[0062] As shown in Figures 1-7 The main structure of the light and energy storage air conditioner all-in-one machine provided by the embodiments of the present application includes a case 100, a photovoltaic assembly 200, an air conditioning system, an energy storage device 400 and a control module 500. The case 100 is formed with a fan compartment 110, a compressor compartment 120, an energy storage compartment 130 and a controller compartment 140. The photovoltaic assembly 200 is connected to the case 100. The air conditioning system includes a compressor 310 arranged in the compressor compartment 120, a fan 320 arranged in the fan compartment 110 and a condenser. The energy storage device 400 is arranged in the energy storage compartment 130, and is configured to store the electric energy generated by the photovoltaic assembly 200 and supply electric energy to the air conditioning system. The control module 500 is arranged in the controller compartment 140, and is electrically connected to the photovoltaic assembly 200, the air conditioning system and the energy storage device 400, respectively.
[0063] The photovoltaic module 200 is used to absorb solar energy and convert it into electrical energy in a lighted environment, which can be directly supplied to various electrical units in the light storage air conditioner all-in-one machine or stored in the energy storage device 400. The energy storage device 400 can be used to store the electrical energy generated by the photovoltaic module 200, and supply power to the air conditioning system when the photovoltaic module 200 is insufficient (such as overcast, night). The cooperation of the two can make full use of solar energy, reduce energy costs, solve the problem of discontinuous power supply of the photovoltaic module 200 through the energy storage device 400, and ensure continuous power supply of the air conditioning system; It can also reduce the dependence on the power grid and achieve efficient and stable energy supply. Not only clean energy utilization is realized, but also energy consumption and operating cost is reduced.
[0064] The embodiment proposes an integrated design of a light storage air conditioner all-in-one machine, which integrates the photovoltaic module 200, the outdoor unit structure (compressor 310 and fan 320, etc.) in the air conditioning system, the energy storage device 400 and the control module 500 on the cabinet 100 or in each compartment inside the cabinet 100. The relative positions of each module are fixed and do not need to be temporarily determined according to the installation environment during installation. The installation cost is reduced, and the wiring between the photovoltaic module 200, the outdoor unit structure (compressor 310 and fan 320, etc.) in the air conditioning system, the energy storage device 400 and the control module 500 can be installed and wired inside the all-in-one machine. The wiring is short, which can effectively reduce the line loss, maximize the use of the electrical energy of the photovoltaic module 200 and the energy storage device 400, and reduce various connection interfaces between the structures during design.
[0065] In some embodiments, as shown in Figures 1-4 The photovoltaic module 200 is arranged on the cabinet 100 through the support 600. The support 600 provides a stable mounting structure for the photovoltaic module 200, which can be firmly fixed on the cabinet 100 to ensure that the photovoltaic module 200 remains stable under various environmental conditions (such as wind pressure, rain and snow). The support 600 can adjust the angle of the photovoltaic module 200 according to the geographical location and light conditions to maximize the reception of solar radiation and improve the photoelectric conversion efficiency. For example, the support 600 can be designed as a fixed or adjustable structure. The photovoltaic module 200 and the cabinet 100 form a certain spacing through the support 600, which helps air circulation and reduces the heat generated by the photovoltaic module 200 during operation, thereby improving the power generation efficiency. The support 600 sets the photovoltaic module 200 above the cabinet 100, which can utilize the space above the cabinet 100 without occupying additional installation space, and is suitable for integrated design of the light storage air conditioner all-in-one machine.
[0066] In some embodiments, the photovoltaic assembly 200 is arranged on the outer surface of the cabinet 100, and in particular, can be laid on the surface of the cabinet 100. Directly laying the photovoltaic assembly 200 on the outer surface of the cabinet 100 makes full use of the available space on the surface of the cabinet 100, avoids additional photovoltaic mounting structures or occupying additional installation sites, and is particularly suitable for integrated equipment, achieving compact design of the equipment structure. The photovoltaic assembly 200 laid on the surface of the cabinet 100 can be integrated with the photovoltaic assembly 200 at the factory, without the need for separate installation on site, simplifying the installation process and reducing construction difficulty and labor costs. The photovoltaic assembly 200 is laid flat on the surface of the cabinet 100, which is more visually appealing, with a coordinated and unified overall structure, suitable for home or commercial scenarios. Specifically, the photovoltaic assembly 200 can be directly laid on the top and outer facade of the cabinet 100, for example, the front surface, side surface, or top of the cabinet 100 can be designed as the power generation area of the photovoltaic assembly 200. The surface of the cabinet 100 can be flattened according to the laying requirements of the photovoltaic assembly 200 to ensure that the photovoltaic assembly 200 is firmly attached to the cabinet 100 and has waterproof and dustproof properties.
