Description

Technical Field

[0001] This utility model relates to a water module and a heat pump system, and more specifically to an installation structure for a water module and a heat pump system including the water module. Background Technology

[0002] Previously, air source heat pump units with refrigerant-water heat exchangers (hereinafter referred to as "water modules") were typically mounted on indoor walls by connecting the back panel of the indoor unit to the wall.

[0003] To facilitate the provision of leverage points during installation, current water modules have recessed handles on both sides (side panels) of the outer casing for hand gripping, or external handles on the back panel of the outer casing near the sides for hand gripping.

[0004] Setting recessed handles on the side panels of the casing would complicate the structure of the water module's casing, while setting external handles near the sides of the back panel of the casing would similarly complicate the internal structure of the water module's casing.

[0005] Therefore, how to simplify the arrangement of the handle, especially how to place the handle inside the housing without complicating the housing structure and without interfering with other components inside the housing, has become an urgent technical problem to be solved. Utility Model Content

[0006] This utility model is made to solve the problems of the prior art. Its purpose is to provide a water module that does not require a handle to be set on the outer surface (side or back plate) of the shell, thereby avoiding the complexity of the shell structure and simplifying the arrangement of the handle inside the shell, without interfering with other components inside the shell.

[0007] Another objective of this invention is to provide a heat pump device including the aforementioned water module.

[0008] To achieve the above objectives, this utility model provides a water module, including a housing, inside which is a piping assembly consisting of refrigerant piping and water piping, and a refrigerant that allows heat exchange between the refrigerant flowing through the refrigerant piping and the water flowing through the water piping.

[0009] - A water-heat exchanger, characterized in that the refrigerant-water-heat exchanger is disposed in the middle part inside the housing and is fixed to the housing by a mounting bracket, the mounting bracket having:

[0010] A first fixing plate, which is opposite to the mounting surface of the housing for mounting the refrigerant-water heat exchanger and fixes the refrigerant-water heat exchanger through its inner surface, has a handle formed on its outer surface.

[0011] As described above, by using a mounting bracket that secures the refrigerant-water heat exchanger via its inner surface to provide the handle, a rational internal layout is possible, resulting in a simple structure and miniaturization. Furthermore, since the handle is located inside the water module's housing, there is no need to install a handle on the outer surface (side or back panel) of the housing, thus avoiding any structural complexity. Additionally, because the handle is positioned on the outer surface of the first mounting plate of the bracket, it facilitates gripping (especially easier than when the handle is on the back panel) and application of force by the operator.

[0012] Furthermore, based on the configuration described above, since the handle is located in the middle of the height direction within the water module 100, close to the center of gravity of the water module, only one handle is needed to facilitate the effort required for movement, making it convenient for single-person operation and reducing construction difficulty.

[0013] Furthermore, based on the configuration described above, since the handle is mounted on the first fixed plate of the mounting bracket opposite to the back plate of the housing, it will not interfere with other components such as the piping assembly inside the housing. The structure is simple, which is conducive to miniaturization and easy to grip.

[0014] Preferably, in this invention, the outer casing includes a back plate, and the first fixing plate is opposite to the inner side of the back plate inside the outer casing and is fitted to the refrigerant-water heat exchanger, thereby fixing the refrigerant-water heat exchanger to the mounting surface on the outer casing. In this case, a first fixing hole can be provided on the first fixing plate, and a corresponding fixing hole can also be provided at the corresponding position of the refrigerant-water heat exchanger. The first fixing plate of the fixing frame and the refrigerant-water heat exchanger are fixed together by fastening components.

[0015] As described above, the first fixing plate of the mounting bracket can press the refrigerant-water heat exchanger against the mounting surface of the housing (back plate) for mounting the refrigerant-water heat exchanger. Furthermore, by fastening the first fixing plate of the mounting bracket to the refrigerant-water heat exchanger using fastening members, significant displacement of the refrigerant-water heat exchanger can be prevented, ensuring stable fixation of the refrigerant-water heat exchanger and a robust overall structure.

