Description

Technical Field

[0001] The present invention relates to the technical field of air source heat pumps, and specifically to a system for improving the efficiency of air source heat pumps by utilizing photovoltaic energy. Background Art

[0002] Under the general trend of global energy transformation and energy conservation and emission reduction, air source heat pumps, as a kind of efficient renewable energy utilization equipment, are widely used in fields such as building heating, cooling, and hot water supply. Based on the reverse Carnot cycle principle, air source heat pumps transfer heat from a low-temperature heat source (air) to a high-temperature heat source by consuming a small amount of electric energy to drive a compressor, and have significant advantages of environmental protection and energy conservation. However, their operating efficiency is greatly affected by the ambient temperature. In a low-temperature environment, the heating capacity and coefficient of performance of the heat pump will decrease significantly, resulting in increased energy consumption and operating costs. In addition, there is still room for improvement in the energy conversion efficiency of the air source heat pump system itself. The traditional power supply method mostly relies on the conventional power grid and cannot make full use of renewable energy.

[0003] At present, the technical means to improve the efficiency of air source heat pumps in the market mainly include optimizing the design of core components such as compressors and heat exchangers of heat pump units, adopting intelligent control systems to adjust operating parameters, and combining energy storage devices to smooth load fluctuations. In terms of mechanical structure, by improving the compression ratio and volumetric efficiency of the compressor, increasing the heat transfer area of the heat exchanger, optimizing the arrangement of heat transfer tubes, etc., the heat transfer efficiency is improved; in terms of control technology, sensors are used to monitor parameters such as ambient temperature and load demand in real time, and the operating frequency and power of the heat pump are automatically adjusted. However, these technologies mostly focus on the optimization of a single link and lack systematic collaborative design.

[0004] In actual application scenarios, such as winter heating in cold regions, the traditional air source heat pump has insufficient heating capacity due to the low-temperature environment. Frequent start-stop not only reduces the service life of the equipment, but also greatly increases energy consumption. In addition, the conventional power grid power supply mode cannot effectively utilize clean energy, resulting in energy waste and increased carbon emissions. And in the existing photovoltaic-air source heat pump coupling systems, there are generally problems such as insufficient utilization of photovoltaic energy, lack of coordinated cooperation between the heat pump and photovoltaic modules, and inconvenient system maintenance. For example, the power generation efficiency of photovoltaic panels decreases at high temperatures, and components such as the filter screen and heat exchanger of the air source heat pump are prone to dust accumulation and blockage, affecting air circulation and heat exchange effects.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to the attached Figure 1 - attached Figure 8, an embodiment of the present invention provides a system for improving the efficiency of an air source heat pump using photovoltaic energy, including an air source heat pump unit 1 and a photovoltaic power generation panel 2. The photovoltaic power generation panel 2 is located on the top of the air source heat pump unit 1, and is characterized in that: a cooling mechanism 3 is provided on the top of the air source heat pump unit 1, an assembly mechanism 4 is provided at the bottom of the cooling mechanism 3, a power supply component 5 is provided at the bottom of the photovoltaic power generation panel 2, an outer network cover 8 is detachably connected to the outside of the air source heat pump unit 1, a cleaning mechanism 6 is provided on the outside of the air source heat pump unit 1, and a dust removal mechanism 7 is provided on the outside of the outer network cover 8. The cooling mechanism 3 includes a water injection box 301, the water injection box 301 is fixedly connected to the top of the air source heat pump unit 1, a first condensation pipe 303 is fixedly connected to the outside of the water injection box 301, the first condensation pipe 303 is located inside the air source heat pump unit 1, and a water injection port 302 is opened on the outside of the water injection box 301. A refrigeration device 304 is fixedly connected to the bottom of the photovoltaic power generation panel 2, a circuit board housing 305 is fixedly connected to the bottom of the photovoltaic power generation panel 2, a second condensation pipe 306 is fixedly connected to the outside of the refrigeration device 304, and the second condensation pipe 306 is located at the bottom of the circuit board housing 305. When the system is started, the photovoltaic power generation panel 2 converts solar energy into direct current through the photovoltaic effect of semiconductor materials, and a part of it directly supplies the components such as the compressor and fan of the air source heat pump unit 1 to operate. Based on the reverse Carnot cycle principle, in the heating mode, the low-temperature and low-pressure liquid refrigerant absorbs the heat of the outside air and vaporizes in the evaporator, is compressed into a high-temperature and high-pressure gaseous refrigerant by the compressor, releases heat in the condenser to heat the circulating water, condenses into a liquid state by itself, and then throttles and depressurizes through the expansion valve and re-enters the evaporator for circulation; the refrigeration mode is the opposite, realizing the transfer of heat from the water side to the air side.

