Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a heat pump system. Background Art

[0002] With the global emphasis on energy conservation, emission reduction, and sustainable development, heat pump technology, as a highly efficient and energy-efficient heating and cooling solution, has experienced rapid development and widespread application. Shell-and-tube high-efficiency tank heat exchangers, with their efficient heat transfer capabilities, can improve the overall energy efficiency of heat pump systems, reduce energy consumption, and align with the development trend of green buildings and low-carbon living. The rational layout of shell-and-tube high-efficiency tank heat exchangers is particularly important in product design: a reasonable layout can effectively reduce the amount of copper pipes used and improve the removability of the equipment. For products with multiple systems, it can also improve the performance stability of each system.

[0003] Existing heat pump systems typically have four systems, located at the four corners of the system, with an electrical control cabinet in the center and a shell-and-tube high-efficiency tank heat exchanger located to one side of the water inlet. The high-efficiency tank heat exchanger is composed of four individual high-efficiency tanks welded together with two inlet and outlet water pipes to form a single unit. However, due to its location, the high-efficiency tank heat exchanger is always located far from one of the systems, resulting in a larger span of connected piping, which increases the length of the piping. Excessive piping also increases piping stress, the risk of refrigerant leakage, and costs. Furthermore, the varying distances between the systems and the casing can lead to deviations in the condensing temperatures of the four systems, impacting the performance stability and consistency of each system.

[0032] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0034] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] like Figure 1As shown, the utility model provides a heat pump system, including: a main body 1, an electric control cabinet 2 and a high-efficiency heat exchanger 3; an installation space is provided inside the main body 1; four heat pump units 11 are provided inside the main body 1; the four heat pump units 11 are respectively arranged at the four corners of the installation space; the electric control cabinet 2 is arranged in the gap between adjacent heat pump units 11; there are two electric control cabinets 2; the two electric control cabinets 2 are symmetrically arranged; the high-efficiency heat exchanger 3 is arranged in the installation space; specifically, the high-efficiency heat exchanger 3 is arranged on the inner side of the four heat pump units 11, and the high-efficiency heat exchanger 3 is suitable for heat exchange with the heat pump unit 11; the heat exchanger includes four high-efficiency tank bodies 31 and a heat exchange pipeline 32 arranged along the extension direction of the heat dissipation space; the four high-efficiency tank bodies 31 are respectively arranged on one side of the four heat pump units 11; the four high-efficiency tank bodies 31 are symmetrically arranged with each other.

[0037] It should be noted that the four high-efficiency tanks 31 can be symmetrically arranged along the transverse centerline of the main body 1, or symmetrically arranged along the vertical centerline. In this embodiment, they are symmetrically arranged along both the transverse centerline and the vertical centerline of the main body 1. Furthermore, because the four high-efficiency tanks 31 are symmetrically arranged, each tank is at the same distance from the heat pump unit 11, thereby ensuring the heat exchange effect of each high-efficiency tank 31. Furthermore, since the distances are the same, installation is facilitated and no additional fool-proofing design is required.

[0038] It should be noted that the electric control cabinet 2 is arranged in the gap between adjacent heat pump units 11; the high-efficiency heat exchanger 3 is arranged in the heat dissipation space vacant in the middle of the installation space, and the four high-efficiency tanks 31 are all arranged on one side of the heat pump unit 11 and symmetrically arranged with each other, which can ensure that each high-efficiency tank 31 is at the same distance from its adjacent heat pump unit 11, thereby preventing the condensation temperature between the four heat pump units 11 from being different due to different distances, thereby ensuring the performance stability and consistency of each system.

[0039] It should be noted that there are three electric control cabinets 2 in the prior art. In this solution, the three electric control cabinets 2 are combined into two, thereby freeing up space for the high-efficiency radiator.

[0040] It should be noted that in this solution, the length of the heat exchange pipe 32 is appropriately increased, and the high-efficiency tank 31 is positioned closest to the corresponding heat dissipation unit. The top of the high-efficiency tank 31 is connected to the heat pump unit 11 via the refrigerant inlet pipe 311 and the refrigerant outlet pipe 312. Specifically, the heat from the heat pump unit 11 is dissipated by circulating water. It should be noted that the heat exchange pipe 32 passes through the transverse centerline of the main body.

