[0039] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0040] like Figures 1 to 5 As shown, an outdoor unit 1 according to an embodiment of the present invention may include a housing 10 , a compressor module 20 installed in the housing 10 , a domestic hot water heat exchange module 40 , and a control module 100 .

[0041] The shell 10 defines an inner cavity for accommodating the compressor module 20 , the domestic hot water heat exchange module 40 and the control module 100 installed in the shell 10 .

[0042] The compressor module 20 is connected to other devices to form a refrigerant circulation path, which is used to be connected to a terminal device (not shown in the figure) to form a refrigerant circulation loop. When the outdoor unit 1 is connected to the terminal device, the refrigerant flowing to the terminal device can exchange heat with the outside through the terminal device to achieve the cooling and heating functions of the terminal device.

[0043] The domestic hot water heat exchange module 40 is connected to the compressor module 20 and other devices to form a domestic hot water circulation loop for heating domestic water. The domestic hot water heat exchange module 40 is used to perform heat exchange with the refrigerant circulation loop in the domestic hot water circulation loop, thereby achieving heating of domestic hot water.

[0044] The control module 100 is electrically connected to the compressor module 20 and the domestic hot water heat exchange module 40 respectively, and is used to control the opening and closing of each module and the operation of the outdoor unit 1.

[0045] Specifically, the housing 10 includes a shell 11 and a chassis 12. The shell 11 defines an inner cavity, and an opening is formed at one end thereof to connect the inner cavity with the outside, and the chassis 12 is sealed on the opening. In the housing 10, the compressor module 20, the domestic hot water heat exchange module 40 and the control module 100 are installed on the chassis 12.

[0046] The chassis 12 can be divided into a first installation area 121, a second installation area 122 and a third installation area 123. The first installation area 121 is close to or in the middle of the chassis 12, and the second installation area 122 and the third installation area 123 are located on opposite sides of the first installation area 121 respectively.

[0047] The compressor module 20 is installed in the first installation area 121 , the domestic hot water heat exchange module 40 is installed in the second installation area 122 , and the control module 100 is installed in the third installation area 123 .

[0048] The modules are integrated in the housing 10 and arranged in different installation areas on the chassis 12, forming an outdoor unit chassis layout structure that is conducive to balancing the weight of the outdoor unit 1, and avoiding the problem of weight imbalance caused by heavy equipment being concentrated in a certain place on the chassis 12. In addition, the stability of the outdoor unit 1 during handling, transportation, and installation can be avoided, and the problems of shaking, tipping, bumping, etc. caused by unstable center of gravity can be avoided.

[0049] In this embodiment, the housing 10 is in a cubic shape, and the chassis 12 is in a longitudinally long rectangular shape, so that the second installation area 122 , the first installation area 121 , and the third installation area 123 are arranged in sequence along the length direction of the chassis 12 .

[0050] In some other optional embodiments, the housing 10 may be provided in other shapes, and the chassis 12 may be provided in other shapes such as a circle or an ellipse.

[0051] It should be understood that the shell 11 can be formed by detachably combining multiple plate-like structures or multiple plate-like structures and multiple rod-like structures, or can be integrally manufactured by integral molding, welding, etc.

[0052] like Figure 3 and Figure 4 As shown, in some embodiments, the compressor module 20 includes a compressor 21, a gas-liquid separator 22 and an oil separator 23. The gas-liquid separator 22 and the oil separator 23 are disposed on one side of the compressor 21.

[0053] In this embodiment, the oil separator 23 is disposed between the compressor 21 and the gas-liquid separator 22 , and the three extend substantially along the length direction of the chassis 12 , so as to further ensure the uniformity of the weight distribution of each device on the chassis 12 .

[0054] In some other optional embodiments, the compressor 21, the oil separator 23 and the gas-liquid separator 22 may be arranged adjacent to each other in a roughly triangular arrangement. Or the gas-liquid separator 22 and the oil separator 23 are located on both sides of the compressor 21, respectively. Or the gas-liquid separator 22 is located between the compressor 21 and the oil separator 23. Or when the compressor 21, the gas-liquid separator 22 and the oil separator 23 are arranged roughly linearly, they may not extend along the length direction of the chassis 12 (such as extending along the width direction of the chassis 12, or extending along the oblique direction, etc.).

