[0035] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0036] The present application provides a heat pump system, which can be a ground source heat pump, an air source heat pump, or an air-cooled heat pump, but is not limited thereto. For ease of explanation, the following heat pump systems are all traditional air source heat pumps.

[0037] The heat pump system of this embodiment includes an outdoor unit and a hydraulic module 100. The outdoor unit is used to exchange heat with the external environment, while the hydraulic module 100 is used to exchange heat between the refrigerant in the refrigerant pipe and the water in the water pipe, thereby heating or cooling the water, thereby outputting water at a set temperature and delivering it to a water storage device such as a water tank, or to a heat release device such as a floor heating pipe or radiator.

[0038] Among them, as mentioned in the background technology, the hydraulic module 100 includes a water pump, valves, a filter (also known as a filter assembly 20), a constant pressure water supply device, a water pump control electrical cabinet, a box 10 and some pipeline structures 30. So many structures are arranged in one box 10, which will make the structural layout of the entire box 10 more messy, thereby affecting the user's observation of the filtering condition of the filter and the regular replacement of the filter element.

[0039] See also Figure 1 、 Figure 3 as well as Figure 5 An embodiment of the present application provides a hydraulic module 100 , including a box body 10 , a filter assembly 20 , a buffer water tank 40 and an expansion tank 50 .

[0040] The box body 10 serves as the appearance component of the entire hydraulic module 100. It not only includes the internal filter assembly 20, the buffer water tank 40 and the expansion valve for protecting the interior, but also enables the entire hydraulic module 100 to be an integrated design, which greatly saves the floor space of the machine room and improves space utilization. The box body 10 includes a first side panel 11 and multiple second side panels 12. The first side panel 11 and the multiple second side panels 12 are enclosed to form an installation cavity 10a, wherein at least one second side panel 12 can serve as a panel of the entire box body 10, and the second side panel 12 can be rotated on the adjacent first side panel 11 or second side panel 12 by means of a rotating shaft. In this way, the structure inside the installation cavity 10a can be exposed or covered by opening and closing the second side panel 12.

[0041] The filter assembly 20 is mainly used to filter municipal water, and may include a magnetic filter 21 and a soft water filter 22. Figure 2 As shown, the magnetic filter 21 is primarily used to remove iron filings, iron powder, and other ferromagnetic impurities from fluids (including liquids, slurries, or gases). Its powerful adsorption capacity can capture ferromagnetic contaminants at the micron level, maintaining excellent filtration even at high flow rates. The soft water filter 22 is primarily designed to remove calcium and magnesium ions (the main components of scale formation) from water, thereby reducing water hardness.

[0042] By reducing the hardness of water, the soft water filter 22 can reduce the formation of scale, protect household appliances (such as water heaters, washing machines, etc.) from scale erosion, and extend the service life of the equipment.

[0043] The water inlet of the buffer water tank 40 is at the top and the water outlet is at the bottom. Temperature zoning can be achieved according to the different water temperatures of the inlet and outlet. According to the usage of the terminal (heating end), the excess heat source can be stored in the buffer water tank 40, and the heat source of the buffer water tank 40 can also be extracted to participate in the terminal temperature regulation. The terminal returns water to the bottom of the buffer water tank 40, and at the same time, the outdoor unit return water is also taken from the buffer water tank to achieve dynamic balance.

[0044] The expansion tank 50 is mainly used to balance the pressure, for example, to prevent the internal pressure of the buffer water tank 40 from being too high, which may damage the equipment.

[0045] In the examples of this application, please refer to Figure 1-2A first inspection port 11a is provided on the first side panel 11, and the filter assembly 20 is arranged adjacent to the first side panel 11, and the filter assembly 20 is arranged opposite to the first inspection port 11a. In this way, it is convenient for the user to observe the operation of the filter assembly 20 through the first inspection port 11a. After entering the installation cavity 10a from the first inspection port 11a, the maintenance personnel can directly and conveniently access the filter assembly 20 without moving or disassembling other components, which is convenient for replacing the filter element and cleaning the filter assembly 20.

