Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to an anti-condensation method for an air conditioner, an electronic device, and an air conditioner. Background Technology

[0002] When traditional air conditioners operate in cooling or dehumidification modes, the surface temperature distribution of the indoor heat exchanger is not perfectly uniform. Due to uneven refrigerant distribution, differences in airflow field distribution, partial blockage of fins, or gaps in assembly, the temperature of the indoor heat exchanger surface, air outlet frame, air guide plate, and internal air ducts may be lower than the dew point temperature of the indoor air, leading to condensation. Accumulated and dripping condensation can affect user experience and may infiltrate critical components such as the electrical box, causing equipment malfunctions or safety hazards. Therefore, anti-condensation control is one of the key technologies for ensuring the reliability of air conditioners and a good user experience.

[0003] Existing anti-condensation control methods mostly adopt extensive adjustments such as increasing the overall fan speed, raising the set temperature, or strengthening dehumidification globally. They do not implement precise control for local low temperature points, which can easily lead to increased operating noise, increased energy consumption, and decreased comfort, and cannot eliminate the risk of local condensation at the root. Summary of the Invention This application provides an anti-condensation method, electronic device, and air conditioner for an air conditioner, which at least solves the technical problems of existing anti-condensation control methods being crude in their regulation, lacking local targeted adjustment, and easily increasing noise and energy consumption.

[0004] According to a first aspect of the embodiments of this application, an anti-condensation method for an air conditioner is provided, wherein the air conditioner operates in an anti-condensation mode, and the anti-condensation method includes: When the air conditioner is in the anti-condensation mode, the indoor temperature and humidity, as well as the temperature of multiple monitoring points located in different areas of the indoor unit, are dynamically acquired. The current air dew point temperature is determined based on the indoor temperature and humidity, and the target monitoring point with condensation risk and the condensation risk level of the target monitoring point are determined based on the air dew point temperature and the temperatures of the multiple monitoring points. Based on the location of the target monitoring point and the condensation risk level, the corresponding anti-condensation strategy is executed.

[0005] This embodiment, through multi-point temperature monitoring combined with dew point temperature determination, can accurately pinpoint the specific location of condensation risk within the indoor unit. By introducing a condensation risk level classification mechanism, differentiated anti-condensation strategies are adopted based on the degree of risk, avoiding a one-size-fits-all approach to global adjustments. While ensuring anti-condensation effectiveness, it reduces negative impacts on the air conditioner's cooling / dehumidification capacity, operating noise, and energy consumption. By matching corresponding control strategies to the target monitoring point locations, the anti-condensation control is made more aligned with the indoor unit's structure and airflow distribution characteristics. This addresses the root cause of condensation problems caused by localized low temperatures, improving the air conditioner's operational reliability and user comfort, while also achieving energy savings.

The first control strategy includes: adjusting the operating parameters of the cross-flow fan blades according to the location of the target monitoring point to increase the airflow at the target monitoring point. If the risk level of the target monitoring point is Level 1 and the target monitoring point is located at the third monitoring point, a second control strategy is executed.

Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply differentness. Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0031] First, we will introduce the application scenarios of anti-condensation methods in the field of air conditioning.

[0032] The anti-condensation method in this embodiment is mainly applicable to wall-mounted, cabinet, and built-in air conditioners operating in cooling or dehumidification mode. It is especially suitable for usage scenarios that are sensitive to wind speed and noise, such as silent operation, sleep operation, and low-load stable operation. It can achieve precise anti-condensation control inside the indoor unit and the air outlet area without compromising user comfort.

[0033] Taking a wall-mounted split air conditioner as an example, its indoor unit mainly includes an indoor heat exchanger, cross-flow fan blades, air ducts, air guide plates, electronic expansion valves, compressors, etc.; multiple temperature monitoring points are arranged inside the indoor unit, distributed in the heat exchanger area, air duct area and air outlet area, so as to realize real-time collection and monitoring of the temperature of easily condensing parts.

[0034] The anti-condensation method of this embodiment will be described in detail below.

[0035] This embodiment provides a method for preventing condensation in an air conditioner. The air conditioner's operating mode includes an anti-condensation mode, as described below. Figure 1 The flowchart shows that the anti-condensation method includes the following steps: S11. When the air conditioner is in anti-condensation mode, dynamically acquire indoor temperature and humidity, as well as the temperature of multiple monitoring points located in different areas of the indoor unit. S12. Determine the current air dew point temperature based on indoor temperature and humidity, and determine the target monitoring point with condensation risk and the condensation risk level of the target monitoring point based on the air dew point temperature and the temperatures of multiple monitoring points. S13. Implement the corresponding anti-condensation strategy based on the location of the target monitoring point and the condensation risk level.

