Description

Technical Field

[0001] This application relates to the technical field of cold energy recovery of air-source heat pump water heaters, and particularly relates to a cold air recovery system for air-source heat pump water heaters. Background Art

[0002] Currently, air-source heat pump water heaters heat water by absorbing heat from the air. During their operation, low-temperature cold air is generated, which is usually directly discharged into the environment, causing energy waste. At the same time, the cooling tower systems widely used in the industrial and building fields rely on the principle of heat dissipation by water evaporation. However, in high-temperature environments (such as summer), the heat dissipation efficiency of cooling towers drops significantly, and it is often necessary to increase the fan power or the circulating water volume to maintain performance, resulting in a sharp increase in energy consumption, an increase in operating costs, and an aggravation of equipment thermal stress losses (such as filler deformation and pipeline aging). In related technologies, air is usually blown by a fan into the cooling tower from the cold air generated by the air-source heat pump water heater as an auxiliary air-cooling source for the cooling tower, so as to improve the heat dissipation efficiency of the cooling tower and reduce energy consumption.

[0003] Regarding the above-mentioned related technologies: When maintenance is required for the fan, the cold air recovery system will temporarily stop working, resulting in the cold air generated by the air-source heat pump water heater not being able to be introduced into the cooling tower. This will cause the cooling tower to lose the source of auxiliary cold air, reduce the heat dissipation efficiency, and thus increase the energy consumption of the cooling tower. At the same time, the operating effect and energy-saving effect of the cold air recovery system will also be temporarily reduced, which will further lead to a reduction in the operating effect of the overall system. Summary of the Invention

[0004] In order to reduce the possibility of the reduction in the operating effect of the overall system, this application provides a cold air recovery system for air-source heat pump water heaters.

[0005] A cold air recovery system for air-source heat pump water heaters provided by this application adopts the following technical solutions: A cold air recovery system for air-source heat pump water heaters includes: A water heater, on which a static pressure box is provided; A air supply mechanism, including a support component and an air supply component. The support component is communicated with the static pressure box, and at least two groups of the air supply components are provided. Multiple groups of the air supply components are respectively communicated with the support component; A cooling tower, which is respectively communicated with multiple groups of the air supply components, and the air supply components are used for supplying air to the cooling tower.

[0006] By adopting the above technical solution, the cold air generated by the hot water unit is evenly distributed through the static pressure box and then guided and distributed to the cooling tower by the air supply mechanism. The design of multiple air supply components can ensure the stable transportation of cold air and at the same time support flexible adjustment of the air volume distribution according to actual needs. This design not only improves the utilization rate of cold air but also effectively enhances the heat dissipation performance of the cooling tower. In a high-temperature environment, the introduction of cold air significantly reduces the inlet water temperature of the cooling tower, thereby reducing the operating time and energy consumption of the cooling tower. In addition, the setting of the static pressure box helps to stabilize the air flow, reduce vibration and noise, and further improves the operating reliability and efficiency of the system. And when one of the air supply components fails, the other air supply components can still continue to work to ensure the continuous supply of cold air to the cooling tower, thus avoiding the problem of reduced cooling efficiency caused by the failure of a single air supply path, and further facilitating reducing the possibility of a decrease in the overall system operating effect.

[0007] Optionally, the air supply component includes a fan and an air supply pipe. The fan is arranged inside the support component. One end of the air supply pipe is communicated with the support component, and the other end of the air supply pipe is communicated with the cooling tower.

[0008] By adopting the above technical solution, the fan is arranged inside the support component, which can effectively extract the cold air generated by the air source heat pump hot water unit from the static pressure box and transport it to the cooling tower. One end of the air supply pipe is communicated with the support component, and the other end is communicated with the cooling tower, ensuring that the cold air can smoothly transfer from the hot water unit to the cooling tower. This design not only improves the efficiency of cold air transportation but also avoids energy loss caused by leakage or excessive resistance during the transmission of cold air. In addition, by reasonably arranging the air supply pipe and the fan, the cold air volume can be flexibly adjusted according to actual needs, thereby improving the heat dissipation effect of the cooling tower and reducing its operating energy consumption. On this basis, the operating stability of the entire system is improved, and at the same time, the service life of the equipment is extended.

[0009] Optionally, the support component includes a support box body and a support seat. The support box body is respectively communicated with the static pressure box and the air supply pipe. The support seat is movably arranged inside the support box body. The fan is arranged on the support seat, and the support seat is used to drive the fan to disengage from the support box body.

