Solar photovoltaic power generation is an important way of solar energy utilization. Solar energy is a clean energy and will not cause pollution, so the photovoltaic power generation has been developed rapidly. An air conditioner is a heat exchange device, including an indoor unit, which is installed indoors and sends heat or cold produced by the indoor system of the air conditioner to the indoor through a fan, so as to achieve the purpose of adjusting the indoor temperature. During the operation of the air conditioner, a large amount of electric energy is consumed. In order to reduce the dependence on non-renewable energy, photovoltaic power generation can be used to supply power for the operation of the air conditioner.

[0003] A large amount of heat is generated when the energy storage battery is charged and discharged. High temperature will affect the performance and service life of the battery. When the light storage air conditioner cools in summer, the heat generated by the operation of the air conditioner outdoor unit and the high temperature caused by the sun's radiation greatly affect the temperature of the energy storage battery.

[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0037] As shown in Figures 1-5 The main structure of the light storage air conditioner all-in-one machine disclosed by the embodiments of the present application includes a shell 100, an air conditioning device, and an energy storage device. The air conditioning device includes a compressor 310, a four-way valve 320, a first heat exchanger 330, a throttling device 340, and a fan 350. The shell 100 is formed with a fan compartment 110, a compressor compartment 120, and an energy storage compartment 130. The fan 350 and the first heat exchanger 330 are located in the fan compartment 110. The compressor 310 and the four-way valve 320 are located in the compressor compartment 120. The energy storage device is located in the energy storage compartment 130. The energy storage device is configured to provide electrical energy to the air conditioning device. The D port of the four-way valve 320 is in communication with the exhaust port of the compressor 310 through an exhaust pipe 360. The E port of the four-way valve 320 is connected with a first refrigerant inlet and outlet pipe 500. The S port of the four-way valve 320 is in communication with the gas return port of the compressor 310 through a gas return pipe 370. The C port of the four-way valve 320 is in communication with the first heat exchanger 330 through a first heat exchanger pipe 380. One end of the throttling device 340 is in communication with the first heat exchanger 330, and the other end is connected with a second refrigerant inlet and outlet pipe 600. The first refrigerant inlet and outlet pipe 500 penetrates the energy storage compartment 130.

[0038] In the above embodiment, the first refrigerant inlet and outlet pipe 500 and the second refrigerant inlet and outlet pipe 600 are used to connect the air conditioning device with the indoor unit 400 to form a complete refrigerant circulation system. The four-way valve 320 is used to adjust the connection mode of each pipe in the air conditioning device to realize the switching of the refrigeration and heating functions of the air conditioning device.

[0039] In hot summer, when the air conditioning device is refrigerating, the flow direction of the refrigerant in the first refrigerant inlet and outlet pipe 500 is from the indoor unit 400 to the light storage air conditioner all-in-one machine. The refrigerant flowing in the first refrigerant inlet and outlet pipe 500 is low-temperature and low-pressure steam. The first refrigerant inlet and outlet pipe 500 passes through the energy storage compartment 130, and the low-temperature refrigerant can cool the surrounding air to cool the energy storage compartment 130, effectively reducing the temperature in the energy storage compartment 130, avoiding the risk of overheating of the energy storage device by natural cooling, and helping to prolong the service life of the energy storage device and maintain its good performance. Moreover, the temperature of the refrigerant in the first refrigerant inlet and outlet pipe 500 can be increased to a certain extent after heat exchange in the energy storage compartment 130, and the suction temperature of the compressor 310 can be significantly improved when the refrigerant returns to the light storage air conditioner all-in-one machine and enters the compressor 310.

