Description

Technical Field

[0001] This application relates to the field of smart home technology, and in particular to a photovoltaic air conditioner power supply control method, device, photovoltaic air conditioner and storage medium. Background Technology

[0002] Against the backdrop of the global clean and low-carbon energy transition, photovoltaic air conditioning, with its advantages of "self-generation and self-consumption, green energy saving," has been widely used in commercial complexes, factories, residential communities, and other scenarios, making it an important choice for building energy upgrades. Its energy supply logic is as follows: solar energy is converted into electricity through rooftop and surrounding photovoltaic panels. When sunlight is sufficient, it can simultaneously power core components such as compressors and small loads such as electrical control and communication systems, achieving a match between photovoltaic energy and system demand and reducing dependence on the external power grid.

[0003] However, photovoltaic energy output is highly dependent on sunlight. Cloudy days, weak sunlight in the early morning or late evening, or shading can cause a sharp drop in power generation, making it difficult to cover the overall electricity demand of photovoltaic air conditioners. At this time, photovoltaic air conditioners are caught in an energy allocation dilemma: prioritizing power supply to core components will cause data interruptions and parameter loss due to insufficient power for small loads, affecting intelligent regulation; reserving power for small loads will lead to insufficient power for core components, a sharp drop in cooling / heating efficiency, or even shutdown. The imbalance in energy allocation has become a key bottleneck restricting the operational stability of photovoltaic air conditioners.

[0004] This imbalance not only affects the performance of photovoltaic air conditioners but also reduces the utilization rate of photovoltaic energy and exacerbates grid dependence. On the one hand, the imbalance in power distribution leads to the waste of electricity, which contradicts the original intention of "efficient use of clean energy." On the other hand, air conditioners need to rely more on external grid power, which increases grid pressure and weakens their advantage of reducing grid dependence, hindering the autonomous and low-carbon development of building energy systems. Summary of the Invention

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0028] like Figure 1 The diagram shown is a structural schematic of a photovoltaic air conditioning power supply control system provided in an embodiment of this application. The photovoltaic air conditioning power supply control system includes a photovoltaic air conditioner, a main photovoltaic panel, an auxiliary photovoltaic panel, and a mains power grid.

[0029] The aforementioned photovoltaic air conditioner is the core load device of the photovoltaic air conditioner power supply control system. Its air conditioner electrical box integrates various power devices, including but not limited to high-power devices such as compressors, as well as low-power but critical functional components such as electrical control modules and communication modules. Based on the photovoltaic air conditioner power supply control system, the rational allocation and efficient utilization of photovoltaic air conditioner power can be achieved, ensuring stable operation of the photovoltaic air conditioner under different lighting conditions.

[0030] The aforementioned main photovoltaic panels serve as the primary power source for the photovoltaic air conditioning power supply control system. They can be installed on the roof or around the photovoltaic air conditioning unit to provide power to the photovoltaic air conditioning system. Under specific conditions (such as when the light intensity is below a set threshold), they only provide power to high-power devices (such as the compressor) in the air conditioning electrical box of the photovoltaic air conditioning system.

[0031] The aforementioned auxiliary photovoltaic (PV) panels are rotatable and foldable small PV panels that serve as an auxiliary power source for the PV air conditioner power supply control system. They can be integrated into the outer casing of the PV air conditioner, providing structural support and shading; alternatively, they can be embedded in windows on the air conditioner's outer casing (such as the left, right, or front side), unfolding when needed to increase the sunlight reception area and improve power generation efficiency. When sunlight conditions are insufficient or the main PV panel's power generation capacity decreases, the auxiliary PV panels can quickly unfold and provide independent power to low-power critical components (such as the electrical control module and communication module) in the air conditioner's electrical box, ensuring the stable operation of these critical components and preventing data loss or malfunction of the PV air conditioner power supply control system due to power outages.

[0032] Furthermore, the photovoltaic (PV) air conditioning power supply control system can also include the mains power grid, which serves as a backup or supplementary power source. When PV energy (main PV panels and / or foldable small PV panels) cannot meet the needs of the PV air conditioning power supply control system (such as during consecutive cloudy or rainy days or at night), it can automatically switch to the mains power grid to ensure the continuous operation of the PV air conditioner. This method not only improves the flexibility of the PV air conditioning power supply control system but also further reduces its dependence on the external power grid.

[0033] By using the main photovoltaic panel to power the high-power devices in the photovoltaic air conditioner and the auxiliary photovoltaic panel to power the low-power devices, the main and auxiliary photovoltaic panels can be powered together, ensuring that the critical functions of the photovoltaic air conditioner are not interrupted. This fundamentally solves the problems of declining operating performance, low photovoltaic energy utilization, and strong dependence on the external power grid caused by energy imbalance in existing photovoltaic air conditioning systems.