[0010] By adopting the above technical solution, the support box body is communicated with the static pressure box and the air supply pipe, so that the cold air can be smoothly introduced from the static pressure box of the hot water unit into the air supply pipe. The support seat is movably arranged in the support box body, and the air supply fan is arranged on the support seat. This design enables the air supply fan to be separated from the support box body along with the movement of the support seat, thus facilitating the maintenance or replacement of the air supply fan. Moreover, when one air supply fan stops working, the remaining air supply fans can continue to operate to avoid the situation that the entire cold air recovery system stops working due to the failure or maintenance of the air supply fan. This design not only improves the maintainability of the system but also ensures that the cooling tower can continuously obtain auxiliary cold air for most of the time, maintaining a high heat dissipation efficiency, thereby reducing the energy consumption of the cooling tower and extending the service life of the equipment.

[0011] Optionally, a plurality of chambers are arranged in the support box body. The plurality of chambers are not communicated with each other, and the plurality of chambers are respectively communicated with the static pressure box. The chambers, the support seat, the air supply fan and the air supply pipe are arranged in one-to-one correspondence.

[0012] By adopting the above technical solution, the support box body is divided into a plurality of non-communicating chambers, and each chamber is respectively communicated with the static pressure box, which can effectively realize the zonal transportation of cold air. This design enables the air supply fans in each chamber to operate independently, accurately controlling the flow rate and direction of cold air according to actual needs. At the same time, the one-to-one correspondence between the chambers, the air supply fans and the air supply pipes avoids the mutual interference of cold air during transportation, improving the utilization rate of cold air. In addition, the multi-chamber structure can also enhance the stability and reliability of the system. Even if a certain chamber or air supply component fails, it will not affect the normal operation of other parts, thus ensuring a continuous and stable cold air supply to the cooling tower and further improving the cooling efficiency.

[0013] Optionally, a through groove is formed in the support box body. The support seat is slidably inserted into the through groove, and a sealing component is arranged between the support seat and the support box body. When the support seat is separated from the support box body, the sealing component seals the support box body.

[0014] By adopting the above technical solution, when the support seat is separated from the support box body, the sealing component can automatically seal the support box body, effectively preventing the leakage of cold air in the box body. This design not only ensures that the cold air can be efficiently transported to the cooling tower but also improves the energy utilization efficiency of the system. At the same time, due to the linkage relationship between the sealing component and the support seat, the entire operation process does not require additional manual intervention, simplifying the maintenance and repair process and improving the reliability and stability of the system. In addition, the connection between the support seat and the support box body is realized by means of sliding insertion, making the structure more compact and reasonable, and facilitating the flexible adjustment of the position and quantity of the air supply components according to actual needs.

[0015] Optionally, the plugging component includes a baffle plate, which is slidably arranged in the support box body and hinged to the support seat. When the support seat disengages from the through groove, the baffle plate can plug the through groove.

[0016] By adopting the above technical solution, when the support seat disengages from the through groove, the support seat can drive the baffle plate to move, so that the baffle plate plugs the through groove, thereby effectively preventing cold air leakage. And at this time, the support seat can rotate relative to the baffle plate to rotate the support seat to a state parallel to the surface of the support box body, without the need for additional fixing devices, thus simplifying the fixing steps of the support seat and facilitating the maintenance of the air blower on the support seat.

[0017] Optionally, an elastic sealing pad is arranged on one side of the baffle plate close to the support seat, and the elastic sealing pad abuts against the support seat.

[0018] By adopting the above technical solution, the setting of the elastic sealing pad can, on the one hand, buffer the mechanical impact between the baffle plate and the support seat, extend the service life of the components, and ensure the stability of the system operation; on the other hand, it can improve the sealing performance when the baffle plate plugs the through groove, thereby effectively preventing cold air leakage.

[0019] Optionally, the plugging component includes a plugging plate and a linkage member. The plugging plate is rotatably connected in the support box body, and the linkage member is respectively connected to the plugging plate and the support seat. When the support seat moves out of the through groove, the linkage member drives the plugging plate to plug the support box body.

[0020] By adopting the above technical solution, when the support seat moves out of the through groove, the support seat can drive the plugging plate to rotate through the linkage member, so that the plugging plate plugs the support box body, thereby effectively preventing cold air leakage. This design not only improves the reliability of the system, but also simplifies the plugging operation, avoids the problem of reduced cooling efficiency caused by cold air leakage, and further improves the energy-saving effect of the entire cold air recovery system.

