Description

Technical Field

[0001] The invention relates to a heating and cooling module block for a heating and cooling module, a heating and cooling module having such a heating and cooling module block and a method for producing such a heating and cooling module block. Background Art

[0002] Diffusion-proof and pressure-resistant connections are required between the components of air conditioning systems and heat pumps. According to the knowledge in-house, metal pipes can be used for this purpose, which are usually closed by soldering or welding and / or flange connections in combination with sealing rings. However, this type of connection technology is only reliable to a limited extent, because, for example, soldered connections are very dependent on the selected process parameters, are also very complex to manufacture, and require a large installation space. In addition, the number of connection points increases the risk of leaks and thus the risk of harmful refrigerants being released into the environment.

[0003] In order to reduce the number of the above-mentioned connections, according to the results of the company's internal research, a heating and cooling module block that is mainly one-piece and has pipes passing through it can also be used. However, this heating and cooling module block can be uniformly heated after a certain period of operation, whereby heat can also be transferred between the pipes extending through the heating and cooling module block, and heat transfer between these pipes is undesirable. This is not conducive to the efficiency of the heat pump having such a heating and cooling module block. Summary of the invention

[0004] Against this background, it is an object of the present invention to provide an improved heating and cooling module block.

[0005] Therefore, a heating and cooling module block for a heating and cooling module is proposed. The heating and cooling module block comprises a material for making the heating and cooling module block, a plurality of pipes embedded in the material, a first section through which a portion of the pipes pass, and a second section through which another portion of the pipes pass, wherein heat conduction within the first section or within the second section is superior to heat conduction between the first section and the second section.

[0006] Since the heat conduction in the first section or in the second section is better than the heat conduction between the first section and the second section, the pipes extending through the first section and the pipes extending through the second section can be thermally separated from each other. However, the pipes extending in the respective sections are not thermally separated from each other, so that good heat transfer between the pipes can be achieved in the respective sections. This improves the efficiency of the heating and cooling module with such a heating and cooling module block. However, in specific areas of the heating and cooling module block, the heat transfer can also be intentionally promoted, which can then also increase the efficiency of the heating and cooling module.

[0007] The heating and cooling module or the heating and cooling module block can be suitable for use in a building. Alternatively, the heating and cooling module or the heating and cooling module block can also be used in a motor vehicle, such as a passenger car. The heating and cooling module or the heating and cooling module block can then, for example, be part of a vehicle air conditioning system. The heating and cooling module can be operated both in a heating mode and in a cooling mode. Therefore, the heating and cooling module can also be referred to as an air conditioning module.

[0008] Preferably, the heating and cooling module is a heat pump or part of a heat pump. Thus, the heating and cooling module block can also be part of a heat pump. In the present case, a "heat pump" is understood to be a machine which, using technical work, absorbs thermal energy from a reservoir with a lower temperature (in the present case, for example, the environment of the machine) and transfers it as useful heat together with the drive energy to a system to be heated at a higher temperature (in the present case, for example, the interior of a building or a vehicle). Thus, the heating and cooling module can also be referred to as a heat pump heating and cooling module or heat pump module.

[0009] The material for manufacturing the heating and cooling module block is preferably a light metal. For example, an aluminum alloy or a magnesium alloy can be used as the material for the heating and cooling module block. However, plastic and / or fiber composite materials can also be used at least partially.

[0010] Preferably, the heating and cooling module block is manufactured from the material as a one-piece component. This means that the heating and cooling module block is in particular one-piece or single-piece. However, this is not absolutely necessary. The fact that the heating and cooling module block is a "single-piece" or "one-piece" component in particular means that the heating and cooling module block does not consist of different subcomponents, but forms a single continuous component, i.e. the heating and cooling module block. The heating and cooling module block is particularly preferably an integral component. In the present case, "one-piece material" in particular means that the heating and cooling module block is made of the same material as a whole, for example of an aluminum alloy as described above.

[0011] Alternatively, the heating and cooling module block can also be multi-piece or multi-part. In this case, "multi-part" or "multi-piece" means that the heating and cooling module block can be composed of different subcomponents. For example, the heating and cooling module block can be divided into two parts and have, for example, a base body and a cover. For example, the pipeline is incorporated into the base body. The pipeline can then be closed with the help of the cover. This means that the wall of the pipeline can be at least partially arranged on the base body and partially arranged on the cover. For example, if the pipeline has a rectangular cross section and therefore also has rectangular walls, one side of the rectangular cross section can be arranged on the cover, whereby the other three sides of the rectangular cross section can be arranged on the base body. The heating and cooling module block can also be divided into two halves or shell halves.

[0012] The pipes may be part of a refrigeration circuit and / or part of a cooling circuit. In particular, this means that at least a part of the refrigeration circuit and / or a part of the cooling circuit may extend through the heating and cooling module block. If the refrigeration circuit extends through the heating and cooling module block, the pipes or at least a part of the pipes are filled with a refrigerant. If the cooling circuit extends through the heating and cooling module block, the pipes or at least a part of the pipes are filled with a coolant.

[0013] A "refrigerant" transfers enthalpy from the refrigerant to the environment. The difference with a "coolant" is that a refrigerant in a cooling circuit can transfer enthalpy along a temperature gradient, so that the ambient temperature can even be higher than the temperature of the object to be cooled when energy is applied, whereas a coolant can only transfer enthalpy against the temperature gradient to a point at a lower temperature in the cooling circuit. For example, 1,1,1,2-tetrafluoroethane (R-134a), carbon dioxide (R744) or any other suitable refrigerant can be used as a refrigerant. An example of a refrigerant is water.

[0014] In the present case, the fact that the pipes are "embedded" or "inserted" into the material means in particular that the pipes are preferably embedded or inserted into the bulk material of the heating and cooling module block by a material removal process such as drilling, milling and / or etching, in particular in the form of cavities, recesses, holes or grooves. However, the pipes can also be "embedded" or "inserted" into the heating and cooling module block by "building" the heating and cooling module block around the pipes in an additive manufacturing process or a generative manufacturing process, in particular in a 3D printing process. The pipes can also be "embedded" or "inserted" into the material by casting molten material around one or more salt cores. The pipes are then formed by flushing away the one or more salt cores.

