Description

[0001] HEATING AND COOLING MODULE BLOCK, HEATING AND COOLING MODULE AND

[0002] PROCEDURE

[0003] The present invention relates to a heating and cooling module block for a heating and cooling module, a heating and cooling module with such a heating and cooling module block and a method for producing such a heating and cooling module block.

[0004] A diffusion-tight and pressure-resistant connection is required between components of air conditioning systems and heat pumps. According to internal experience, metal pipes can be used for this purpose, which usually form a closed circuit through soldered or welded joints and / or flange connections in conjunction with sealing rings. However, this type of connection technology offers only limited process reliability, as soldered joints, for example, depend heavily on the selected process parameters and are also very complex to manufacture and require a large amount of installation space. Furthermore, the number of connection points increases the risk of leaks and thus the risk of climate-damaging refrigerants being released into the environment.

[0005] In order to reduce the number of aforementioned connections, it is also possible, according to internal company knowledge, to use a predominantly one-piece heating and cooling module block through which lines are routed. However, such a heating and cooling module block can heat up evenly after a certain period of operation, whereby heat can also be transferred between lines running through the heating and cooling module block, between which heat transfer is not desired. This is disadvantageous with regard to the efficiency of a heat pump with such a heating and cooling module block. Against this background, one object of the present invention is to provide an improved heating and cooling module block.

[0006] Accordingly, a heating and cooling module block for a heating and cooling module is proposed. The heating and cooling module block comprises a material from which the heating and cooling module block is made, a plurality of lines incorporated into the material, a first section through which a portion of the lines pass, and a second section through which another portion of the lines pass, wherein 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.

[0007] Because 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, it is possible to thermally separate the lines running through the first section and the lines running through the second section. However, the lines running within each section are not thermally separated, so that good heat transfer between the lines is possible within each section. This improves the efficiency of a heating and cooling module with such a heating and cooling module block. However, heat transfer can also be deliberately promoted in certain areas of the heating and cooling module block, which can then also increase the efficiency of the heating and cooling module.

[0008] The heating and cooling module or heating and cooling module block may be suitable for use in a building. Alternatively, the heating and cooling module or heating and cooling module block can also be used in a motor vehicle, for example, a passenger car. The heating and cooling module or heating and cooling module block can then, for example, be part of the vehicle's air conditioning system. The heating and cooling module can operate in both heating and cooling modes. Accordingly, the heating and cooling module can also be referred to as an air conditioning module.

[0009] Preferably, the heating and cooling module is a heat pump or part of a heat pump. Accordingly, the heating and cooling module block can also be part of a heat pump. A "heat pump" is understood here to be a machine that, by expending technical energy, absorbs thermal energy from a reservoir with a lower temperature, in this case, for example, the environment of the machine, and transfers it—together with the drive energy—as useful heat to a system to be heated with a higher temperature, in this case, for example, the interior of a building or vehicle. The heating and cooling module can therefore also be referred to as a heat pump heating and cooling module or a heat pump module.

[0010] The material from which the heating and cooling module block is made 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, plastics and / or fiber composite materials can also be used, at least in some sections.

[0011] Preferably, the heating and cooling module block is manufactured from the material as a single-piece component. Thus, the heating and cooling module block is, in particular, single-piece or one-piece. However, this is not mandatory. The fact that the heating and cooling module block is a "single-piece" or "one-piece" component means, in particular, that the heating and cooling module block is not composed of different subcomponents, but rather forms a single, continuous component, namely the heating and cooling module block. Particularly preferably, the heating and cooling module block is a single-piece component. "Single-piece" means, in particular, that the heating and cooling module block is made entirely of the same material, for example, from an aluminum alloy as mentioned above.

[0012] Alternatively, the heating and cooling module block can also be multi-part or multi-part. "Multi-part" or "multi-part" in this context means that the heating and cooling module block can be composed of different subcomponents. For example, the heating and cooling module block can be two-part and have, for example, a base body and a cover. For example, the lines are incorporated into the base body. The lines can then be closed using the cover. Thus, walls of the lines can be provided at least in sections on the base body and in sections on the cover. In the event that the lines have, for example, a rectangular cross-section and thus also rectangular walls, one side of the rectangular cross-section can be provided on the cover, while three further sides of the rectangular cross-section can be provided on the base body.The heating and cooling module block can also be divided into two halves or housing halves.

[0013] The lines can be part of a refrigeration circuit and / or part of a cooling circuit. This means, in particular, that at least part of a refrigeration circuit and / or part of a cooling circuit can run through the heating and cooling module block. If a refrigeration circuit runs through the heating and cooling module block, the lines, or at least part of the lines, are filled with a refrigerant. If a cooling circuit runs through the heating and cooling module block, the lines, or at least part of the lines, are filled with a coolant.

[0014] A "refrigerant" transports enthalpy from a cooled object to the environment. The difference from a "coolant" is that a refrigerant in a refrigeration cycle can transport enthalpy along a temperature gradient, so that, with the application of added energy, the ambient temperature may even be higher than the temperature of the object to be cooled. A cooling agent, however, is only capable of transporting enthalpy against the temperature gradient to a lower temperature location in a refrigeration cycle. Examples of refrigerants include 1,1,1,2-tetrafluoroethane (R-134a), carbon dioxide (R744), or any other suitable refrigerant. An example of a coolant is water.

