Description

Technical Field

[0001] This patent belongs to the technical field of new energy and heat pump, and specifically relates to a split-frame solar absorption heat pump coupling system and a multi-mode collaborative control method. Background Art

[0002] In the technical field of new energy and heat pump, especially in building heating, cooling and industrial waste heat recovery, there are many problems with traditional absorption heat pump systems. Currently, solar collectors and heat pump units are usually designed independently, resulting in large losses during the energy transmission process and affecting the overall efficiency of the system. In addition, due to the intermittent nature of solar energy, when the system cannot obtain sufficient solar energy on cloudy days or at night, it needs to rely on auxiliary energy sources such as gas, which not only increases the operating cost but also leads to an increase in carbon emissions. The fixed heat pump system design has a significant drop in heat exchange efficiency when facing different working conditions, especially in high-temperature or high-humidity environments, and it is difficult to meet the actual needs.

[0003] After retrieval, a kind of air energy and solar energy composite intelligent clean energy device with the publication number CN111442547B was published on July 12, 2022. This patent combines a solar collector with an air source heat pump water heater unit, and introduces a heat collection and insulation water tank and a cleaning and filtering device to realize the combined utilization of solar energy and air energy, and effectively prevent the accumulation of sediment in the hot water pipeline. However, in this technical solution, the solar collector and the heat pump unit are designed independently, and there are large losses during the energy transmission process; in addition, due to the intermittent characteristics of solar energy, the system needs to rely on auxiliary energy sources (such as electricity or gas) to maintain stable operation, resulting in high carbon emissions, and the problem of the decline in heat exchange efficiency in high-temperature or high-humidity environments has not been fully solved.

[0004] After retrieval, a solar-assisted heat pump and phase change energy storage integrated heating system with the publication number CN107726425B was published on September 17, 2019. This patent combines a solar photovoltaic and solar thermal collector with a heat pump system and introduces a phase change energy storage unit, which significantly reduces the power consumption of the heat pump and improves the utilization rate of off-peak electricity at the same time. However, in this technical solution, the integration degree of the solar collector and the heat pump system is low, and the energy transfer path is long, resulting in limited overall efficiency of the system; in addition, although the design of the phase change energy storage unit can alleviate the solar energy intermittency problem to a certain extent, its adaptability to different working conditions is weak, especially in extreme climate conditions, the heat source stability and heat exchange efficiency of the system still need to be improved.

[0005] The above problems indicate that there are still certain deficiencies in the existing solar energy and heat pump coupling systems in terms of integration, heat source stability, heat transfer efficiency, etc. Therefore, the present invention provides a split-frame solar absorption heat pump coupling system and a multi-mode collaborative method, aiming to improve the energy coupling efficiency of solar energy and heat pumps, enhance the adaptability of the system to different working conditions, and achieve multi-mode collaborative operation by optimizing the system structure design, so as to meet the requirements of the modern energy field for high-efficiency, low-carbon, and intelligent heat pump systems. Summary of the Invention

[0006] In view of the deficiencies in the existing solar energy and heat pump coupling systems in terms of integration, heat source stability, heat transfer efficiency, etc., which lead to poor adaptability and low energy utilization efficiency of the system in multi-mode operation, the present application proposes a split-frame solar absorption heat pump coupling system and a multi-mode collaborative control method. The system realizes the efficient coupling utilization of multiple energy sources such as solar energy and geothermal energy through modular design and intelligent collaborative optimization, and significantly improves the stability and energy efficiency performance of the system under different working conditions.

[0007] The present application provides a split-frame solar absorption heat pump coupling system, including an independent heat source module, a multi-energy coupling module, a heat source stability analysis module, a phase change heat storage cascade utilization module, an intelligent mode switching module, an energy efficiency optimization module, and a remote operation and maintenance module. Each module is connected through a standardized interface to form an integrated system architecture, supporting rapid assembly and disassembly, while reducing energy transmission losses.

