the refrigerating circuit through dissipation of heat to the environment.
- the material can be by way of example a material fixed in a matrix and having the same mechanical properties irrespective of the actual temperature.
- the relevant transition point for the change in the aggregate state can be warmer than the typical ambient temperatures or the temperatures defined in the standards for measuring the energy consumption of refrigerators.

Abstract
A refrigerator includes a condenser which is connected into a refrigerating circuit and embodied as a tubular heat exchanger having tube sections. At least one heat accumulator element is inserted into an installation interspace between the tube sections of the condenser. The heat accumulator element is arranged in spaced apart relationship to the tube sections of the condenser by at least one predefined air flow gap.
Description
- The invention relates to a refrigerator according to the preamble of claim 1.
- Refrigerators have a condenser connected in a refrigerating circuit. The condenser is a heat exchanger by means of which the heat absorbed in the refrigeration process is released outside of the refrigerator to the ambient air. Different designs of condensers are used for this purpose: With statically ventilated condensers, the surface area is enlarged to provide better heat dissipation by means of sheet metal strips or wire arrays which connect the heat exchanger tubes to one another. The statically ventilated condenser is mounted on the rear of the refrigerator. Alternatively thereto, there are forced-ventilation condensers which can be implemented with significantly smaller dimensions. A separate fan can be arranged between the condenser and a compressor for the purpose of dissipating the heat from the condenser by means of its air flow.
- DE 20 2006 007 585 U1 discloses a generic refrigerator in which the condenser is embodied as a tubular heat exchanger with a tube coil which has horizontally running linear tube sections which are interconnected via edge-side tube bends. In order to increase the efficiency of the refrigerating circuit the generic refrigerator has a latent heat accumulator which absorbs heat given off by the condenser. A change in the aggregate state takes place when the heat given off by the condenser is absorbed. The aggregate state is reversed again during a standstill time of the refrigerating circuit by dissipation of heat to the environment.
- In the generic refrigerator the latent heat accumulator is in direct contact with the condenser tubes. In this way a direct thermal transition is provided from the condenser into the latent heat accumulator.
- The object of the invention is to provide a refrigerator in which the refrigerating capacity of the refrigerating circuit is increased by simple means.
- The object is achieved by means of the features of claim 1. Advantageous developments of the invention are disclosed in the dependent claims.
- The invention is based on the knowledge that free flow cross-sections between the heat accumulator element and the condenser's middle tube sections, which run in particular horizontally and in a straight line, enable faster heat dissipation from the condenser. Contrary to the prior art, therefore, the heat accumulator element according to the invention is spaced apart from the tube sections of the condenser by at least one predefined air flow gap. In this way an additional natural convection takes place in the air flow gap obtained, thus assisting in accelerating the heat dissipation from the condenser.
- In order to provide more effective heat dissipation the surface area of the condenser can be enlarged by means of cooling structures. Such cooling structures can be provided on the front side and/or rear side on the tube coil of the condenser in the form of wire arrays. Alternatively the condenser surface area can be increased in size by means of sheet metal strips which interconnect the tube sections. The front and rear-side cooling structures, together with the tube sections of the condenser, in each case delimit installation interspaces in which the heat accumulator element can be inserted. According to the invention the heat accumulator element can in this case be arranged contactlessly, in particular roughly centrally, between two neighboring tube sections. In this way the heat accumulator element is spaced apart by the same gap dimensions from the upper and lower tube sections. The heat accumulator element can be designed in roughly a strip shape.
- A permanently correctly positioned arrangement of the heat accumulator element in the installation interspace between the neighboring condenser tube sections is imperative. For this purpose an additional retaining element can be provided in the respective installation interspace in order to ensure positionally secure retention of the heat accumulator element. The retaining element can be in particular a retaining wire which is supported on the heat accumulator element in the installation interspace. The retaining element can be embodied on the front and/or rear cooling structure, in particular secured thereto by means of a welded joint.
- Alternatively or in addition the heat accumulator element can be fixedly clamped inside the installation interspace between the front and rear cooling structures by means of a simple clamp connection.
- As mentioned above, the cooling structure of the condenser can be implemented as a front and rear wire array. In this case the heat accumulator element is installed by insertion into the laterally open installation interspace between neighboring condenser tube sections. As the heat accumulator is inserted into the installation interspace the front and rear wires of the cooling structure bend apart in an elastically resilient manner, as a result of which the inserted heat accumulator element is securely held by the clamping forces applied by the wire arrays.
- As already mentioned above, free flow cross-sections between the middle condenser tube sections running in a straight line are extremely important for effective transfer of the heat from the condenser to the environment. Against this background, a heat accumulator element can be arranged alternatively or in addition on the edge side in the region of the outer tube bends of the condenser. In this way the installation interspaces between the horizontally running linear tube sections can remain completely free in order to increase the flow conditions, while only the outer condenser tube bends on the edge side can be thermally coupled to the heat accumulator element.