[0067] In some embodiments, as shown in Figure 5 and 6 , the photovoltaic assembly 200 and the cabinet 100 jointly enclose the fan compartment 110, the compressor compartment 120, the energy storage compartment 130, and the controller compartment 140, which can be understood as the photovoltaic assembly 200 and the cabinet 100 forming an integrated structure. The photovoltaic assembly 200 can be used as the outer shell of the cabinet 100, for example, in Figure 5 and Figure 6 , the photovoltaic assembly 200 and the cabinet 100 jointly enclose the fan compartment 110, the compressor compartment 120, the energy storage compartment 130, and the controller compartment 140. In this embodiment, the photovoltaic assembly 200 and the cabinet 100 are integrally formed, so that the photovoltaic assembly 200 is no longer an independent additional structure, but directly serves as a component part of the outer shell of the cabinet 100. This design simplifies the structure of the cabinet 100, reduces additional installation steps and support structures, not only achieves the external protection function of the equipment, but also improves the space utilization of the equipment, which is particularly suitable for home or commercial environments with strict requirements on equipment size. Integrating the photovoltaic assembly 200 as part of the cabinet 100 eliminates the need for traditional photovoltaic supports 600 and additional installation components, reducing the overall weight of the system, which is beneficial for transportation and installation of the equipment. The photovoltaic assembly 200 as the outer shell of the cabinet 100 can make the appearance of the equipment more neat and aesthetically pleasing, and the integrated design is more in line with the minimalist aesthetic needs of modern home or commercial scenarios.
[0068] Photovoltaic modules 200 typically possess excellent weather resistance and impact resistance. Using them as the outer casing of the enclosure 100 effectively protects the internal components—wind turbine hopper 110, compressor hopper 120, energy storage hopper 130, and controller hopper 140—from external environmental influences. In outdoor environments, photovoltaic modules 200 also offer waterproof and dustproof capabilities, further enhancing the equipment's reliability and durability. Integrating the photovoltaic modules 200 with the enclosure 100 to form the equipment's outer shell structure not only achieves the dual functions of photovoltaic power generation and equipment protection but also improves system integration, aesthetics, and space utilization, simplifying installation steps. This design is suitable for integrated photovoltaic-storage-air conditioning systems with high integration and high efficiency requirements.
[0069] In some implementations, such as Figures 1-5 As shown, the fan compartment 110 is located on one side of the horizontal direction, while the compressor compartment 120, the energy storage compartment 130, and the controller compartment 140 are located on the other side of the horizontal direction, with the compressor compartment 120 and the controller compartment 140 adjacent to the fan compartment 110. This layout rationally distinguishes the various functional areas, facilitating independent operation of each module, improving system stability and reliability, and allowing technicians to quickly locate problems based on the functions of different compartments, thus improving maintenance efficiency. Since the compressor 310 and control module 500 generate a large amount of heat during operation, the adjacent arrangement of the fan compartment 110 with the compressor compartment 120 and controller compartment 140 allows for some heat dissipation from the fan compartment 110, preventing overheating of the compressor 310 and control module 500 and extending the equipment's service life.
[0070] Furthermore, placing the wind turbine compartment 110 on one side and the compressor compartment 120, energy storage compartment 130, and controller compartment 140 on the other side helps to achieve a more balanced weight distribution for the entire equipment, improving its structural stability. During transportation and installation, this balanced weight distribution facilitates stable placement and fixation of the equipment, reducing the difficulty of transportation and installation.
[0071] In summary, this design achieves multiple advantages, such as system functional zoning, improved heat dissipation efficiency, balanced weight distribution, and maximized space utilization, by rationally distributing the fan compartment 110, compressor compartment 120, energy storage compartment 130, and controller compartment 140 in different areas of the chassis 100. It provides a more optimized structural layout for the photovoltaic-storage-air conditioning integrated unit.
