Description

Technical Field

[0001] This utility model mainly relates to the field of solar thermal utilization technology, specifically a solar energy storage and air energy control system auxiliary heating device. Background Technology

[0002] Existing traditional heating equipment, such as wood-burning, coal-burning, and natural gas-fired stoves, has a significant impact on environmental pollution, poses uncontrollable safety hazards, has relatively low thermal efficiency, and is inconvenient for fuel storage; electric heating furnaces and air conditioners that rely on electricity consume a lot of electricity and have high operating costs.

[0003] With the escalating global energy crisis and heightened emphasis on environmental protection, traditional heating methods are increasingly being restricted due to their high energy consumption and environmental pollution. Solar energy, as a clean and renewable energy source, is inexhaustible, but its energy supply is unstable at night or during cloudy / rainy weather. Air source heat pumps can utilize the heat energy in the air for heating, but their efficiency when used alone is significantly affected by ambient temperature. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a solar energy storage and air energy control system-assisted heating device. Through modular design, it combines solar energy and air energy, and optimizes the heat transfer path and control logic through an effective energy storage and control system. This fully leverages the advantages of both technologies, compensates for the deficiencies of single-energy heating, and achieves efficient, stable, and energy-saving heating. It has significant practical implications and broad application prospects.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A solar energy storage and air source heat pump control system auxiliary heating device includes a heating water tank, a heat transfer medium tank, an air source heat pump heating device, a support frame, a solar heating device, an energy storage water tank, and a control device. The heating water tank, heat transfer medium tank, air source heat pump heating device, and solar heating device are fixedly installed on the support frame. A heat exchange pipeline is provided between the heating water tank and the solar heating device. The heat exchange pipeline is also connected to the heat transfer medium tank. A heat transfer agent circulates in the heat exchange pipeline. A second heat exchange pipeline is provided between the heating water tank and the air source heat pump heating device. A third heat exchange pipeline is connected between the heating water tank and the energy storage water tank. The control device is electrically connected to the air source heat pump heating device and the solar heating device. The heating water tank also contains a domestic water heat exchange pipeline.

[0007] The heat exchange pipeline is connected between the heating water tank and the solar heating device. The solar heating device has a solar heating tube, which is connected to the heat exchange pipeline. The heating water tank is equipped with a spiral tube, which is connected to the spiral tube. The heat transfer medium in the solar heating tube is spiral in shape.

[0008] A drive pump set is provided on one side of the heating water tank. The drive pump set is electrically connected to the control device. The drive pump set includes a drive pump one, a compressor, and a drive pump two. The drive pump one controls the flow of heat transfer fluid in heat exchange pipeline one, the compressor controls the flow of heat transfer fluid in heat exchange pipeline two, and the drive pump two controls the flow of heat transfer fluid in heat exchange pipeline three.

[0009] The heat-conducting medium tank is equipped with a heat-conducting medium inlet and a pressure balancing valve.

[0010] Compared with the existing technology, the beneficial effects of this utility model are:

[0011] This invention can comprehensively utilize two renewable energy sources, solar energy and air energy, and achieve energy storage and regulation through an energy storage system, thereby avoiding energy waste and improving the overall efficiency of energy utilization. Compared with traditional single-energy heating methods, it can significantly reduce energy consumption and operating costs.

[0012] The spiral heat-conducting tubing in the solar vacuum heating tube can effectively improve the heating efficiency of the heat-conducting agent and increase the amount of solar heat absorbed.

[0013] The control system can automatically switch between multiple heating modes according to different environmental conditions and user needs, and optimize and adjust the operation of each system to ensure that the required heat can be stably provided under various operating conditions, unaffected by weather changes and energy supply fluctuations, thereby improving the reliability and comfort of the heating system.

[0014] Both solar and air energy are clean energy sources that do not produce pollutant emissions during use. They are environmentally friendly, meet the requirements of sustainable development, and help reduce greenhouse gas emissions, alleviate the energy crisis and environmental pollution problems.

[0022] Combined with appendix Figures 1-5 A solar energy storage and air energy control system auxiliary heating device includes a heating water tank 1, a heat transfer medium tank 2, an air energy heating device 3, a support frame 4, a solar heating device 6, an energy storage water tank 10, and a control device 7. The heating water tank 1, the heat transfer medium tank 2, the air energy heating device 3, and the solar heating device 6 are fixedly installed on the support frame 4. A heat exchange pipeline 21 is provided between the heating water tank 1 and the solar heating device 6. The heat exchange pipeline 21 is also connected to the heat transfer medium tank 2. A heat transfer agent circulates in the heat exchange pipeline 21. A heat exchange pipeline 30 is provided between the heating water tank 1 and the air energy heating device 3. A heat exchange pipeline 100 is connected between the heating water tank 1 and the energy storage water tank 10. The control device 7 is electrically connected to the air energy heating device 3 and the solar heating device 6. The heating water tank 1 is also provided with a domestic water heat exchange pipeline. The control device 7 is a microcontroller-based control device. It features a display screen and several control buttons for human-machine interaction. The control device 7 is also electrically connected to the valve bodies, drive pumps, temperature sensors, and other components of each part. Both the heating water tank 1 and the solar heating device 6 are equipped with corresponding temperature sensors, as well as a temperature sensor for monitoring ambient temperature, all electrically connected to the control device 7. The top of the solar heating device 6 is also equipped with a return pipe 9, on which an electromagnetic control valve 8 is installed to control the return flow of the heat transfer fluid.

