[0045] In the following description, specific details such as specific device structures, techniques, etc. are presented in order to thoroughly understand the embodiments of the present application. However, it should be clear to those skilled in the art that the present application 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 unnecessary details that hinder the description of the present application.

[0046] As shown in FIGS. 1-6, the air source heat pump device 1 in the first embodiment of the present application includes a rack 10, a compressor module 20, an indoor heat exchanger 30, a hydraulic module 40, an outdoor heat exchanger module 50, and a domestic hot water module 60. Among them, the compressor module 20, the indoor heat exchanger 30, the hydraulic module 40, the outdoor heat exchanger module 50, and the domestic hot water module 60 are all arranged in the rack 10 and are connected with each other to form a circulating loop.

[0047] Among them, the domestic hot water module 60 can be connected with a domestic hot water tank to form a domestic hot water loop. So that the air source heat pump device 1 can form a refrigerant circulating loop acting on the domestic hot water loop to heat the domestic hot water, and can also be connected with an end device to form a refrigerant circulating loop acting on the end device to realize the refrigeration and heating functions of the end device.

[0048] At the same time, the air source heat pump device 1 integrates the hydraulic module 40 into the rack 10, so that the hydraulic module does not need to be additionally arranged during use, and the integration degree of the air source heat pump device 1 is improved.

[0049] Specifically, the rack 10 defines a first chamber 15 and a second chamber 16 adjacent to each other. Among them, the outdoor heat exchanger module 50 is arranged 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 arranged in the second chamber 16.

[0050] The distribution of the compressor module 20, the indoor heat exchanger 30, the hydraulic module 40, the outdoor heat exchanger 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 realize the miniaturization of the air source heat pump device 1.

[0051] It should be understood that "adjacent to each other" 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. The angle can be referred to FIGS. 2 and 3.

[0052] As shown in FIGS. 1 and 2, in some embodiments, the rack 10 includes a shell 11 defining a receiving cavity and a partition plate 12. The partition plate 12 is vertically arranged in the receiving cavity to divide the receiving cavity into the first chamber 15 and the second chamber 16.

[0053] In the present embodiment, the shell 11 is in the shape of a square, and the receiving cavity defined thereby is also in the shape of a square. It is formed by a cover plate, a bottom plate, and a plurality of side plates which are detachably connected to facilitate disassembly, maintenance, etc.

[0054] Specifically, the horizontal cross section of the shell 11 is rectangular. The partition plate 12 is longitudinally rectangular. In the plan view, the short axis of the rectangle of the shell 11 is parallel to the extending direction of the partition plate 12 in the plan view.

[0055] In some optional embodiments, the shell 11 can also be a polygonal column, a cylindrical column, an irregular shape, or other structures. The shell 11 can also be fixed by welding, one-piece forming, or other methods.

[0056] It should be understood that the description of the angles such as "vertically standing", "horizontally" is based on the angle set when the air source heat pump device 1 is working, which can be referred to the angles shown in FIG. 2 and FIG. 3.

[0057] The indoor heat exchanger 30 is used to communicate with the terminal device to form a terminal water circuit 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 circuit to prepare cold water or hot water required by the terminal device. The indoor heat exchanger 30 is installed on the partition plate 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.

[0058] In some embodiments, the hydraulic module 40 includes an expansion tank 41 and an indoor water pump 42. The indoor water pump 42 communicates with the indoor heat exchanger 30 and is arranged between the indoor heat exchanger 30 and the terminal device to pump the water in the terminal water circuit. The expansion tank 41 communicates with the terminal water circuit to buffer the pressure fluctuation in the terminal water circuit, ensure the stability of the water circuit pressure, and avoid rapid changes in pressure. As shown in FIG. 2, the expansion tank 41 is arranged on the partition plate 12.

