Description

TECHNICAL FIELD

[0001] The invention relates to a method for securing a heating device during transport. Also, the invention relates to a method for manufacturing a foldable element for securing a heating device during transport and to a usage of a foldable element for securing a heating device during transport. The invention further relates to a heating device comprising a foldable element for securing the heating device during transport.BACKGROUND

[0002] A heating device, such as a heat pump for example, typically comprises a vibration sensitive element, such as a compressor and / or a part of a refrigerant circuit, and a substantially rigid structure, such as a frame. Vibration sensitive elements are sensitive components. During transport, the heating device is subjected to external events, so securing the heating device during transport is required. Nowadays, several solutions exist, for exemple shown in document CN 208 238 062 U, which are, however, often difficult to apply, resource-intensive in production and / or expensive.TECHNICAL PROBLEM

[0003] Regarding a heat pump, for example, a heat pump typically comprises a compressor as an example for a vibration sensitive element. A compressor used in a heat pump is a sensitive component, in particular as the compressor comprises moving parts. The moving parts are used to compress fluids for example, so the moving parts need to be carefully dimensioned and positioned. To limit friction and improve the service life of the compressor, oil is used as lubricant.

[0004] The compressor has at least one motor that rotates one of the elements that allow the compressor to work. The entire compressor environment is pressurized. The heat pump is a heavy, bulky and vulnerable object, making its transportation risky.

[0005] During all transport phases from the place of manufacture to the place of installation, the heat pump is subjected to external events, such as accelerations, shocks, tilting, vibrations etc. Each time the heat pump is subjected to such an external event, this may impact and weaken the compressor within the heat pump, reducing its quality and life span. A further problem is that when there is a positive or negative acceleration of the heat pump, the compressor can initiate a movement due to its fixing on anti-vibrating pads and due to the degree of relative freedom of movement offered by this type of solution. This creates a high inertia of the compressor and thus creates more energy and stress on the fixing elements by means of which the anti-vibration pads are fixed on the housing of the heat pump, or on the support plate or on the heat pump panels. As a result, the compressor mounting parts can also be damaged, leading to reliability problems for the heat pump. Some of these external events are, for example, described and tested in the standards associated with transport, such as the following normative texts ASTM D880-92, ASTM D999, ASTM D4728, ASTM D642, ASTM D6055-96 / D880-92 / D6179-07.

[0006] The heat pump may be placed on flexible anti-vibration pads. The purpose of these pads is to reduce the transmission of vibrations from the compressor to the rest of the heat pump when the heat pump is installed and the compressor is running. It enables to reduce the noise generated by the heat pump due to the vibration of the compressor. Furthermore, it also improves the lifetime of the parts that are connected to the compressor, such as piping, by reducing accumulated damage due to the vibration that might otherwise result in leakage. However, during the transport phase, this type of pads accentuates the shocks that the compressor and its fastening elements undergoes because it provides the compressor with more freedom of movement and inertia before a sudden stop.

[0007] A damage in the compressor area can occur during the transport of the heat pump. In particular, one or more anti-vibration pads can bent or be broken resulting in that the compressor is not arranged horizontally during heat pump operation. The compressor cannot be reattached horizontally as these structural parts are not replaceable. When the compressor is no longer arranged horizontally, it can no longer operate efficiently and / or reliably.

[0008] Furthermore, if the compressor has moved, it also means that the tubing of the associated refrigeration circuit has been deformed and is therefore at risk of leaking or a premature end of life. In the case of flammable refrigerant, this means that a damage of the support of the compressor can cause flammable fluid, in particular propane, to leak out of the compressor and thus pose a risk of product explosion.

[0009] In order to limit the impact of the anti-vibration pads under the compressor during the transport phases, several solutions exist to fixate or stabilize the compressor for transport that needs to be removed when the product will be installed and before initial operation. For example, this may be done with the use of shims or flexible studs between the compressor and its support integrated before the transport. Another solution is to install additional screws or to securely fix the compressor for transport.

[0010] All these solutions, however, have certain drawbacks in that the arrangement and the removal of such solutions from the compressor may be time-consuming, in that the fixing element may cause wear or damage to the heat pump, in that production and transportation of such solutions may be resource-efficient, and / or in that recyclability of such solutions may be at least limited. Hence, there is need for improvement. It is therefore an object of the present disclosure to overcome at least part of these drawbacks.SUMMARY

[0011] At least part of the technical problems and the drawbacks as outlined above in detail are overcome based on the present disclosure.

[0012] Insofar, according to a first aspect of the invention defined in claim 1, there is disclosed a method for securing a heating device, such as a heat pump, during transport. The heating device comprises a substantially rigid structure, such as a frame, and a vibration sensitive element, such as a compressor and / or a part of a refrigerant circuit. A part of a refrigerant circuit may be one or more parts, or all parts of the refrigerant circuit. The vibration sensitive element is attached to the substantially rigid structure with a predetermined amount of movability in at least a first direction with respect to the substantially rigid structure. The first direction is in a plane that is horizontal when the heating device is in a use-position, for example when the heating device is installed at an operation side. The method comprises folding a foldable element to form a three-dimensional shape. The foldable element is movable between a planar configuration and a folded configuration. The foldable element comprises a planar portion, wherein the planar portion comprises a first edge section and a second edge section. Additionally, the planar portion is connected to a first side panel of the folded foldable element and to a second side panel of the folded foldable element. For example, in case the folded foldable element may be of a box shape, the first and second side panels may represent side panels of the box-shaped folded foldable element. The method further comprises positioning the folded foldable element at least partially in the first direction between the vibration sensitive element and the substantially rigid structure so that the first edge section is in contact with the substantially rigid structure, the second edge section is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction. Additionally or alternatively, the positioning may be made so that the first side panel has a normal vector substantially parallel to the first direction and is in contact with the substantially rigid structure, the second side panel has a normal vector substantially parallel to the first direction and is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction.

[0013] The folded foldable element is advantageous, in that it may be positioned and removed comparatively fast, for example in comparison to a fixing by using screws. Moreover, no tools may be required for the positioning and the removal of the folded foldable element. Further, as the folded foldable element is a folded part and may thus be transported in an unfolded, i.e. planar configuration, a reduction of the dimension of the part is achieved when it needs to be transported, for example between a manufacturing location of the foldable element and an installation location at which the foldable element is positioned inside the heating device's casing, and / or between the installation location and a recycling plant for disposing the folded element. Further, such foldable element allows for more compacity during the whole supply chain comprising transport and stocking, and thus a reduction of total CO2 emission for the transport is achieved, because more foldable elements in an unfolded, i.e. planar configuration can be loaded in a same transportation vehicle. Finally, after the removal of the folded foldable element, the element may be unfolded back to a planar configuration and / or serve a further purpose during the installation of the heat pump, such as being used to protect the floor and / or to offer a clean surface for the installer to use during the installation.