[0008] The independent heat source module is used to design the solar collector, the ground heat exchanger, and the phase change heat storage tank as detachable independent frame modules. Among them, the modular frame structure design supports the independent installation and rapid replacement of the solar heat collection array, the ground heat exchanger, and the phase change heat storage tank. Further, the independent frame module of the solar collector has the function of automatically tracking the sun's altitude and can adjust the angle in real time according to the change of the sun's position to maximize the solar energy absorption efficiency. Further, the standardized interface design reduces the connection loss between modules, and the embedded controller monitors the operation status of the module in real time and feeds back data to ensure the precise control of the system operation parameters. The modular design enables the system to flexibly configure heat source equipment according to actual needs, reducing installation and maintenance costs.

[0009] The multi - energy coupling module is used to dynamically switch between the solar - driven mode, the ground - source heat pump mode, or the hybrid mode according to the real - time working conditions, and generate an optimal energy utilization plan. Further, the module determines the energy transfer path between the solar collector and the buried - pipe heat exchanger, and optimizes the energy distribution ratio based on the path loss analysis. In particular, the double - loop U - shaped buried - pipe design reduces the thermal resistance during the geothermal extraction process and improves the geothermal utilization rate. Combining with the cascade heat - release characteristics of the phase - change heat - storage tank, a multi - energy collaborative utilization plan is generated to ensure the efficient operation of the system under different working conditions.

[0010] The heat - source stability analysis module is used to evaluate the heat - source stability of the system under different climate conditions and establish a heat - source stability index. Among them, based on the historical operation data and real - time sensor data, the heat - source stability of the system under extreme climate conditions is analyzed. Further, the module guides the system operation - mode switching through the heat - source stability index to ensure the reliable operation of the system under complex working conditions.

[0011] The phase - change heat - storage cascade utilization module is used to store the solar - energy waste heat by using the paraffin / expanded graphite composite phase - change material and release heat at night to drive the heat - pump generator. Further, based on the adjustable melting - point characteristics of the paraffin / expanded graphite composite phase - change material, by changing the type of paraffin, the content and dispersion mode of expanded graphite, a heat - storage unit with a melting - point range of 50°C to 80°C is designed to ensure effective heat storage and release under different working conditions. Experimental data showing a 30% increase in the heat - storage density is measured, and its heat - release performance under extreme climate conditions is verified. Combining with the operation parameters of the heat - pump main unit, the heat - release rate and temperature - matching strategy of the heat - storage tank are optimized to ensure the efficient connection of the heat - storage and heat - release processes.

[0012] The intelligent mode - switching module is used to dynamically adjust the operation mode based on the data of the light intensity, ambient temperature and humidity, and working - fluid concentration sensors. Further, historical operation data is collected to establish a correlation model between the light intensity, ambient temperature and humidity, and the system energy - efficiency ratio. The operation parameters of the heat - pump main unit are dynamically adjusted through the fuzzy PID algorithm to ensure the efficient operation of the system under different working conditions. Combining with the weather - forecast data, the operation - mode switching strategy for the next 12 hours is planned in advance to reduce the system operation energy consumption.

[0013] The energy - efficiency optimization module is used to predict the energy demand for the next 12 hours through the AI algorithm, preferentially call low - grade energy, and optimize the system operation strategy. Further, based on the historical energy - demand data, an energy - demand prediction model is constructed. The availability of low - grade energy (such as geothermal energy) is analyzed through the AI algorithm, and an emergency operation plan for extreme weather is formulated in combination with the biomass - energy backup heat source. Through the weighted calculation of the system operation energy consumption and carbon emissions, a comprehensive energy - efficiency optimization index is generated to ensure low - carbon operation while meeting the user's needs.

[0014] The remote operation and maintenance module is used to achieve remote monitoring and fault diagnosis of the system through the Internet of Things communication module. Further, the Internet of Things communication module accesses the Internet through a wireless network, receives real-time weather forecast data, and uploads the system operation status to the cloud server. It has a fault diagnosis function, can identify abnormal operation states, and send alarm signals to the terminal devices of operation and maintenance personnel to ensure the reliability of system operation.

