Description

Technical Field

[0001] This invention relates to the field of heat exchange technology, specifically to an energy-saving swimming pool heat pump unit and its usage method. Background Technology

[0002] The continuous evaporation of water from the pool surface leads to a continuous increase in relative humidity in the air. This high humidity not only poses a potential threat to buildings but also seriously affects the structure of buildings and the environment. At the same time, the humid and hot air also poses a threat to human health, especially irritating the respiratory tract and potentially causing discomfort or health problems.

[0003] To overcome the above-mentioned defects, existing technology one (Chinese patent with announcement number CN207262596U, announcement date April 20, 2018) discloses a swimming pool heat pump dehumidifier unit, belonging to the field of refrigeration machinery, including an air supply channel and an exhaust channel. The air supply channel is characterized by being composed of a first air valve, an evaporator, an air-cooled condenser, and an air supply fan connected in sequence, with an air supply heat exchanger located at the top of the evaporator; the exhaust channel is composed of a second air valve, an exhaust heat exchanger, and an exhaust fan connected in sequence; the air supply channel and exhaust channel are integrated and installed in parallel within a modular frame; the air supply channel contains a water-cooled dehumidification system, which includes a heating dehumidification loop and a cooling dehumidification loop. Compared to existing swimming pool dehumidifier units, this swimming pool heat pump dehumidifier unit can achieve economical operation of the dehumidifier within the pool according to different seasons and eliminates the need for an outdoor unit system. Existing technology two (publication number...) (Chinese Patent CN106091173A, published on November 9, 2016) A combined dehumidifying and constant-temperature heat pump device for swimming pools includes a swimming pool, a swimming pool, and a dehumidifying heat pump unit. The swimming pool is located inside the swimming pool, and the dehumidifying heat pump unit is located in the swimming pool's machine room. The air circulation pipes of the swimming pool are connected to the dehumidifying heat pump unit, and the water circulation pipes of the swimming pool are also connected to the dehumidifying heat pump unit. The dehumidifying heat pump unit has a built-in installation chamber for replenishing fresh air to the swimming pool. The air inlet and outlet of the built-in installation chamber are connected to the outside air of the swimming pool, respectively. The built-in installation chamber has a first-stage internal heat exchanger and a second-stage internal heat exchanger for heat dissipation or cooling of the flowing air. The first-stage internal heat exchanger and the heat exchanger are connected to the dehumidifying and constant-temperature heat pump unit. Utilizing the built-in installation chamber on the dehumidifying heat pump unit, the device offers advantages such as eliminating the need for re-adjustment during installation, convenient installation, and saving installation space.

[0004] While existing technologies have achieved effective dehumidification through heat pump units, their system structure is highly complex. The air supply and exhaust channels are integrated into one unit, resulting in a complex overall system structure. This not only increases the difficulty of equipment installation, maintenance, and commissioning, but also requires the coordination of multiple heat exchange devices, further increasing the system's complexity and cost.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing energy-saving swimming pool heat pump units and their usage methods. Therefore, we propose that energy-saving swimming pool heat pump units and their usage methods can effectively solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving swimming pool heat pump unit and its usage method, in order to solve the problems mentioned in the background art. Currently, heat pump units on the market achieve effective dehumidification, but their system structure is highly complex. The air supply channel and exhaust channel are integrated into one unit, resulting in a complex system structure. This not only increases the difficulty of equipment installation, maintenance and commissioning, but also requires the cooperation of multiple heat exchange devices, further increasing the complexity and cost of the system.

The lifting plate is connected through the outside of the threaded rod, and a guide rod is provided through the inside of the lifting plate. A contact rod is installed under the lifting plate, and a contact seat is provided directly below the contact rod. The contact seat is located on the placement plate and is electrically connected to the electromagnetic structure. The storage box inside the casing is equipped with a dehumidification component, which includes a dehumidification base installed inside the storage box and a squeezing component installed on the dehumidification base.

[0008] Preferably, the energy-saving component includes a storage box installed on the casing, and an all-glass vacuum heat collection tube is installed inside the storage box. The all-glass vacuum heat collection tube is connected to the delivery pipe at the output end of the first fan, and a protective component is installed on the all-glass vacuum heat collection tube.

[0009] Preferably, the protective component includes a protective baffle on the all-glass vacuum collector tube, the protective baffles are equidistantly arranged, a rotating shaft runs through the inside of the protective baffle, and a rotating gear structure that meshes with the rotating shaft is provided on the outside of the rotating shaft. A solar reflector is installed on the side end of the all-glass vacuum collector tube, and the solar reflector is connected to the inside of the storage box by a bracket and bolt structure.