[0015] In this case, the fact that the lines are "worked" or "introduced" into the material means, in particular, that the lines are preferably worked or introduced into the block-shaped material of the heating and cooling module block by a material-removing process, such as drilling, milling, and / or eroding, in particular in the form of cavities, recesses, bores, or grooves. However, the lines can also be "worked" or "introduced" into the heating and cooling module block by building the heating and cooling module block around the lines in an additive or generative manufacturing process, in particular in a 3D printing process. The lines can also be "worked" or "introduced" into the material by casting the molten material around one or more salt cores. The lines are then formed by rinsing the salt core(s).

[0016] "Incorporated" also means, in particular, that the lines are at least partially formed as a cavity or cavities provided in the material. This means that no additional components, such as pipes, for conveying the refrigerant and / or coolant run through the heating and cooling module block. This also means that the refrigerant and / or coolant can come into direct contact with the material during operation of the heating and cooling module. However, this does not preclude the lines from being coated, at least in sections, on the inside with a coating, for example, a corrosion-inhibiting coating.

[0017] The heating and cooling module block is preferably block-shaped or plate-shaped. "Block-shaped" in this context means that the heating and cooling module block is cuboid-shaped 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. The heating and cooling module block can therefore also be referred to as a heating and cooling module plate. This means that the terms "heating and cooling module block" and "heating and cooling module plate" can be interchanged at will.

[0018] 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 lines are routed through the first section, while two further lines, different from the aforementioned lines, are routed through the second section.

[0019] For example, the heat flow Q or <t>within the first section or within the second section may be greater than between the first section and the second section. The term "heat flow" or "heat flux" is used here to describe a physical quantity for the quantitative description of heat transfer processes. The heat flow <t>describes the amount of heat energy öQ that is transferred from a location of high temperature to a location of low temperature in a period of time öt. The following then applies:

[0020] In this case, for example, the heat flow <t>between the aforementioned lines passing through the first section or between the lines passing through the second section may be greater than between the lines of the first section and the lines of the second section.

[0021] In this context, "heat conduction," "heat diffusion," or "conduction" refers to a mechanism for transporting thermal energy. Heat always flows toward lower temperatures. No heat energy is lost in the process. The law of conservation of energy applies. Heat conduction within the first section or within the second section can, for example, be improved over heat conduction between the first and second sections by providing a heat-insulating element between the first and second sections, for example, in the form of a cavity or a heat-insulating element made of a different material than the heating and cooling module block.

[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 each have any desired geometry. For example, the first cross-sectional area and the second cross-sectional area can each be rectangular, in particular square. 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 second section can heat up more than the first section during operation of the heating and cooling module block. As a result, heat transfer between the lines arranged within the second section is better than between the lines arranged within the first section. Furthermore, heat transfer from the first section to the second section and vice versa is also inhibited by the different sized cross-sectional areas.In particular, the first section releases heat to the environment faster and / or more than the second section.

[0024] According to a further 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 assigned a coordinate system with a first spatial direction, the width direction or x-direction, a second spatial direction, the height direction or y-direction, and a third spatial direction, the depth direction or z-direction. The directions are oriented perpendicular to each other. For example, the first width and the second width can each be oriented along the x-direction. The second width can be a multiple of the first width.

[0026] According to a further 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 can also be filled with another gas, such as nitrogen. The cavity located between the first and second sections serves as thermal insulation and prevents or inhibits heat transfer between the first and second sections, and vice versa. The cavity can be created, for example, by casting a salt core with the molten material of the heating and cooling module block.

[0028] The salt core can be flushed out after the material has solidified, forming the cavity.

[0029] According to a further embodiment, the heating and cooling module block has webs which are guided past the cavity and which integrally connect the first section to the second section.

[0030] The width of the webs can be adjusted to determine whether better or worse heat transfer via the webs from the first section to the second section and vice versa is to be achieved. 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.

[0031] According to a further embodiment, the heating and cooling module block has a thermal insulation element which is accommodated in the cavity, wherein the thermal insulation element is made of a material which has a lower thermal conductivity coefficient than the material.

[0032] The term "thermal conductivity coefficient," "thermal conductivity," or "thermal conductivity number" refers to a material property that determines the heat flow through a material based on heat conduction. Thermal conductivity indicates how well a material conducts heat or how well it is suited for thermal insulation. The lower the thermal conductivity value, the better the thermal insulation. For example, the thermal insulation element can be cast with the material of the heating and cooling module block during production. The thermal insulation element is preferably made of a material with poor thermal conductivity. For example, the thermal insulation element can be made of glass wool or a ceramic material, especially a foamed material.

[0033] According to a further embodiment, the thermal insulation element is surface-coated in order to create a material-locking connection with the material.

[0034] In bonded joints, the joining components are held together by atomic or molecular forces. Bonded joints are non-detachable connections that can only be separated by destroying the fasteners and / or the joining components. Alternatively, the thermal insulation element can also be connected to the material with a form-fit connection. Form-fit connections are created by the interlocking or interlocking of at least two joining components. For example, the material can engage with the thermal insulation element with a form-fit connection at a microscopic level.

[0035] According to a further embodiment, the heating and cooling module block has a heat-conducting element which is enclosed by the material, wherein the heat-conducting element is made of a material which has a higher thermal conductivity coefficient than the material.