[0014] Moreover, according to at least some examples, the positioning may further comprise positioning the folded foldable element at least partially in a second direction between the vibration sensitive element and the substantially rigid structure, wherein the second direction is in the plane and is non-parallel to the first direction.

[0015] In doing so, movement of the vibration sensitive element may be blocked more efficiently and the vibration sensitive element may be held in position more reliably. Particularly, the folded foldable element may hold a substantial section of the circumference or perimeter, or even the full circumference or perimeter of a vibration sensitive element, thereby blocking movement of the vibration sensitive element in up to all directions in a plane parallel to the circumference or the perimeter.

[0016] Furthermore, according to at least some examples, the planar portion may further comprise a third edge section and / or the planar portion may further be connected to a third side panel of the folded foldable element. The positioning may further comprise positioning so that the third edge section is in contact with a further vibration sensitive element or with another portion of the substantially rigid structure. Additionally or alternatively, so that the third side panel has a normal vector substantially parallel to the first direction and is in contact with a further vibration sensitive element or with another portion of the substantially rigid structure.

[0017] In doing so, movement of a further vibration sensitive element may further be blocked or a blocking of the vibration sensitive element may be strengthened due to the additional support from the another portion of the substantially rigid structure, so that securement of the heating device during transport is further increased.

[0018] Further, according to at least some examples, the positioning of the folded foldable element may further comprise positioning the folded foldable element at least partially in the first direction between a further vibration sensitive element and the substantially rigid structure and / or a further substantially rigid structure.

[0019] In doing so, movement of a further vibration sensitive element may further be blocked or a blocking of the vibration sensitive element may be strengthened due to the additional support from the further substantially rigid structure, so that securement of the heating device during transport is further increased.

[0020] In addition, according to at least some examples, the method may further comprise folding and positioning a second foldable element at least partially in a third direction between the vibration sensitive element and the substantially rigid structure for securing the mobile mechanical assembly during transport, wherein the third direction is in the plane and is non-parallel to the first direction.

[0021] In doing so, movement of the vibration sensitive element may be blocked more efficiently and the vibration sensitive element may be held in position more reliably.

[0022] Moreover, according to at least some examples, the planar portion may comprise at least one of a triangular shape, a rectangular shape, a polygonal shape, a circular shape, a shape negative to any of these shapes, and a combination of any of these shapes.

[0023] In doing so, the planar portion may comprise a shape which is complementary to a shape of a portion of the vibration sensitive element at which the planar portion contacts the vibration sensitive element. Hence, a contact length between the planar portion and the vibration sensitive element may be increased and a blocking of the vibration sensitive element may be made more efficiently, which may result in the vibration sensitive element being held in position more reliably.

[0024] Furthermore, according to at least some examples, the foldable element may comprise at least one of carboard, recycled material, and extruded plastic, preferably wherein the foldable element is made of cardboard. The cardboard may be corrugated cardboard, which has a higher strength and stiffness to weight ratio than regular cardboard.

[0025] In doing so, materials may be used for the folded foldable element, which are comparatively environmentally friendly in that comparatively low energy or a reduced resource amount is required for the production of these materials and in that these materials are comparatively easy to recycle. Moreover, these materials may be inexpensive.

[0026] In particular, a foldable element comprising carboard or corrugated carboard has the further advantageous effect of being easily recyclable, and to have a low environmental impact for itself, for example in comparison to a plastic material, and for a tooling of the foldable element, for example since a foldable element comprising carboard does not need a mold made of steel for the production of such element, for example in comparison to a foldable element comprising a plastic material. Furthermore, the foldable element comprising carboard or corrugated carboard may allow for a local production. Additionally, if the foldable element comprising carboard or corrugated carboard may, due to an installation error, not be removed from inside the heating device's casing after installation of the heating device, such foldable element, for example in case the heating device represents a heat pump, will disintegrate on its own as a result of the forces exerted by the heat pump's compressor's vibrations and the humidity in the heat pump's environment, which will reduce the foldable element's mechanical capacities and will accelerate the foldable element's destruction.

[0027] Further, according to at least some examples, the folded foldable element may comprise a box shape.

[0028] Accordingly, the foldable element may be folded to a volumetric body, which may allow to easily occupy a comparatively large empty space in the heating device's casing. In doing so, a material usage for filling such empty space to secure the heating device for transport may be avoided.

[0029] In addition, according to at least some examples, the method may further comprise arranging tools and / or textual information in the box-shaped folded foldable element.

[0030] In doing so, tools and / or textual information are reliably available at the installation side when the heating device is to be installed.

[0031] According to a further embodiment, the method may further comprise positioning at least one layer of corrugated carboard at least partially in the first direction between the vibration sensitive element and the substantially rigid structure so that a first portion of the at least one layer of corrugated carboard is at least in a linear contact with the substantially rigid structure, and a second portion of the at least one layer of corrugated carboard is at least in a linear contact with the vibration sensitive element.

[0032] The use of carboard is advantageous, in that it may be positioned and removed comparatively fast, for example in comparison to a fixing by using screws. Moreover, no tools may be required for the positioning and the removal of the carboard. Further, as the carboard may be transported in a planar configuration, a reduction of the dimension of the part is achieved when it needs to be transported, for example between a manufacturing location of the carboard and an installation location at which the carboard is positioned inside the heating device's casing, and / or between the installation location and a recycling plant for disposing the carboard. Further, such carboard allows for more compacity during the whole supply chain comprising transport and stocking, and thus a reduction of total CO2 emission for the transport is achieved, because more carboard in a planar configuration can be loaded in a same transportation vehicle. Further, when using corrugated cardboard, folding may be avoided, thus using corrugated carboard may be less time-consuming and more time-efficient in comparison to using elements which need to be folded prior to usage.

[0033] Moreover, according to at least some examples regarding the first aspect and / or the second aspect, the method(s) may further comprise removing the positioned folded foldable element and / or the positioned corrugated carboard before operating the heating device by one or more of sliding, bending, tearing and cutting the positioned folded foldable element and / or the positioned corrugated carboard outside its position.

[0034] Hence, a quick removal is enabled, wherein the usage of tools is avoided.

[0035] According to a third aspect, there is disclosed a manufacturing method for a foldable element for use in the method according to the first aspect and / or for use in the method according to the second aspect. The method comprises providing a planar material, such as cardboard, and cutting or punching out a shape comprising the planar portion, the method optionally further comprising a step of providing folding-lines, such as via marking, embossing or hole punching and / or providing an attachment area for interconnecting one or more sections of the foldable element to one another. The attachment area might be provided with an adhesive, such as glue, and / or a clipping for folding over another section of the foldable element.