[0010] Preferably, an auxiliary component is installed on the side of the evaporator. The auxiliary component includes a wind duct installed on the side of the evaporator, an air supply fan is provided inside the wind duct, a support cylinder is installed on one side of the wind duct, and a ring pipe is provided on the outside of the support cylinder.

[0011] Preferably, the input end of the conveying cylinder is connected to the inner cavity of the heat recovery sleeve through a first pipe, and the side end of the heat recovery sleeve is provided with an air delivery groove. The output end of the conveying cylinder is connected to the inner cavity of the support cylinder through a second pipe. The inner cavity of the support cylinder is connected to the inner cavity of the ring pipe. The ring pipe is provided with a through hole near the inner side of the air delivery fan. Both the first pipe and the second pipe are provided with a one-way valve.

[0012] Preferably, the output end of the all-glass vacuum collector tube is connected to a second row of pipes, which is located directly above the dehumidification base. The dehumidification base is equipped with a moisture-absorbing sponge, and a moisture-absorbing box is provided under the dehumidification base. The moisture-absorbing box has an air outlet on its side, and dehumidifying particles are placed inside the moisture-absorbing box. A heating plate is installed at the bottom of the moisture-absorbing box, and the side of the moisture-absorbing box is connected to the evaporator through a conveying pipe.

[0013] Preferably, the extrusion assembly includes an extrusion block mounted on a dehumidification base, with movable blocks mounted at both ends of the extrusion block, a guide rod penetrating through the interior of the movable block, a spring disposed on the outer side of the guide rod, an electromagnetic block mounted on the dehumidification base, the electromagnetic block being electrically connected to a contact seat via a wire, a common magnetic block disposed on the side end of the movable block, and the side end of the dehumidification base being connected to the outside via a water supply pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The energy-saving swimming pool heat pump unit and its usage method feature an evaporator V-shaped fin structure that increases the contact area between air and internally threaded copper tubes, significantly improving the heat exchange rate and reducing heat exchange energy consumption. The overall structure is simple, facilitating installation and maintenance. The all-glass vacuum collector tube absorbs solar energy, improving gas heat absorption efficiency. The specific details are as follows: (1) The V-shaped fins increase the contact area between the air and the copper tube, and the internally threaded copper tube enhances the turbulence of the fluid inside the tube, greatly improving the heat exchange rate. The air supply fan inside the air duct forces the airflow to break the static thermal boundary layer on the surface of the evaporator, thus achieving rapid replacement of hot and cold air.

[0015] (2) The solar reflector concentrates the scattered light into concentrated light, which improves the solar energy absorption rate of the heat collection tube. The heat absorbed by the heat collection tube preheats the airflow in the delivery pipeline, which increases the airflow temperature and reduces the temperature difference loss between the evaporator and the airflow. The compressor does not need to compress the low-temperature airflow significantly, which reduces the overall energy consumption.

[0016] (3) The heat recovery sleeve collects the waste heat of the pipeline between the compressor and the condenser in a closed manner, which not only enhances the heat exchange efficiency of the evaporator, but also improves the defrosting efficiency. The gas flow in the pipeline impacts the rotating wheel, which drives the rotating shaft and bevel gear structure to drive the threaded rod to operate. No additional power input is required, realizing the cascade utilization of energy.

[0017] (4) The moisture-absorbing sponge quickly captures free water vapor in the airflow due to its porous structure. After absorbing moisture, the airflow enters the moisture-absorbing box, where the residual water vapor is deeply adsorbed by the dehumidifying particles. The desorbed water vapor is then transported to the evaporator as a heat exchange medium supplement, thereby improving the heat exchange stability.

