Description

Technical Field

[0001] This utility model relates to the technical field of heat pump unit equipment, and in particular to a dual-source solar air source heat pump unit. Background Technology

[0002] With ever-increasing energy demand and increasingly stringent environmental requirements, high-efficiency and energy-saving heating and cooling equipment has become a research hotspot. A dual-source solar-air source heat pump unit has emerged, which innovatively integrates two clean energy sources: solar energy and air energy. Through a unique energy conversion and utilization mechanism, it provides heating and cooling services for buildings. During operation, the unit can flexibly switch between solar and air energy working modes according to external environmental conditions and actual user needs, greatly improving energy utilization efficiency, reducing dependence on traditional fossil fuels, and contributing significantly to sustainable development.

[0003] Early dual-source solar-air source heat pump units mainly consisted of basic components such as solar collectors, air source heat pumps, water storage tanks, and connecting pipes. However, the solar collectors had low heat collection efficiency, and the air source heat pump's heating capacity significantly decreased in low-temperature environments. This resulted in extremely slow heating of the low-temperature, low-pressure refrigerant during unit operation, making it difficult to meet users' demands for rapid heating. With technological advancements, existing dual-source solar-air source heat pump units utilize high-efficiency flat-plate solar collectors and air source heat pump compressors with enthalpy-increasing technology, improving unit performance and alleviating some of the slow heating issues. However, due to… Existing flat-plate solar collectors can only collect limited solar heat in cloudy or low-light conditions. They can only accumulate heat by extending the time of light absorption to prevent the refrigerant from heating up. However, under low-temperature and low-pressure conditions, the surface of the evaporator is prone to frost formation as the refrigerant absorbs heat, hindering heat transfer. Existing defrosting devices mostly use hot gas bypass defrosting. In this process, the high-temperature and high-pressure gas flowing through the evaporator for defrosting will consume the heat originally used to heat the refrigerant, further prolonging the heating time of the low-temperature and low-pressure refrigerant in the evaporator. This makes it impossible to provide users with a stable and efficient heating experience with rapid temperature rise. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a dual-source solar-air source heat pump unit, comprising a frame 1. A compression cylinder 3 is fixedly connected to the front and rear sides of the bottom inner wall of the frame 1. A circulation pump 4 is fixedly connected to the middle left side of the inner wall of the frame 1. Connecting pipes 5 connect the front and rear sides of the circulation pump 4. When the circulation pump 4 starts operating, it is connected to the left side of the corresponding compression cylinder 3. Driven by the circulation pump 4, cooling material is extracted from the compression cylinder 3. The other end of the connecting pipe 5 is connected to the left side of the corresponding compression cylinder 3. Insulation pipes 6 connect to the left and right sides of the outer wall of the front compression cylinder 3. A bracket 8 is fixedly connected to the middle top of the frame 1. A concave concentrator mirror 9 is fixedly connected to the top of the bracket 8. The concave concentrator mirror 9 collects and focuses solar energy onto a heat-absorbing ball 7, allowing the heat-absorbing ball 7 to absorb a large amount of solar radiation energy. The working fluid is further heated. The other end of the insulation pipes 6 on both sides passes through the concave mirror 9 and is connected to the heat-absorbing ball 7. The insulation pipes 6 transport the working fluid to the heat-absorbing ball 7 located in the center area of ​​the concave mirror 9. The concave mirror 9 is fixed to the top of the frame 1 by the bracket 8. The left and front sides of the frame 1 are rotatably connected to the inspection door 10, which provides convenience for the daily maintenance and repair of the equipment. The top left and right sides of the frame 1 are connected to the exhaust port 11. The top of the exhaust port 11 is fixedly connected to the interception net 12. The exhaust port 11 and the interception net 12 can discharge the excess heat generated during the operation of the unit. The interception net 12 prevents foreign objects from entering the unit through the exhaust port 11, ensuring the stable operation of the unit. The outer wall of the insulation pipe 6 is provided with a heat dissipation mechanism 2, which is used to accelerate heat dissipation.