[0055] Read also Figure 5 In some embodiments, the outdoor unit 1 further includes a liquid storage tank 30 . The liquid storage tank 30 is a part of the refrigerant flow path, installed on the chassis 12 , and disposed on the first installation area 121 or the second installation area 122 , and is connected to the compressor module 20 .

[0056] Specifically, in this embodiment, the liquid storage tank 30 is arranged in the first installation area 121, and is arranged on one side of the compressor 21 together with the gas-liquid separator 22 and the oil separator 23. In this way, at the position in the length direction of the chassis 12 where the compressor 21 is located, only one device, the compressor 21, is arranged in the width direction of the chassis 12, so that the large-sized compressor 21 is not concentrated together with other devices, which wastes other space of the chassis 12, thereby improving the integration of the outdoor unit 1 and realizing the miniaturization of the equipment.

[0057] Furthermore, the liquid storage tank 30 is located on one side of the gas-liquid separator 22 and the oil separator 23. Figure 3 Take the angle shown in FIG. 1 as an example. At this viewing angle, the long axis ( Figure 3 The axis L in the middle divides the chassis 12 into two parts, the gas-liquid separator 22 and the oil separator 23 are located in one part, and the liquid storage tank 30 is located in the remaining part. The compressor 21 spans the two parts.

[0058] Since the size and weight of the gas-liquid separator 22, the oil separator 23 and the liquid storage tank 30 are smaller than the compressor 21, the three can be arranged side by side in the width direction of the chassis 12 to further improve the utilization rate of the space of the chassis 12, while balancing the weight of the compressor 21 so that the weight of each device on the chassis 12 is evenly distributed.

[0059] In some other optional embodiments, the liquid storage tank 30 may be partially located in the first installation area 121 and partially located in the second installation area 122. The liquid storage tank 30 may also be installed in the third installation area 123.

[0060] like Figure 3 and Figure 5As shown, in some embodiments, the domestic hot water heat exchange module 40 includes a domestic hot water heat exchanger 41 and a water pump 42. The two are interconnected and are both located in the second installation area 122.

[0061] In this embodiment, the domestic hot water heat exchanger 41 is a shell-and-tube heat exchanger, which is disposed adjacent to the inner wall of the housing 10, and the water pump 42 is disposed on one side thereof. Specifically, the domestic hot water heat exchanger 41 and the water pump 42 are arranged adjacent to each other along the width direction of the chassis 12. Figure 3 In the angle shown, the water pump 42 is located on the long axis of the chassis 12 ( Figure 3 The domestic hot water heat exchanger 41 is distributed on one side of the long axis.

[0062] Specifically, the water pump 42 and the liquid storage tank 30 are located on the long axis ( Figure 3 The domestic hot water heat exchanger 41 is arranged adjacent to the gas-liquid separator 22.

[0063] In some other optional embodiments, the water pump 42 and the liquid storage tank 30 can also be respectively arranged on both sides of the long axis, that is, the water pump 42 is arranged adjacent to the gas-liquid separator 22, and the domestic hot water heat exchanger 41 is arranged adjacent to the liquid storage tank 30.

[0064] In some other optional embodiments, the water pump 42 and the domestic hot water heat exchanger 41 may also be arranged adjacent to each other along the length direction of the chassis 12. In this case, the water pump 42 may be arranged close to the first installation area 121, and the domestic hot water heat exchanger 41 may also be arranged close to the first installation area 121.

[0065] In some embodiments, the control module 100 may include an electric control box, a main control board installed in the electric control box, relays, reactors and other electrical components.

[0066] In this embodiment, the electric control box of the control module 100 is arranged in a long rectangular shape, the length of which is roughly matched with the width of the chassis 12, and is installed on the third installation area 123 in a direction in which the long axis of the horizontal cross section is perpendicular to the long axis of the chassis 12. The control module 100 is arranged adjacent to the compressor 21, and is located on a side of the compressor 21 away from the gas-liquid separator 22, the oil separator 23, and the liquid storage tank 30.

