Abstract

This article provides a heat pump device, including: a chassis; a spirally arranged shell-and-tube heat exchanger disposed on the chassis; a compressor located above the shell-and-tube heat exchanger; and an integrated valve island, including an integrated body having a refrigerant flow path. The integrated valve island is at least partially disposed inside the area enclosed by the shell-and-tube heat exchanger, or the integrated valve island is completely located between the shell-and-tube heat exchanger and the compressor. This heat pump device utilizes the space inside the area enclosed by the shell-and-tube heat exchanger to accommodate the integrated valve island, or utilizes the space between the shell-and-tube heat exchanger and the compressor to accommodate the integrated valve island. This reduces the space occupied by the integrated valve island inside the shell-and-tube heat exchanger and outside the area between the shell-and-tube heat exchanger and the compressor within the heat pump device. This results in a more compact structure for the heat pump device, requiring less volume in the area inside the shell-and-tube heat exchanger and outside the area between the shell-and-tube heat exchanger and the compressor, thus facilitating miniaturization of the heat pump device.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0019] The integrated valve island provided in the embodiments of this application, such as Figures 1 to 6 As shown, it includes: an integrated body 100, which has a refrigerant flow path, including interfaces A, B, C, D1, D2, E1, E2, F, G, H1, H2, M1, M2, J, K, a first flow channel 110, a second flow channel 120, a third flow channel 130, and a fourth flow channel 140. Interfaces A and K are connected to the first flow channel 110, interfaces B and J are connected to the second flow channel 120, interfaces C and F are connected to the third flow channel 130, interfaces G, H1, and H2 are connected to the fourth flow channel 140, and interfaces D1 and D2 are connected to the fourth flow channel 140. The interfaces are connected as follows: E1 and E2 are connected, and M1 and M2 are connected. Interfaces F and G are configured to connect to the first and second interfaces of the first throttling component 210, respectively; interfaces H1 and M1 are configured to connect to the first and second interfaces of the second throttling component 220, respectively; interfaces H2 and J are configured to connect to the first and second interfaces of the first heat exchange channel 231 of the third heat exchanger 230, respectively; interfaces M2 and K are configured to connect to the first and second interfaces of the second heat exchange channel 232 of the third heat exchanger 230, respectively; and interfaces D2 and E2 are configured to connect to the first and second interfaces of the gas-liquid separator 240, respectively.

[0020] The integrated valve island includes an integrated body 100 with refrigerant flow paths, including interfaces A, B, C, D1, D2, E1, E2, F, G, H1, H2, M1, M2, J, K, a first flow channel 110, a second flow channel 120, a third flow channel 130, and a fourth flow channel 140. This allows the gas-liquid separator 240, the first throttling component 210, the second throttling component 220, and the third heat exchanger 230 to pass through the integrated body 100. The gas-liquid separator 240, the first throttling component 210, the second throttling component 220, and the third heat exchanger 230 are connected to other components of the heat pump equipment through the integrated body 100. This eliminates the need for some connecting pipes inside the heat pump equipment. Compared to eliminating these connecting pipes, the integrated body 100 occupies less space. Therefore, when the integrated body 100 is applied to heat pump equipment, the structure of the heat pump equipment is simpler, the number of connecting pipes is fewer, the space occupied is smaller, and the assembly efficiency is higher.

[0021] In some embodiments, such as Figure 2 and Figure 3 As shown, interfaces A, B, C, D1, E1, H1, M1, F, and G are located on the first side of the body 100 (as shown above), while interfaces D2, E2, H2, M2, J, and K are located on the second side of the body 100 (as shown below). Thus, the gas-liquid separator 240, the first throttling component 210, the second throttling component 220, and the third heat exchanger 230 are connected through the integrated body 100. The larger gas-liquid separator 240 and the third heat exchanger 230 are located on the second side of the body 100 (as shown below), while the smaller first throttling component 210 and the second throttling component 220 are located on the first side of the body 100 (as shown above). This combined structure is more compact and occupies less space. When applied to heat pump equipment, this structure results in a more compact heat pump system with a smaller footprint.