[0036] Specifically, in combination Figure 5 and Figure 6 The flowchart illustrates that after the air conditioner enters anti-condensation mode, it first dynamically acquires the current indoor temperature and humidity information through a temperature and humidity acquisition device. Simultaneously, it collects the real-time temperature T_ at each of the corresponding monitoring points using multiple temperature detection devices deployed at various monitoring points in different areas of the indoor unit. i (i=1,2,…,n), thereby gaining a comprehensive understanding of the temperature distribution inside the indoor unit and providing a data foundation for subsequent condensation risk assessment.

[0037] Then, based on the acquired indoor temperature and humidity data, the air dew point temperature T_ under the current environment is calculated. dp By comparing and analyzing the real-time temperature and dew point temperature of each monitoring point, target monitoring points with low temperatures and potential condensation risks are identified, and the condensation risk level of the corresponding target monitoring points is determined.

[0038] Dew point temperature is the temperature at which the gaseous water in the air must drop to reach saturation and condense into liquid water under a fixed atmospheric pressure. The air conditioner's control module calculates the dew point temperature based on the real-time indoor temperature and humidity data and the thermodynamic relationship between saturated water vapor pressure and air temperature; or it determines the current ambient dew point temperature by looking up a table using a pre-calibrated and stored temperature-humidity-dew point temperature mapping relationship.

[0039] Finally, for target monitoring points at different locations and corresponding condensation risk levels, appropriate anti-condensation strategies are adopted to achieve graded and targeted regulation, eliminating the risk of condensation while avoiding excessive adjustment that could affect the air conditioning performance and user experience.

[0040] This embodiment, through multi-point temperature monitoring combined with dew point temperature determination, can accurately pinpoint the specific location of condensation risk within the indoor unit. By introducing a condensation risk level classification mechanism, differentiated anti-condensation strategies are adopted based on the degree of risk, avoiding a one-size-fits-all approach to global adjustments. While ensuring anti-condensation effectiveness, it reduces negative impacts on the air conditioner's cooling / dehumidification capacity, operating noise, and energy consumption. By matching corresponding control strategies to the target monitoring point locations, the anti-condensation control is made more aligned with the indoor unit's structure and airflow distribution characteristics. This addresses the root cause of condensation problems caused by localized low temperatures, improving the air conditioner's operational reliability and user comfort, while also achieving energy savings.

[0041] It should be noted that the anti-condensation mode can be executed based on user control commands or automatically activated according to the air conditioner's operating status. For example, when the air conditioner is running in cooling or dehumidification mode and the indoor fan speed is lower than the preset speed, it will automatically enter the anti-condensation mode. The preset speed is, for example, 35% of the rated maximum speed, corresponding to low fan speed conditions such as silent mode and sleep mode, ensuring that the anti-condensation control is executed without affecting the user's quiet experience.

[0042] In one alternative implementation, refer to Figure 2 The flowchart describes how to determine the target monitoring points at risk of condensation, and the condensation risk level of each target monitoring point, based on the air dew point temperature and the temperatures of multiple monitoring points. The process includes the following steps: S21. Determine the average temperature value of multiple monitoring points; S22. Determine the temperature deviation of each monitoring point relative to the average temperature value, and the condensation risk temperature difference of each monitoring point relative to the current air dew point temperature. S23. Determine the target monitoring points with condensation risk and the condensation risk level of the target monitoring points based on the temperature deviation and the temperature difference of condensation risk.

[0043] Specifically, in combination Figure 5 and Figure 6 The flowchart first statistically calculates the temperatures collected from multiple monitoring points in different areas of the indoor unit to obtain the overall average temperature T_ of the above multiple monitoring points. avg Then, the difference between the temperature at each monitoring point and the average temperature is calculated to obtain the temperature deviation ΔT_ at that monitoring point. i ΔT_ i = T_ i - T_ avgIt is used to reflect the degree of temperature anomaly at that location relative to the whole machine; at the same time, it calculates the difference between the temperature at each monitoring point and the current air dew point temperature to obtain the condensation risk temperature difference ΔT_ risk _ i ΔT_ risk _ i = T_ i - T_ dp It is used to characterize the likelihood of condensation occurring at that location.

