Description

Technical Field

[0001] The present application relates to a heat pump including a vibration influencer, a method for operating a heat pump, and a method for manufacturing a heat pump. Background Art

[0002] In heat pumps known in the prior art, the individual components of the heat pump, such as the evaporator and the corresponding evaporator tank and / or the compressor and the corresponding compressor tank and / or the condenser and the corresponding condenser tank, are fixedly connected to each other.

[0003] In the publication by Tadayoshi and others: Centrifugal Turbine Refrigerator Using Water as Refrigerant and Lubricant, 11th International Conference on Compressors and Their Systems, Journal of Process Mechanical Engineering, published on July 1, 2020, DOI: 10.1177 / 0954408920938197, a water coolant - heat pump system with a steam turbine compressor is described, in which the compressor and the spiral housing are directly fixedly connected to the evaporator and the compressor tank.

[0004] By fixedly connecting the individual components, vibrations, especially resonances, formed during the operation of the heat pump are transmitted from one component to another. Such vibrations are typically generated in the drive motor of the compressor of the heat pump. Generally, the evaporator and the compressor include tanks with large volumes or large surfaces, which reflect and emit sound waves, and thus facilitate the vibration transmission between the individual components of the heat pump. Tensions and mechanical expansions may also be formed due to temperature differences in different regions of the heat pump, which are formed between one component and another due to the fixed connection of the individual components and which cannot be compensated immediately. The result may be that the heat pump operates in a mechanically and / or thermodynamically unstable manner, and the components are subject to stronger mechanical strains.

[0005] Since the individual components are fixedly connected, for example, the connecting parts of the individual components of the heat pump, such as the spiral housing, the tank, and / or the bypass conduit line, must be manufactured very precisely to ensure a constraint - free installation and thus no internal stress. Summary of the Invention

[0006] The object underlying the present invention is to provide an improved heat pump concept.

[0007] This object is achieved by the heat pump according to claim 1, the method for operating a heat pump according to claim 15, or the method for manufacturing a heat pump according to claim 16.

[0008] The core idea of the present invention is to decouple the vibrations that may be formed in the individual components of the heat pump, especially through the operation of the drive motor and may cause resonance frequencies, from the other components of the heat pump, so as to minimize the transfer of vibrations from one component of the heat pump to another. This increases the service life of the heat pump. It is proposed herein to decouple the drive from other components of the heat pump, such as the evaporator and / or the compressor tank (or container).

[0009] The proposed heat pump includes: an evaporator for evaporating the working liquid to obtain working steam; a compressor for compressing the working steam to obtain compressed working steam; a condenser (or liquefier) for condensing the compressed working steam; and a frame to which the evaporator, condenser and / or compressor are mounted. To decouple potential vibrations, the proposed heat pump further includes a vibration influencer configured to decouple the compressor from the evaporator, condenser and / or frame in terms of vibrations, and / or actively or passively reduce the vibrations of the compressor. The vibration influencer is configured to decouple one component of the heat pump (e.g., the compressor) from another component of the heat pump (e.g., the evaporator) to reduce, especially avoid, the transfer of vibrations from one component (e.g., the compressor) to another component (e.g., the evaporator). The vibration influencer may include one or more elastic connection elements. In particular, elastic connection elements between the individual components of the heat pump can be used to achieve vibration decoupling, i.e., reduce, especially avoid, the transfer of vibrations from one component to another. The elastic connection elements can in particular be implemented as heat-insulated, which means that providing the vibration influencer also provides thermal decoupling of the individual components of the heat pump. In other words, providing the vibration influencer can reduce, especially avoid, the transfer of temperature from one component of the heat pump to another component of the heat pump. The vibration influencer preferably includes tubes or tube bushings as elastic connection elements, which flexibly connect the individual components of the heat pump to each other. The flexible connection should be understood such that the tolerances between the individual components can be easily compensated for by the elastic connection elements. Therefore, precise installation of the heat pump is no longer required. The vibration influencer may additionally preferably include elastic dampers for elastically attaching the helical housing of the heat pump to the frame of the heat pump.

[0010] Another aspect of the present invention relates to a method for operating the heat pump just described, and a method for manufacturing the heat pump just described.

[0011] A method for operating a heat pump, the heat pump including: an evaporator for evaporating the working liquid to obtain working steam; a compressor for compressing the working steam to obtain compressed working steam; a condenser for condensing the compressed working steam; and a frame to which the evaporator, condenser and / or compressor are mounted, includes the steps of: decoupling the compressor from the evaporator, condenser and / or frame in terms of vibrations, and / or actively or passively reducing the vibrations of the compressor.

