Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical appliances, in particular to a dust removal control method and device of a solar air conditioner and the solar air conditioner. BACKGROUND

[0002] In the prior art, some existing air conditioner products have a self-cleaning function. When cleaning is performed, the system can control the outdoor fan to reverse to blow away the dust on the surface of the outdoor heat exchanger by air flow. In addition, some models also introduce a frosting operation as an auxiliary cleaning means: after receiving a cleaning instruction, the refrigeration cycle is started to reduce the temperature of the surface of the outdoor heat exchanger and form a frost layer, and then the outdoor fan is reversed to complete the cleaning by air flow.

[0003] In the above system, the triggering of the frosting operation is usually directly driven by user instruction or preset program, and is irrelevant to the current energy supply condition. No matter the external power supply condition, as long as the cleaning instruction is received, the system performs the frosting and subsequent fan reversing operation according to the fixed flow. Therefore, the above-mentioned technology has the following defects: when the power supply capacity is insufficient to support the frosting operation, if the frosting and fan reversing are still performed according to the fixed flow, the system may not be able to complete the frosting due to insufficient power, resulting in that the cleaning effect cannot be achieved; and if the operation is forcibly maintained to ensure the completeness of the flow, additional power input is needed, causing the energy consumption to exceed the necessary range. SUMMARY

[0004] The present application provides a dust removal control method and device of a solar air conditioner and the solar air conditioner to solve the defects in the prior art and achieve the following effects: the present application directly links the execution of the frosting operation to the maximum power supply of the solar energy, so that the dust removal enhancement means with high energy consumption and high efficiency is only enabled when the green energy is sufficient, thereby actively enhancing the dust removal effect without additional consumption of grid energy and increase of system burden.

[0005] The present application provides a dust removal control method of a solar air conditioner, comprising: receiving a signal for dust removal of an outdoor heat exchanger, and controlling the solar air conditioner to enter a dust removal mode; in the dust removal mode, acquiring the maximum power supply of a solar power supply module at present; determining whether the maximum power supply meets the conditions for frosting of the outdoor heat exchanger, and determining the power supply mode and dust removal operation in the dust removal mode according to the determination result; in the case where the maximum power supply meets the conditions for frosting of the outdoor heat exchanger, controlling the power supply mode to be solar power supply only, and sequentially performing the frosting operation of the outdoor heat exchanger and the outdoor fan reversing operation.

[0006] According to some embodiments of the present application, the step of judging whether the maximum power supply meets the condition of the outdoor heat exchanger frosting comprises: obtaining a frost point temperature required for the outdoor heat exchanger frosting, and an environmental parameter of a current outdoor environment; judging whether the maximum power supply meets the condition of the outdoor heat exchanger frosting according to the frost point temperature, the environmental parameter, and the maximum power supply.

[0007] According to some embodiments of the present application, the step of judging whether the maximum power supply meets the condition of the outdoor heat exchanger frosting according to the frost point temperature, the environmental parameter, and the maximum power supply comprises: determining a compressor operating parameter required for the outdoor heat exchanger frosting according to the frost point temperature and the environmental parameter; determining a total compressor input power required for the outdoor heat exchanger frosting according to the compressor operating parameter; judging whether the maximum power supply meets the condition of the outdoor heat exchanger frosting according to a comparison result of the total compressor input power and the maximum power supply.

[0008] According to some embodiments of the present application, the step of judging whether the maximum power supply meets the condition of the outdoor heat exchanger frosting according to the comparison result of the preset input power and the maximum power supply comprises: in a case that the preset input power is less than or equal to the maximum power supply, the maximum power supply meets the condition of the outdoor heat exchanger frosting; in a case that the preset input power is greater than the maximum power supply, the maximum power supply does not meet the condition of the outdoor heat exchanger frosting.

[0009] According to some embodiments of the present application, the environmental parameter comprises an outdoor environment temperature and an outdoor environment humidity.

