For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0040] In the following description, specific details such as specific device structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known devices, apparatuses, circuits, and methods are omitted to avoid obstructing the description of the present invention with unnecessary details.

[0041] like Figures 1 to 3As shown, the air source heat pump device 1 in the first embodiment of the utility model includes a frame 10, a compressor module 20, an indoor heat exchanger 30, a hydraulic module 40, an outdoor heat exchange module 50 and a domestic hot water module 60. The compressor module 20, the indoor heat exchanger 30, the hydraulic module 40, the outdoor heat exchange module 50 and the domestic hot water module 60 are all arranged in the frame 10, and are interconnected to form a circulation loop.

[0042] The domestic hot water module 60 can be connected to the domestic hot water tank to form a domestic hot water loop, so that the air source heat pump device 1 can form a refrigerant circulation loop acting on the domestic hot water loop to achieve the heating of domestic hot water, and can also be connected to the terminal device to form a refrigerant circulation loop acting on the terminal device to achieve the cooling and heating functions of the terminal device.

[0043] At the same time, the air source heat pump device 1 integrates the hydraulic module 40 into the frame 10 , and no additional hydraulic module is required during use, thereby improving the integration of the air source heat pump device 1 .

[0044] Specifically, the rack 10 defines a first chamber 15 and a second chamber 16 adjacent to each other. The outdoor heat exchange module 50 is disposed in the first chamber 15. The compressor module 20, the indoor heat exchanger 30, the hydraulic module 40 and the domestic hot water module 60 are disposed in the second chamber 16.

[0045] The distribution of the compressor module 20, the indoor heat exchanger 30, the hydraulic module 40, the outdoor heat exchange module 50 and the domestic hot water module 60 in the two chambers of the rack 10 improves the rationality of the internal layout of the air source heat pump device 1, so as to facilitate the miniaturization of the air source heat pump device 1.

[0046] It should be understood that “left and right adjacent” refers to the positional relationship between the first chamber 15 and the second chamber 16 at the angle set when the air source heat pump device 1 is working, which can be roughly referred to Figure 2 as well as Figure 3 Angle shown.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the frame 10 includes a shell 11 and a middle partition 12. The shell 11 defines a receiving cavity. The middle partition 12 is vertically arranged in the receiving cavity to separate the receiving cavity into a first chamber 15 and a second chamber 16.

[0048] In this embodiment, the housing 11 is in a cubic shape, and the accommodating cavity defined by it is also in a cubic shape. It is formed by a cover plate, a bottom plate, and a plurality of side plates that are detachably connected to facilitate disassembly, assembly, maintenance, etc.

[0049] Specifically, the horizontal cross section of the shell 11 is a rectangle, and the middle partition 12 is a longitudinally long rectangle. In a top view, the short axis of the rectangle of the shell 11 at this angle is parallel to the extension direction of the middle partition 12 at this angle.

[0050] In some optional embodiments, the housing 11 may also be in other structures such as a polygonal column, a cylinder, an irregular shape, etc. The housing 11 may also have at least a portion of a plate-like structure fixed to each other by welding, integral molding, etc.

[0051] It should be understood that the descriptions of angles such as "vertical" and "horizontal" are all based on the angles set when the air source heat pump device 1 is working, which can be roughly referred to as Figure 2 as well as Figure 3 Angle shown.

[0052] The indoor heat exchanger 30 is used to communicate with the terminal device to form a terminal water loop for heat exchange with the refrigerant. The indoor heat exchanger 30 can exchange heat between the refrigerant in the refrigerant circulation loop and the water in the terminal water loop to prepare cold water or hot water required by the terminal device. It is installed on the middle partition 12 to ensure its stability in the second chamber 16 during operation, facilitate the layout of the pipeline, and improve the space utilization of the second chamber 16.