[0040] In cold winter, when the air conditioning device heats, the flow direction of the refrigerant in the first refrigerant inlet and outlet pipe 500 is from the light storage air conditioner all-in-one machine to the indoor unit 400, and the refrigerant flowing in the first refrigerant inlet and outlet pipe 500 is high-temperature and high-pressure steam. The first refrigerant inlet and outlet pipe 500 passes through the energy storage bin 130, and the high-temperature refrigerant can warm the surrounding air to warm the energy storage bin 130, effectively improve the temperature in the energy storage bin 130, prevent the temperature of the energy storage device from being too low to achieve the optimal working state, and even cause the performance of the energy storage device to decline or stop working, and maintain its good performance. And the temperature of the high-temperature refrigerant in the first refrigerant inlet and outlet pipe 500 can be reduced to a certain extent after heat exchange in the energy storage bin 130, and when it enters the heat exchanger of the indoor unit 400, it can significantly reduce the working load of the heat exchanger of the indoor unit 400.

[0041] In summary, through the refrigerant flow characteristics of the first refrigerant inlet and outlet pipe 500, the heat dissipation and heating functions of the energy storage bin 130 are realized, without the need for additional active cooling or heating equipment, reducing system complexity and energy consumption. In summer, it can avoid overheating of the energy storage device, and in winter, it can prevent the energy storage device from being too cold, ensuring the stable operation of the energy storage device in high-temperature and low-temperature environments and prolonging the service life. By utilizing the temperature characteristics of the refrigerant in the first refrigerant inlet and outlet pipe 500 in different seasons, natural heat exchange is performed on the energy storage bin 130, ensuring the reliability of the energy storage device under different environmental temperatures, while optimizing the operating state of the compressor 310 and the heat exchanger of the indoor unit 400, and improving the overall energy efficiency of the air conditioning system.

[0042] In some embodiments, the first refrigerant inlet and outlet pipe 500 is arranged in a serpentine shape in the energy storage bin 130, thereby further improving the heat exchange efficiency of the energy storage bin 130 and achieving more effective temperature management of the energy storage device.

[0043] Specifically, the first refrigerant inlet and outlet pipe 500 is arranged in a serpentine path in the energy storage bin 130, which prolongs its path and forms a larger contact area with the internal air of the energy storage bin 130 or the surface of the surrounding energy storage device, increasing the heat exchange time and area. The serpentine arranged refrigerant pipe can uniformly cover the relevant parts in the energy storage bin 130, ensuring that the temperature distribution inside the energy storage bin 130 is more uniform, avoiding local overheating or overcooling, and uniform temperature distribution helps to keep the energy storage device within an appropriate operating temperature range, reduces performance fluctuations caused by temperature differences, and improves the charging and discharging efficiency and life of the energy storage device. The structure of the serpentine refrigerant pipe is simple and easy to implement, without the need for a complex control system, and is convenient to install and maintain, with higher overall reliability. By introducing a serpentine refrigerant pipe layout in the energy storage bin 130, this embodiment further optimizes the thermal management capability of the light storage air conditioner all-in-one machine, enabling the device to adapt to more diverse working conditions while maintaining high efficiency and stable operation, further improving user experience and system competitiveness.

[0044] In some embodiments, as shown in Figure 2 and 7 The light storage air conditioner all-in-one machine has a cooling mode, in which the D port of the four-way valve 320 communicates with the C port, and the E port communicates with the S port. Through this connection mode, the circulation flow of the refrigerant can be realized, so as to complete the cooling function.

[0045] The working principle of the cooling process is as follows: the refrigerant is compressed in the compressor 310 to form high-temperature and high-pressure steam, enters the D port of the four-way valve 320 through the exhaust pipe 360, the D port of the four-way valve 320 communicates with the C port, the high-temperature and high-pressure refrigerant gas enters the first heat exchanger pipe 380 through the C port of the four-way valve 320, and flows to the first heat exchanger 330 for heat exchange. The refrigerant becomes a constant-temperature and high-pressure liquid after being cooled and heat-released in the first heat exchanger 330, then enters the throttling device 340, and becomes a low-temperature and low-pressure liquid after being throttled by the throttling device 340, then enters the second refrigerant inlet and outlet pipe 600, flows out of the light storage air conditioner all-in-one machine through the second refrigerant inlet and outlet pipe 600, flows into the second heat exchanger 410 in the indoor unit 400, and becomes a low-temperature and low-pressure steam refrigerant after being evaporated and heat-absorbed in the second heat exchanger 410. Then it leaves the indoor unit 400 through the first refrigerant inlet and outlet pipe 500 and enters the E port of the four-way valve 320 in the light storage air conditioner all-in-one machine. In this process, it flows through the energy storage bin 130 to complete heat exchange with the energy storage bin 130. The E port of the four-way valve 320 communicates with the S port, the low-temperature and low-pressure steam refrigerant enters the first heat exchanger pipe 380 through the S port of the four-way valve 320, and flows to the first heat exchanger 330 for heat exchange. After entering the gas return pipe 370, it reenters the compressor 310 to complete compression and the next cycle.