[0010] According to some embodiments of the present application, the step of sequentially executing the outdoor heat exchanger frosting operation and the outdoor fan reverse operation comprises: controlling the indoor fan and the outdoor fan to keep in a closed state; starting the compressor and controlling the compressor to reach a preset compressor parameter; determining that the outdoor heat exchanger reaches the frost point temperature, then starting the outdoor fan and controlling the outdoor fan to reverse after a preset frosting duration, so as to realize dust removal.

[0011] According to some embodiments of the present application, the preset compressor parameter is obtained according to the outdoor environment temperature and the frost point temperature, and the preset frosting duration is obtained according to the outdoor environment humidity.

[0012] According to some embodiments of the present application, after the step of judging whether the maximum power supply power meets the condition of frosting of the outdoor heat exchanger and determining the power supply mode and dust removal operation in the dust removal mode according to the judging result, the method further comprises: In the case that the maximum power supply power does not meet the condition of frosting of the outdoor heat exchanger, the power supply mode is controlled to be solar power priority and power grid supplementary power, and the outdoor fan reverse operation is performed.

[0013] In a second aspect, the present application protects a dust removal control device of a solar air conditioner, comprising: A first control module is configured to receive a signal for dust removal of an outdoor heat exchanger, and control the solar air conditioner to enter a dust removal mode. A first acquisition module is configured to acquire the current maximum power supply power of a solar power supply module in the dust removal mode. A second acquisition module is configured to judge whether the maximum power supply power meets the condition of frosting of the outdoor heat exchanger, and determine the power supply mode and dust removal operation in the dust removal mode according to the judging result. A second control module is configured to, in the case that the maximum power supply power meets the condition of frosting of the outdoor heat exchanger, control the power supply mode to be solar power supply only, and sequentially perform the frosting operation of the outdoor heat exchanger and the outdoor fan reverse operation.

[0014] In a third aspect, the present application protects a solar air conditioner, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to realize the dust removal control method of the solar air conditioner according to the first aspect of the present application.

[0015] In summary, the present application directly links the execution of the frosting operation to the maximum power supply power of the solar power, ensures that the dust removal enhancement method with high energy consumption and high benefit is only enabled when the green energy is sufficient, thereby actively strengthens the dust removal effect without additional consumption of power grid energy and increase of system burden, avoids the function failure or forced switching to the power grid due to insufficient power supply, and realizes the efficient self-cleaning without relying on the power grid.

[0016] Specifically, after receiving the dust removal signal, the system no longer directly performs the frosting and fan reverse, but first acquires the current maximum power supply power of the solar power supply module, and judges whether the frosting condition is met according to the maximum power supply power. Only when the judging result is met, the frosting operation and the outdoor fan reverse operation are sequentially performed.

[0017] Therefore, this control logic avoids initiating the frosting process when the power supply is insufficient to support frosting, thus preventing frosting failure or process interruption due to insufficient energy. Simultaneously, since frosting and reversal operations are only activated when conditions are met, the system will not perform high-energy-consuming actions under invalid operating conditions, improving the rationality and reliability of the control process.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0022] The dust removal control method, control device, and air conditioner of the solar-powered air conditioner proposed in this invention are described below with reference to the accompanying drawings. Before providing a detailed description of the embodiments of this invention, the overall application scenario is first described. The dust removal control method, control device, electronic device, and computer-readable storage medium of the solar-powered air conditioner of this invention can be applied locally to the solar-powered air conditioner, to cloud platforms in the Internet field, or to other types of cloud platforms in the Internet field, or to third-party devices. These third-party devices may include various types such as mobile phones, tablets, laptops, in-vehicle computers, and other smart terminals.

[0023] The following description uses only a dust control method applicable to solar air conditioners as an example. It should be understood that the dust control method of this invention can also be applied to cloud platforms and third-party devices.