[0053] In some embodiments, the hydraulic module 40 includes an expansion tank 41 and an indoor water pump 42. The indoor water pump 42 is connected to the indoor heat exchanger 30, and is disposed between the indoor heat exchanger 30 and the terminal device, and is used to pump water in the terminal water circuit. The expansion tank 41 is connected to the terminal water circuit, and is used to buffer the pressure fluctuation in the terminal water circuit, ensure the stability of the water circuit pressure, and avoid rapid changes in pressure. Figure 2 As shown, the expansion tank 41 is disposed on the middle partition plate 12 .

[0054] Read also Figure 3 In this embodiment, the expansion tank 41 and the indoor heat exchanger 30 are arranged on the middle partition 12 in a substantially parallel position, and are both located in the middle and upper part of the middle partition 12. The height of the indoor water pump 42 in the second chamber 16 corresponds to the indoor heat exchanger 30 to shorten the length of the connecting pipe between the two. At the same time, the indoor water pump 42 is fixed to the side wall of the shell 11 defining the second chamber 16 by a bracket or other structure to ensure the stability of the indoor water pump 42 during operation and alleviate the impact of its own vibration on the pipeline.

[0055] Furthermore, in order to improve the stability of the expansion tank 41 when installed on the middle partition 12, it is fixed to the middle partition 12 by a fixing frame and a fixing plate. The fixing frame is roughly in the shape of a "F" and is arranged around the circumference of the expansion tank 41, and its two ends are respectively connected to the middle partition 12. The fixing plate is horizontally connected to the middle partition 12 and is located at the lower end of the expansion tank 41. The expansion tank 41 is placed on the fixing plate.

[0056] In some embodiments, the air source heat pump device 1 further includes an enthalpy increasing module 80 for improving heat exchange efficiency. The enthalpy increasing module 80 is disposed in the second chamber 16 and includes a heat exchanger 81. The heat exchanger 81 is mounted on the middle partition plate 12.

[0057] In this embodiment, the heat exchanger 81 and the expansion tank 41 are both located on the same side of the indoor heat exchanger 30, and the heat exchanger 81 is located below the expansion tank 41. This makes the occupied area of ​​the smaller heat exchanger 81 and the expansion tank 41 on the middle partition 12 roughly match the larger indoor heat exchanger 30, further improving the space utilization and realizing the miniaturization of the equipment.

[0058] For example Figure 2 As shown, in some embodiments, the domestic hot water module 60 is located below the compressor module 20 , and the indoor heat exchanger 30 and the hydraulic module 40 are both located above the compressor module 20 .

[0059] Since the compressor module 20 needs to be connected to the domestic hot water module 60, the indoor heat exchanger 30 and the hydraulic module 40 respectively, it is arranged between the domestic hot water module 60 and the indoor heat exchanger 30 and the hydraulic module 40, which can facilitate the connection of pipelines and valves and reduce the length of pipelines, making the spatial layout of the air source heat pump device 1 more reasonable and realizing the miniaturization of the product.

[0060] It should be understood that “the domestic hot water module 60 is located below the compressor module 20” means that the space occupied by the domestic hot water module 60 as a whole is approximately below the space occupied by the compressor module 20 as a whole. It does not mean that all components of the domestic hot water module 60 must be below all components of the compressor module 20. In other words, some components of the domestic hot water module 60 may be at approximately the same level as the compressor module 20, and some components may be located below the compressor module 20; it is also possible that all components of the domestic hot water module 60 are located below the compressor module 20. The same applies to “the indoor heat exchanger 30 and the hydraulic module 40 are both located above the compressor module 20”.

[0061] Specifically, the rack 10 further includes a support plate 13, which is perpendicular to the middle partition plate 12 and horizontally arranged in the second chamber 16, so as to separate the second chamber 16 into an upper chamber 161 and a lower chamber 162 adjacent to each other. The compressor module 20 is mounted on the support plate 13 and is located in the upper chamber 161. The indoor heat exchanger 30 and the hydraulic module 40 are both located in the upper chamber 161.