[0044] Finally, by combining the two dimensions of temperature deviation and condensation risk temperature difference, monitoring points that simultaneously meet the criteria of abnormally low temperature and are close to or below the dew point temperature are selected as target monitoring points. The condensation risk level is further divided according to the size of the temperature difference, so as to achieve accurate identification and classification of condensation risk.

[0045] For example, determining the target monitoring point with condensation risk and the condensation risk level of the target monitoring point based on the temperature deviation and the condensation risk temperature difference includes: determining the monitoring point that meets the condition of temperature deviation < preset deviation threshold and condensation risk temperature difference < preset safety margin for a continuous first preset duration as the target monitoring point; determining the corresponding condensation risk level based on the condensation risk temperature difference of the target monitoring point, and the smaller the condensation risk temperature difference, the higher the corresponding condensation risk level.

[0046] Specifically, in combination Figure 5 and Figure 6 The flowchart shows that when a certain monitoring point is within a first preset time period (t1), the temperature deviation (ΔT_) is... i ) < preset deviation threshold (-δ1), and condensation risk temperature difference (ΔT_ risk _ i If the temperature at the monitoring point is significantly lower than the preset safety margin (S), it indicates that the temperature at the monitoring point is significantly lower than the overall average level and is close to the dew point, posing a risk of condensation. This monitoring point is the target monitoring point, and the location i of the target monitoring point is recorded.

[0047] Then, the condensation risk level is determined based on the condensation risk temperature difference (ΔT_risk_i) at the target monitoring point. The higher the condensation risk level, the higher the risk of condensation.

[0048] For example, if 0℃ ≤ condensation risk temperature difference (ΔT_risk_i) < S, it is classified as a Level 1 risk, indicating that the temperature at the target monitoring point has not yet fallen below the dew point, but there is a significant downward trend and condensation is imminent. When the condensation risk temperature difference (ΔT_risk_i) < 0℃, it is classified as a Level 2 risk, indicating that the temperature at the target monitoring point has already fallen below the dew point, and condensation may be occurring or is about to occur. Here, S is the preset safety margin. In a specific example, the first preset duration is 3 minutes, the preset deviation threshold is -2.5℃, and the preset safety margin is 1.0℃.

[0049] This embodiment uses the average temperature of multiple monitoring points as a benchmark to determine temperature deviation, effectively eliminating the interference of overall ambient temperature fluctuations and more accurately identifying abnormal areas of localized low temperatures, thus avoiding misjudgments. By combining temperature deviation and condensation risk temperature difference as dual indicators, it can identify localized low temperatures and directly reflect the actual risk of condensation formation, improving the reliability of condensation prediction. Through comprehensive determination of target monitoring points and risk levels using dual parameters, it achieves quantitative differentiation of condensation risk, providing a basis for subsequent tiered and precise control, making condensation prevention and control more rational and efficient.

[0050] In one alternative implementation, refer to Figure 3 The flowchart illustrates that the air conditioner is equipped with a multi-level anti-condensation strategy with progressively increasing adjustment intensity. Each anti-condensation strategy includes multiple anti-condensation sub-strategies adapted to the location of the target monitoring point. Based on the location of the target monitoring point and the condensation risk level, the corresponding anti-condensation strategy is executed, including the following steps: S31. Determine the target anti-condensation strategy based on the risk level of the target monitoring point; S32. Determine the target anti-condensation sub-strategy based on the location of the target monitoring point and the target anti-condensation strategy; S33. Use a target-based anti-condensation strategy to regulate condensation.

[0051] Specifically, the air conditioner is pre-configured with a multi-level anti-condensation strategy. Each level of the anti-condensation strategy increases in intensity to accommodate different levels of condensation risk. Each level of anti-condensation strategy includes multiple sub-strategies, and each sub-strategy corresponds to the structure and airflow characteristics of the area where different monitoring points of the indoor unit are located.

[0052] After determining the risk level of the target monitoring point, the target anti-condensation strategy is determined based on the determined risk level. The higher the risk level of the target monitoring point, the more significant the condensation trend, and the stronger the corresponding target anti-condensation strategy, thus achieving a match between risk and control intensity.

[0053] Then, based on the location of the target monitoring point, a target anti-condensation sub-strategy is determined from the target anti-condensation strategy, so that the control method is more in line with the actual working conditions of the corresponding area.