[0072] In some implementations, such as Figure 7As shown, the control module 500 includes a control circuit 510, which includes a DC bus 511, a first DC / DC converter 512, a second DC / DC converter 513, and a first AC / DC converter 514. The DC bus 511 is electrically connected to the photovoltaic module 200 through the first DC / DC converter 512, and is electrically connected to the energy storage device 400 through the second DC / DC converter 513. The compressor 310 is electrically connected to the compressor 310 through the first AC / DC converter 514. The second DC / DC converter 513 is a bidirectional converter.
[0073] The DC bus 511 serves as the core channel for electric energy transmission, realizing centralized transmission and management of electric energy among the photovoltaic module 200, the energy storage device 400, and the air conditioning system, ensuring efficient flow of electric energy among the modules, reducing voltage fluctuations and losses in energy transmission, and improving the overall energy efficiency and stability of the system.
[0074] The first DC / DC converter 512 can convert unstable DC power output by the photovoltaic module 200 into stable DC power and transmit it to the DC bus 511 for use by the energy storage device 400 or the air conditioning system, realizing matching of the photovoltaic module 200 voltage and the DC bus 511 voltage and improving the utilization rate of photovoltaic electric energy.
[0075] The second DC / DC converter 513 is a bidirectional converter used to realize bidirectional transmission of electric energy between the energy storage device 400 and the DC bus 511. When photovoltaic electric energy is sufficient, the photovoltaic module 200 charges the energy storage device 400 through the DC bus 511. When photovoltaic electric energy is insufficient or the electrical load increases, the energy storage device 400 releases electric energy to the DC bus 511 to provide power supplement for the air conditioning system. The design of the bidirectional converter enables the system to flexibly adjust the flow direction of electric energy, optimizing the utilization efficiency of photovoltaic electric energy and energy storage electric energy.
[0076] The first AC / DC converter 514 is used to convert DC power output by the DC bus 511 into AC power to supply the compressor 310 for operation, meeting the AC power supply requirements of the compressor 310 operation, realizing efficient electric energy conversion from DC to AC, and ensuring stable operation of the air conditioning system.
[0077] The various converters in the control circuit 510 of the above embodiment work in cooperation with the DC bus 511 to achieve the management of the flow of electrical energy between the photovoltaic module 200, the energy storage device 400 and the air conditioning system by precisely controlling the voltage and current. The control module 500 can dynamically adjust the distribution of electrical energy according to the real-time photovoltaic power generation, the energy storage capacity and the load demand of the air conditioning system to ensure stable and efficient operation of the system. For example, when the sunlight is sufficient during the day, the photovoltaic module 200 can provide electrical energy to the DC bus 511 through the first DC / DC converter 512 to preferentially supply the air conditioning system, and the excess electrical energy is used to charge the energy storage device 400 for subsequent use. For another example, at night or when the sunlight is insufficient, the energy storage device 400 releases electrical energy through the second DC / DC converter 513 to supply the DC bus 511 to ensure the continuous and stable operation of the air conditioning system.
[0078] The present embodiment introduces the DC bus 511 and various converters to construct an efficient and intelligent electrical energy management system, which can realize the seamless cooperation between the photovoltaic module 200, the energy storage device 400 and the air conditioning system, and provides a stable and efficient energy solution for the photovoltaic energy storage air conditioner all-in-one machine.
[0079] On the basis of the above embodiment, as shown in Figure 4 The DC terminal 515 is located on the wall surface of the controller compartment 140 of the cabinet 100, which serves as the electrical interface between the photovoltaic module 200 and the control module 500 to simplify the wiring operation of the photovoltaic module 200. Through the standardized design of the DC terminal 515, the photovoltaic module 200 can be directly electrically connected to the cabinet 100 to improve the convenience and reliability of wiring. The DC terminal 515 can adopt the industry standard connector design, without complex wiring and additional connection equipment, which facilitates the quick access of the photovoltaic module 200, reduces the installation complexity, and ensures the stability of the electrical connection during long-term use to reduce the contact resistance and energy loss. The DC terminal 515 is connected to the DC bus 511 in the control module 500 to form a compact electrical energy transmission channel, which further shortens the wiring length and reduces the energy loss. The integrated design of the DC terminal 515 and the cabinet 100 reduces the number of external interfaces, making the photovoltaic energy storage air conditioner all-in-one machine more compact and beautiful. The DC terminal 515 can also achieve the "plug and play" effect, and the user only needs to connect the photovoltaic module 200 to the DC terminal 515 on the cabinet 100 during installation to complete the access of photovoltaic electrical energy, effectively reducing the installation cost and technical threshold.