[0036] For example, the heat-conducting element is made of copper. However, other materials 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 cast in the same material as the heating and cooling module block.

[0037] According to a further embodiment, the heat-conducting element is surface-coated to create a material-to-material bond with the material. Additionally or alternatively, a positive connection can also be created 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 encapsulated with the molten material of the heating and cooling module block.

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

[0039] In particular, the thermal insulation element is arranged between the first section and the second section, so that the transfer of heat between the first section and the second section is prevented or at least inhibited. In contrast, the thermal conduction element within the first section and / or within the second section improves the thermal conduction between the respective adjacent lines.

[0040] According to a further embodiment, the heat conducting element follows a course of the two adjacent lines through the heating and cooling module block.

[0041] This means, in particular, that the heat-conducting element is arranged, for example, at a constant distance from the lines and can, for example, follow a curve of the lines through the heating and cooling module block. Furthermore, a heating and cooling module with at least one such heating and

[0042] Cooling module block is proposed, whereby the heating and cooling module is a heat pump.

[0043] As previously mentioned, the heating and cooling module can be used for immobile applications, for example, in building services. However, the heating and cooling module can also be part of a vehicle, particularly a motor vehicle.

[0044] Furthermore, a method for producing such a heating and cooling module block is proposed. The method comprises the following steps: a) melting the material and b) pouring the molten material to produce the heating and cooling module block, and such that 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 using a die-casting process. Here, the molten material is poured into a die-casting mold to form the heating and cooling module block. To form a cavity as mentioned above, a core as mentioned above can be inserted into the die-casting mold. Furthermore, the thermal insulation element and / or the thermally conductive element can also be inserted into the die-casting mold. Preferably, during step b), the molten material is poured such that the heating and cooling module block is manufactured as a single-piece component. As mentioned above, however, this is not absolutely necessary. The heating and cooling module block can also be made of several parts. In this case, for example, the aforementioned base body and the cover can be manufactured, in particular cast, separately from one another.According to one embodiment, during step b) a cavity is formed in the material, which is arranged between the first section and the second section.

[0046] As previously mentioned, the cavity serves to thermally decouple the first section from the second section and vice versa.

[0047] According to a further embodiment, during step b), a thermal insulation element made of a material having a lower thermal conductivity coefficient than the material and / or a thermal conductivity element made of a material having a higher thermal conductivity coefficient than the material is cast with the molten material.

[0048] The number of thermal insulation elements and the number of thermal conduction elements is arbitrary. As previously mentioned, the thermal insulation element and / or the thermal conduction element can be surface-coated. Furthermore, preheating the thermal insulation element and / or the thermal conduction element before pouring the molten material around them is also possible in order to achieve an improved bond between the material and the thermal insulation element and / or the thermal conduction element.

[0049] The embodiments and features described for the proposed heating and cooling module block apply to the proposed heating and cooling module and / or to the proposed method accordingly and vice versa.

[0050] "One" in this case is not necessarily limited to a single element. Rather, multiple elements, such as two, three, or more, may also be included. Any other counting term used here should not be understood as implying a limitation to the exact number of elements mentioned. Rather, numerical deviations upwards and downwards are possible, unless otherwise stated.

[0051] Further possible implementations of the heating and cooling module block, the heating and cooling module, and / or the method also include combinations of features or embodiments described previously or below with respect to the exemplary embodiments that are not explicitly mentioned. In this case, the person skilled in the art will also add individual aspects, improvements, or additions to the respective basic form of the heating and cooling module block, the heating and cooling module, and / or the method.

[0052] Further advantageous configurations and aspects of the heating and cooling module block, the heating and cooling module, and / or the method are the subject of the dependent claims and the exemplary embodiments of the heating and cooling module block, the heating and cooling module, and / or the method described below. The heating and cooling module block, the heating and cooling module, and / or the method are explained in more detail below using preferred embodiments with reference to the accompanying figures.

[0054] Fig. 2 shows a schematic sectional view of an embodiment of a heating and cooling module block for the heating and cooling system according to Fig.i;

[0055] Fig. 3 shows a schematic sectional view of another embodiment of a heating and cooling module block for the heating and cooling system according to Fig. 1; Fig. 4 shows a schematic sectional view of another embodiment of a heating and cooling module block for the heating and cooling system according to Fig. 1;

[0056] Fig. 5 shows a schematic sectional view of another embodiment of a heating and cooling module block for the heating and cooling system according to Fig.i; and

[0057] Fig. 6 shows a schematic block diagram of an embodiment of a method for producing a heating and cooling module block according to Fig. 2, Fig. 3, Fig. 4 or Fig. 5.

[0058] In the figures, identical or functionally identical elements have been provided with the same reference numerals unless otherwise stated.

[0059] Figure 1 shows a schematic view of an embodiment of a heating and cooling system 1 for a building 2. 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 home or an apartment building, or an office building. The heating and cooling system 1 is suitable for heating and cooling an interior space 3 of the building 2. The heating and cooling system 1 can therefore also be referred to as an air conditioning system.

[0060] 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 part of an air conditioning system of the vehicle. The heating and cooling system 1 comprises a compact heating and cooling module 4, which can be arranged outside the building 2, i.e., in an environment 5 thereof, 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.

[0061] If the heating and cooling module 4 is used in a building 2, it can also be referred to as a building heating and cooling module. If the heating and cooling module 4 is used in a vehicle, it can also be referred to as a vehicle heating and cooling module.