[0067] In some other optional embodiments, the control module 100 may also be arranged adjacent to the gas-liquid separator 22 and the liquid storage tank 30 , and the compressor 21 may be arranged adjacent to the domestic hot water heat exchanger 41 .

[0068] In some embodiments, the outdoor unit 1 further includes pipelines that connect various devices to each other to form a refrigerant flow passage and a domestic hot water circulation loop, and valves arranged on the pipelines.

[0069] Specifically, the valve includes at least one reversing valve, which can be connected to the compressor module 20 and / or the domestic hot water heat exchange module 40, so that a certain pipe section can have different conduction possibilities in different modes, thereby reducing the number and length of pipelines and further improving the miniaturization of the outdoor unit 1.

[0070] Furthermore, the reversing valve is located on the side of the liquid storage tank 30 corresponding to the first installation area 121. Together with the liquid storage tank 30, the weight of the gas-liquid separator 22 and the oil separator 23 is balanced to improve the uniformity of the weight distribution on both sides of the long axis of the chassis 12.

[0071] For example Figure 5 As shown, in this embodiment, the number of the reversing valves is three, which are now defined as the first reversing valve 70, the second reversing valve 80 and the third reversing valve 90. Among them, the first reversing valve 70 and the second reversing valve 80 are located above the liquid storage tank 30, and the two can effectively utilize the height difference between the liquid storage tank 30 and the gas-liquid separator 22 and the oil separator 23 to reduce the space occupied by the outdoor unit 1 in the horizontal direction. The third reversing valve 90 is located on one side of the liquid storage tank 30, and is respectively arranged adjacent to the liquid storage tank 30 and the compressor 21, further improving the miniaturization of the equipment. At the same time, the three reversing valves are all on the side where the liquid storage tank 30 is located.

[0072] like Figure 2 As shown, in some embodiments, the outdoor unit 1 further includes an outdoor heat exchange module 50, which is positioned in the housing 10. It is located above the first installation area 121 and the third installation area 123, that is, above the compressor module 20, the liquid storage tank 30 and the control module 100.

[0073] Furthermore, the outdoor heat exchange module 50 may include an outdoor heat exchanger 51 and a fan 52 .

[0074] In this embodiment, the outdoor heat exchanger 51 is a finned heat exchanger. It is roughly L-shaped, and the two side edges are respectively arranged adjacent to the two adjacent side walls of the shell 11. The outdoor heat exchanger 51 is located above the first installation area 121 and the third installation area 123, and the long side of the L-shape corresponds to the first installation area 121 and the third installation area 123 of the chassis 12, and the short side of the L-shape corresponds to the third installation area 123.

[0075] Furthermore, the outdoor heat exchange module 50 may also include a fan 52, which is disposed adjacent to the outdoor heat exchanger 51. When heating, the fan 52 draws the outside air into the housing 10 to exchange heat with the outdoor heat exchanger 51, so that the refrigerant inside the outdoor heat exchanger 51 absorbs the heat of the outside air; when cooling, the fan 52 blows the heat released by the outdoor heat exchanger 51 into the outside air.

[0076] In this embodiment, the fan 52 is located at a position half-enclosed by the L-shape of the outdoor heat exchanger 51 , and defines a rectangular space together with the outdoor heat exchanger 51 .

[0077] In some embodiments, the housing 10 may further include a water receiving pan 14 for supporting the outdoor heat exchange module 50. In the housing 10, the water receiving pan 14 is disposed below the outdoor heat exchange module 50, and the outdoor heat exchange module 50 is disposed above the compressor module 20 and the control module 100 through the water receiving pan 14.

[0078] In some other optional embodiments, the outdoor heat exchange module 50 may also be located only above the first installation area 121, or only above the third installation area 123. The outdoor heat exchanger 51 may also be configured in other shapes.

[0079] In some embodiments, the outdoor unit 1 further includes a water tank 60, which is located in the housing 10, fixedly supported on the chassis 12 by a support member, and located above the second installation area 122, that is, also located above the domestic hot water heat exchange module 40, avoiding interference with the domestic hot water heat exchange module 40. The water tank 60 belongs to the domestic hot water circulation loop, is connected to the domestic hot water heat exchanger 41 and the water pump 42, and stores domestic water inside, which is heated by the domestic hot water circulation loop for use by users.