[0015] "Inserted" in particular also means that the pipes are at least partially formed as one or more cavities arranged in the material. This means that no additional components, such as pipes, extend through the heating and cooling module block for conducting the refrigerant and / or coolant. This also means that during operation of the heating and cooling module, the refrigerant and / or coolant can come into direct contact with the material. However, this does not exclude the possibility that the pipes are at least partially coated internally with a coating, such as an anti-corrosion coating.

[0016] The heating and cooling module block is preferably block-shaped or plate-shaped. "Block-shaped" means that the heating and cooling module block is rectangular or box-shaped. "Plate-shaped" means that the thickness of the heating and cooling module block is significantly smaller than its width and depth. The heating and cooling module block is particularly preferably plate-shaped. Therefore, the heating and cooling module block can also be called a heating and cooling module plate. This means that the terms "heating and cooling module block" and "heating and cooling module plate" can be used interchangeably.

[0017] The first section and the second section together form the heating and cooling module block, preferably as a one-piece component. This means in particular that the first section and the second section can be inseparably connected to one another. In particular, the first section and the second section together form the heating and cooling module block, in particular as a one-piece component. For example, two pipes pass through the first section and two further pipes, which are different from the above-mentioned pipes, pass through the second section.

[0018] For example, the heat flow in the first section or in the second section or The heat flow between the first section and the second section may be greater than the heat flow between the first section and the second section. Here, "heat flow" or "heat flux" should be understood as a physical quantity used to quantitatively describe the heat transfer process. describes the amount of thermal energy δQ transferred from a high temperature location to a low temperature location within a time interval δt. Then the following formula applies:

[0019]

[0020] In this case, for example, the heat flow between the above-mentioned pipes extending through the first section or between the pipes extending through the second section The heat flow between the pipes of the first section and the pipes of the second section may be greater.

[0021] In this context, "heat transfer", "heat diffusion" or "conduction" refers to a mechanism for transferring thermal energy. Heat always flows only in the direction of lower temperature. No thermal energy is lost in the process. The law of conservation of energy applies. For example, by providing a thermal insulation element between the first section and the second section (for example in the form of a cavity or a thermal insulation element made of a different material than the heating and cooling module block), the heat transfer within the first section or within the second section can be made superior to the heat transfer between the first section and the second section.

[0022] According to one embodiment, the first section has a first cross-sectional area, wherein the second section has a second cross-sectional area, and wherein the first cross-sectional area is smaller than the second cross-sectional area.

[0023] The first cross-sectional area and the second cross-sectional area can have any geometric shape, respectively. For example, the first cross-sectional area and the second cross-sectional area can be rectangular, in particular square, respectively. For example, the second cross-sectional area can be a multiple of the first cross-sectional area. Because the second cross-sectional area is larger than the first cross-sectional area, the temperature rise of the second section can be greater than the temperature rise of the first section during the operation of the heating and cooling module block. As a result, the heat transfer between the pipes arranged in the second section is better than the heat transfer between the pipes arranged in the first section. In addition, the heat transfer from the first section to the second section and from the second section to the first section is also suppressed by the different cross-sectional areas. In particular, the first section emits more heat to the environment faster and / or more than the second section.

[0024] According to another embodiment, the first section has a first width, wherein the second section has a second width, and wherein the first width is smaller than the second width.

[0025] Preferably, the heating and cooling module block is provided with a coordinate system having a first spatial direction (width direction or x-direction), a second spatial direction (height direction or y-direction) and a third spatial direction (depth direction or z-direction). These directions are oriented perpendicular to each other. For example, the first width and the second width can be oriented along the x-direction respectively. The second width can be a multiple of the first width.

[0026] According to another embodiment, the heating and cooling module block has a cavity arranged between the first section and the second section.

[0027] The cavity is preferably filled with air. However, the cavity may also be filled with another gas, such as nitrogen. The cavity arranged between the first section and the second section acts as a thermal insulator and prevents or inhibits heat transfer from the first section to the second section and from the second section to the first section. For example, the cavity may be formed by casting the molten material of the heating and cooling module block around a salt core. After the material solidifies, the salt core may be flushed away, thereby forming the cavity.

[0028] According to a further embodiment, the heating and cooling module block has webs which are guided through the cavity and connect the first section in one piece to the second section.

[0029] The width of the web can be used to set whether a better or worse heat transfer is to be achieved from the first section to the second section and from the second section to the first section via the web. The cavity is preferably arranged between the webs. In particular, at least two webs are provided. A first web and a second web can be provided.

[0030] According to another embodiment, the heating and cooling module block has a thermal insulation element accommodated in the cavity, wherein the thermal insulation element is made of a substance having a lower thermal conductivity than the material.

[0031] "Thermal conductivity", "thermal conductivity" or "thermal conductivity" is a material property which determines the heat flow through a substance based on heat conduction. Thermal conductivity indicates how well a substance conducts heat, or how suitable it is for thermal insulation. The lower the thermal conductivity value, the better the thermal insulation. For example, during the manufacture of the heating and cooling module block, the thermal insulation element can be encapsulated with the material of the heating and cooling module block. The thermal insulation element is preferably made of a substance with poor thermal conductivity. For example, the thermal insulation element can be made of glass wool or a ceramic material, in particular of a foam substance.

[0032] According to another embodiment, the thermal insulation element is surface coated in order to form a firmly bonded connection with the material.

[0033] In the case of a firmly bonded connection, the connection partners are held together by atomic or molecular forces. A firmly bonded connection is a non-detachable connection that can only be separated by destroying the connection device and / or the connection partners. Alternatively, the thermal insulation element can also be connected to the material in a form-fitting manner. A form-fitting connection is formed by at least two connection partners engaging or enveloping each other. For example, the material can engage with the thermal insulation element on a microscopic level.