[0036] Hence, the foldable element may be manufactured in a comparatively fast and uncomplex manner.

[0037] According to a fourth aspect, there is disclosed a use of a foldable element for securing a heating device, such as a heat pump, during transport. The heating device comprises a substantially rigid structure, such as a frame, a vibration sensitive element, such as a compressor and / or a part of a refrigerant circuit, and the foldable element. A part of a refrigerant circuit may be one or more parts, or all parts of the refrigerant circuit. The vibration sensitive element is attached to the substantially rigid structure with a predetermined amount of movability in at least a first direction with respect to the substantially rigid structure. The first direction is in a plane that is horizontal when the heating device is in a use-position, and the foldable element, when folded, forms a three-dimensional shape, is movable from a planar configuration to a folded configuration and, when folded, comprises a planar portion. The planar portion comprises a first edge section and a second edge section, and / or the planar portion is connected to a first side panel of the folded foldable element and to a second side panel of the folded foldable element. The use of the foldable element comprises positioning the folded foldable element at least partially in the first direction between the vibration sensitive element and the substantially rigid structure so that the first edge section is in contact with the substantially rigid structure, the second edge section is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction. Additionally or alternatively, so that the first side panel has a normal vector substantially parallel to the first direction and is in contact with the substantially rigid structure, the second side panel has a normal vector substantially parallel to the first direction and is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction.

[0038] Such use is advantageous, in that the folded foldable element may be positioned and removed comparatively fast, for example in comparison to a fixing by using screws. Moreover, no tools may be required for the positioning and the removal of the folded foldable element. Further, as the folded foldable element is a folded part and may thus be transported in an unfolded, i.e. planar configuration, a reduction of the dimension of the part is achieved when it needs to be transported for the use, for example between a manufacturing location of the foldable element and an installation location at which the foldable element is positioned inside the heating device's casing, and / or between the installation location and a recycling plant for disposing the folded element. Further, using such foldable element allows for more compacity during the whole supply chain comprising transport and stocking, and thus a reduction of total CO2 emission for the transport is achieved, because more foldable elements in an unfolded, i.e. planar configuration can be loaded in a same transportation vehicle.

[0039] According to a fifth aspect, there is disclosed a heating device, such as a heat pump, comprising a substantially rigid structure, such as a frame, a vibration sensitive element, such as a compressor and / or a part of a refrigerant circuit, and a foldable element for securing the heat pump during transport. A part of a refrigerant circuit may be one or more parts, or all parts of the refrigerant circuit. The vibration sensitive element is attached to the substantially rigid structure with a predetermined amount of movability in at least a first direction with respect to the substantially rigid structure. The first direction is in a plane that is horizontal when the heating device is in a use-position. The foldable element, when folded, forms a three-dimensional shape, is movable from a planar configuration to a folded configuration and, when folded, comprises a planar portion. The planar portion comprises a first edge section and a second edge section, and / or wherein the planar portion is connected to a first side panel of the folded foldable element and to a second side panel of the folded foldable element. The folded foldable element is positioned at least partially in the first direction between the vibration sensitive element and the substantially rigid structure so that the first edge section is in contact with the substantially rigid structure, the second edge section is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction. Additionally or alternatively, so that the first side panel has a normal vector substantially parallel to the first direction and is in contact with the substantially rigid structure, the second side panel has a normal vector substantially parallel to the first direction and is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction.

[0040] The heating device is advantageous, in that the heating device comprises at least one folded foldable element to be secured for transport, wherein the at least one folded foldable element may be positioned and removed fast, with no tools being required. Further, the heating device comprising the foldable element comprising carboard or corrugated carboard, will not be damaged in operation in case the folded foldable element was not removed prior to the operation due to an installation error. For example, in case the heating device representing a heat pump, the folded foldable element will disintegrate on its own as a result of the forces exerted by the heat pump's compressor's vibrations and the humidity in the heat pump's environment, which will reduce the foldable element's mechanical capacities and will accelerate the foldable element's destruction.

[0041] Moreover, according to at least some examples, the heating device may further comprise a second folded foldable element positioned at least partially in a second direction between the vibration sensitive element and the substantially rigid structure, wherein the second direction is in the plane and is non-parallel to the first direction.

[0042] In doing so, movement of the vibration sensitive element may be blocked more efficiently and the heating device may be secured for transport more reliably.

DETAILED DESCRIPTION

[0046] According to several examples, the present disclosure shows folded foldable elements, like folded or bended cardboard sheets for example, wherein the cardboard sheets are folded to get mechanical resistance when filling a gap between a heat pump's casing and a vibration sensitive element of the heat pump for example, so that displacement of the vibration sensitive element is avoided.

[0047] Hence, according to several examples, one or several folded foldable elements are used to hold several vibration sensitive elements inside a heating device's casing during transport. Such foldable elements are carboards for example, which, when folded, are preferably folded by a 90° angle for reasons stability and resistivity. When folded, the foldable elements create a three-dimensional shape with two main different stiffnesses. In a direction of a planar portion of the folded foldable element, i.e. in a direction substantially perpendicular to a normal vector of the planar portion, the folded foldable element is very stiff, not flexible and offers a very good resistance to effort on this direction. In a direction of a thickness of the planar portion of the folded element, i.e. in a direction substantially parallel to the normal vector of the planar portion, the folded foldable element is able to deform slightly and offers some flexibility to absorb mechanical stress. In many cases, in the direction of the thickness, the folded foldable element allows for a bigger support surface than in the direction of a folded foldable element's planar portion, because a contact surface, i.e. a surface of the folded foldable element which contacts a vibration sensitive element for example, dependents on the thickness of the planar portion.

[0048] According to several examples, these folded foldable elements are positioned inside the casing of a heat pump for example and are used to hold several vibration sensitive elements of the heat pump. A vibration sensitive element may be understood to represent a movable component inside the heat pump's casing, which is not rigidly fixed on purpose. This is particular the case for the compressor, for example, which is supported with a damping mechanism comprising rubber feet for example, which allows some displacements for the compressor when in operation, especially in a horizontal plane in relation to an arrangement of the heat pump when in operation. Such damping mechanism may absorb a certain amount of the vibration of the compressor when the compressor is in operation. As the compressor includes massive and vibration sensitive elements at high frequency, for example in a range from 10 - 100 Hz, the compressor generates vibrations which can lead to noise and to premature fatigue of the components attached to the compressor. This fatigue can create breakage, for example, of the piping which is connected to the compressor, the duct of the refrigerant fluid inside the compressor, and the whole refrigerant circuit. If a breakage happens, the heat pump may not work anymore and there is a safety risk for users due to the use of a flammable refrigerant and its high pressure for example. The safety risk may comprise a risk of explosion, fire due to flammability and / or burst due to pressure.

