Description

Technical Field

[0001] The present invention relates to the technical field of ground source heat pump air conditioners, and in particular to a waste heat recovery type ground source heat pump air conditioner unit. Background Art

[0002] Geothermal heat pump air conditioners utilize the earth's surface temperature for heat exchange, achieving warmth in winter and cooling in summer. Because the ground is a constant temperature layer at a certain depth below the surface—for example, the temperature within 150 meters of the surface remains stable at around 15 degrees Celsius year-round—the ground's surface temperature can be used for cooling in summer and heating in winter. Existing technology utilizes this natural characteristic to achieve heat exchange using geothermal heat pump air conditioners. However, geothermal heat pumps typically use water as the heat exchange medium. Due to their stable operating conditions, geothermal heat pumps offer simple, reliable operation and low maintenance costs. They also have a high degree of automatic control and a long service life of up to 15 years.

[0003] The prior art proposes a ground source heat pump air conditioning unit, application number CN202210017729.4, including a heat exchanger, the heat exchanger including a shell, a heat exchange tube and a cleaning unit, the heat exchange tube being arranged inside the shell, and the number is more than two, and the end of the heat exchange tube connected to the water inlet pipe is provided with a cleaning unit; the cleaning unit includes a rotating shaft, a cleaning plug and a steel coil, the rotating shaft is rotatably connected to the inner wall of the heat exchange tube, and disc springs are fixed at the connection points at both ends, one end of the steel coil is fixed to the center of the rotating shaft, the end of the steel coil away from the rotating shaft is fixed to the cleaning plug, and the length of the steel coil is consistent with the height of the shell; brushes are fixed on both sides of the cleaning plug; the present invention cooperates with the cleaning plug and the steel coil, so that the heat exchange tube in the heat exchanger can be automatically cleaned each time it is used, thereby solving the problem of troublesome cleaning inside the tube, and thereby increasing the service life of the ground source heat pump air conditioning unit.

[0004] However, the existing technology, especially this solution, still has the following problems: in the heat exchanger of the ground source heat pump air-conditioning unit, the single cleaning movement leads to residual dead corners and cannot completely cover all the positions to be cleaned in the heat exchange tube. In addition, its cleaning components permanently occupy the flow channel, affecting the internal water flow velocity.

DETAILED DESCRIPTION

[0034] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0035] Embodiment: The invention provides Figures 1 to 9 As shown, a waste heat recovery ground source heat pump air conditioning unit includes:

[0036] Heat exchanger 12, which circulates and heats user water based on geothermal energy. A rotating wheel 21 driven by running water is installed at the water inlet 18 of the heat exchanger 12;

[0037] The heat exchanger 12 is provided with multiple groups of heat exchange tubes 111 inside, and the heat exchange tubes 111 are provided with rotating cleaning parts 25 inside. The rotating cleaning parts 25 can rotate and reciprocate inside the heat exchange tubes 111 to clean the inner wall; the heat exchange tubes 111 can be moved and stored in the cavities at both ends of the heat exchange tubes 111 inside the heat exchanger 12.

[0038] Working principle:

[0039] The water flow is converted from a self-driving force. Water from the water inlet 18 strikes the rotating wheel 21, converting the fluid's kinetic energy into mechanical energy, which drives the rotating cleaning element 25. The dynamic cleaning and covering mechanism allows the rotating cleaning element 25 to simultaneously rotate and move axially within the heat exchange tube 111, following a spiral path to cover the tube wall and remove tiny scale deposits. This zero-interference heat exchange mode allows the cleaning element to completely withdraw from the heat exchange tube 111 into the cavities at both ends, eliminating the flow resistance of traditional fixed cleaning structures.

[0040] Energy recycling utilizes incoming water flow to drive cleaning, achieving zero additional energy consumption for scale prevention, and is more energy-efficient than pure electric cleaning. Self-cleaning eliminates dead angles, utilizing a combination of rotation and reciprocating motion, reducing thermal resistance, and achieving full tube wall coverage. Heat exchange efficiency is guaranteed without loss, with a built-in cleaning element design that avoids permanent flow resistance loss and maintains the designed flow rate and heat transfer coefficient, unlike traditional cleaning structures that result in flow rate attenuation. The hydraulic self-drive and retractable cleaning structure ensure zero-scale operation while eliminating the negative impact of cleaning components on heat exchange efficiency.