[0059] Referring to FIG. 3 and FIG. 5, in the present embodiment, the expansion tank 41 is located on one side of the indoor heat exchanger 30 in the horizontal direction, and is substantially parallel to the arrangement position of the indoor heat exchanger 30 on the partition plate 12, both of which are located at the upper middle part of the partition plate 12. The height of the indoor water pump 42 in the second chamber 16 corresponds to the indoor heat exchanger 30, and is located on the side of the indoor heat exchanger 30 away from the partition plate 12, and the line connecting the indoor water pump 42 and the indoor heat exchanger 30 is substantially perpendicular to the partition plate 12, so as to shorten the length of the connecting pipeline between the indoor water pump 42 and the indoor heat exchanger 30. At the same time, the indoor water pump 42 is fixed on the side wall of the shell 11 defining the second chamber 16 by a support or other structure to ensure the stability of the indoor water pump 42 during operation and to alleviate the influence of its own vibration on the pipeline.

[0060] In some embodiments, to improve the stability of the expansion tank 41 installed on the partition plate 12, it is fixed to the partition plate 12 by a fixing bracket and a fixing plate. The fixing bracket is generally Z-shaped and surrounds the circumference of the expansion tank 41, with its two ends connected to the partition plate 12 respectively. The fixing plate is horizontally connected to the partition plate 12 and located at the lower end of the expansion tank 41. The expansion tank 41 is placed on the fixing plate.

[0061] In some embodiments, the air source heat pump device 1 further includes an enthalpy enhancement module 80 for improving heat exchange efficiency. The enthalpy enhancement module 80 is disposed within the second chamber 16 and includes a heat exchanger 81. The heat exchanger 81 is mounted on the partition plate 12.

[0062] Specifically, as shown in Figure 5, the heat exchanger 81 and the expansion tank 41 are both located on the same horizontal side of the indoor heat exchanger 30, and the expansion tank 41 is roughly corresponding to the indoor heat exchanger 30 in the vertical direction, with the heat exchanger 81 located below the expansion tank 41 in the vertical direction. This arrangement ensures that the smaller heat exchanger 81 and the expansion tank 41 occupy roughly the same area on the partition plate 12 as the larger indoor heat exchanger 30, and also facilitates pipe connections, thereby improving space utilization and achieving equipment miniaturization.

[0063] As shown in Figure 2, in some embodiments, the domestic hot water module 60 is located below the compressor module 20, while the indoor heat exchanger 30 and the hydraulic module 40 are both located above the compressor module 20.

[0064] 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, it is positioned between the domestic hot water module 60 and the indoor heat exchanger 30 and hydraulic module 40. This facilitates the connection of pipes and valves and reduces the length of the pipes. This makes the spatial layout of the air source heat pump equipment 1 more rational and enables product miniaturization.

[0065] It's important to understand 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 roughly below the space occupied by the compressor module 20. It does not mean that all components of the domestic hot water module 60 are necessarily below all components of the compressor module 20. That is, some components of the domestic hot water module 60 may be at roughly the same horizontal level as the compressor module 20, while others may be located below it; alternatively, all components of the domestic hot water module 60 may be located below the compressor module 20. The same logic applies to "the indoor heat exchanger 30 and the hydraulic module 40 are both located above the compressor module 20."

[0066] Specifically, the rack 10 further comprises a support plate 13, which is perpendicular to the partition plate 12 and horizontally arranged in the second chamber 16. The second chamber 16 is thus divided into an upper chamber 161 and a lower chamber 162 arranged in sequence. The compressor module 20 is installed on the support plate 13 and located in the upper chamber 161. The indoor side heat exchanger 30 and the hydraulic module 40 are both located in the upper chamber 161.

[0067] In the embodiment, the rack 10 comprises a plurality of legs 14 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 and the compressor module 20 is supported.

[0068] Referring to FIG. 3, in some embodiments, the compressor module 20 comprises a compressor 21 and a gas-liquid separator 22, both of which are installed on the support plate 13 and fixed by a bracket or the like to improve the stability of installation and alleviate the influence of vibration on the equipment during operation.

[0069] In some embodiments, the air source heat pump equipment 1 further comprises a liquid storage tank 70, which is also located in the upper chamber 161 and installed on the support plate 13 and fixed by a bracket or the like.

[0070] 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 triangularly distributed to ensure the uniformity of weight distribution of the three on the support plate 13 and avoid uneven stress on the support plate 13 and the legs 14. In turn, the stability of the equipment is improved.

[0071] It should be understood that, in the embodiment, the indoor side 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.