[0034] like Figure 2 The diagram shown is a schematic representation of the implementation process of a photovoltaic air conditioner power supply control method provided in this application embodiment. This method is applied to an intelligent power management module and may specifically include the following steps: S201, obtain the current electrical performance parameters of the main photovoltaic panel and determine the first power device and the second power device in the photovoltaic air conditioner. The power consumption of the first power device is greater than that of the second power device.

[0035] In this embodiment, the current electrical performance parameters of the main photovoltaic panel are obtained through an intelligent power management module. This intelligent power management module can be a power supply control unit, possessing multiple functions such as data acquisition, analysis and judgment, and command output, enabling precise control of the power supply to the photovoltaic air conditioner based on the acquired information. The intelligent power management module may include a processor, voltage / current sensors, and switching circuits, used to monitor the photovoltaic system status in real time and execute power supply control strategies. The main photovoltaic panel can be various types and specifications of photovoltaic arrays (solar panels) laid on the roof or around the photovoltaic air conditioning unit, used to convert solar energy into electrical energy and power the photovoltaic air conditioner. Electrical performance parameters can be understood as performance parameters that measure the working status and power generation capacity of the main photovoltaic panel; this embodiment does not limit this definition.

[0036] The first and second power devices in the photovoltaic air conditioner are determined by an intelligent power management module, wherein the power consumption of the first power device is greater than that of the second power device. The photovoltaic air conditioner can be an air conditioning system that uses solar energy to generate electricity, converting light energy into electrical energy to power the air conditioner itself. The first power device can be a high-power component in the photovoltaic air conditioner, such as a compressor or fan motor. Taking the compressor as an example, the compressor is the core component for air conditioning cooling and heating, compressing and circulating air by compressing the refrigerant to regulate the indoor temperature. This process requires a large amount of electrical energy to operate, hence the compressor is a high-power component. The second power device can be a low-power but functionally critical component, such as an electronic control module, a communication module, or a display unit. The electronic control module is responsible for controlling the operation of various components of the photovoltaic air conditioner, the communication module is used to enable communication between the photovoltaic air conditioner and external devices (such as mobile apps, smart home systems, etc.), and the display unit is used to display information such as the air conditioner's operating status and temperature settings. Its power consumption is relatively small, but it plays a crucial role in the normal operation of the air conditioner; this application does not limit this aspect.

[0037] S202, if the electrical performance parameters meet the power supply control conditions, perform the following power supply control operation: control the main photovoltaic panel to supply power to the first power device, and control the auxiliary photovoltaic panel to supply power to the second power device.

[0038] In this embodiment, the electrical performance parameters obtained through the above steps, when meeting the power supply control conditions, can be used to execute a power supply control operation that controls the main photovoltaic panel to supply power to the first power device and the auxiliary photovoltaic panel to supply power to the second power device. The power supply control conditions can be the core standard for evaluating the power generation performance of the main photovoltaic panel, and can be set to specific parameters such as the voltage being lower than a certain percentage below the rated value for a duration exceeding a set threshold. The auxiliary photovoltaic panel can be an auxiliary power generation component integrated into the air conditioner casing (e.g., a foldable or nested design), serving both as a structural support component and supplying power to low-power critical components (such as the electrical control module and communication module) when the main photovoltaic panel's power generation is insufficient. Its unfolding degree can be dynamically adjusted according to sunlight and power demand. This embodiment does not limit this aspect.

[0039] Specifically, when the electrical performance parameters meet the power supply control conditions, the intelligent power management module will execute the following power supply control operations: It will control the main photovoltaic panel to supply power to the first power devices, meaning that the electrical energy generated by the main photovoltaic panel will be preferentially delivered to high-power devices such as the compressor and fan motor, ensuring they receive sufficient power for normal operation and thus guaranteeing the cooling and heating effects of the air conditioner. Simultaneously, it will control the auxiliary photovoltaic panel to supply power to the second power devices, providing independent power to low-power critical components such as the electronic control module, communication module, and display unit. This way, even if the main photovoltaic panel fails or its power supply capacity decreases, these critical components can continue to operate normally, avoiding data loss or loss of control of the photovoltaic air conditioner power supply system due to power outages.

[0040] Based on the above description of the technical solution provided in the embodiments of this application, the current electrical performance parameters of the main photovoltaic panel are obtained, and the first power device and the second power device in the photovoltaic air conditioner are determined. The power consumption of the first power device is greater than that of the second power device. When the electrical performance parameters meet the power supply control conditions, the following power supply control operation is performed: the main photovoltaic panel is controlled to supply power to the first power device, and the auxiliary photovoltaic panel is controlled to supply power to the second power device.

[0041] This allows the main and auxiliary photovoltaic panels to work together to supply power, ensuring that the key functions of the photovoltaic air conditioner are not interrupted. It fundamentally solves the problems of declining operating performance, low photovoltaic energy utilization, and strong dependence on the external power grid caused by the imbalance of energy distribution in existing photovoltaic air conditioning systems.