[0021] Optionally, a receiving groove is formed on the inner wall of the support box body, and the receiving groove is communicated with the through groove. The linkage member includes a rack and a gear. The rack is arranged on the support seat, a rotating shaft is arranged on the plugging plate, the rotating shaft is rotatably connected to the support box body, and one end of the rotating shaft away from the plugging plate is inserted into the receiving groove and coaxially connected to the gear, and the gear meshes with the rack.

[0022] By adopting the above technical solution, a receiving groove is formed on the inner wall of the supporting box body, and the linkage member is designed as a combined structure of a rack and a gear. When the supporting seat moves in the through groove, the rack provided thereon moves accordingly, driving the gear meshing therewith to rotate. The rotation of the gear further drives the rotation of the rotating shaft, thereby realizing the opening or closing action of the sealing plate. This structural design not only ensures the accuracy of the movement of the sealing plate, but also improves the reliability and stability of the system. In addition, due to the meshing transmission of the rack and the gear having a high transmission efficiency and accurate motion control ability, it is possible to effectively reduce the leakage problems that may occur during the sealing process, thereby improving the sealing performance and working efficiency of the entire cold air recovery system.

[0023] Optionally, the sealing plate includes a first plate body and a second plate body. The first plate body is rotatably connected in the supporting box body and connected to the linkage member. The second plate body is slidably connected to the first plate body. A guiding block is provided on the second plate body, and a guiding groove is formed on the inner wall of the supporting box body. The guiding block is slidably inserted into the guiding groove. When the supporting seat drives the first plate body to rotate through the linkage member, the guiding block drives the second plate body to approach or move away from the first plate body.

[0024] By adopting the above technical solution, when the supporting seat moves, the linkage member drives the first plate body to rotate, the first plate body drives the second plate body to rotate, and at the same time, the guiding block slides in the guiding groove, driving the second plate body to approach or move away from the first plate body. This structural design can, on the one hand, ensure that the sealing plate quickly and reliably seals the supporting box body when the supporting seat disengages from the through groove, avoiding air leakage; on the other hand, when the supporting seat is inserted into the through groove, the second plate body moves towards the first plate body, so that the sealing plate no longer seals the supporting box body, and reduces the space occupied by the sealing plate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The cold air recovery system effectively reduces the inlet water temperature of the cooling tower by introducing the cold air generated by the hot water unit into the cooling tower, improves the cooling efficiency, reduces the problem of reduced cooling performance caused by high temperature environment. At the same time, multiple groups of air supply components can take over the work to ensure the continuous supply of cold air to the cooling tower, thereby avoiding the problem of reduced cooling efficiency caused by the failure of a single air supply path, and further facilitating reducing the possibility of the overall system operation effect being reduced; 2. The cooperative design of the support component and multiple groups of air supply components can flexibly distribute the cold air volume according to the actual needs of the cooling tower, avoid the waste of cold air resources, and at the same time reduce the operating energy consumption of the cooling tower fan; 3. Through the mutual cooperation of the supporting seat and the sealing component, it is convenient to take out the air blower from the supporting box body for maintenance or replacement, and at the same time, the sealing component can automatically seal the supporting box body, effectively preventing the leakage of cold air in the supporting box body.

Detailed Description of the Embodiment

[0034] The following further describes the present application in detail with reference to the attached Figure 1-7 drawings.

[0035] An embodiment of the present application discloses a cold air recovery system for an air source heat pump water heater.

[0036] It should be noted that in the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0037] Embodiment 1 Referring to Figure 1 , a cold air recovery system for an air source heat pump water heater includes a water heater 1, a air supply mechanism 2 and a cooling tower 3. Among them, a static pressure box 11 is provided on the water heater 1, and the air supply mechanism 2 is respectively connected to the static pressure box 11 and the cooling tower 3, and the air supply mechanism 2 is used to supply air to the cooling tower 3, which is beneficial to optimize the cold air distribution and improve the cooling efficiency.

[0038] The static pressure box 11 helps to stabilize the air flow, reduce vibration and noise, thereby improving the operation reliability and efficiency of the system. The air supply mechanism 2 includes a support assembly 21 and an air supply assembly 22. Among them, the support assembly 21 is communicated with the static pressure box 11 through a pipeline.

[0039] The air supply assembly 22 includes a fan 221 and an air supply pipe 222. Among them, the fan 221 is installed in the support assembly 21, one end of the air supply pipe 222 is communicated with the support assembly 21, and the other end of the air supply pipe 222 is communicated with the cooling tower 3. Thus, when the fan 221 works, the fan 221 can effectively extract the cold air generated by the water heater 1 from the static pressure box 11 and transport it into the cooling tower 3. In this embodiment, the fan 221 can be a turbine fan or a cross-flow fan, and the air supply pipe 222 can be an oval stainless steel pipe with an inner diameter of 350 mm, which has good corrosion resistance and low air resistance.

