Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air conditioners, and particularly relates to an air conditioner control method and device, an air conditioner, a storage medium and a computer program product. BACKGROUND

[0002] In the whole life cycle operation process of a split air conditioning system, the condensate water of the indoor unit evaporator accumulates and is blown out with the air (condensation water blowing), which is a core reliability problem that has existed for a long time and has a high frequency of complaints. The condensation water blowing not only directly leads to a significant decline in the refrigeration capacity of the air conditioning system, but also greatly increases the evaporator heat transfer resistance when the condensate water accumulates on the evaporator surface, blocks the airflow channel, and reduces the air volume, resulting in a decrease in refrigeration efficiency. Moreover, it can cause serious harm to the indoor environment and equipment. After the condensate water leaks, it is easy to cause corrosive damage to the building envelope (such as walls and suspended ceilings), and it may also invade the indoor electrical equipment (such as sockets and electrical lines), causing potential safety hazards such as short circuits and electric leakage.

[0029] 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 in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] The problem of condensation and water runoff is characterized by significant delay and insidiousness: it usually only gradually appears in the later stages of the air conditioning equipment's service life, and is not easily noticed by users in the early stages. By the time it is discovered, irreversible damage to the equipment or the environment has often already occurred. The core causes of this problem can be summarized by the combined effect of two key mechanisms: first, refrigerant leakage leads to uneven distribution of refrigerant in the evaporator, which in turn causes an imbalance in the temperature field distribution on the evaporator surface, resulting in excessively low temperatures in some areas that cause abnormal accumulation of condensate; second, the hydrophilicity of the evaporator fins deteriorates due to dust accumulation and other factors during long-term use, preventing condensate from flowing smoothly down the fins, further aggravating the accumulation phenomenon, and ultimately causing the condensate to exceed the carrying capacity of the conventional drainage path and be carried out by the airflow from the outlet.

[0031] To address the condensation and water blowing problem, existing technologies primarily focus on two main approaches, but both suffer from unavoidable drawbacks: some solutions monitor parameters such as outlet air temperature and air guide plate temperature, dynamically reducing compressor operating frequency or increasing the opening of the electronic expansion valve to suppress condensation. However, these solutions essentially sacrifice the air conditioner's cooling capacity, inevitably causing fluctuations in the indoor temperature field and severely reducing user comfort. Other solutions adjust the water collection tray structure and air guide plate control path to block condensate from blowing out, but actual test data shows that air guide plate obstruction of the air outlet leads to a cooling capacity reduction of over 30%, and obstructed airflow easily exacerbates uneven evaporator temperature distribution, inducing frosting / icing faults. Furthermore, the movement of mechanical components and air outlet obstruction generate additional noise, further harming the user experience. In summary, all existing technologies sacrifice air conditioning system energy efficiency or user comfort, failing to fundamentally solve the condensation and water blowing problem.

[0032] Therefore, this invention provides a control method for preventing condensation and water blowing in air conditioners. It constructs a multimodal sensing system through an infrared optical sensing unit to achieve early warning of condensation and water blowing risks; it uses an ultrasonic transducer to instantly atomize the condensate into an aerosol and discharge it, blocking the water blowing path; and it relies on the synergy of infrared and ultrasonic to form a closed-loop control across the entire chain, eliminating the condensation and water blowing problem without changing the air conditioner's operating parameters and indoor airflow, thereby improving the system's energy efficiency ratio. At the same time, it breaks through the blind spot of equipment operating status perception, and simultaneously improves system reliability and user comfort.

[0033] According to an embodiment of the present invention, a control method for an air conditioner is provided. The air conditioner includes a condensate detection component and a condensate treatment component. The condensate detection component is used to collect condensate state information on the surface of the indoor heat exchanger of the air conditioner. The condensate state information reflects the degree of condensate accumulation and includes the condensate distribution density and accumulation thickness. The distribution density is the amount of condensate distributed per unit area, and the accumulation thickness is the vertical height formed by the accumulation of condensate on the surface of the indoor heat exchanger. The condensate treatment component is used to treat the condensate accumulated on the surface of the indoor heat exchanger, converting the condensate into water mist that can flow with the airflow of the air conditioning duct, thus preventing the condensate from being discharged in liquid form with the air outlet. The surface of the indoor heat exchanger is divided into multiple independent monitoring areas, specifically multiple non-overlapping areas divided into the surface of the indoor heat exchanger according to certain rules. Each area can be used as an independent monitoring unit to determine the degree of condensate accumulation in that area for targeted treatment.

[0034] like Figure 1 The flowchart of an embodiment of the method of the present invention is shown. The air conditioner control method may include steps S110 to S140.

[0035] In step S110, during the air conditioner's cooling operation, the temperature and humidity in the indoor unit of the air conditioner, the condensate status information collected by the condensate detection component, and the surface temperature of the indoor heat exchanger are acquired.

[0036] Temperature and humidity are the basic environmental parameters for determining whether condensation is likely to occur in an indoor heat exchanger, and can further assess the risk of condensation. Condensation status information directly reflects the actual accumulation of condensation on the surface of the indoor heat exchanger, and is the core basis for subsequently determining the target area and activating the treatment components.