[0046] Through the connection mode of the four-way valve 320, the flow direction of the refrigerant can be flexibly controlled to achieve rapid cooling. In the cooling mode, the first refrigerant inlet and outlet pipe 500 can be used to naturally cool the energy storage bin 130, effectively reducing the temperature of the energy storage device, prolonging its service life and improving its performance.

[0047] In some embodiments, as shown in Figure 3 and 8 The light storage air conditioner all-in-one machine has a heating mode, in which the D port of the four-way valve 320 communicates with the E port, and the C port communicates with the S port. Through this connection mode, the circulation flow of the refrigerant can be realized, so as to complete the heating function.

[0048] The working principle of the refrigeration process is as follows: the refrigerant is compressed in the compressor 310 to form high-temperature and high-pressure steam, enters the D port of the four-way valve 320 through the exhaust pipe 360, the D port of the four-way valve 320 is in communication with the E port, the high-temperature and high-pressure refrigerant gas enters the first refrigerant inlet and outlet pipe 500 through the E port of the four-way valve 320, flows out of the light storage air conditioner all-in-one machine through the first refrigerant inlet and outlet pipe 500, flows into the second heat exchanger 410 in the indoor unit 400, and the refrigerant flows through the energy storage bin 130 to complete heat exchange with the energy storage bin 130 in this process. The high-temperature and high-pressure steam refrigerant is cooled and released in the second heat exchanger 410 to become a constant-temperature and high-pressure liquid refrigerant, then leaves the indoor unit 400 through the second refrigerant inlet and outlet pipe 600 and enters the throttling device 340 in the light storage air conditioner all-in-one machine. The constant-temperature and high-pressure liquid refrigerant becomes low-temperature and low-pressure liquid refrigerant after being throttled by the throttling device 340, then enters the first heat exchanger 330, and the low-temperature and low-pressure liquid refrigerant becomes low-temperature and low-pressure steam refrigerant after being evaporated and absorbed by the first heat exchanger 330, then enters the C port of the four-way valve 320 through the first heat exchanger pipe 380, the C port of the four-way valve 320 is in communication with the S port, and the low-temperature and low-pressure steam refrigerant reenters the compressor 310 through the S port of the four-way valve 320 after entering the gas pipe 370 to complete compression and the next cycle.

[0049] Through the connection mode of the four-way valve 320, the flow direction of the refrigerant can be flexibly controlled to realize rapid heating. In the heating mode, the first refrigerant inlet and outlet pipe 500 can be used to naturally heat the energy storage bin 130, effectively improving the temperature of the energy storage device.

[0050] In some embodiments, the light storage air conditioner all-in-one machine further comprises a control module, the housing 100 further forms a controller bin 140, and the control module is located in the controller bin 140. The control module is electrically connected with the compressor 310, the energy storage device, the fan 350 and the four-way valve 320 respectively to realize efficient control and cooperative work of each component.

[0051] A controller compartment 140 is specially arranged in the shell 100 to accommodate the control module, ensuring that the control module is physically isolated from other functional components, reducing interference, and the controller compartment 140 can be designed with good heat dissipation to ensure that the control module maintains a stable operating temperature during long-term operation. The control module is located in the controller compartment 140 and is connected and communicates with other core components of the light storage air conditioner all-in-one machine through internal lines. For example, the control module can control the start, stop and working frequency of the compressor 310 according to temperature sensor, pressure sensor and other signal data, to optimize the refrigeration or heating effect of the air conditioning device; for another example, the control module can monitor the power state and temperature of the energy storage device, and issue corresponding instructions to control the operation mode of the light storage air conditioner all-in-one machine when the energy storage device is sufficient or insufficient, and start the heating or cooling function of the energy storage device when needed through the control module; for another example, the control module can be used to adjust the speed and running time of the fan 350 to achieve efficient heat exchange according to the air conditioning refrigeration or heating demand; for another example, the control module can be used to control the switching of the four-way valve 320 to realize the rapid conversion between air conditioning refrigeration mode and heating mode.