[0054] Finally, the determined target anti-condensation sub-strategy is adopted to implement anti-condensation regulation, thereby achieving precise and targeted anti-condensation control.

[0055] For example, in combination Figure 6If the condensation risk level at the target monitoring point is Level 1, then strategy A or strategy B from the Level 1 anti-condensation strategy is selected. If the Level 1 anti-condensation strategy is ineffective, it is upgraded to the Level 2 anti-condensation strategy. If the condensation risk level at the target monitoring point is Level 2, then strategy A + strategy C, or strategy B + strategy C from the Level 2 anti-condensation strategy is selected. If the Level 2 anti-condensation strategy is ineffective, it is upgraded to strategy D or strategy E.

[0056] This embodiment adjusts the system according to risk level and executes it according to the location of monitoring points. While ensuring the anti-condensation effect, it avoids over-adjustment and takes into account the quietness, comfort and energy economy of operation.

[0057] In one alternative implementation, after using a target anti-condensation sub-strategy for anti-condensation control, the anti-condensation method further includes: determining whether the condensation risk at the target monitoring point has been eliminated; if the condensation risk at the target monitoring point has not been eliminated and the current anti-condensation strategy level has not reached the highest level, then the next level anti-condensation strategy is used as the new target anti-condensation strategy, and anti-condensation control is performed again.

[0058] Specifically, in combination Figure 6 The flowchart illustrates that after completing one round of anti-condensation control using the current target anti-condensation sub-strategy, the controller continues to collect temperature data from the target monitoring point and, combined with the dew point temperature, determines whether the condensation risk at that location has been eliminated. If the condensation risk is determined to still exist, and the currently used anti-condensation strategy has not yet reached the preset maximum control level, then the next level of anti-condensation strategy with higher control intensity is automatically adopted as the new target anti-condensation strategy. Anti-condensation control is then executed again according to the method of matching the corresponding sub-strategy to the location of the aforementioned target monitoring point, until the condensation risk is eliminated. If the condensation risk is determined to still exist, and the currently used anti-condensation strategy has reached the preset maximum control level, then anti-condensation control is stopped, and a prompt message is issued to the user.

[0059] In one example, determining whether the condensation risk at the target monitoring point has been eliminated includes: comparing the condensation risk temperature difference at the target monitoring point with a preset value, where the preset value is greater than a preset safety margin; and determining that the condensation risk at the target monitoring point has been eliminated if the condensation risk temperature difference remains higher than the preset value for a second preset duration. For example, the preset value is S + 0.5℃, where S is the preset safety margin, and the second preset duration is 10 minutes.

[0060] This embodiment achieves a step-by-step upgrade of anti-condensation control, automatically increasing the control intensity when the risk has not been eliminated. This ensures that the condensation problem can be effectively solved, while avoiding the use of the highest intensity adjustment from the beginning. This helps maintain the comfort and quietness of air conditioning operation and reduce energy consumption.

[0061] In one optional implementation, the anti-condensation method further includes: during the execution of the target anti-condensation strategy, if the condensation risk temperature difference is continuously higher than a preset value within a third preset time period, the adjustment intensity is increased according to a preset gradient; wherein, the third preset time period is less than the second preset time period.

[0062] Specifically, during the execution of the current anti-condensation strategy, the controller calculates and monitors the condensation risk temperature difference corresponding to the target monitoring point in real time, continuously comparing it with a preset value. If the condensation risk temperature difference remains higher than the preset value within a third preset time period, it indicates that the current adjustment intensity is insufficient to quickly eliminate the condensation hazard. The controller then gradually increases the adjustment intensity according to a preset gradient, for example, by increasing the wind speed increase ratio, to enhance the anti-condensation effect. The third preset time period is set to be less than or equal to the second preset time period for determining that the risk has been completely eliminated, thereby achieving early intervention and preventing the risk from persisting. For example, the preset value is S + 0.5℃, where S is the preset safety margin, and the third preset time period is 5 minutes.

[0063] This embodiment enhances the control intensity in advance before the risk is completely eliminated, achieving earlier and more proactive anti-condensation control and shortening the condensation elimination time; at the same time, by gradually increasing the intensity rather than jumping directly to the highest intensity, it takes into account both the control effect and the comfort, quietness and energy saving of the air conditioner operation.