[0034] According to another embodiment, the heating and cooling module block comprises a thermally conductive element surrounded by the material, wherein the thermally conductive element is made of a substance having a higher thermal conductivity than the material.

[0035] For example, the heat conducting element can be made of copper. However, other substances can also be used for the heat conducting element. For example, the heat conducting element can also be made of graphite. The heat conducting element can be encapsulated with the material of the heating and cooling module block.

[0036] According to another embodiment, the heat conducting element is surface coated in order to form a firm adhesive connection with the material.

[0037] Additionally or alternatively, a form-locking connection can also be formed between the heat-conducting element and the material.Alternatively or additionally, the heat-insulating element and / or the heat-conducting element can also be heated before the heat-insulating element and / or the heat-conducting element are coated with the molten material of the heating and cooling module block.

[0038] According to another embodiment, the heat conducting element is arranged between two adjacent pipes passing through the first section and / or between two adjacent pipes passing through the second section in order to improve heat conduction between the two adjacent pipes.

[0039] In particular, the heat insulating element is arranged between the first section and the second section, thereby preventing or at least inhibiting heat transfer between the first section and the second section. In contrast, the heat conducting element in the first section and / or in the second section improves heat conduction between the respective adjacent pipes.

[0040] According to another embodiment, the heat conducting element extends along the course of two adjacent pipes passing through the heating and cooling module block.

[0041] In particular, this means that, for example, the heat-conducting element is arranged at a constant distance from the pipeline and can, for example, extend along the curvature of the pipeline passing through the heating and cooling module block.

[0042] Furthermore, a heating and cooling module having at least one such heating and cooling module block is proposed, wherein the heating and cooling module is a heat pump.

[0043] As mentioned above, the heating and cooling module can be used for stationary applications, for example in building technology. However, the heating and cooling module can also be part of a vehicle, in particular a motor vehicle.

[0044] In addition, a method for manufacturing such a heating and cooling module block is proposed. The method comprises the following steps: (a) melting a material; (b) casting the molten material, so that the heating and cooling module block is manufactured and the heat conduction within the first section or within the second section is better than the heat conduction between the first section and the second section.

[0045] For example, the heating and cooling module block can be manufactured by a die-casting process. Here, molten material is poured into a die-casting mold to form the heating and cooling module block. In order to form a cavity as described above, a salt core as described above can be inserted into the die-casting mold. In addition, thermal insulation elements and / or heat-conducting elements can also be inserted into the die-casting mold. Preferably, the molten material is cast during step (b) so that the heating and cooling module block is manufactured as a one-piece component. However, as described above, this is not absolutely necessary. The heating and cooling module block can also be a multi-part component. In this case, for example, the above-mentioned base body and cover can be manufactured separately from each other, in particular by casting.

[0046] According to one embodiment, during step (b), a cavity is formed in the material, the cavity being arranged between the first section and the second section.

[0047] As mentioned above, the cavity serves to thermally decouple the first section from the second section and vice versa.

[0048] According to another embodiment, during step (b), a heat insulating element made of a substance having a lower thermal conductivity than the material and / or a heat conducting element made of a substance having a higher thermal conductivity than the material is encapsulated with the molten material.

[0049] The number of thermal insulation elements and the number of thermally conductive elements is arbitrary. As mentioned above, the thermal insulation element and / or the thermally conductive element may be surface coated. Furthermore, the thermal insulation element and / or the thermally conductive element may be preheated before casting the molten material around the thermal insulation element and / or the thermally conductive element in order to achieve an improved bond between the material and the thermal insulation element and / or the thermally conductive element.

[0050] The embodiments and features described for the proposed heating and cooling module block apply correspondingly to the proposed heating and cooling module and / or the proposed method and vice versa.

[0051] In the present case, "one" is not necessarily to be understood as being limited to exactly one element. Instead, multiple elements may be provided, such as two, three or more. Any other counting words used herein should also not be understood to mean limiting the element to exactly the specified number. Instead, unless otherwise specified, the values ​​may fluctuate.

[0052] Other possible embodiments of the heating and cooling module block, the heating and cooling module and / or the method also include combinations of features or embodiments described above or below with respect to the embodiments that are not explicitly mentioned. A person skilled in the art will also add individual aspects, improvements or supplements to the corresponding basic forms of the heating and cooling module block, the heating and cooling module and / or the method.

[0060] In the figures, identical or functionally identical elements are provided with the same reference symbols, unless otherwise indicated.

[0061] Figure 1 A schematic diagram of an embodiment of a heating and cooling system 1 for a building 2 is shown. The heating and cooling system 1 can therefore be referred to as a building heating and cooling system. The building 2 can be, for example, a residential building, in particular a single-family house or a multi-family house, or an office building. The heating and cooling system 1 is suitable for heating and cooling the interior 3 of the building 2. The heating and cooling system 1 can therefore also be referred to as an air conditioning system.

[0062] However, the heating and cooling system 1 can also be used in a vehicle (not shown), in particular in a motor vehicle. In this case, the heating and cooling system 1 can be referred to as a vehicle heating and cooling system. The heating and cooling system 1 can be an air conditioning system, or a part of a vehicle air conditioning system.

[0063] The heating and cooling system 1 comprises a compact heating and cooling module 4 which can be arranged outside the building 2, ie in its environment 5, or in the interior 3 of the building 2. The heating and cooling module 4 can also be referred to as an air conditioning module.

[0064] If the heating and cooling module 4 is used in a building 2, it may also be referred to as a building heating and cooling module. If the heating and cooling module 4 is used in a vehicle, it may also be referred to as a vehicle heating and cooling module.

[0065] The heating and cooling module 4 has a refrigerant pipe block or a heating and cooling module block 6, in which a refrigerant circuit 7 is realized by means of holes, channels, cavities, etc., in which a refrigerant K circulates. The refrigerant K can be 1,1,1,2-tetrafluoroethane (R-134a) or any other suitable refrigerant. The heating and cooling module block 6 can also be called a valve block.