[0024] like Figure 1 As shown, the dust removal control method for a solar-powered air conditioner according to a first aspect embodiment of the present invention includes: Step S1: Upon receiving a signal for dust removal from the outdoor heat exchanger, control the solar air conditioner to enter dust removal mode; Step S2: In dust removal mode, obtain the current maximum power supply of the solar power module; Step S3: Determine whether the maximum power supply meets the conditions for outdoor heat exchanger frosting, and determine the power supply mode and dust removal operation under dust removal mode based on the determination result. Step S4: When the maximum power supply meets the condition for the outdoor heat exchanger to frost, control the power supply mode to solar power only, and sequentially execute the outdoor heat exchanger frost operation and the outdoor fan reverse operation.

[0025] According to the dust removal control method of the solar-powered air conditioner of the present invention, in step S1, after receiving a dust removal command for the outdoor heat exchanger, the air conditioning control system enters a dust removal mode dedicated to performing cleaning tasks. Then, in the dust removal mode, the system obtains the maximum power supply currently available from the solar power module as the energy basis for subsequent decisions. The system further determines whether the maximum power supply is sufficient to support the outdoor heat exchanger to complete the frosting operation; based on the determination result, it determines whether to activate the enhanced dust removal process including frosting and its corresponding power supply mode. In step S4, when the determination result is that the frosting conditions are met, the system limits the power source to only solar energy and sequentially executes the frosting operation and the outdoor fan reversal operation to complete the enhanced dust removal.

[0026] The core of this invention lies in conditionally binding solar power supply capability with frosting-type dust removal operation, forming an intelligent dust removal control logic based on energy supply capability. Traditional air conditioners' fan reversal dust removal is usually independent of the energy source, performing the same operation regardless of power supply conditions, failing to balance cleaning effectiveness and energy sustainability.

[0027] In this invention, the enhanced dust removal mode of "frost + fan reversal" is activated only when the solar power module has sufficient capacity to support the frosting process, and this mode is limited to being powered by solar energy throughout. It can be understood that the frosting operation forms a frost layer on the heat exchanger surface; when the fan subsequently reverses, the frost layer melts and carries dust away from the fins, significantly improving the cleaning effect.

[0028] It should be noted that while frosting significantly improves dust removal efficiency, as the melting frost layer can peel off and trap stubborn dust from the fin surface, it has a high power requirement. Forcing this operation when energy is insufficient will lead to system instability or require switching to mains power, contradicting the goal of energy conservation. This invention links this high-efficiency mode to solar power supply, ensuring it is only activated when green energy is abundant. This avoids functional failure or forced switching to mains power due to insufficient power, thus achieving efficient self-cleaning without relying on the power grid.

[0029] Further, based on the above working principle, the specific working process of the dust removal control method of the present invention is as follows: In specific implementation, the air conditioner first responds to the dust removal signal and enters the dust removal mode. Subsequently, the system obtains the maximum power supply of the solar power module in real time, which reflects the upper limit of clean energy available under the current sunlight conditions. The system compares this power with the minimum power threshold required to achieve frosting. This threshold represents the power supply level necessary to complete an effective frosting operation and can be preset based on system calibration. If the current solar power is not lower than the threshold, it is determined that the energy conditions for performing the frosting operation are met. Under this premise, the system executes step S4: First, it forcibly limits the power supply path to pure solar power supply to ensure that no mains power is introduced throughout the process; second, it performs two operations in sequence—first, it forms a frost layer on the surface of the outdoor heat exchanger through the refrigeration cycle, and then it starts the outdoor fan to reverse, using the reverse airflow to cause the frost layer to fall off and carry away the dust.

[0030] Since this enhanced dust removal process is only triggered when solar energy is sufficient to support its full execution, it avoids energy waste and achieves efficient cleaning with zero mains power consumption, thus achieving enhanced dust removal without consuming excess energy.