[0012] Method for manufacturing a heat pump, the heat pump comprising: an evaporator for evaporating an operating liquid to obtain an operating vapor; a compressor for compressing the operating vapor to obtain a compressed operating vapor; a condenser for condensing the compressed operating vapor; and a frame to which the evaporator, the condenser and / or the compressor are mounted, comprising the steps of: forming a vibration influencer to decouple the compressor from the evaporator, the condenser and / or the frame in terms of vibration, and / or actively or passively reducing the vibration of the compressor.

[0013] The advantage of the heat pump concept of the present invention is that it operates in a mechanically and / or thermodynamically stable manner during the operation of the heat pump, wherein furthermore, during the operation of the heat pump, vibrations or temperatures are not transferred from one component to another.

[0014] It should be understood that the individual aspects described in connection with the heat pump can also be implemented as method steps and vice versa. Further details will be discussed below in the description of the figures. Description of the Drawings

[0035] The following will refer to Figures 1 to 19 Describe the individual aspects of the invention described herein. In this application, the same reference numerals refer to the same or elements having the same effect, where in the case of repetition, it is not necessary to explain all the reference numerals in the drawings again.

[0036] Figure 1 Schematically shows the arrangement of a heat pump 100, which includes: an evaporator 10 for evaporating an operating liquid to obtain an operating vapor; a compressor 20 for compressing the operating vapor to obtain a compressed operating vapor; and a condenser 30 for condensing the compressed operating vapor in the form of a hydraulic diagram. According to Figure 1For the hydraulic diagram, the first and second spiral housings 78 are arranged horizontally, particularly in the x-y plane. The first compressor stage 70-1 is connected to the second compressor stage 70-n via an intercooler 42. The intercooler 42 has an intercooling space 43 through which the compressed working fluid passes and is cooled in the intercooling space 43. The intercooling space 43 includes an inlet 47 to the intercooling space 43 and an outlet 46 from the intercooling space 43 to the second compressor stage 70-n. A bypass conduit 84 extends from the outlet 46 from the intercooling space 43 to the second compressor stage 70-n. If only the first compressor stage 70-1 is operated, the compressed working fluid does not pass through the intercooler 42 but through a conduit 45 leading directly to the condenser 30. The intercooling outlet conduit 45 includes a flap 83 that closes when the working fluid is also to pass through the second compressor stage 70-2 or opens when the working fluid from the first compressor stage 70-1 is to be directed directly to the condenser 30. The flap 83 can be configured to be controllable or can be a thermosensitive element. The intercooler 42 includes an intercooling collection tank 44. A bypass conduit or bypass element 85 is arranged between the condenser 30 and the evaporator 10, which also includes a flap 83. The flap 83 in the bypass element 85 can be implemented to be controllable or is a thermosensitive element.

[0037] Figure 2 A perspective view of the heat pump 100 with the above components is shown. Furthermore, it can be derived from Figure 2 that the heat pump 100 includes a frame 40 to which the evaporator 10, the condenser 30, and / or the compressor 20 are mounted. It can also be derived from Figure 2 that the heat pump 100 includes a vibration damper 50 configured to decouple the compressor 20 from the evaporator 10, the condenser 30, and / or the frame 40 in terms of vibration and / or to actively or passively reduce the vibration of the compressor 20. In particular, the individual components of the heat pump, such as the evaporator 10, the compressor 20, the condenser 30, and / or the frame 40, are decoupled from each other, for example, by the vibration damper 50 to reduce, in particular, avoid vibration transfer and / or heat transfer. Furthermore, the evaporator 10 includes an evaporator tank 11, the compressor 20 includes a compressor tank 21, and the condenser 30 includes a condenser tank 31.

[0038] Preferably, the vibration damper 50 includes elastic connection elements 60 between the compressor 20 and the frame 40, between the evaporator 10 and the frame 40, and / or between the condenser 30 and the frame 40. In particular, the vibration damper 50 includes a number of elastic connection elements 60 to decouple the individual components of the heat pump 100, such as the evaporator 10, the compressor 20, the condenser 30, and / or the frame 40, from each other, for example, by the vibration damper 50. Thereby, direct vibration transfer between the individual components of the heat pump 100 can be reduced, in particular, prevented.