[0052] Through the unified management of the control module, the light storage air conditioner all-in-one machine can dynamically adjust the working state of each component according to the environmental temperature, user demand and energy storage device state, and improve the overall system operation efficiency. The centralized management and isolation design in the controller compartment 140 reduces electrical interference and ensures the stability of the system during long-term operation. In addition, the control module can also be used for integrated communication function to connect with external intelligent devices to realize remote control and real-time monitoring of the state.

[0053] In some embodiments, as shown in Figure 1 The light storage air conditioner all-in-one machine also includes a photovoltaic assembly 800 connected to the shell 100, which is electrically connected to the control module to realize efficient utilization and management of photovoltaic power generation. The photovoltaic assembly 800 is directly connected to the shell 100 of the light storage air conditioner all-in-one machine, which can provide renewable energy for the system. The specific installation position of the photovoltaic assembly 800 can be optimized according to the structure of the shell 100 and the lighting conditions to maximize the use of solar energy resources. The output end of the photovoltaic assembly 800 is connected to the control module through an electrical circuit. The circuit design may include an inverter, a DC-DC converter or an energy storage management unit to adjust the power output by the photovoltaic assembly 800 to meet the needs of the air conditioning device and the energy storage device.

[0054] The photovoltaic module 800 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. The energy storage device can be used to store the electrical energy generated by the photovoltaic module 800, and supply power to the air conditioning system when the photovoltaic module 800 is insufficient (such as overcast, night). The combination of the two can make full use of solar energy, reduce energy costs, solve the problem of discontinuous power supply of the photovoltaic module 800 through the energy storage device, and ensure continuous power supply of the air conditioning system; It can also reduce the dependence on the power grid, realize efficient and stable energy supply. Not only realize clean energy utilization, but also reduce energy consumption and operating cost.

[0055] Optionally, the photovoltaic module 800 converts solar energy into electrical energy and preferentially supplies the air conditioning device, reducing dependence on external power grids. When the electrical energy generated by the photovoltaic module 800 exceeds the demand of the air conditioning device, the control module can use the excess electrical energy to charge the energy storage device, or feed into the external power grid (if connected to the external power grid) according to the demand. The control module can also monitor the power generation state of the photovoltaic module 800 in real time, including output voltage, current and power and other parameters, dynamically adjust the working mode of the air conditioning device and the energy storage device according to the change of light intensity, and ensure efficient operation of the system. When the power generation of the photovoltaic module 800 is insufficient, the control module can intelligently adjust the operation mode of the air conditioning device (such as limited power operation) according to the power of the energy storage device, to ensure the stable operation of the equipment. When the photovoltaic module 800 generates excess electrical energy, the control module can distribute the electrical energy to the energy storage device to improve energy utilization efficiency. In the case of insufficient power generation of the photovoltaic module 800, the control module can start the energy storage device to supply power to the air conditioning device to maintain the normal operation of the air conditioner.

[0056] In summary, by directly supplying power through the photovoltaic module 800, the energy consumption of the external power grid can be reduced, and a green and environmentally friendly operation mode can be realized. The combination of photovoltaic power generation, energy storage and air conditioning load realizes efficient distribution and use of energy. It is more suitable for off-grid or power resource shortage areas, and at the same time improves the market competitiveness of the all-in-one machine. By integrating the photovoltaic module 800 on the shell 100 and electrically connecting with the control module, the light storage air conditioner all-in-one machine realizes efficient utilization and management of solar energy, making the system more energy-saving, environmentally friendly and intelligent during operation, effectively enhancing the independence and reliability of the light storage air conditioner all-in-one machine, and providing strong support for its application in various scenarios.