[0072] In other optional embodiments, some components of the indoor side heat exchanger 30, the hydraulic module 40 and the heat exchanger 81 can also be roughly at the same horizontal level as the liquid storage tank 70 and the compressor module 20.

[0073] By arranging the indoor side heat exchanger 30, the hydraulic module 40 and the heat exchanger 81 above the liquid storage tank 70 and the compressor module 20 and arranging larger components such as the indoor side heat exchanger 30, the expansion tank 41 and the heat exchanger 81 on the partition plate 12, the stability of larger components in the rack 10 can be ensured, and a certain space above the liquid storage tank 70 and the compressor module 20 can be left for centralized arrangement of pipelines and valves connected between components, so as to improve the space utilization and realize the miniaturization of the equipment.

[0074] In some embodiments, the domestic hot water module 60 comprises a domestic hot water heat exchanger 61 and a domestic hot water pump 62. Both the domestic hot water heat exchanger 61 and the domestic hot water pump 62 are arranged in the lower chamber 162. The domestic hot water module 60 is connected to other modules in the upper chamber 161 by pipes passing through the support plate 13. 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 connect to a 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 circuit to heat domestic water.

[0075] 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, i.e., the bottom wall of the shell 11, by a bracket or other structure. This reduces the impact of vibration during operation on the device.

[0076] As shown in FIG. 2, in some embodiments, the outdoor heat exchange module 50 comprises an outdoor side heat exchanger 51 and a fan 52. The outdoor side 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 side heat exchanger 51.

[0077] Specifically, the outdoor side heat exchanger 51 and the fan 52 are both arranged in the first chamber 15 and are respectively fixed to the bottom wall of the first chamber 15, i.e., the bottom wall of the shell 11, by a bracket or other structure. This reduces the impact of vibration during operation on the device.

[0078] Specifically, the horizontal cross section of the outdoor side heat exchanger 51 is L-shaped. The plane in which the long side of the L-shaped cross section is located is perpendicular to the partition plate 12 and is arranged adjacent to the partition plate 12. The plane in which the short side of the L-shaped cross section is located is parallel to the partition plate 12 and is arranged spaced apart from the partition plate 12.

[0079] In this embodiment, the outdoor side heat exchanger 51 can act as part of the side wall of the shell 11. That is, the outdoor side heat exchanger 51 is arranged at the periphery of the first chamber 15 to increase its own size while providing space for the fan 52. The outdoor side heat exchanger 51 is arranged around the periphery of the fan 52, which can improve the space utilization of the device and improve the heat dissipation effect of the fan 52.

[0080] In some embodiments, the air source heat pump device 1 further comprises an electric control module 100 arranged at the top end of the shell 11 and electrically connected to each component in each module to control the operation of the entire air source heat pump device 1.

[0081] Specifically, the electric control module 100 comprises a frame 101, a main control board 102, a driving board 103, and a heat sink 104, etc. The frame 101 is fixed in the shell 11 and located at the top end of the partition plate 12, for carrying the main control board 102, the driving board 103, and the heat sink 104. The heat sink 104 is used for heat dissipation of the driving board 103.

[0082] 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. The heat generated by the driving board 103 can be dissipated by the heat sink 104 and the fan 52.

[0083] In the embodiment, the frame 101 comprises a main body and a connecting plate. The main body is integrally formed by a plurality of plate pieces, and the driving board 103 and the heat sink 104 are arranged on the main body. The connecting plate is installed on the main body by bolts or other connecting members, for arranging the main control board 102.

[0084] Referring to FIG. 2, in the embodiment, the main body is horizontally arranged at the top end of the partition plate 12, partially located in the first chamber 15 and partially located in the second chamber 16. It is connected to the top end of the bracket of the fan 52, the top end of the shell 11, and the partition plate 12 by bolts or other connecting members.

[0085] In other optional embodiments, the main body of the frame 101 can also be integrally connected by a plurality of plate pieces through welding, bolt connection, etc.

[0086] In one embodiment, the main control board 102 is arranged parallel and adjacent to the side wall of the shell 11. The main control board 102 is vertically arranged at the top end of the second chamber 16, and the connecting port on the main control board 102 is arranged downward.