[0022] The refrigeration device 304 adopts a refrigeration cycle similar to that of a compressor. Taking refrigerants such as Freon as an example: the low-pressure gaseous refrigerant is sucked into the compressor and compressed into a high-temperature and high-pressure gas, flows through the second condensation pipe 306 to dissipate heat and condenses into a high-pressure liquid, enters the evaporator after being depressurized and cooled by a throttling device, and absorbs the surrounding heat to vaporize to achieve refrigeration. During this process, the refrigeration device 304 cools the water introduced into the water injection box 301 through the water injection port 302, and the low-temperature water absorbs the heat of the heating elements inside the air source heat pump unit 1 through the first condensation pipe 303, reducing the temperature of the elements and reducing the performance loss caused by overheating; at the same time, the second condensation pipe 306 reduces the temperature of the photovoltaic power generation panel 2 through heat conduction, thereby improving the overall system efficiency.

[0023] The assembly mechanism 4 includes an assembly cover 401 which is arranged at the bottom of the circuit board housing 305. Two notch grooves 402 are formed on one side of the assembly cover 401. The outer side of the second condenser tube 306 is fitted with the inner sides of the two notch grooves 402. Fixed plates 403 are fixedly connected to both outer sides of the assembly cover 401. Prismatic table-shaped clamping blocks 404 are fixedly connected to the outer sides of the fixed plates 403. Card slots 405 are formed on both outer sides of the circuit board housing 305. The outer sides of the fixed plates 403 are slidably connected to the outer side of the circuit board housing 305. The outer sides of the prismatic table-shaped clamping blocks 404 are engaged inside the card slots 405. The inclined surface design of the prismatic table-shaped clamping blocks 404 enables the assembly cover 401 to be automatically clamped when inserted. The width of the card slot 405 is slightly larger than the bottom width of the prismatic table-shaped clamping block 404, forming an interference fit. During maintenance, applying a pulling force in the horizontal direction can overcome the friction force to make the prismatic table-shaped clamping block 404 disengage from the card slot 405, realizing the quick disassembly and maintenance of the second condenser tube 306 and avoiding the cumbersome process of traditional bolt connection that requires tools for disassembly.

[0024] The power supply assembly 5 includes a power storage device 501. Wires 502 and 503 are fixedly connected to the outer side of the power storage device 501. One end of the wire 502 is electrically connected to the refrigeration device 304. The power storage device 501 is electrically connected to the photovoltaic power generation panel 2. The power storage device 501 adopts lead-acid battery or lithium battery energy storage technology. Taking the lithium battery as an example, during charging, lithium ions are removed from the positive electrode material and embedded in the negative electrode material to store electrical energy; during discharging, lithium ions are removed from the negative electrode and return to the positive electrode, and electrons flow through the external circuit to the positive electrode to form an electric current. When the photovoltaic power generation is excessive, the excess electrical energy is stored in the power storage device 501 through the charging circuit; when the light is insufficient or during night operation, the power storage device 501 converts direct current into alternating current through a DC-AC inverter, and supplies power to the refrigeration device 304 through the wire 502 to maintain the cooling function, and supplies power to the motor 608 through the wire 503 to realize active dust cleaning.

[0025] The cleaning mechanism 6 includes two sets of fixed blocks 601, with two fixed blocks 601 in each set. A reciprocating lead screw 602 is rotatably connected inside one set of fixed blocks 601. A fan blade 603 is fixedly connected to the bottom end of the reciprocating lead screw 602. A threaded block 605 is threadedly connected to the outside of the reciprocating lead screw 602. A guide rod 607 is fixedly connected inside the other set of fixed blocks 601. A slider 606 is slidably connected to the outside of the guide rod 607. The adjacent sides of the slider 606 and the threaded block 605 are fixedly connected with a brush plate 604. The outside of the brush plate 604 is in contact with the outside of the outer mesh cover 8. A motor 608 is installed on the outside of the air source heat pump unit 1. The output end of the motor 608 is fixedly connected to the top of the reciprocating lead screw 602. The motor 608 is electrically connected to one end of the second wire 503. When the external wind drives the fan blade 603 to rotate, the fan blade 603 drives the reciprocating lead screw 602 to rotate. The threaded block 605 moves in the spiral groove of the lead screw. The guide rod 607 and the slider 606 ensure that the brush plate 604 moves in a straight line. When the wind direction changes and causes the fan blade 603 to reverse, the threaded block 605 will automatically move in the reverse direction to achieve the reciprocating cleaning of the brush plate 604. The accumulation of dust on the surface of the outer mesh cover 8 will cause an increase in the air flow resistance. Regular cleaning by the brush plate 604 can restore the air flow efficiency and reduce the energy consumption of the fan. When the wind force is insufficient, the motor 608 is powered by the energy storage device 501 to drive the reciprocating lead screw 602 to achieve active dust cleaning.