[0032] Specifically, the circulating pump 4 starts operating and is connected to the left side of the corresponding compression cylinder 3. Driven by the circulating pump 4, the cooling material is drawn from the compression cylinder 3 and enters the circulating pump 4 through the connecting pipe 5. It is then pressurized and pushed back into the compression cylinder 3 by the circulating pump 4, thus forming a continuous working fluid circulation flow within the system. At this time, the working fluid inside the compression cylinder 3 is compressed and transported to the heat-absorbing ball 7 located in the central area of ​​the concave mirror 9 through the heat insulation pipe 6. The concave mirror 9 is fixed to the top of the frame 1 by the bracket 8. The concave mirror 9 collects and focuses solar energy onto the heat-absorbing ball 7, causing heat absorption. Sphere 7 absorbs a large amount of solar radiation energy, which further heats the incoming working fluid, increasing its temperature and energy. As the working fluid circulates within the system, the inspection door 10 facilitates daily maintenance and repair of the equipment. Furthermore, the exhaust vent 11 and the interceptor net 12 can discharge excess heat generated during unit operation. The interceptor net 12 prevents foreign objects from entering the unit through the exhaust vent 11, ensuring stable unit operation. Through the cooperation of these structures, the dual-source solar-air source heat pump unit achieves efficient utilization of solar and air energy, providing users with stable heating and cooling services.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The heat dissipation mechanism 2 includes two spiral copper tubes 201. Heat is conducted to the spiral copper tubes 201. The special spiral shape of the spiral copper tubes 201 greatly increases the contact area with the outside air. The front ends of the two spiral copper tubes 201 are respectively connected to the outer wall of the insulation pipe 6. Multiple connecting pipes 202 are connected to adjacent sides of the two spiral copper tubes 201. The connecting pipes 202 allow the working fluid in the two spiral copper tubes 201 to circulate with each other, ensuring a more uniform heat distribution and further improving the heat dissipation effect. The inner walls of the frame 1 are fixedly connected to the left and right sides with solid... The top of the fixed plate 203 is fixedly connected to a cooling fan 204. The cooling fan 204 generates a strong wind to accelerate the air flow, so that the hot air around the spiral copper pipe 201 can be quickly carried away, while cold air is constantly replenished, forming good air convection, thereby significantly improving the heat dissipation efficiency. The right side of the frame 1 is connected to a fixed frame 205, and the right side of the fixed frame 205 is rotatably connected to multiple louvers 206. The louvers 206 will rotate appropriately according to the air flow and actual heat dissipation needs.

[0034] Specifically, when the high-temperature working fluid flows within the insulation pipe 6, heat is conducted to the spiral copper pipe 201. The special spiral shape of the spiral copper pipe 201 greatly increases the contact area with the outside air, enabling more efficient heat dissipation. Multiple connecting pipes 202 are connected to adjacent sides of the two spiral copper pipes 201, allowing the working fluid within the two spiral copper pipes 201 to circulate freely, ensuring a more uniform heat distribution and further improving the heat dissipation effect. The fixing plate 203 provides stable support for the cooling fan 204. When heat dissipation begins, the cooling fan 204, fixedly connected to the top of the fixing plate 203, starts operating. The cooling fan 204 generates a strong airflow, accelerating the airflow and causing the spiral copper pipe... The hot air around 201 can be quickly carried away, while cold air is constantly replenished, forming good air convection, which significantly improves the heat dissipation efficiency. The right side of the frame 1 is connected to the fixed frame 205, which connects the frame 1 to the outside world and provides a base for the installation of the louvered plate 206. When the cooling fan 204 is working, the louvered plate 206 will rotate appropriately according to the air flow and actual heat dissipation needs. On the one hand, it can adjust the direction and flow of air entering and exiting, so that the air can flow more rationally through the spiral copper pipe 201 and enhance the heat dissipation effect. On the other hand, when the unit is not working or it is necessary to reduce the entry of external impurities, the louvered plate 206 can be closed to play a protective role.

[0035] Reference Figure 1 , Figure 2 and Figure 4 Multiple observation windows 13 are provided on the outer wall of the compression cylinder 3, allowing operators to directly observe the internal working condition of the compression cylinder 3. An outer frame 14 is fixedly connected to the outer wall of the observation window 13, which prevents the observation window 13 from being damaged by the high-pressure environment inside the compression cylinder 3 or by possible external collisions and impacts. A heat-conducting plate 15 is fixedly connected to the front side of the frame 1, which can quickly conduct the heat generated inside the frame 1 to its surface. Multiple heat dissipation strips 16 are fixedly connected to the front side of the heat-conducting plate 15, which fully exchange heat with the outside air, accelerating the dissipation of heat into the surrounding environment. A column 17 is fixedly connected to the top front end of the frame 1, which can stably support the warning light 18 at a suitable height on the top front end of the frame 1, so that the warning light 18 can clearly display the signal at a high position. The warning light 18 is fixedly connected to the top of the column 17, which can issue a clear warning signal to the operator when the equipment malfunctions, reminding the operator to check the equipment in time.