[0080] On the basis of the above-mentioned embodiments, as shown in Figure 7 The control circuit 510 further includes a second AC / DC converter 516. The cabinet 100 is provided with an AC terminal 517 on the wall surface of the controller compartment 140. The DC bus 511 is electrically connected to the AC terminal 517 through the second AC / DC converter 516. The AC terminal 517 is configured to be electrically connected to an external power grid. The second AC / DC converter 516 is a bidirectional converter.
[0081] The second AC / DC converter 516 can realize bidirectional conversion between AC and DC, thereby realizing energy interconnection between the photovoltaic system, the energy storage device 400, and the external power grid. When the external power grid supplies power, the second AC / DC converter 516 can convert AC power from the external power grid into DC power to supply power to the air conditioning system and / or the energy storage device 400 through the DC bus 511. When the photovoltaic module 200 generates excess power, the second AC / DC converter 516 can convert DC power into AC power to be fed back to the power grid through the AC terminal 517, thereby realizing grid-connected power generation.
[0082] As shown in Figure 4 and 5 The AC terminal 517 is located on the wall surface of the controller compartment 140 and serves as an interface between the cabinet 100 and the external power grid, thereby simplifying the connection design with the power grid. The AC terminal 517 is electrically connected to the DC bus 511 through the second AC / DC converter 516, thereby realizing efficient transmission of internal energy of the cabinet 100 and the external power grid. When the photovoltaic module 200 outputs insufficient power or the energy storage device 400 has low power, the system can obtain power from the external power grid to ensure continuous power supply of the air conditioning system. When the photovoltaic module 200 and the energy storage device 400 generate power exceeding the system demand, the excess power can be fed back to the external power grid, thereby improving energy utilization and reducing power consumption.
[0083] The AC terminal 517 is designed to be integrated with the wall surface of the controller compartment 140 of the cabinet 100, thereby enabling the photovoltaic energy storage air conditioner all-in-one machine to be conveniently connected to the external power grid and realizing grid-connected or independent operation of the system. Through bidirectional control of the second AC / DC converter 516, flexible switching between the system and the external power grid is realized, thereby improving the adaptability and stability of the system.
[0084] The AC terminal 517 provided on the wall surface of the controller compartment 140 reduces external wiring and connection difficulty and facilitates interfacing with the external power grid. Through standardized AC interface design, the convenience and universality of system installation are improved.
[0085] For example, during the daytime high light period, the photovoltaic module 200 generates electricity which can be directly supplied to the air conditioning system, and the remaining electricity is stored in the energy storage device 400. If there is excess electricity, it is converted into alternating current by the second AC / DC converter 516 and fed back to the external power grid. For example, during the nighttime low light period, the air conditioning system can be powered by the energy storage device 400. If the energy storage capacity is insufficient, alternating current can be obtained from the external power grid through the second AC / DC converter 516 to power the system. For example, users can feed excess electricity from the photovoltaic system back to the external power grid according to the electricity price policy to maximize their income.
[0086] As shown above, by providing the AC terminal 517 and the bidirectional second AC / DC converter 516, the photovoltaic energy storage air conditioner all-in-one machine realizes flexible exchange of electricity with the external power grid, further improving the power supply reliability, energy utilization rate and installation convenience of the system, and providing an efficient, intelligent and energy-saving solution for users.
[0087] In some embodiments, as shown in Figure 7 The control module 500 also includes a main controller which can be used as a drive controller for the air conditioning system and a controller for the control circuit, serving as the core control unit of the entire machine. The protection level of the controller compartment 140 can be designed to be sand-proof, waterproof and insect-proof, which is beneficial to prolong the service life of the entire machine. As shown in Figure 7 The first DC / DC converter 512, the second DC / DC converter 513, the first AC / DC converter 514 and the second AC / DC converter 516 in the control circuit 510 are all connected to the main controller 520 through communication, and the data collected by each module is transmitted to the main controller 520. The main controller 520 communicates with the indoor unit 330 to realize data transmission, and the data is transmitted to the mobile terminal 700 by the indoor unit 330 for display. Of course, the mobile terminal 700 can also issue setting instructions to set the energy storage device 400 to charge and discharge, turn on and off the air conditioning system, etc., to regulate the operation mode of the overall system. The communication connection relationship between the structures is shown by the dashed line in Figure 7 .