[0039] For example, in each of Figure 2 , 3 , 4, 11, 12, 14, 16, and 17, or when combining these figures, it can be seen that the compressor 20 includes a compressor input conduit 22 and a compressor output conduit 24. In addition, the evaporator 10 includes an evaporator output conduit 14. In addition, the condenser 30 includes a condenser input conduit 32. The vibration damper 50 includes elastic connection elements 60 between the compressor output conduit 24 and the condenser input conduit 32 and / or between the evaporator output conduit 14 and the compressor input conduit 22. In particular, at least one elastic connection element 60 can be arranged between different components of the heat pump 100 to mechanically and / or thermally decouple each component of the heat pump 100 from the other components of the heat pump 100.

[0040] Preferably, the compressor 20 includes two or more compressor stages 70, where the compressor input conduit 22 is arranged at the first compressor stage 70-1, and the compressor output conduit 24 is arranged at the second or last compressor stage 70-n, and an intermediate cooling tank is arranged between the first compressor stage 70-1 and the second or last compressor stage 70-n. In this case, the reference numeral n refers to a natural number greater than or equal to 2. In addition, the vibration damper 50 particularly includes elastic connection elements 60 between the intermediate cooling tank and the first compressor stage 70-1 and / or between the intermediate cooling tank and the second or last compressor stage 70-n. In particular, the vibration damper 50 is defined by a plurality of elastic connection elements 60. The plurality of elastic connection elements 60 can be elastic connection elements 60 having different physical properties (e.g., temperature conductivity, Shore hardness, etc.) (see, for example, Figure 6c the table in, where Figure 6c the physical values in the table of

[0041] Preferably, the elastic connection element 60 connected to the frame 40 is implemented as an elastic decoupling element, a metal vibration buffer, a rubber-coated bolt / nut connection, or a metal damper. For example, Figure 6a and 6b show metal vibration (or ) buffers. Figure 7 shows a rubber-coated bolt / nut connection. In particular, one or more spiral housings 78 are suspended at the frame 40 in a damped manner using one or more elastic connection elements 60. For example, three or four dampers 94, i.e., three or four elastic connection elements 60, can be used to suspend or arrange the spiral housing 78 at the frame 40. Preferably, a metal vibration buffer with the following characteristics is used: diameter d = 20 mm, height h = 15 mm, length l = 19 mm (see Figure 6c and Figure 6b ​​​​)。More features of the preferred metal vibration dampers can be derived from Figure 6c in the table, with the reference numeral 105. As Figure 7 The rubber-coated bolt / nut connection shown in can be used, for example, to couple the (multiple) spiral housings 78 to other components of the compressor 20. By using the rubber-coated bolt / nut connection, the mutually coupled components (such as, for example, the spiral housing 78 and other components of the compressor 20) can be guided in the lateral direction. The lateral direction refers to the direction along the coupled components. The rubber-coated bolt / nut connection includes a guide pin 106 to which components of the heat pump can be connected. The lateral direction points along the length of the guide pin 106 (see Figure 7 ).

[0042] Furthermore, the elastic connection element 60 is preferably implemented as an elastic connection bushing, a fiber-reinforced tube bushing, or a rubber bushing. For example, Figure 5 the elastic connection element 60 is shown as a silicone tube, which can, for example, be implemented in four layers. For example, a four-layer silicone tube is very durable and exhibits an operating temperature of -50 °C to 250 °C. In particular, the spiral housing 78 of the heat pump 100 can be attached to the frame 40 using an elastic damper.

[0043] Furthermore, the elastic connection element 60 is preferably implemented as a so-called stop block metal damper, as can be derived, for example, from Figure 8 The stop block metal damper is aging-resistant because the damping is obtained through a twisted wire mesh. No rubber elastic material needs to be used in the stop block metal damper. Figure 8 Different embodiments of the stop block metal damper can be seen in, and since the stop block metal damper is well-known to those skilled in the art, it will not be discussed in detail here.

[0044] Preferably, the heat pump 100 includes a number of decoupling elements, such as at least four decoupling elements. Here, a first decoupling element can be arranged between the intake socket of the compressor 20 and the first spiral housing 78 of the compressor 20. A second decoupling element can be arranged between the spiral housing 78 of the compressor 20 and the intercooler. A third decoupling element can be arranged between the intercooler and the second spiral housing 78 of the condenser 30 or the second or last compressor stage 70-n. A fourth decoupling element can be arranged between the spiral housing 78 and the condenser 30. More or fewer decoupling elements can be provided between the individual components of the heat pump 100 while still complying with the present invention.