[0062] In this embodiment, the frame 10 includes a plurality of legs 14, which are located in the lower chamber 162. The legs 14 are vertically arranged on the bottom wall of the shell 11, with the bottom ends connected to the bottom wall of the shell 11 and the top ends connected to the support plate 13. The legs 14 are used to support the support plate 13 so that the support plate 13 is horizontally arranged in the second chamber 16 to support the compressor module 20.

[0063] Read also Figure 3 In some embodiments, the compressor module 20 includes a compressor 21 and a gas-liquid separator 22, both of which are mounted on a support plate 13 and fixed by structures such as brackets to improve installation stability and alleviate the impact of vibration on the equipment during operation.

[0064] In some embodiments, the air source heat pump device 1 further includes a liquid storage tank 70, which is also located in the upper chamber 161, mounted on the support plate 13, and fixed by a structure such as a bracket.

[0065] Specifically, the installation positions of the liquid storage tank 70, the compressor 21 and the gas-liquid separator 22 on the support plate 13 are roughly distributed in a triangle to ensure uniform weight distribution of the three on the support plate 13 and avoid uneven force on the support plate 13 and the legs 14, thereby improving the stability of the equipment.

[0066] It should be understood that, in the present embodiment, the indoor heat exchanger 30 , the hydraulic module 40 and the heat exchanger 81 are all located above the liquid storage tank 70 and the compressor module 20 .

[0067] In some other optional embodiments, some parts of the indoor heat exchanger 30 , the hydraulic module 40 and the heat exchanger 81 may be approximately at the same level as the liquid storage tank 70 and the compressor module 20 .

[0068] The indoor heat exchanger 30, the hydraulic module 40 and the heat exchanger 81 are all arranged above the liquid storage tank 70 and the compressor module 20, and the indoor heat exchanger 30, the expansion tank 41 and the heat exchanger 81 and other large components are all arranged on the middle partition 12. In addition to ensuring the stability of the large components in the rack 10, a certain space can be made above the liquid storage tank 70 and the compressor module 20 for centrally arranging the pipes and valves connecting the various components, so as to further improve the space utilization and realize the miniaturization of the equipment.

[0069] In some embodiments, the domestic hot water module 60 includes a domestic hot water heat exchanger 61 and a domestic hot water pump 62. The domestic hot water heat exchanger 61 and the domestic hot water pump 62 are both arranged in the lower chamber 162. By arranging a pipe on the support plate 13, the domestic hot water module 60 is connected to other modules in the upper chamber 161. One end of the domestic hot water pump 62 is connected to the domestic hot water heat exchanger 61, and the other end is used to be connected to the domestic hot water tank. When the domestic hot water tank is connected to the air source heat pump device 1, the domestic hot water heat exchanger 61, the domestic hot water pump 62 and the domestic hot water tank can form a domestic hot water loop to heat domestic water.

[0070] Specifically, the domestic hot water heat exchanger 61 and the domestic hot water pump 62 are respectively fixed to the bottom wall of the lower chamber 162, that is, the bottom wall of the housing 11, through structures such as brackets, so as to reduce the influence of vibration on the equipment during operation.

[0071] For example Figure 2 As shown, in some embodiments, the outdoor heat exchange module 50 includes an outdoor heat exchanger 51 and a fan 52. The outdoor heat exchanger 51 is used to exchange heat between the refrigerant in the refrigerant circulation loop and the outside air to achieve heat absorption or heat dissipation of the refrigerant. The fan 52 is used to drive the outside air to exchange heat with the outdoor heat exchanger 51.

[0072] Specifically, the outdoor heat exchanger 51 and the fan 52 are both disposed in the first chamber 15 and fixed to the bottom wall of the first chamber 15, that is, the bottom wall of the housing 11, through structures such as brackets to reduce the impact of vibration on the equipment during operation.

[0073] Specifically, the horizontal cross section of the outdoor heat exchanger 51 is L-shaped. The plane where the long side of the L-shape is located is perpendicular to and adjacent to the middle partition plate 12. The plane where the short side of the L-shape is located is parallel to and spaced from the middle partition plate 12.