[0041] Specifically, such as Figures 1 to 3 As shown, the heat exchanger 12 and the water tank 13 are installed on the base 11, and a return pipe 17 is provided at the inlet of the water tank 13. The water tank 13 is connected to the water inlet 18 of the heat exchanger 12, and the water outlet 19 of the heat exchanger 12 is connected to the water distribution pipe 15. Several groups of water outlet pipes 16 are provided on the water distribution pipe 15. A supply pump 14 is provided at the connection position of the water distribution pipe 15 and the water outlet pipe 16. The water outlet pipe 16 is used to connect to the user end to supply heat energy to the user. The water body after supplying heat energy completes the circulation process through the return pipe 17. Other related control contents are well known to those skilled in the art and will not be repeated here.

[0042] A plurality of passive rotating rods 210 are installed in the heat exchanger 12 through the heat exchange tube 111 , and the rotating cleaning member 25 rotates and reciprocates in the heat exchange tube 111 via the passive rotating rods 210 .

[0043] The rotating wheel 21 drives the multiple groups of passive rotating rods 210 simultaneously through the driving structure, and the rotating cleaning member 25 rotates following the passive rotating rods 210, thereby realizing the rotation of the rotating cleaning member 25 inside the heat exchange tube 111;

[0044] The rotating cleaning member 25 is slidably mounted on the passive rotating rod 210. Pull ropes 211 are provided at both ends of the heat exchange tube 111. Two sets of pull ropes 211 are respectively connected to the two ends of the rotating cleaning member 25. The two sets of pull ropes 211 are used to pull the rotating cleaning member 25 to achieve reciprocating cleaning.

[0045] The multiple groups of heat exchange tubes 111 inside the heat exchanger 12 are distributed in a circular array, and the passive rotating rods 210 are located at the axial position inside the heat exchange tubes 111. The passive rotating rods 210 of the multiple groups of heat exchange tubes 111 are synchronously driven to rotate by the driving structure. The axial position of the rotating wheel 21 is connected to the active rotating rod 27, and the active rotating rod 27 drives the multiple groups of passive rotating rods 210 to rotate through the driving structure.

[0046] The driving structure includes a driving wheel 22 and a driving wheel 23. The driving wheel 22 is installed on the active rotating rod 27, and the driving wheel 23 is installed on the passive rotating rod 210. The multiple groups of driving wheels 23 are synchronously driven and transmitted through the transmission belt 29. The driving wheel 22 drives the driving wheel 23 through the transmission belt 29 to realize the simultaneous driving of the multiple groups of passive rotating rods 210 by the rotating wheel 21.

[0047] It also includes a driving wheel 22 installed on the active rotating rod 27. The driving wheel 22 is located at the other end of the active rotating rod 27 and is also provided with a driving motor. The driving motor is used to drive the driving wheel 22 and the rotating wheel 21 to rotate, so that the driving wheel 22 drives and rotates multiple groups of passive rotating rods 210, and at the same time drives and rotates the rotating wheel 21 to improve the water inlet effect of the water inlet 18.

[0048] like Figure 6 As shown, a driving clutch 215 is provided between the active rotating rod 27 and the driving wheel 22 and between the driving motor and the driving wheel 22. The driving clutch 215 can realize the selection and switching of the two driving modes of the active rotating rod 27 and the driving motor.

[0049] Hoists 24 are installed at both ends of the heat exchanger 12 . The hoists 24 drive the rotating cleaning member 25 to move back and forth via two sets of pull ropes 211 .

[0050] like Figure 4 As shown, a bracket 110 is installed on the outside of the heat exchanger 12, and the bracket 110 is used to install structures such as the driving wheel 22, the driving wheel 23 and the winch 24;

[0051] Furthermore, regarding the cleaning control method of this application, first of all, the ground source heat pump air-conditioning unit of this scheme has two states, a storage state and a cleaning state; in the storage state, the rotating cleaning member 25 is stored in the cavities at both ends of the heat exchanger 12. At this time, the rotating cleaning member 25 is not inside the heat exchange tube 111, and will not affect the water flow rate inside the heat exchange tube 111; in the cleaning state, the rotating cleaning member 25 rotates under the drive of the passive rotating rod 210, and at the same time, under the control of the pull rope 211, the rotating cleaning member 25 reciprocates inside the heat exchange tube 111. Here, the rotating cleaning member 25 rotates and reciprocates to completely clean the inside of the heat exchange tube 111. The driving essence of the passive rotating rod 210 and the pull rope 211 here is to control the output mode of its driving source. The scheme also includes a controller for controlling the driving source. The content of the controller here is common knowledge and will not be elaborated on.