[0088] In some embodiments, as shown in Figure 7 The air conditioning system also includes an indoor unit 330, and the indoor unit 330 is provided with an evaporator. The indoor unit 330 is a key component of the air conditioning system, mainly responsible for cooling or heating the air. For example, the evaporator in the indoor unit 330 can absorb the heat of the indoor air through the evaporation process of the refrigerant. The evaporator is usually matched with the indoor air flow, and the cooled air is sent into the room by a fan to adjust the temperature and humidity of the indoor environment.
[0089] The application also provides a working method of the light storage air conditioner all-in-one machine, which is applied to the light storage air conditioner all-in-one machine provided in the foregoing embodiments of the application. The working method can be divided into two cases, which are respectively for the light storage air conditioner all-in-one machine connected with the external power grid in a normal working state and the light storage air conditioner all-in-one machine not connected with the external power grid in a normal working state.
[0090] As shown in Figure 8 for the light storage air conditioner all-in-one machine connected with the external power grid in a normal working state, the working method of the light storage air conditioner all-in-one machine comprises the following steps.

[0092] if the photovoltaic module 200 meets the power generation condition, the photovoltaic module 200 generates power to supply the air conditioning system, and the external power grid supplies power to the air conditioning system when the photovoltaic module 200 generates insufficient power;
[0093] if the photovoltaic module 200 does not meet the power generation condition, it is determined whether the power of the energy storage device 400 is sufficient, if the power of the energy storage device 400 is sufficient, the energy storage device 400 supplies power to the air conditioning system, and if the power of the energy storage device 400 is insufficient, the external power grid supplies power to the air conditioning system.
[0094] First, it is determined whether the photovoltaic module 200 can generate power under the current condition, which usually depends on the light intensity and the health state of the photovoltaic module 200. If the photovoltaic module 200 meets the power generation condition, the photovoltaic module 200 generates power by absorbing sunlight and directly supplies the generated power to the air conditioning system to drive the air conditioning system to work. If the photovoltaic module 200 generates insufficient power to meet the entire demand of the air conditioning system, the external power grid will automatically supply the air conditioning system with additional power to ensure the stable operation of the air conditioning system.
[0095] When the photovoltaic module 200 cannot meet the power generation condition, the system determines whether the power of the energy storage device 400 is sufficient. If the power in the energy storage device 400 is sufficient, the system obtains power from the energy storage device 400 to continue to supply power to the air conditioning system. If the power of the energy storage device 400 is insufficient to meet the demand, the system automatically switches to the external power supply mode to supply power through the external power grid to ensure the operation of the air conditioning system.
[0096] This working method can ensure that when the light conditions are suitable, the photovoltaic module 200 is used to power the air conditioning system first, when the photovoltaic module 200 cannot generate electricity, the energy storage device 400 will supply power as a backup power supply, and when the photovoltaic and energy storage power is insufficient, the external power grid will be the final power source. The intelligent and adaptive ability of the photovoltaic and energy storage air conditioner all-in-one machine is improved, which can automatically adjust the power supply mode according to different environmental conditions, realize the maximum energy utilization efficiency, and improve the stability and operation efficiency of the air conditioning system.
[0097] On the basis of the above embodiment, the working method further comprises: while the photovoltaic module 200 generates electricity to supply the air conditioning system, evaluating whether the energy storage device 400 needs to be charged; if the energy storage device 400 needs to be charged, charging the energy storage device 400 with the excess electricity of the photovoltaic module 200 other than that used to supply the air conditioning system; if the energy storage device 400 does not need to be charged, feeding the excess electricity of the photovoltaic module 200 other than that used to supply the air conditioning system to the external power grid. Specifically, while the photovoltaic module 200 generates electricity and supplies the air conditioning system, the system will evaluate in real time whether the energy storage device 400 is full of electricity and whether it needs to be further charged. This evaluation process can be based on the current electricity of the energy storage device 400 and the set electricity threshold to determine. If the energy storage device 400 needs to be charged due to insufficient electricity, the system will use the excess electricity (i.e. the part exceeding the demand of the air conditioning system) generated by the photovoltaic module 200 to charge the energy storage device 400, so that the energy storage device 400 can be charged by the photovoltaic module 200 during the day when the light is sufficient, so as to provide backup power for the energy storage device 400 at night or when the light is insufficient. If the energy storage device 400 is full of electricity or has enough electricity, the system will feed the excess electricity generated by the photovoltaic module 200 to the external power grid. This can effectively utilize the remaining electricity generated by solar power, avoid waste, and feed the electricity back to the external power grid, which may generate certain economic benefits or further power regulation.