[0046] It can be understood that when the filter assembly 20 includes a magnetic filter 21 and a soft water filter 22, the magnetic filter 21 and the soft water filter 22 can be arranged in a row along the height direction of the corresponding first side plate 11, or can be arranged in a row along the width direction of the corresponding first side plate 11. When the filter assembly 20 includes multiple filters, the filters can also be distributed at intervals along the height direction and width direction of the corresponding first side plate 11 at the same time. In this way, when the filter assembly 20 includes multiple filters, it is also convenient to inspect and repair the multiple filters or replace the filter elements of the multiple filters.

[0047] For further information, please refer to Figure 2 In order to prevent foreign matter such as dust and water from entering the installation cavity 10a through the first inspection port 11a, an inspection panel 111 is provided on the first side panel 11. The inspection panel 111 is installed at the first inspection port 11a to cover the first inspection port 11a. In order to facilitate the user to observe the operation of the internal filter assembly 20 or the operation of other components, the inspection panel 111 has a first visual area 111a, and the first visual area 111a is arranged opposite to the filter assembly 20.

[0048] In some embodiments, the inspection panel 111 is made of a transparent or translucent material, such as transparent plastic, glass, or a special transparent alloy, to ensure that the status of the filter assembly 20 can be clearly observed while covering the first inspection port 11 a.

[0049] In some possible embodiments, the inspection panel 111 may include a mounting plate and transparent plastic, glass or special transparent alloy, etc. The mounting plate facilitates the installation of transparent plastic, glass or special transparent alloy, etc., and the mounting plate is also convenient for installation on the first side panel 11. In this embodiment, there is no restriction on this, and it is set according to actual conditions.

[0050] The inspection panel 111 can be fixed to the first side panel 11 by means of bolts, screws, etc., or can be connected to the first side panel 11 in a movable manner.

[0051] Fixing methods such as bolts and screws are usually used in conjunction with sealing gaskets or sealants to form a tight sealing layer between the inspection plate 111 and the first side panel 11, effectively preventing foreign matter such as water and dust from entering the installation cavity 10a, thereby ensuring the sealing and safety of the system.

[0052] The embodiment of the present application adopts a movable connection method, which enables the inspection panel 111 to be easily opened and closed and can be operated without the use of tools, thereby greatly improving the convenience and efficiency of maintenance.

[0053] During actual use, the user can directly observe the filtering condition of the filter assembly 20 through the first visual area 111a on the maintenance panel 111. When a fault is found or the filter element needs to be replaced, the maintenance panel 111 can be quickly opened.

[0054] Specifically, in one embodiment, the access panel 111 is movable relative to the first side panel 11 within a movable plane. Because the access panel 111 can move within the movable plane, no additional fixed space is required for maintenance operations. This design helps maximize the use of installation space, making the entire system more compact and efficient.

[0055] Based on the above, the inspection panel 111 moves relative to the first side panel 11 in a movable plane, which can be specifically manifested as: the inspection panel 111 moves relative to the first side panel 11 in a translational manner in the movable plane, or the inspection panel 111 moves relative to the first side panel 11 in a rotational manner in the movable plane.

[0056] When the access panel 111 moves in a translational manner relative to the first side panel 11 in the movable plane, this can be achieved through a slide rail system, that is, the access panel 111 is connected to the first side panel 11 through the slide rail system. The slide rail system generally includes a track fixed to the first side panel 11 and a slider installed at the bottom of the access panel 111. The slider slides along the track to achieve translation of the access panel 111 in the horizontal direction (or within the movable plane).

[0057] The sliding access panel 111 does not occupy additional vertical space when opened, and is particularly suitable for environments with limited space. The access panel 111 can be opened and closed by simple push-pull actions without the need for complicated operating steps. The slide rail system provides stable support for the access panel 111, avoiding shaking or tilting that may occur during the opening and closing process.

[0058] In addition, in order to ensure the stability of the access panel 111, the slide rail system may also be equipped with a locking mechanism for fixing the access panel 111 when it is in the closed position. The locking mechanism can ensure that the access panel 111 is firmly fixed in the closed state to prevent accidental opening that may cause dust, water and other external impurities to enter the installation cavity 10a.