[0031] In summary, by directly linking the execution of the frosting operation to the maximum power supply of solar energy, this invention ensures that the high-energy-consuming and high-efficiency dust removal enhancement method is only activated when green energy is sufficient. This achieves active enhancement of the dust removal effect without consuming additional grid energy or increasing the system burden, avoiding functional failure or forced switching to mains power due to insufficient power supply, and thus achieving efficient self-cleaning without relying on the grid.

[0032] Specifically, upon receiving a dust removal signal, the system no longer directly executes frosting and fan reversal. Instead, it first obtains the current maximum power supply of the solar power module and determines whether the frosting conditions are met. Only when the determination result is met will the frosting operation and the outdoor fan reversal operation be executed sequentially.

[0033] Therefore, this control logic avoids initiating the frosting process when the power supply is insufficient to support frosting, thus preventing frosting failure or process interruption due to insufficient energy. Simultaneously, since frosting and reversal operations are only activated when conditions are met, the system will not perform high-energy-consuming actions under invalid operating conditions, improving the rationality and reliability of the control process.

[0034] According to some embodiments of the present invention, the step of determining whether the maximum power supply meets the conditions for frosting of the outdoor heat exchanger includes: Obtain the frost point temperature required for the outdoor heat exchanger to frost, and the current outdoor environmental parameters; Based on the frost point temperature, environmental parameters, and maximum power supply, determine whether the maximum power supply meets the conditions for frost formation on the outdoor heat exchanger.

[0035] In this embodiment, when determining whether the maximum power supply meets the frosting conditions of the outdoor heat exchanger, two key pieces of information are first obtained: the frost point temperature required for the outdoor heat exchanger to frost, and the environmental parameters of the current outdoor environment (such as ambient temperature and humidity). Then, by combining the frost point temperature, environmental parameters, and the obtained maximum power supply, a comprehensive judgment is made as to whether the maximum power supply is sufficient to support the execution of the frosting operation.

[0036] In this way, by incorporating the frost point temperature and actual environmental parameters, the above steps ensure that the judgment of frost conditions not only depends on power supply capacity but also takes into account the actual state of the current thermodynamic environment, thereby improving the accuracy and adaptability of the judgment. Compared with the judgment method based solely on a fixed power threshold, this method can more realistically reflect the feasibility of frost operation in the current environment, avoiding misjudgments or invalid executions due to ignoring environmental factors.

[0037] In some specific embodiments of the present invention, the step of determining whether the maximum power supply meets the conditions for frosting of the outdoor heat exchanger based on the frost point temperature, environmental parameters, and maximum power supply includes: Based on the frost point temperature and environmental parameters, determine the compressor operating parameters required for the outdoor heat exchanger to frost. Determine the total compressor input power required to achieve frosting of the outdoor heat exchanger based on the compressor operating parameters; Based on the comparison between the compressor's total input power and the maximum power supply, determine whether the maximum power supply meets the conditions for the outdoor heat exchanger to frost.

[0038] In this embodiment, the process of determining whether the maximum power supply meets the frosting conditions includes three sub-steps: First, based on the frost point temperature and current outdoor environmental parameters (such as ambient temperature and humidity), determine the compressor operating parameters (such as operating frequency, start-stop sequence, etc.) required to achieve frosting; second, based on the compressor operating parameters, calculate the total compressor input power required to complete the frosting operation; finally, compare the total compressor input power with the current maximum power supply of the solar power module. If the maximum power supply is not lower than the required total input power, it is determined that the frosting conditions are met; otherwise, it is determined that the conditions are not met.

[0039] In this way, the above steps transform the judgment of frosting conditions into a quantitative assessment of the compressor's actual energy consumption requirements, changing the judgment basis from the abstract question of "whether it is sufficient" to power matching based on specific operating parameters. By introducing the calculation of compressor operating parameters and total input power, the determination of frosting conditions is closely related to the actual working state of the air conditioning system, significantly improving the engineering feasibility and control accuracy of the judgment, and avoiding false triggering or execution failure caused by power estimation errors.