[0098] That is, the present embodiment can realize that the photovoltaic module 200 is preferentially used for charging the air conditioning system and the energy storage device 400, and when the photovoltaic power generation is sufficient, the air conditioning system and the energy storage device 400 will be supplied with electricity first, and the remaining electricity can be distributed to the energy storage device 400 or the external power grid as needed, to ensure that the energy storage device 400 can be charged when needed, and at the same time, the electricity can be fed back to the external power grid when the electricity is excessive. This intelligent electricity management mode helps to improve the energy utilization efficiency, reduce power waste, and provide more flexibility and adaptive ability for system operation, thereby optimizing the overall performance of the photovoltaic and energy storage air conditioner all-in-one machine.
[0099] As Figure 9As shown, for the photovoltaic storage air conditioner all-in-one machine not connected with the external power grid in normal working state, the working method of the photovoltaic storage air conditioner all-in-one machine comprises:
[0100] judging whether the photovoltaic module 200 meets the power generation condition;
[0101] if the photovoltaic module 200 meets the power generation condition, the photovoltaic module 200 generates power to supply the air conditioning system, and the energy storage device 400 supplies power to the air conditioning system when the photovoltaic module 200 generates insufficient power;
[0102] if the photovoltaic module 200 does not meet the power generation condition, it is evaluated whether the energy storage device 400 has sufficient power, if the energy storage device 400 has sufficient power, the energy storage device 400 supplies power to the air conditioning system, and if the energy storage device 400 does not have sufficient power, the air conditioning system runs at limited power or stops.
[0103] It should be noted that the above-mentioned case of not being connected with the external power grid in normal working state can be that the photovoltaic storage air conditioner all-in-one machine is not connected with the external power grid, or the photovoltaic storage air conditioner all-in-one machine is connected with the external power grid, but the external power grid is not in normal working state.
[0104] In this embodiment, the system first judges whether the photovoltaic module 200 is in an effective power generation state. This usually depends on the light intensity, the ambient temperature and the working efficiency of the photovoltaic module 200 itself. If the photovoltaic module 200 receives sufficient light and can generate effective power, the power generation condition is met. When the power generation condition is met, the photovoltaic module 200 first supplies power to the air conditioning system to drive the air conditioner to run, and if the power generation amount of the photovoltaic module 200 is insufficient to fully meet the demand of the air conditioning system, the system automatically switches to the energy storage device 400 to supplement power, so as to ensure that the air conditioning system can continue to work normally.
[0105] If the photovoltaic module 200 cannot meet the power generation condition (for example, cannot generate power due to overcast or night), the system continues to evaluate the power of the energy storage device 400, if the energy storage device 400 has sufficient power, the energy storage device 400 will provide power to the air conditioning system to ensure the normal operation of the air conditioner; if the energy storage device 400 does not have sufficient power, the system will take the following measures:
[0106] air conditioning system runs at limited power - if the air conditioning system is allowed to run at low power, the system can limit the power output of the air conditioner to run at a lower energy consumption.
[0107] stop - if the energy storage device 400 has very low power and cannot support the operation of the air conditioning system, the system will automatically stop the air conditioner to run to save the remaining power and avoid the complete depletion of the energy storage device 400.
[0108] In summary, the working method of the present embodiment can realize the priority use of photovoltaic power generation. The system first attempts to use the photovoltaic assembly 200 to generate electricity and supply power to the air conditioning system. When the photovoltaic power generation is insufficient, the energy storage device 400 provides supplemental power to ensure the continuous operation of the air conditioner. When the power demand cannot be met, the system adopts the strategy of limiting power or shutting down to ensure that the energy storage device 400 is not excessively discharged. This method can ensure that even without connecting to an external power grid, the photovoltaic storage air conditioner integrated machine can still effectively manage the power supply, ensure the operation of the air conditioning system under limited power resources, and avoid excessive discharge of the energy storage device 400.