[0016] In this utility model, preferably, the fixing frame has a second fixing plate and a third fixing plate, the second fixing plate and the third fixing plate are respectively connected to two sides in the horizontal direction of the first fixing plate, and the second fixing plate and the third fixing plate are respectively fixed to the back plate so that the first fixing plate further presses the refrigerant-water heat exchanger against the mounting surface of the outer shell.

[0017] Although it is preferable for the mounting bracket to have both a second and a third fixing plate.

[0018] However, even with only a second or third fixing plate, the basic function of the mounting bracket—fixing the refrigerant-water heat exchanger to the casing—can still be achieved to some extent. However, because the bracket is only fixed to the inner side of the back panel within the casing by this single fixing plate, the operator might deform it when gripping the water module with the handle, potentially causing the bracket (along with the refrigerant-water heat exchanger) to be pulled down. In this case, if the fixation of the second or third fixing plate to the inner side of the back panel is sufficiently secure, or if the reliability of the fixation is improved by fixing the refrigerant-water heat exchanger to the inner side of the back panel (and further, by fixing the first fixing plate to the refrigerant-water heat exchanger as well), thus preventing deformation or even pull-down, then having only a second or third fixing plate is not impossible.

[0019] As described above, by relying on the fixation of the second and third fixing plates to the inner side of the back plate, regardless of whether the handle is installed on the second fixing plate side or the third fixing plate side, the force applied to the handle can be more dispersed to the fixing parts of the second and third fixing plates and the inner side of the back plate inside the shell, which can greatly reduce or even avoid the deformation or even pull-down of the fixing frame due to excessive force.

[0020] Furthermore, in this invention, it is preferred that the handle is arranged along the height direction of the first fixing plate.

[0021] As described above, the water module can be easily moved vertically by the operator.

[0022] More preferably, flanges are provided on two sides of the first fixing plate in the height direction, respectively, away from the refrigerant-water heat exchanger, and the handle is formed on the flanges of the first fixing plate. Furthermore, the handle has two connecting portions fixedly connected to the two flanges of the first fixing plate, and a handle portion formed between the two connecting portions. Additionally, the handle portion further has a pair of gripping surfaces extending away from the refrigerant-water heat exchanger and facing each other, with curved portions formed on each of the pair of gripping surfaces, each curving in a direction approaching each other.

[0023] As described above, the handle has a simple structure, is easy to install, and ensures sufficient installation strength. Furthermore, the pair of facing gripping surfaces on the handle facilitates gripping and prevents the operator from slipping. Moreover, the curved bends forming on the gripping surfaces prevent the operator from getting their hands hurt or being cut by sharp edges when applying force. The flanged handle design ensures that the fasteners have sufficient clearance and will not interfere with the refrigerant-water heat exchanger or its surrounding piping.

[0024] Furthermore, in a preferred embodiment of this invention, the water module further includes a wall-mounting panel, and a hook that mates with the wall-mounting panel is provided on the outer side of the back panel of the outer casing. Additionally, an observation hole is provided on the back panel, and the observation hole is located near the hook.

[0025] As described above, the wall-mounted panel enables pre-positioning and pre-installation. The panel is pre-installed on the wall or other mounting surface, and the water module housing is then hung on the panel using hooks. This reduces the need for operators to hold the heavy water module for extended periods to determine its installation position. Furthermore, the observation hole allows for a view of the back panel of the housing from the front. Positioning the observation hole near the hooks facilitates observation of the hook-wall-mounted panel's fit, enabling single-person operation and reducing construction difficulty.

[0026] In this invention, the handle can be integrally formed with the fixing frame or separately formed with the fixing frame and assembled together. The structure is simple and can ensure the strength of the handle.

[0027] In addition, this utility model also provides a heat pump system, wherein the heat pump system includes the aforementioned water module. Attached Figure Description

[0085] The following is for reference Figures 1 to 5 The water module 100 of this utility model will be described in detail below. In these figures, Figure 1 This is a schematic diagram showing the internal layout of the outer casing 110 of the water module 100 of this utility model from the front. The front panel and two side panels of the casing are omitted from the diagram. Figure 2 This is a schematic diagram showing the outer casing 110 (back plate 111) of the water module 100 of this utility model from the back. Figure 3 Installed from the right front Figure 1 The diagram shows an enlarged view of the mounting bracket 300 inside the outer casing 110 of the water module 100. Figure 4 Installed from the left front Figure 1 The diagram shows an enlarged view of the mounting bracket 300 inside the outer casing 110 of the water module 100. Figure 5 It is installed in Figure 4 A partial enlarged view of the handle portion 342 of the handle 340 on the fixture 300 shown.