[0015] This application also provides a multi-mode cooperation method for a split-frame solar absorption heat pump coupling system, including the following steps:

[0016] S1, Design the solar collector, ground-coupled heat exchanger, and phase change heat storage tank as detachable independent frame modules, supporting rapid assembly and disassembly;

[0017] S2, Dynamically switch the solar-driven mode, ground-source heat pump mode, or hybrid mode according to real-time working conditions to generate an optimal energy utilization plan;

[0018] S3, Evaluate the heat source stability of the system under different climate conditions and establish heat source stability indicators;

[0019] S4, Use paraffin / expanded graphite composite phase change materials to store solar waste heat and release heat at night to drive the heat pump generator;

[0020] S5, Dynamically adjust the operation mode based on the data of light intensity, ambient temperature and humidity, and working medium concentration sensors;

[0021] S6, Predict the energy demand in the next 12 hours through an AI algorithm, preferentially call low-grade energy, and optimize the system operation strategy;

[0022] S7, Achieve remote monitoring and fault diagnosis of the system through the Internet of Things communication module.

[0023] The working process of the present invention is divided into two operating states: refrigeration mode and heating mode. In the refrigeration mode, the solar collector array heats the working medium and drives the absorption refrigeration cycle, and the cooling capacity is delivered to the user end through the condenser. When solar energy is insufficient, the ground-source heat pump is started as an auxiliary cold source. Further, the waste heat is stored in the phase change heat storage tank, and at the same time, the ground-coupled heat exchanger absorbs the ambient heat to supplement the geothermal reservoir and serves as the solar-driven refrigeration heat source at night. When both solar energy and the ground-source heat pump cannot meet the refrigeration demand, the ground-source heat pump supplies the cooling capacity alone, and when it is not enough, the ground-source heat pump supplements it. In the heating mode, the phase change heat storage tank releases heat to drive the heat pump generator, the ground-source heat pump supplements heat, and hot water is output through the condenser for heating.

[0024] The beneficial effects of the present invention are reflected in multiple aspects. First, through the split-frame modular design, the system realizes the efficient integration of the solar collector, the ground heat exchanger, and the phase change heat storage tank, reducing the energy transmission loss. Second, the multi-energy complementary coupling mechanism makes full use of solar energy, geothermal energy, and phase change heat storage, reducing the dependence on auxiliary energy and significantly reducing the use of fossil fuels. Finally, the intelligent mode switching system dynamically adjusts the operation mode through the linkage of multiple sensors and the AI energy efficiency optimization algorithm, improving the adaptability of the system under different working conditions. Further, the Internet of Things communication module supports remote operation and maintenance and energy efficiency monitoring, extending the service life of the equipment and reducing the maintenance cost.

[0025] In summary, through modular design and intelligent collaborative optimization, the present invention realizes the efficient coupling utilization of multiple energies such as solar energy and geothermal energy, and significantly improves the stability and energy efficiency performance of the system under different working conditions, so as to meet the requirements of the modern energy field for high-efficiency, low-carbon, and intelligent heat pump systems.

Detailed implementation manners

[0034] The present invention provides a split-frame solar absorption heat pump coupling system and a multi-mode cooperative control method. With reference to Figure 1 to Figure 6 the detailed implementation manners of the present invention will be described in detail.

[0035] As Figure 1 shown, the overall system of the present invention consists of a split heat source module, a heat pump main unit and an intelligent control box. Each module is connected through a standardized interface to form an integrated architecture. The split heat source module includes a solar heat collection array 1, a buried pipe heat exchanger 2 and a phase change heat storage tank 3. The heat pump main unit includes an absorption refrigeration cycle 4 and a compression heat pump auxiliary unit 5. The intelligent control box integrates an embedded controller 6 and an Internet of Things communication module 7.

[0036] The implementation manner of the split heat source module is as Figure 2 shown. The solar heat collection array 1 is connected to the generator 11 through a heat-conducting working fluid pipeline to convert the collected solar energy into heat energy to drive the absorption refrigeration cycle 4. The solar heat collection array 1 adopts a high-efficiency flat plate collector design, and its surface is coated with a selective absorption coating, which can achieve high-efficiency energy capture under different lighting conditions. The buried pipe heat exchanger 2 adopts a double-loop U-shaped design 8. As Figure 5 shown, its buried depth ranges from 80 meters to 120 meters and is used to extract or store heat through underground heat exchange. The double-loop design significantly reduces the thermal resistance and improves the geothermal utilization rate. The phase change heat storage tank 3 is filled with a paraffin / expanded graphite composite phase change material 9, and its melting point range is from 50 °C to 80 °C. As Figure 6 shown, a multi-layer partition structure 10 is arranged inside to reduce heat convection loss and improve the heat storage density. Experimental measurements show that the heat storage density of this phase change material is increased by 30% compared with traditional materials and can stably release heat under extreme climate conditions.