[0109] On the basis of the above-mentioned embodiments, the working method further comprises: while the photovoltaic assembly 200 generates electricity to supply the air conditioning system, evaluating whether the energy storage device 400 needs to be charged; if the energy storage device 400 needs to be charged, charging the energy storage device 400 with the excess power of the photovoltaic assembly 200 other than the power supplied to the air conditioning system; if the energy storage device 400 does not need to be charged, limiting the power of the photovoltaic assembly 200.
[0110] In this embodiment, when the photovoltaic assembly 200 generates electricity and supplies power to the air conditioning system, the system will evaluate the power state of the energy storage device 400 in real time to determine whether it needs to be charged. By monitoring the remaining power of the energy storage device 400, it is determined whether it is below the preset charging threshold. If the energy storage device 400 is insufficient, the system will use the excess power generated by the photovoltaic assembly 200 (i.e. the excess power of the photovoltaic assembly 200 other than the power supplied to the air conditioning system) to charge the energy storage device 400, so that the energy storage device 400 can maintain sufficient power to provide backup power when the photovoltaic assembly 200 generates insufficient power in the future. If the energy storage device 400 is already fully charged and does not need to be charged, the system will use the power generated by the photovoltaic assembly 200 to supply the air conditioning system, and the output of the photovoltaic assembly 200 will be limited in power. Through the limited power operation, the system can prevent unnecessary power loss caused by excess power generation of the photovoltaic assembly 200, and at the same time ensure that the air conditioning system and the energy storage device 400 are reasonably distributed. This working method can improve the power utilization rate, ensure that the energy storage device 400 is in good charging condition, and at the same time avoid waste caused by excess power of the photovoltaic assembly 200, optimizing the power management among the photovoltaic assembly 200, the energy storage device 400 and the air conditioning system.
[0111] On the basis of the above-mentioned embodiments, the working method further comprises: in the process of supplementing power to the air conditioning system by the energy storage device 400 when the photovoltaic assembly 200 generates insufficient power, simultaneously evaluating whether the power of the energy storage device 400 is sufficient, if the power of the energy storage device 400 is sufficient, supplying power to the air conditioning system by the energy storage device 400, if the power of the energy storage device 400 is insufficient, limiting the power of the air conditioning system or shutting it down.
[0112] In the present embodiment, when the photovoltaic module 200 generates insufficient electricity to meet the air conditioning system demand, the system automatically switches to the power provided by the energy storage device 400, at this time, the energy storage device 400 as a power source, to ensure the continuous operation of the air conditioning system. In the process of the energy storage device 400 supplementing power to the air conditioning system, the system will monitor the power of the energy storage device 400 in real time, by continuously evaluating the power of the energy storage device 400, to determine whether it is sufficient to continue to provide power to the air conditioning system. If the power of the energy storage device 400 is sufficient, the system will continue to provide power to the air conditioning system from the energy storage device 400, to ensure the normal operation of the air conditioning system. If the power of the energy storage device 400 is insufficient to support the operation of the air conditioning system, the system will take measures to limit power or shut down.
[0113] Specifically, if the minimum operating demand of the air conditioning system can still be met by the power provided by the energy storage device 400, the system will limit the power output of the air conditioning system, thereby saving the power of the energy storage device 400 and prolonging its use time. If the power of the energy storage device 400 is too low to meet the minimum operating requirements of the air conditioning system, the system will automatically shut down to protect the energy storage device 400 from over-discharge.
[0114] In the above embodiment, when the photovoltaic module 200 generates insufficient electricity, the energy storage device 400 will provide power, and the system will evaluate the power state of the energy storage device 400 in real time. If the energy storage power is sufficient, continue to supply power; if the energy storage power is insufficient, the system will take power limiting or shutdown strategy to ensure the sustainable operation of the system. Through the intelligent control strategy, it is ensured that the energy storage device 400 will not be over-discharged, and at the same time the air conditioning system can run through power limiting or shutdown to ensure its stable operation for a long time under the condition of insufficient power. The intelligent level of the photovoltaic storage air conditioning system is improved, making the use of electricity more efficient and reasonable, and being able to flexibly adjust the working state of the air conditioning system under the condition of changing power supply, protect the energy storage device 400 and prolong the service life of the system.