[0062] The heating and cooling module 4 has a refrigerant line block or heating and cooling module block 6, in which a refrigerant circuit 7 is implemented by means of bores, channels, cavities, or the like, 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 referred to as a valve block.

[0063] A "refrigerant" transports enthalpy from a cooled item to the environment 5. The difference to a "coolant" is that a refrigerant in a refrigeration cycle can transport the enthalpy along a temperature gradient, so that with the expenditure of added energy the ambient temperature may even be higher than the temperature of the object to be cooled, whereas a cooling agent is only able to transport the enthalpy in a cooling cycle against the temperature gradient to a location of lower temperature.

[0064] The heating and cooling module block 6 can be plate-shaped or cuboid-shaped.

[0065] The heating and cooling module block 6 can be made, for example, from an aluminum alloy or a magnesium alloy. However, the heating and cooling module block 6 can also be made from a copper alloy. The heating and cooling module block 6 is preferably a one-piece component, in particular a single-piece component. However, the heating and cooling module block 6 can also be made from multiple parts.

[0066] "One-piece" or "single-piece" means that the heating and cooling module block 6 is not composed of different components, but is manufactured as a single component. "Single-piece" or "monolithic" means that the heating and cooling module block 6 is made entirely of the same material, for example, an aluminum alloy. However, this does not preclude the heating and cooling module block 6 from having a cover or other openable and closable maintenance openings.

[0067] In particular, the heating and cooling module block 6 can also be multi-part or multi-part. "Multi-part" or "multi-part" in this context 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 comprise, for example, a base body and a cover. The heating and cooling module block 6 can also be divided into two halves or housing halves. However, it is assumed below that the heating and cooling module block 6 is a single-part component.

[0068] The refrigerant circuit 7 itself can be introduced into the heating and cooling module block 6, for example, by drilling, milling, eroding, or other machining processes. This creates a diffusion-tight refrigerant circuit 7 with the smallest possible number of potential leak points.

[0069] Furthermore, the heating and cooling module block 6 can also be constructed "around" the refrigerant circuit 7 using an additive or generative manufacturing process, particularly 3D printing. The heating and cooling module block 6 can also be a cast component, whereby the refrigerant circuit 7 can be realized by inserted cores that are removed after the completion of the heating and cooling module block 6.

[0070] By functionally incorporating essential refrigerant-carrying cavities of the refrigerant circuit 7 into the solid heating and cooling module block 6, the joining techniques required to close the refrigerant circuit 7 can be significantly reduced compared to conventional piping.

[0071] With the heating and cooling module block 6, a lower leakage of the refrigerant K, process-reliable production compared to soldering processes, a smaller installation size with higher power density and a high degree of flexibility, for example with regard to the possible applications of the heating and cooling module 4, can be achieved.

[0072] By reducing the number of detachable connections, a hermetically sealed refrigerant circuit 7 with low refrigerant diffusion and increased ease of installation can be achieved with a compact design. This reduces the introduction of environmentally hazardous substances, such as refrigerant K, which has a high global warming potential.

[0073] 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 that can direct the refrigerant K into different cavities depending on different operating modes of the heating and cooling module 4, thereby reversing the flow direction of the refrigerant K and thus, for example, representing a circuit reversal or a defrost circuit. Valve bodies of these valves can be pressed or glued into the heating and cooling module block 6, although a detachable connection technology can also be used for ease of maintenance.

[0074] Furthermore, additional functional components such as a buffer tank, a dryer, or a sight glass can be integrated into the heating and cooling module block 6. These can be functionally integrated into the heating and cooling module block 6 either completely in the form of an additional cavity or in the form of an assembly attached to the heating and cooling module block 6.

[0075] Furthermore, a cavity can also be provided in the heating and cooling module block 6 as a buffer storage, which can contain a filter and / or a desiccant. Such desiccant materials are typically replaced at defined service intervals. To achieve this, it is advisable to provide a detachable connection for this purpose, which allows access to this aforementioned cavity and enables the replacement of the desiccant during service work. Furthermore, the electronics required to control the valves and, if applicable, a compressor, as well as the necessary sensors, such as temperature and / or pressure sensors, can also be integrated into the heating and cooling module block 6.

[0076] Depending on the heat source and heat sink used, heat exchangers of the heating and cooling system 1 can be designed as refrigerant-to-air heat exchangers, refrigerant-to-water heat exchangers, or refrigerant-to-brine heat exchangers. It is also possible to integrate the aforementioned compressor at least partially into the heating and cooling module block 6.

[0077] In the present case, the refrigerant circuit 7 implemented in the heating and cooling module block 6 comprises a refrigerant line 8, which is introduced, for example, as a bore into the heating and cooling module block 6 and 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, for example, be flanges or nozzles to which hoses or pipes can be attached.

[0078] The refrigerant line 8 comprises an expansion valve or throttle valve 11 incorporated into the heating and cooling module block 6. The throttle valve 11 can be a throttle, i.e., a constriction or throttle provided on the refrigerant line 8 for expanding the refrigerant K. The throttle valve 11 can be flowable in only one or in two directions.

[0079] Another refrigerant line 12 provided in the heating and cooling module block 6 leads from an interface 13 to an interface 14 of the heating and cooling module block 6. A refrigerant line 15 leads from an interface 16 to an interface 17. A refrigerant line 18 implemented in the heating and cooling module block 6 fluidically connects the refrigerant lines 12, 15. 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.