[0059] When the inspection panel 111 moves relative to the first side panel 11 in a rotational manner in the movable plane, that is, the inspection panel 111 rotates around an axis perpendicular to the corresponding first side panel 11, since the inspection panel 111 rotates around an axis perpendicular to the first side panel 11, it can be fully opened without blocking any line of sight or space, thereby maximizing the exposure of component areas that require inspection or maintenance, such as the filter assembly 20, which enables maintenance personnel to more easily approach and operate internal components, thereby improving inspection efficiency.

[0060] Furthermore, in the closed state, the rotatable access panel 111 is closely attached to or parallel to the first side panel 11 , does not occupy additional space, and is suitable for environments with limited space, such as the interior of compact mechanical equipment or a small room.

[0061] In another embodiment of the present application, the inspection panel 111 moves in a flipping manner relative to the first side panel 11, that is, the inspection panel 111 can move away from or closer to the installation cavity 10a relative to the first side panel 11. The design of the flip-type inspection panel 111 enables maintenance personnel to easily open and close the inspection panel 111 without using complicated tools or performing tedious operations, which greatly improves the convenience of inspection and maintenance, and also makes it easier for users to understand the opening and closing methods of the inspection panel 111 more intuitively.

[0062] In a specific embodiment, one or more pairs of hinges or hinges are installed on the first side panel 11 , and these hinges or hinges are fixed to the first side panel 11 and the access panel 111 to ensure that the access panel 111 can be flipped around them.

[0063] The access panel 111 is designed to be flippable around the axis of the hinge or hinge. When the access panel 111 needs to be opened, it can be flipped to a certain angle along the axis of the hinge by manual operation (such as pushing, pulling, lifting, etc.), thereby exposing the components in the installation cavity 10a.

[0064] It can be understood that there can be one or more inspection panels 111. In some other embodiments of the present application, there can be two inspection panels 111, and the first inspection port 11a can be opened in a double-opening manner to reduce the space occupied by a single inspection panel 111 and improve the flexibility of opening and closing the inspection panel 111.

[0065] Specifically, the magnetic filter 21 and the soft water filter 22 both include a shell and a filter element. The shell of the magnetic filter 21 has a second visible area, which is arranged opposite to the filter element of the magnetic filter 21. The shell of the soft water filter 22 has a third visible area, which is arranged opposite to the filter element of the soft water filter 22.

[0066] The housings of the magnetic filter 21 and the soft water filter 22 are made of transparent or translucent materials, such as transparent glass or transparent plastic, so that the internal conditions can be observed.

[0067] Of course, it can also be understood that specific positions of the magnetic filter 21 housing and the soft water filter 22 housing are made of transparent or translucent materials, and this area directly corresponds to the position of the filter element. In this way, the user can directly observe the ferromagnetic impurities adsorbed on the filter element through the first visual area 111a on the inspection panel 111 and the second visual area on the housing, thereby determining whether the filter element needs to be cleaned.

[0068] The filter element (such as a pre-filter) or resin column (for ion exchange) is fixed inside the soft water filter 22 housing to ensure that the fluid can be effectively treated when passing through. The third visual area allows the user to observe whether the filter element is blocked or the adsorption status of the resin column, and to determine whether the filter element needs to be replaced or the resin needs to be regenerated.

[0069] The second and third viewing areas provide real-time filter status monitoring, helping to promptly detect and address filter blockage issues before affecting filtration effectiveness and equipment performance.

[0070] In addition, users can reasonably arrange cleaning time based on the filter element conditions observed in the visual area, reduce unnecessary downtime, and improve equipment utilization.

[0071] Understandably, see Figure 3-4 The box body 10 also has an upper cover plate 13 and a lower cover plate (obscured in the figure), which are respectively connected to the opposite ends of multiple second side plates 12. The upper cover plate 13 and the lower cover plate work together with the first side plate 11 and the second side plate 12 to enclose the entire installation cavity 10a.

[0072] In an embodiment of the present application, the expansion tank 50 is located on the side of the buffer water tank 40 close to the upper cover plate 13. In order to ensure the stability of the system water pressure, it is necessary to adjust the pressure of the expansion tank 50. In an embodiment of the present application, a second inspection port 13a is provided on the upper cover plate 13, and the expansion tank 50 has an inflation port 50a. The inflation port 50a can be provided corresponding to the second inspection port 13a. In this way, the user can observe the inflation port 50a through the second inspection port 13a.