[0080] Specifically, the outer surface of the water tank 60 can be wrapped with thermal insulation cotton to keep the water tank 60 warm.

[0081] In some embodiments, the outdoor unit 1 may further include a partition 13 , which is disposed between the water tank 60 and the outdoor heat exchange module 50 .

[0082] Specifically, the side of the partition 13 facing the bottom plate 12 can be connected to the water receiving tray 14, and the two are connected to form an L-shaped partition, and the inner cavity of the shell can also be divided into a rectangular cavity and an L-shaped cavity. The outdoor heat exchange module 50 is located in the rectangular cavity, the water tank 60 and the domestic hot water heat exchange module 40 are located in the long side of the L-shaped cavity, and the compressor module 20, the liquid storage tank 30 and the control module 100 are located in the short side of the L-shaped cavity.

[0083] It should be understood that the “shell heat exchanger” and “fin heat exchanger” mentioned are only examples and are not intended to limit the present application.

[0084] The present application will be further described below through the system conduction conditions of the outdoor unit 1 in various modes:

[0085] like Figure 6As shown, in some embodiments, the first reversing valve 70 includes a first valve port 71, a second valve port 72, and a third valve port 73. The second reversing valve 80 includes a fourth valve port 81, a fifth valve port 82, and a sixth valve port 83. The third reversing valve 90 includes a seventh valve port 91, an eighth valve port 92, a ninth valve port 93, and a tenth valve port 94.

[0086] The domestic hot water heat exchanger 41 includes a first refrigerant port 411, a second refrigerant port 412, a first water inlet port 413 and a first water outlet port 414. The outdoor heat exchanger 51 includes a third refrigerant port 511 and a fourth refrigerant port 512. The water tank 60 includes a second water inlet port 61 and a second water outlet port 62.

[0087] The inlet end of the oil separator 23 is connected to the outlet end of the compressor 21, and the outlet end is connected to the first valve port 71. Specifically, the oil separator 23 includes an oil separator body 231 and an oil return pipe 232. The inlet end of the oil separator body 231 is connected to the outlet end of the compressor 21, and is used to separate the lubricating oil from the compressor 21 mixed in the refrigerant. The two ends of the oil return pipe 232 are respectively connected to the oil separator body 231 and the inlet end of the compressor 21, and are used to return the separated lubricating oil to the compressor 21.

[0088] The second valve port 72 of the first reversing valve 70 is connected to the first refrigerant port 411 of the domestic hot water heat exchanger 41. The fifth valve port 82 of the second reversing valve 80 is connected to the first end of the liquid storage tank 30, and is connected to one end of the external terminal device through a pipeline. The sixth valve port 83 is connected to the second refrigerant port 412 of the domestic hot water heat exchanger 41. The seventh valve port 91 of the third reversing valve 90 is respectively connected to the third valve port 73 and the fourth valve port 81, the eighth valve port 92 is connected to the third refrigerant port 511 of the outdoor heat exchanger 51, the ninth valve port 93 is connected to the inlet end of the gas-liquid separator 22, and the tenth valve port 94 is used to connect to the other end of the external terminal device.

[0089] The fourth refrigerant port 512 of the outdoor heat exchanger 51 is communicated with the second end of the liquid storage tank 30. The outlet end of the gas-liquid separator 22 is communicated with the inlet end of the compressor 21.

[0090] The first water outlet port 414 of the domestic hot water heat exchanger 51 is connected to the second water inlet port 61 of the water tank 60. The second water outlet port 62 of the water tank 60 is connected to the first water inlet port 413 of the domestic hot water heat exchanger 51 through the water pump 42.

[0091] Among them, the compressor 21, the oil separator 23, the outdoor heat exchanger 51, the liquid storage tank 30, the gas-liquid separator 22, the first reversing valve 70, and the third reversing valve 90 are connected to the terminal device to form a refrigerant circuit to realize the cooling and heating functions of the terminal device.