[0018] (5) The lifting plate reciprocating motion linkage squeezing mechanism is used. When the lifting plate descends to the preset position, the contact rod triggers the electromagnetic structure, which drives the squeezing block to automatically squeeze the moisture-absorbing sponge to drain water. The squeezed water is discharged from the machine casing through the pipe, realizing the automatic regeneration of the moisture-absorbing sponge and reducing maintenance costs.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: In this example, the heat dissipation airflow around the condenser 8 is guided to the air outlet 11 through the first row of pipes 9, improving the overall heat circulation efficiency. The overall structure is simple and easy to install and maintain. Figures 1-5The technical solution shown includes a casing 1 with an air inlet 2 and an air outlet 11. A first fan 3 is installed inside the casing 1, located below the air inlet 2. The output end of the first fan 3 is connected to an evaporator 5 via a conveying pipe 4. V-shaped fins are located outside the conveying pipe 4 inside the evaporator 5. The conveying pipe 4, which is serpentine in shape inside the evaporator 5, contains internally threaded copper pipes 6. The evaporator 5 is connected to a compressor 7 via the conveying pipe 4. The compressor 7 is connected to a condenser 8 via the conveying pipe 4. The condenser 8 is connected to a first row of pipes 9 via the conveying pipe 4. A second fan 10 is installed on the first row of pipes 9 at the bottom of the air outlet 11. An energy-saving component is installed on the casing 1, including a storage box mounted on the casing 1. The unit is internally equipped with an all-glass vacuum collector tube 25, which is connected to the delivery pipe 4 at the output end of the first fan 3. A protective assembly is installed on the all-glass vacuum collector tube 25, including protective baffles 27. The protective baffles 27 are equidistantly spaced, and a rotating shaft passes through the inside of each baffle. A meshing rotating gear structure 26 is installed on the outside of the rotating shaft. A solar reflector 29 is installed on the side of the all-glass vacuum collector tube 25, and is connected to the storage box via a bracket 28 and bolts. When the first fan 3 is turned on, outside air enters the casing 1 through the air inlet 2 and is delivered to the evaporator 5 through the delivery pipe 4. As the air flows past the V-shaped fins on the outside of the evaporator 5, it interacts with... The internally threaded copper tube 6 inside the conveying pipe 4 performs heat exchange. The V-shaped fin structure increases the contact area between the air and the internally threaded copper tube 6, significantly improving the heat exchange rate and reducing heat exchange energy consumption. A fan 12 is installed on the side of the evaporator 5, and the air-carrying fan 13 inside the fan 12 operates to enhance the heat exchange efficiency of the evaporator 5. The regulated gas enters the compressor 7 through the conveying pipe 4, and after being compressed by the compressor 7, it becomes high-temperature and high-pressure gas. Then, it enters the condenser 8 through the conveying pipe 4. The high-temperature and high-pressure gas releases heat in the condenser 8. The second fan 10 operates, guiding the heat dissipation airflow around the condenser 8 through the first row of pipes 9 to the air outlet 11 for discharge, improving the overall heat circulation efficiency. The overall structure is simple, convenient for installation and maintenance, and a light source is installed on the outside of the casing 1. An intensity sensor, a wind speed sensor, and an ambient temperature sensor are used to monitor solar radiation intensity, ambient wind speed, and ambient temperature in real time to determine whether solar preheating is suitable. The controller processes this information. When it detects that solar energy can be used for auxiliary energy saving, a rotating shaft is driven by a rotating gear structure 26, causing equidistantly spaced protective baffles 27 to open and close. This allows the solar reflector 29, supported by the bracket 28, to reflect scattered solar energy onto the surface of the all-glass vacuum collector tube 25, improving solar energy absorption efficiency. A temperature sensor is also installed on the surface of the all-glass vacuum collector tube 25 to monitor its temperature. Therefore, the protective baffles 27 can automatically close when the temperature of the all-glass vacuum collector tube 25 exceeds a safe threshold.The protective baffle 27 can also automatically close when the wind speed exceeds the limit, thus effectively protecting the all-glass vacuum collector tube 25 and reducing external erosion and loss. The sensors and controllers used are existing technologies and therefore will not be described in detail, nor are they shown in detail in the figure. The solar reflector 29 concentrates the scattered light into focused light, thereby increasing the solar energy absorption rate of the all-glass vacuum collector tube 25. The all-glass vacuum collector tube 25 absorbs solar heat, preheating the airflow in the output pipe 4 of the first fan 3 connected to it, and evaporating the relatively humid airflow. The preheated airflow enters the evaporator 5, improving the gas heat absorption efficiency and reducing the energy consumption of the compressor 7. The pre-evaporation of the airflow removes some moisture, preventing the probability of frost formation on the surface of the evaporator 5.