[0064] In one alternative implementation, the anti-condensation method further includes: After each anti-condensation mode ends, the location information of the target monitoring point, indoor temperature and humidity, and effective anti-condensation strategies are also recorded. The effective anti-condensation strategy is the anti-condensation strategy executed when the risk of condensation is eliminated. When the anti-condensation mode is run again, the corresponding historical effective anti-condensation strategies are retrieved and executed first based on the location information of the target monitoring point and indoor temperature and humidity.

[0065] Specifically, after each anti-condensation mode operation is completed and the condensation risk is eliminated, the controller records data for this operation, saving the location information of the target monitoring point area, the corresponding indoor temperature and humidity conditions, and the effective anti-condensation strategy used to successfully eliminate the condensation risk, forming a historical operation database. When the air conditioner meets the conditions for entering the anti-condensation mode and starts running again, the controller first obtains the current target monitoring point location and indoor temperature and humidity information, matches it with the operating conditions in the historical records, retrieves the corresponding historical effective anti-condensation strategies under the same or similar operating conditions, and prioritizes directly using that strategy for control.

[0066] This embodiment reduces repeated trial-and-error adjustment processes by learning from and reusing historically effective strategies, accelerates the elimination of condensation risks, improves control response efficiency and stability, and makes anti-condensation control more closely match the actual operating conditions of the air conditioner, further enhancing the user experience.

[0067] In one optional implementation, the anti-condensation method further includes: determining that the air conditioner has a structural air leakage fault when the target monitoring point simultaneously meets the following conditions: the temperature rise rate in the anti-condensation mode is lower than a preset threshold; the air conditioner re-enters the condensation risk state within a fourth preset time period after the condensation risk has been eliminated; the cumulative number of times the air conditioner is identified as a target monitoring point under similar or identical indoor temperature and humidity conditions reaches a preset number; and issuing a prompt message to the user when the air conditioner is determined to have an air leakage fault.

[0068] Specifically, during long-term operation of an air conditioner, non-design-related assembly gaps may occur due to reasons such as improper reassembly after user cleaning or microscopic deformation of the product during transportation or installation. To intelligently distinguish between the condensation risk caused by such fixed air leakage points and the condensation risk caused by occasional temperature unevenness such as refrigerant unevenness, the controller continuously monitors the temperature changes, state switching frequency, and historical patterns of the target monitoring points during the anti-condensation control process, and comprehensively determines whether the air conditioner has a structural air leakage fault.

[0069] When a target monitoring point simultaneously meets the following three conditions, it is determined that the condensation risk at that monitoring point is not caused by occasional temperature unevenness due to uneven refrigerant distribution, but by structural air leakage faults: Condition 1: When the temperature rise rate at the target monitoring point is lower than the preset threshold under the anti-condensation mode, it indicates that the local airflow is abnormal and conventional control is not able to quickly raise the temperature; for example, the preset threshold is less than or equal to 0.3℃ / min.

[0070] Condition 2: After the condensation risk is eliminated, the target monitoring point returns to the condensation risk state within a preset time period, which is manifested as repeated condensation problems that are difficult to eradicate; for example, the fourth preset time period is less than or equal to 2 minutes. Condition 3: Under similar or identical indoor temperature and humidity conditions, if the cumulative number of times the monitoring point is identified as having a risk of condensation reaches a preset number, and occasional factors are excluded, it is confirmed as a persistent anomaly. For example, the preset number is greater than or equal to 3 times.

[0071] After confirming a structural air leakage fault in the air conditioner, the controller sends fault alerts to the user via display, sound, or wireless push notifications to facilitate timely repair. For example, a user-friendly alert can be sent via the air conditioner's display screen, indicator lights, or a linked app, such as: "Abnormal airflow detected on the right side, which may affect noise reduction. We recommend contacting after-sales service for inspection." Simultaneously, detailed diagnostic data (such as fault codes, suspected locations, frequency of occurrence, and historical temperature curves) is stored or uploaded to the cloud. After-sales service personnel can then access this information using specialized equipment for precise location tracking.

[0072] This embodiment can automatically distinguish between condensation under normal operating conditions and structural air leakage faults while controlling condensation, thus achieving fault self-diagnosis; by comprehensively judging multiple conditions, it can improve the accuracy of fault identification and avoid false alarms; it can promptly alert users to faults, making it easier to maintain in advance and avoid problems such as condensation dripping water and component corrosion caused by long-term air leakage, thereby improving the reliability and service life of the air conditioner.