[0045] First, the spiral housing 78 of the heat pump 100 must be completely decoupled from the other components of the heat pump 100 to avoid vibration transfer to other components, especially to the tank and the frame 40.

[0046] Preferably, the elastic connecting element 60 is configured such that the free length of the elastic connecting element 60 between the fixed catheter ends is less than or equal to 20 mm. When using a silicone tube or a silicone bushing as shown in Figure 5 , the free length between the elements is 20 mm or 15 mm or less. With a free length of at most 20 mm or 15 mm or less of the silicone tube or the silicone bushing between the sockets, excessive suction caused by negative pressure can be prevented. Alternatively or additionally, an aramid fiber-reinforced tube or bushing can be used. Especially in the case where elevated temperatures and / or negative pressures are formed in the heat pump 100, an aramid fiber-reinforced tube or bushing can be used. In the absence of elevated or reduced temperatures or negative or positive pressures, a tube or a bushing can also be used instead of an aramid fiber-reinforced tube or bushing. As described above, an elastic bushing can be used instead of or in addition to a tube. One or more polyester gaskets can also be used. Preferably, the tube, especially implemented as a cooling tube, includes a rayon cord gasket starting from an ID (inner diameter) of 20. Preferably, the tube is made of EPDM (ethylene propylene diene monomer rubber), and in particular, the tube includes a fabric gasket.

[0047] Preferably, the compressor 20 includes a spiral housing 78 and a drive motor 80 connected to the spiral housing 78, wherein the vibration damper 50 is configured to elastically couple the spiral housing 78 to the evaporator 10, the condenser 30, and / or the frame 40. The elastic coupling includes decoupling vibrations that may be formed especially by the operation of the drive motor 80. For example, the spiral housing 78 can be seen in Figure 2 , where the drive motor 80 is arranged below the explosion-proof barrel.

[0048] Preferably, the vibration damper 50 includes a vibration absorber (vibration tilger, sometimes also referred to as a vibration tuner) 82 arranged at the compressor 20 and is configured to passively or actively reduce the vibrations of the compressor 20 caused by operating the compressor 20. The term "absorber" relates to an inclination device, which has been adopted in technical terms and will be used in this application. For example, Figure 9 shows a passively operated vibration absorber 82, while Figure 10 shows an actively operated vibration absorber 82. As can be derived from Figure 9 , the passive vibration absorber 82 is a system 101 including a spring 102, a damper 103, and a mass 104. Vibration absorbers 82 are an inexpensive and reliable solution for vibration problems because they operate efficiently within their target frequency range and have high robustness. An important advantage is that no pedestals are required. This means that the vibration absorbers 82 can be attached almost anywhere, optimized only with respect to the effectiveness criteria. As Figure 10The active vibration absorber 82 shown in [Figure] also includes an active system 107. The active system 107 may include an actuator, a sensor, a regulator, and / or an auxiliary energy source. The active system 107 may supply energy and / or instructions to the system 101 of the passive vibration absorber 82 to actively cancel vibrations. The active vibration absorber 82 may perform regulation through its actuator, sensor, and regulator as a function of isolating vibrations by the vibration absorber 82.

[0049] Possible fixing points 108 of the absorber 82 at the helical housing 78 or at the motor housing of the drive motor 80 may be derived from Figure 11 In the heat pump 100, a number of passive absorbers 82 or active absorbers 82 may be attached at the compressor 20 or at the helical housing 78 of the compressor 20 to damp vibrations during start-up and shut-down of the compressor 20 and during operation of the heat pump 100 or the compressor 20.

[0050] Preferably, the compressor 20 includes a helical housing 78 and a drive motor 80 connected to the helical housing 78, wherein the vibration absorber 82 is arranged at the helical housing 78 or at the drive motor 80. The vibration absorber 82 may be an active or a passive vibration absorber 82. In Figure 2 、 11 the drive motor 80 is shown as being covered by an explosion-proof barrel 90, i.e., not visible. The drive motor 80 is visible in Figure 1 [Figure].