[0040] Furthermore, based on the comparison between the preset input power and the maximum power supply, it is determined whether the maximum power supply meets the conditions for frosting of the outdoor heat exchanger, including: If the preset input power is less than or equal to the maximum power supply, then the maximum power supply meets the condition for the outdoor heat exchanger to frost. If the preset input power is greater than the maximum power supply, the maximum power supply will not meet the conditions for the outdoor heat exchanger to frost.

[0041] It is understood that in this embodiment, the final judgment of the frosting conditions is achieved through direct comparison. Specifically, the preset input power required to achieve frosting of the outdoor heat exchanger is compared with the current maximum power supply of the solar power module. If the preset input power is less than or equal to the maximum power supply, it is determined that the maximum power supply meets the frosting conditions. If the preset input power is greater than the maximum power supply, it is determined that the frosting conditions are not met.

[0042] Thus, this method uses explicit numerical comparison logic as the basis for judgment, making the process of determining frosting conditions deterministic and executable. That is, by setting a clear power magnitude relationship as the judgment threshold, it avoids fuzzy judgment or empirical decision-making, improves the reliability and response consistency of the control system, and facilitates fast and accurate logical judgment.

[0043] Furthermore, environmental parameters include outdoor ambient temperature and outdoor ambient humidity.

[0044] In this embodiment, the environmental parameters used to determine the frosting conditions specifically include outdoor ambient temperature and outdoor ambient humidity. These two parameters together reflect the current thermodynamic state of the atmosphere. Thus, by analyzing these two parameters, the frost point temperature can be determined and the potential for frosting on the heat exchanger surface can be assessed.

[0045] It is understandable that temperature and humidity directly determine the saturation state of water vapor in the air and the location of the frost point. Incorporating these factors into the judgment criteria helps to more accurately assess the actual feasibility of achieving frost formation under current meteorological conditions, thereby improving the rationality and effectiveness of the entire dust control strategy.

[0046] According to some embodiments of the present invention, the steps of sequentially performing the outdoor heat exchanger frosting operation and the outdoor fan reversal operation include: Keep both the indoor and outdoor fans off. Start the compressor and control it to reach the preset compressor parameters; Once the outdoor heat exchanger reaches the frost point temperature, after a preset frost duration, the outdoor fan is started and controlled to reverse to remove dust.

[0047] In this embodiment, after determining that the maximum power supply meets the frosting conditions, the system sequentially performs frosting and outdoor fan reversal operations. At this time, under the condition of only solar power supply, the specific dust removal operation process of the dust removal mode of the present invention is as follows: First, both the indoor and outdoor fans are kept off to avoid airflow disturbance affecting the temperature drop of the heat exchanger surface. Then, the compressor is started and its operating status is adjusted to preset compressor parameters, such as preset operating frequency or target discharge temperature, so that the refrigerant continues to evaporate and absorb heat in the outdoor heat exchanger. When the outdoor heat exchanger surface temperature is detected to have dropped to the frost point temperature, the preset frost duration is started. After the preset frost duration ends, the outdoor fan is started and controlled to run in reverse direction. The reverse airflow causes the frost layer on the heat exchanger surface to fall off and carry away the attached dust, thereby completing the dust removal.

[0048] In summary, in the above dust removal operation, this method effectively reduces the interference of external airflow on the heat exchanger surface by shutting down the indoor and outdoor fans during the frosting stage, which is conducive to the uniform and stable formation of the frost layer. After confirming that the frost point temperature has been reached, a preset frosting time is introduced to ensure that the frost layer has sufficient thickness to perform its cleaning function. Subsequently, the outdoor fan is started in reverse to achieve efficient dust removal based on the frost layer. The entire process is controlled in an orderly manner through three stages of "static setting - frosting - reversal," which closely connects the frosting operation with the dust removal action in terms of timing and state, improving the reliability and cleaning effect of frosting-assisted dust removal.