[0049] However, when the heat pump is transported, such damping mechanism like rubber feet for example of the compressor and other associated components fixed to the compressor can allow excessive displacements of these vibration sensitive elements. During transport, accelerations, shocks, tilting and vibrations happen. As the compressor is heavy, with a center of gravity above all its fixing means, there is a strong risk of tipping of the compressor due to kinetic energy. This can lead to a breakage of a whole range of components, namely, those to which the compressor is attached, components of the compressor, components adjacent to the compressor, the compressor attachment screws, etc.

[0050] In the present disclosure, to prevent such happening, the purpose of the present disclosure is to use folded foldable elements, which are positioned between the vibration sensitive element comprising components of the heat pump that must be blocked because they can move without such folded foldable element, and the fixed components of the heat pump. The fixed components of the heat pump may be understood to represent structural components or immovable components and may be understood to form a substantially rigid structure.

[0051] According to several examples, positioning the folded foldable elements may involve positioning the folded foldable elements between: (i) all the components which need to be protected and which are fixed to an arrangement of components subject to movement due to the use of a damping mechanism for example. Such arrangement of components, like a block or a block of components for example, may be understood to represent at least one of a compressor, a heat exchanger, a liquid receiver, a piping, a pump and an expansion valve, for example. And (ii) a substantially rigid structure, which may be understood to comprise structural parts like at least one of a panel of a heat pump's casing, an air duct, a fixed housing such as an electrical box, and an acoustic material applied on at least one of the panels, for example. These structural parts are rigid and immovable.

[0052] The folded foldable elements are installed during production of the heat pump for example and are removed during the installation phase when the heat pump is at the installation site. Indeed, an installer needs to have access to the inside of a heat pump's casing during installation to realize other tasks, like electric or hydraulic connections for example with the installation site. Hence, at the same time, the installer may remove the folded foldable elements before operation of the compressor. No tools may be required for such removal.

[0053] Nowadays, for transporting a heat pump, a securing of the heat pump is made with molded plastic parts and / or screws for example. Carboard, which is a resource-efficient, low-cost, low-carbon alternative to nowadays solutions for securing a heat pump during transport, may not be strong enough by itself in an unfolded configuration compared to plastic. However, when folded with appropriate design, carboard offers sufficient resistance to achieve and realize this function.

[0054] To achieve this, a folded foldable element or an assembly of folded foldable elements is designed in such a way that a vibration sensitive element inside the heat pump's casing is blocked in at least two non-parallel and horizontal directions with respect to the heat pump's substantially rigid structure comprising fixed structural and immovable components of the heat pump. Preferably, at least three directions are used with at least two thereof being non-parallel. This makes it possible to "triangulate" a vibration sensitive element and / or an assembly of vibration sensitive elements and to prevent the vibration sensitive element and / or the assembly of vibration sensitive elements from moving in the horizontal plane. There are therefore at least two, preferably three, material-filled segments between a vibration sensitive element and the substantially rigid structure. A segment may be understood to represent a part of a folded foldable element, so that one folded foldable element may comprise one or more segments. Hence, one folded foldable element may allow to provide several segments, or several folded foldable elements may be required to provide several segments. These segments can be made in different ways. First, by a plate or plates of horizontally arranged material, along the length of a horizontally positioned plate, wherein such plate or plates may be understood to represent a planar portion or planar portions of a folded foldable element. One edge or edge section of the plate is in contact with the vibration sensitive element and another edge or edge section of the plate is in contact with the substantially rigid structure. Second, by using a box on which vertical planes of plates, like a first plate and a second plate each having a normal vector substantially parallel to the horizontal direction for example, are used to have contact with the vibration sensitive element and the substantially rigid structure, the vertical planes being connected with horizontally folded plates. Accordingly, the box may represent a folded foldable element and the horizontally folded plates may be understood to represent planar portions of the folded foldable element. The minimum two or three segments may be in the same horizontal plane or in parallel planes. Hence, the several planar portions may be in the same horizontal plane or in parallel planes. At least two or three segments can be stuck with a single folded foldable element having several support zones, i.e. several edge sections and / or several vertical planes of plates for contacting the vibration sensitive element and the substantially rigid structure, or with a combination of folded foldable elements. By having at least two non-parallel but horizontal directions which are blocked, it is ensured that there is substantially no displacement of the vibration sensitive element, like a compressor or associated components for example, in the horizontal plane. In particular, depending on the particular configuration of the folded foldable element, movement is at least blocked along a first directional path in both non-parallel but horizontal directions, thereby damping the effect of any remaining movement along a second directional path in both non-parallel but horizontal directions to a level that might be acceptable.

[0055] Referring now to Figure 1, Figure 1 shows an explosion diagram of a heat pump 100 according to several examples of the disclosure. In Figure 1, based on the orientation of the heat pump 100 as shown in Figure 1 without being limited to such orientation, a top panel 110 of the heat pump 100 is removed, a side panel 120 of the heat pump 100 is removed and a front panel 130 of the heat pump 100 is removed, so that components inside the heat pump's 100 casing are visible. A rear panel 140 of the heat pump 100 is shown as not being removed. For example, there is shown inside the heat pump's 100 casing an example for an assembly of vibration sensitive elements 150, an example for an assembly of folded foldable elements 160, an example for an air duct 170, and an example for a damping mechanism 180 comprising rubber feet for vibration attenuation for example. The damping mechanism 180 may be realized by a holding plate standing on such rubber feet, wherein the assembly of vibration sensitive elements 150 is arranged on the holding plate. Hence, in case the holding plate may move due to the elasticity of the rubber feet, also the assembly of vibration sensitive elements 150 will move. Thus, the assembly of vibration sensitive elements 150 as well as a vibration sensitive element among such assembly are / is considered movable. The shown assembly of vibration sensitive elements 150 mainly corresponds to the heat pump's 100 refrigerant circuit. The panels 110, 120, 130 and 140 as well as the air duct 170 for example may be understood to represent at least part of a substantially rigid structure of the heat pump 100. The substantially rigid structure is immovable, i.e. the substantially rigid structure may be understood as not to move during transport of the heat pump 100 for example. In other words, in case the heat pump 100 may be transported, the assembly of vibration sensitive elements 150 may move relative to the substantially rigid structure, due to the assembly of vibration sensitive elements 150 being arranged on the holding plate of the damping mechanism 180. The assembly of folded foldable elements 160 in Figure 1 comprises three different folded foldable elements 161, 162 and 163, which are positioned inside the heat pump's 100 casing for securing the assembly of vibration sensitive elements 150 and / or an individual vibration sensitive element among such assembly. For example and as depicted, the folded foldable element 161 is positioned between a portion of the assembly of vibration sensitive elements 150, the top panel 110, side panel 120, the front panel 130 and the rear panel 140. Hence, the folded foldable element 161 may be positioned to be in contact with a portion of the assembly of vibration sensitive elements 150, with a portion of the top panel 110, with a portion of the side panel 120, with a portion of the front panel 130 and with a portion of the rear panel 140, thereby holding the portion of the assembly of vibration sensitive elements 150 in position.

