Description

Heating circuit and degassing device DESCRIPTION Technical area

[0001] The present invention relates to a heating circuit for supplying a heat exchanger with an energy transport medium and a degassing device for degassing a heating circuit. Background of the invention

[0002] Heating circuits are known from the prior art that transport heat and / or cold energy to a heat exchanger via an energy transport medium flowing therein, for example, to heat and / or cool a room in a building. An example of this is a well-known heating system that transports a temperature-controlled energy transport medium, usually water, via a network of pipes to heat exchangers designed as radiators or underfloor heating.

[0003] Such heating circuits typically include degassing devices, through which gas contained in the heating circuit can be removed. This not only increases the efficiency of energy transport but can also be relevant to safety under certain circumstances. The latter is particularly the case if there is a risk of the energy transport medium being contaminated by working fluids from other systems, such as hydrocarbons from a heat pump circuit that is coupled to the heating circuit via a heat exchanger (e.g., evaporator or condenser).

[0004] For example, DE 10 2020 103 743 A1 discloses a heating circuit comprising a check valve and a degassing device as safety components, via which gas flowing in the heating circuit together with the energy transport medium can be removed. The degassing device of DE 10 2020 103 743 A1 has, as an additional safety component, a closing device with a float, which is designed to prevent the flow of the energy transport medium through the degassing device and thus also the flow in the entire heating circuit, depending on the amount of gas contained in the heating circuit, in order not only to ensure safety but also to protect components of the heating circuit from damage.

[0005] As a safety-relevant component, the degassing device and in particular its closing device must function reliably, which requires regular maintenance but also a long service life of the respective components. The former is particularly complex in the case of the degassing device shown in DE 10 2020 103 743 A1. Summary

[0006] An object of the present invention is therefore to provide a heating circuit which is improved compared to the prior art and which has a reliable and long-lasting possibility for degassing the same.

[0007] To achieve this object, a heating circuit according to claim 1 and a degassing device according to claim 15 are provided.

[0008] The respective dependent claims relate to preferred embodiments which may be provided individually or in combination.

[0009] According to a first aspect of the invention, a heating circuit is provided for supplying at least one heat exchanger configured for cooling and / or heating a room of a building with an energy transport medium flowing through the heating circuit. For this purpose, the heating circuit comprises at least one heat exchanger configured to temperature-control the energy transport medium flowing in the heating circuit, in particular via a heat exchange with a working medium of a heat pump circuit, and a degassing device configured to degas the heating circuit. The degassing device comprises a container which encloses an interior space and which has an inlet for introducing the energy transport medium into the interior space and an outlet for discharging the energy transport medium from the interior space and which is formed from at least a first and a second container component.The first and the second container components can be detachably connected to one another via respective connecting sections adapted to one another in order to form at least part of the interior space, wherein a reinforcing element is fastened at least to the connecting section of the first or to the connecting section of the second container component.

[0010] The chosen umbrella term "heating circuit" is intended to also encompass the function of a cooling circuit. Thus, the term "heating circuit" should not be understood as being limited to the case where the energy transport medium is heated as it flows through the heat exchanger, but should also encompass the possibility of the energy transport medium being cooled by the heat exchanger. Thus, the heating circuit according to the invention can be operated in a heating and / or cooling mode.

[0011] In many applications, the energy transport medium flowing in the heating circuit, usually water, can be contaminated with gases, which can be not only air but also other substances.

[0012] Heat pumps are increasingly being used in heating and cooling systems for buildings, where a heat pump circuit is used to control the temperature of the energy transport medium of the heating circuit. The heat exchanger can be used to switch between a Heat and / or cooling energy is transferred between the working medium of the heat pump circuit and the energy transport medium of the heating circuit. Common working media in heat pump circuits are refrigerants with a boiling point of -60°C to -15°C at atmospheric pressure, such as the flammable hydrocarbon propane.

[0013] In the event of a gas leak at the heat exchanger, this can lead to contamination of the energy transport medium with gaseous refrigerant of the heat pump circuit, which, in addition to a loss of efficiency in the energy transport in the heating circuit, also represents a safety risk during the operation of the same.