[0080] A heat exchanger 22, in particular an air-refrigerant heat exchanger, which is also located outside the heating and cooling module block 6, is connected to the interfaces 10, 13 by means of refrigerant lines 20, 21 arranged outside the heating and cooling module block 6. The refrigerant lines 20, 21 can be pipes or hoses. The refrigerant lines 20, 21 are flanged to the interfaces 10, 13. A fan or ventilator 23 is assigned to the heat exchanger 22. The fan 23 can force an air flow to enable improved heat exchange.

[0081] A heat exchanger 26 is connected to the interfaces 9, 17 by means of refrigerant lines 24, 25. The refrigerant lines 24, 25 and the heat exchanger 26 are arranged outside the heating and cooling module block 6. However, the refrigerant lines 24, 25 and / or the heat exchanger 26 can also be arranged, at least in sections, within the heating and cooling module block 6. The refrigerant lines 24, 25 can be hoses or pipes. The refrigerant lines 24, 25 are flanged 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.

[0082] The heat exchanger 26 is suitable for transferring heat Q from the refrigerant circuit 7 to a heat transfer medium circuit 27 and vice versa. A heat transfer medium M, for example 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 comprises a heat exchanger 28 arranged in the interior space 3 of the building 2. The heat exchanger 28 is a heat transfer medium-to-air heat exchanger. The heat exchanger 28 can be a heater or radiator. The heat transfer medium circuit 27 can be located at least partially within the heating and cooling module block 6.

[0083] A compressor or condenser 29 for compressing the refrigerant K is connected to the interfaces 14, 16. The compressor 29 is located entirely outside the heating and cooling module block 6. As previously mentioned, however, 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 comprise compressor blades or a piston.

[0084] The functionality of the heating and cooling system 1 in heating mode is explained below. The heating and cooling system 1 functions as a heat pump, in particular as an air-to-water heat pump. A suitable combination of the heat exchangers 22, 26, 28, for example, by using two refrigerant-to-liquid heat exchangers, can be used to create a water-to-water heat pump, or an air-to-air heat pump can be created by combining two refrigerant-to-air heat exchangers.

[0085] A "heat pump" is understood here to be a machine which, by expending technical work, absorbs thermal energy from a reservoir with a lower temperature, in this case the environment 5, and transfers it - together with the drive energy - as useful heat to a system to be heated with a higher temperature, in this case the interior 3 of the building 2.

[0086] The heat exchanger 22 absorbs heat Q from the environment 5. The heat exchanger 22 functions as an evaporator to at least partially evaporate the refrigerant K. The refrigerant K absorbs the heat Q. The refrigerant K is cold, has a low pressure, and is at least partially gaseous. This refrigerant K is fed to the compressor 29 via the refrigerant lines 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 gaseous.

[0087] The refrigerant K is then fed to the heat exchanger 26 via the refrigerant lines 15, 24. The heat exchanger 26 acts 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 warm.

[0088] The refrigerant K is thus fed via the refrigerant lines 8, 25 to the throttle valve

[0089] 11, where the pressure is reduced. Downstream of the throttle valve 11, the refrigerant K is liquid, has a low pressure, and is very cold.

[0090] The refrigerant K is fed back to the heat exchanger 22 via the refrigerant lines 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 via the heat exchanger 28 to heat it. To cool the interior 3, the process explained above can be reversed. The heating and cooling system 1 is then in cooling mode.

[0092] Fig. 2 shows a schematic sectional view of an embodiment of a heating and cooling module block 6A as mentioned above.

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

[0094] The sectional view according to Fig. 2 runs perpendicular to channels or lines 32, 33, 34, 35 that are led through the heating and cooling module block 6A. The lines 32, 33, 34, 35 can be part of the refrigerant circuit 7 and / or the heat transfer medium circuit 27. For example, the lines 32, 33, 34, 35 can be the previously mentioned refrigerant lines 8, 12, 15, 18, 20, 21, 24, 25 or other components of the refrigerant circuit 7 or the heat transfer medium circuit 27. The lines 32, 33, 34, 35 can be circular in cross-section. However, this is not absolutely necessary. For example, the lines 32, 33, 34, 35 can also be rectangular, in particular square, in cross-section. Each line 32, 33, 34, 35 has an inner wall or wall 36, 37, 38, 39 enclosing or surrounding the respective line 32, 33, 34, 35.In other words, each line 32, 33, 34, 35 is separated from a material 40 from which the heating and cooling module block 6A is made by its respective wall 36, 37, 38, 39. The walls 36, 37, 38, 39 thus enclose the lines 32, 33, 34, 35.

[0095] The refrigerant K and / or the heat transfer medium M circulates through the lines 32, 33, 34, 35. For example, the refrigerant K can circulate through all lines 32, 33, 34, 35, the heat transfer medium M can circulate through all lines, or the refrigerant K can circulate through some lines 32, 33, 34, 35 and the heat transfer medium M can circulate through other lines 32, 33, 34, 35.

[0096] Lines 32, 33, 34, and 35 are integrated into the heating and cooling module block 6A. "Integrated" means that lines 32, 33, 34, and 35 are directly inserted or incorporated into the material 40 of the heating and cooling module block 6A. Material 40 can also be referred to as the material or the heating and cooling module block material.