[0037] Specifically, after the air conditioner is turned on, the sensors built into the indoor unit continuously collect temperature and humidity data of the indoor environment; at the same time, the condensate detection component collects the condensate distribution density and accumulation thickness on the surface of the indoor heat exchanger at a set frequency to form condensate status information.

[0038] In step S120, it is determined whether there is a risk of condensation in the indoor heat exchanger based on the temperature, humidity, and surface temperature.

[0039] The formation of condensate requires the physical condition of "water vapor in the air condensing upon cooling." When the indoor air temperature drops below the dew point temperature, water vapor in the air will condense into liquid water on low-temperature surfaces (such as the surface of an indoor heat exchanger). The dew point temperature is determined by both the indoor air temperature and relative humidity. Therefore, the dew point temperature can be calculated using temperature and humidity, allowing us to determine whether the surface of the indoor heat exchanger is likely to reach this temperature and generate condensate, thus identifying the risk of condensation. If there is no risk of condensation, no further condensate monitoring and treatment are needed, reducing unnecessary energy consumption; if there is a risk, further monitoring of condensation accumulation is required.

[0040] In some implementations, step S120, determining whether the indoor heat exchanger has a condensation risk based on the temperature, humidity, and surface temperature, includes: calculating the dew point temperature based on the temperature and humidity; determining the relationship between the surface temperature and the dew point temperature; if the surface temperature is less than the dew point temperature, determining that the indoor heat exchanger has a condensation risk; if the surface temperature is greater than or equal to the dew point temperature, determining that the indoor heat exchanger does not have a condensation risk.

[0041] Specifically, according to the preset dew point temperature calculation algorithm, the temperature and humidity values ​​are substituted into the algorithm formula to calculate the specific value of the current indoor air dew point temperature. The current indoor heat exchanger surface temperature is directly compared with the dew point temperature. If the result is that the temperature is lower than the dew point temperature, it is determined that there is a risk of condensation on the indoor heat exchanger. If the result is that the surface temperature is greater than or equal to the dew point temperature, it is determined that there is no risk of condensation on the indoor heat exchanger. At this time, there is no need to enter the subsequent condensate monitoring and treatment stage. The air conditioner is simply kept in normal operation, and temperature and humidity data are repeatedly acquired at the set frequency to recalculate the dew point temperature and assess the risk, ensuring timely detection of risk changes.

[0042] The preset dew point temperature calculation algorithm is as follows: Where T is the air temperature and RH is the relative humidity. d This is the dew point temperature.

[0043] In step S130, if it is determined that there is a risk of condensation in the indoor heat exchanger, a target area for condensate accumulation is determined from the independent monitoring area; wherein, the independent monitoring area where the degree of condensate accumulation is greater than or equal to a preset threshold is determined as the target area.

[0044] Even with the risk of condensation, the degree of condensate accumulation may vary across different areas of the indoor heat exchanger surface. Treating the entire surface uniformly would waste energy and could cause unnecessary intervention in areas without significant accumulation. Dividing the heat exchanger surface into independent monitoring areas and identifying only those exceeding a threshold as target areas allows for "precise positioning and on-demand treatment," reducing energy consumption and improving the economic efficiency of air conditioning operation while ensuring effective treatment. The degree of condensate accumulation refers to the extent of condensate buildup on the indoor heat exchanger surface, reflected by the distribution density and accumulation thickness collected by condensate detection components.

[0045] Specifically, if a condensation risk is determined, the condensation status information of each independent monitoring area collected by the condensation detection component will be retrieved, and the degree of condensation accumulation in each area will be calculated. Subsequently, the degree of accumulation in each area will be compared with a preset threshold one by one. Independent monitoring areas with an accumulation degree greater than or equal to the preset threshold will be marked as target areas for condensation accumulation, and the location information of these target areas (such as area number, coordinates, etc.) will be recorded to provide a location basis for the subsequent activation of the treatment component.

[0046] In some implementations, step S130, determining the target area for condensate accumulation from the independent monitoring areas, includes: sampling and testing each of the independent monitoring areas to determine a sampling area; determining whether the degree of condensate accumulation in the sampling area is greater than or equal to a preset threshold; if the degree of condensate accumulation in the sampling area is greater than or equal to the preset threshold, then determining the sampling area as the target area, and simultaneously testing the adjacent independent monitoring areas of the sampling area to determine whether the adjacent independent monitoring areas are the target areas.

[0047] Sampling inspection refers to the operation of selecting a portion of all independent monitoring areas according to preset selection rules to test the degree of condensation accumulation, rather than testing all independent monitoring areas one by one. The aim is to reduce the consumption of testing resources and testing time while ensuring monitoring effectiveness. The sampling area refers to a specific independent monitoring area selected through sampling inspection to represent a portion of the independent monitoring areas for condensation accumulation testing. The test results of this area are the core basis for determining whether the testing scope needs to be expanded. Adjacent independent monitoring areas refer to independent monitoring areas that are directly adjacent to the sampling area in terms of spatial location. Since condensation may diffuse or accumulate continuously between adjacent areas, testing these areas can avoid missing adjacent high-risk accumulation areas.