[0014] The degassing device ensures that the working medium that has passed through does not spread in the heating circuit, but can be collected and discharged by the degassing device.

[0015] The degassing device is preferably designed such that gas flowing into the interior space through the inlet with the energy transport medium collects in a partial area of ​​said interior space (=collection area) and is not directed further to the outlet to prevent the gas from spreading in the heating circuit. In particular, the inlet is arranged above the outlet with respect to the Earth's gravitational field.

[0016] Preferably, the degassing device comprises a vent arranged on the container in the collection area for the gas, via which the gas collected in the collection area can be removed from the degassing device and thus from the heating circuit.

[0017] With regard to operational safety, the degassing device preferably further comprises a closing device arranged in the interior, which, from a certain degree of contamination, i.e. a certain amount of gas in the heating circuit or in the interior of the container, prevents a flow of the energy transport medium in the heating circuit and thus also a spreading of the gas therein.

[0018] The design of the container with two detachably connectable container components allows easy access to the interior of the degassing device, which, among other things, significantly simplifies assembly and / or maintenance. This allows components in the interior, such as those of the closing device, to be replaced quickly and without major assembly or disassembly effort.

[0019] The connecting sections of the container components are to be understood as connecting sections adapted to one another, which can be brought into a force-locking and / or form-locking engagement in order to detachably connect the two container components to one another, for example in the form of a bayonet coupling.

[0020] The connecting sections are preferably designed in such a way that the detachable connection requires no additional connecting or clamping means. In other words, the connecting section of one of the two container components can be inserted into the connecting section of the other container component, preferably manually and without tools, in a form-fitting and / or force-fitting manner, thereby directly establishing a connection.

[0021] Disconnecting the container components allows access to the interior space enclosed by the container, which can then be closed again by connecting the container components.

[0022] In order to ensure a tight connection between the two container components for the gas and the energy transport medium, at least one of the two connecting sections is provided with a reinforcing element which reinforces the respective connecting section so that a tight closure of the interior is ensured even after repeated separation and re-establishment of the connection between the two container components.

[0023] Furthermore, the reinforcing element can reduce mechanical and / or thermal stress on the connecting sections during operation of the heating circuit as well as during opening and closing of the interior, thereby reducing wear and material fatigue of the connecting sections ensuring the connection.

[0024] Furthermore, the introduction of the reinforcement element can reduce thermally induced material expansion in the area of ​​the connecting sections, which could potentially have a negative impact on their interaction. Material expansion can lead to geometric changes, which – depending on the severity – can result in a loss of the force-locking and / or positive connection or even cause wedging, making the connecting sections irreparable. Such disadvantages can be prevented by using the reinforcement element, which is designed in particular to compensate for or suppress longitudinal expansion in the axial direction of the container.

[0025] Furthermore, the reinforcing element provides the internal tension required for tightly closing the container, especially when the two container components are connected purely "manually", so that the reinforcing element preferably corresponds to a pre-tensioning element which causes a contact force in a contact area of ​​the two connecting sections.

[0026] The above effects provide a degassing device that ensures quick and easy access to the interior and is nevertheless characterized by a long service life without loss of sealing in the connection area of ​​the container components.

[0027] Preferably, one or both connecting sections are designed as integral components of the respective container component, in other words, as a single piece. This reduces the number of cuts and joints, as the connecting sections do not have to be attached to the respective container component during production, but are an integral part.

[0028] Likewise, inlet and / or outlet can preferably be integrated as integral parts of the Container components can be designed. The inlet and outlet can be designed as components of the same container component or as components of different container components.

[0029] Further preferably, a reinforcing element is attached to each of the two connecting sections.

[0030] In a preferred embodiment, in a connected state of the two Container components, the reinforcement element is arranged in the interior of the container. In other words, the reinforcement element is attached to one of the connecting sections in such a way that it can come into contact with the energy transport medium located in the interior.

[0031] In this way, the reinforcement in the area of ​​the main thermal load is achieved by the tempered energy transport medium, whereby thermally induced expansions in particular can be particularly well compensated by the reinforcement element.