[0097] The "incorporation" or "incorporation" of the lines 32, 33, 34, 35 into the material 40 can be achieved, for example, by drilling, milling, and / or eroding. Additive or generative manufacturing processes, particularly 3D printing, can also be used. "Integrated" can also mean that the lines 32, 33, 34, 35 are completely surrounded by the material 40. However, this is not mandatory.

[0098] "Integrated" also means that the refrigerant K and / or the heat transfer medium M come into direct contact with the material 40. However, this does not preclude the possibility that the lines 32, 33, 34, 35 are coated on the inside of their walls 36, 37, 38, 39, for example, to prevent or impede corrosion.

[0099] As previously mentioned, 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 metallic materials can also be used. Furthermore, the heating and cooling module block 6A can also be made of a plastic material. Ceramic materials can also be used as material 40.

[0100] The heating and cooling module block 6A is a one-piece component, in particular a one-piece component. The heating and cooling module block 6A can have a first section 41, through which the lines 32, 33 run, and a second section 42, through which the lines 34, 35 run. The number of sections 41, 42 is arbitrary. The sections 41, 42 are connected to one another in one piece, in particular a one-piece component, and together form the heating and cooling module block 6A.

[0101] The first section 41 has a first cross-sectional area 43, which is shown hatched. The second section 42 correspondingly has a second cross-sectional area 44, which is also shown hatched. 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 desired cross-sectional geometry.

[0102] For example, the first section 41 has a width b41 when viewed along the x-direction x. Accordingly, the second section 42 has a width b42 when viewed along the x-direction x. The width b41 is smaller than the width b42. Heat Q is transferred between the lines 32, 33 and between the lines 34, 35. Because the first cross-sectional area 43, through which the lines 32, 33 run, is smaller than the second cross-sectional area 44, through which the lines 34, 35 run, the transfer of heat Q between the lines 32, 33 is reduced compared to the transfer of heat Q between the lines 34, 35. This results in more heat Q being transferred per unit of time between the lines 34, 35 than between the lines 32, 33.

[0103] Furthermore, the first section 41 cools down more strongly and / or more quickly than the second section 42 due to its smaller first cross-sectional area 43 compared to the second section 42. Since the first section 41 has a smaller width b41 than the second section 42, a transfer of heat Q from the second section 42 to the first section 41 is made more difficult, so that the first section 41 heats up less than the second section 42.

[0104] The heating and cooling module block 6A improves the efficiency of the heating and cooling system 1, particularly when operated as a heat pump. In particular, the heat distribution within the heating and cooling module block 6A is optimized. This prevents homogeneous heating of the heating and cooling module block 6A. Due to the smaller first cross-sectional area 43, only a small amount of the material 40 is present in the first section 41. This results in less heat Q being transferred from the line 32 to the line 33 or vice versa. The opposite is true for the second section 42 and the lines 34, 35.

[0105] Fig. 3 shows a schematic sectional view of another embodiment of a heating and cooling module block 6B as mentioned above. 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 a material 40 as mentioned above. Lines 32, 33, 34, 35 are guided through the material 40 and are enclosed or enclosed by walls 36, 37, 38, 39. For example, an exchange of heat Q should take place between the lines 32, 33 and the lines 34, 35. Preferably, no exchange of heat Q should take place between the two lines 32, 33 and the two lines 34, 35.

[0106] The heating and cooling module block 6B has a first section 41 and a second section 42, which together form the one-piece, in particular one-piece, heating and cooling module block 6B. Between the first section 41 and the second section 42, a cavity 45 is arranged, which is incorporated into the material 40. The cavity 45 is enclosed or delimited by a wall 46. The cavity 45 can run along the line 33 and / or along the line 34.

[0107] The cavity 45 can be created, for example, during the manufacture of the heating and cooling module block 6B using a salt core that is cast with the molten material 40 and rinsed out after the material 40 has solidified. Furthermore, the cavity 45 can also be incorporated into the heating and cooling module block 6B using abrasive manufacturing processes.

[0108] The cavity 45 is arranged between the lines 33, 34 as viewed along the y-direction y and prevents or impedes a transfer of heat Q from the first section 41 to the second section 42 or vice versa. The first section 41 and the second section 42 are only connected to each other by means of webs 47, 48, which are arranged on both sides of the cavity 45. The webs 47, 48 represent a cross-sectional constriction between the two sections 41, 42. A transfer of heat Q between the sections 41, 42 is only possible via the webs 47, 48. A first web

[0109] 47 and a second web 48 are provided.

[0110] 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 summary, the cavity 45 impedes the transfer of heat Q between the two sections 41, 42 and thus also between the lines 32, 33 and the lines 34, 35.

[0111] The heat transfer Q between line 34 and line 35 is intended to be improved compared to lines 32, 33. For this purpose, a heat-conducting element 49 is positioned between line 34 and line 35, as viewed along the y-direction y. The heat-conducting element 49 is encapsulated in or enclosed by the material 40. A wall 50 of the heating and cooling module block 6B encloses the heat-conducting element 49.

[0112] The heat-conducting element 49 is made of a material that has a higher thermal conductivity or a higher thermal conductivity coefficient than the material 40. This improves the transfer of heat Q between the lines 34, 35. The heat-conducting element 49 can be cast with the material 40 during the manufacture of the heating and cooling module block 6B.