[0086] The water module 100 of this utility model is installed on the wall by means of a back plate 111 being hung on the wall. Figure 1 The orientation for mounting is shown. The housing 110 of the water module 100 includes a front panel (not shown), a back panel 111, left and right side panels (not shown), a bottom panel 112, and a top panel 113.

[0087] Additionally, inside the housing 110 of the water module 100, such as Figure 1 As shown, the system includes a piping assembly 120 consisting of a refrigerant piping 121 (a refrigerant circuit connected to an outdoor unit not shown) and a water piping 122 (the water piping 122 connects to the underfloor heating coil to form a closed water circuit); a refrigerant-water heat exchanger 130 for exchanging heat between the refrigerant flowing through the refrigerant piping 121 and the water flowing through the water piping 122; an expansion tank 140 for absorbing the volume expansion caused by the rise in water temperature in the closed water circuit; and an electrical control box 150 for controlling the various electrical components of the water module 100. The refrigerant-water heat exchanger 130 is either a plate heat exchanger or a coaxial heat exchanger.

[0088] In addition, Figure 1In this configuration, the refrigerant piping 121 has a first refrigerant piping 121A connected to the upper end of the refrigerant-water heat exchanger 130 (which is the inlet end when the refrigerant flows in one direction, such as during heating, and the outlet end when the refrigerant flows in the opposite direction, such as during defrosting), and a second refrigerant piping 121B connected to the lower end of the refrigerant-water heat exchanger 130 (which is the outlet end when the refrigerant flows in one direction, such as during heating, and the inlet end when the refrigerant flows in the opposite direction, such as during defrosting). Additionally, in... Figure 1 In the middle, the water pipe 122 has a first water pipe 122A connected to the lower end (e.g., the inlet end) of the refrigerant-water heat exchanger 130 and a second water pipe 122B connected to the upper end (e.g., the outlet end) of the refrigerant-water heat exchanger 130.

[0089] specific-

[0090] like Figure 2 As shown, the water module 100 of this utility model also includes a wall-mounted panel 200, which is pre-installed on the wall. Hooks 111a1 that cooperate with the wall-mounted panel 200 are provided on the outer side 111a of the back plate 111 of the outer casing 110. The hooks 111a1 are formed by folding a portion of the back plate 111 outwards, or they can be independent hooks 111a1 fixedly connected to the back plate 111. Furthermore, depending on installation needs, there can be two or more hooks 111a1, and the wall-mounted panel 200 is provided with mounting portions matching the number of hooks 111a1.

[0091] In addition, such as Figure 2 As shown, an observation hole 111b is provided on the back panel 111, which allows the view behind the back panel 111 of the housing 110 to be seen from the front. By placing the observation hole 111b near the hook 111a1, it is convenient to observe the positions of the hook 111a1 and the wall-mounted plate 200, making it easy for operators to quickly assemble the hook 111a1 with the wall-mounted plate 200 to achieve the pre-installation of the water module 100.

[0092] In addition, in the water module 100 of this utility model, such as Figure 1 As shown, the refrigerant-water heat exchanger 130 is disposed in the middle part of the housing 110 (more specifically, the middle part in the height direction) and is fixed to the housing 110 by the mounting bracket 300.