[0036] Specifically, through the observation window 13, operators can intuitively observe the working condition inside the compressor cylinder 3. The outer frame 14 prevents the observation window 13 from being damaged by the high-pressure environment inside the compressor cylinder 3 or by possible external impacts, ensuring that the observation window 13 remains stable and intact so as to continuously perform its observation function. The heat conduction plate 15 can quickly conduct the heat generated inside the frame 1 to its surface. Due to the good thermal conductivity of copper alloy, it can efficiently collect heat. Through the heat dissipation strip 16, it can fully exchange heat with the outside air, accelerating the heat dissipation to the surrounding environment, thereby effectively reducing the temperature inside the frame 1, ensuring that the components inside the frame 1 operate stably within a suitable temperature range, and preventing the performance degradation or even damage of components due to overheating. The pillar 17 can firmly support the warning light 18 at a suitable height at the top front of the frame 1, so that the warning light 18 can clearly display the signal at a high position. Through the warning light 18, when the equipment has an abnormal condition, it can issue a clear warning signal to the operator, reminding the operator to check the equipment in time and take corresponding maintenance or troubleshooting measures to avoid further damage to the equipment and possible safety accidents.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A handle 19 is fixedly connected to the left side of the maintenance door 10. The handle 19 allows operators to easily open and close the maintenance door 10. A keyhole 20 is provided on the left side of the handle 19, which can improve the safety of the equipment. The inner wall of the frame 1 is rounded to reduce the accumulation of dust and impurities inside the frame 1. The inner wall of the concave mirror 9 is also rounded to improve the light reflection efficiency and reduce the scattering and loss of light during the reflection process. The size of the interception net 12 is the same as the size of the exhaust vent 11, which can completely cover the exhaust vent 11 to prevent foreign objects from entering. The circulation pump 4 is waterproofed to prevent liquid from penetrating into the interior of the circulation pump 4, avoiding damage to the electrical components and mechanical parts of the circulation pump 4 and extending the service life of the circulation pump 4.

[0038] Specifically, the handle 19 allows operators to easily open and close the maintenance door 10; the keyhole 20 enhances equipment safety; the rounded inner wall of the frame 1 reduces the accumulation of dust and impurities inside; the rounded inner wall of the concave mirror 9 improves light reflection efficiency and reduces scattering and loss during reflection; the size of the interceptor net 12 matches that of the exhaust vent 11, completely covering it to prevent foreign objects from entering; and the waterproof treatment of the circulating pump 4 prevents liquid from penetrating its interior, avoiding damage to its electrical and mechanical components and extending its service life.

[0039] Working principle: First, the circulating pump 4 starts running and is connected to the left side of the corresponding compression cylinder 3. Driven by the circulating pump 4, the cooling medium is drawn out from the compression cylinder 3 and introduced into the circulating pump 4 through the connecting pipe 5. Subsequently, the circulating pump 4 pressurizes the cooling medium and pushes it back to the compression cylinder 3, forming a continuous working fluid circulation within the system. At this time, the working fluid inside the compression cylinder 3 undergoes a compression process and is transported to the heat-absorbing ball 7 located in the central area of ​​the concave concentrating mirror 9 through the heat insulation pipe 6. The concave concentrating mirror 9 is fixed to the top of the frame 1 by the bracket 8 and is responsible for collecting and converging solar rays to the heat-absorbing ball 7, thus absorbing heat. Sphere 7 absorbs a large amount of solar radiation energy, which further heats the incoming working fluid, increasing its temperature and energy. As the working fluid circulates within the system, the inspection door 10 facilitates daily maintenance and repair of the equipment. In addition, the exhaust vent 11 and the interceptor net 12 can discharge excess heat generated during unit operation. At the same time, the interceptor net 12 prevents foreign objects from entering the unit through the exhaust vent 11, ensuring stable unit operation. Through the cooperation of these structures, the dual-source solar air source heat pump unit achieves efficient utilization of solar and air energy, providing users with stable heating and cooling services.

[0040] Furthermore, through the heat dissipation mechanism 2, the high-temperature working fluid flowing in the insulation pipe 6 conducts heat to the spiral copper pipe 201. Due to the special spiral shape of the spiral copper pipe 201, it significantly increases the contact area with the outside air, thereby dissipating heat more efficiently. The adjacent sides of the two spiral copper pipes 201 are connected to multiple connecting pipes 202. These connecting pipes 202 ensure that the working fluid in the two spiral copper pipes 201 can circulate with each other, thereby ensuring the uniformity of heat distribution and further improving the heat dissipation effect. The fixing plate 203 provides stable support for the cooling fan 204. When the heat dissipation work is started, the cooling fan 204 fixedly connected to the top of the fixing plate 203 starts to operate, generating a strong wind to accelerate the airflow. The movement of the spiral copper tube 201 allows the hot air around it to be quickly carried away while a constant influx of cool air creates good air convection, significantly improving heat dissipation efficiency. A fixed frame 205 connects to the right side of the frame 1, providing a base for the louvered plate 206. During operation of the cooling fan 204, the louvered plate 206 rotates appropriately according to airflow and actual heat dissipation needs. On one hand, it adjusts the direction and flow of air entering and exiting, allowing air to flow more efficiently through the spiral copper tube 201, enhancing heat dissipation. On the other hand, when the unit is not operating or when it is necessary to reduce the entry of external dust and impurities, the louvered plate 206 can be closed for protection.