[0056] Figure 2 shows a front view of the heat pump 100 of Figure 1 according to several examples of the disclosure. In particular, Figure 2 shows the three different folded foldable elements 161, 162 and 163 in more detail. For example, further to the folded foldable element 161 as described above with reference to Figure 1, the folded foldable element 162 is in contact with a portion of the air duct 170 and a portion of the assembly of vibration sensitive elements 150. The folded foldable element 163 is in contact with a portion of the front panel 130, a portion of the air duct 170, and a portion of the assembly of vibration sensitive elements 150.

[0057] Figures 3 to 6 show the assembly of vibration sensitive elements 150 according to Figures 1 and 2, as well as the positioning of the three folded foldable elements 161, 162 and 163 150 according to Figures 1 and in more detail and from different perspectives. For example, the assembly of vibration sensitive elements 150 may comprise, among a plurality of components, a compressor 152, a liquid receiver 151 being a tank for holding a volume of refrigerant, different types of piping 153 and a hydraulic pump 154. The liquid receiver 151, for instance, is held in position, i.e. secured by the folded foldable element 161, wherein the compressor 152, for instance, is secured by the folded foldable elements 162 and 163. In addition, the holding plate of the damping mechanism 180 is illustrated as standing on rubber feet 181. In the top view as shown in Figure 4, the liquid receiver 151 is surrounded by the folded foldable element 161, wherein the edge of the circular opening of the folded foldable element 161 contacts the liquid receiver 151. The perspective shown in Figure 4 is to look substantially perpendicular at the horizontal plane of the heat pump 100, wherein the horizontal plane represents the x-y-plane as indicated in Figure 4. Hence, the folded foldable element 161 blocks a movement of the liquid receiver 151 in any direction in the horizontal plane. The folded foldable elements 162 and 163 may block a horizontal movement of the compressor 152 substantially in the -x-direction, the +y-direction and the -y-direction (or any combination thereof). Movement of the compressor 152 in the +x-direction may be blocked by the folded foldable element 161, since the folded foldable element 161 blocks movement of the assembly of vibration sensitive elements 150 in the +x-direction, for example.

[0058] It shall be noted that the expression "to block a movement" comprises to at least limit or reduce the movement as well as to avoid any movement.

[0059] Referring now to Figures 7 and 8, Figure 7 shows an illustrative example of the folded foldable element 161 in a top view perspective rotated by -90° in the horizontal plane in comparison to the perspective shown in Figure 4., wherein Figure 8 shows the folded foldable element 161 in a three-dimensional view for improving understandability of how the folded foldable element 161 is shaped. The folded foldable element 161 is in contact with several portions of the substantially rigid structure, for example with structural parts 701, 702 and 703. Structural part 701 may represent a portion of the side panel 120, structural part 702 may represent a portion of the rear panel 140 and structural part 703 may represent a portion of the air duct 170. Further, the folded foldable element 161 comprises three planar portions 710, 720 and 730. The planar portions 710, 720 and 730 are positioned to have a normal vector substantially perpendicular to the horizontal plane, i.e. the x-y-plane. Hence, the planar portions 710, 720 and 730 substantially lie in the horizontal plane. The expression substantially perpendicular as used throughout the present disclosure may be understood to be in a range from 90°±5°.

[0060] The planar portions 710, 720 and 730 are connected to an upfolded portion 740 of the folded foldable element 161, upfolded by an angle of substantially 90°, i.e. in a range from 90°±5°, against the planar portions 710, 720 and 730. In detail, the planar portion 710 is connected to the upfolded portion 740 at an edge section 711a of the planar portion 710. The planar portion 720 is connected to the upfolded portion 740 at an edge section 721 of the planar portion 720. The planar portion 730 is connected to the upfolded portion 740 at an edge section 731a of the planar portion 730. The upfolded portion 740 contacts the structural part 701. Hence, each of the edge sections 711a, 721 and 731a is in contact with the structural part 701.

[0061] Further, the planar portion 710 is further connected to an upfolded portion 750 of the folded foldable element 161, upfolded by an angle of substantially 90° against the planar portions 710. In detail, the planar portion 710 is connected to the upfolded portion 750 at an edge section 711b of the planar portion 710. The upfolded portion 750 contacts the structural part 702. Hence, the edge section 711b is in contact with the structural part 702.

[0062] Further, the planar portion 710 is further connected to an upfolded portion 760 of the folded foldable element 161, upfolded by an angle of substantially 90° against the planar portions 710. In detail, the planar portion 710 is connected to the upfolded portion 760 at an edge section 711c of the planar portion 710. The upfolded portion 760 contacts the structural part 703. Hence, the edge section 711c is in contact with the structural part 703.

[0063] Further, the planar portions 720 and 730 are connected to an upfolded portion 770 of the folded foldable element 161, upfolded by an angle of substantially 90° against the planar portions 720 and 730. In detail, the planar portion 720 is connected to the upfolded portion 770 at an edge section 722 of the planar portion 720. The planar portion 730 is connected to the upfolded portion 770 at an edge section 732 of the planar portion 730.

[0064] The planar portion 730 further comprises another edge section 731b, which may be brought in contact with another structural part for example.

[0065] It shall be noted that the folded foldable element 161 may comprise more or less than the three planar portions 710, 720 and 730. The folded foldable element 161 may be in contact with more or less than the three structural parts 701, 702 and 703.

[0066] The planar portion 710 further comprises a circular-shaped opening 780 having an edge section 712a substantially of a shape of a half circle near the edge section 711a, and having another edge section 712b substantially of a shape of a half circle near the edge section 711c. The opening 780 is designed to have a complementary shape to the shape of a cylinder 790. Hence, the edge sections 712a and 712b of the opening 780 contact the cylinder 790. The cylinder is an example of a vibration sensitive element, for example a compressor 152 or a liquid receiver 151, which may be part of an assembly of vibration sensitive elements 150. The opening 780 may be shaped to conform to at least a portion of a cross-sectional shape of a vibration sensitive element.