[0042] Based on this, such as Figure 3 The diagram shown illustrates the implementation flow of another photovoltaic air conditioning power supply control method provided in this application embodiment. This method is applied to an intelligent power management module and may specifically include the following steps: S301, obtain the current electrical performance parameters of the main photovoltaic panel.

[0043] In this embodiment, the current electrical performance parameters of the main photovoltaic panel are obtained. These electrical performance parameters can be understood as performance parameters that measure the working status and power generation capacity of the main photovoltaic panel, and are used to determine whether the main photovoltaic panel meets the power supply requirements of the core components (such as the compressor) of the photovoltaic air conditioner. The electrical performance parameters may include voltage and / or current, but this embodiment does not limit the specific parameters.

[0044] Specifically, the intelligent power management module can acquire data in real time from voltage and / or current sensors deployed at the output end of the main photovoltaic panel via wired or wireless means to obtain the current electrical performance parameters (voltage and / or current) of the main photovoltaic panel.

[0045] For example, the current voltage of the main photovoltaic panel (such as 100V, 120V, etc.) can be obtained from a voltage sensor deployed at the output end of the main photovoltaic panel via a wired connection, and used as an electrical performance parameter.

[0046] S302, obtain any power device in the photovoltaic air conditioner and determine the power consumption of the power device.

[0047] In this embodiment, any power device in a photovoltaic air conditioner is obtained. A power device can be understood as a component in a photovoltaic air conditioner that consumes electrical energy, including but not limited to compressors, fan motors, electronic control modules, and communication modules. For any power device in the obtained photovoltaic air conditioner, its power consumption can be determined to classify the power device. Power consumption can be understood as the rate at which the power device consumes electrical energy during operation (e.g., 1000W, 10W). This embodiment does not limit this.

[0048] S303, if the ratio between the power consumption of the power device and the total power consumption of the photovoltaic air conditioner is greater than a preset first value, the power device is determined as the first power device.

[0049] In this embodiment of the application, the power device can be identified as the first power device if the ratio between the power consumption of the power device and the total power consumption of the photovoltaic air conditioner is greater than a preset first value.

[0050] It should be noted that the aforementioned first preset value can be a pre-set threshold (such as 50% or 60%) used to distinguish high-power devices. The aforementioned total power consumption of the photovoltaic air conditioner refers to the total power consumption of all power devices in the photovoltaic air conditioner when operating at full load (such as 2000W). The aforementioned first power device can be the main power-consuming component in the photovoltaic air conditioner (such as compressor, fan motor, etc.), and this application embodiment does not limit this.

[0051] For example, if the preset first value is 60%, the power consumption of power device 1 (compressor) is 2800W, and the total power consumption of photovoltaic air conditioner is 4000W, the ratio between the power consumption of power device 1 and the total power consumption of photovoltaic air conditioner is 2800W÷4000W=70%, which is greater than the preset first value of 60%. Therefore, the compressor is the first power device.

[0052] S304, if the ratio between the power consumption of the power device and the total power consumption of the photovoltaic air conditioner is less than a preset second value, the power device is determined as the second power device, wherein the preset first value is greater than the preset second value, and the power consumption of the first power device is greater than the power consumption of the second power device.

[0053] In this embodiment of the application, when the ratio between the power consumption of the power device and the total power consumption of the photovoltaic air conditioner is less than a preset second value, the power device is determined to be the second power device, wherein the preset first value is greater than the preset second value, and the power consumption of the first power device is greater than the power consumption of the second power device.

[0054] It should be noted that the aforementioned preset second value can be a pre-set threshold (such as 10% or 15%) used to distinguish low-power devices. The aforementioned second power device can be a key component with relatively low power consumption in a photovoltaic air conditioner (such as an electronic control module, communication module, display unit, etc.), and this application embodiment does not limit this.

[0055] For example, if the preset second value is 10%, the power consumption of power device 2 (fan) is 300W, and the total power consumption of photovoltaic air conditioner is 4000W, the ratio between the power consumption of power device 2 and the total power consumption of photovoltaic air conditioner is 300W÷4000W=7.5%, which is less than the preset second value of 10%. Therefore, the fan is the second power device.

[0056] In addition, if the ratio between the power consumption of the power device and the total power consumption of the photovoltaic air conditioner is less than or equal to a preset first value and greater than or equal to a preset second value, the power device is determined as the first power device or the second power device according to the functional positioning or control method of the power device. The specific implementation process can be referred to in the following steps.

[0057] S305, when the electrical performance parameters meet the power supply control conditions, performs the following power supply control operation: controls the main photovoltaic panel to supply power to the first power device.