[0051] Preferably, the heat pump 100 includes a bypass conduit 85 between the evaporator 10 and the condenser 30, wherein the vibration influencer 50 includes at least one elastic connecting element 60 between the bypass conduit 85 and the evaporator 10 or between the bypass conduit 85 and the condenser 30, and / or wherein the bypass conduit 85 is realized as a flexible conduit. A flexible conduit is a flexible duct which can, in particular, be extended or compressed along its length. During installation of the heat pump 100 or during operation of the heat pump 100, it may be advantageous for the bypass conduit 85 to be stretchable or compressible to compensate for tolerances. For example, in Figure 12 [Figure] the bypass conduit 85 between the condenser 30 and the evaporator 10 can be seen. In addition, rubber bushings 109 may be arranged at the bypass input and the bypass output (see Figure 12 [Figure]).

[0052] The bypass conduit 85 may, for example, be realized as a bellows. Figure 13Shows embodiments of different bellows. The bellows are made of different materials with a wavy profile. The standard size range of well-known bellows is from DN 6 to DN 300. The bellows can be used at temperatures from -270 °C to a maximum of 600 °C. The bellows are pressure-resistant and sealed, and for particularly corrosive media can include a PTFE coating. In addition, the bellows can be implemented with different connection fittings. The annular bellows are made of butt-welded pipes, which are mechanically formed into a wavy shape.

[0053] Preferably, the heat pump 100 further includes a free cooling module 92 arranged at the frame 40 (see Figure 2 and 16 ), wherein the vibration actuator 50 includes an elastic damper 94 between the free cooling module 92 and the frame 40. Additionally or alternatively, the heat pump 100 includes an external gas suction device 96, wherein the vibration actuator 50 is configured to decouple the external gas suction device 96 from the frame 40 and / or the condenser 30 in terms of vibration. The external gas suction device 96 and the free cooling module 92 can be seen, for example, in Figure 16 . The free cooling module 92 can be decoupled from the frame 40 by an elastic connection element (such as the elastic damper 94). The free cooling module 92 does not generate vibrations, but it is a large mass that can be excited to vibrate. Regarding the decoupling of the external gas suction, it should be remembered that the external gas suction device 96 itself is not excited to vibrate. However, it is a vibrating element capable of transmitting vibrations.

[0054] Preferably, the compressor 20 includes a burst protection device, which is configured to preferably hold one or more parts of the compressor 20 within the frame 40 in the case of a burst of the compressor 20. In particular, the drive motor 80 or each drive motor 80 includes a burst protection device, which is configured to hold one or more parts of the drive motor 80 substantially in their position, i.e., within the burst protection device, in the case of a burst of the drive motor 80.

[0055] Preferably, the compressor 20 includes a drive motor 80 and a spiral housing 78 arranged at the frame, wherein the burst protection device includes an explosion-proof barrel 90 above the drive motor 80 and / or a capture device 98 at the spiral housing 78 and the frame 40. Alternatively or additionally, the burst protection device includes an explosion-proof barrel 90 above the drive motor 80, wherein the intermediate space between the explosion-proof barrel 90 and the drive motor 80 is filled with a noise damping material 78. The burst protection device may include an explosion-proof barrel 90 and / or a capture device 98. In the case of the explosion-proof barrel 90, the explosion-proof barrel 90 covers the drive motor 80. In the case of a plurality of drive motors 80, each drive motor 80 is covered by its own explosion-proof barrel. Additionally, each spiral housing 78 may include its own capture device configured to protect the corresponding spiral housing 78 from damage by parts of the corresponding drive motor 80 in the event of a burst of the drive motor 80.

[0056] Figure 14 The drive motor 80 of a heat pump without an explosion protection device and the drive motor 80 of a heat pump with an explosion-proof barrel 90 placed above it are shown. In order to dampen noise, a noise damping material, such as a foam material, may be arranged between the drive motor 80 and the explosion-proof barrel 90. Figure 15 A noise damping material in the form of, for example, a foam material is shown. In Figure 15 it, a pyramidal foam material made of Basotect G+ is shown, which has a base-pyramid ratio of 1:2. According to Figure 15 the noise damping material includes a fine open-cell structure. Additionally, the fire resistance of the noise damping material according to DIN 4102 B1 is almost non-combustible and complies with FMVSS 302 and UL 94 V0+HF1. The thermal conductivity of the noise damping material is basically 0.035 W / mK. The noise damping material can be used in the temperature range from -40 °C to +150 °C and includes a bulk density of basically 9 kg / m 3 ³.