[0067] Referring now to Figure 9, Figure 9 shows the folded foldable element 162 according to several examples of the disclosure. The folded foldable element 162 has a box-shape and comprises two planar portions 910a and 910b, which are in contact with side panels or plates 911, 912, 913 and 914. The folded foldable element 162 may be positioned inside the heat pump's 100 casing so that the planar portions 910a and 910b substantially lie, i.e. in a range of ±5°, in the horizontal plane. Further, the plate 911 of the folded foldable element 162 may be at least in parts in contact with a portion of the assembly of vibration sensitive elements 150 as illustrated in Figures 3 and 4 for example, where the plate 911 at least partly contacts the compressor 152. The plate 912 of the folded foldable element 162 may be at least in parts in contact with a portion of the substantially rigid structure as illustrated in Figures 3 and 4 for example, where the plate 912 at least partly contacts a portion of the air duct 170.

[0068] Referring now to Figure 10, Figure 10 shows a method for securing a heating device during transport according to several examples of the disclosure.

[0069] The method is a method for securing a heating device, such as a heat pump, during transport. The heating device comprises a substantially rigid structure, such as a frame, and a vibration sensitive element, such as a compressor and / or a part of a refrigerant circuit. A part of a refrigerant circuit may be one or more parts, or all parts of the refrigerant circuit. The vibration sensitive element is attached to the substantially rigid structure with a predetermined amount of movability in at least a first direction with respect to the substantially rigid structure. The first direction is in a plane that is horizontal when the heating device is in a use-position.

[0070] The method, after a start in Step S1000, comprises, in Step S1010, folding a foldable element to form a three-dimensional shape. The foldable element is movable between a planar configuration and a folded configuration, and the foldable element comprises a planar portion. The planar portion comprises a first edge section and a second edge section. Additionally or alternatively, the planar portion is connected to a first plate of the folded foldable element and to a second plate of the folded foldable element.

[0071] The method further comprises, in Step S1020, positioning the folded foldable element at least partially in the first direction between the vibration sensitive element and the substantially rigid structure so that the first edge section is in contact with the substantially rigid structure, the second edge section is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction. Additionally or alternatively, so that the first plate has a normal vector substantially parallel to the first direction and is in contact with the substantially rigid structure, the second plate has a normal vector substantially parallel to the first direction and is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction.

[0072] The method ends in Step S1030 and may return to Step S1000.

[0073] It shall be noted that the planar portion may represent a horizontal plane going from one edge of a vibration sensitive element to another edge of the substantially rigid structure. The planar portion may represent a vertical plane. The planar portion may represent any plane in a rotation position between a horizontal plane and a vertical plane if the planar portion has a normal vector substantially perpendicular to the first direction.

[0074] It shall further be noted that the vibration sensitive element, wherein the vibration sensitive element may be understood to represent a single vibration sensitive element or an assembly of vibration sensitive elements, may represent at least one component of a refrigerant circuit for example, which is mounted to the rest of the structure, i.e. to the rest of the heating device via rubber feet as being part of a damping mechanism. Instead of rubber feet, anti-vibration feet or anti-vibration pads may be used, which are usually made of a rubber-like material, to prevent vibrations of a vibration sensitive element, for example of the compressor, to be transferred to the rest of the structure and may thus result in the whole structure vibrating and making noise. Some piping as another example for a vibration sensitive element may be attached between the compressor and a portion of the substantially rigid structure. Such piping may be provided with some bends, to compensate for movement between the piping and the substantially rigid structure. However, a movement as might potentially occur during transport of the heating device could result in a permanent deformation, damage and leakages of the piping. The folded foldable element may allow to prevent such deformation, damage and leakages.

[0075] The folded foldable element is further advantageous, in that it may be positioned and removed comparatively fast, for example in comparison to a fixing by using screws. Moreover, no tools may be required for the positioning and the removal of the folded foldable element. Further, as the folded foldable element is a folded part and may thus be transported in an unfolded, i.e. planar configuration, a reduction of the dimension of the part is achieved when it needs to be transported, for example between a manufacturing location of the foldable element and an installation location at which the foldable element is positioned inside the heating device's casing, and / or between the installation location and a recycling plant for disposing the folded element. Further, such foldable element allows for more compacity during the whole supply chain comprising transport and stocking, and thus a reduction of total CO2 emission for the transport is achieved, because more foldable elements in an unfolded, i.e. planar configuration can be loaded in a same transportation vehicle.

[0076] Moreover, according to at least some examples, the positioning may further comprise positioning the folded foldable element at least partially in a second direction between the vibration sensitive element and the substantially rigid structure, wherein the second direction is in the plane and is non-parallel to the first direction.

[0077] In doing so, movement of the vibration sensitive element may be blocked more efficiently and the vibration sensitive element may be held in position more reliably. Particularly, the folded foldable element may hold a substantial section of the circumference, or even the full circumference of a vibration sensitive element, thereby blocking movement of the vibration sensitive element in up to all directions in a plane parallel to the circumference.

[0078] Furthermore, according to at least some examples, the planar portion may further comprise a third edge section and / or the planar portion may further be connected to a third side panel of the folded foldable element. The positioning may further comprise positioning so that the third edge section is in contact with a further vibration sensitive element or with another portion of the substantially rigid structure. Additionally or alternatively, so that the third side panel has a normal vector substantially parallel to the first direction and is in contact with a further vibration sensitive element or with another portion of the substantially rigid structure.

[0079] In doing so, movement of a further vibration sensitive element may further be blocked or a blocking of the vibration sensitive element may be strengthened due to the additional support from the another portion of the substantially rigid structure, so that securement of the heating device during transport is further increased.

[0080] Further, according to at least some examples, the positioning of the folded foldable element may further comprise positioning the folded foldable element at least partially in the first direction between a further vibration sensitive element and the substantially rigid structure and / or a further substantially rigid structure.

[0081] In doing so, movement of a further vibration sensitive element may further be blocked or a blocking of the vibration sensitive element may be strengthened due to the additional support from the further substantially rigid structure, so that securement of the heating device during transport is further increased.

[0082] In addition, according to at least some examples, the method may further comprise folding and positioning a second foldable element at least partially in a third direction between the vibration sensitive element and the substantially rigid structure for securing the mobile mechanical assembly during transport, wherein the third direction is in the plane and is non-parallel to the first direction.

[0083] In doing so, movement of the vibration sensitive element may be blocked more efficiently and the vibration sensitive element may be held in position more reliably.

[0084] Moreover, according to at least some examples, the planar portion may comprise at least one of a triangular shape, a rectangular shape, a polygonal shape, a circular shape, a shape negative to any of these shapes, and a combination of any of these shapes.

[0085] In doing so, the planar portion may comprise a shape which is complementary to a shape of a portion of the vibration sensitive element at which the planar portion contacts the vibration sensitive element. Hence, a contact length between the planar portion and the vibration sensitive element may be increased and a blocking of the vibration sensitive element may be made more efficiently, which may result in the vibration sensitive element being held in position more reliably.