[0093] More specifically, such as Figure 3 and Figure 4As shown, the mounting bracket 300 includes: a first mounting plate 310 that is opposite to the inner side 111c of the back plate 111 inside the housing 110 (more precisely, the mounting surface of the refrigerant-water heat exchanger 130) and is fitted and fixed to the refrigerant-water heat exchanger 130. To ensure a secure fit, the mounting plate can be tightly attached to the refrigerant-water heat exchanger 130; and a second mounting plate 310 that is connected to two horizontally oriented sides (first opposing sides) of the first mounting plate 310 and fixed to the inner side 111c of the back plate 111 inside the housing 110. The fixing plate 320 and the third fixing plate 330 are used to fix the bracket 300 to the refrigerant-water heat exchanger 130 by means of the first fixing plate 310 to push the refrigerant-water heat exchanger 130 towards the refrigerant-water heat exchanger 130 mounting surface on the back plate 111, and to fix the bracket 300 to the back plate 111 inside the housing 110 by means of the second fixing plate 320 and the third fixing plate 330 to further press the refrigerant-water heat exchanger 130 against the refrigerant-water heat exchanger 130 mounting surface on the back plate 111 by means of the first fixing plate 310.

[0094] like Figure 3 As shown, the first fixing plate 310 is in close contact with the refrigerant-water heat exchanger 130, pressing the refrigerant-water heat exchanger 130 against its mounting surface. Preferably, a first fixing hole 311 is provided on the first fixing plate 210, and a corresponding fixing hole (not shown) is also provided at the corresponding position on the refrigerant-water heat exchanger 130, so that the first fixing plate 310 of the fixing bracket 300 and the refrigerant-water heat exchanger 130 can be fixed together using fastening components such as screws.

[0095] In addition, in this utility model, the second fixing plate 320 is as follows: Figure 3The first fixing plate 320 is connected to the right side of the first fixing plate 310 and fixed to the inner side 111c of the back plate 111 inside the housing 110. The third fixing plate 330 is connected to the left side of the first fixing plate 310 and fixed to the inner side 111c of the back plate 111 inside the housing 110. Those skilled in the art should understand that although it is preferred for the fixing bracket 300 to have both the second fixing plate 320 and the third fixing plate 330, having only the second fixing plate 320 or the third fixing plate 330 can also achieve the basic function of the fixing bracket 300 to a certain extent, that is, to fix the refrigerant-water heat exchanger 130 to the housing 110. However, since the fixing relies solely on the second fixing plate 320 or the third fixing plate 330 to the inner side 111c of the back plate 111 inside the housing 110, the fixing bracket 300 may deform due to force when the operator grips the water module 100 with the handle 340, and the fixing bracket 300 (along with the refrigerant-water heat exchanger 130) may even be pulled down. In this case, if the fixing relying solely on the second fixing plate 320 or the third fixing plate 330 to the inner side 111c of the back plate 111 is sufficiently secure, or if the reliability of the fixing is improved by fixing the refrigerant-water heat exchanger 130 to the inner side 111c of the back plate 111 (and further, fixing the first fixing plate 310 to the refrigerant-water heat exchanger 130), thus preventing the fixing bracket 300 from deforming or being pulled down, then it is not impossible for the fixing bracket 300 to have only the second fixing plate 320 or the third fixing plate 330.

[0096] In this invention, the second fixing plate 320 and the third fixing plate 330 are tightly attached to the two opposite sides (right side 131A, left side 131B) of the refrigerant-water heat exchanger 130 from opposite sides (right side and left side). Furthermore, the second fixing plate 320 and the third fixing plate 330 each have folded edges 321 and 331, respectively, with second fixing holes 322 and third fixing holes 332 respectively formed on the folded edges 321 and 331. Corresponding fixing holes (not shown) are also formed at corresponding positions on the inner side 111c of the back plate 111 inside the outer casing 110, allowing the second fixing plate 320 and the third fixing plate 330 of the fixing bracket 300 to be fixed together with the back plate 111 inside the outer casing 110 using screws or other fastening components. In this invention, the second fixing plate 320 and the first fixing plate 310 are integrally formed, thus simplifying the structure of the fixing bracket 300 and making installation convenient. In addition, the third fixing plate 330 is fixed to the side of the first fixing plate 310. Specifically, the side of the first fixing plate 310 has a flange that is away from the refrigerant-water heat exchanger 130. The third fixing plate 330 can be connected to the flange using fastening components such as screws, which facilitates subsequent maintenance and avoids collision interference to the surrounding piping group 120 when the fixing bracket 300 is installed or removed.