[0048] Inspecting every individual monitoring area on the surface of the indoor heat exchanger would consume significant time and resources, especially when there are many areas. This could lead to delays in feedback on condensate accumulation, affecting the timeliness of processing. Sampling inspection, selecting representative areas (such as those distributed across different locations on the heat exchanger), allows for rapid identification of the overall trend of condensate accumulation while reducing unnecessary inspections, balancing efficiency and resource consumption. When the accumulation level in a sampled area reaches a preset threshold, that area already requires treatment and should be directly identified as the target area. Simultaneously, condensate on the surface of the indoor heat exchanger may diffuse to adjacent areas due to gravity, airflow, or other factors, or exhibit "patchy accumulation" characteristics. Adjacent areas are also likely to have a high risk of accumulation. Therefore, supplementing the inspection of adjacent areas allows for precise location and expanded coverage, ensuring no area requiring treatment is missed.

[0049] Specifically, according to a preset sampling rule (e.g., selecting one area every three independent monitoring areas, and selecting two areas each from the upper, middle, and lower parts of the heat exchanger), a portion of the areas are selected as sampling areas from all independent monitoring areas. Subsequently, condensate status information is collected from these sampling areas using a condensate detection component to obtain condensate accumulation data for each sampling area. The accumulation degree of each sampling area is compared with a preset threshold to determine whether the accumulation degree of each sampling area meets the condition of "greater than or equal to the preset threshold," and the comparison results are recorded. For sampling areas determined to have an accumulation level ≥ a preset threshold, these areas are first marked as target areas. Then, the spatial location of this sampling area on the surface of the indoor heat exchanger is determined, and all independent monitoring areas directly adjacent to it are selected. Condensate state information from these adjacent areas is collected using a condensate detection component, and the accumulation level is calculated and compared with a preset threshold. If the accumulation level of an adjacent area is ≥ the preset threshold, that adjacent area is also marked as a target area; if the accumulation level is < the preset threshold, it is not marked as a target area. This process is repeated until all adjacent areas of the sampling areas with accumulation levels ≥ the threshold have been detected and determined. This achieves accurate and efficient positioning of the target areas.

[0050] In step S140, the condensate treatment unit is activated to treat the condensate in the target area.

[0051] Activating the condensate treatment unit treats the target area, converting condensate into water mist that can flow with the airflow in the duct. This mist is then properly discharged or returned to the room through the duct system, fundamentally blocking the path of condensate blow-off and ensuring the normal operation of the air conditioner and the safety of the indoor environment.

[0052] Specifically, based on the recorded target area location information, a start command is sent to the condensate treatment component, and the location parameters of the target area are transmitted synchronously. After receiving the command and parameters, the condensate treatment component adjusts its working position or working range (such as aligning with the target area), and then starts the working mechanism to treat the condensate accumulated on the surface of the target area, converting the liquid condensate into water mist. During the treatment process, the condensate status information of the target area can be received in real time from the condensate detection component to judge the treatment effect until the condensate accumulation level in the target area is lower than the preset threshold.

[0053] This invention first assesses the risk of condensation and then monitors the accumulation in a targeted manner, avoiding ineffective monitoring when there is no risk and reducing air conditioning energy consumption. By dividing the area into independent monitoring zones and only processing target areas where the accumulation exceeds the threshold, it achieves on-demand processing, avoiding energy waste caused by overall processing. At the same time, it precisely blocks the path of condensate water discharged with the air outlet, effectively solving the problem of condensation and water blowing, ensuring the safety of indoor equipment and building structure, and improving the comfort of users when using air conditioning.

[0054] For example, the surface of the indoor heat exchanger of the air conditioner indoor unit is divided into 6 independent monitoring areas (numbered A1-A6); the configured condensate detection component can move on the surface of the heat exchanger to collect the condensate distribution density and accumulation thickness in each area; the condensate treatment component is an atomizing device that can be precisely aimed at the target area, with preset thresholds set as "distribution density (the ratio of the area of ​​the condensate accumulation area to the area of ​​the corresponding independent monitoring area) ≥ 20%, accumulation thickness ≥ 1mm"; in cooling mode, after the air conditioner is started, the indoor unit sensor collects an indoor temperature of 28℃ and a relative humidity of 70%; substituting the temperature of 28℃ and the relative humidity of 70% into the dew point temperature algorithm, the dew point temperature is calculated to be 22℃, and at the same time, the surface temperature of the indoor heat exchanger is collected as 18℃. The temperature was below ℃ (below the dew point temperature of 22℃), indicating a risk of condensation. The condensate detection unit then collected condensate status information from areas A1-A6 (A2 area had a distribution density of 22% and an accumulation thickness of 1.1mm, A3 area had a distribution density of 25% and an accumulation thickness of 1.3mm, and the remaining areas were all below the threshold). The degree of accumulation in each area was calculated, and it was found that the accumulation degrees in areas A2 and A3 were both greater than the preset threshold, thus A2 and A3 were identified as target areas. A command was sent to the condensate treatment unit to process areas A2 and A3. The treatment unit activated the atomization function on areas A2 and A3, converting the condensate into water mist. The water mist was then discharged with the airflow from the air conditioning duct, preventing the accumulation of condensate in areas A2 and A3 from being blown out.