[0058] In this embodiment, when the electrical performance parameters meet the power supply control conditions, the intelligent power management module executes a power supply control operation to control the main photovoltaic panel to supply power to the first power device. The power supply control conditions can be a core standard for evaluating the power generation performance of the main photovoltaic panel, and can be set to specific parameters such as the voltage being lower than a certain percentage of the rated value for a duration exceeding a set threshold.

[0059] Specifically, the aforementioned electrical performance parameters may include voltage and / or current. The electrical performance parameters satisfying the power supply control conditions can be: the voltage being less than a preset voltage threshold for a preset first duration; and / or the current being less than a preset current threshold for a preset second duration. The preset voltage threshold may be a pre-set voltage value used to evaluate the power generation performance of the main photovoltaic panel (e.g., a preset voltage value of 200V, 10% of the rated voltage of the main photovoltaic panel); the preset first duration is a pre-set time parameter used to avoid false triggering due to instantaneous voltage fluctuations (e.g., 1 second, 2 seconds, etc.); the preset current threshold is a pre-set current value used to evaluate the power generation performance of the main photovoltaic panel (e.g., a preset current value of 20A, 10% of the rated current of the main photovoltaic panel); and the preset second duration is a pre-set time parameter used to avoid false triggering due to instantaneous current fluctuations (e.g., 1 second, 2 seconds, etc.).

[0060] S306, determine the current power consumption of the second power device and the current light intensity of the environment where the photovoltaic air conditioner is located.

[0061] In this embodiment of the application, for the second power device determined above, the current power consumption of the second power device can be determined by a power sensor, and the current light intensity of the environment where the photovoltaic air conditioner is located can be determined by a light sensor. Here, the current light intensity refers to the real-time light energy density of the environment where the photovoltaic air conditioner is located (e.g., 800 W / m²).

[0062] S307, determine the extent of the auxiliary photovoltaic panel's deployment based on the current power consumption of the second power device and the current light intensity.

[0063] In this embodiment, the extent of the auxiliary photovoltaic panel's deployment can be determined based on the current power consumption of the second power device and the current light intensity. The auxiliary photovoltaic panel can serve as part of the photovoltaic air conditioner's outer casing, providing structural support and shading, or it can be nested within the photovoltaic air conditioner's outer casing.

[0064] To determine the extent of the auxiliary photovoltaic panel's deployment based on the current power consumption of the second power device and the current light intensity, you can refer to... Figure 4 The method shown. (As shown) Figure 4 The diagram shown illustrates the implementation flow of a method for determining the unfolding extent of an auxiliary photovoltaic panel according to an embodiment of this application. The method may specifically include the following steps: S401, determine the target power consumption based on the current power consumption of the second power device and the preset redundancy threshold.

[0065] In this embodiment of the application, the preset redundancy threshold can be a percentage (such as 10%, 15%, etc.) set in advance to cope with uncertainties such as light intensity fluctuations and instantaneous power changes of the second power device.

[0066] Specifically, the current power consumption of the second power device and the preset redundancy threshold can be input into the target power consumption formula to calculate the target power consumption. The target power consumption calculation formula can be: ; in, For the target power consumption, To preset the redundancy threshold, This represents the current power consumption of the second power device.

[0067] For example, if the preset redundancy threshold is 10%, the current power consumption of the second power device is 1W, and the target power consumption is (1+10%)×1W=1.1W.

[0068] S402, obtain the power generation efficiency of the auxiliary photovoltaic panel, and determine the extent of deployment of the auxiliary photovoltaic panel based on the target power consumption, power generation efficiency and current light intensity.

[0069] In this embodiment, the power generation efficiency of the auxiliary photovoltaic panel can be obtained, and the deployment degree of the auxiliary photovoltaic panel can be determined based on the target power consumption, power generation efficiency, and current irradiance. The power generation efficiency is the ratio of received solar radiation energy converted into electrical energy by the auxiliary photovoltaic panel, reflecting its performance.

[0070] Specifically, the extent to which the auxiliary photovoltaic panels are deployed is determined based on the target power consumption, power generation efficiency, and current solar irradiance. This can be referenced from [reference needed]. Figure 5 The method shown. (As shown) Figure 5 The diagram shown illustrates the implementation flow of another method for determining the unfolding degree of an auxiliary photovoltaic panel provided in this application. This method may specifically include the following steps: S501: Input the target power consumption, power generation efficiency, and current light intensity into the unfolded area calculation formula to obtain the unfolded area of ​​the auxiliary photovoltaic panel.

[0071] In this embodiment of the application, the target power consumption, power generation efficiency, and current light intensity are input into the unfolded area calculation formula to obtain the unfolded area of ​​the auxiliary photovoltaic panel.

[0072] Specifically, the formula for calculating the unfolded area can be: S_pv_need=(P_pv_target×1000) / (E_light×η); Where S_pv_need is the unfolded area, P_pv_target is the target power consumption, E_light is the current light intensity, and η is the power generation efficiency.