[0113] In the second section 42, the transfer of heat Q is increased by an insert in the form of the heat-conducting element 49. Although the transfer of heat Q is not inhibited in the first section 41, it is poorer than in the second section 42 due to the absence of such a heat-conducting element 49. Additionally, the 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).

[0114] Fig. 4 shows a schematic sectional view of another embodiment of a heating and cooling module block 6C as mentioned above.

[0115] The heating and cooling module block 6C differs from the heating and cooling module block 6B only in that the cavity 45 is not filled with gas, but rather with a thermal insulation element 51. All statements regarding the heating and cooling module block 6B are applicable to the heating and cooling module block 6C, and vice versa.

[0116] The thermal insulation element 51 can, for example, be cast with the material 40 during the manufacture of the heating and cooling module block 6C. The thermal insulation element 51 is made of a material with poor thermal conductivity. For example, the thermal insulation element 51 can be made of glass wool or a ceramic material, in particular a foamed material.

[0117] Fig. 5 shows a schematic sectional view of another embodiment of a heating and cooling module block 6D as mentioned above.

[0118] The heating and cooling module block 6D is made of a material 40 as previously mentioned, through which lines 32, 33, 34, 35 are passed, which are delimited by walls 36, 37, 38, 39. The heating and cooling module block 6D has a first section 41 through which the lines 32, 33 run, and a second section 42 through which the lines 34, 35 run. The sections 41, 42 together form the heating and cooling module block 6D as a one-piece, in particular as a one-piece component. A thermal insulation element 51 as previously explained is arranged between the first section 41 and the second section 42 and is encapsulated by a wall 46 of the heating and cooling module block 6D. The thermal insulation element 51 thermally separates the sections 41, 42 from one another, so that a transfer of heat Q from the first section 41 to the second section 42 is not possible or at least difficult.The lines 32, 33 and the lines 34, 35 are separated from each other by means of the thermal insulation element 51.

[0119] A heat-conducting element 49, as previously explained, is placed between the lines 32, 33 and enclosed by a wall 50 of the heating and cooling module block 6D. A heat-conducting element 49, as previously explained, is placed between the lines 34, 35 and enclosed by a wall 50 of the heating and cooling module block 6D. The heat-conducting elements 49 facilitate the transfer of heat Q from the line 32 to the line 33 and vice versa, as well as the transfer of heat Q from the line 34 to the line 35 and vice versa.

[0120] During operation of the heating and cooling module block 6D, for example, a hot first refrigerant Kl can be conducted through line 32, which transfers heat Q to a first heat transfer medium Ml, which is conducted through line 33. In the orientation of Fig. 5, the first refrigerant Kl enters the heating and cooling module block 6D at the top at a first temperature TI and, in the orientation of Fig. 5, exits it again at the bottom at a second temperature T2. The first temperature TI is higher than the second temperature T2.

[0121] As the first refrigerant K1 flows through the heating and cooling module block 6D, it transfers heat Q to the first heat transfer medium Ml. The first heat transfer medium Ml enters the heating and cooling module block 6D at a third temperature T3 and exits it again at a 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.

[0122] A cold second heat transfer medium M2 can be conducted through line 34, transferring heat Q to a very cold second refrigerant K2, which is conducted through line 35. In the orientation shown in Fig. 5, the second heat transfer medium M2 enters the heating and cooling module block 6D at the top with a fifth temperature T5 and, in the orientation shown in Fig. 5, exits it at the bottom with a sixth temperature T6. The fifth temperature T5 is higher than the sixth temperature T6.

[0123] As 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 a seventh temperature T7 and exits it at an eighth temperature T8. 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.

[0124] At least in the different embodiments of the heating and cooling module block 6B, 6C, 6D, the transfer of heat Q can be partially promoted with the aid of the heat conducting element 49, so that individual regions of the heating and cooling module block 6B, 6C, 6D can be designed as heat exchangers.

[0125] In summary, on the one hand, thermal decoupling or inhibiting the transfer of heat Q is possible, for example with the aid of the different widths b41, b42, of the cavity 45 and / or the thermal insulation element 51, while on the other hand, targeted thermal coupling or promoting the transfer of heat Q is achievable, for example with the aid of the heat conducting element 49.

[0126] For thermal decoupling, a material having a lower thermal conductivity than material 40 can be used for the thermal insulation element 51. To promote the transfer of heat Q, the material thickness of the heating and cooling module block 6A, 6B, 6C, 6D can be partially increased. To increase the thermal conductivity, a material having a higher thermal conductivity than material 40 is used for the heat-conducting element 49. To inhibit the transfer of heat Q, the material thickness can be partially reduced, for example, in the area of ​​the webs 47, 48.

[0127] In the heating and cooling module block 6A, 6B, 6C, 6D, some areas are designed to promote the transfer of heat Q, while other areas prevent or at least hinder the transfer of heat Q. If no design measures, as previously mentioned, are taken, the heating and cooling module block 6A, 6B, 6C, 6D will heat up homogeneously over time and reach an undesirable temperature in certain areas. This temperature may be too low and / or too high.

[0128] In principle, as previously explained, at least two options are possible for improving or preventing the transfer of heat Q. Firstly, as explained with reference to the heating and cooling module block 6A, the shape can be changed. Secondly, components such as the heat-conducting element 49 and / or the heat-insulating element 51 can be added to the heating and cooling module block 6B, 6C, 6D.