[0087] When the electric control module 100 and other modules are connected, the downwardly arranged port faces the other modules located below the electric control module 100, thereby facilitating the electrical connection between the main control board 102 and the components of other modules.

[0088] At the same time, the main control board 102 arranged parallel and adjacent to the side wall of the shell 11 can facilitate the operation of the operator. During assembly, the operator can stand in front of the shell 11 to connect the main control board 102 and other components. This avoids the shielding problem of other components and pipelines during connection. At the same time, it is also convenient for the maintenance of the main control board 102.

[0089] In the embodiment, the main control board 102 is arranged adjacent to the front side plate of the shell 11.

[0090] It should be understood that the "front side plate" in this embodiment refers to the side plate facing the fan 52.

[0091] In one embodiment, the drive plate 103 is arranged on the side of the main body away from the fan 52, and the heat dissipation fin 104 corresponding to the drive plate 103 is arranged on the side of the main body facing the fan 52. That is, the heat dissipation fin 104 is arranged to face the fan 52.

[0092] By arranging the heat dissipation fin 104 to face the fan 52, the heat dissipation capacity of the heat dissipation fin 104 can be improved by means of the fan 52, thereby improving the heat dissipation effect on the drive plate 103.

[0093] In one embodiment, at least part of the heat dissipation fin 104 can also be arranged to have different lengths. For example, the length of the heat dissipation fin 104 can be flexibly adjusted according to the free space at the position of the first chamber 15 where the heat dissipation fin 104 is located, so that the heat dissipation fin 104 can utilize the space of the first chamber 15 as much as possible, thereby increasing its own size area and improving the heat dissipation effect.

[0094] As shown in FIG. 4, since the heat dissipation fin 104 is arranged to face the fan 52 at the top end, and the lengths of part of the heat dissipation fin 104 are different, the end of this part of the heat dissipation fin 104 can be adapted to the edge curvature of the fan 52 blade at the corresponding position. In this embodiment, the curvature defined by the heat dissipation fin 104 is substantially parallel to the blade curvature of the fan 52.

[0095] It should be understood that the "end of the heat dissipation fin 104" refers to the end of the heat dissipation fin 104 away from the main body, which is the lowermost end of the heat dissipation fin 104 in the angle shown in FIG. 4.

[0096] In other optional embodiments, the electronic control module 100 can also be located at other positions such as the lower end of the shell 11.

[0097] When the electronic control module 100 or the drive plate 103 is arranged at other positions, so that the size of the environmental space where the heat dissipation fin 104 is located changes, the length of the heat dissipation fin 104 and the shape defined by the end thereof can be flexibly adjusted. The length only needs to achieve high utilization of space.

[0098] In some embodiments, the air source heat pump device 1 further comprises a reversing valve module 90 comprising at least one reversing valve arranged in the upper chamber 161 and connected between the pipes. This can make a certain pipe section have different conduction possibilities in different modes, thereby reducing the number and length of the pipes and improving the miniaturization of the device.

[0099] Specifically, in the present embodiment, the number of reversing valves is three, which are defined as a first reversing valve 91, a second reversing valve 92 and a third reversing valve 93 respectively. Among them, 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.

[0100] In some embodiments, the enthalpy increasing module 80 further comprises an auxiliary throttling device 82 and a main throttling device 83 (not shown in Figures 1 to 3) which are both in communication with the heat exchanger 81.

[0101] In the present embodiment, the reversing valve module 90, the auxiliary throttling device 82 and the main throttling device 83 are all arranged in the upper chamber 161.

[0102] The present application will be described below through the operation of the air source heat pump device 1 in various modes:

[0103] The end device connected to the air source heat pump device 1 will be defined as an end device 2, and the domestic hot water tank will be defined as a water tank 3.

[0104] As shown in Figure 6, the indoor heat exchanger 30 comprises 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 comprises a third refrigerant port 511 and a fourth refrigerant port 512. The domestic hot water heat exchanger 61 comprises a fifth refrigerant port 611, a sixth refrigerant port 612, a second hot water port 613 and a second cold water port 614.

[0105] The first reversing valve 91 comprises 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 comprises a fifth valve port 921, a sixth valve port 922 and a seventh valve port 923. The third reversing valve 93 comprises an eighth valve port 931, a ninth valve port 932 and a tenth valve port 933.