[0073] For example, if the target power consumption is 1.15kW, the current irradiance is 300W / m², and the power generation efficiency is 16%, inputting the target power consumption, power generation efficiency, and current irradiance into the unfolded area calculation formula, the unfolded area of ​​the auxiliary photovoltaic panel is calculated to be (1.15×1000) / (300×0.16)=23.96m².

[0074] S502, obtain the total unfolded area of ​​the auxiliary photovoltaic panel, and determine the unfolding degree of the auxiliary photovoltaic panel based on the unfolded area and the total unfolded area.

[0075] In this embodiment of the application, the total unfolded area of ​​the auxiliary photovoltaic panel can be obtained, and the unfolded degree of the auxiliary photovoltaic panel can be determined based on the unfolded area and the total unfolded area.

[0076] The unfolded area and the total unfolded area are input into the unfolding degree formula to calculate the unfolding degree of the auxiliary photovoltaic panel. The unfolding degree formula can be: D=(S_pv_need / S_pv_total)×100%; Where D represents the degree of unfolding of the auxiliary photovoltaic panel, S_pv_need represents the unfolded area, and S_pv_total represents the total unfolded area.

[0077] For example, if the total unfolded area of ​​the auxiliary photovoltaic panel is 2m² and the unfolded area is 0.8m², the unfolding degree of the auxiliary photovoltaic panel is: (0.8m² / 2m²)×100%=40%.

[0078] The above describes the specific process of determining the deployment degree of the auxiliary photovoltaic panel based on the current power consumption of the second power device and the current light intensity. Before determining the deployment degree of the auxiliary photovoltaic panel based on the current power consumption of the second power device and the current light intensity, it is necessary to determine whether the current light intensity is lower than a preset light intensity threshold. If the current light intensity is lower than the preset light intensity threshold, the auxiliary photovoltaic panel is controlled to deploy to its maximum extent to supply power to the second power device. If the current light intensity is not lower than the preset light intensity threshold, the step of determining the deployment degree of the auxiliary photovoltaic panel based on the current power consumption of the second power device and the current light intensity is executed, i.e., step S307. The preset light intensity threshold is a pre-set light intensity value (e.g., 300W / m²), used to measure whether the current light conditions are sufficient to support the auxiliary photovoltaic panel to deploy to its maximum extent. If the current light intensity is lower than the preset light intensity threshold, it indicates that the current light conditions are weak, and it is necessary to receive light to the maximum extent. Therefore, it is necessary to control the auxiliary photovoltaic panel to deploy to its maximum extent to supply power to the second power device. The maximum unfolding degree is 1 (or 100%), meaning that the auxiliary photovoltaic panels need to be fully unfolded.

[0079] S308 controls the auxiliary photovoltaic panel to unfold according to the unfolding degree to supply power to the second power device.

[0080] In this embodiment of the application, the expansion degree obtained through the above steps is used to control the auxiliary photovoltaic panel to expand according to the expansion degree in order to obtain light and convert light energy into electrical energy to power the second power device.

[0081] For example, if the expansion degree is 50%, and the auxiliary photovoltaic panel is composed of 4 photovoltaic panels of the same specifications, then the auxiliary photovoltaic panel is controlled to expand two of the photovoltaic panels to obtain sunlight and power the second power device.

[0082] In addition, before controlling the auxiliary photovoltaic panel to unfold to supply power to the second power device, it is necessary to determine the rationality of the unfolding degree, which may include the following steps: Step 1: Determine whether the degree of unfolding is less than the preset first degree of unfolding threshold, and if the degree of unfolding is less than the preset first degree of unfolding threshold, control the battery to supply power to the second power device.

[0083] In this embodiment, the first unfolding threshold is a lower limit (e.g., 1%) for defining the unfolding degree of the auxiliary photovoltaic panel. When the calculated unfolding degree is lower than the preset first unfolding threshold, it indicates that under the current illumination conditions, even if the auxiliary photovoltaic panel is partially unfolded, its power generation is relatively limited and its power generation efficiency is low. If it is forcibly unfolded at this time, the generated electrical energy may not be sufficient to offset its own power consumption and will cause unnecessary mechanical wear. Therefore, the unfolding of the auxiliary photovoltaic panel will be abandoned, and the system will switch to battery power supply mode, with the battery directly supplying power to the second power devices (such as the electronic control module and communication module). The battery serves as a backup power source.

[0084] Step 2: Determine whether the degree of unfolding is greater than the preset second degree of unfolding threshold. If the degree of unfolding is greater than the preset second degree of unfolding threshold, control the auxiliary photovoltaic panel to unfold to the maximum degree of unfolding to supply power to the second power device.

