[0028] In order to make the objects, technical solutions and advantages of the application clearer, the technical solutions in the application will be described clearly and completely below with reference to the drawings in the application. Obviously, the described embodiments are some embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the application.

[0029] Air conditioners are indispensable devices in modern life, providing comfortable living and working environments for people. However, condensation problems often occur when using air conditioners. Most products on the market can handle basic humidity scenarios, but they perform poorly in high humidity conditions or large air volume outflow situations. The control method provided by the present invention focuses on controlling the coil temperature, adjusting the coil PID, and appropriately reducing the outdoor unit frequency. This method ensures low outflow temperature and meets the cooling effect while minimizing the production of condensation water.

[0030] The embodiments of the present invention are described below. Figures 1-3 The embodiments of the present invention are described below.

[0031] Figure 1 Figure 1 is a flowchart of the control method for high humidity dehumidification of an air conditioner according to the present invention, as shown in Figure 1 The method comprises the following steps.

[0032] S110, obtaining a preset humidity threshold for entering the high humidity dehumidification mode, and automatically switching to the high humidity dehumidification mode when detecting that the environmental humidity is greater than the humidity threshold.

[0033] In the control system of the air conditioner, a humidity threshold (RH1) is preset, which can be determined based on experimental data, user feedback or market demand, representing a critical point. When the environmental humidity exceeds this point, it is considered to be "high humidity". The air conditioner is equipped with a humidity sensor to monitor the indoor environmental humidity in real time. The humidity sensor continuously transmits the detected environmental humidity to the control system. After receiving the real-time humidity data from the humidity sensor, the control system compares it with the preset humidity threshold (RH1). If the detected environmental humidity is greater than the preset humidity threshold (RH1), the control system will determine that the current environment is a high humidity environment. Once it is determined that the current environment is a high humidity environment, the control system will automatically switch the working mode of the air conditioner to the high humidity dehumidification mode.

[0034] By automatically detecting the environmental humidity and triggering mode switching, the complexity of user manual operation is reduced, and the user experience is improved. When the environmental humidity suddenly rises and exceeds the safety threshold, the air conditioner can quickly switch to a working mode more suitable for the current environment, effectively preventing problems such as condensation. Timely mode switching can prevent damage to internal components of the air conditioner due to high humidity, prolonging the service life of the equipment. By automatically dehumidifying, the dryness of the indoor environment can be maintained, thereby improving the comfort of the occupants.

[0035] S120, obtaining a preset target coil temperature in the high humidity dehumidification mode, and determining a target frequency according to the target coil temperature.

[0036] According to the provided air conditioner high humidity dehumidification control method, the target frequency is determined according to the target coil temperature, specifically including: performing proportional-integral-derivative calculation according to the target coil temperature to obtain the target frequency.

[0037] According to the provided air conditioner high humidity dehumidification control method, proportional-integral-derivative calculation is performed according to the target coil temperature to obtain the target frequency, specifically including: determining proportional-integral-derivative control parameters; real-time detecting the current coil temperature, calculating the deviation of the target coil temperature and the current coil temperature; performing proportional-integral-derivative calculation according to the proportional-integral-derivative control parameters and the deviation to obtain proportional term, integral term and differential term; adding the proportional term, integral term and differential term to obtain the total control signal; adjusting the operating frequency of the air conditioner according to the total control signal, and determining the adjusted operating frequency as the target frequency.

[0038] Specifically, in the high humidity dehumidification mode, first set a target coil temperature (T1), which is the coil temperature that the air conditioner expects to reach, usually set to a suitable temperature that can ensure cooling effect and reduce condensation, such as 18℃. Set proportional (P), integral (I) and differential (D) three control parameters in the control system. These parameters can generally be determined by experiment and experience to ensure the stability and response speed of the control system. Real-time detect the current temperature of the air conditioner coil through the temperature sensor. The control system calculates the deviation between the target coil temperature (T1) and the currently detected coil temperature. According to the temperature deviation, use the proportional-integral-derivative PID control algorithm to calculate. The proportional term (P) is directly adjusted according to the size of the deviation; the integral term (I) is used to eliminate long-term deviation; the differential term (D) predicts the trend of future deviation and adjusts in advance. Add the proportional term, integral term and differential term to obtain the total control signal. According to the total control signal, the control system adjusts the operating frequency of the compressor of the air conditioner, so that the coil temperature tends to the target coil temperature (T1). The adjusted operating frequency is determined as the target frequency F n1 .