[0066] A "refrigerant" transfers enthalpy from the object to be cooled to the environment 5. The difference from a "coolant" is that a refrigerant in a refrigeration circuit can transfer enthalpy along a temperature gradient, so that with the supplied energy, the ambient temperature can even be higher than the temperature of the object to be cooled, whereas a coolant can only transfer enthalpy against the temperature gradient to a point with a lower temperature in a refrigeration circuit.

[0067] The heating and cooling module block 6 can be plate-shaped or cuboid-shaped. For example, the heating and cooling module block 6 can be made of an aluminum alloy or a magnesium alloy. However, the heating and cooling module block 6 can also be made of a copper alloy. The heating and cooling module block 6 is preferably one-piece, in particular a one-piece material component. However, the heating and cooling module block 6 can also be multi-component.

[0068] "One-piece" or "single-piece" means that the heating and cooling module block 6 is not composed of different parts, but is manufactured as a single part. "One-piece material" or "monolithic" means that the heating and cooling module block 6 is made of the same substance as a whole, for example, made of aluminum alloy. However, this does not exclude that the heating and cooling module block 6 has a cover or other openable and closable maintenance opening.

[0069] In particular, the heating and cooling module block 6 can also be multi-piece or multi-part. In the present case, "multi-piece" or "multi-part" means that the heating and cooling module block 6 can be composed of different subcomponents. For example, the heating and cooling module block 6 can be two-part and have, for example, a base and a cover. The heating and cooling module block 6 can also be divided into two halves or shell halves. However, in the following, it is assumed that the heating and cooling module block 6 is a one-piece component.

[0070] The refrigerant circuit 7 itself can be inserted into the heating and cooling module block 6 by, for example, drilling, milling, etching or other ablative machining processes. In this way, a diffusion-tight refrigerant circuit 7 is created with the smallest possible number of potential leak points.

[0071] Furthermore, the heating and cooling module block 6 can also be built "around" the refrigerant circuit 7 in an additive manufacturing process or a generative manufacturing process, in particular in 3D printing. The heating and cooling module block 6 can also be a casting, whereby the refrigerant circuit 7 can be realized by inserted cores that are removed after the heating and cooling module block 6 is completed.

[0072] The fact that the main refrigerant-carrying cavity of the refrigerant circuit 7 is functionally integrated into the solid heating and cooling module block 6 means that the bonding technology required to close the refrigerant circuit 7 can be significantly reduced compared to conventional piping.

[0073] The heating and cooling module block 6 thus allows lower leakage of the refrigerant K, reliable production compared to brazing processes, smaller dimensions and higher power density, and a high degree of flexibility, for example in terms of possible applications of the heating and cooling modules 4 .

[0074] By reducing the number of detachable connections, a hermetically sealed refrigerant circuit 7 can be realized with smaller dimensions, low refrigerant diffusion and simpler assembly. This reduces the use of environmentally harmful substances with high global warming potential, such as refrigerant K.

[0075] Preferably, the refrigerant circuit 7 implemented in the heating and cooling module block 6 also includes - as will be explained below - valves or valve devices, which can guide the refrigerant K to different chambers according to different operating modes of the heating and cooling module 4 and thus reverse the flow direction of the refrigerant K, and thus, for example, can realize circuit reversal or defrosting circuit. The valve bodies of these valves can be pressed into or glued into the heating and cooling module block 6, but for ease of maintenance, a detachable connection technology can also be used.

[0076] Furthermore, other functional components, such as buffer tanks, dryers or even sight glasses, can be integrated into the heating and cooling module block 6. These components can be fully functionally integrated into the heating and cooling module block 6 in the form of another cavity or in the form of components attached to the heating and cooling module block 6.

[0077] Furthermore, a cavity can also be provided in the heating and cooling module block 6 as a buffer tank, which cavity can accommodate a filter and / or a desiccant. Such a desiccant is usually changed within defined maintenance intervals. In order to be able to do this, it makes sense to provide for this purpose a detachable connection which allows access to the above-mentioned cavity and enables the desiccant to be replaced as part of a maintenance activity. Furthermore, the electronics required for the control valves and possibly a compressor and necessary sensors (such as temperature and / or pressure sensors) can also be integrated into the heating and cooling module block 6.

[0078] Depending on the requirements, the heat exchanger of the heating and cooling system 1 can be designed as a refrigerant-air heat exchanger, a refrigerant-water heat exchanger or a refrigerant-brine heat exchanger, depending on the respective heat sources and heat sinks used. It is also possible to integrate the above-mentioned compressor at least partially into the heating and cooling module block 6.

[0079] In the present case, the refrigerant circuit 7 implemented in the heating and cooling module block 6 comprises a refrigerant conduit 8, for example in the form of a bore in the heating and cooling module block 6, which leads from an interface 9 provided on the heating and cooling module block 6 to an interface 10 provided on the heating and cooling module block 6. The interfaces 9, 10 can be, for example, flanges or nozzles to which hoses or pipes can be attached.

[0080] The refrigerant line 8 comprises an expansion valve or throttle valve 11 integrated in the heating and cooling module block 6. The throttle valve 11 can be a throttling device, i.e. a constriction or throttling device provided on the refrigerant line 8 for expanding the refrigerant K. The flow through the throttle valve 11 can be in only one direction or in both directions.

[0081] A further refrigerant line 12 arranged in the heating and cooling module block 6 leads from the connection 13 to the connection 14 of the heating and cooling module block 6. A refrigerant line 15 leads from the connection 16 to the connection 17. The refrigerant line 18 implemented in the heating and cooling module block 6 connects the refrigerant lines 12, 15 to one another in a fluidic manner. The refrigerant line 18 has a valve 19, in particular a switching valve, which is also arranged in the heating and cooling module block 6.