[0085] In this embodiment, the second deployment threshold is a boundary parameter value (e.g., 98%) used to define the near-full-load deployment, i.e., defining the upper limit of the auxiliary photovoltaic panel's power generation deployment. When the deployment degree exceeds this threshold, it indicates that the power demand of the second power device is very high, or the current light intensity is average, requiring the auxiliary photovoltaic panel to generate electricity at near its maximum area. At this time, it will be determined as a "maximum deployment required" state. To avoid frequent oscillations of control commands near the critical value and to simplify the control logic to improve response speed, the auxiliary photovoltaic panel can be directly commanded to deploy to its maximum extent to supply power to the second power device.

[0086] Step 3: If the degree of unfolding is not less than a preset first unfolding threshold and not greater than a preset second unfolding threshold, proceed to determine the degree of unfolding of the auxiliary photovoltaic panel based on the current power consumption of the second power device and the current light intensity. The preset first unfolding threshold is less than the preset second unfolding threshold.

[0087] In this embodiment, if the degree of expansion is not less than a preset first expansion threshold and not greater than a preset second expansion threshold, it indicates that the currently determined degree of expansion of the auxiliary photovoltaic panel is reasonable and effective. Therefore, the step of determining the degree of expansion of the auxiliary photovoltaic panel based on the current power consumption of the second power device and the current light intensity can be executed, i.e., step S307. The preset first expansion threshold is used to define the lower limit of the power generation expansion degree of the auxiliary photovoltaic panel, and the preset second expansion threshold is used to define the upper limit of the power generation expansion degree of the auxiliary photovoltaic panel. Therefore, the preset first expansion threshold is less than the preset second expansion threshold.

[0088] For example, if the second deployment threshold is preset to 100% and the first deployment threshold is preset to 10%, if the deployment degree is greater than 100%, it means that the area of ​​the auxiliary photovoltaic panel to be deployed exceeds the total deployment area. Even if it is fully deployed, it cannot meet the deployment degree. In this case, the deployment degree is set to 100%, that is, the auxiliary photovoltaic panel is deployed to the maximum extent. If the auxiliary photovoltaic panel is fully deployed, it still cannot meet the demand. The power generation gap is supplemented by the battery. If the deployment degree is less than 10%, it means that the required area is too small. The mechanical loss of deploying the auxiliary photovoltaic panel is greater than the power generation benefit. In this case, the deployment degree can be set to 0, that is, the auxiliary photovoltaic panel is not deployed and the battery directly supplies power. If the deployment degree is between 10% and 100%, the auxiliary photovoltaic panel is deployed according to the deployment degree.

[0089] In another embodiment of this application, the method further includes: detecting whether the photovoltaic air conditioner is in standby mode, and controlling the auxiliary photovoltaic panel to supply power to the photovoltaic air conditioner when the photovoltaic air conditioner is in standby mode.

[0090] like Figure 6 The diagram shown illustrates the implementation flow of another photovoltaic air conditioning power supply control method provided in this application embodiment. This method is applied to an intelligent power management module and may specifically include the following steps: S601, obtain the current electrical performance parameters of the main photovoltaic panel.

[0091] In this embodiment of the application, this step is similar to step S101 above, and will not be described in detail here.

[0092] S602, obtain any power device in the photovoltaic air conditioner and determine the functional positioning of the power device.

[0093] In this embodiment of the application, any power device in the photovoltaic air conditioner is obtained, and the functional positioning of the power device is determined. The functional positioning of the power device refers to whether the power device directly participates in the predetermined functions of the photovoltaic air conditioner (e.g., whether it directly participates in the "core cooling / heating" process).

[0094] Specifically, it is possible to traverse all power devices in a photovoltaic air conditioner and access a pre-stored device function database to obtain the functional positioning of each power device.

[0095] S603, where the power device is designated as the first power device, given that the power device is responsible for the predetermined function of the photovoltaic air conditioner.

[0096] In the embodiments of this application, when the power device is defined as the first power device, the power device is identified as the first power device, given that the power device is responsible for the predetermined function of the photovoltaic air conditioner.

[0097] For example, the compressor is the core power source of the refrigeration cycle, the outdoor fan motor is the heat dissipation guarantee for the condenser, the indoor fan motor is the power source for indoor air circulation, and the main control chip is the control center of the photovoltaic air conditioner power supply control system. Their functional positioning all represent that they are responsible for the predetermined functions of the photovoltaic air conditioner. Therefore, the compressor, outdoor fan motor, indoor fan motor, and main control chip are identified as the first power devices.

[0098] S604, where the power device is not responsible for the intended function of the photovoltaic air conditioner, the power device is identified as the second power device.

[0099] In the embodiments of this application, when the power device is not responsible for the predetermined function of the photovoltaic air conditioner, the power device is identified as the second power device.

[0100] It should be noted that if the functional positioning indicates that the power device is not responsible for the predetermined function of the photovoltaic air conditioner, that is, the power device is only responsible for auxiliary functions such as "control, monitoring, and communication" and does not directly participate in energy conversion, the photovoltaic air conditioner may still maintain basic cooling / heating even if it stops working (only losing intelligent control or data transmission capabilities).