[0023] Example 2: In this example, the waste heat airflow discharged from the ring pipe 15 is mixed with the airflow around the evaporator 5, which not only enhances the heat exchange efficiency of the evaporator 5, but also improves the defrosting efficiency of the evaporator 5. Specifically, as follows... Figures 5-8As shown, the following are disclosed: The protective assembly includes protective baffles 27 on the all-glass vacuum collector tube 25, with the baffles 27 equidistantly spaced. A rotating shaft passes through the interior of each baffle 27, and a meshing rotating gear structure 26 is provided on the outer side of the rotating shaft. A solar reflector 29 is installed on the side end of the all-glass vacuum collector tube 25, and the solar reflector 29 is connected to the inside of the storage box via a bracket 28 and a bolt structure. An auxiliary assembly is installed on the side end of the evaporator 5, including a fan 12 installed on the side end of the evaporator 5, an air supply fan 13 inside the fan 12, a support cylinder 14 installed on one side of the fan 12, a ring pipe 15 on the outer side of the support cylinder 14, and a heat recovery sleeve 16 fitted outside the conveying pipe 4 between the compressor 7 and the condenser 8. The conveying pipe 4 is internally equipped with a rotating wheel 17. The rotating shaft inside the rotating wheel 17 extends through the side wall of the conveying pipe 4 and is connected to a vertical bevel gear structure 18. A threaded rod 19 is installed below the vertical bevel gear structure 18. The housing 1 is internally equipped with a conveying assembly, which includes a shelf installed inside the housing 1 and a conveying cylinder 21 installed on the shelf. A piston is internally connected to the conveying cylinder 21, and the top of the piston is connected to the bottom of the lifting plate 20. The lifting plate 20 is internally connected to the outside of the threaded rod 19. A guide rod is internally connected to the lifting plate 20. The input end of the conveying cylinder 21 is connected to the inner cavity of the heat recovery sleeve 16 through the first pipe 22. The heat recovery sleeve 16 has an air delivery groove on its side end. The output end of the conveying cylinder 21 is connected to the inner cavity of the support cylinder 14 through the second pipe 23. The inner cavity of the support cylinder 14 is connected to the inner cavity of the ring pipe 15. The ring pipe 15 has a through hole 24 near the inner side of the air supply fan 13. Both the first pipe 22 and the second pipe 23 are equipped with one-way valves. A heat recovery sleeve 16 is sleeved on the outside of the conveying pipe 4 between the compressor 7 and the condenser 8. The conveying pipe 4 dissipates waste heat into the inner cavity of the heat recovery sleeve 16. The rotating wheel 17 inside the conveying pipe 4 rotates under the impact of the gas flow. The rotating wheel 17 drives the rotating shaft that penetrates the side wall of the conveying pipe 4 to rotate. The rotating shaft drives the threaded rod 19 to rotate through the vertical bevel gear structure 18. The mechanism is driven by the kinetic energy of the gas flow in the conveying pipe 4, without the need for additional power input, thus achieving overall energy efficiency. When the threaded rod 19 rotates, it drives the lifting plate 20 that penetrates its outer side to rise along the guide rod. As the piston connected to the bottom of the lifting plate 20 moves downwards, it reciprocates inside the conveying cylinder 21. When the piston rises, the waste heat airflow inside the heat recovery sleeve 16 is drawn into the conveying cylinder 21 through the first pipe 22 with a one-way valve. When the piston falls, the waste heat airflow inside the conveying cylinder 21 is forced into the inner cavity of the support cylinder 14 through the second pipe 23 with a one-way valve. The waste heat airflow then enters the ring pipe 15 through the support cylinder 14 and is discharged through the through hole 24 near the inner side of the air supply fan 13. When the air supply fan 13 inside the air duct 12 is running, it mixes the waste heat airflow discharged from the ring pipe 15 with the airflow around the evaporator 5, which not only enhances the heat exchange efficiency of the evaporator 5 but also improves the defrosting efficiency of the evaporator 5. Moreover, the defrosting process does not require stopping the machine, ensuring continuous operation of the equipment. The overall drive is simple.This facilitates maintenance and reduces the increased failure rate caused by setting up a separate driver.