[0073] Optionally, the second inspection port 13a can be in a circular, square, polygonal, or other shape, and the specific shape of the second inspection port 13a is not limited. Preferably, the second inspection port 13a is in a circular shape so that the second inspection port 13a can be adapted to the pipe on the detection equipment and facilitate the insertion of the pipe into the second inspection port 13a.

[0074] When it is necessary to detect the pressure of the expansion tank 50 or to inflate the expansion tank 50, the detection equipment can be directly connected to the inflation port 50a on the expansion tank 50 through the second inspection port 13a to detect the pressure of the expansion tank 50, and the external gas source can also be connected to the inflation port 50a on the expansion tank 50 through the second inspection port 13a to restore the pressure of the expansion tank 50 to the default value set at the factory. Therefore, the staff can directly perform detection operations or inflation operations on the expansion tank 50 through the second inspection port 13a without removing the upper cover plate 13, and can conveniently detect or adjust the pressure of the expansion tank 50.

[0075] For further information, please refer to Figure 3-4 The box body 10 can further include a protective plate 14 , which can be movably disposed on the outer side of the box body 10 , and the protective plate 14 can be used to open or close the second inspection port 13 a .

[0076] Optionally, the protective plate 14 can be slidably mounted on the outer side of the box body 10, so that the protective plate 14 can slide along the outer side of the box body 10 to open the second inspection opening 13a, or slide along the outer side of the box body 10 to close the second inspection opening 13a.

[0077] When it is necessary to detect the pressure of the expansion tank 50 or to inflate the expansion tank 50, the protective plate 14 can be slid to open the second inspection port 13a so that the inflation port 50a is exposed from the second inspection port 13a, and the staff can connect the pipeline to the inflation port 50a through the second inspection port 13a.

[0078] When the pressure test of the expansion tank 50 is completed, or the inflation of the expansion tank 50 is completed, the protective plate 14 can be slid to close the second inspection port, so that the protective plate 14 can prevent dust, sewage and other debris from entering the box body 10 from the second inspection port 13a.

[0079] In some other embodiments, the protective plate 14 can be rotatably installed on the outer surface of the box body 10, so that the protective plate 14 can be rotated to open the second inspection port 13a, or rotated to close the second inspection port 13a. The role of the protective plate 14 is the same as described above and will not be repeated here.

[0080] In some embodiments, see Figure 4 The hydraulic module can further include an inflation tube 60, which can be inserted into the second inspection port 13a, and a first end of the inflation tube 60 can extend to communicate with the inflation port 50a, and a second end of the inflation tube 60 can be located outside the box body 10, and the first end and the second end of the inflation tube 60 are opposite ends.

[0081] Optionally, the inflation tube 60 can be a round tube, and the diameter of the inflation tube 60 is smaller than the diameter of the second inspection port 13a, so that the inflation tube 60 can be easily inserted into the second inspection port 13a. The inflation tube 60 can be a hose with adjustable length, for example, the inflation tube 60 is a telescopic tube, a corrugated tube, etc., and the length of the inflation tube 60 can be adjusted according to actual usage.

[0082] To be more clear, when it is necessary to detect the pressure of the expansion tank 50 or to inflate the expansion tank 50, the second end of the inflation tube 60 can be extended to the outside of the box body 10, and the length of the inflation tube 60 can be extended to facilitate the connection of the inflation tube 60 with external equipment. After adjusting the pressure in the expansion tank 50, the length of the inflation tube 60 can be shortened, and the second end of the inflation tube 60 can be retracted into the inside of the box body 10, that is, the inflation tube 60 is retracted into the box body 10, and the cover plate is closed to close the second inspection port 13a, which can facilitate the retraction of the inflation tube 60.

[0083] Therefore, when the air tube 60 needs to be used, the air tube 60 can be directly pulled out from the interior of the box body 10 .

[0084] The same or similar numbers in the drawings of this embodiment correspond to the same or similar items; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship, they are based on the orientation or position relationship described in the drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