[0041] It should be noted that the high-efficiency tank body 31 and the heat exchange pipeline 32 can be detachably connected or fixedly connected by welding, wherein the high-efficiency tank body 31 and the heat exchange pipeline 32 can also be fixedly connected by bonding or the like; wherein the high-efficiency tank body 31 and the heat exchange pipeline 32 can be directly connected by a flange structure 5 or other structures, thereby realizing a detachable connection; in order to increase convenience and reduce maintenance costs, by detachably connecting the high-efficiency tank body 31 and the heat exchange pipeline 32, a single high-efficiency tank body 31 can be replaced. When a single high-efficiency tank body 31 is damaged, only the damaged high-efficiency tank body 31 needs to be replaced. In the traditional high-efficiency heat exchanger 3, multiple high-efficiency tank bodies 31 are fixedly connected to the heat exchange pipeline 32. When a single high-efficiency tank body 31 is damaged, the entire high-efficiency heat exchanger 3 needs to be replaced, resulting in extremely high maintenance costs.

[0042] It should be noted that the high-efficiency tank body 31 and the heat exchange pipeline 32 are detachably connected. If sealing and cost are not taken into consideration, they can also be connected by snap fastening or magnetic attraction.

[0043] Furthermore, a connecting pipeline 6 is provided, one end of which is connected to the high-efficiency tank 31 , and the other end of which is connected to the heat exchange pipeline 32 .

[0044] like Figure 3 As shown, further, the high-efficiency tank body 31 is connected to the heat exchange pipeline 32 through a fire trench pipe clamp structure 4. Specifically, the fire trench pipe clamp structure 4 is arranged on the heat exchange pipeline 32, and each fire trench pipe clamp structure 4 is connected to the heat exchange pipeline 32 along the front and rear ends of the heat exchange pipeline 32. The left and right sides of each fire trench pipe clamp structure 4 are respectively connected to the heat exchange pipeline 32. Each heat exchange pipeline 32 is connected to the high-efficiency tank body 31, wherein the connecting pipe 6 is detachably connected to the fire trench pipe clamp structure 4, thereby realizing a detachable connection of the high-efficiency tank body 31.

[0045] The fire protection trench pipe clamp structure 4 connection has the advantage of fast installation. Using the fire protection trench pipe clamp structure 4 can greatly shorten the project cycle and reduce labor costs. It is also simple to maintain and very convenient to disassemble and assemble, which can save labor costs and time.

[0046] Furthermore, the device further includes a plurality of grooved square spools 7, each of which is disposed on the heat exchange pipeline 32. The high-efficiency tank 31 is detachably connected to the grooved square spools 7. It should be noted that the grooved square spools 7 are connected to the heat exchange pipeline 32 at both ends thereof and to two connecting pipelines 6 on the left and right sides.

[0047] It's important to note that fire protection grooved pipe clamps, as crucial connection components in fire protection systems, are designed to ensure a tight, stable, and pressure-resistant connection. A grooved clamp primarily consists of the following components: The clamp body: This is the main body of the grooved pipe clamp, typically made of high-strength metal (such as stainless steel or carbon steel), providing sufficient rigidity and toughness to withstand the pressure and tension of the pipe. The inner side of the clamp body is designed with grooves that align with the pipe groove, ensuring a tight fit. The sealing rubber ring: This acts as a seal between the pipe groove and the clamp body. Typically made of high-quality, elastic, and corrosion-resistant materials, the sealing rubber ring can accommodate even minor temperature-related deformations in the pipe while ensuring a tight seal at the connection. The fastening bolts: These secure the clamp body to the pipe, ensuring a stable and tight connection. These fastening bolts are typically installed on either side or on the top of the clamp body. Tightening the bolts secures the clamp body and sealing rubber ring to the pipe, enabling a quick connection. First, pre-machine a groove of a certain depth and width into the pipe. Then, place the rubber sealing ring over the pipe groove. Next, place the clamp onto the pipe, aligning the inner groove of the clamp with the pipe groove. Finally, tighten the fastening bolts until the clamp and rubber sealing ring are firmly attached to the pipe, achieving a quick connection.

[0048] It should be noted that the high-efficiency heat exchanger 3 is suitable for being detachably connected to an external water pump or other structure, and the cooling water is driven into the heat exchange pipeline 32 by the water pump or other structure.