[0052] The rotating cleaning member 25 is provided with rotating members 212 at both ends thereof, and the rotating members 212 can rotate at both ends of the rotating cleaning member 25. Two sets of pull ropes 211 are connected to both ends of the rotating cleaning member 25 through the rotating members 212, that is, the pull ropes 211 are connected to the rotating members 212, and the rotating members 212 are rotatably installed at one end of the rotating cleaning member 25, so that the pulling movement of the rotating cleaning member 25 by the pull ropes 211 will not interfere with the rotation of the rotating cleaning member 25.

[0053] The rotating cleaning member 25 is configured as a spiral structure, a moving groove 213 is provided on the passive rotating rod 210, a sliding hole is provided at the axial position of the rotating cleaning member 25 and is slidably mounted on the passive rotating rod 210 through the sliding hole, a positioning block 214 is connected to the sliding hole of the rotating cleaning member 25, and the positioning block 214 is slidably installed in the moving groove 213, this configuration enables the passive rotating rod 210 to drive the rotating cleaning member 25 to rotate, and at the same time the rotating cleaning member 25 can slide and move on the passive rotating rod 210.

[0054] A partition 112 is provided inside the cavity of the heat exchanger 12 near the water inlet 18. The partition 112 divides the cavity into two cavities. The water inlet 18 is provided on one of the cavities, and the water outlet 19 is provided on the other cavity.

[0055] The heat source circulation cavity of the heat exchanger 12 is provided with a heat source inlet and a heat source outlet. The direction of the heat source flow inside the heat exchanger 12 is opposite to the direction of the water flow. Under such a water flow direction setting, Figure 4 As shown, from the flow direction of the user's water, the temperature of the water gradually increases, and from the flow direction of the heat source, the heat source first contacts the water with a higher temperature, and then contacts the water with a lower temperature when the temperature of the heat source decreases, thereby achieving a temperature gradient increase and improving the heat utilization efficiency of the heat source by the heat exchanger 12.

[0056] Optional, such as Figure 6 As shown, support plates 26 and seals 216 are provided at both ends of the interior of the heat exchanger 12. The passive rotating rod 210 rotates through the support plate 26 and can be used to position multiple groups of passive rotating rods 210. The passive rotating rod 210 passes through both ends of the heat exchanger 12, and the seals 216 are used to seal the position where the passive rotating rod 210 passes through. More specifically, a disassembly seat 28 is provided inside the water inlet 18 of the heat exchanger 12, and the rotating wheel 21 can be detachably installed inside the water inlet 18 through the disassembly seat 28.

[0057] The present invention also has the following comprehensive effects:

[0058] The water-driven cleaning system features a rotating wheel 21 linkage: Water flow from the water inlet 18 drives the rotating wheel 21, which in turn rotates all passive rotating rods 210 through the active rotating rod 27 and transmission belt 29, causing the rotating cleaning element 25 within the heat exchange tube 111 to rotate. A reciprocating cleaning mechanism: The winch 24 pulls the rotating cleaning element 25 along the axial direction of the passive rotating rod 210 via pull ropes 211 at both ends, achieving a combined rotational and reciprocating motion. The system features intelligent dual-state switching. In the stowed state, the rotating cleaning element 25 is completely withdrawn from the heat exchange tube 111 into the cavities at both ends, creating zero water flow resistance and ensuring efficient heat transfer. In the cleaning state, the rotating cleaning element 25 performs a spiral scraping operation within the heat exchange tube 111, removing scale. The countercurrent heat exchange layout optimizes thermal efficiency: user water flows in opposite directions from the geothermal source, concentrating heat exchange in high-temperature areas and improving heat recovery. The annular array of heat exchange tubes 111 evenly distributes the heat exchange surface, preventing localized overheating or overcooling.

[0059] Zero-energy self-cleaning: water flow drives the rotating wheel 21, eliminating the need for an external power source for basic cleaning and reducing operation and maintenance costs. The drive clutch 215 supports motor assistance to cope with low-flow conditions, such as at night. Non-destructive deep cleaning: spiral cleaning elements + axial movement cover the pipe wall, and the scale inhibition rate is lower than that of traditional fixed brush residues. The rotating element 212 decouples rotation or movement to prevent the pull rope 211 from entanglement and breakage. Continuous and efficient heat exchange: the cleaning element storage design releases the flow area of ​​the heat exchange tube 111 and increases the flow rate. Countercurrent gradient heat exchange increases the outlet water temperature. A breakthrough in maintenance convenience: the detachable rotating wheel 21 design, the external winch 24 for quick replacement, and the pull rope 211 can be replaced without opening the tank. Technology generation advantage: Traditional heat pumps: shutdown to disassemble and clean the heat exchange tube 111, resulting in a large number of lost work hours each year; this solution uses online self-cleaning and countercurrent efficiency enhancement to improve overall energy efficiency throughout the year.

[0060] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