[0055] In some embodiments, the condensate detection component is an infrared detection component, which can move along the surface of the indoor heat exchanger to cover each of the independent monitoring areas on the surface of the indoor heat exchanger; the condensate treatment component is an ultrasonic treatment component, which, when activated, converts the condensate in the target area into water mist that can flow with the airflow of the air conditioning duct through ultrasonic vibration.

[0056] Moving the infrared detection component along the surface of the heat exchanger ensures that it reaches each independent monitoring area, collecting condensate status information from all areas. This achieves comprehensive monitoring without blind spots, providing complete data for accurate determination of target areas and avoiding processing omissions due to incomplete monitoring.

[0057] Specifically, after the air conditioner enters the condensate monitoring stage, the infrared detection component begins to move according to the preset moving path, and arrives at each independent monitoring area in sequence; it stays in each independent monitoring area for a preset time to collect data on the condensate distribution density and accumulation thickness of that area; after the data collection is completed, it continues to move to the next independent monitoring area until the information of all independent monitoring areas has been collected, and all the data are summarized to determine the degree of condensate accumulation in each area.

[0058] Ultrasonic vibration can generate a cavitation effect, which instantly breaks down liquid condensate into micron-sized water mist. These water mist particles are so small that they can flow with the airflow in the air conditioning duct, which can prevent liquid water from being blown out and will not affect the normal air output and cooling effect of the air conditioner. At the same time, ultrasonic treatment does not require changing the air conditioner's operating parameters and will not sacrifice cooling capacity or user comfort.

[0059] Specifically, once the target area is determined, the ultrasonic processing component is activated. Based on the location information of the target area, the ultrasonic processing component adjusts its working range and then generates ultrasonic vibrations. These vibrations act on the liquid condensate in the target area, causing it to break down into micron-sized water mist under cavitation. Driven by the airflow in the air conditioning duct, these water mists are either discharged from the air outlet or returned to the indoor environment, completing the treatment of the condensate in the target area. During the treatment process, the infrared detection component can again collect information on the state of the condensate in the target area to determine the treatment effect.

[0060] In some embodiments, the air conditioner further includes an image sensing component; when acquiring the condensate status information, the image sensing component also collects image information of the indoor heat exchanger surface, and combines image analysis algorithms to assist the infrared detection component in determining the degree of condensate accumulation on the indoor heat exchanger surface.

[0061] Image information acquired by image sensing components can intuitively present the distribution pattern (such as continuous sheets or scattered dots) and coverage area of ​​condensate on the heat exchanger surface. Image analysis algorithms can quantify these image features (such as calculating the pixel ratio of the condensate area). By combining the quantification results with the distribution density and accumulation thickness data acquired by infrared detection components, the actual accumulation of condensate can be cross-verified, avoiding misjudgments caused by single data deviations.

[0062] Specifically, while the infrared detection component moves along the surface of the indoor heat exchanger to collect condensate status information in each independent monitoring area, the image sensing component simultaneously collects surface images of the corresponding area. The collected image information is input into an image analysis algorithm. The algorithm, based on preset judgment rules (such as "areas with gray values ​​below a preset gray value threshold in the image are judged as condensate areas"), calculates the coverage area and distribution pattern of condensate in each independent monitoring area and outputs condensate distribution data at the image level. This data is then correlated with the distribution density and accumulation thickness data collected by the infrared detection component. If the condensate accumulation trends reflected by both are consistent (such as both showing a high degree of accumulation in a certain area), the data from the infrared detection component is used as the core to determine the degree of condensate accumulation in that area. If there is a significant difference between the two (such as infrared detection showing a high degree of accumulation, but image analysis showing no condensate characteristics), the infrared data and image information of that area are re-collected and analyzed again until the trends are consistent or the cause of the deviation is clarified (such as confirming that the infrared detection is interfered with by dust accumulation), and finally the accurate degree of condensate accumulation is determined.

[0063] The infrared detection component, image sensing component, and ultrasonic processing component are arranged as follows: Figures 3 to 5 As shown, the infrared detection component is an infrared optical sensor 4, the image sensing component is an image sensor 5, and the ultrasonic processing component includes an ultrasonic transducer probe 6, an ultrasonic generator 7, and a telescopic rod 8.