[0049] like Figure 2 As shown, it should be noted that the use of the fire trench pipe clamp structure 4 requires the operator to master certain skills and has high requirements for the operator. As an alternative embodiment, the high-efficiency tank body 31 and the heat exchange pipeline 32 are connected via a flange structure 5. The flange structure 5 can also achieve a detachable connection between the high-efficiency tank body 31 and the heat exchange pipeline 32. The flange structure 5 is simple to operate and has low requirements for the operator. In addition, the flange structure 5 connection method uses a bolt fastening method to ensure a tight and leak-free connection.

[0050] Furthermore, when connected by flanges, the connecting pipe 6 also includes a first connecting pipe 61 and a second connecting pipe 62, one end of the first connecting pipe 61 is connected to the high-efficiency tank body 31, and the other end is welded to the heat exchange pipe 32, and the second connecting pipe 62 is arranged between the first connecting pipe 61 and the high-efficiency tank body 31, and the second connecting pipe 62 is detachably connected to the first connecting pipe 61; in this embodiment, one end of the first connecting pipe 61 is communicated with the heat exchange pipe 32, the other end of the first connecting pipe 61 is provided with a flange structure 5, and the end of the second connecting pipe 62 close to the first connecting pipe 61 is also provided with a flange structure 5, and the first connecting pipe 61 and the second connecting pipe 62 are connected by The flange structure 5 is detachably connected. As a replaceable embodiment, one end of the first connecting pipe 61 is connected to the heat exchange pipeline 32, and the other end of the first connecting pipe 61 is provided with a fire trench pipe clamp structure 4. The second connecting pipe 62 is also provided with a fire trench pipe clamp structure 4 at one end close to the first connecting pipe 61. The first connecting pipe 61 and the second connecting pipe 62 are detachably connected through the fire trench pipe clamp structure 4; it should be noted that the first connecting pipe 61 and the second connecting pipe 62 are detachably connected and are connected by assembly. When a component is damaged, it is convenient to directly replace the damaged component, which facilitates later maintenance and reduces maintenance costs.

[0051] It should be noted that the flange structure 5 is fixed to the end portion where the first connecting pipe 61 and the second connecting pipe 62 are connected by welding or the like, and the first connecting pipe 61 and the second connecting pipe 62 are detachably connected via the flange structure 5 .

[0052] It should be noted that the second connecting pipe 62 and the high-efficiency tank body 31 can also be detachably connected, and the detachable methods specifically include flange structure 5 or fire trench pipe clamp structure 4. In this embodiment, in order to reduce costs, the second connecting pipe 62 and the high-efficiency tank are fixedly connected by welding.

[0053] Specifically, the first connecting pipe 61 is vertically arranged to the heat dissipation pipe and the heat exchange pipe 32. By vertically arranging the first connecting pipe 61 to the heat exchange pipe 32, the length of the first connecting pipe 61 can be shortened to the maximum extent, thereby reducing material costs.

[0054] And the number of first connecting pipes 61 and second connecting pipes 62 corresponds to the number of the high-efficiency tank bodies 31. In this solution, there are eight first connecting pipes 61 and second connecting pipes 62, and four high-efficiency tank bodies 31. Each high-efficiency tank body 31 is provided with two first connecting pipes 61 and two second connecting pipes 62.

[0055] Furthermore, the lengths of each first connecting pipe 61 plus the connected second connecting pipe 62 are the same, thereby ensuring that the distances of the refrigerant from the high-efficiency tank 31 to the heat pump unit 11 are the same.

[0056] It should be noted that the first connecting tube 61 is vertically connected to the heat exchange pipeline 32; the first connecting tube 61 can be vertically connected to both sides of the heat exchange pipeline 32. Specifically, the first connecting tube 61 is disposed on one side of the heat exchange pipeline 32 and fixedly connected by welding or other means, with the other end of the first connecting tube 61 connected to the second connecting tube 62. As an alternative embodiment, the first connecting tube 61 can also be vertically connected to the top of the heat exchange pipeline 32. Specifically, the first connecting tube 61 is located above the heat exchange pipeline 32 and has an L-shape. One end of the first connecting tube 61 is fixedly connected to the top of the heat exchange pipeline 32 by welding or other means, and the other end of the first connecting tube 61 is connected to the second connecting tube 62.