[0101] For example, the communication module is only used for "data interaction between the photovoltaic inverter and the air conditioner" (such as transmitting photovoltaic power generation and air conditioner operating status), or "remote control between the air conditioner and the cloud" (such as APP temperature adjustment); the temperature sensor is only responsible for collecting ambient temperature to provide decision-making basis for the controller, and does not affect the refrigerant cycle itself.

[0102] Typically, the power consumption of the primary power device (such as a compressor) responsible for a predetermined function is much greater than that of the secondary power device (such as a communication module) that performs an auxiliary function.

[0103] S605, when the electrical performance parameters meet the power supply control conditions, performs the following power supply control operation: controls the main photovoltaic panel to supply power to the first power device, and controls the auxiliary photovoltaic panel to supply power to the second power device.

[0104] In this embodiment of the application, this step is similar to step S202 above, and will not be described in detail here.

[0105] like Figure 7 The diagram shown is a schematic representation of the implementation process of another photovoltaic air conditioning power supply control method provided in this application embodiment. This method is applied to an intelligent power management module and may specifically include the following steps: S701, obtain the current electrical performance parameters of the main photovoltaic panel.

[0106] In this embodiment of the application, this step is similar to step S301 above, and will not be described in detail here.

[0107] S702: Obtain any power device in the photovoltaic air conditioner and determine the control method of the power device.

[0108] In this embodiment, any power device in a photovoltaic air conditioner is obtained, and the control method of the power device is determined. The control method refers to the way the power device is driven. This includes control via a "power drive circuit," direct drive by a controller (such as a microcontroller), such as a compressor driven by an IGBT module / relay to avoid the controller directly bearing a large current; or a communication module connected to the microcontroller via a UART serial port, requiring only a weak signal for control.

[0109] S703, when the control mode is the preset control mode, the power device is determined as the first power device.

[0110] In the embodiments of this application, when the control mode is a preset control mode, the power device is determined as the first power device, wherein the preset control mode refers to the high-power device control mode using a "power drive circuit".

[0111] For example, the compressor, as the core power source of the refrigeration cycle, directly affects the cooling or heating effect of a photovoltaic air conditioner. Driven by an IGBT module, the compressor's speed and power can be precisely adjusted according to the load demand of the photovoltaic air conditioner, thus achieving efficient cooling or heating; therefore, it belongs to the first-level power device category. The outdoor fan motor ensures heat dissipation for the condenser, and its speed and operating time need to be adjusted according to the condenser's heat dissipation requirements. Driven by a relay, the start / stop and speed of the outdoor fan motor can be easily controlled, ensuring the condenser operates at a suitable temperature and improving the air conditioner's cooling efficiency; therefore, it also belongs to the first-level power device category.

[0112] S704: When the control mode is not the preset control mode, the power device is determined as the second power device.

[0113] In this embodiment, when the control method is not a preset control method, the power device is determined to be a second power device. The power consumption of the first power device is greater than that of the second power device. Specifically, if a power device adopts a low-power control mode of "direct controller drive", it is determined to be a second power device.

[0114] For example, the communication module only requires the microcontroller to send control commands via the UART serial port, thus it is classified as a second-level power device; the temperature sensor only requires a weak signal to trigger data acquisition, converting the ambient temperature information into an electrical signal and transmitting it to the controller. The controller adjusts the air conditioner's operating parameters based on the data collected by the temperature sensor, therefore it is also classified as a second-level power device.

[0115] S705, when the electrical performance parameters meet the power supply control conditions, performs the following power supply control operations: controls the main photovoltaic panel to supply power to the first power device, and controls the auxiliary photovoltaic panel to supply power to the second power device.

[0116] In this embodiment of the application, this step is similar to step S202 above, and will not be described in detail here.

[0117] In another embodiment of this application, the first power device and the second power device can also be determined based on the physical characteristics (size, weight and heat dissipation design) of any power device in the photovoltaic air conditioner.

[0118] Specifically, because high-power devices (first-power devices) generate a large amount of heat during operation, their physical design differs significantly from that of low-power devices (second-power devices). Specifically, in terms of size, high-power devices are typically larger to accommodate more heat dissipation structures and electronic components; they are also relatively heavier. In terms of heat dissipation design, high-power devices are generally equipped with larger heat sinks, fans, and other cooling devices. First-power and second-power devices can be distinguished by visually observing the size and heat dissipation structure of the power device, or by using simple measuring tools (such as a ruler or electronic scale) to measure its size and weight.

[0119] In another embodiment of this application, the first power device and the second power device can be determined based on the electrical characteristics corresponding to any power device in the photovoltaic air conditioner.