[0026] The dust removal mechanism 7 includes an air cylinder 701 and a cam 705. The air cylinder 701 is fixedly connected to the outside of the outer mesh cover 8. A sliding rod 702 is slidably connected to the through hole at one end of the air cylinder 701. One end of the sliding rod 702 is fixedly connected to a piston 703. The outside of the piston 703 is slidably connected to the inner wall of the air cylinder 701. The cam 705 is fixedly connected to the output end of the motor 608. The other end of the sliding rod 702 is in contact with the outside of the cam 705. A spring 704 is sleeved outside the sliding rod 702. One end of the spring 704 is fixedly connected to one end of the air cylinder 701, and the other end of the spring 704 is fixedly connected to the other end of the sliding rod 702. An air inlet 706 is opened at the other end of the air cylinder 701. An air outlet pipe 707 is fixedly connected to the outside of the air cylinder 701. One end of the air outlet pipe 707 is fixedly connected to a jet frame 708. The jet frame 708 is fixedly connected to the outside of the outer mesh cover 8. One-way valves are provided inside both the air inlet 706 and the air outlet pipe 707. When the motor 608 drives the cam 705 to rotate, the eccentric contour of the cam 705 pushes the sliding rod 702 to compress the spring 704, and the piston 703 moves forward in the air cylinder 701. The air in the air cylinder 701 is compressed, and the one-way valve at the air outlet opens, and the air flow enters the jet frame 708 through the air outlet pipe 707. When the cam 705 continues to rotate, the spring 704 rebounds to drive the piston 703 to move backward, a negative pressure is formed in the air cylinder 701, and the one-way valve at the air inlet 706 opens to suck in outside air. The air outlet of the jet frame 708 is designed in a slit shape, which can accelerate the air flow and effectively disperse the dust raised when the brush plate 604 is cleaning, avoiding secondary adsorption.

[0027] Specifically, first of all, through the photovoltaic effect of semiconductor materials, the photovoltaic power generation panel 2 directly converts the absorbed solar energy into direct current to supply power to the core components such as the compressor and the fan of the air source heat pump unit 1. When the light is sufficient, in addition to meeting the real-time operation requirements of the air source heat pump unit 1, the remaining power generated by the photovoltaic power generation panel 2 will be stored in the energy storage device 501 in the form of chemical energy through the intelligent charging management system. Taking a common lithium battery as an example, during charging, lithium ions are removed from the positive electrode material and embedded in the negative electrode material to achieve efficient storage of electrical energy and avoid energy waste.

[0028] When the photovoltaic power generation panel 2 and the air source heat pump unit 1 are running synchronously, the refrigeration device 304 starts the refrigeration process. The compressor inside it compresses the low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous state, and then the high-temperature and high-pressure gaseous refrigerant enters the condenser tube 2 306, exchanges heat with the external environment through the heat sink, and is cooled to a high-pressure liquid state. Then, the liquid refrigerant is depressurized and cooled by the throttling device, and enters the evaporator to absorb the heat of the water in the water injection box 301, which greatly reduces the temperature of the water. These low-temperature waters circulate inside the air source heat pump unit 1 through the condenser tube 1 303, taking away the heat generated by the heating elements such as motors and circuit boards in the unit, maintaining its operating temperature within a reasonable range, reducing the performance degradation and failure rate caused by overheating, and improving the operating efficiency of the air source heat pump unit 1. At the same time, the condenser tube 2 306 is closely attached to the bottom of the photovoltaic power generation panel 2, continuously absorbing the heat generated by the photovoltaic power generation panel 2 when it is working, and reducing its surface temperature. Since the power generation efficiency of the photovoltaic power generation panel 2 is extremely sensitive to temperature, the cooling measures can significantly reduce the energy loss of the photovoltaic power generation panel 2 and improve the power generation efficiency.