[0057] In some embodiments, as Figure 1As shown, the controller compartment 140 is located in the upper layer inside the housing 100, and the fan compartment 110, the compressor compartment 120 and the energy storage compartment 130 are located in the lower layer inside the housing 100. The integrated photovoltaic-storage-air conditioning unit proposed in this embodiment integrates the photovoltaic module 800, the outdoor unit structure of the air conditioning system (compressor 310, fan 350, four-way valve 320, etc.), the energy storage device, and the control module on the housing 100 or in various compartments inside the housing 100. The relative positions of each module are fixed, eliminating the need to temporarily determine the installation positions of the photovoltaic module 800, the air conditioning unit, and the energy storage device according to the installation environment during the installation process, thus reducing installation costs. Furthermore, the wiring between the photovoltaic module 800, the outdoor unit structure of the air conditioning system (compressor 310, four-way valve 320, and fan 350, etc.), the energy storage device, and the control module can be installed and wired internally within the integrated unit. The wiring is short, which can effectively reduce line loss, maximize the utilization of the electrical energy of the photovoltaic module 800 and the energy storage device, and reduce the number of connection interfaces between the various structures during the design phase.

[0058] Furthermore, this layout rationally distinguishes the various functional areas, which helps each module operate independently, improves the stability and reliability of the system, and allows technicians to quickly locate problems based on the functions of different compartments, thus improving maintenance efficiency. Since the control module generates a large amount of heat during operation, the fan compartment 110 and the controller compartment 140 are positioned vertically, allowing the fan compartment 110 to provide some cooling for the controller compartment 140, preventing overheating of the control module and extending the equipment's lifespan.

[0059] In some implementations, such as Figure 1 As shown, the fan compartment 110 and the energy storage compartment 130 are located on both sides of the compressor compartment 120. Since the compressor 310 also generates a lot of heat during operation, the fan compartment 110 and the compressor compartment 120 are arranged adjacent to each other, so that the fan compartment 110 can provide some heat dissipation to the compressor compartment 120, prevent the compressor 310 from overheating, and extend the service life of the equipment.

[0060] Furthermore, arranging the wind turbine compartment 110 and the energy storage compartment 130 on opposite sides of the compressor compartment 120 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 transportation and installation difficulties.

[0061] In summary, the design achieves multiple advantages such as system function partitioning, heat dissipation efficiency improvement, weight distribution balance, and space utilization maximization, etc. by reasonably distributing the fan compartment 110, the compressor compartment 120, the energy storage compartment 130, and the controller compartment 140 in different areas within the shell 100, thereby providing a more optimized structural layout for the light storage air conditioner all-in-one machine.

[0062] In some embodiments, as shown in FIG. 7, the light storage air conditioner all-in-one machine further includes a bypass pipeline 700, which is arranged in parallel with the part of the first refrigerant inlet and outlet pipe 500 that penetrates the energy storage compartment 130. Figure 5

[0063] The bypass pipeline 700 and the first refrigerant inlet and outlet pipe 500 are divided and converged outside the energy storage compartment 130, forming a parallel relationship. The first refrigerant inlet and outlet pipe 500 penetrates the energy storage compartment 130 for heat exchange with the energy storage device, while the bypass pipeline 700 bypasses the energy storage compartment 130 and directly provides a flow path. A control valve can be provided on the bypass pipeline 700 to adjust whether the refrigerant passes through the energy storage compartment 130 for heat exchange or to control the flow rate of the refrigerant passing through the energy storage compartment 130 according to the operating mode and demand.