[0082] A heat exchanger 22, in particular an air-refrigerant heat exchanger, which is also arranged outside the heating and cooling module block 6, is connected to the interfaces 10, 13 by means of refrigerant pipes 20, 21 arranged outside the heating and cooling module block 6. The refrigerant pipes 20, 21 can be pipes or hoses. The refrigerant pipes 20, 21 are flange-connected to the interfaces 10, 13. A fan or ventilator 23 is associated with the heat exchanger 22. The fan 23 can force an air flow to achieve an improved heat exchange.

[0083] The heat exchanger 26 is connected to the interfaces 9, 17 by means of refrigerant pipes 24, 25. The refrigerant pipes 24, 25 and the heat exchanger 26 are arranged outside the heating and cooling module block 6. However, the refrigerant pipes 24, 25 and / or the heat exchanger 26 can also be arranged at least partially inside the heating and cooling module block 6. The refrigerant pipes 24, 25 can be hoses or pipes. The refrigerant pipes 24, 25 are flange-mounted to the interfaces 9, 17. The heat exchanger 26 is preferably a refrigerant / heat transfer medium heat exchanger, in particular a refrigerant / water heat exchanger.

[0084] The heat exchanger 26 is suitable for transferring heat Q from the refrigerant circuit 7 to the heat transfer medium circuit 27 and vice versa. A heat transfer medium M, such as water, circulates in the heat transfer medium circuit 27. The heat transfer medium M is a coolant. In addition to the heat exchanger 26, the heat transfer medium circuit 27 also includes a heat exchanger 28, which is arranged in the interior 3 of the building 2. The heat exchanger 28 is a heat transfer medium-air heat exchanger. The heat exchanger 28 can be a radiator or a radiator. The heat transfer medium circuit 27 can be located at least partially in the heating and cooling module block 6.

[0085] A compressor or compactor 29 for compressing the refrigerant K is connected to the interfaces 14, 16. The compressor 29 is completely outside the heating and cooling module block 6. However, as described above, the compressor 29 can also be at least partially integrated into the heating and cooling module block 6. The compressor 29 comprises a compressor geometry 30 and a motor 31, in particular an electric motor, for driving the compressor geometry 30. The compressor geometry 30 can include compressor blades or pistons.

[0086] The function of the heating and cooling system 1 in the heating mode is explained below. The heating and cooling system 1 is used as a heat pump, in particular an air-water heat pump. By appropriately combining the heat exchangers 22, 26, 28, for example by using two refrigerant-liquid heat exchangers, a water-water heat pump can be created, or by combining two refrigerant-air heat exchangers an air-air heat pump can be created.

[0087] In the present case, a “heat pump” is understood to be a machine which, using technical work, absorbs thermal energy from a cooler reservoir (in the present case, the environment 5 ) and transfers it as useful heat together with drive energy to a warmer system to be heated (in the present case, the interior 3 of a building 2 ).

[0088] The heat exchanger 22 absorbs heat Q from the environment 5. The heat exchanger 22 acts as an evaporator to at least partially evaporate the refrigerant K. The refrigerant K absorbs heat Q. The refrigerant K is cold, has a low pressure, and is at least partially in a gaseous state. The refrigerant K is conveyed to the compressor 29 through the refrigerant pipes 12, 21 and compressed. Downstream of the compressor 29, the refrigerant K has a high temperature and a high pressure and is at least partially in a gaseous state.

[0089] Then, the refrigerant K is conveyed to the heat exchanger 26 through the refrigerant pipes 15, 24. The heat exchanger 26 serves as a condenser. The gaseous refrigerant K condenses in the heat exchanger 26 and releases heat Q to the heat transfer medium circuit 27. Downstream of the heat exchanger 26, the refrigerant K is liquid, has a high pressure and is hot.

[0090] Therefore, the refrigerant K is delivered to the throttle valve 11 through the refrigerant pipes 8, 25, where the pressure is reduced. Downstream of the throttle valve 11, the refrigerant K is liquid, has a low pressure and is very cold. The refrigerant K is delivered back to the heat exchanger 22 through the refrigerant pipes 8, 20, where it absorbs heat Q again.

[0091] The heat Q transferred to the heat transfer medium circuit 27 is transferred to the interior 3 by means of the heat exchanger 28 in order to heat it. The above process can be reversed in order to cool the interior 3. The heating and cooling system 1 is then in cooling mode.

[0092] Figure 2 A schematic cross-sectional view of one embodiment of a heating and cooling module block 6A as described above is shown.

[0093] A coordinate system is assigned to the heating and cooling module block 6A, which has a first spatial direction, width direction or x direction x, a second spatial direction, height direction or y direction y, and a third spatial direction, depth direction or z direction z. The directions x, y, z are oriented perpendicular to one another.

[0094] according to Figure 2The cross-sectional view of FIG. 6A extends perpendicularly to the channels, lines or pipes 32, 33, 34, 35 passing through the heating and cooling module block 6A. The pipes 32, 33, 34, 35 can be part of the refrigerant circuit 7 and / or the heat transfer medium circuit 27. For example, the pipes 32, 33, 34, 35 can be the aforementioned refrigerant pipes 8, 12, 15, 18, 20, 21, 24, 25, or other components of the refrigerant circuit 7 or the heat transfer medium circuit 27. The cross section of the pipes 32, 33, 34, 35 can be circular. However, this is not absolutely necessary. For example, the cross section of the pipes 32, 33, 34, 35 can also be rectangular, in particular square.

[0095] Each duct 32, 33, 34, 35 has an inner wall or wall 36, 37, 38, 39 that surrounds or surrounds the respective duct 32, 33, 34, 35. In other words, each duct 32, 33, 34, 35 is delimited from the material 40 of which the heating and cooling module block 6A is made by its respective wall 36, 37, 38, 39. Thus, the walls 36, 37, 38, 39 surround the ducts 32, 33, 34, 35.

[0096] Refrigerant K and / or heat transfer medium M circulate through the pipes 32, 33, 34, 35. For example, refrigerant K may circulate through all pipes 32, 33, 34, 35, heat transfer medium M may circulate through all pipes, or refrigerant K may circulate through some pipes 32, 33, 34, 35, and heat transfer medium M may circulate through other pipes 32, 33, 34, 35.