[0023] The heat exchange pipeline 21 is connected between the heating water tank 1 and the solar heating device 6. The solar heating device 6 has a solar heating tube 60, which is connected to the heat exchange pipeline 21. The heating water tank 1 is provided with a spiral tube 5, which is connected to the spiral tube 5. The heat transfer medium pipeline in the solar heating tube 60 is spiral in shape. The spiral heat transfer medium pipeline in the vacuum heating tube 60 can effectively improve the heating efficiency of the heat transfer agent.

[0024] A drive pump set is provided on one side of the heating water tank 1. The drive pump set is electrically connected to the control device 7. The drive pump set includes drive pump one 11, compressor 12, and drive pump two 13. Drive pump one 11 controls the flow of heat transfer fluid in heat exchange pipeline one 21, compressor 12 controls the flow of heat transfer fluid in heat exchange pipeline two 30, and drive pump two 13 controls the flow of heat transfer fluid in heat exchange pipeline three 100. Each drive pump is also provided with a corresponding electrically controlled valve.

[0025] The heat transfer medium tank 2 is equipped with a heat transfer medium inlet 20 and a pressure balancing valve. The heat transfer medium tank 2 is used to supply additional heat transfer medium to the heat exchange pipeline and to recover a portion of the heat transfer medium. A corresponding drive pump is installed on the pipeline connecting the heat transfer medium tank 2 and the heat exchange pipeline to replenish and recover the heat transfer medium. The heat transfer medium can be oil, which can be heated to a high temperature and can efficiently exchange heat with water.

[0026] Control methods:

[0027] ①Solar priority mode:

[0028] When the temperature of the heat transfer agent in the solar heating device 6 is higher than the set temperature A, the control device 7 controls the drive pump 11 to work, so that the heat transfer agent in the heat exchange pipeline 21 circulates and transfers heat from the solar heating device 6 to the heating water tank 1. When the temperature of the heat transfer agent in the solar heating device 6 is higher than the set upper temperature limit B, the control device controls the drive pump 11 to stop working to avoid excessive water temperature and the generation of more scale. The set temperature A is 80℃.

[0029] When the temperature of the water in the heating water tank 1 is ≥55℃, the control device 7 controls the drive pump 2 13 to work. The drive pump 2 13 makes the heat transfer agent in the heat exchange pipeline 3 100 circulate, transferring the heat of the water in the heating water tank 1 to the energy storage water tank 10, and storing the excess heat.

[0030] When the temperature of the heat transfer medium in the solar heating device 6 is higher than the set temperature H for a set time G, all the heat transfer medium is returned to the heat transfer medium box 2, and the heat transfer medium in the solar heating device 6 is emptied to prevent the heat transfer medium from carbonizing due to excessive temperature.

[0031] When solar heating is insufficient and the water temperature in the heating tank 1 is lower than the set temperature C, the control device 7 controls the drive pump 11 to work in reverse, causing the heat transfer agent in the heat exchange pipeline 21 to circulate in reverse, transferring the hot water in the energy storage tank 10 to the heating tank 1, using the heat of the water in the energy storage tank 10 for heating or to meet the needs of domestic hot water; the set temperature C is 35℃.

[0032] ② Air source heat pump auxiliary mode:

[0033] When the water temperature in the energy storage tank 10 is lower than the set temperature D, the control device 7 controls the start of the air source heating device 3. The compressor 12 drives the heat transfer agent in the heat exchange pipeline 30 to circulate and obtain heat from the air to heat the water in the heating tank 1 to the set temperature E and then stop. The set temperature D is 20℃ and the set temperature E is 50℃.

[0034] The air source heat pump heating device 3 automatically adjusts its output power according to the outdoor temperature. When the outdoor temperature is lower than the set temperature F, it starts the high-frequency mode, operates at high power, and heats up quickly. The set temperature F is 10℃.

[0035] Energy storage tank 10 heat management:

[0036] When the temperature of the heating water tank 1 is higher than that of the energy storage water tank 10, the control system 7 can control the transfer of heat to the energy storage water tank 10.

[0037] Stop transferring energy when the temperature of the energy storage tank reaches ≥55℃ to avoid overheating.

[0038] For example, in summer, the solar heating device keeps five sets of heat transfer media running normally to ensure sufficient water temperature for bathing, while the remaining part is pumped into the media tank and stopped to avoid excessive temperature and reduced lifespan of the heat transfer media.

[0039] Tiered energy storage strategy: The transfer of hot water between the heating tank and the energy storage tank is controlled by temperature thresholds to improve the stability of heating supply.

[0040] The heat transfer medium box 2 is located above the air source heating device 3, and the heating water tank 1 is located on one side of the air source heating device 3. The heating water tank 1 is connected to the energy storage water tank 10 through a heat exchange pipeline.

[0041] Air source heat pump heating device 3 is a relatively mature existing technology, and its principle will not be elaborated here. Air source heat pump heating device 3 can also be replaced by light wave tube heating, induction heating, etc.

[0042] The heating water tank has a spiral coil for tap water. When tap water flows into the coil, the outer wall of the coil exchanges heat with the hot water in the heating water tank 1. The heated water meets the needs of domestic hot water such as bathing.

[0043] Example:

[0044] Taking a 120㎡ residential building in North China as an example:

[0045] 1. Equipment Configuration:

[0046] The solar heating device 6 contains 20 solar heating tubes and a heat transfer medium box with a capacity of 50L.

[0047] The air source heat pump heating device has a rated power of 5kW and is suitable for low-temperature environments down to -15℃.

[0048] The energy storage water tank has a capacity of 500L and an insulation layer thickness of 60mm.

[0049] 2. Running results:

[0050] The daily solar energy contribution rate is 70%, and the power consumption of air source heat pumps is only about 50% of that of traditional equipment.

[0051] In winter, the indoor temperature remains stable at 20℃±2℃.