[0064] In summer cooling mode, if the temperature of the energy storage device is appropriate or does not need additional cooling, the control valve on the bypass pipeline 700 can be opened to allow part or all of the refrigerant to bypass the energy storage compartment 130, thereby reducing unnecessary heat exchange and improving system efficiency. In winter heating mode, if the temperature of the energy storage device is high and does not need further heating, high-temperature refrigerant can also be directly delivered through the bypass pipeline 700 to avoid overheating the energy storage device. The bypass pipeline 700 provides a flexible refrigerant flow control method to optimize energy distribution under different operating conditions, reduce heat loss or unnecessary heat exchange processes, and improve the operating efficiency of the light storage air conditioner all-in-one machine. In addition, when the energy storage device does not need to adjust the temperature, the bypass pipeline 700 can reduce the flow resistance of the refrigerant in the energy storage compartment 130, thereby reducing the system operating load and prolonging the service life of the equipment. In summary, by arranging the bypass pipeline 700 in parallel with the first refrigerant inlet and outlet pipe 500 that penetrates the energy storage compartment 130, the light storage air conditioner all-in-one machine achieves flexible control of refrigerant flow direction, not only optimizing heat management efficiency, but also improving system stability and energy efficiency, providing important support for the intelligentization and multi-scenario adaptability of the light storage air conditioner all-in-one machine.

[0065] As shown in FIG. 7, the light storage air conditioner all-in-one machine further includes a bypass pipeline 700, which is arranged in parallel with the part of the first refrigerant inlet and outlet pipe 500 that penetrates the energy storage compartment 130. Figures 6-8 ​As shown, the embodiment of the present application also provides an air conditioning system, which comprises the indoor unit 400 and the light storage air conditioner all-in-one machine provided by the foregoing embodiments of the present application, wherein the indoor unit 400 comprises the second heat exchanger 410, and the first refrigerant inlet and outlet pipe 500 and the second refrigerant inlet and outlet pipe 600 are respectively communicated with two ends of the second heat exchanger 410. The indoor unit 400 is a key component of the air conditioning system, and is mainly responsible for cooling or heating air. For example, the second heat exchanger 410 in the indoor unit 400 can absorb the heat of indoor air through the evaporation process of refrigerant, and the second heat exchanger 410 is usually matched with indoor air flow, and the cooled air is sent into the indoor through a fan to adjust the temperature and humidity of the indoor environment.

[0066] The present 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 by the foregoing embodiments of the present 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.

[0067] As shown, Figure 9 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:

[0068] judging whether the photovoltaic module 800 meets the power generation condition;

[0069] If the photovoltaic module 800 meets the power generation condition, the photovoltaic module 800 generates power to supply the air conditioning device, and the external power grid supplies power to the air conditioning device when the photovoltaic module 800 generates insufficient power.

[0070] If the photovoltaic module 800 does not meet the power generation condition, it is judged whether the power of the energy storage device is sufficient, if the power of the energy storage device is sufficient, the energy storage device supplies power to the air conditioning device, and if the power of the energy storage device is insufficient, the external power grid supplies power to the air conditioning device.

[0071] Firstly, it is judged whether the photovoltaic module 800 can generate power under the current condition, which usually depends on the light intensity and the health state of the photovoltaic module 800. If the photovoltaic module 800 meets the power generation condition, the photovoltaic module 800 generates power by absorbing sunlight and directly supplies the generated power to the air conditioning device to drive the air conditioning device to work. If the photovoltaic module 800 generates insufficient power to meet the entire demand of the air conditioning device, the external power grid will automatically provide supplementary power to the air conditioning device to ensure the stable operation of the air conditioning device.

[0072] When the photovoltaic assembly 800 cannot meet the power generation conditions, the system will evaluate whether the power of the energy storage device is sufficient. If the power in the energy storage device is sufficient, the system will obtain power from the energy storage device to continue to provide power to the air conditioning device. If the power of the energy storage device is insufficient to meet the demand, the system will automatically switch to an external power grid power supply mode to supply power through the external power grid to ensure the operation of the air conditioning device.

[0073] This working method can ensure that when the light conditions are suitable, the photovoltaic assembly 800 first supplies power to the air conditioning device, when the photovoltaic assembly 800 cannot generate power, the energy storage device will serve as a backup power supply to supply power, and when the photovoltaic and energy storage power is insufficient, the external power grid will serve as the final power source. The intelligentization and self-adaptive ability of the photovoltaic-energy storage air conditioner all-in-one machine are 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 device.