[0037] The implementation manner of the heat pump main unit is as Figure 3As shown in the figure, the absorption refrigeration cycle 4 includes a generator 11, a condenser 12, an evaporator 13, and an absorber 14, forming an integrated design. The generator 11 receives the thermal energy from the solar heat collection array 1 and drives the operation of the absorption refrigeration cycle 4. The cooling capacity is delivered to the user end through the condenser 12. When the solar energy is insufficient, the compression heat pump auxiliary unit 5 is started as a supplementary cold source. The compression heat pump auxiliary unit 5 extracts the ambient heat through the buried pipe heat exchanger 2 to further improve the energy utilization efficiency of the system. In the heating mode, the phase change heat storage tank 3 releases heat to drive the generator 11, and the buried pipe heat exchanger 2 supplements heat and outputs hot water through the condenser 12 for heating.

[0038] The implementation of the intelligent control box is as Figure 4 shown. The embedded controller 6 integrates the fuzzy PID algorithm and dynamically adjusts the system operation parameters based on the real-time data collected by the light intensity sensor 15, the ambient temperature and humidity sensor 16, and the working fluid concentration sensor 17. The Internet of Things communication module 7 accesses the Internet through the wireless network, receives the real-time weather forecast data, and uploads the system operation status to the cloud server. The intelligent control box has a fault diagnosis function and can identify abnormal operation states and send alarm signals to the maintenance personnel's terminal devices. For example, when the working fluid concentration sensor 17 detects that the working fluid concentration deviates from the set value, the embedded controller 6 automatically adjusts the working fluid flow rate to ensure the stable operation of the system.

[0039] The present application also provides a multi-mode collaborative method for the split-frame solar absorption heat pump coupling system, as Figure 7 shown, including the following steps:

[0040] S1, design the solar collector, the buried pipe heat exchanger, and the phase change heat storage tank as detachable independent frame modules to support rapid assembly and disassembly;

[0041] S2, dynamically switch the solar drive mode, the ground source heat pump mode, or the hybrid mode according to the real-time working conditions to generate the optimal energy utilization plan;

[0042] S3, evaluate the heat source stability of the system under different climate conditions and establish a heat source stability index;

[0043] S4, store the solar waste heat using the paraffin / expanded graphite composite phase change material and release the heat at night to drive the heat pump generator;

[0044] S5, dynamically adjust the operation mode based on the data of the light intensity, the ambient temperature and humidity, and the working fluid concentration sensors;

[0045] S6, predict the energy demand in the next 12 hours through the AI algorithm, give priority to calling low-grade energy, and optimize the system operation strategy;

[0046] S7 realizes remote monitoring and fault diagnosis of the system through the Internet of Things communication module.

[0047] The working process of the present invention is divided into two operating states: refrigeration mode and heating mode. In the refrigeration mode, the solar heat collection array 1 heats the working medium and drives the absorption refrigeration cycle 4, and the cold quantity is delivered to the user end through the condenser 12. When the light intensity sensor 15 detects insufficient solar energy, the compression heat pump auxiliary unit 5 is started as an auxiliary cold source. The waste heat is stored in the phase change heat storage tank 3, and at the same time, the ground heat exchanger 2 absorbs the ambient heat to supplement the geothermal reservoir and serves as the solar-driven refrigeration heat source at night. At the same time, combined with the adsorption refrigerant concentration detection device, the refrigerant concentration is monitored in real time. When both solar energy and ground source heat pump cannot meet the refrigeration demand, the compression heat pump auxiliary unit 5 supplies cold quantity alone. In the heating mode, the phase change heat storage tank 3 releases heat to drive the generator 11, and the ground heat exchanger 2 supplements heat and outputs hot water through the condenser 12 for heating. The intelligent control box establishes an association model of light intensity, ambient temperature and humidity, and system energy efficiency ratio based on historical operation data and real-time sensor data, and dynamically adjusts the operation parameters of the heat pump main unit through the fuzzy PID algorithm to ensure the efficient operation of the system under different working conditions.