[0032] In a preferred embodiment, the degassing device comprises a sealing element which, in a connected state of the two container components, is arranged between the connecting section of the first and the connecting section of the second container component of the degassing device. In particular, this is an O-ring.

[0033] This provides additional sealing of the interior against the environment of the degassing device

[0034] In a preferred embodiment, the reinforcing element and the two Connecting sections of the container components of the degassing device are adapted to one another in such a way that the reinforcing element, in the connected state, exerts a clamping force on the connecting section of the first and / or the second container component, so that the sealing element is clamped between the two connecting sections

[0035] This utilizes the previously described function of the reinforcement element as a preload element to clamp the sealing element. In this case, the sealing element is located in the contact area and is clamped between the surfaces of the connecting sections, further increasing the sealing effect.

[0036] In a preferred embodiment of the heating circuit, the reinforcing element of the degassing device is arranged such that a section of the Reinforcing element in the connected state relative to an axial longitudinal direction of the container is at the level of the sealing element

[0037] This allows the clamping force of the reinforcing element described above to act directly on the sealing element in order to achieve the optimal sealing effect.

[0038] In a preferred embodiment, a material of the reinforcing element of the Degassing device different from a material of the first and / or the second container component, in particular of their connecting sections.

[0039] This allows the selection of particularly suitable materials for sealing, especially for the connecting sections, whose "missing" properties, for example with regard to their elastic behavior, can be compensated for by the reinforcing element made of a different material.

[0040] In a preferred embodiment, the first and / or the second container component of the degassing device, in particular their connecting sections, are made of a plastic material or of a composite material comprising plastic, and / or the reinforcing element of the degassing device is made of a metallic material or of a plastic material whose coefficient of thermal expansion is lower than that of the plastic material / composite material of the container components.

[0041] The composite material is preferably fiber-reinforced plastic, in particular glass-fiber-reinforced plastic.

[0042] Plastic offers the advantage of simple and cost-effective production with few work steps, especially when the inlet and outlet ports and connecting sections are designed as integral components of the respective container components. Furthermore, plastic is particularly lightweight and provides good sealing in the event of contact, for example, compared to purely metallic contacts.

[0043] The reinforcement element, which is particularly made of a metallic material, advantageously compensates for the adverse properties of the plastic. These include, for example, a loss of strength and the associated deterioration of elastic properties due to the changing temperature loads caused by the energy transport medium flowing through the interior. Furthermore, the reinforcement element also reduces or compensates for temperature-induced longitudinal expansion of the plastic, particularly in the axial direction of the container, so that gap and fit dimensions in the area of ​​the connecting sections remain as constant as possible and do not lead to a deterioration of the effective engagement or even to wedging of the two connecting sections.

[0044] Under certain circumstances, the plastics may even creep, which has a negative impact on the tension of the sealing element. This is advantageous This is prevented by the preferably metallic reinforcement element, which strengthens the plastic and reduces internal stresses and thus reduces creep behavior

[0045] In this way, the advantages of a durable material via the reinforcement element are combined with the advantages of the container components made of plastic, so that a lightweight, cost-effective container is provided, the components of which can be connected to one another in a leak-proof yet detachable manner over a long period of time.

[0046] In a preferred embodiment, the first and second container components of the degassing device are designed such that, in the connected state, an outer circumferential surface of the connecting section of the first container component is at least partially enclosed by the connecting section of the second container component

[0047] In a preferred embodiment, the reinforcing element of the degassing device is attached to an inner peripheral surface of the connecting portion of the first container component

[0048] Preferably, the reinforcing element is designed as a reinforcing sleeve

[0049] As a result, the reinforcement element can advantageously be used as a tensioning element with a radially outward-acting clamping force.

[0050] In a preferred embodiment, the reinforcing element of the degassing device is attached to the connecting section of the first container component via a press fit

[0051] This enables a comparatively simple attachment of the reinforcement element without additives.