[0092] like Figure 7 As shown, in the cooling mode only, the first valve port 71 is connected to the third valve port 73. The seventh valve port 91 is connected to the eighth valve port 92, and the ninth valve port 93 is connected to the tenth valve port 94. The other valve ports of the three reversing valves are closed. At this time, the high-temperature refrigerant passes through the oil separator 23, the first reversing valve 70, and the third reversing valve 90 through the compressor 21 to reach the outdoor heat exchanger 51, and exchanges heat with the outside air to become a low-temperature refrigerant. The low-temperature refrigerant passes from the outdoor heat exchanger 51 through the liquid storage tank 30 to the terminal device, and exchanges heat with the external environment through the terminal device to become a high-temperature refrigerant, realizing the refrigeration function of the terminal device. The high-temperature refrigerant then passes through the third reversing valve 90 and the gas-liquid separator 22 in turn and returns to the compressor 21 to realize the circulation of the refrigerant.

[0093] like Figure 8 As shown, in the heating-only mode, the first valve port 71 is connected to the third valve port 73. The seventh valve port 91 is connected to the tenth valve port 94, and the eighth valve port 92 is connected to the ninth valve port 93. The other valve ports of the three reversing valves are closed. At this time, the high-temperature refrigerant passes through the compressor 21 through the oil separator 23, the first reversing valve 70, and the third reversing valve 90 to reach the terminal device, and exchanges heat with the external environment through the terminal device to become a low-temperature refrigerant, thereby realizing the heating function of the terminal device. The low-temperature refrigerant then passes through the liquid storage tank 30 to reach the outdoor heat exchanger 51, exchanges heat with the outside air, and becomes a high-temperature refrigerant. The high-temperature refrigerant then passes through the third reversing valve 90 and the gas-liquid separator 22 in turn and returns to the compressor 21 to realize the refrigerant circulation.

[0094] like Figures 9 to 12 As shown, the compressor 21, the oil separator 23, the domestic hot water heat exchanger 41, the outdoor heat exchanger 51, the liquid storage tank 30, the gas-liquid separator 22, the first reversing valve 70, the second reversing valve 80, and the third reversing valve 90 are connected with the terminal device to form a refrigerant circuit. The domestic hot water heat exchanger 41, the water pump 42 and the water tank 60 are connected to form a domestic hot water circuit. In order to realize the cooling and heating functions of the terminal device, the domestic hot water is heated.

[0095] like Fig. 9As shown, in this refrigeration and waste heat recovery mode of domestic hot water, the first valve port 71 is connected to the second valve port 72. The fourth valve port 81 is connected to the sixth valve port 83. The seventh valve port 91 is connected to the eighth valve port 92, and the ninth valve port 93 is connected to the tenth valve port 94. The other valve ports of the three reversing valves are all closed. At this time, the high-temperature refrigerant enters the domestic hot water heat exchanger 41 from the compressor 21 through the oil separator 23 and the first reversing valve 70, and exchanges heat with the water in the domestic hot water circuit to become a medium-temperature refrigerant, thereby achieving the heating of domestic hot water. The medium-temperature refrigerant passes through the second reversing valve 80 and the third reversing valve 90 from the domestic hot water heat exchanger 41 in turn to reach the outdoor heat exchanger 51, exchanges heat with the outside air, and becomes a low-temperature refrigerant. The low-temperature refrigerant reaches the terminal device through the liquid storage tank 30, exchanges heat with the outside environment through the terminal device, absorbs heat and becomes a high-temperature refrigerant, thereby achieving the refrigeration function of the terminal device. The high-temperature refrigerant then passes through the third reversing valve 90 and the gas-liquid separator 22 in sequence and returns to the compressor 21, thereby realizing the circulation of the refrigerant.