[0057] Figure 17Shows a sectional view of the heat pump 100. In this sectional view, the spiral housing 78 can be seen, above which a capture device 98 is arranged. The safety capture device 98 is arranged between the spiral housing 78 and the base 79 connected to the frame 40. The capture device 98 can be comprised of an elastic damper 94, preferably as a wire rope loosely introduced into the elastic damper 94. In the case of an impeller burst, i.e., in the case of a malfunction during operation, the impeller will tilt relative to the spiral housing 78 or transfer torque to the spiral housing 78. The result will be that the elastic connecting element 60, preferably the elastic damper 94, will tear, and the spiral housing 78 will impact back and forth or rotate in its mounting, which may pose a danger to bystanders. The capture device 98 is provided to prevent this. The capture device 98 can be, for example, a wire rope that is connected to the spiral housing or the frame, and which is preferably loosely introduced into the elastic damper 94. As Figure 17 shown, the capture device 98 can also be implemented as a pull-out member that is connected to the spiral housing 78 via the elastic damper 94 using its base 79. In the case of a burst, the torque acting on the spiral housing 78 is captured and introduced into the frame 40. Thus, there will be no uncontrolled swinging of the spiral housing 78 in its fittings. The capture device 98 can also be connected between the spiral housing 78 and the base 79 as a "loose screw".

[0058] Figure 18 Shows another aspect of the present invention, relating to a method for operating the heat pump 100. The method 180 for operating the heat pump 100 includes, in step 180, providing the heat pump 100, which includes: an evaporator 10 for evaporating an operating liquid to obtain an operating vapor; a compressor 20 for compressing the operating vapor to obtain a compressed operating vapor; a condenser 30 for condensing the compressed operating vapor; and a frame 40 to which the evaporator 10, the condenser 30, and / or the compressor 20 are attached. The method includes step 181: decoupling the compressor 20 from the evaporator 10, the condenser 30, and / or the frame 40 in terms of vibration, and / or actively or passively reducing the vibration of the compressor 20. To decouple the vibration, the method uses, in step 182, one or more elastic connecting elements 60 comprised of a vibration influencer 50, as described in connection with the heat pump 100. To improve the protection of the heat pump during operation, the method includes arranging a burst protection device, as described herein in connection with the heat pump 100. In other words, the features described in the context of the heat pump 100 can also be understood as method steps for arranging and operating the heat pump 100.

[0059] Figure 19Shows another aspect of the present invention, which relates to a method 190 for manufacturing a heat pump 100. The method for manufacturing a heat pump 100 includes, in step 190, providing a heat pump 100, which includes: an evaporator 10 for evaporating an operating liquid to obtain an operating vapor; a compressor 20 for compressing the operating vapor to obtain a compressed operating vapor; a condenser (or liquefier) 30 for condensing the compressed operating vapor; and a frame 40 to which the evaporator 10, the condenser 30, and / or the compressor 20 are mounted. The method includes step 192: forming a vibration damper 50 to decouple the compressor 20 from the evaporator 10, the condenser 30, and / or the frame 40 in terms of vibration, and / or actively or passively reducing the vibration of the compressor 20. To decouple the vibration, the method uses one or more elastic connection elements 60 included in the vibration damper 50, as described in connection with the heat pump 100. To improve the protection of the heat pump during operation, the method includes arranging a burst protection device, as described in connection with the heat pump 100. In other words, the features described in the context of the heat pump 100 can also be understood as method steps for arranging and operating the heat pump 100.

[0060] One advantage of the invention described herein is that the spiral housing 78 including the drive motor 80 is decoupled from the tanks of the evaporator, compressor, and condenser, such that vibrations formed during the operation of the heat pump 100 due to the drive motor are not transmitted (or only to a reduced extent) to other components of the heat pump. In particular, the spiral housing 78 may produce resonance, for example, the tanks of the evaporator or compressor represent resonators. Through the present invention, the vibration damper 50 can reduce the vibration to prevent vibration transmission.

[0061] Another advantage of the invention described herein is that the compressor 20 can be decoupled from its tank through a fiber-reinforced tube / rubber bushing, and decoupling can also be performed between the compressor 20 and the frame 40 of the heat pump. The rubber bushing can also compensate for manufacturing tolerances, making the manufacture of the heat pump 100 easier. In addition, by additionally installing additional absorbers, the vibration transmission of the drive motor 80 can be reduced, especially prevented.

[0062] In particular, through the invention described herein, vibration and noise decoupling between the compressor and the tank (resonator) can be achieved, and at the same time, temperature decoupling between individual components of the heat pump 100 can be achieved.