[0057] Furthermore, a support member 100 is provided, connected to the heat exchange pipeline 32; there are a plurality of support members 100; and the support members 100 are suitable for supporting the heat exchange pipeline 32. In this embodiment, there are three support members 100, and the number of support members 100 can be reasonably increased or decreased according to the length of the heat exchange pipeline 32. Specifically, the support member 100 includes a support frame and a support sleeve. The support frame is fixed to the ground via bolts or other structures. The bottom of the support sleeve is fixedly connected to the support frame, and the support sleeve is provided on the outer surface of the heat exchange pipeline 32. The provision of the support member 100 can support the heat exchange pipeline 32, preventing the heat exchange pipeline 32 from bending due to the weight of the excessively long heat exchange pipeline 32, thereby posing a safety hazard.

[0058] Furthermore, one end of the heat exchange pipe 32 away from the water pump and other structures is blocked.

[0059] Furthermore, the heat exchange pipeline 32 includes a water inlet pipe 8 and a water outlet pipe 9 ; the water inlet pipe 8 is connected to the bottom of the high-efficiency tank body 31 ; the water outlet pipe 9 is connected to the top of the high-efficiency tank body 31 .

[0060] It should be noted that the two ends of the water inlet pipe 8 and the water outlet pipe 9 can be connected by welding. However, when one of the high-efficiency cans is damaged by welding, it is impossible to replace one of them separately. Therefore, the water inlet pipe 8 and the water outlet pipe 9 are detachably connected by means of a fire trench pipe clamp structure 4. When one of them is damaged, the connection with the fire trench pipe clamp structure 4 requires the operator to master certain skills, which places high demands on the operator. As an alternative embodiment, the two ends of the water inlet pipe 8 and the water outlet pipe 9 are connected by a flange structure 5. The detachable connection of the two ends of the water inlet pipe 8 and the water outlet pipe 9 can also be achieved by the flange structure 5. The flange structure 5 is simple to operate and has low requirements on the operator. In addition, the flange structure 5 connection method adopts a bolt fastening method, which can ensure that the connection is tight and leak-free.

[0061] It should be noted that the cold water enters the water inlet pipe 8 through the water pump and other structures, and then enters the high-efficiency tank body 31 through the first connecting pipe 61 and the second connecting pipe 62. The high-efficiency tank body 31 is suitable for exchanging heat with the heat pump unit 11 and cooling the heat pump unit 11. Then the refrigerant water returns to the water outlet pipe 9 through the first connecting pipe 61, and the refrigerant water flows back to the water pump and other structures through the water outlet pipe 9.

[0062] Specifically, a refrigerant inlet pipe 311 and a refrigerant outlet pipe 312 are also provided on the top of the high-efficiency tank body 31. The refrigerant inlet pipe 311 and the second connecting pipe 62 perform heat exchange inside the high-efficiency tank body 31, thereby realizing heat exchange, and the medium after heat exchange flows out along the refrigerant outlet pipe 312.

[0063] Specifically, a branch water pipe is provided between the second connecting pipe 62 and the high-efficiency tank body 31. Specifically, the second connecting pipe 62 is connected to the high-efficiency tank body 31 through six branch water pipes. The six branch water pipes enter the interior of the high-efficiency tank body 31 and exchange heat with the refrigerant inlet pipe 311 in the high-efficiency tank. In this embodiment, by increasing the number of branch water pipes, the heat exchange efficiency between the second connecting pipe 62 and the refrigerant inlet pipe 311 in the high-efficiency tank is increased.

[0064] It should be noted that the four heat pump units 11 correspond to one system respectively. According to the rule from top to bottom and from left to right, the four heat pump units 11 correspond to the first system, the second system, the third system and the fourth system respectively.

[0065]

[0066] Table 1

[0067] Due to the numerous variables in the two experiments, we didn't compare the longitudinal differences between the two data sets. Instead, we compared the same data set. We can see that the variance of the condensing temperatures for the four systems in the prior art is 1.456, which is greater than the 0.0875 for the present invention. A larger variance indicates greater dispersion and unevenness in the data. Preliminary analysis suggests that this is due to excessively long piping from two systems to the high-efficiency tank heat exchanger, leading to heat loss. The present invention, with its centrally located high-efficiency tank heat exchanger, achieves greater stability and consistency in the condensing temperatures across all systems.

[0068] It should be noted that, according to Table 1, compared with the prior art, the length of the first connecting pipe 61 of this solution is the same, and the length of the first connecting pipe 61 is greatly shortened. Because the length of the first connecting pipe 61 is the same, the condensing temperatures of the four systems are basically the same, thereby ensuring the stability and consistency of the performance of each system.

[0069] It should be noted that, compared with the prior art, the high-efficiency heat exchanger 3 in this solution is positioned more centrally.

[0070] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