[0097] The pipes 32, 33, 34, 35 are integrated into the heating and cooling module block 6A. Here, "integrated" means that the pipes 32, 33, 34, 35 are inserted or directly processed into the material 40 of the heating and cooling module block 6A. The material 40 can also be called material or heating and cooling module block material.

[0098] The "insertion" or "machining" of the pipes 32, 33, 34, 35 into the material 40 can be done, for example, by drilling, milling and / or etching. Additive manufacturing or generative manufacturing processes, in particular 3D printing, can also be used. "Integrated" can also mean that the pipes 32, 33, 34, 35 are completely surrounded by the material 40. However, this is not absolutely necessary.

[0099] "Integrated" also means that the refrigerant K and / or the heat transfer medium M are in direct contact with the material 40. However, this does not exclude that the pipes 32, 33, 34, 35 are coated on the inside of their walls 36, 37, 38, 39, for example to prevent or hinder corrosion.

[0100] As mentioned above, the heating and cooling module block 6A can be made of an aluminum alloy or a magnesium alloy. This means that the material 40 can be an aluminum alloy or a magnesium alloy. However, other metal substances can also be used. In addition, the heating and cooling module block 6A can also be made of a plastic substance. Ceramic substances can also be used as the material 40.

[0101] The heating and cooling module block 6A is a one-piece component, in particular a monolithic component. The heating and cooling module block 6A can have a first section 41, through which the pipes 32, 33 extend, and a second section 42, through which the pipes 34, 35 extend. The number of sections 41, 42 is arbitrary. The sections 41, 42 are connected to each other in one piece, in particular as a monolithic component, and together form the heating and cooling module block 6A.

[0102] The first section 41 has a first cross-sectional area 43, which is indicated by shading. Correspondingly, the second section 42 has a second cross-sectional area 44, which is also indicated by shading. The first cross-sectional area 43 is smaller than the second cross-sectional area 44. The cross-sectional areas 43, 44 can be rectangular. However, the cross-sectional areas 43, 44 can in principle have any cross-sectional geometry.

[0103] For example, when viewed along the x-direction x, the first section 41 has a width b41. Correspondingly, when viewed along the x-direction x, the second section 42 has a width b42. The width b41 is smaller than the width b42.

[0104] Heat Q is transferred between the pipes 32, 33 and between the pipes 34, 35. Due to the fact that the first cross-sectional area 43 through which the pipes 32, 33 extend is smaller than the second cross-sectional area 44 through which the pipes 34, 35 extend, the transfer of heat Q between the pipes 32, 33 is reduced compared to the transfer of heat Q between the pipes 34, 35. Therefore, more heat Q is transferred per unit time between the pipes 34, 35 than between the pipes 32, 33.

[0105] Furthermore, since the first cross-sectional area 43 of the first segment is smaller than that of the second segment 42, the first segment 41 is cooled more and / or faster than the second segment 42. Since the width b41 of the first segment 41 is smaller than that of the second segment 42, it is more difficult for the heat Q to be transferred from the second segment 42 to the first segment 41, so that the first segment 41 is heated less than the second segment 42.

[0106] The heating and cooling module block 6A improves the efficiency of the heating and cooling system 1, in particular when operating as a heat pump. In particular, the heat distribution within the heating and cooling module block 6A is optimized. Uniform heating of the heating and cooling module block 6A is prevented. Due to the small first cross-sectional area 43, the amount of material 40 present in the first section 41 is small. This results in less heat Q being transferred from the pipe 32 to the pipe 33 or from the pipe 33 to the pipe 32. The opposite is true for the second section 42 and the pipes 34, 35.

[0107] Figure 3 A schematic cross-sectional view of another embodiment of a heating and cooling module block 6B as described above is shown.

[0108] Like the heating and cooling module block 6A, the heating and cooling module block 6B is block-shaped. The heating and cooling module block 6B is made of the material 40 as described above. The pipes 32, 33, 34, 35 surrounded or surrounded by the walls 36, 37, 38, 39 extend through the material 40. For example, heat Q is to be exchanged between the pipes 32, 33 and the pipes 34, 35. Preferably, there should be no exchange of heat Q between two pipes 32, 33 and two pipes 34, 35.

[0109] The heating and cooling module block 6B has a first section 41 and a second section 42, which together form a one-piece, in particular a monolithic heating and cooling module block 6B. A cavity 45 is arranged between the first section 41 and the second section 42, which cavity is incorporated into the material 40. The cavity 45 is surrounded or surrounded by a wall 46. The cavity 45 can extend along the pipe 33 and / or along the pipe 34.

[0110] For example, the cavity 45 can be made during the manufacture of the heating and cooling module block 6B by means of a salt core, which is cast around the molten material 40 and washed away after the material 40 solidifies. In addition, the cavity 45 can also be incorporated into the heating and cooling module block 6B by an ablation finishing process.

[0111] When viewed in the y-direction y, the cavity 45 is arranged between the pipes 33, 34 and prevents or hinders the transfer of heat Q from the first section 41 to the second section 42 or from the second section 42 to the first section 41. The first section 41 and the second section 42 are connected to each other only via webs 47, 48 arranged on both sides of the cavity 45. The webs 47, 48 are cross-sectional constrictions between the two sections 41, 42. The transfer of heat Q between the sections 41, 42 can only take place via the webs 47, 48. A first web 47 and a second web 48 are provided.

[0112] The cavity 45 can be filled with gas, in particular air. However, the cavity 45 can also be filled with other gases, such as nitrogen. In short, the cavity 45 hinders the transfer of heat Q between the two sections 41, 42, and therefore also hinders the transfer of heat Q between the pipes 32, 33 and the pipes 34, 35.