[0106] The heat exchanger 81 comprises a main refrigerant inlet 811, an auxiliary refrigerant inlet 812, a main refrigerant outlet 813 and an auxiliary refrigerant outlet 814.

[0107] Among them, the first end of the enthalpy increasing module 80 is divided into two paths. One of the paths is in communication with the fourth refrigerant port 512 of the outdoor heat exchanger 51 or the first refrigerant port 31 of the indoor heat exchanger 30 after passing through the main refrigerant inlet 811, the main refrigerant outlet 813 and the main throttling device 83 in sequence (i.e. through the main refrigerant path). The other path is in communication with the enthalpy increasing port 211 of the compressor 21 after passing through the auxiliary throttling device 82, the auxiliary refrigerant inlet 812 and the auxiliary refrigerant outlet 814 in sequence (i.e. through the auxiliary refrigerant path).

[0108] The auxiliary throttling device 82 can reduce the temperature of the refrigerant in the enthalpy-increasing auxiliary circuit, so that the refrigerant in the heat exchanger 81 more efficiently absorbs heat from the refrigerant in the main circuit. To reduce the temperature of the refrigerant in the main circuit. This can improve the refrigeration effect of the terminal device 2 in cooling mode, and can improve the heating capacity of the refrigerant under low temperature condition in heating mode. After the refrigerant in the main circuit is cooled by heat exchange, it is reduced in temperature by the main throttling device 83, and then enters the outdoor heat exchanger 51 or the indoor heat exchanger 30. Thus, the heat absorption performance of the refrigerant is improved, that is, the cooling effect of the air source heat pump device 1 is improved.

[0109] The first hot water port 33 and the first cold water port 34 of the indoor heat exchanger 30 are respectively connected to the terminal device 2 to form a terminal circuit, and the expansion tank 41 and the indoor water pump 42 are respectively arranged on the terminal circuit (not shown in FIG. 6).

[0110] The second hot water port 613 and the second cold water port 614 of the domestic hot water heat exchanger 61 are respectively connected to the water tank 3 to form a domestic hot water circuit. The domestic hot water pump 62 is arranged on the domestic hot water circuit (not shown in FIG. 6).

[0111] The output end of the compressor 21 is connected to the fifth valve port 921. The seventh valve port 923, the eighth valve port 931 and the first valve port 911 are connected to each other. The second valve port 912 is connected to the third refrigerant port 511 of the outdoor heat exchanger 51. The third valve port 913 is connected to the input end of the gas-liquid separator 22. The output end of the gas-liquid separator 22 is connected to the input end of the compressor 21.

[0112] The input end of the liquid storage tank 70 is connected to the first refrigerant port 31 of the indoor heat exchanger 30 and the tenth valve port 933 of the third reversing valve 93. A one-way valve is arranged between the input end of the liquid storage tank 70 and the first refrigerant port 31, and a one-way valve is also arranged between the input end of the liquid storage tank 70 and the tenth valve port 933. The output end of the liquid storage tank 70 is connected to the fourth refrigerant port 512 of the outdoor heat exchanger 51 through the enthalpy-increasing module 80. A one-way valve is also arranged between the output end of the liquid storage tank 70 and the inlet end of the enthalpy-increasing module 80.

[0113] The sixth valve port 922 of the second reversing valve 92 is connected to the fifth refrigerant port 611 of the domestic hot water heat exchanger 61. The ninth valve port 932 of the third reversing valve 93 is connected to the sixth refrigerant port 612 of the domestic hot water heat exchanger 61.

[0114] The air source heat pump device 1 can realize multiple operating modes such as refrigeration and all-heat recovery for domestic hot water, refrigeration and waste heat recovery for domestic hot water, heating and domestic hot water, pure domestic hot water, pure refrigeration, pure heating, etc. through the integration of the indoor heat exchanger 30, the outdoor heat exchanger 51 and the domestic hot water heat exchanger 61.