[0096] like Fig.10 As shown, in this refrigeration and waste heat recovery mode for domestic hot water, the first valve port 71, the second valve port 72, and the third valve port 73 are all connected. The fourth valve port 81 is connected to the sixth valve port 83. The seventh valve port 91 is connected to the eighth valve port 92, and the ninth valve port 93 is connected to the tenth valve port 94. The other valve ports of the three reversing valves are all closed. At this time, the high-temperature refrigerant enters the domestic hot water heat exchanger 41 from the compressor 21 through the oil separator 23 and the first reversing valve 70, and part of it passes through the third reversing valve 90 to reach the outdoor heat exchanger 51. The high-temperature refrigerant entering the domestic hot water heat exchanger 41 exchanges heat with the water in the domestic hot water circuit and becomes a medium-temperature refrigerant to achieve the heating of domestic hot water. The medium-temperature refrigerant passes through the second reversing valve 80 and the third reversing valve 90 from the domestic hot water heat exchanger 41 to the outdoor heat exchanger 51, merges with the refrigerant that directly reaches the outdoor heat exchanger 51, exchanges heat with the outside air, and becomes a low-temperature refrigerant. The low-temperature refrigerant reaches the terminal device through the liquid storage tank 30, and exchanges heat with the external environment through the terminal device, absorbs heat and becomes high-temperature refrigerant, realizing the refrigeration function of the terminal device. The high-temperature refrigerant then passes through the third reversing valve 90 and the gas-liquid separator 22 in sequence and returns to the compressor 21, realizing the circulation of the refrigerant.

[0097] like Fig.11As shown, in this heating and domestic hot water mode, the first valve port 71 is connected to the second valve port 72. The fourth valve port 81 is connected to the sixth valve port 83. The seventh valve port 91 is connected to the tenth valve port 94, and the eighth valve port 92 is connected to the ninth valve port 93. The other valve ports of the three reversing valves are all closed. At this time, the high-temperature refrigerant passes through the compressor 21, the oil separator 23, and the first reversing valve 70 in turn into the domestic hot water heat exchanger 41, and exchanges heat with the water in the domestic hot water circuit to become a medium-temperature refrigerant, thereby achieving the heating of domestic hot water. The medium-temperature refrigerant passes through the second reversing valve 80 and the third reversing valve 90 from the domestic hot water heat exchanger 41 to reach the terminal device, and exchanges heat with the external environment through the terminal device to become a low-temperature refrigerant, thereby achieving the heating function of the terminal device. The low-temperature refrigerant then passes through the liquid storage tank 30 to reach the outdoor heat exchanger 51, exchanges heat with the outside air, and becomes a high-temperature refrigerant. The high-temperature refrigerant then passes through the third reversing valve 90 and the gas-liquid separator 22 in sequence and returns to the compressor 21, thereby realizing the circulation of the refrigerant.

[0098] like Fig.12 As shown, in this heating and domestic hot water mode, the first valve port 71, the second valve port 72, and the third valve port 73 are all connected. The fourth valve port 81 is connected to the sixth valve port 83. The seventh valve port 91 is connected to the tenth valve port 94, and the eighth valve port 92 is connected to the ninth valve port 93. The other valve ports of the three reversing valves are all closed. At this time, the high-temperature refrigerant passes through the oil separator 23 and the first reversing valve 70 in sequence through the compressor 21, and part of it enters the domestic hot water heat exchanger 41, and part of it passes through the third reversing valve 90 to reach the terminal device. The high-temperature refrigerant entering the domestic hot water heat exchanger 41 exchanges heat with the water in the domestic hot water circuit and becomes a medium-temperature refrigerant to achieve the heating of domestic hot water. The medium-temperature refrigerant passes through the third reversing valve 90 from the domestic hot water heat exchanger 41 to the terminal device, and merges with the refrigerant that directly passes through the third reversing valve 90 to reach the terminal device, and exchanges heat with the external environment through the terminal device to become a low-temperature refrigerant to achieve the heating function of the terminal device. The low-temperature refrigerant then passes through the liquid storage tank 30 to reach the outdoor heat exchanger 51, exchanges heat with the outside air, and becomes a high-temperature refrigerant. The high-temperature refrigerant then passes through the third reversing valve 90 and the gas-liquid separator 22 in sequence and returns to the compressor 21, thus realizing the circulation of the refrigerant.