[0120] Specifically, they can be distinguished by their circuit connections and electrical parameters. High-power devices (first-power devices) need to be compatible with high voltage and high current (e.g., compressors are mostly 220V AC, with an operating current of 5-20A; some DC photovoltaic air conditioner compressors are 48V / 60V DC, with a current of 20-50A); while low-power devices (second-power devices) are mostly low voltage and low current (e.g., communication modules are mostly 5V / 12V DC, with an operating current of 10-500mA). By checking the circuit connection diagram of the power device and using a multimeter to measure its voltage, current, and other electrical parameters, the first-power device and the second-power device can be identified.

[0121] Furthermore, the photovoltaic air conditioning power supply control method provided in this application embodiment is illustrated with specific examples: The embodiments of this application, through dual optimization of structure and control logic, can improve the comprehensive utilization rate of photovoltaic energy and ensure the stable operation of key system functions.

[0122] Specifically, the design of the outdoor unit casing of the air conditioner includes a reserved area for embedding a rotatable and foldable photovoltaic panel. Under normal conditions, this photovoltaic panel serves as part of the air conditioner casing, providing structural support and shading. When sunlight is insufficient, it unfolds electrically or manually to obtain a better angle of sunlight for power generation. The electrical energy output from this photovoltaic panel is connected to an intelligent power management module via an independent line.

[0123] Furthermore, a retractable photovoltaic panel is embedded in the air conditioner's casing. This panel not only features a rotating and folding function but also automatically adjusts its extension length based on sunlight intensity, maximizing solar energy absorption. The panel is equipped with a telescopic guide rail and a light intensity sensor, which automatically adjusts the panel's unfolding degree according to the light intensity and angle. When the sunlight intensity is strong, the panel is fully unfolded to increase the light-receiving area; when the sunlight intensity is weak, the panel is partially unfolded or retracted to reduce energy loss and improve power generation efficiency.

[0124] The intelligent power management module, as the core control unit, monitors the output voltage and current of the main photovoltaic panel in real time via a voltage sensor. When the main photovoltaic panel voltage is detected to be below a set threshold (e.g., 10% below the rated voltage) for 5 seconds, it determines that the power generation is insufficient, automatically triggers the auxiliary photovoltaic panel to supply power, and switches to a low-load priority power supply mode. The response time is controlled within 0.5 seconds to ensure uninterrupted power supply to critical components. Users can also manually switch the power supply mode under specific operating conditions using a button to meet the needs of different users.

[0125] Meanwhile, artificial intelligence algorithms can be incorporated into the intelligent power management module. By learning from historical electricity consumption data, weather forecasts, and user habits, the system can predict the power generation capacity and load demand of the main photovoltaic panels in advance, dynamically optimize the main and auxiliary power supply switching strategy, and improve the overall energy efficiency of the system. For example, based on weather forecasts, the system can predict the intensity and duration of sunlight in the future and adjust the power supply ratio of the main and auxiliary photovoltaic panels in advance to avoid power outages due to insufficient sunlight.

[0126] In addition to monitoring voltage, the intelligent power management module can also integrate current and temperature sensors. Through multi-parameter fusion analysis, it can determine the power generation status of the main photovoltaic panel, avoiding erroneous switching due to fluctuations in a single parameter and improving stability. For example, when the voltage sensor detects a voltage fluctuation, it combines data from the current and temperature sensors to comprehensively determine whether the main photovoltaic panel has actually malfunctioned, avoiding power switching caused by misjudgment.

[0127] This application replaces the traditional centralized battery with a distributed energy storage system. Each indoor unit is equipped with an independent small battery, which coordinates the power supply strategy with the outdoor unit via a wireless communication module. This reduces power path delay, improves the response speed to abnormal power outages, and supports more flexible expansion. For example, when an indoor unit experiences an abnormal power outage and the outdoor unit cannot detect it, the independent small battery of that indoor unit automatically supplies power, enabling the indoor unit's mainboard to complete the shutdown process and send a fault alarm, thus preventing data loss and equipment damage caused by abnormal power outages.

[0128] In addition to powering small loads, the auxiliary photovoltaic (PV) panels generate electricity to charge the battery in the control box. This battery is connected to the mainboard of all indoor units via an independent circuit. When an indoor unit experiences an abnormal power outage and the outdoor unit cannot be detected, the battery automatically supplies power, enabling the indoor unit's mainboard to complete the shutdown process and send a fault alarm. Furthermore, the auxiliary PV panels can also provide power for the PV unit's standby mode. This involves actively shutting down the main PV panel through power switching and response control, thereby reducing the frequency of main PV panel usage, reducing the burden on the main PV panel or the grid, and lowering the overall system's standby power consumption. For example, at night or in low-light conditions, the auxiliary PV panels power the standby circuit of the air conditioner, maintaining its basic operating status while reducing reliance on the main PV panel or the grid.