[0113] The transfer of heat Q between the pipe 34 and the pipe 35 should be improved compared to the pipes 32, 33. For this purpose, a heat conducting element 49 is provided between the pipe 34 and the pipe 35 when viewed in the y direction y. The heat conducting element 49 is encapsulated in the material 40 or surrounded by the material 40. The wall 50 of the heating and cooling module block 6B surrounds the heat conducting element 49.

[0114] The heat conducting element 49 is made of a substance having a higher thermal conductivity or coefficient of thermal conductivity than the material 40. This improves the transfer of heat Q between the pipes 34, 35. The heat conducting element 49 may be molded together with the material 40 during the manufacture of the heating and cooling module block 6B.

[0115] In the second section 42, the transfer of heat Q is increased by an insert in the form of a heat-conducting element 49. Although the transfer of heat Q is not inhibited in the first section 41, it is lower than in the second section 42 due to the absence of such a heat-conducting element 49. In addition, a cavity 45 is provided between the two sections 41, 42, which inhibits the transfer of heat Q. The cavity 45 prevents the different sections 41, 42 from influencing each other. However, the second section 42 can also have such a heat-conducting element 49 (not shown).

[0116] Figure 4 A schematic cross-sectional view of another embodiment of a heating and cooling module block 6C as described above is shown.

[0117] Heating and cooling module block 6C differs from heating and cooling module block 6B only in that cavity 45 is not filled with a gas but with an insulating element 51. All embodiments relating to heating and cooling module block 6B are correspondingly applicable to heating and cooling module block 6C and vice versa.

[0118] For example, during the manufacture of the heating and cooling module block 6C, the insulation element 51 can be molded together with the material 40. The insulation element 51 is made of a substance with poor thermal conductivity. For example, the insulation element 51 can be made of glass wool or a ceramic substance, especially a foam substance.

[0119] Figure 5 A schematic cross-sectional view of another embodiment of a heating and cooling module block 6D as described above is shown.

[0120] The heating and cooling module block 6D is made of a material 40 as described above, through which the ducts 32, 33, 34, 35 pass, which are bounded by walls 36, 37, 38, 39. The heating and cooling module block 6D has a first section 41 through which the ducts 32, 33 pass, and a second section 42 through which the ducts 34, 35 pass. The sections 41, 42 together form the heating and cooling module block 6D as a one-piece component, in particular a monolithic component.

[0121] As mentioned above, a heat insulating element 51 is arranged between the first section 41 and the second section 42, which is enclosed by the wall 46 of the heating and cooling module block 6D. The heat insulating element 51 thermally separates the sections 41, 42 from each other, so that heat Q cannot be transferred from the first section 41 to the second section 42, or at least the transfer is reduced. With the help of the heat insulating element 51, the pipes 32, 33 and the pipes 34, 35 are separated from each other.

[0122] As previously described, the heat conducting element 49 surrounded by the wall 50 of the heating and cooling module block 6D is placed between the pipes 32, 33. As previously described, the heat conducting element 49 surrounded by the wall 50 of the heating and cooling module block 6D is also placed between the pipes 34, 35. The heat conducting element 49 facilitates the transfer of heat Q from the pipe 32 to the pipe 33 and vice versa, and the transfer of heat Q from the pipe 34 to the pipe 35 and vice versa.

[0123] For example, during operation of the heating and cooling module block 6D, the hot first refrigerant K1 can be conveyed via the pipe 32, which transfers heat Q to the first heat transfer medium M1 conveyed via the pipe 33. Figure 5 In the orientation shown, the first refrigerant K1 enters the heating and cooling module block 6D at the top with a first temperature T1 and Figure 5 In the orientation shown, the second temperature T2 is at the bottom. The first temperature T1 is higher than the second temperature T2.

[0124] When the first refrigerant K1 flows through the heating and cooling module block 6D, it releases heat Q to the first heat transfer medium M1. The first heat transfer medium M1 enters the heating and cooling module block 6D at the third temperature T3 and leaves it again at the fourth temperature T4. The fourth temperature T4 is higher than the third temperature T3. The third temperature T3 is lower than the second temperature T2. The fourth temperature T4 is lower than the first temperature T1.

[0125] The cold second heat transfer medium M2 can be conveyed via the pipe 34, which transfers heat Q to the very cold second refrigerant K2 conveyed via the pipe 35. Figure 5 In the orientation shown, the second heat transfer medium M2 enters the heating and cooling module block 6D at the top at the fifth temperature T5 and Figure 5In the orientation shown, it leaves it again at the bottom at a sixth temperature T6. The fifth temperature T5 is higher than the sixth temperature T6.

[0126] When the second heat transfer medium M2 flows through the heating and cooling module block 6D, it transfers heat Q to the second refrigerant K2. The second refrigerant K2 enters the heating and cooling module block 6D at the seventh temperature T7 and leaves it again at the eighth temperature T8. Here, the eighth temperature T8 is higher than the seventh temperature T7. The seventh temperature T7 is lower than the fifth temperature T5. The sixth temperature T6 is lower than the eighth temperature T8.

[0127] At least in different embodiments of the heating and cooling module blocks 6B, 6C, 6D, the transfer of heat Q can be partially facilitated by means of heat conducting elements 49 so that individual regions of the heating and cooling module blocks 6B, 6C, 6D can be designed as heat exchangers.

[0128] In summary, on the one hand, thermal decoupling or suppression of heat Q transfer can be achieved, for example, by means of different widths b41, b42 of the cavity 45 and / or the thermal insulation element 51; on the other hand, targeted thermal coupling or promotion of heat Q transfer can be achieved, for example, by means of the heat conducting element 49.

[0129] For thermal decoupling, a substance with a lower thermal conductivity than the material 40 can be used for the thermal insulation element 51. To facilitate the transfer of heat Q, the material thickness of the heating and cooling module blocks 6A, 6B, 6C, 6D can be partially increased. To increase the thermal conductivity, a substance with a higher thermal conductivity than the material 40 is used for the thermal conductive element 49. To suppress the transfer of heat Q, the material thickness can be partially reduced, for example in the region of the webs 47, 48.