[0115] As shown in FIG. 7, when in the refrigeration and total heat recovery domestic hot water mode, the third valve port 913 is in communication with the fourth valve port 914. The fifth valve port 921 is in communication with the sixth valve port 922. The ninth valve port 932 is in communication with the tenth valve port 933. The other valve ports of the first reversing valve 91, the second reversing valve 92 and the third reversing valve 93 are closed. At this time, the compressor 21 outputs high-temperature refrigerant, which successively passes through the second reversing valve 92, the fifth refrigerant port 611 and reaches the domestic hot water heat exchanger 61. The high-temperature refrigerant exchanges heat with the domestic water in the domestic hot water circuit in the domestic hot water heat exchanger 61, the domestic water is heated, and the high-temperature refrigerant releases all the heat and becomes low-temperature refrigerant, which successively passes through the sixth refrigerant port 612, the third reversing valve 93, the liquid accumulator 70, the enthalpy increasing module 80 and the first refrigerant port 31 and reaches the indoor heat exchanger 30. The low-temperature refrigerant exchanges heat with the hot water in the terminal water circuit in the indoor heat exchanger 30, absorbs heat to become high-temperature refrigerant, and the hot water is cooled to make the terminal device 2 realize refrigeration function. The high-temperature refrigerant after absorbing heat successively passes through the second refrigerant port 32, the fourth valve port 914, the third valve port 913, the gas-liquid separator 22 and returns to the compressor 21, realizing refrigerant circulation.

[0116] As shown in FIG. 8, when in the refrigeration and waste heat recovery domestic hot water mode, the first valve port 911 is in communication with the second valve port 912. The third valve port 913 is in communication with the fourth valve port 914. The fifth valve port 921 is in communication with the sixth valve port 922. The eighth valve port 931 is in communication with the ninth valve port 932. The other valve ports of the first reversing valve 91, the second reversing valve 92 and the third reversing valve 93 are closed. At this time, the compressor outputs high-temperature refrigerant, which successively passes through the second reversing valve 92, the fifth refrigerant port 611 and reaches the domestic hot water heat exchanger 61. The high-temperature refrigerant exchanges heat with the domestic water in the domestic hot water circuit in the domestic hot water heat exchanger 61, the domestic water is heated, and the high-temperature refrigerant releases part of the heat and becomes medium-temperature refrigerant, which successively passes through the sixth refrigerant port 612, the third reversing valve 93, the first valve port 911, the second valve port 912 and the third refrigerant port 511 and reaches the outdoor heat exchanger 51. The medium-temperature refrigerant exchanges heat with the ambient air in the outdoor heat exchanger 51, continues to release the remaining part of the heat and becomes low-temperature refrigerant. The low-temperature refrigerant successively passes through the fourth refrigerant port 512, the enthalpy increasing module 80 and the liquid accumulator 70 and the first refrigerant port 31 and reaches the indoor heat exchanger 30. The low-temperature refrigerant exchanges heat with the hot water in the terminal water circuit in the indoor heat exchanger 30, absorbs heat to become high-temperature refrigerant, and the hot water is cooled to make the terminal device 2 realize refrigeration function. The high-temperature refrigerant after absorbing heat successively passes through the second refrigerant port 32, the fourth valve port 914, the third valve port 913, the gas-liquid separator 22 and returns to the compressor 21, realizing refrigerant circulation.

[0117] As shown in Figure 9, in another cooling and waste heat recovery mode for domestic hot water production, the first valve port 911 is connected to the second valve port 912. The third valve port 913 is connected to the fourth valve port 914. The fifth valve port 921 is connected to the sixth valve port 922. The eighth valve port 931 is connected to the ninth valve port 932. The other valve ports of the first reversing valve 91, the second reversing valve 92, and the third reversing valve 93 are all closed. At this time, the compressor 21 outputs high-temperature refrigerant, a portion of which passes through the fifth valve port 921 and the seventh valve port 923 sequentially into the first reversing valve 91. Another portion passes through the fifth valve port 921, the sixth valve port 922, and the fifth refrigerant port 611 into the domestic hot water heat exchanger 61. This portion of high-temperature refrigerant exchanges heat with the domestic water in the domestic hot water circuit within the domestic hot water heat exchanger 61, heating the domestic water and causing the high-temperature refrigerant to release some heat and become medium-temperature refrigerant. The medium-temperature refrigerant passes sequentially through the ninth valve port 932 and the eighth valve port 931, entering the first reversing valve 91 to merge the two refrigerant paths. The remaining refrigerant then passes sequentially through the first valve port 911, the second valve port 912, and the third refrigerant port 511 into the outdoor heat exchanger 51. The mixed refrigerant exchanges heat with the outside air in the outdoor heat exchanger 51, releasing the remaining heat and becoming a low-temperature refrigerant. The low-temperature refrigerant then passes sequentially through the fourth refrigerant port 512, the enthalpy-increasing module 80, the liquid storage tank 70, and the first refrigerant port 31, reaching the indoor heat exchanger 30. In the indoor heat exchanger 30, the low-temperature refrigerant exchanges heat with the hot water in the terminal water circuit, absorbing heat to form a high-temperature refrigerant. The cooling of the hot water enables the terminal device 2 to achieve its cooling function. The high-temperature refrigerant, after absorbing heat, passes sequentially through the second refrigerant port 32, the fourth valve port 914, the third valve port 913, and the gas-liquid separator 22 back to the compressor 21, completing the refrigerant cycle.