- Heat accumulator elements can preferably be provided on opposite edge sides of the condenser in each case such that they can extend in the manner of frame strips along the edge sides of the condenser.
- To provide simple retention on the condenser, the heat accumulator element can be threaded through the horizontally running condenser tube sections in a meandering shape at a roughly right-angled orientation with respect to said tube sections. In this arrangement the heat accumulator element can be folded on the end side in the manner of a loop around a tube section of the condenser and secured.
- It is particularly preferred for effective heat dissipation from the condenser if the edge-side heat accumulator elements are embodied in the appliance side direction outside of the front and/or rear condenser cooling structures. In this way the heat accumulator elements are arranged in the appliance side direction so as not to be overlapping with the cooling structure. An adverse effect on the mode of operation of the cooling structure due to overlapping heat accumulator elements can therefore be avoided.
- As described above, the heat accumulator element can be routed in a meandering shape and roughly at right angles through the condenser tube sections in order to be retained on the condenser. Alternatively hereto, the heat accumulator element can be mounted on the outside onto the outer tube bends of the condenser. To provide a positive-locking connection the heat accumulator element can have at least one recess into which a tube bend of the condenser can project.
- Alternatively thereto, the heat accumulator element can be a roughly U-shaped hollow profile part into the cavity of which tube bends of the condenser can project. In this case the heat accumulator element can be embodied by way of example as an elongate extruded part, that is to say in material measured by the yard which is favorable for manufacturing processes. The hollow profile part mounted onto the condenser on the edge side can enclose the outer tube bends of the condenser in the manner of a cover.
- The present invention can be used both for statically ventilated condensers and for forced-ventilation condensers. In the case of such a forced ventilation the condenser is assigned a separate fan which generates an air flow through the condenser in order to dissipate the condenser's heat. In this case the condenser can be arranged in a cooling air duct which is partly delimited by at least one heat accumulator element. Preferably the heat accumulator elements can be embodied as cooling air duct sidewalls between which the condenser is arranged. The heat accumulator elements can therefore take on a dual function, additionally being used as air guide parts.
- In order to increase heat dissipation from the condenser, the heat accumulator element can have a material which changes its aggregate state upon absorbing heat given off in the refrigeration process. The change in aggregate state is reversed again during a standstill time of the refrigerating circuit through dissipation of heat to the environment. The material can be by way of example a material fixed in a matrix and having the same mechanical properties irrespective of the actual temperature. In this case the relevant transition point for the change in the aggregate state can be warmer than the typical ambient temperatures or the temperatures defined in the standards for measuring the energy consumption of refrigerators. By this means it is ensured that the heat accumulator element is cooled down again below the transition point during the refrigerating circuit standstill time. With dynamically ventilated condensers, the fan can be activated during the refrigerating circuit standstill time, as a result of which the condenser can be effectively cooled overall.
- Three exemplary embodiments of the invention are described below with reference to the attached figures, in which:
-
FIG. 1 shows in a perspective view from behind a refrigerator having a condenser with partially inserted heat accumulator element according to the first exemplary embodiment; -
FIG. 2 shows the heat accumulator element inserted into the condenser in an enlarged sectional view along the section plane I-I; -
FIG. 3 shows a view corresponding toFIG. 2 according to a variation; -
FIG. 4 shows a view corresponding toFIG. 2 according to a further variation; -
FIG. 5 shows an arrangement of the heat accumulator element on the condenser according to the second exemplary embodiment; -
FIG. 6 shows the heat accumulator element according to the second exemplary embodiment in a variation; and -
FIG. 7 shows a forced-ventilation condenser provided with heat accumulator elements according to the third exemplary embodiment. -
FIG. 1 shows in a partial view from behind a refrigerator 1 having acondenser 3 mounted on the rear wall of the housing. Thecondenser 3 is ventilated statically and has a tube coil running in a meander shape and having horizontal,linear tube sections 5 which are arranged spaced apart from one another in a vertical plane one above the other. Themiddle tube sections 5 according toFIG. 1 are connected to one another via lateral tube bends 6. - As front and rear cooling structures, the