[0040] Referring to Figure 1 , a temperature sensor (not shown in the figure) is installed in the cooling tower 3 for real-time monitoring of the outlet water temperature. And an electric air valve (not shown in the figure) is installed on the air supply pipe 222, and the electric air valve is used to adjust the introduction amount of cold air according to the temperature monitored by the temperature sensor.

[0041] It should be noted that the amount of cold air introduced into the cooling tower 3 is automatically adjusted according to parameters such as the outlet water temperature of the cooling tower 3 and the ambient temperature. As for how to adjust specifically, and the specific structures of the water heater 1 and the cooling tower 3, they belong to conventional technical means for those skilled in the art, so they will not be elaborated too much in the embodiments of this application.

[0042] In the embodiments of the present application, the cold air generated by the hot water unit 1 is conveyed into the cooling tower 3 to reduce the inlet water temperature of the cooling tower 3, improve the heat dissipation effect of the cooling tower 3, thereby effectively reducing the operating time and energy consumption of the cooling tower 3, improving the utilization rate of cold air, and extending the service life of the equipment.

[0043] Embodiment 2 Referring to Figure 2 and Figure 3 , the difference between this embodiment and Embodiment 1 is that there are two sets of air supply assemblies 22, and the support assembly 21 includes a support box body 211 and a support seat 212.

[0044] Referring to Figure 2 and Figure 3 , the air supply pipe 222 is communicated with the support box body 211. A plurality of chambers 2111 are arranged in the support box body 211. The plurality of chambers 2111 are not communicated with each other, and the plurality of chambers 2111 are respectively communicated with the static pressure box 11, so that the cold air in the static pressure box 11 can flow into different chambers 2111 respectively, and the cold air in different chambers 2111 cannot flow to each other.

[0045] In this embodiment, the number of chambers 2111 is equal to the number of air supply assemblies 22, and the chambers 2111, the support seats 212, the air supply fans 221 and the air supply pipes 222 are arranged in one-to-one correspondence. This design can realize the zonal control of cold air, so that the air supply fans 221 in each chamber 2111 can operate independently, so as to accurately control the flow rate and direction of cold air according to actual needs.

[0046] When it is necessary to maintain or replace a single air supply fan 221, the other air supply fan 221 can still work normally, so as to ensure that the cooling tower 3 obtains a continuous and stable cold air supply, and further avoid the problem of reduced cooling efficiency caused by the failure of a single air supply path, and reduce the possibility of reducing the operating effect of the overall system.

[0047] In other embodiments, the number of air supply assemblies 22 can also be set to three groups, four groups, etc.

[0048] Referring to Figure 3 , a through groove 2112 is opened at the top of the support box body 211, and the support seat 212 is slidably inserted into the through groove 2112 and fits with the inner wall of the through groove 2112, so that the support seat 212 can slide stably in the through groove 2112. The air supply fan 221 is installed on the support seat 212, so that the support seat 212 can drive the air supply fan 221 away from the support box body 211 to facilitate the disassembly, assembly and maintenance of the air supply fan 221.

[0049] Referring to Figure 3 and Figure 4, a blocking component 23 is arranged between the support base 212 and the support box body 211. The blocking component 23 includes a baffle 231, a blocking plate 232 and a linkage 233. Among them, the baffle 231 is slidably arranged in the support box body 211 and is hinged to the support base 212. When the support base 212 disengages from the through groove 2112, the baffle 231 can block the through groove 2112, thereby effectively preventing cold air leakage.

[0050] When the support base 212 completely disengages from the through groove 2112, the support base 212 can rotate relative to the baffle 231 to rotate the support base 212 to a horizontal state. At this time, the support base 212 is supported by the support box body 211, and the support base 212 no longer exerts pressure on the baffle 231. Therefore, without additional fixing devices, the positions of the support base 212 and the baffle 231 can be kept fixed. On the one hand, this is beneficial to reducing production costs, and on the other hand, it simplifies the operation steps and facilitates the maintenance of the air blower 221 on the support base 212.

[0051] Refer to Figure 3 , an elastic sealing pad 2311 is arranged on one side of the baffle 231 close to the support base 212. The elastic sealing pad 2311 abuts against the support base 212. Thus, on the one hand, it can buffer the mechanical impact between the baffle 231 and the support base 212, extend the service life of the components, and ensure the stability of the system operation; on the other hand, when the baffle 231 blocks the through groove 2112, the elastic sealing pad 2311 can fill the gap between the baffle 231 and the inner wall of the through groove 2112 to improve the sealing performance and further prevent cold air leakage.