[0118] It's important to understand that in the "cooling and total heat recovery for domestic hot water production mode," all the heat from the high-temperature refrigerant is used to produce domestic hot water, achieving heat recovery and avoiding resource waste. This mode is suitable for the initial startup phase of the air source heat pump unit 1. However, in the two "cooling and waste heat recovery for domestic hot water production modes," a portion of the heat from the high-temperature refrigerant is used to produce domestic hot water, while a portion is released through the outdoor heat exchanger 51. This mode is suitable for the later startup phase of the air source heat pump unit 1, when the water in the domestic hot water circuit has already been heated to a certain temperature, eliminating the need for all the refrigerant's heat to be used for heating domestic water.

[0119] As shown in Figure 10, in heating and domestic hot water production modes, the first valve port 911 is connected to the fourth valve port 914. The second valve port 912 is connected to the third valve port 913. The fifth valve port 921 is connected to the sixth valve port 922. The eighth valve port 931 is connected to the ninth valve port 932. The other valve ports of the first reversing valve 91, the second reversing valve 92, and the third reversing valve 93 are all closed. At this time, the high-temperature refrigerant output by the compressor 21 passes through the second reversing valve 92 and the fifth refrigerant port 611 in sequence, and enters the domestic hot water heat exchanger 61. The high-temperature refrigerant exchanges heat with the domestic water in the domestic hot water circuit in the domestic hot water heat exchanger 61, and the domestic water is heated. The high-temperature refrigerant releases some heat and becomes medium-temperature refrigerant. The medium-temperature refrigerant passes through the sixth refrigerant port 612, the third reversing valve 93, the first valve port 911, the fourth valve port 914, and the second refrigerant port 32 in sequence, and enters the indoor heat exchanger 30. In the indoor heat exchanger 30, the medium-temperature refrigerant exchanges heat with the water in the terminal water circuit. The medium-temperature refrigerant releases heat and becomes low-temperature refrigerant, while the water in the terminal water circuit absorbs heat and rises in temperature, enabling the terminal device 2 to perform its heating function. After releasing heat, the low-temperature refrigerant sequentially passes through the first refrigerant port 31, the liquid storage tank 70, the enthalpy-increasing module 80, and the fourth refrigerant port 512 before entering the outdoor heat exchanger 51. In the outdoor heat exchanger 51, the low-temperature refrigerant exchanges heat with the outside air and absorbs heat, becoming high-temperature refrigerant. The high-temperature refrigerant sequentially passes through the third refrigerant port 511, the second valve port 912, the third valve port 913, and the gas-liquid separator 22 before returning to the compressor 21, thus completing the refrigerant circulation.

[0120] As shown in Figure 11, in another heating and domestic hot water production mode, the first valve port 911 is connected to the fourth valve port 914. The second valve port 912 is connected to the third valve port 913. The fifth valve port 921 is connected to the sixth valve port 922.