[0022] In some embodiments, such as Figure 9 As shown, the integrated valve island also includes a filter element 250, which is located between the H1 interface and the fourth flow channel 140. The filter element 250 may be a filter screen or similar structure.

[0023] In some embodiments, such as Figure 1 , Figure 5 , Figure 6 and Figure 9 As shown, the integrated valve island also includes a first throttling component 210, a second throttling component 220, a third heat exchanger 230, and a gas-liquid separator 240. The first throttling component 210, the second throttling component 220, the third heat exchanger 230, and the gas-liquid separator 240 are all connected to the main body 100 and also connected to the refrigerant flow path. Specifically, interfaces F and G can be connected to the first and second interfaces of the first throttling component 210, respectively; interfaces H1 and M1 can be connected to the first and second interfaces of the second throttling component 220, respectively; interfaces H2 and J can be connected to the first and second interfaces of the first heat exchange channel 231 of the third heat exchanger 230, respectively; interfaces M2 and K can be connected to the first and second interfaces of the second heat exchange channel 232 of the third heat exchanger 230, respectively; and interfaces D2 and E2 can be connected to the first and second interfaces of the gas-liquid separator 240, respectively. The enthalpy injection path in the heat pump equipment includes a second heat exchange passage 232 and a second throttling component 220 in the third heat exchanger 230. The enthalpy injection path is used to enhance the low-temperature heating capacity of the heat pump equipment. Alternatively, the third heat exchanger 230 can be configured as a plate heat exchanger.

[0024] The heat pump equipment provided in the embodiments of this application, such as Figures 7 to 9As shown, the system includes a compressor 310, a four-way valve 320, a second heat exchanger 330, and an integrated valve island as described in any of the above embodiments. The four-way valve 320 has a first port 321, a second port 322, a first switching port 323, and a second switching port 324. One of the first port 321 and the second port 322 of the four-way valve 320 is connected to either the first switching port 323 or the second switching port 324. The other of the first port 321 and the second port 322 of the four-way valve 320 is connected to either the first switching port 323 or the second switching port 324. Another connection in 24 is as follows: A interface is connected to the enthalpy injection port of compressor 310; B interface is connected to the first interface of the first heat exchanger; the first switching port 323 is connected to the second interface of the first heat exchanger; the second switching port 324 is connected to the first interface of the second heat exchanger 330; C interface is connected to the second interface of the second heat exchanger 330; D1 interface is connected to the first interface of compressor 310; the second interface of compressor 310 is connected to the first interface 321 of four-way valve 320; and the second interface 322 of four-way valve 320 is connected to E1 interface.

[0025] This heat pump device possesses all the advantages of the integrated valve island provided in any of the above embodiments, which will not be repeated here. The heat pump device using this integrated valve island has a simpler structure, fewer connecting pipes, smaller footprint, and higher assembly efficiency. The second heat exchanger 330 is a condenser.

[0026] In some examples, such as Figure 7 and Figure 8 As shown, the heat pump equipment also includes: a chassis 340; and a first heat exchanger 350. The first heat exchanger 350 is disposed on the chassis 340 and has a first heat exchange channel 351 and a second heat exchange channel 352. Interface B is connected to the first interface of the first heat exchange channel 351 of the first heat exchanger 350, and a first switching port 323 is connected to the second interface of the first heat exchange channel 351 of the first heat exchanger 350. This heat pump equipment is the outdoor unit of a heat pump water heater. The second heat exchange channel 352 of the first heat exchanger 350 is configured to circulate and connect with the indoor heating pipes, thereby achieving cooling or heating of the indoor environment. The first heat exchanger 350 is a spirally arranged shell-and-tube heat exchanger.