[0049] Furthermore, the preset compressor parameters are obtained based on the outdoor ambient temperature and the frost point temperature; the preset frosting duration is obtained based on the outdoor ambient humidity.

[0050] In this embodiment, the preset compressor parameters are set based on the current outdoor ambient temperature. The preset values ​​differ for different temperature zones, with the minimum requirement being that the condenser can frost under the current outdoor ambient temperature and relative humidity of 30% or higher. As for the preset frosting duration, its duration is determined by the current relative humidity. For example, the higher the relative humidity, the shorter the preset frosting duration, and vice versa.

[0051] Specifically, in this embodiment, when performing a frosting operation, the system first acquires the current outdoor ambient temperature and the frost point temperature, and determines the required operating intensity of the compressor based on the difference between the two, thereby setting preset compressor parameters (such as target operating frequency or load level). These parameters ensure that the cooling capacity output by the compressor is sufficient to reduce the surface temperature of the outdoor heat exchanger to the frost point and maintain the frosting state within a reasonable time.

[0052] Meanwhile, the system acquires the current outdoor humidity and determines the preset frosting time based on this humidity value. In environments with high relative humidity, the water vapor content in the air is high, and the frost layer forms faster, so a shorter frosting time is set; in environments with low relative humidity, the frost layer forms more slowly, so the frosting time is extended accordingly to ensure that the frost layer reaches the thickness required for effective cleaning.

[0053] All of the above parameters are set before the frosting operation is started and are used for subsequent compressor control and timing logic.

[0054] In summary, this invention links preset compressor parameters with outdoor ambient temperature and frost point temperature, enabling the compressor's operating intensity to dynamically match the frosting requirements under current thermodynamic conditions. This avoids frosting failure due to insufficient cooling or energy waste due to excessive cooling. Simultaneously, it links the preset frosting duration with outdoor ambient humidity, allowing the frost layer growth time to adapt to different humidity environments, ensuring the formation of the necessary frost thickness for effective cleaning under various climatic conditions.

[0055] like Figure 2As shown, according to some embodiments of the present invention, after determining whether the maximum power supply meets the conditions for frosting of the outdoor heat exchanger, and determining the power supply mode and dust removal operation under dust removal mode based on the determination result, the method further includes: If the maximum power supply is insufficient to meet the conditions for outdoor heat exchanger frosting, the power supply mode is controlled to prioritize solar power supply with supplementary mains power supply, and the outdoor fan is reversed.

[0056] In this embodiment, after the system determines whether the maximum power supply meets the frosting conditions of the outdoor heat exchanger, if the determination result is that the frosting conditions are not met, an alternative dust removal strategy is entered: the system sets the power supply mode to prioritize solar power supply and supplement the mains power supply, that is, the power output of the solar power module is used first to drive the dust removal operation. When the solar power supply is insufficient to maintain the normal operation of the fan, the mains power is automatically activated to supplement the power to ensure operational stability. In this power supply mode, the system performs the outdoor fan reversal operation to blow away the dust accumulated on the surface of the outdoor heat exchanger through the reverse airflow, thus completing the basic dust removal task.

[0057] The process does not include frosting operations; it only involves reversing the fan, and the power supply strategy dynamically coordinates the ratio of solar power to grid power based on the actual energy supply capacity.

[0058] Thus, even when the maximum power supply is insufficient to support frosting operations, this method can still perform fan reversal dust removal through a combination of solar and mains power, ensuring effective operation of the dust removal function under various lighting conditions and improving system availability and environmental adaptability. Simultaneously, the "solar power priority, mains supplement" power supply strategy maximizes the use of renewable energy while ensuring functional implementation, balancing cleanliness and energy efficiency. These steps avoid the problem of completely abandoning dust removal operations due to insufficient solar power, achieving a balance between functional continuity and energy optimization.