The other valve ports of the first reversing valve 91, the second reversing valve 92, and the third reversing valve 93 are all closed. At this time, a portion of the high-temperature refrigerant output by the compressor 21 directly enters the first reversing valve 91 through the fifth valve port 921 and the seventh valve port 923. The remaining portion of the refrigerant passes sequentially through the fifth valve port 921, the sixth valve port 922, and the fifth refrigerant port 611, entering the domestic hot water heat exchanger 61. This portion of high-temperature refrigerant exchanges heat with the domestic water in the domestic hot water circuit within the domestic hot water heat exchanger 61, heating the domestic water and causing the high-temperature refrigerant to release some heat and become medium-temperature refrigerant. The medium-temperature refrigerant sequentially passes through the sixth refrigerant port 612 and the third reversing valve 93 into the first reversing valve 91, where it merges with the high-temperature refrigerant that directly enters the first reversing valve 91. The refrigerant then sequentially passes through the first valve port 911, the fourth valve port 914, and the second refrigerant port 32 before entering the indoor heat exchanger 30. Within the indoor heat exchanger 30, the mixed refrigerant exchanges heat with the water in the terminal water circuit, releasing heat and becoming a low-temperature refrigerant. The water in the terminal water circuit absorbs heat and heats up, enabling the terminal device 2 to perform its heating function. The low-temperature refrigerant, after releasing heat, sequentially passes through the first refrigerant port 31, the liquid storage tank 70, the enthalpy-increasing module 80, and the fourth refrigerant port 512 before entering the outdoor heat exchanger 51. Within the outdoor heat exchanger 51, the low-temperature refrigerant exchanges heat with the outside air, absorbing heat and becoming a high-temperature refrigerant. The high-temperature refrigerant passes sequentially through the third refrigerant port 511, the second valve port 912, the third valve port 913, and the gas-liquid separator 22 before returning to the compressor 21, thus realizing the refrigerant circulation.

At this time, the high-temperature refrigerant output by the compressor 21 passes through the second reversing valve 92 and the fifth refrigerant port 611 in sequence, and enters the domestic hot water heat exchanger 61. In the domestic hot water heat exchanger 61, the high-temperature refrigerant exchanges heat with the domestic water in the domestic hot water circuit, and the domestic water is heated. The high-temperature refrigerant releases all its heat and becomes low-temperature refrigerant. The low-temperature refrigerant passes through the sixth refrigerant port 612, the third reversing valve 93, the liquid storage tank 70, the enthalpy-increasing module 80, and the fourth refrigerant port 512 in sequence, and enters the outdoor heat exchanger 51. In the outdoor heat exchanger 51, the low-temperature refrigerant exchanges heat with the outside air and absorbs heat, becoming high-temperature refrigerant. The high-temperature refrigerant passes sequentially through the third refrigerant port 511, the second valve port 912, the third valve port 913, and the gas-liquid separator 22 before returning to the compressor 21, thus realizing the refrigerant circulation.

[0122] As shown in Figure 13, in pure cooling mode, the first valve port 911 is connected to the second valve port 912. The third valve port 913 is connected to the fourth valve port 914. The fifth valve port 921 is connected to the seventh valve port 923.

At this time, the high-temperature refrigerant output by the compressor 21 passes sequentially through the second reversing valve 92, the first valve port 911, the second valve port 912, and the third refrigerant port 511, and enters the outdoor heat exchanger 51. The high-temperature refrigerant exchanges heat with the outside air in the outdoor heat exchanger 51, releasing heat and becoming low-temperature refrigerant. The low-temperature refrigerant passes sequentially through the fourth refrigerant port 512, the enthalpy-increasing module 80, the liquid receiver 70, and the first refrigerant port 31, and enters the indoor heat exchanger 30. The low-temperature refrigerant exchanges heat with the water in the terminal water circuit within the indoor heat exchanger 30, absorbing heat and becoming a high-temperature refrigerant. The water in the terminal water circuit releases heat, thus achieving the cooling function of the terminal device 2. The low-temperature refrigerant then passes sequentially through the second refrigerant port 32, the fourth valve port 914, the third valve port 913, and the gas-liquid separator 22 back to the compressor 21, thus achieving refrigerant circulation.

[0123] As shown in Figure 14, in pure heating mode, the first valve port 911 is connected to the fourth valve port 914. The second valve port 912 is connected to the third valve port 913. The fifth valve port 921 is connected to the seventh valve port 923.