[0074] On the basis of the above embodiment, the working method further comprises: while the photovoltaic assembly 800 generates power to supply the air conditioning device, evaluating whether the energy storage device needs to be charged; if the energy storage device needs to be charged, charging the energy storage device with the excess power of the photovoltaic assembly 800 other than that supplied to the air conditioning device; and if the energy storage device does not need to be charged, feeding the excess power of the photovoltaic assembly 800 other than that supplied to the air conditioning device to the external power grid. Specifically, while the photovoltaic assembly 800 generates power and supplies the air conditioning device, the system will evaluate in real time whether the power of the energy storage device is full or needs to be further charged. This evaluation process can be based on the current power of the energy storage device and the set power threshold to determine whether the energy storage device needs to be charged. If the power of the energy storage device is insufficient and needs to be charged, the system will use the excess power (i.e., the part exceeding the demand of the air conditioning device) generated by the photovoltaic assembly 800 to charge the energy storage device, so that the energy storage device can be charged by the photovoltaic assembly 800 during the day when the light is sufficient, so as to provide backup power for the energy storage device at night or when the light is insufficient. If the energy storage device is full or the power is sufficient, the system will feed the excess power generated by the photovoltaic assembly 800 to the external power grid, which can effectively utilize the remaining power generated by solar power, avoid waste, and feed the power back to the external power grid, which may generate certain economic benefits or further power regulation.

[0075] That is, the embodiment can realize that the photovoltaic module 800 is preferentially used for charging the air conditioning device and the energy storage device. When the photovoltaic power generation is sufficient, the air conditioning device and the energy storage device will first obtain power supply, and the power of the photovoltaic module 800 can be effectively managed. The remaining power is distributed to the energy storage device or the external power grid as needed, ensuring that the energy storage device can be charged when needed, and feeding back power to the external power grid when the power is excessive. This intelligent power management method helps to improve energy utilization efficiency, reduce power waste, and provide more flexibility and adaptive ability for system operation, thereby optimizing the overall performance of the photovoltaic storage air conditioner all-in-one machine.

[0076] As shown in Figure 10 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 includes:

[0077] determining whether the photovoltaic module 800 meets the power generation condition;

[0078] If the photovoltaic module 800 meets the power generation condition, the photovoltaic module 800 supplies power to the air conditioning device, and the energy storage device supplements power to the air conditioning device when the photovoltaic module 800 is insufficient;

[0079] If the photovoltaic module 800 does not meet the power generation condition, it is determined whether the energy storage device has sufficient power. If the energy storage device has sufficient power, the energy storage device supplies power to the air conditioning device. If the energy storage device does not have sufficient power, the air conditioning device operates at limited power or stops.

[0080] 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.

[0081] In the present embodiment, the system first determines whether the photovoltaic module 800 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 800 itself. If the photovoltaic module 800 receives sufficient light and can generate effective power, the power generation condition is met. When the power generation condition is met, the photovoltaic module 800 first supplies power to the air conditioning device to drive the air conditioner to operate. If the power generation amount of the photovoltaic module 800 is insufficient to completely meet the demand of the air conditioning device, the system will automatically switch to the energy storage device to supplement power, ensuring that the air conditioning device can continue to work normally.

[0082] If the photovoltaic module 800 cannot meet the power generation conditions (for example, cannot generate power due to overcast weather or at night), the system will continue to assess the power of the energy storage device. If the power of the energy storage device is sufficient, the energy storage device will provide power for the air conditioning device to ensure normal operation of the air conditioner. If the power of the energy storage device is insufficient, the system will take the following measures:

[0083] Limited power operation of the air conditioning device - if the air conditioning device is allowed to operate at low power, the system may limit the power output of the air conditioner to run at a lower energy consumption.

[0084] Shutdown - if the power of the energy storage device is extremely low and cannot support the operation of the air conditioning device, the system will automatically stop the operation of the air conditioner to save the remaining power and avoid the complete depletion of the energy storage device.