[0027] In some embodiments, such as Figure 7 and Figure 8As shown, the integrated valve island is at least partially located inside the area enclosed by the shell-and-tube heat exchanger (i.e., the first heat exchanger 350). The space inside the area enclosed by the shell-and-tube heat exchanger is used to accommodate the integrated valve island, thereby reducing the space occupied by the integrated valve island in the area outside the shell-and-tube heat exchanger inside the heat pump equipment. This makes the structure of the heat pump equipment more compact, and the volume required in the area outside the shell-and-tube heat exchanger inside the heat pump equipment is smaller, which is more conducive to the miniaturization design of the heat pump equipment.

[0028] It is possible that the lower part of the integrated valve island is located inside the area enclosed by the shell and tube heat exchanger (such as the third heat exchanger 230 and the gas-liquid separator 240 being located inside the area enclosed by the shell and tube heat exchanger), and the upper part of the integrated valve island is located above the area enclosed by the shell and tube heat exchanger (such as the body 310, the first throttling component 210 and the second throttling component 220 being located above the area enclosed by the shell and tube heat exchanger). Alternatively, the integrated valve island can be entirely located inside the area enclosed by the shell-and-tube heat exchanger. In this scheme, the projection of the integrated valve island from top to bottom falls completely inside the area enclosed by the shell-and-tube heat exchanger. At this time, the size of the integrated valve island is smaller than the size of the inner area enclosed by the shell-and-tube heat exchanger. By setting the integrated valve island in the middle of the inner side of the area enclosed by the shell-and-tube heat exchanger, sufficient space can be reserved in all directions of the integrated valve island for installation, fixing, disassembly, maintenance, and other operations, as well as space to maintain system reliability. Moreover, this installation method of the integrated valve island can effectively simplify the layout of internal components of the heat pump equipment, reduce the length of connecting pipes, and improve the assembly efficiency of the heat pump equipment. All of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be repeated here, and should all fall within the protection scope of this application.

[0029] In other embodiments, the compressor 310 is located above the shell-and-tube heat exchanger (i.e., the first heat exchanger 350), and the integrated valve island is located entirely between the compressor 310 and the shell-and-tube heat exchanger (i.e., the first heat exchanger 350). The space between the shell-and-tube heat exchanger (i.e., the first heat exchanger 350) and the compressor 310 is used to accommodate the integrated valve island, thereby reducing the space occupied by the integrated valve island in the area outside the shell-and-tube heat exchanger (i.e., the first heat exchanger 350) and the compressor 310 in the heat pump equipment. This makes the structure of the heat pump equipment more compact, and the volume required in the area outside the shell-and-tube heat exchanger and the compressor 310 in the heat pump equipment is smaller, which is more conducive to the miniaturization design of the heat pump equipment.

[0030] When the distance between the shell-and-tube heat exchanger and the compressor 310 exceeds the required installation height of the integrated valve island, or when the size of the integrated valve island cannot be reliably installed inside the area enclosed by the shell-and-tube heat exchanger, the integrated valve island is fixed above the shell-and-tube heat exchanger, ensuring that the integrated valve island is completely positioned above the shell-and-tube heat exchanger. In this case, the integrated valve island and the shell-and-tube heat exchanger do not overlap in the vertical direction (that is, viewed from the side, the integrated valve island and the shell-and-tube heat exchanger do not overlap vertically). This installation method effectively utilizes the shell-and-tube heat exchanger as a support, reducing additional support components and effectively improving the assembly efficiency of the heat pump equipment.

[0031] In some examples, a liquid storage tank or other structure may be provided inside the area enclosed by the shell-and-tube heat exchanger, which can also achieve the purpose of this application. The purpose of this application does not deviate from the design concept of this utility model, and will not be elaborated here. It should also fall within the protection scope of this application.

[0032] It can be that the integrated valve island is fixedly connected to the shell-and-tube heat exchanger; or it can be that the integrated valve island is fixed to the chassis by a bracket, etc.; both of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model, so they will not be described in detail here, and all should fall within the protection scope of this application.