[0074] In this embodiment, the outdoor heat exchanger 51 can serve as part of the side wall of the housing 11. That is, the outdoor heat exchanger 51 is arranged at the periphery of the first chamber 15, increasing its own size while making room for the fan 52. The outdoor heat exchanger 51 is arranged around the fan 52, which can further improve the space utilization of the equipment and improve the heat dissipation effect of the fan 52.

[0075] In some embodiments, the air source heat pump device 1 further includes an electric control module 100 , which is disposed at the top end of the housing 11 and is electrically connected to the components in each module to control the operation of the entire air source heat pump device 1 .

[0076] Specifically, the electric control module 100 includes a frame 101, a main control board 102, a drive board 103, a heat sink 104 and other components. The frame 101 is fixed in the housing 11, located at the top of the middle partition 12, and is used to carry the main control board 102, the drive board 103 and the heat sink 104. The heat sink 104 is used to dissipate heat for the drive board 103.

[0077] The main control board 102 is located in the second chamber 16. The driving board 103 and the heat sink 104 are both located in the first chamber 15. In addition to the heat sink 104, the heat generated by the driving board 103 can also be dissipated by the fan 52 to improve the heat dissipation effect.

[0078] In this embodiment, the frame 101 includes a main body and a connecting plate. The main body is made of a plurality of plates integrally formed, and the driving plate 103 and the heat sink 104 are both arranged on the main body. The connecting plate is installed on the main body by connecting members such as bolts, and is used to set the main control board 102.

[0079] Continue reading Figure 2 In this embodiment, the main body is horizontally arranged at the top of the middle partition 12, partly located in the first chamber 15, and partly located in the second chamber 16. It is respectively connected to the top of the bracket of the fan 52, the top of the shell 11 and the middle partition 12 through bolts and other connecting parts.

[0080] In some other optional embodiments, the main body of the frame 101 may also be composed of a plurality of plates connected into one by welding, bolting, etc.

[0081] Furthermore, the main control board 102 is arranged parallel to and adjacent to the side wall of the housing 11 , so that the main control board 102 is vertically arranged at the top of the second chamber 16 , and the connection port on the main control board 102 is arranged downward.

[0082] When the electric control module 100 is connected to components in other modules, the downwardly disposed ports face other modules located below the electric control module 100, thereby facilitating electrical connection between the main control board 102 and components in other modules.

[0083] At the same time, the main control board 102 arranged parallel to the side wall of the housing 11 can facilitate the operation of the operator. During the assembly process, the operator can connect the main control board 102 with other components by standing in front of the housing 11. This avoids the problem of other components and pipelines blocking the operation during the connection process. At the same time, it is also convenient to repair the main control board 102.

[0084] In this embodiment, the main control board 102 is disposed adjacent to the front side plate of the housing 11 .

[0085] It should be understood that the “front side panel”, in this embodiment, refers to the side panel toward which the fan 52 is facing.

[0086] Further, the driving plate 103 is disposed on the side of the main body facing away from the fan 52, and the heat sink 104 corresponds to the driving plate 103 and is disposed on the side of the main body facing the fan 52. That is, the heat sink 104 is disposed facing the fan 52.

[0087] By arranging the heat sink 104 to face the fan 52 , the fan 52 can be used to improve the heat dissipation capacity of the heat sink 104 , thereby improving the heat dissipation effect on the driving board 103 .

[0088] Furthermore, at least part of the heat sink 104 can be set to different lengths. For example, the length of the heat sink 104 can be flexibly adjusted according to the free space of the first chamber 15 where the heat sink 104 is located, so that the heat sink 104 can make full use of the space of the first chamber 15, increase its own size and area, and thus improve the heat dissipation effect.