[0130] In the heating and cooling module blocks 6A, 6B, 6C, 6D, depending on the process, some areas should promote the transfer of heat Q, while other areas should prevent or at least hinder the transfer of heat Q. As mentioned above, if no construction measures are taken, the heating and cooling module blocks 6A, 6B, 6C, 6D will heat up evenly after a period of time and in certain areas will reach undesirable temperatures. This temperature may be too low and / or too high.

[0131] In principle, as mentioned above, there are at least two options for improving or preventing the transfer of heat Q. On the one hand, the shape can be changed as explained with reference to the heating and cooling module block 6A. On the other hand, components such as heat conducting elements 49 and / or heat insulating elements 51 can be added to the heating and cooling module blocks 6B, 6C, 6D.

[0132] When changing the shape, the approach is that if a substance or material is added, for example in the region of the second section 42 of the heating and cooling module block 6A, a greater transfer of heat Q occurs than if a substance or material is removed, for example in the region of the first section 41 of the heating and cooling module block 6A. If a greater transfer of heat Q is now to occur in certain regions of the heating and cooling module block 6A, a greater material thickness is implemented in these regions.

[0133] If, on the other hand, a lower transfer of heat Q is to take place in another specific area, then a substance or material is intentionally omitted, thereby setting a smaller material thickness. As a result, the heating and cooling module block 6A is no longer symmetrical in all planes, in particular with regard to its outer contour. In particular, the heating and cooling module block 6A has different widths b41, b42 over its entire length, at least in one area. This process can be used if external factors, such as the available installation space, are not limiting factors.

[0134] Adding elements in the form of cavity 45, heat conducting element 49 and / or heat insulating element 51 takes into account external space installation restrictions. The basic idea is to use elements in the form of cavity 45, heat conducting element 49 and / or heat insulating element 51, which have a higher or lower thermal conductivity than material 40 (e.g. aluminum).

[0135] For example, the air contained in the cavity 45 is well suited as a low thermal conductivity element. The thermal conductivity of air is about 0.0262 W / mK, compared to aluminum, which has a thermal conductivity of about 160 W / mK. If low thermal conductivity is desired in a particular area, a cavity 45 is formed at that point so that it actually acts as an insulator. As previously described, this cavity 45 can be filled with an insulating element 51 in the form of a foam or other insulator.

[0136] For example, the cavity 45 can be introduced into the material 40 subsequently by etching, drilling, milling, etc. The cavity 45 is particularly preferably introduced directly during the casting process, for example by inserting a salt core into the injection mold and flushing it out again after the molten material 40 has solidified.

[0137] Various metallic and non-metallic substances are suitable as heat-conducting elements 49 with high thermal conductivity. The ability of a substance to dissipate heat Q depends not only on its thermal conductivity but also on the density of the respective substance. For inserts in the form of heat-conducting elements 49 and / or heat-insulating elements 51, their expansion must be taken into account when the temperature of the molten material 40 changes after solidification. In addition, the melting point of the substance used for the heat-conducting elements 49 and / or heat-insulating elements 51 must not be lower than the melting point of the material 40.

[0138] Compared to aluminum, which has a thermal conductivity of about 160 W / mK, copper has a thermal conductivity of about 400 W / mK, silicon carbide has a thermal conductivity of about 490 W / mK, graphite has a thermal conductivity of about 2000 W / mK, and diamond has a thermal conductivity of over 2000 W / mK. All of the above can be used. Boron compounds can also be used.

[0139] For the heat conducting element 49, copper with a melting point of about 1060° C. is particularly preferred. If a high thermal conductivity is required, an insert made of a substance with a higher thermal conductivity is used as the heat conducting element 49, the volume of which is the same as the volume of the material 40 which is no longer present. This insert is still inserted into the melt. The outer dimensions of the heating and cooling module blocks 6B, 6C, 6D do not change, but the thermal conductivity is partially improved.

[0140] If heat transfer is desired between the material 40 and the heat-conducting element 49 and / or the heat-insulating element 51, it is necessary to ensure particularly good contact between the heat-conducting element 49 and / or the heat-insulating element 51 and the material 40 during the melting process and / or the recasting process. This can be ensured by a particular surface roughness of the heat-conducting element 49 and / or the heat-insulating element 51 to ensure good contact.

[0141] Furthermore, a contact intermediary layer may be introduced between the heat conducting element 49 and / or the heat insulating element 51 and the material 40. This may be achieved by applying a special surface coating to the heat conducting element 49 and / or the heat insulating element 51. The heat conducting element 49 and / or the heat insulating element 51 may also be heated to the temperature of the molten material 40 to improve contact formation.

[0142] Figure 6 A schematic block diagram of an embodiment of a method for manufacturing a heating and cooling module block 6A, 6B, 6C, 6D is shown.

[0143] In the method, the material 40 is melted in step S1. In step S2, the molten material 40 is cast, so that the heating and cooling module blocks 6, 6A, 6B, 6C, 6D are manufactured in particular as a one-piece component and the heat conduction in the first section 41 or in the second section 42 is superior to the heat conduction between the first section 41 and the second section 42. Step S2 can be carried out by means of a casting mold, in particular by means of a die-casting mold. The above-mentioned one-piece production is not absolutely necessary. The heating and cooling module blocks 6, 6A, 6B, 6C, 6D can also be manufactured in multiple parts.

[0144] During step S2, as described above, a cavity 45 can be formed in the material 40, which is arranged between the first section 41 and the second section 42. For this purpose, for example, a salt core can be inserted into the casting mold, which is washed away after the material 40 solidifies. A plurality of cavities 45 can also be formed.

[0145] During step S2 , alternatively or additionally, as described above, the heat insulating element 51 made of a substance with a lower thermal conductivity than the material 40 and / or the heat conducting element 49 made of a substance with a higher thermal conductivity than the material 40 may be encapsulated with the melted material 40 .

[0146] Although the invention has been described with reference to examples of embodiment, it can be modified in many ways.