[0064] An infrared optical sensor 4 is installed near the evaporator, preferably directly above or to the side of the evaporator. It can also be configured to move along a fixed path on the upper or lower surface of the evaporator to detect the formation and accumulation of condensate on the evaporator surface in real time. The movement of the infrared optical sensor 4 relies on a horizontal guide rail 1 and a vertical guide rail 2 mounted on the bottom casing of the air conditioner unit. The horizontal guide rail can move back and forth on the vertical guide rail using a single motor and hinge, and similarly, it can reciprocate back and forth on the horizontal rail. Two small motors combined with hinges within the guide rails enable two-dimensional movement of the sensor on the evaporator surface, thus providing full-range monitoring signal coverage of the evaporator surface. The infrared optical sensor 4 consists of an infrared light source and an infrared receiver. The infrared sensor wavelength is 3-5μm (the specific absorption peak of water molecules). Due to the strong absorption characteristics of water molecules to infrared light, it can directly and accurately identify condensate accumulation on the evaporator surface without waiting for temperature changes, determining the distribution density and thickness of the condensate.

[0065] Infrared optical sensor 4, image sensor 5, and ultrasonic transducer probe 6 are integrated in a horizontal guide rail located above the evaporator and can move synchronously. After the ultrasonic processing unit is activated, the telescopic rod 8 extends, inserting the ultrasonic transducer probe 6 into the accumulated condensate. At this time, the ultrasonic generator 7 works, and the probe releases a microcurrent. Once a circuit is formed (indicating that the probe is immersed in the condensate), the probe is powered on and starts to disperse the condensate into micron-sized water mist. The water mist is then discharged from the air outlet by the airflow driven by the internal fan. The ultrasonic processing unit utilizes the inverse piezoelectric effect. After high-frequency alternating current is conducted to the ceramic plate through metal electrodes, the ceramic lattice deforms, causing periodic deformation. At this time, the probe vibrates (1.7~2.4MHz) and transmits it to the accumulated condensate, triggering a cavitation effect. The water body generates a large number of extremely small bubbles that continuously burst, thereby breaking the condensate into 1~10μm water mist.

[0066] Figure 6 A flowchart illustrating the control method for preventing condensation and blowing water in air conditioners, including steps 1 to 4.

[0067] Step 1: Divide the indoor heat exchanger into equal-area sections A1, A2~A1. n In the same region, n is a multiple of 3 or 4. After the air conditioner enters cooling mode, the indoor unit's airflow temperature T1 and humidity H1 are detected every 300 seconds, and the risk of condensation is determined based on T1 and H1.

[0068] Step 2: Once the risk of condensation is confirmed, the infrared optical sensor for condensate water is activated to conduct random checks on a preset area of ​​the evaporator. One area will be randomly selected from every 3 or 4 rectangular areas as sample A. x To determine whether the area of ​​condensate accumulation in the sampled area exceeds 20%.

[0069] Step 3, if A x If the area of ​​condensate accumulation exceeds 20%, increase the sampling area and check A. x Adjacent A x+1 Area and A x-1 The area is used to determine whether the area where condensate accumulates exceeds 20%.

[0070] Step 4: After identifying all areas where condensate accumulation exceeds 20%, mark these areas and activate the ultrasonic transducer probe to remove the accumulated condensate in the marked areas. Once the condensate accumulation in one area falls below 5%, move on to the next marked area and continue until all marked areas have been treated.

[0071] The air conditioner using the technical solution of this embodiment includes a condensate detection component, a condensate treatment component, and an indoor heat exchanger whose surface is divided into multiple independent monitoring areas. The condensate detection component collects condensate state information on the surface of the indoor heat exchanger, reflecting the degree of condensate accumulation. The condensate treatment component converts the condensate accumulated on the surface of the indoor heat exchanger into water mist that can flow with the airflow in the duct. When the air conditioner is cooling, it determines whether there is a risk of condensation on the indoor heat exchanger based on the temperature and humidity in the indoor unit. If a risk exists, the independent monitoring area where the degree of condensate accumulation reaches a preset threshold is identified as the target area. The condensate treatment component is activated to treat the condensate in the target area. This effectively prevents condensation and water blowing during air conditioning cooling.

[0072] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method of an air conditioner is also provided. The air conditioner includes a condensate detection component and a condensate treatment component; the condensate detection component is used to collect condensate state information on the surface of the indoor heat exchanger of the air conditioner, the condensate state information reflecting the degree of condensate accumulation, the condensate state information including the condensate distribution density and accumulation thickness, the distribution density being the amount of condensate distributed per unit area, and the accumulation thickness being the vertical height formed by the accumulation of condensate on the surface of the indoor heat exchanger; the condensate treatment component is used to treat the condensate accumulated on the surface of the indoor heat exchanger, converting the condensate into water mist that can flow with the airflow of the air conditioning duct, preventing the condensate from being discharged in liquid form with the air outlet; the surface of the indoor heat exchanger is divided into multiple independent monitoring areas, specifically referring to multiple non-overlapping areas divided into the surface of the indoor heat exchanger according to certain rules, each area can be used as an independent monitoring unit to individually determine the degree of condensate accumulation in that area for targeted treatment.

[0073] See Figure 2 The diagram shows a structural schematic of an embodiment of the device of the present invention. The control device of the air conditioner may include: an acquisition unit 102 and a control unit 104.