[0052] Refer to Figure 4 and Figure 5 , the blocking plate 232 is rotatably connected in the support box body 211. The linkage 233 is respectively connected to the blocking plate 232 and the support base 212. When the support base 212 moves out of the through groove 2112, the support base 212 can drive the blocking plate 232 to block the support box body 211 through the linkage 233.

[0053] Refer to Figure 6 and Figure 7 , a receiving groove 2113 is formed on the inner wall of the support box body 211. The receiving groove 2113 communicates with the through groove 2112. The blocking plate 232 includes a first plate body 2321 and a second plate body 2322. Among them, a rotating shaft 2323 is fixedly connected to the first plate body 2321. The rotating shaft 2323 is rotatably connected to the support box body 211, and one end of the rotating shaft 2323 away from the first plate body 2321 is inserted into the receiving groove 2113.

[0054] It should be noted that in this embodiment, a mechanical seal structure is provided at the connection between the rotating shaft 2323 and the support box body 211 to avoid air leakage. As for the specific seal structure adopted, it belongs to conventional technical means for those skilled in the art. Therefore, it will not be elaborated too much in the embodiments of this application.

[0055] Referring to Figure 4 and Figure 6 , the second plate body 2322 is slidably connected to the first plate body 2321, and a guide block 2324 is fixedly connected to the second plate body 2322. In this embodiment, the cross-section of the guide block 2324 is circular. A guide groove 2114 is formed on the inner wall of the support box body 211. The guide groove 2114 is arc-shaped. The guide block 2324 is slidably inserted into the guide groove 2114. When the first plate body 2321 drives the second plate body 2322 to rotate, the second plate body 2322 can drive the guide block 2324 to move in the guide groove 2114. At the same time, the inner wall of the guide groove 2114 exerts a force on the guide block 2324, so that the guide block 2324 drives the second plate body 2322 to approach or move away from the first plate body 2321.

[0056] Referring to Figure 4 and Figure 7 , the linkage member 233 includes a rack 2331 and a gear 2332. Among them, the rack 2331 is fixedly connected to the support base 212. The gear 2332 is located in the receiving groove 2113 and is coaxially fixedly connected to the rotating shaft 2323. The gear 2332 meshes with the rack 2331. Thus, when the support base 212 moves in the through groove 2112, the rack 2331 provided thereon moves accordingly, driving the meshing gear 2332 to rotate. The rotation of the gear 2332 further drives the rotating shaft 2323 to rotate, thereby realizing the opening or closing action of the blocking plate 232.

[0057] In this embodiment, a sealing gasket is filled between the support base 212 and the inner wall of the through groove 2112, and a sealing gasket adapted to the blocking plate 232 is provided in the support box body 211, which is beneficial to avoiding cold air leakage.

[0058] The implementation principle of Embodiment 2 is as follows: When it is necessary to maintain a single air blower 221, first move the support base 212 until it completely disengages from the through slot 2112, and then rotate the support base 212 to a horizontal state to facilitate the maintenance of the air blower 221. At the same time, the support base 212 drives the baffle 231 and the rack 2331 to move, so that the baffle 231 blocks the through slot 2112, and the rack 2331 drives the gear 2332 to rotate. The gear 2332 drives the first plate body 2321 and the second plate body 2322 to rotate to a vertical state through the rotating shaft 2323. During this process, the guiding block 2324 drives the second plate body 2322 to move away from the first plate body 2321, so that the second plate body 2322 and the first plate body 2321 block the corresponding chamber 2111, thereby preventing cold air from leaking.

[0059] When the maintenance of the air blower 221 is completed, rotate the support base 212 to a vertical state, and then move the support base 212 into the chamber 2111. The support base 212 drives the baffle 231 and the rack 2331 to move into the chamber 2111. At the same time, the rack 2331 drives the first plate body 2321 and the second plate body 2322 to rotate to a horizontal state through the gear 2332 and the rotating shaft 2323. During this process, the guiding block 2324 drives the second plate body 2322 to move closer to the first plate body 2321, so that the second plate body 2322 and the first plate body 2321 no longer block the chamber 2111, facilitating the passage of cold air.

[0060] In this embodiment, when the first plate body 2321 and the second plate body 2322 are in a horizontal state, the space required by the first plate body 2321 and the second plate body 2322 is reduced, which is beneficial to reducing the volume of the support box body 211, and further beneficial to reducing the production cost.

[0061] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