[0073] In one alternative implementation, the multiple monitoring points include a first monitoring point located on the indoor heat exchanger, a second monitoring point located in the air duct and near the air inlet of the cross-flow fan blades, and a third monitoring point located in the air outlet area of ​​the air conditioner. Based on the location of the target monitoring point and the condensation risk level, implement corresponding anti-condensation strategies, including: If the risk level of the target monitoring point is Level 1 and the target monitoring point is located at the first monitoring point and / or the second monitoring point, the first control strategy shall be implemented. The first control strategy includes: adjusting the working parameters of the cross-flow fan blades according to the location of the target monitoring point in order to increase the airflow at the target monitoring point. If the risk level of the target monitoring point is Level 1 and the target monitoring point is located at the third monitoring point, the second control strategy is implemented. The second control strategy includes: adjusting the air guide angle of the air guide plate according to the location of the target monitoring point so that at least part of the airflow sweeps the target monitoring point.

[0074] Specifically, to achieve accurate monitoring of easily condensing areas of the indoor unit, multiple monitoring points are deployed according to area: the first monitoring point is located on the surface of the indoor heat exchanger or in the heat exchange pipe area, for example, such as... Figure 4 As shown, along the airflow direction, three first monitoring points are respectively set between the fins or on the U-shaped heat exchange pipes of the left, middle, and right parts of the indoor heat exchanger 1 to monitor the heat exchange uniformity of the indoor heat exchanger 1. The first monitoring points are located at... Figure 4 The locations of A1, A2, and A3 are shown in the image. The second monitoring point is located inside the air duct and near the air inlet of the cross-flow fan blade. The airflow here is complex and prone to low temperatures due to disturbances. For example, the inner wall of the bottom casing 3 of the air conditioner forms a bottom air duct, and a second monitoring point is located within this bottom air duct along the axial direction of the cross-flow fan blade 2. The second monitoring point is located at... Figure 4 The location of B1 is shown. The third monitoring point is arranged in the air outlet or air guide plate area of ​​the air conditioner. For example, sensors are arranged on the upper edge of the air outlet and the inner side of the rotating shaft of the left and right air guide plates 4 to monitor the supply air temperature and the temperature of the air guide plates 4. The third monitoring point is located at... Figure 4 The locations of C1, C2, and C3.

[0075] The controller implements differentiated anti-condensation strategies for different areas based on the location of the target monitoring points and their corresponding condensation risk levels: When the condensation risk at the target monitoring point is Level 1, and the target monitoring point is the first monitoring point and / or the second monitoring point, it indicates that there is a slight low-temperature condensation trend in the heat exchanger area or the air inlet of the air duct. At this time, the first control strategy is implemented: the controller adjusts the operating parameters such as the rotation speed and operating frequency of the cross-flow fan blades according to the specific location of the target monitoring point. By increasing the airflow in the corresponding area, the local heat exchange and heat supply are enhanced, and the temperature is suppressed from further decreasing.

[0076] When the condensation risk at the target monitoring point is Level 1 and the target monitoring point is the third monitoring point, it indicates that there is a slight condensation risk in the air outlet or air guide plate area. At this time, the second control strategy is executed: the controller adjusts the air guide plate angle according to the location of the target monitoring point, and guides at least a part of the airflow from the air conditioner to directly blow on the easily condensing part, thereby increasing the local temperature and destroying the conditions for condensation formation.

[0077] In one optional implementation, the corresponding anti-condensation strategy is executed based on the location of the target monitoring point and the condensation risk level, and further includes: When the risk level of the target monitoring point is level two and the target monitoring point is located at the first monitoring point and / or the second monitoring point, the first control strategy and the third control strategy shall be used in synergistic control. When the risk level of the target monitoring point is level two and the target monitoring point is located at the third monitoring point, the second and third control strategies are used in synergistic control. The third control strategy includes adjusting the operating parameters of the refrigerant control component according to the superheat of the compressor's suction gas. The refrigerant control component includes at least an electronic expansion valve. The condensation risk of the first-level risk is lower than that of the second-level risk.

[0078] Specifically, condensation risk is divided into Level 1 risk and Level 2 risk. Level 1 risk is mild condensation risk, while Level 2 risk is moderate or higher condensation risk, which is a higher level of risk.