[0074] The acquisition unit 102 is configured to acquire the temperature and humidity in the indoor unit of the air conditioner, the condensate status information collected by the condensate detection component, and the surface temperature of the indoor heat exchanger during air conditioner cooling operation. For the specific functions and processing of this acquisition unit 102, please refer to step S110.

[0075] Temperature and humidity are the basic environmental parameters for determining whether condensation is likely to occur in an indoor heat exchanger, and can further assess the risk of condensation. Condensation status information directly reflects the actual accumulation of condensation on the surface of the indoor heat exchanger, and is the core basis for subsequently determining the target area and activating the treatment components.

[0076] Specifically, after the air conditioner is turned on, the sensors built into the indoor unit continuously collect temperature and humidity data of the indoor environment; at the same time, the condensate detection component collects the condensate distribution density and accumulation thickness on the surface of the indoor heat exchanger at a set frequency to form condensate status information.

[0077] Control unit 104 is configured to determine whether there is a risk of condensation on the indoor heat exchanger based on the temperature, humidity, and surface temperature. The specific functions and processing of control unit 104 are described in step S120.

[0078] The formation of condensate requires the physical condition of "water vapor in the air condensing upon cooling." When the indoor air temperature drops below the dew point temperature, water vapor in the air will condense into liquid water on low-temperature surfaces (such as the surface of an indoor heat exchanger). The dew point temperature is determined by both the indoor air temperature and relative humidity. Therefore, the dew point temperature can be calculated using temperature and humidity, allowing us to determine whether the surface of the indoor heat exchanger is likely to reach this temperature and generate condensate, thus identifying the risk of condensation. If there is no risk of condensation, no further condensate monitoring and treatment are needed, reducing unnecessary energy consumption; if there is a risk, further monitoring of condensation accumulation is required.

[0079] In some embodiments, the control unit 104 determines whether there is a risk of condensation on the indoor heat exchanger based on the temperature, the humidity, and the surface temperature, including: calculating the dew point temperature based on the temperature and the humidity; determining the relationship between the surface temperature and the dew point temperature; if the surface temperature is less than the dew point temperature, determining that there is a risk of condensation on the indoor heat exchanger; if the surface temperature is greater than or equal to the dew point temperature, determining that there is no risk of condensation on the indoor heat exchanger.

[0080] Specifically, according to the preset dew point temperature calculation algorithm, the temperature and humidity values ​​are substituted into the algorithm formula to calculate the specific value of the current indoor air dew point temperature. The current indoor heat exchanger surface temperature is directly compared with the dew point temperature. If the result is that the temperature is lower than the dew point temperature, it is determined that there is a risk of condensation on the indoor heat exchanger. If the result is that the surface temperature is greater than or equal to the dew point temperature, it is determined that there is no risk of condensation on the indoor heat exchanger. At this time, there is no need to enter the subsequent condensate monitoring and treatment stage. The air conditioner is simply kept in normal operation, and temperature and humidity data are repeatedly acquired at the set frequency to recalculate the dew point temperature and assess the risk, ensuring timely detection of risk changes.

[0081] The preset dew point temperature calculation algorithm is as follows: Where T is the air temperature and RH is the relative humidity. d This is the dew point temperature.

[0082] The control unit 104 is further configured to determine a target area for condensate accumulation from the independent monitoring areas if it is determined that there is a risk of condensation on the indoor heat exchanger; wherein, the independent monitoring areas where the degree of condensate accumulation is greater than or equal to a preset threshold are determined as the target area. The specific functions and processing of this control unit 104 are described in step S130.

[0083] Even with the risk of condensation, the degree of condensate accumulation may vary across different areas of the indoor heat exchanger surface. Treating the entire surface uniformly would waste energy and could cause unnecessary intervention in areas without significant accumulation. Dividing the heat exchanger surface into independent monitoring areas and identifying only those exceeding a threshold as target areas allows for "precise positioning and on-demand treatment," reducing energy consumption and improving the economic efficiency of air conditioning operation while ensuring effective treatment. The degree of condensate accumulation refers to the extent of condensate buildup on the indoor heat exchanger surface, reflected by the distribution density and accumulation thickness collected by condensate detection components.

[0084] Specifically, if a condensation risk is determined, the condensation status information of each independent monitoring area collected by the condensation detection component will be retrieved, and the degree of condensation accumulation in each area will be calculated. Subsequently, the degree of accumulation in each area will be compared with a preset threshold one by one. Independent monitoring areas with an accumulation degree greater than or equal to the preset threshold will be marked as target areas for condensation accumulation, and the location information of these target areas (such as area number, coordinates, etc.) will be recorded to provide a location basis for the subsequent activation of the treatment component.

[0085] In some embodiments, the control unit 104 determines the target area for condensate accumulation from the independent monitoring areas, including: sampling and detecting each of the independent monitoring areas to determine a sampling area; determining whether the degree of condensate accumulation in the sampling area is greater than or equal to a preset threshold; if the degree of condensate accumulation in the sampling area is greater than or equal to the preset threshold, then determining the sampling area as the target area, and simultaneously detecting the adjacent independent monitoring areas of the sampling area to determine whether the adjacent independent monitoring areas are the target areas.