[0089] like Figure 4 As shown, since the heat sink 104 is disposed at the top end facing the fan 52, the lengths of some heat sinks 104 are different, so that the curvature defined by the end of the heat sink 104 can be adapted to the curvature of the edge of the fan 52 blade at the corresponding position. In this embodiment, the curvature defined by the heat sink 104 is roughly parallel to the curvature of the fan 52 blade.

[0090] It should be understood that the "end of the heat sink 104" refers to the end of the heat sink 104 away from the main body. Figure 4 The angle shown is the lowermost end of the heat sink 104 .

[0091] In some other optional embodiments, the electric control module 100 may also be located at other positions such as the lower end of the housing 11 .

[0092] When the electric control module 100 or the driving board 103 is arranged at other positions, so that the size of the environment space where the heat sink 104 is located changes, the length of the heat sink 104 and the shape defined by the end can be flexibly adjusted accordingly. The length only needs to achieve high utilization of the space.

[0093] In some embodiments, the air source heat pump device 1 further includes a reversing valve module 90, which includes at least one reversing valve, which is disposed in the upper chamber 161 and connected between the pipes. This allows a certain pipe section to have different conduction possibilities in different modes, thereby reducing the number and length of pipes and further improving the miniaturization of the device.

[0094] Specifically, in this embodiment, there are three reversing valves, which are respectively defined as a first reversing valve 91, a second reversing valve 92 and a third reversing valve 93. The first reversing valve 91 is a four-way valve, and the second reversing valve 92 and the third reversing valve 93 are both three-way valves.

[0095] In some embodiments, the enthalpy increasing module 80 further includes an auxiliary throttling device 82 and a main throttling device 83 ( Figures 1 to 3 not shown).

[0096] In this embodiment, the reversing valve module 90 , the auxiliary throttling device 82 and the main throttling device 83 are all disposed in the upper chamber 161 .

[0097] The present application will be further described below through the operation of the air source heat pump device 1 in various modes:

[0098] The terminal device connected to the air source heat pump device 1 is now defined as the terminal device 2, and the domestic hot water tank is defined as the water tank 3.

[0099] like Figure 5 As shown, the indoor heat exchanger 30 includes a first refrigerant port 31, a second refrigerant port 32, a first hot water port 33 and a first cold water port 34. The outdoor heat exchanger 51 includes a third refrigerant port 511 and a fourth refrigerant port 512. The domestic hot water heat exchanger 61 includes a fifth refrigerant port 611, a sixth refrigerant port 612, a second hot water port 613 and a second cold water port 614.

[0100] The first reversing valve 91 includes a first valve port 911, a second valve port 912, a third valve port 913 and a fourth valve port 914. The second reversing valve 92 includes a fifth valve port 921, a sixth valve port 922 and a seventh valve port 923. The third reversing valve 93 includes an eighth valve port 931, a ninth valve port 932 and a tenth valve port 933.

[0101] The heat exchanger 81 includes a refrigerant main inlet 811 , a refrigerant auxiliary inlet 812 , a refrigerant main outlet 813 , and a refrigerant auxiliary outlet 814 .

[0102] The first end of the enthalpy increase module 80 is divided into two paths. One path passes through the refrigerant main inlet 811, the refrigerant main outlet 813 and the main throttling device 83 (i.e., passes through the refrigerant main path) in sequence, and is connected to the fourth refrigerant port 512 of the outdoor heat exchanger 51 or the first refrigerant port 31 of the indoor heat exchanger 30. The other path passes through the auxiliary throttling device 82, the refrigerant auxiliary inlet 812 and the refrigerant auxiliary outlet 814 (i.e., passes through the refrigerant auxiliary path) in sequence, and is connected to the enthalpy increase port 211 of the compressor 21.

[0103] The auxiliary throttling device 82 can reduce the refrigerant temperature in the enthalpy-increasing auxiliary circuit, so that the refrigerant in the heat exchanger 81 can absorb the refrigerant heat from the refrigerant main circuit more efficiently. To further reduce the refrigerant temperature in the refrigerant main circuit.