[0086] Furthermore, according to at least some examples, the foldable element may comprise at least one of carboard, recycled material, and extruded plastic, preferably wherein the foldable element is made of cardboard. The cardboard may be corrugated cardboard.

[0087] Corrugated cardboard may have a higher strength and stiffness to weight ratio than regular cardboard.

[0088] In doing so, materials may be used for the folded foldable element, which are comparatively environmentally friendly in that comparatively low energy or a reduced resource amount is required for the production of these materials and in that these materials are comparatively easy to recycle. Moreover, these materials may be inexpensive.

[0089] In particular, a foldable element comprising carboard or corrugated carboard has the further advantageous effect of being easily recyclable, and to have a low environmental impact for itself, for example in comparison to a plastic material, and for a tooling of the foldable element, for example since a foldable element comprising carboard does not need a mold made of steel for the production of such element, for example in comparison to a foldable element comprising a plastic material. Furthermore, the foldable element comprising carboard or corrugated carboard may allow for a local production. Additionally, if the foldable element comprising carboard or corrugated carboard may, due to an installation error, not be removed from inside the heating device's casing after installation of the heating device, such foldable element, for example in case the heating device represents a heat pump, will disintegrate on its own as a result of the forces exerted by the heat pump's compressor's vibrations and the humidity in the heat pump's environment, which will reduce the foldable element's mechanical capacities and will accelerate the foldable element's destruction.

[0090] In more detail, an advantage of using such a foldable element is that it may be made from planar material, which is easy and compact to stack, and thus relatively cheap to have in storage and transport. Moreover, the tooling for making the desired shape and size of a foldable element from a planar material is relatively cheap to buy and run, and various sizes and shapes of foldable elements can be produced with the same base material and equipment. Moreover, during installation of the heating device at the installation side, the planar material, for example a removed and unfolded foldable element, might be put to additional use for protecting the flooring for example.

[0091] It shall be noted that other materials can be used as long as a planar foldable element is achieved. Preferably carboard as outlined above but other materials could be used such as an extruded plastic plate (for example an Akylux ®< plate). Same functions can be ensured by an extruded plastic plate but without the beneficial environment aspect of carboard-based solutions. On the other side, materials and parts comprising extruded plastic can be more likely reused for transporting another heating device.

[0092] Further, according to at least some examples, the folded foldable element may comprise a box shape.

[0093] Accordingly, the foldable element may be folded to a volumetric body, which may allow to easily occupy a comparatively large empty space in the heating device's casing. In doing so, a material usage for filling such empty space to secure the heating device for transport may be avoided.

[0094] The expression "box shape" is intended to comprise a cuboid shape, but also a parallelepiped shape or a spherical space or any geometrical shape, which may be understood to represent a volumetric body which comprises an empty space inside the volumetric body. Moreover, such volumetric body may be a closed volumetric body, i.e. with no opening. Also, such volumetric body may be an open volumetric body, i.e. at least a portion of a panel of the volumetric body may be removed.

[0095] In addition, according to at least some examples, the method may further comprise arranging tools and / or textual information in the box-shaped folded foldable element.

[0096] In doing so, tools and / or textual information are reliably available at the installation site when the heating device is to be installed.

[0097] In more detail, it should be noted that the folded foldable elements in box-shape or tube-shape or in shape of any volumetric body for example can be used as a housing for parts which need to be used during installation of the heating device, for example manuals, accessories, labels, without being limited to that. Usually, these parts are put outside the casing of the heating device, in the heating device's packaging, in a dedicated carboard or plastic bag. By having the manual and associated parts hold within a folded foldable element for example, they can't fall down during the transport, they can't be damaged, and it allows to remove a dedicated carboard or bag. Moreover, the folded foldable element may have a function necessary for the installation of the heat pump, for example the folded foldable element may comprise (e.g. shown as being printed onto a surface of the folded foldable element) installation pattern including distances to be respected when drilling or mounting on the installation site.

[0098] Referring now to Figure 11, Figure 11 shows a method for securing a heating device during transport according to several examples of the disclosure.

[0099] The method is a method for securing a heating device, such as a heat pump, during transport. The heating device comprises a substantially rigid structure, such as a frame, and a vibration sensitive element, such as a compressor and / or a part of a refrigerant circuit. The vibration sensitive element is attached to the substantially rigid structure with a predetermined amount of movability in at least a first direction with respect to the substantially rigid structure. The first direction is in a plane that is horizontal when the heating device is in a use-position.

[0100] In embodiments, the method, after a start in Step S1100, may comprise, in Step S1110, positioning at least one layer of corrugated carboard at least partially in the first direction between the vibration sensitive element and the substantially rigid structure so that a first portion of the at least one layer of corrugated carboard is at least in a linear contact with the substantially rigid structure, and a second portion of the at least one layer of corrugated carboard is at least in a linear contact with the vibration sensitive element.

[0101] The method ends in Step S1120 and may return to Step S1100.

[0102] The use of carboard is advantageous, in that it may be positioned and removed comparatively fast, for example in comparison to a fixing by using screws. Moreover, no tools may be required for the positioning and the removal of the carboard. Further, as the carboard may be transported in a planar configuration, a reduction of the dimension of the part is achieved when it needs to be transported, for example between a manufacturing location of the carboard and an installation location at which the carboard is positioned inside the heating device's casing, and / or between the installation location and a recycling plant for disposing the carboard. Further, such carboard allows for more compacity during the whole supply chain comprising transport and stocking, and thus a reduction of total CO2 emission for the transport is achieved, because more carboard in a planar configuration can be loaded in a same transportation vehicle. Further, using corrugated cardboard, folding may be avoided, thus using corrugated carboard may be less time-consuming and more time-efficient in comparison to using elements which need to be folded prior to usage.

[0103] It shall further be noted that alternatively and / or additionally to the method as outlined above with reference to Figure 10, corrugated carboard may be used instead of and / or in addition to a folded foldable element. By using carboard, a thickness of the carboard may be sufficient so that a block of corrugated cardboard can be directly inserted between a vibration sensitive element and the substantially rigid structure without need of folding. One or more of the portions of the block of corrugated cardboard abutting the vibration sensitive element and / or the substantially rigid structure may be edge portions of the block of corrugated cardboard.