[0048] The multi-energy coupling mechanism of the present invention realizes efficient energy utilization by optimizing the energy transfer path. For example, the energy transfer path between the solar heat collection array 1 and the ground heat exchanger 2 optimizes the energy distribution ratio after path loss analysis. The double-loop U-shaped ground heat exchanger design 8 significantly reduces the thermal resistance in the geothermal extraction process and improves the geothermal utilization rate. Combining the cascade heat release characteristics of the phase change heat storage tank 3, a multi-energy collaborative utilization scheme is generated to ensure the efficient operation of the system under different working conditions. Under extreme climate conditions, the heat source stability analysis module analyzes the heat source stability of the system based on historical operation data and real-time sensor data, establishes a heat source stability index, and guides the switching of the system operation mode. For example, in continuous rainy weather, the system preferentially uses the geothermal resources of the ground heat exchanger 2 and formulates an emergency operation plan in combination with the biomass energy backup heat source.

[0049] The energy efficiency optimization module of the present invention predicts the energy demand in the next 12 hours through the AI algorithm, preferentially calls low-grade energy and optimizes the system operation strategy. For example, an energy demand prediction model is constructed based on historical energy demand data, the availability of low-grade energy such as geothermal energy is analyzed through the AI algorithm, and an emergency operation plan under extreme weather is formulated in combination with the biomass energy backup heat source. Through the weighted calculation of the system operation energy consumption and carbon emissions, a comprehensive energy efficiency optimization index is generated to ensure low-carbon operation while meeting the user's needs. For example, during the peak heating period in winter, the system preferentially uses the geothermal resources of the ground heat exchanger 2 and optimizes the heating strategy in combination with the heat release characteristics of the phase change heat storage tank 3 to reduce the system operation energy consumption.

[0050] The remote operation and maintenance module realizes the remote monitoring and fault diagnosis of the system through the Internet of Things communication module 7. For example, the Internet of Things communication module 7 receives real-time weather forecast data and uploads the system operation status to the cloud server, and the operation and maintenance personnel can view the system operation status in real time through the terminal device. When the system detects an abnormal operation status, the Internet of Things communication module 7 automatically sends an alarm signal to the operation and maintenance personnel's terminal device to ensure the reliability of the system operation. For example, when the environmental temperature and humidity sensor 16 detects that the environmental temperature is lower than the set value, the system automatically adjusts the operation mode and notifies the operation and maintenance personnel to conduct an inspection. If the fault may cause equipment damage or endanger the system safety, the system can automatically enter the protection mode and shut down, while notifying the operation and maintenance personnel to handle it in time.

[0051] The present invention has wide applicability in practical applications. For example, in the field of building heating, the system makes full use of solar energy, geothermal energy and phase change heat storage through the multi-energy complementary coupling mechanism, reduces the dependence on auxiliary energy, and significantly reduces the use of fossil fuels. In the aspect of industrial waste heat recovery and utilization, the system dynamically adjusts the operation mode through the intelligent mode switching and AI energy efficiency optimization algorithm, and improves the adaptability of the system under different working conditions. In the agricultural greenhouse heating scenario, the system supports remote monitoring and energy efficiency monitoring through the remote operation and maintenance module, extends the service life of the equipment and reduces the maintenance cost.

[0052] In summary, the present invention realizes the efficient integration of the solar collector, the buried pipe heat exchanger and the phase change heat storage tank through the split-frame modular design, reducing the energy transmission loss. The multi-energy complementary coupling mechanism makes full use of solar energy, geothermal energy and phase change heat storage, reduces the dependence on auxiliary energy, and significantly reduces the use of fossil fuels. The intelligent mode switching system dynamically adjusts the operation mode through the multi-sensor linkage and the AI energy efficiency optimization algorithm, improving the adaptability of the system under different working conditions. The Internet of Things communication module supports remote operation and maintenance and energy efficiency monitoring, extends the service life of the equipment and reduces the maintenance cost. The present invention realizes the efficient coupling utilization of multiple energies such as solar energy and geothermal energy through modular design and intelligent collaborative optimization, and significantly improves the stability and energy efficiency performance of the system under different working conditions, meeting the requirements of the modern energy field for high-efficiency, low-carbon and intelligent heat pump systems.