[0086] Sampling inspection refers to the operation of selecting a portion of all independent monitoring areas according to preset selection rules to test the degree of condensation accumulation, rather than testing all independent monitoring areas one by one. The aim is to reduce the consumption of testing resources and testing time while ensuring monitoring effectiveness. The sampling area refers to a specific independent monitoring area selected through sampling inspection to represent a portion of the independent monitoring areas for condensation accumulation testing. The test results of this area are the core basis for determining whether the testing scope needs to be expanded. Adjacent independent monitoring areas refer to independent monitoring areas that are directly adjacent to the sampling area in terms of spatial location. Since condensation may diffuse or accumulate continuously between adjacent areas, testing these areas can avoid missing adjacent high-risk accumulation areas.

[0087] Inspecting every individual monitoring area on the surface of the indoor heat exchanger would consume significant time and resources, especially when there are many areas. This could lead to delays in feedback on condensate accumulation, affecting the timeliness of processing. Sampling inspection, selecting representative areas (such as those distributed across different locations on the heat exchanger), allows for rapid identification of the overall trend of condensate accumulation while reducing unnecessary inspections, balancing efficiency and resource consumption. When the accumulation level in a sampled area reaches a preset threshold, that area already requires treatment and should be directly identified as the target area. Simultaneously, condensate on the surface of the indoor heat exchanger may diffuse to adjacent areas due to gravity, airflow, or other factors, or exhibit "patchy accumulation" characteristics. Adjacent areas are also likely to have a high risk of accumulation. Therefore, supplementing the inspection of adjacent areas allows for precise location and expanded coverage, ensuring no area requiring treatment is missed.

[0088] Specifically, according to a preset sampling rule (e.g., selecting one area every three independent monitoring areas, and selecting two areas each from the upper, middle, and lower parts of the heat exchanger), a portion of the areas are selected as sampling areas from all independent monitoring areas. Subsequently, condensate status information is collected from these sampling areas using a condensate detection component to obtain condensate accumulation data for each sampling area. The accumulation degree of each sampling area is compared with a preset threshold to determine whether the accumulation degree of each sampling area meets the condition of "greater than or equal to the preset threshold," and the comparison results are recorded. For sampling areas determined to have an accumulation level ≥ a preset threshold, these areas are first marked as target areas. Then, the spatial location of this sampling area on the surface of the indoor heat exchanger is determined, and all independent monitoring areas directly adjacent to it are selected. Condensate state information from these adjacent areas is collected using a condensate detection component, and the accumulation level is calculated and compared with a preset threshold. If the accumulation level of an adjacent area is ≥ the preset threshold, that adjacent area is also marked as a target area; if the accumulation level is < the preset threshold, it is not marked as a target area. This process is repeated until all adjacent areas of the sampling areas with accumulation levels ≥ the threshold have been detected and determined. This achieves accurate and efficient positioning of the target areas.

[0089] The control unit 104 is also configured to activate the condensate treatment component to treat the condensate in the target area. The specific functions and processing of the control unit 104 are described in step S140.

[0090] Activating the condensate treatment unit treats the target area, converting condensate into water mist that can flow with the airflow in the duct. This mist is then properly discharged or returned to the room through the duct system, fundamentally blocking the path of condensate blow-off and ensuring the normal operation of the air conditioner and the safety of the indoor environment.

[0091] Specifically, based on the recorded target area location information, a start command is sent to the condensate treatment component, and the location parameters of the target area are transmitted synchronously. After receiving the command and parameters, the condensate treatment component adjusts its working position or working range (such as aligning with the target area), and then starts the working mechanism to treat the condensate accumulated on the surface of the target area, converting the liquid condensate into water mist. During the treatment process, the condensate status information of the target area can be received in real time from the condensate detection component to judge the treatment effect until the condensate accumulation level in the target area is lower than the preset threshold.

[0092] This invention first assesses the risk of condensation and then monitors the accumulation in a targeted manner, avoiding ineffective monitoring when there is no risk and reducing air conditioning energy consumption. By dividing the area into independent monitoring zones and only processing target areas where the accumulation exceeds the threshold, it achieves on-demand processing, avoiding energy waste caused by overall processing. At the same time, it precisely blocks the path of condensate water discharged with the air outlet, effectively solving the problem of condensation and water blowing, ensuring the safety of indoor equipment and building structure, and improving the comfort of users when using air conditioning.