[0129] When changing the shape, the approach is that with a material accumulation, for example in the area of ​​the second section 42 of the heating and cooling module block 6A, a greater transfer of heat Q takes place than with a material saving, such as in the area of ​​the first section 41 of the heating and cooling module block 6A. If a greater transfer of heat Q now takes place in certain areas of the heating and cooling module block 6A, then a greater material thickness is realized in these areas.

[0130] Conversely, if a lower heat transfer Q is to occur in another specific area, material is deliberately omitted and thus a lower material thickness is selected. The heating and cooling module block 6A is therefore no longer symmetrical in all planes, particularly with regard to its outer contour. In particular, the heating and cooling module block 6A has a different width b41, b42 over its entire length, at least in one area. This approach can be used if external factors, such as available installation space, do not represent a limiting factor.

[0131] The addition of elements in the form of the cavity 45, the heat-conducting element 49, and / or the thermal insulation element 51 takes into account the problem of external spatial limitations. The basic idea is to use elements in the form of the cavity 45, the heat-conducting element 49, and / or the thermal insulation element 51 that have a higher or lower thermal conductivity than the material 40, for example, aluminum.

[0132] For example, air contained in the cavity 45 is very well suited as an element with low thermal conductivity. Compared to aluminum, which has a thermal conductivity of approximately 160 W / mK, air has a thermal conductivity of approximately 0.0262 W / mK. If low thermal conductivity is desired in certain areas, the cavity 45 is created at this point so that it essentially serves as an insulator. As previously mentioned, this cavity 45 can be filled with a thermal insulation element 51 in the form of a foam or other insulator. The cavity 45 can be subsequently introduced into the material 40, for example, by etching, drilling, milling, or the like. The cavity 45 is particularly preferably introduced directly during a casting process, for example by placing a salt core in a die-casting mold and flushing it out again after the molten material 40 has solidified.

[0133] Various metallic and non-metallic materials with high thermal conductivity are suitable as heat-conducting elements 49. The ability of materials to dissipate heat Q depends not only on their thermal conductivity, but also on the density of the respective material. For inserts in the form of the heat-conducting element 49 and / or the thermal insulation element 51, their expansion upon temperature change after the molten material 40 has solidified must be taken into account. Furthermore, the melting temperature of the material used for the heat-conducting element 49 and / or the thermal insulation element 51 must not be lower than that of the material 40.

[0134] Compared to aluminum, which has a thermal conductivity of approximately 160 W / mK, copper has a thermal conductivity of approximately 400 W / mK, silicon carbide a thermal conductivity of approximately 490 W / mK, graphite a thermal conductivity of approximately 2000 W / mK, and diamond a thermal conductivity of over 2000 W / mK. All of the aforementioned materials can be used. The use of boron compounds is also possible.

[0135] Copper, whose melting point is approximately 1060 °C, is particularly preferred for the heat-conducting element 49. If high thermal conductivity is desired, an insert made of a material with higher thermal conductivity is inserted as the heat-conducting element 49, the volume of which is identical to that of the no longer present material 40. The insert is then inserted into the melt. The external dimensions of the heating and cooling module block 6B, 6C, 6D do not change, although the thermal conductivity is partially improved.

[0136] If heat transfer between the material 40 and the heat-conducting element 49 and / or the heat-insulating element 51 is desired, it must be ensured that particularly good contact is established between the heat-conducting element 49 and / or the heat-insulating element 51 and the material 40 during the melting process and / or the casting process. This can be achieved by a particularly rough surface of the heat-conducting element 49 and / or the heat-insulating element 51 to ensure good contact.

[0137] Furthermore, a contact-promoting layer can be introduced between the heat-conducting element 49 and / or the heat-insulating element 51 and the material 40. This can be achieved by applying a special surface coating to the heat-conducting element 49 and / or the heat-insulating element 51. Furthermore, it is possible to heat the heat-conducting element 49 and / or the heat-insulating element 51 to the temperature of the molten material 40 to improve contact.

[0138] Fig. 6 shows a schematic block diagram of an embodiment of a method for manufacturing the heating and cooling module block 6A, 6B, 6C, 6D.

[0139] In the method, the material 40 is melted in a step S1. In a step S2, the molten material 40 is cast such that the heating and cooling module block 6, 6A, 6B, 6C, 6D is manufactured, in particular, as a one-piece component, and such that the heat conduction within the first section 41 or within the second section 42 is better than the heat conduction between the first section 41 and the second section 42. Step S2 can be carried out using a casting mold, in particular using a die-casting mold. The aforementioned one-piece production is not absolutely necessary. The heating and cooling module block 6, 6A, 6B, 6C, 6D can also be manufactured in multiple parts.

[0140] During step S2, a cavity 45 as previously mentioned 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 then flushed out after the material 40 has solidified. Multiple cavities 45 can also be formed.

[0141] During step S2, alternatively or additionally, a heat insulation element 51 as explained above, which is made of a material having a lower thermal conductivity coefficient than the material 40, and / or a heat conduction element 49, which is made of a material having a higher thermal conductivity coefficient than the material 40, can be cast with the molten material 40.

[0142] Although the present invention has been described using exemplary embodiments, it can be modified in many ways.