[0052] In a preferred embodiment, a portion of the inner peripheral surface of the connecting portion of the first container component of the degassing device is shielded by the reinforcing element from the energy transport medium located in the interior

[0053] This allows the direct contact or a surface of the connecting section wetted by the energy transport medium to be reduced, which in turn has a positive effect on the aging effects of the material, especially in a plastic version.

[0054] In a preferred embodiment, the connecting portions of the first and second container components together form a bayonet coupling.

[0055] A bayonet coupling is a detachable mechanical connection between two components that is created by inserting them into one another and twisting them, without the need for any additional connecting or clamping devices.

[0056] This enables a particularly easy to produce and detach connection between the two container components, which usually allows manual production / detachment without tools

[0057] Preferably, a wall thickness of the reinforcing element of the degassing device is less than a wall thickness of the connecting section of the first and / or the second container component, in particular if the reinforcing element is made of the metallic material

[0058] In a preferred embodiment, the degassing device comprises a closing device which is designed to prevent a flow of the energy transport medium from the inlet to the outlet of the degassing device depending on a quantity of gas contained in the heating circuit.

[0059] This allows for an immediate stop of the flow in the event of a critical amount of gas in the heating circuit or inside the tank, preventing this amount of gas from spreading through the heating circuit. Such a quantity could potentially be harmful to the heating circuit and, in the case of a flammable gas, also pose a safety risk.

[0060] The design of the detachably connectable container components enables the aforementioned easy access to the interior of the container, via which maintenance or replacement work on the closing device can be carried out quickly, for example if individual components of the closing device become jammed.

[0061] In a preferred embodiment, the closing device comprises a float movably mounted in the interior of the container (see also Fig. 3A).

[0062] This allows a comparatively simple implementation of the closing device and the mechanics underlying it.

[0063] Preferably, the bearing is carried out via a guide element arranged in the interior, for example in the form of a guide tube.

[0064] The degassing device is preferably arranged downstream of the heat exchanger in the heating circuit, in particular directly downstream of the heat exchanger, with respect to the flow direction of the energy transport medium. This allows the gas to be prevented from spreading in the heating circuit at a particularly early stage.

[0065] According to a second aspect of the invention, a degassing device is provided which is designed for degassing a heating circuit through which an energy transport medium flows, in particular a heating circuit according to an embodiment of the first aspect of the invention. The degassing device comprises a container which encloses an interior space and which has an inlet for introducing the energy transport medium into the interior space and an outlet for discharging the energy transport medium from the interior space. and which is formed from at least a first and a second container component. The first and the second container component are detachably connectable to one another via respective, mutually adapted connecting sections in order to form at least a part of the interior space, wherein a reinforcing element is attached at least to the connecting section of the first or to the connecting section of the second container component.

[0066] By providing the degassing device separately, an existing heating circuit can be easily developed into the heating circuit according to the first aspect of the invention and thus offers all the advantages already described above in this context.

[0067] The degassing device according to the second aspect of the invention can be designed according to any embodiment described in the course of the above description of the heating circuit. These embodiments will not be repeated here.

[0068] Further aspects and their advantages as well as more specific embodiments of the aforementioned aspects and embodiments are described below with the aid of the drawings shown in the attached figures.

[0070] Fig. 2 shows a side view of an embodiment of the degassing device according to the invention.

[0071] Fig. 3A shows a sectional view of the degassing device from Fig. 2.

[0072] Fig. 3B shows an enlarged section of the sectional view from Fig. 3A in an area of ​​connecting sections of the two container components.

[0073] It is emphasized that the present invention is in no way limited to the exemplary embodiments described below and their embodiment features. The invention further comprises modifications of the aforementioned exemplary embodiments, in particular those which result from modifications and / or combinations of individual or multiple features of the described exemplary embodiments within the scope of protection of the independent claims. Detailed character description

[0074] Fig. 1 shows a schematic overview of an embodiment of the heating circuit 1000 according to the invention.

[0075] The heating circuit 1000 comprises a condenser 1 Heat exchanger in which heat Q from a flowing in a heat pump circuit 2000 Working medium can be transferred to an energy transport medium flowing in the heating circuit 1000. Flow directions of the respective media are shown by arrows in Fig. 1. If the heating circuit is to be used alternatively for cooling, it would be coupled to the evaporator 2001 of the heat pump circuit 2000 shown in Fig. 1.