[0093] For example, the surface of the indoor heat exchanger of the air conditioner indoor unit is divided into 6 independent monitoring areas (numbered A1-A6); the configured condensate detection component can move on the surface of the heat exchanger to collect the condensate distribution density and accumulation thickness in each area; the condensate treatment component is an atomizing device that can be precisely aimed at the target area, with preset thresholds set as "distribution density (the ratio of the area of ​​the condensate accumulation area to the area of ​​the corresponding independent monitoring area) ≥ 20%, accumulation thickness ≥ 1mm"; in cooling mode, after the air conditioner is started, the indoor unit sensor collects an indoor temperature of 28℃ and a relative humidity of 70%; substituting the temperature of 28℃ and the relative humidity of 70% into the dew point temperature algorithm, the dew point temperature is calculated to be 22℃, and at the same time, the surface temperature of the indoor heat exchanger is collected as 18℃. The temperature was below ℃ (below the dew point temperature of 22℃), indicating a risk of condensation. The condensate detection unit then collected condensate status information from areas A1-A6 (A2 area had a distribution density of 22% and an accumulation thickness of 1.1mm, A3 area had a distribution density of 25% and an accumulation thickness of 1.3mm, and the remaining areas were all below the threshold). The degree of accumulation in each area was calculated, and it was found that the accumulation degrees in areas A2 and A3 were both greater than the preset threshold, thus A2 and A3 were identified as target areas. A command was sent to the condensate treatment unit to process areas A2 and A3. The treatment unit activated the atomization function on areas A2 and A3, converting the condensate into water mist. The water mist was then discharged with the airflow from the air conditioning duct, preventing the accumulation of condensate in areas A2 and A3 from being blown out.

[0094] In some embodiments, the condensate detection component is an infrared detection component, which can move along the surface of the indoor heat exchanger to cover each of the independent monitoring areas on the surface of the indoor heat exchanger; the condensate treatment component is an ultrasonic treatment component, which, when activated, converts the condensate in the target area into water mist that can flow with the airflow of the air conditioning duct through ultrasonic vibration.

[0095] Moving the infrared detection component along the surface of the heat exchanger ensures that it reaches each independent monitoring area, collecting condensate status information from all areas. This achieves comprehensive monitoring without blind spots, providing complete data for accurate determination of target areas and avoiding processing omissions due to incomplete monitoring.

[0096] Specifically, after the air conditioner enters the condensate monitoring stage, the infrared detection component begins to move according to the preset moving path, and arrives at each independent monitoring area in sequence; it stays in each independent monitoring area for a preset time to collect data on the condensate distribution density and accumulation thickness of that area; after the data collection is completed, it continues to move to the next independent monitoring area until the information of all independent monitoring areas has been collected, and all the data are summarized to determine the degree of condensate accumulation in each area.

[0097] Ultrasonic vibration can generate a cavitation effect, which instantly breaks down liquid condensate into micron-sized water mist. These water mist particles are so small that they can flow with the airflow in the air conditioning duct, which can prevent liquid water from being blown out and will not affect the normal air output and cooling effect of the air conditioner. At the same time, ultrasonic treatment does not require changing the air conditioner's operating parameters and will not sacrifice cooling capacity or user comfort.

[0098] Specifically, once the target area is determined, the ultrasonic processing component is activated. Based on the location information of the target area, the ultrasonic processing component adjusts its working range and then generates ultrasonic vibrations. These vibrations act on the liquid condensate in the target area, causing it to break down into micron-sized water mist under cavitation. Driven by the airflow in the air conditioning duct, these water mists are either discharged from the air outlet or returned to the indoor environment, completing the treatment of the condensate in the target area. During the treatment process, the infrared detection component can again collect information on the state of the condensate in the target area to determine the treatment effect.

[0099] In some embodiments, the air conditioner further includes an image sensing component; when acquiring the condensate status information, the image sensing component also collects image information of the indoor heat exchanger surface, and combines image analysis algorithms to assist the infrared detection component in determining the degree of condensate accumulation on the indoor heat exchanger surface.

[0100] Image information acquired by image sensing components can intuitively present the distribution pattern (such as continuous sheets or scattered dots) and coverage area of ​​condensate on the heat exchanger surface. Image analysis algorithms can quantify these image features (such as calculating the pixel ratio of the condensate area). By combining the quantification results with the distribution density and accumulation thickness data acquired by infrared detection components, the actual accumulation of condensate can be cross-verified, avoiding misjudgments caused by single data deviations.

[0101] Specifically, while the infrared detection component moves along the surface of the indoor heat exchanger to collect condensate status information in each independent monitoring area, the image sensing component simultaneously collects surface images of the corresponding area. The collected image information is input into an image analysis algorithm. The algorithm, based on preset judgment rules (such as "areas with gray values ​​below a preset gray value threshold in the image are judged as condensate areas"), calculates the coverage area and distribution pattern of condensate in each independent monitoring area and outputs condensate distribution data at the image level. This data is then correlated with the distribution density and accumulation thickness data collected by the infrared detection component. If the condensate accumulation trends reflected by both are consistent (such as both showing a high degree of accumulation in a certain area), the data from the infrared detection component is used as the core to determine the degree of condensate accumulation in that area. If there is a significant difference between the two (such as infrared detection showing a high degree of accumulation, but image analysis showing no condensate characteristics), the infrared data and image information of that area are re-collected and analyzed again until the trends are consistent or the cause of the deviation is clarified (such as confirming that the infrared detection is interfered with by dust accumulation), and finally the accurate degree of condensate accumulation is determined.