[0099] like Fig.13 As shown, the compressor 21, the oil separator 23, the domestic hot water heat exchanger 41, the gas-liquid separator 22, the first reversing valve 70, the second reversing valve 80, and the third reversing valve 90 are connected with the terminal device to form a refrigerant circuit. The domestic hot water heat exchanger 41, the water pump 42 and the water tank 60 are connected to form a domestic hot water circuit. In order to realize the refrigeration function of the terminal device, the domestic hot water is heated.

[0100] Specifically, in this refrigeration and full heat recovery mode, the first valve port 71 and the second valve port 72 are connected. The fifth valve port 82 is connected to the sixth valve port 83. The ninth valve port 93 is connected to the tenth valve port 94. The other valve ports of the three reversing valves are closed. At this time, the high-temperature refrigerant enters the domestic hot water heat exchanger 41 through the compressor 21, passes through the oil separator 23 and the first reversing valve 70 in turn, exchanges heat with the water in the domestic hot water circuit, and becomes a low-temperature refrigerant to achieve the heating of domestic hot water. The low-temperature refrigerant enters the terminal device from the second reversing valve 80, exchanges heat with the external environment through the terminal device, and becomes a high-temperature refrigerant to achieve the refrigeration function of the terminal device. The high-temperature refrigerant then returns to the compressor 21 through the third reversing valve 90 and the gas-liquid separator 22 in turn to achieve the circulation of the refrigerant.

[0101] like Fig.14 As shown, the compressor 21, the oil separator 23, the domestic hot water heat exchanger 41, the liquid storage tank 30, the outdoor heat exchanger 51, the gas-liquid separator 22, the first reversing valve 70, the second reversing valve 80, and the third reversing valve 90 are connected to form a refrigerant circuit. The domestic hot water heat exchanger 41, the water pump 42 and the water tank 60 are connected to form a domestic hot water circuit. Only domestic water can be heated.

[0102] Specifically, in the domestic water heating mode only, the first valve port 71 and the second valve port 72 are connected. The fifth valve port 82 is connected to the sixth valve port 83. The eighth valve port 92 and the ninth valve port 93 are connected to each other. The other valve ports of the three reversing valves are closed. At this time, the high-temperature refrigerant enters the domestic hot water heat exchanger 41 through the compressor 21, passes through the oil separator 23 and the first reversing valve 70 in turn, exchanges heat with the water in the domestic hot water circuit, and becomes a low-temperature refrigerant to achieve the heating of domestic hot water. The low-temperature refrigerant enters the outdoor heat exchanger 51 through the second reversing valve 80 and the liquid storage tank 30 in turn, exchanges heat with the outside air, and becomes a high-temperature refrigerant. The high-temperature refrigerant then passes through the third reversing valve 90 and the gas-liquid separator 22 in turn and returns to the compressor 21 to achieve the circulation of the refrigerant.

[0103] It should be understood that in summer and other situations where the terminal equipment needs cooling, the outdoor unit 1 can use the full heat recovery mode (i.e. the aforementioned "cooling and full heat recovery mode") during the initial startup phase during operation. At this time, all the heat absorbed by the low-temperature refrigerant at the terminal equipment is used to heat domestic water.

[0104] After the outdoor unit 1 has been running for a period of time, the domestic hot water in the water tank 60 has reached a certain temperature. Therefore, it can be switched to the waste heat recovery mode (i.e., the two "refrigeration and waste heat recovery domestic hot water modes" mentioned above). At this time, part of the heat absorbed by the low-temperature refrigerant at the terminal device is used to heat domestic water, and part is released through heat exchange with the outside air through the outdoor heat exchanger 51.

[0105] In summary, the outdoor unit of the utility model integrates the compressor module 20, the liquid storage tank 30, the outdoor heat exchange module 50, the domestic hot water heat exchange module 40, the water tank 60, etc. into the housing 10 of the outdoor unit 1, and through reasonable arrangement in the housing 10, the length of the connecting pipes between the various devices of each module is reduced, and the entire outdoor unit 1 can complete multiple functions such as heating, cooling, and preparing domestic hot water. The high integration reduces the complexity of installing multiple devices during the engineering installation process and improves the user experience.