[0076] In the condenser 1, the working medium coming from the compressor 2002 is liquefied before it is then fed to an evaporator 2001 of the heat pump circuit 2000 via an expansion valve 2003.

[0077] Furthermore, the heating circuit 1000 comprises a degassing device 2 connected downstream of the condenser 1 - with respect to the flow direction of the energy transport medium - and a heating circuit pump 4 connected upstream of the condenser 1 as well as a check valve 3.

[0078] Starting from the degassing device 2, the energy transport medium heated by the condenser 1 is transported via lines 5 to heat exchangers arranged in rooms (not shown). The return flow from the heat exchangers ends again at the heating circuit pump 4.

[0079] The degassing device 2 is designed to prevent the spread of gas in the heating circuit 1000, which can flow through the lines 5 together with the energy transport medium.

[0080] The degassing device 2 comprises a container 20 which encloses an interior space (see, for example, Fig. 3A) into which the energy transport medium (and thus also the unwanted gas) is introduced via an inlet 23 and from which further transport to the heat exchangers takes place via the outlet 24. The unwanted gas can collect in a section of the interior space, here in the upper section, and be removed from the heating circuit 1000 via a vent 25.

[0081] The container 20 is formed from an upper container component 21 and a lower container component 22, which are detachably connected to one another via matching connecting sections 210, 220. Releasing the connection allows access to the interior 26.

[0082] A reinforcing element reinforcing the respective connecting section 210, 220 is attached to at least one of the two connecting sections 210, 220 (not shown in Fig. 1, but see, for example, Fig. 3B).

[0083] The reinforcing element reduces mechanical and / or thermal stress on the two connecting sections 210, 220 during operation of the heating circuit 1000 as well as during opening and closing of the interior, thereby reducing wear and material fatigue of the connecting sections 210, 220 ensuring the connection.

[0084] As a result, the degassing device 2 allows quick and easy access to the interior, for example for assembly or maintenance work, and is nevertheless characterized by a long service life without loss of sealing in the connection area.

[0085] Fig. 2 shows a side view of an embodiment of the degassing device 2 according to the invention.

[0086] The degassing device 2 comprises a container 20 which encloses an interior space 26 (see Fig. 3A) into which the energy transport medium (and thus also the unwanted gas) is introduced via an inlet 23 and from which the degassed energy transport medium is further transported via the outlet 24. The unwanted gas can collect in an upper section of the interior space 26 (= collection area) and be removed from the degassing device 2 via a vent 25.

[0087] The container 20 is formed from an upper container component 21 and a lower container component 22, both of which have a substantially cup-like shape with a cylindrical central portion.

[0088] The inlet 23 is formed as part of the upper container component 21 and the outlet 24 is formed as part of the lower container component 22.

[0089] Both container components 21, 22 are preferably (and not restrictively) made of plastic or of a composite material comprising plastic, which allows for simple and cost-effective production. Furthermore, this also allows for a weight reduction compared to other materials.

[0090] The two container components 21, 22 are detachably connected to one another via matching connecting sections 210, 220. Releasing the connection allows access to the interior 26.

[0091] The connecting section 220 of the lower container component 22 at least partially encloses an outer peripheral surface of the connecting section 210 of the upper container component 21. The two connecting sections 210, 220 form a bayonet coupling, i.e., a detachable mechanical connection between two components, which is established by inserting them into one another and twisting them together, without the need for any additional connecting or clamping means. For this purpose, the two container components 21, 22 are inserted into one another according to the arrow markings and then twisted.

[0092] The connecting sections 210, 220 as well as the inlet 23 and the outlet 24 are designed as integral components of the respective container components 21, 22. Thus, the container components 21, 22 can preferably be manufactured directly in one operation, for example in the case of a design made of plastic or said composite material by a Injection molding process. The two container components 21, 22, including their connecting sections 220, 220, are preferably made of glass fiber reinforced plastic.