condenser 3 haswire arrays FIG. 2 shows a detail of the condenser in a sectional side view. According thereto, wires of the front andrear wire arrays condenser tube sections 5 via connectingpoints 11. Together with thewire arrays tube sections 5 shown inFIG. 2 form aninstallation interspace 13, open in the appliance side direction in each case, into which can be inserted, according toFIG. 1 , aheat accumulator element 15 embodied in this case by way of example as strip-shaped. The heat accumulator element can be by way of example an elongate pouch filled with a material, wherein the material can change its aggregate state upon absorbing heat given off by the condenser in the refrigeration process. - As shown in
FIG. 2 , the strip-shapedheat accumulator element 15 is spaced apart from the upper and lowercondenser tube sections 5 in a contactless manner viaair flow gaps 17. Contrary to the prior art, therefore, there is no direct contact with thecondenser tube sections 5. Rather, flow conditions in the region of thecondenser 3 can be improved with the aid of theair flow gaps 17 to the extent that the efficiency of the heat dissipation from thecondenser 3 is increased. - For stable retention of the
heat accumulator element 15, thewire pieces 19 shown inFIG. 3 can be provided inside theinstallation interspace 13 as retaining elements which are fixed for example by way of a welded joint to the front andrear wire arrays FIG. 3 , theheat accumulator element 15 is reliably as well as permanently supported on the twowire pieces 19. - Alternatively to
FIG. 3 , the width of theheat accumulator element 15 can be dimensioned such that in the installed state clamping forces FK are exerted by thewire arrays heat accumulator element 15, as shown inFIG. 4 . In this case the wires of thewire arrays heat accumulator element 15 is installed in thecondenser 3 so that the strip-shapedheat accumulator element 15 can be introduced into theinstallation interspace 13. -
FIG. 5 shows in a second exemplary embodiment acondenser 3 provided on the rear side of the refrigerator and having aheat accumulator element 15. In contrast to the preceding figures, theheat accumulator element 15 according toFIG. 5 is oriented in the vertical direction as well as roughly at right angles with respect to the horizontalcondenser tube sections 5. In this case the strip-shapedheat accumulator element 15 is threaded through thetube sections 5 in roughly a meandering shape in the region of the laterally outer tube bends 6. In this way theinstallation interspace 13 between the horizontal,straight tube sections 5 can remain completely free, thereby enabling free air convection between thestraight tube sections 5 of thecondenser 3 without any adverse effect due to theheat accumulator element 15. - The left side of the
condenser 3 not shown inFIG. 5 is provided in the same way with a vertically arranged, strip-shapedheat accumulator element 15. Arranged between the two lateralheat accumulator elements 15 are thewire arrays condenser 3 without any adverse effect caused by inward-protruding heat accumulator elements. - The
upper end 21 of theheat accumulator element 15 shown inFIG. 5 is folded in the manner of a loop around the top-side tube section 5 of thecondenser 3 and fixed in place by means of anindicated fastening pin 23. -
FIG. 6 likewise shows aheat accumulator element 15 arranged on the edge side of thecondenser 3 in a modification of the exemplary embodiment according toFIG. 5 . As inFIG. 5 , here, too, only the right rear side of the refrigerator is shown. The left side not shown is essentially embodied mirror-symmetrically likewise with an edge-sideheat accumulator element 15. In contrast toFIG. 5 , theheat accumulator element 15 inFIG. 6 is a rigid, roughly U-shaped hollow profile part. The strip-shaped hollow profile part is mounted with its open side in the manner of a cover onto the edge-side tube bends 6 of thecondenser 3. The cavity delimited by theU limbs 24 of theheat accumulator element 15 is dimensioned such that the condenser tube bends 6 can be inserted into theheat accumulator element 15, with a clamping tension being built up in the process. As inFIG. 5 , inFIG. 6 thecooling structures heat accumulator elements 15. - In contrast to the preceding exemplary embodiments,
FIG. 7 shows a refrigerator having a forced-ventilation condenser 3 together with acompressor 25 as well as aseparate fan 27 arranged between thecondenser 3 and thecompressor 25. - The device combination shown in
FIG. 7 , consisting ofcondenser 3,fan 27 andcompressor 25, is arranged in amachine space 28 of the refrigerator. Said space is embodied in a rear section of the refrigerator close to the floor. - During operation the
fan 27 generates a cooling air flow I which is pulled through thecondenser 3. In this case the condenser is a finned heat exchanger. In order to avoid a leakage flow past thecondenser 3, thecondenser 3 is arranged in an airtightcooling air duct 30. - In
FIG. 7 , the coolingair duct 30 is delimited by the upper ceiling wall of themachine space 28 as well as by abottom base plate 32 on which the device combination stands. In the installation depth direction x, the coolingair duct 30 is delimited by two edge-sideheat accumulator elements 15 arranged in an upright position. These are mounted analogously toFIG. 6 laterally onto the edge-side condenser tube bends 6 and, acting in a dual function, delimit the coolingair duct 30 in an airtight manner. - Toward that end each of the
heat accumulator elements 15 can have, on its side facing the condenser, recesses into which the tube bends 6 can project in a positive-locking manner. -