[0079] When the condensation risk level of the target monitoring point is level two, relying solely on a single control strategy is insufficient to quickly eliminate the hidden danger. Therefore, a multi-level strategy is adopted for coordinated control: when the target monitoring point is located at the first monitoring point in the indoor heat exchanger area, or the second monitoring point near the air inlet of the cross-flow fan, a combination of the first and third control strategies is used for coordinated control; when the target monitoring point is located at the third monitoring point in the air outlet area, a combination of the second and third control strategies is used for coordinated control. The third control strategy involves adjusting the refrigerant control components based on the compressor's suction superheat. These components include an electronic expansion valve, and its operating parameters include the opening degree of the electronic expansion valve. Alternatively, the refrigerant control components may also include a compressor, and its operating parameters include the compressor's operating frequency. By changing the refrigerant flow rate and system cooling capacity, the local supercooling is reduced at the source, and combined with airflow regulation, condensation is quickly suppressed.

[0080] In one optional implementation, the corresponding anti-condensation strategy is executed based on the location of the target monitoring point and the condensation risk level, and further includes: If the risk of condensation at the target monitoring point is not eliminated after the first control strategy ends, the first and third control strategies will be used in synergistic control. If the risk of condensation at the target monitoring point is not eliminated after the second control strategy ends, the second and third control strategies will be used in synergistic control. If the risk of condensation at the target monitoring point is not eliminated after the coordinated control of the first and third control strategies has ended, or after the coordinated control of the second and third control strategies has ended, a fourth control strategy shall be adopted for control. The fourth control strategy includes: providing auxiliary heating to the target monitoring point and / or adjusting the operating mode of the indoor fan.

[0081] Specifically, if the condensation risk is still not eliminated after implementing the corresponding anti-condensation strategy based on the location of the target monitoring point and the condensation risk level, the control measures will be further upgraded according to the following logic: If the target monitoring point still has a risk of condensation after the first control strategy is implemented, it indicates that the effect of simply adjusting the cross-flow fan blades to improve airflow is limited. In this case, the first control strategy and the third control strategy are upgraded to work together to optimize local airflow and adjust refrigerant components such as electronic expansion valves or compressors to reduce the degree of subcooling from the refrigeration system side.

[0082] If the risk of condensation still exists after implementing the second control strategy, the strategy will be upgraded to a coordinated control of the second and third control strategies. Based on the directional blowing of the air guide plate, the refrigerant system will be introduced to regulate the temperature and enhance the temperature control effect.

[0083] If the risk of condensation is still not eliminated after the above-mentioned airflow regulation and refrigerant system coordinated control, it indicates that it has reached an extremely stubborn operating condition. At this time, the highest level of the fourth control strategy is activated: auxiliary heating is provided to the area where the target monitoring point is located to directly raise the local temperature, and / or the indoor fan operation mode is adjusted (such as switching to intermittent air supply, disturbance air supply, etc.) to completely destroy the conditions for condensation formation and ensure that the risk is eliminated.

[0084] The first and second control strategies can be regarded as two anti-condensation sub-strategies in the first-level anti-condensation strategy. The combination of the first and third control strategies, as well as the combination of the second and third control strategies, can be regarded as two anti-condensation sub-strategies in the second-level anti-condensation strategy. The fourth anti-condensation strategy can be regarded as the highest level of anti-condensation strategy.

[0085] The following section provides a detailed introduction to the control strategies for target monitoring points in different regions under different risk levels, using specific examples.

[0086] In a specific example, combined Figure 5 The flowchart shows that if the target monitoring point is located on the right side of the evaporator (i.e., the area where the first monitoring point is located), and the internal fan is a dual-stage cross-flow fan motor with segmented windings or independent magnetic pole control, and the condensation risk level of the target monitoring point is detected to be Level 1, then the first control strategy (corresponding to...) is adopted. Figure 5 Strategy A) can be implemented by adjusting the proportion of the driving current of the right magnetic pole of the cross-flow fan blades, thereby increasing the speed or torque of the right blades and achieving a local increase in the right-side airflow speed. For example, while maintaining the overall average speed, the proportion of the driving current of the right magnetic pole of the cross-flow fan can be increased instantaneously, or the fan can be made to execute a "strong right-side blowing" mode (increasing the right-side airflow speed by 15-25%) twice a minute for 8 seconds each time, directly enhancing the airflow scouring of the target monitoring point on the right and improving its heat exchange efficiency.