[0104] For example, with reference to Figure 12, there is schematically shown, as an example for such block, a carboard element 1200 for securing a heating device during transport according to several examples of the disclosure. The carboard element 1200, i.e. the block, may be formed into a certain three-dimensional shape, for example through cutting an unprocessed block or a block in its initial state to obtain such certain three-dimensional shape. An outline or a perimeter of the unprocessed block or of the block in its initial state is schematically indicated by the dashed lines 1210. Due to a cutting of the block in its initial state, for example, slots, recesses and / or openings 1221, 1222, 1223, 1224, 1225 and / or 1226 may be formed to arrive at the carboard element 1200. The carboard element 1200 has a thickness t of at least 15mm to provide sufficient bending stiffness. The carboard element 1200 may be used to hold a vibration sensitive element in position, i.e. to block movement of the vibration sensitive element. For example, with reference to Figure 4, the carboard element 1200 may be used instead of or additionally to the folded foldable element 161. Accordingly, the carboard element 1200 may be arranged so that part of the liquid receiver 151 may be arranged inside the opening 1222, for example, and so that an arrangement on top of the compressor 152 may run through the opening 1224.

[0105] Moreover, according to at least some examples regarding the method according to Figure 10 or the method according to Figure 11, the method(s) may further comprise removing the positioned folded foldable element and / or the positioned corrugated carboard before operating the heating device by one or more of sliding, bending, tearing and cutting the positioned folded foldable element and / or the positioned corrugated carboard outside its position.

[0106] Hence, a quick removal is enabled, wherein the usage of tools is avoided.

[0107] Referring now to Figure 13, Figure 13 shows a method for manufacturing a foldable element according to several examples of the disclosure.

[0108] The method is a manufacturing method for a foldable element for use in the method according to Figure 10 and / or for use in the method according to Figure 11. The method, after start in Step S1300, comprises, in Step 1310, providing a planar material, such as cardboard, and, in Step 1320, cutting or punching out a shape comprising the planar portion.

[0109] The method ends in Step S1330 and may return to Step S1300.

[0110] The method optionally further comprising a step of providing folding-lines, such as via marking, embossing or hole punching, and / or providing an attachment area for interconnecting one or more sections of the foldable element to one another. The attachment area might be provided with an adhesive, such as glue, and / or a clipping for folding over another section of the foldable element.

[0111] Hence, the foldable element may be manufactured in a comparatively fast and uncomplex manner.

[0112] According to several examples of the present disclosure, there is provided a use of a foldable element for securing a heating device, such as a heat pump, during transport. The heating device comprises a substantially rigid structure, such as a frame, a vibration sensitive element, such as a compressor and / or a part of a refrigerant circuit, and the foldable element. A part of a refrigerant circuit may be one or more parts, or all parts of the refrigerant circuit. The vibration sensitive element is attached to the substantially rigid structure with a predetermined amount of movability in at least a first direction with respect to the substantially rigid structure. The first direction is in a plane that is horizontal when the heating device is in a use-position, and the foldable element, when folded, forms a three-dimensional shape, is movable from a planar configuration to a folded configuration and, when folded, comprises a planar portion. The planar portion comprises a first edge section and a second edge section, and / or the planar portion is connected to a first side panel of the folded foldable element and to a second side panel of the folded foldable element. The use of the foldable element comprises positioning the folded foldable element at least partially in the first direction between the vibration sensitive element and the substantially rigid structure so that the first edge section is in contact with the substantially rigid structure, the second edge section is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction. Additionally or alternatively, so that the first side panel has a normal vector substantially parallel to the first direction and is in contact with the substantially rigid structure, the second side panel has a normal vector substantially parallel to the first direction and is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction.

[0113] Such use is advantageous, in that the folded foldable element may be positioned and removed comparatively fast, for example in comparison to a fixing by using screws. Moreover, no tools may be required for the positioning and the removal of the folded foldable element. Further, as the folded foldable element is a folded part and may thus be transported in an unfolded, i.e. planar configuration, a reduction of the dimension of the part is achieved when it needs to be transported for the use, for example between a manufacturing location of the foldable element and an installation location at which the foldable element is positioned inside the heating device's casing, and / or between the installation location and a recycling plant for disposing the folded element. Further, using such foldable element allows for more compacity during the whole supply chain comprising transport and stocking, and thus a reduction of total CO2 emission for the transport is achieved, because more foldable elements in an unfolded, i.e. planar configuration can be loaded in a same transportation vehicle.

[0114] According to several examples of the present disclosure, there is provided a heating device, such as a heat pump, comprising a substantially rigid structure, such as a frame, a vibration sensitive element, such as a compressor and / or a part of a refrigerant circuit, and a foldable element for securing the heat pump during transport. A part of a refrigerant circuit may be one or more parts, or all parts of the refrigerant circuit. The vibration sensitive element is attached to the substantially rigid structure with a predetermined amount of movability in at least a first direction with respect to the substantially rigid structure. The first direction is in a plane that is horizontal when the heating device is in a use-position. The foldable element, when folded, forms a three-dimensional shape, is movable from a planar configuration to a folded configuration and, when folded, comprises a planar portion. The planar portion comprises a first edge section and a second edge section, and / or wherein the planar portion is connected to a first side panel of the folded foldable element and to a second side panel of the folded foldable element. The folded foldable element is positioned at least partially in the first direction between the vibration sensitive element and the substantially rigid structure so that the first edge section is in contact with the substantially rigid structure, the second edge section is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction. Additionally or alternatively, so that the first side panel has a normal vector substantially parallel to the first direction and is in contact with the substantially rigid structure, the second side panel has a normal vector substantially parallel to the first direction and is in contact with the vibration sensitive element, and the planar portion has a normal vector substantially perpendicular to the first direction, thereby substantially blocking movement of the vibration sensitive element with respect to the substantially rigid structure in the first direction.

[0115] The heating device is advantageous, in that the heating device comprises at least one folded foldable element to be secured for transport, wherein the at least one folded foldable element may be positioned and removed fast, with no tools being required. Further, the heating device comprising the foldable element comprising carboard or corrugated carboard, will not be damaged in operation in case the folded foldable element was not removed prior to the operation due to an installation error. For example, in case the heating device representing a heat pump, the folded foldable element will disintegrate on its own as a result of the forces exerted by the heat pump's compressor's vibrations and the humidity in the heat pump's environment, which will reduce the foldable element's mechanical capacities and will accelerate the foldable element's destruction.

[0116] Moreover, according to at least some examples, the heating device may further comprise a second folded foldable element positioned at least partially in a second direction between the vibration sensitive element and the substantially rigid structure, wherein the second direction is in the plane and is non-parallel to the first direction.

[0117] In doing so, movement of the vibration sensitive element may be blocked more efficiently and the heating device may be secured for transport more reliably.

[0118] Unless specified otherwise, or clear from the context, the phrases "one or more of A, B and C", "at least one of A, B, and C", and "A, B and / or C" as used herein are intended to mean all possible permutations of one or more of the listed items. That is, the phrase "A and / or B" means (A), (B), or (A and B), while the phrase "A, B, and / or C" means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B, and C).