[0033] In some embodiments, such as Figure 7 As shown, the main body has a first mounting bracket 150, and the shell-and-tube heat exchanger has a second mounting bracket 353. The first mounting bracket 150 and the second mounting bracket 353 are fixedly connected. To facilitate the connection between the first mounting bracket 150 and the second mounting bracket 353 and to facilitate maintenance, the first mounting bracket 150 and the second mounting bracket 353 are fixedly connected at the upper part of the shell-and-tube heat exchanger and are fixedly connected by screws screwed from top to bottom.

[0034] In some embodiments, such as Figure 7 As shown, the four-way valve 320 is located on the compressor 310. Both the compressor 310 and the four-way valve 320 are located above the shell-and-tube heat exchanger (i.e., the first heat exchanger 350) and the integrated valve island. This makes the distance between the gas-liquid separator 240, the four-way valve 320, the body 100 and the compressor 310 closer, and the length of the connecting pipe required between the gas-liquid separator 240, the four-way valve 320, the body 100 and the compressor 310 is shorter, which is also conducive to the miniaturization design of the heat pump equipment.

[0035] In some embodiments, such as Figure 1 , Figure 5 and Figure 9 As shown, the first throttling component 210 and the second throttling component 220 are electronic expansion valves or capillary tubes, etc.

[0036] like Figure 9As shown, the heat pump equipment operates in a cooling mode. The refrigerant flows from the second port of the compressor 310 through the first port 321 of the four-way valve 320, the second switching port 324 of the four-way valve 320, the second heat exchanger 330, the C port, the third flow channel 130, the F port, the first throttling component 210, and the G port into the fourth flow channel 140. Then, it flows through the H2 port, the first heat exchange flow channel 231 of the third heat exchanger 230, the J port, the second flow channel 120, the B port, the first heat exchange flow channel 351 of the first heat exchanger 350, the first switching port 323 of the four-way valve 320, the second port 322 of the four-way valve 320, the E1 port, the E2 port, the gas-liquid separator 240, the D2 port, and the D1 port to the first port of the compressor 310.

[0037] like Figure 9 As shown, the heat pump equipment operates in heating mode. Refrigerant flows from the second port of compressor 310 through the first port 321 of four-way valve 320, the first switching port 323 of four-way valve 320, the first heat exchange channel 351 of first heat exchanger 350, port B, the second channel 120, port J, and the first heat exchange channel 231 of third heat exchanger 230 to port H2. Then, it is split through the fourth channel 140: a portion of the refrigerant flows through port G, the first throttling component 210, port F, the third channel 130, port C, the second heat exchanger 330, and the four-way valve... The refrigerant flows from the second switching port 324 of valve 320, the second interface 322 of four-way valve 320, interface E1, interface E2, gas-liquid separator 240, interface D2, interface D1 to the first interface of compressor 310; another part of the refrigerant flows from the filter 250, interface H1, second throttling component 220, interface M1, interface M2, second heat exchange channel 232, interface K, first channel 110, interface A of third heat exchanger 230 to the enthalpy injection port of compressor 310, replenishing the compressor 310 with gas and increasing its enthalpy, thereby improving the low-temperature heating capacity of compressor 310.

[0038] In summary, the technical solution provided in this application embodiment has a shell-and-tube heat exchanger located on a chassis, a compressor located above the shell-and-tube heat exchanger, and an integrated valve island located at least partially inside the area enclosed by the shell-and-tube heat exchanger, or the integrated valve island located entirely between the shell-and-tube heat exchanger and the compressor. The integrated valve island is accommodated by utilizing the space inside the area enclosed by the shell-and-tube heat exchanger, or by utilizing the space between the shell-and-tube heat exchanger and the compressor. This reduces the space occupied by the integrated valve island inside the shell-and-tube heat exchanger and outside the area between the shell-and-tube heat exchanger and the compressor in the heat pump equipment. As a result, the structure of the heat pump equipment is more compact, and the required volume inside the shell-and-tube heat exchanger and outside the area between the shell-and-tube heat exchanger and the compressor is smaller, which is more conducive to the miniaturization design of the heat pump equipment.