[0087] If the target monitoring point is located in the upper left corner of the air outlet (i.e., the area where the third monitoring point is located), and if the condensation risk level of the target monitoring point is Level 1, then the second control strategy (corresponding to...) will be adopted. Figure 5 Strategy B in the above describes a method where the controller drives a stepper motor to precisely adjust and maintain the horizontal air guide within a 10° angle range deflected to the far left. Simultaneously, within this range, the air guide performs periodic micro-oscillations of ±5° (period 5 seconds), concentrating the airflow towards the target monitoring point for purging. The horizontal air guide is a type of air guide capable of oscillating left and right to adjust the airflow direction.

[0088] If the condensation risk level at the target monitoring point is level two, then in addition to the first or second control strategy, a third control strategy (corresponding to...) will be combined. Figure 5 Strategy C) is used for coordinated control. The third control strategy includes: when the compressor's suction superheat is high, it indicates insufficient refrigerant flow into the indoor heat exchanger, leading to low evaporation pressure and overall low evaporation temperature, further reducing the local temperature on the right side. If high superheat is accompanied by localized low temperatures, appropriately increasing the opening of the electronic expansion valve can increase the evaporation pressure and raise the evaporation temperature, helping to alleviate the localized low temperature. If the superheat is low, the electronic expansion valve should be avoided as much as possible to prevent a decrease in evaporation pressure and temperature, which would make the entire indoor heat exchanger surface colder and increase the risk of condensation. In this case, the first or second control strategy should be implemented simultaneously or preferentially to enhance heat exchange and raise the local temperature, offsetting the impact of the decreased evaporation temperature, or by increasing the internal fan speed to maintain safety and prevent condensation.

[0089] If the risk of condensation at the target monitoring point is not eliminated by combining one of the first and second control strategies with the third control strategy, then the fourth control strategy (corresponding to...) shall be adopted. Figure 5 The fourth control strategy involves adjusting the air conditioner according to strategy D). If each monitoring point of the air conditioner is equipped with an auxiliary heating unit, the fourth control strategy includes activating the auxiliary heating unit corresponding to the target monitoring point to provide auxiliary heating. For example, if the target monitoring point is located in the air duct or in the air outlet area, the corresponding miniature PTC heating element or air outlet grille heating strip is controlled to operate in low-power mode according to the specific location of the target monitoring point. This provides directional radiant heating to the local air duct wall or air outlet grille where the target monitoring point is located, rapidly increasing its surface temperature and directly eliminating condensation conditions at that location.

[0090] In other possible implementation methods, when the system identifies a condensation risk level of Level 1 at the same or adjacent locations in multiple consecutive monitoring cycles, or when the ambient humidity remains consistently high, the fourth adjustment strategy (corresponding to...) Figure 5 Strategy E also includes: switching the operating mode of the internal fan from a continuous "constant low speed operation" mode to a preset "intermittent operation" or "pre-dehumidification coupling" mode. For example, executing a cycle of "low speed ventilation for 3 minutes - shutdown (fan only running at a low speed) for 1 minute" periodically interrupts the continuous cooling supply to the low temperature point; or before entering the user-set low fan speed, running at a medium-high fan speed for 2-3 minutes to prioritize reducing the absolute humidity of the air, and then smoothly switching to the target low fan speed operation. In general, when the condensation risk level at the target monitoring point is Level 1, the first or second control strategy should be prioritized for precise intervention. When the condensation risk level at the target monitoring point is Level 2, a combination of "first control strategy + third control strategy" or "second control strategy + third control strategy" should be used for enhanced intervention. If the above combination is ineffective, the fourth control strategy should be gradually upgraded, and the intensity of the adjustment should be positively correlated with the absolute value of the temperature difference of the condensation risk at the target monitoring point.

[0091] In one alternative implementation, combined Figure 6 The flowchart illustrates that the anti-condensation method also includes: after the condensation risk at all target monitoring points is eliminated, exiting the anti-condensation mode and controlling the air conditioner to gradually restore the user-set original operating parameters. Specifically, the controller can control all actuators to gradually and in stages restore the system to the user's original settings to avoid new temperature fluctuations or impact on user experience caused by sudden adjustments. For example, if the system has executed the "right-side strong blowing" mode, the system does not stop immediately upon restoration. Instead, the fan speed increase percentage is gradually reduced (e.g., from +25% to +15%, running for 30 seconds; then to +5%, running for 30 seconds; finally returning to the original speed) to ensure a smooth transition of the airflow field.

When the one or more processors execute the program instructions, the one or more processors are used to implement the anti-condensation method provided above.

The communication bus 200 is configured to enable communication between these components.