[0093] Fig. 3A shows a sectional view of the degassing device 2 from Fig. 2, along the sectional plane AA shown in Fig. 2.

[0094] A repeated description of the components of the degassing device already shown in Fig. 2 will be omitted at this point.

[0095] As can be seen from Fig. 3A, the container 20 formed from the two container components 21, 22 encloses the interior space 26, through which the energy transport medium can flow from the inlet 23 to the outlet 24. The unwanted gas collects in the collection area below the vent 25.

[0096] An O-ring 28 is arranged as a sealing element between the connecting sections 210, 220 of the two container components 21, 22, which additionally seals the connection to reliably prevent gas and / or energy transport medium from escaping from the interior space 26. An enlarged view of the connecting area is shown in section X in Fig. 3B.

[0097] Furthermore, a closing device 27 is arranged in the interior space 26, via which a flow of the energy transport medium from the inlet 23 to the outlet 24 of the degassing device 2 is prevented depending on a quantity of gas contained in the heating circuit 1000 or a quantity of gas accumulated in the interior space 26.

[0098] For this purpose, the closing device 27 comprises the float 270 which is movably mounted in a float guide 271 and which normally floats in the upper region of the interior space 26 due to the buoyancy in the energy transport medium.

[0099] As the gas quantity in the upper region of the interior space 26 increases, the float 270 is ultimately pushed downward or moves downward along the float guide 271 and comes into contact with a float seat 240 at the outlet 24. This blocks the outlet 24 and prevents any flow through the outlet 24, both of gas and energy transport medium.

[0100] The cylindrically shaped float guide 271 is fitted into the interior space 26 and has a plurality of through-openings 271b distributed over the circumference, through which the separation of bubbles in the energy transport medium is improved.

[0101] The float 270 itself has guide webs at its upper end, which keep the float 270 straight during relative movements within the float guide 271 and prevent jamming. Furthermore, the float 270 is hollow to provide the necessary buoyancy and has a stabilizing weight 270b located in the hollow space 270a, which ensures that the float 270 floats stably on the energy transport medium and also sinks straight.

[0102] Fig. 3B shows an enlarged section of the sectional view from Fig. 3A in a region X of the connecting sections 210, 220 of the two container components 21, 22.

[0103] As already described, the connecting sections 210, 220 are together designed as a bayonet coupling, in which, by inserting and twisting, one or more outer peripheral tabs 210a of the connecting section 210 of the upper container component 21 are brought into at least positive engagement with a corresponding inner peripheral groove 220a of the connecting section 220 of the lower container component 22. Furthermore, the O-ring 28 is arranged as a sealing element between the peripheral surfaces of the connecting sections 210, 220.

[0104] A reinforcing element embodied as a reinforcing sleeve 29 is attached, preferably via a press fit, to an inner circumferential surface of the connecting portion 210 of the upper container component 21. The position of the reinforcing sleeve 29 in an axial longitudinal direction of the container 20 is defined by the tab of the reinforcing sleeve 29 in contact with an end face of the connecting portion 210.

[0105] The reinforcing sleeve 29 is preferably made of a metallic material and reinforces the connecting section 210 made of plastic in order to ensure sufficient tightness of the container 20 even over a longer period of time.

[0106] The reinforcement sleeve 29 thus compensates for the material fatigue occurring at the connecting section 210 and, in particular, always ensures a sufficient clamping force acting on the O-ring 28, which would be lost over time without the reinforcement sleeve 29, for example, due to material fatigue. The reinforcement sleeve 29 is preferably pressed into the connecting section 210 under prestress and acts as a prestressing element.

[0107] For this purpose, the reinforcement sleeve 29 is preferably arranged such that at least a portion of the reinforcement sleeve 29, in the connected state, is located at the level of the O-ring 28 relative to the axial longitudinal direction of the container 20. In other words, a radially outwardly directed clamping force of the pressed-in reinforcement sleeve 29 acts directly on the O-ring 28 via the connecting portion 210, thus reinforcing the sealing effect of the interior space 26 with respect to the environment.