[0085] 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 module 800 to generate power and supply power to the air conditioning device. When the photovoltaic power generation is insufficient, the energy storage device provides supplementary 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 power of the energy storage device is not excessively consumed. This method can ensure that even without connecting to an external power grid, the photovoltaic and energy storage air conditioner integrated machine can still effectively manage the power supply, ensure the operation of the air conditioning device under limited power resources, and avoid excessive discharge of the energy storage device.

[0086] On the basis of the above-mentioned embodiments, the working method further comprises: while the photovoltaic module 800 generates power to supply the air conditioning device, assessing whether the energy storage device needs to be charged; if the energy storage device needs to be charged, charging the energy storage device with the excess power of the photovoltaic module 800 that is not supplied to the air conditioning device; and if the energy storage device does not need to be charged, limiting the power of the photovoltaic module 800.

[0087] In this embodiment, when the photovoltaic module 800 generates electricity and supplies power to the air conditioning unit, the system continuously assesses the power status of the energy storage device to determine whether charging is necessary. By monitoring the remaining power of the energy storage device, it determines whether it falls below a preset charging threshold. If the energy storage device's power is insufficient, the system uses the excess power generated by the photovoltaic module 800 (i.e., the remaining power beyond what the photovoltaic module 800 provides to the air conditioning unit) to charge the energy storage device. This ensures the energy storage device maintains sufficient power to provide backup power in case the photovoltaic module 800's power generation is insufficient in the future. If the energy storage device already has sufficient power and does not require charging, the system uses the photovoltaic module 800's power generation to supply the air conditioning unit, and the photovoltaic module 800's output is limited. This power-limiting operation prevents unnecessary power loss due to excessive power generation by the photovoltaic module 800, while ensuring the most reasonable power allocation between the air conditioning unit and the energy storage device. This method improves power utilization, ensures a good charging status for the energy storage device, avoids waste caused by excess power in the photovoltaic module 800, and optimizes power management among the photovoltaic module 800, the energy storage device, and the air conditioning unit.

[0088] Based on the above implementation method, the working method further includes: when the photovoltaic module 800 generates insufficient power, the energy storage device supplements the power supply to the air conditioning device, while simultaneously assessing whether the power of the energy storage device is sufficient. If the power of the energy storage device is sufficient, the energy storage device supplies power to the air conditioning device; if the power of the energy storage device is insufficient, the air conditioning device operates with limited power or shuts down.

[0089] In this embodiment, when the photovoltaic module's power generation is insufficient to meet the air conditioning unit's needs, the system automatically switches to power supply from the energy storage device. At this time, the energy storage device acts as the power source, ensuring the continuous operation of the air conditioning unit. During the process of the energy storage device replenishing power to the air conditioning unit, the system monitors the energy storage device's power level in real time. By continuously assessing the energy storage device's power level, it determines whether it is sufficient to continue providing power to the air conditioning unit. If the energy storage device has sufficient power, the system will continue to supply power to the air conditioning unit from the energy storage device to ensure its normal operation. If the energy storage device's power is insufficient to support the operation of the air conditioning unit, the system will take measures such as power limiting operation or shutdown.

[0090] Specifically, if the minimum operating requirements of the air conditioning unit can still be met by the power provided by the energy storage device, the system will limit the power output of the air conditioning unit, thereby saving the energy storage device's power and extending its usage time. If the energy storage device's power is too low to meet the minimum operating requirements of the air conditioning unit, the system will automatically shut down to protect the energy storage device from over-discharge.

[0091] In the above implementation, when the photovoltaic module 800 generates insufficient power, the energy storage device provides electricity, and the system continuously assesses the energy storage device's power status. If the stored energy is sufficient, power supply continues; if the stored energy is insufficient, the system adopts power limiting or shutdown strategies to ensure sustainable system operation. Through intelligent control strategies, the system ensures that the energy storage device is not over-discharged, while the air conditioning unit can maintain stable operation for extended periods by limiting power or shutting down when power is insufficient. This enhances the intelligence level of the photovoltaic-storage-air conditioning system, making electricity use more efficient and rational. It can flexibly adjust the operating status of the air conditioning unit under varying power supply conditions, protecting the energy storage device and extending the system's lifespan.