[0029] In daily operation, when the external wind force reaches a certain intensity, the fan blade 603 is driven by the wind and starts to rotate. The fan blade 603 is coaxially connected to the reciprocating screw 602, so the rotation of the fan blade 603 will drive the reciprocating screw 602 to rotate synchronously. The threaded block 605 is matched with the reciprocating screw 602 through a thread. During the rotation of the reciprocating screw 602, the threaded block 605 moves up and down along the axial direction of the screw. At the same time, the slider 606 can only slide along a straight line under the restriction of the guide rod 607, ensuring that the brush plate 604 always remains stable during the movement. With the movement of the threaded block 605 and the slider 606, the brush plate 604 moves up and down close to the outside of the outer mesh cover 8, and the dust, debris, etc. attached to the surface of the outer mesh cover 8 are cleaned up. The outer mesh cover 8 serves as a protective barrier for the air source heat pump unit 1. If too much dust accumulates on the surface, the air circulation resistance will increase, resulting in an increase in the energy consumption of the unit. By regularly cleaning the brush plate 604, the smoothness of air circulation can be effectively restored, avoiding the unit from consuming extra energy due to poor ventilation.

[0030] While the brush plate 604 is cleaning, the rotation of the reciprocating lead screw 602 will also drive the cam 705 to rotate synchronously. During the rotation of the eccentric contour of the cam 705, the sliding rod 702 is continuously pushed to move. When the convex part of the cam 705 contacts the sliding rod 702, the sliding rod 702 moves into the air cylinder 701 against the elastic force of the spring 704, driving the piston 703 to compress the air in the air cylinder 701, so that the air pressure in the air cylinder 701 increases. At this time, the one-way valve at the air inlet 706 closes, and the one-way valve at the air outlet pipe 707 opens. The compressed air is quickly transported to the jet frame 708 through the air outlet pipe 707 and is ejected at high speed from the nozzles of the jet frame 708, forming a strong air flow. This air flow can completely disperse the dust raised during the cleaning process of the brush plate 604, preventing the dust from adhering to the surface of the outer mesh cover 8 again, and further improving the dust cleaning effect.

[0031] When the external wind force is insufficient and the fan blade 603 cannot rotate effectively, the electric energy stored in the energy storage device 501 comes into play. The motor 608 is powered by the second wire 503, and the motor 608 drives the reciprocating lead screw 602 to rotate, driving the brush plate 604 and the cam 705 to operate, realizing active dust cleaning; at the same time, the refrigeration device 304 is powered by the first wire 502 to maintain the cooling function of the air source heat pump unit 1 and the photovoltaic panel 2, ensuring that the system can operate stably and efficiently under different environmental conditions.

[0032] In addition, the assembly cover 401 adopts a unique snap - type design. When it is necessary to repair the second condenser pipe 306, just hold the assembly cover 401 and pull it outward horizontally with force, so that the frustum - shaped clamping block 404 disengages from the clamping groove 405, and the assembly cover 401 can be quickly disassembled, facilitating technicians to inspect, repair and replace the second condenser pipe 306, greatly shortening the equipment maintenance time and improving the maintainability and service life of the equipment.

[0033] Working principle: First, the photovoltaic power generation panel 2 absorbs solar energy to directly supply power to the air source heat pump unit 1, and stores part of the power in the power storage device 501. When the photovoltaic power generation panel 2 and the air source heat pump unit 1 are operating, the refrigeration device 304 cools the water introduced into the water injection box 301 from the water injection port 302, and the second condenser pipe 306 can cool the photovoltaic power generation panel 2 in the working state to reduce energy loss. Moreover, the refrigeration device 304 cools the heating elements inside the air source heat pump unit 1, so as to further improve the working efficiency of the air source heat pump unit 1; In addition, when the fan blade 603 rotates under the influence of external wind force, it can drive the reciprocating lead screw 602 to rotate, and then the threaded block 605 drives the brush plate 604 to move up and down, so as to clean the dust attached to the outer side of the outer mesh cover 8, which can avoid increasing the energy consumption of the air source heat pump unit 1. At the same time, the rotation of the reciprocating lead screw 602 can drive the cam 705 to rotate, push the sliding rod 702 to move and cooperate with the spring 704, so that the sliding rod 702 drives the piston 703 to move reciprocally, suck in air from the air inlet 706 and then transport it to the jet frame 708 through the air outlet pipe 707 to blow away the swept dust; When the external wind force is insufficient, the power stored in the power storage device 501 can directly act on the refrigeration device 304 for refrigeration and the motor 608 for active dust cleaning operation. Moreover, the assembly cover 401 can be disassembled by pulling forcefully, which is convenient for overhauling the second condenser pipe 306.