[0024] Example 3: In this example, the reciprocating motion of the lifting plate 20 is used in conjunction with the squeezing mechanism to achieve automatic water squeezing and regeneration of the moisture-absorbing sponge 32, eliminating the need for manual disassembly and cleaning, thus reducing maintenance costs. Specifically, as follows... Figure 2 and Figures 9-12As shown, the following is disclosed: A dehumidification assembly is installed inside the storage box of the casing 1. The dehumidification assembly includes a dehumidification base 31 installed inside the storage box of the casing 1. The output end of the all-glass vacuum heat collection tube 25 is connected to a second row of pipes 30, which is located directly above the dehumidification base 31. A moisture-absorbing sponge 32 is installed inside the dehumidification base 31. A moisture-absorbing box 33 is installed below the dehumidification base 31. An air outlet 34 is opened on the side of the moisture-absorbing box 33. Dehumidifying particles are placed inside the moisture-absorbing box 33. A heating plate 35 is installed at the bottom of the moisture-absorbing box 33. The side of the moisture-absorbing box 33 is connected to the evaporator 5 through a conveying pipe 4. A contact rod 36 is installed below the lifting plate 20. The contact rod 36 is directly below... A contact seat 37 is provided on the dehumidifying base 31, located on the shelf. The contact seat 37 is electrically connected to the electromagnetic structure. A pressing assembly is installed on the dehumidifying base 31, including a pressing block 43 mounted on the dehumidifying base 31. Moving blocks 40 are installed at both ends of the pressing block 43. A guide rod 41 is connected through the inside of the moving block 40, and a spring 42 is provided on the outside of the guide rod 41. An electromagnetic block 38 is installed on the dehumidifying base 31, and the electromagnetic block 38 is electrically connected to the contact seat 37 through a wire. A common magnetic block 39 is provided on the side of the moving block 40. The side of the dehumidifying base 31 is connected to the outside through a water pipe 44. The second row of pipes 30 at the output end of the all-glass vacuum collector tube 25 is also connected. The preheated airflow is directed to the dehumidification seat 31. Moisture in the airflow is absorbed by the moisture-absorbing sponge 32 inside the dehumidification seat 31, completing dehumidification. The moisture-absorbing sponge 32 has a porous structure and a large moisture absorption capacity, quickly capturing free moisture in the airflow. The dehumidified airflow enters the moisture-absorbing box 33 through the air outlet 34. The dehumidifying particles inside the moisture-absorbing box 33 further absorb residual moisture, forming deep contact with the airflow for precise adsorption of residual moisture. When the lifting plate 20 descends to the preset position, its bottom contact rod 36 contacts the contact seat 37 on the shelf, triggering the electromagnetic structure to be energized. The electromagnetic block 38 generates magnetic force after being energized, interacting with the side of the moving block 40. The ordinary magnetic block 39 attracts each other, driving the moving block 40 to move along the guide rod 41, compressing the spring 42, and simultaneously driving the squeezing block 43 to squeeze the moisture-absorbing sponge 32. The squeezed water is discharged from the casing 1 through the water supply pipe 44. The reciprocating motion of the lifting plate 20 is linked to the squeezing mechanism to realize the automatic water squeezing and regeneration of the moisture-absorbing sponge 32. There is no need for manual disassembly and cleaning, reducing maintenance costs and ensuring the continuous and stable operation of the dehumidification system. The heating plate 35 at the bottom of the moisture-absorbing box 33 can heat and regenerate the dehumidifying particles, extending their service life. The released water vapor is transported to the evaporator 5 through the conveying pipe 4, which facilitates the rapid heat exchange of the evaporator 5 and improves the stability of the heat exchange process.

8. The energy-saving swimming pool heat pump unit according to claim 7 further discloses a method of using the heat pump unit, characterized in that, The specific steps are as follows: S1: Basic heat exchange cycle: Start the first fan (3), the air supply fan (13) and the second fan (10). The outside air enters the evaporator (5) for heat exchange through the air inlet (2) and the conveying pipe (4), and then is compressed by the compressor (7) and released by the condenser (8) to complete the basic heat cycle; S2: Solar-assisted preheating: When solar energy is detected, the rotating gear structure (26) drives the protective baffle (27) to open and close, and the solar reflector (29) concentrates the light to the all-glass vacuum collector tube (25) to preheat and pre-evaporate the airflow in the delivery pipeline (4), thereby reducing the energy consumption of the compressor (7) and the frosting rate of the evaporator (5). S3: Waste heat recovery defrosting: The waste heat in the pipeline (4) between the compressor (7) and the condenser (8) enters the heat recovery sleeve (16), and the gas impacts the rotating wheel (17) to drive the lifting plate (20) to move the piston, and the waste heat gas flow is transported through the ring pipe (15) to the periphery of the evaporator (5) to enhance heat exchange and defrosting without stopping the machine. S4: Automatic regeneration of dehumidification components: The preheated airflow passes through the dehumidification seat (31) and the moisture absorption box (33) for deep dehumidification. The lifting plate (20) descends to trigger the electromagnetic structure. The squeezing block (43) squeezes water out of the moisture-absorbing sponge (32) for regeneration. The heating plate (35) heats and regenerates the dehumidification particles, ensuring the continuous operation of the dehumidification system.