[0097] In addition, in this utility model, such as Figure 3 As shown, a handle 340 is formed on the first fixing plate 310. More specifically, flanges 312, which are away from the refrigerant-water heat exchanger 130, are respectively provided on two sides (second opposite sides) of the first fixing plate 310 in a height direction different from the first opposite side. The handle 340 is formed on the flanges 312 of the first fixing plate 310.

[0098] like Figure 5As shown, the handle 340 has two connecting portions 341 fixedly connected to two flanges 312 of the first fixing plate 310, and a handle portion 342 formed between the two connecting portions 341. More specifically, each of the two connecting portions 341 also has a flange 341a, and fixing holes are provided on both flanges 312 of the first fixing plate 310 and on the flanges 341a of each of the two connecting portions 341, so that the connecting portions 341 of the handle 340 can be fixed together with the first fixing plate 310 of the fixing frame 300 using fastening components such as screws. In addition, the handle portion 342 has a pair of gripping surfaces 342a extending away from the refrigerant-water heat exchanger 130 and facing each other, and each pair of gripping surfaces 342a has a curved portion 342b that bends toward each other in a direction closer to each other. In addition, the handle 340 can also be fixed to the first fixing plate 310 by snap-fit. Furthermore, the handle 340 is positioned on the side of the first fixing plate 310 closer to the third fixing plate 330, and the handle portion 342 is inclined toward the center of the first fixing plate 310, so that the handle portion 342 can be closer to the center of gravity of the water module 110, thus balancing the force.

[0099] As described above, by using the mounting bracket 300 that secures the refrigerant-water heat exchanger 130 to install the handle 340, a reasonable internal layout is possible, resulting in a simple structure and miniaturization. Furthermore, since the handle 340 is located inside the housing 110 of the water module 100, there is no need to install a handle on the outer surface (side or back panel) of the housing, thus avoiding any complexity to the housing structure.

[0100] Furthermore, according to the configuration described above, since the handle 340 is located in the middle part of the height direction inside the water module 100, close to the center of gravity of the water module 100, it is convenient to exert force when moving by providing only one handle 340.

[0101] Furthermore, according to the configuration described above, since the handle 340 is set on the first fixing plate 310 of the fixing frame 300 opposite to the back plate 111 of the housing 110, it will not interfere with other components such as the piping assembly 120 inside the housing 110. The structure is simple, which is conducive to miniaturization and easy to grip.

[0102] Next, refer to Figure 6 The heat pump system 1 of this utility model will be described, wherein...

[0103] Figure 6 This is a schematic circuit diagram of a heat pump system 1 including the water module 100 of this utility model.

[0104] In addition, the heat pump system 1 of this utility model includes an air conditioner outdoor unit 10, the aforementioned water module 100, and a user-end water system 20. The air conditioner outdoor unit 10 is connected to the water module 100 through a gas pipe P1 and a liquid pipe P2. An electronic expansion valve V1 of the water module is connected between the liquid pipe P2 of the air conditioner outdoor unit 10 and the water module 100. The inlet and outlet of the water module 100 are connected to the user-end water system 20 through pipelines.

[0105] The heat pump system 1 may also include one or more indoor air conditioning units 30. The outdoor air conditioning unit 10 is connected to one or more indoor air conditioning units 30 through gas piping P1 and liquid piping P2. An electronic expansion valve V2 of the indoor air conditioning unit is connected between the liquid piping P2 of the outdoor air conditioning unit 10 and the heat exchanger 31 of the indoor air conditioning unit 30.

[0106] The user-end water system 20 includes at least a floor heating coil 21, which heats the indoor space.

[0107] Other advantages and modifications will readily occur to those skilled in the art. Therefore, more broadly, this invention is not limited to the specific details and representative embodiments shown and described herein. Thus, modifications can be made without departing from the spirit or scope of the overall inventive concept as defined by the appended claims and their equivalents.

[0108] In the foregoing description, the case in which the connecting part 341 of the handle 340 is fixed together with the first fixing plate 310 of the fixing frame 300 by using fastening components such as screws, that is, the handle 340 and the fixing frame 200 are formed separately and then assembled, was described as an example. However, the present invention is not limited to this, and the handle 340 may also be integrally formed on the fixing frame 200.