[0039] Through the PID control algorithm, the coil temperature can be more accurately controlled to stabilize around the preset target temperature, thereby improving the control accuracy of the air conditioning system. The PID control algorithm has the characteristics of fast response, and when the coil temperature deviates from the target temperature, the control system can quickly adjust to reduce temperature fluctuations. By accurately controlling the coil temperature, the generation of condensation at the air outlet of the air conditioner in a high humidity environment can be effectively reduced, and the user's experience can be improved. Reasonable frequency adjustment not only meets the cooling demand, but also reduces energy consumption to a certain extent, achieving energy saving and environmental protection. The integral term in the PID control algorithm helps to eliminate long-term deviation, and the differential term can predict and adjust in advance, thereby enhancing the stability of the entire air conditioning system.

[0040] S130. After the minimum operating time at the target frequency, detect the ambient humidity at the current moment, and determine whether to adjust the operating frequency of the air conditioner based on the detection results.

[0041] According to the provided control method for high humidity dehumidification of air conditioners, the ambient humidity at the current moment is detected, and the operating frequency of the air conditioner is adjusted based on the detection results. Specifically, this includes: obtaining the ambient humidity at the current moment, comparing the ambient humidity at the current moment with a humidity threshold, and determining whether to adjust the operating frequency of the air conditioner based on the comparison results.

[0042] According to the provided high humidity dehumidification control method for air conditioners, the operating frequency of the air conditioner is adjusted based on the comparison results. Specifically, if the difference between the ambient humidity and the humidity threshold is greater than a first percentage, the target frequency is maintained. If the difference between the ambient humidity and the humidity threshold is less than the first percentage but greater than a second percentage, the air conditioner operates at a frequency recalculated based on the coil proportional-integral-derivative calculation. If the difference between the ambient humidity and the humidity threshold is less than the second percentage, the air conditioner operates by subtracting the preset frequency from the frequency calculated by the coil proportional-integral-derivative calculation. After each frequency reduction, if the minimum operating frequency set by the air conditioner is reached, that frequency is maintained.

[0043] According to the provided control method for high humidity dehumidification of air conditioners, if the difference between the ambient humidity and the humidity threshold is less than the second percentage, the air conditioner will operate according to the frequency calculated by coil ratio-integral-derivative and then subtract the preset frequency. After each frequency reduction, if the ambient humidity remains below the humidity threshold and the duration exceeds the preset time threshold, the air conditioner will automatically switch to low humidity dehumidification mode or stop high humidity dehumidification mode.

[0044] Specifically, the air conditioner operates at the target frequency determined in step S120 and begins timing to ensure that the air conditioner operates at that frequency for at least a minimum time period T. min During this time, the frequency remains constant to ensure system stability and the acquisition of valid environmental data. After the timing ends, the ambient humidity (RH2) at the current moment is detected using the built-in humidity sensor. The detected ambient humidity value is compared with the preset humidity threshold (RH1), and the difference between them is calculated.

[0045] If the difference between the ambient humidity and the humidity threshold is greater than the first percentage (e.g., 10%), i.e., RH2-RH1>10%, it indicates that the ambient humidity is still high, and the target frequency F should be maintained. n1 run.

[0046] If the difference is less than the first percentage and greater than the second percentage (e.g., 5%), i.e., 10% > RH2 - RH1 > 5%, it indicates that the humidity has decreased but attention is still needed. At this time, the air conditioner will readjust its operating frequency based on the PID calculation results of the coil temperature.

[0047] If the difference is less than the second percentage, i.e. RH2-RH1<5%, it means that the ambient humidity has approached or fallen below the threshold value, at which point the air conditioner will reduce the operating frequency, specifically by subtracting a preset frequency (such as 5 Hz) from the frequency calculated by the PID.

[0048] After each frequency reduction operation, it will be checked whether the adjusted frequency reaches the minimum operating frequency set by the air conditioner. If so, it will be maintained at that frequency and no further reduction will be continued.

[0049] If the ambient humidity continues to be lower than the humidity threshold and the duration exceeds the preset time threshold (such as 30 minutes), the control system will determine that the current environment is no longer a high humidity environment, at which point it will automatically switch to a low humidity dehumidification mode or stop the high humidity dehumidification mode to adapt to the current environmental conditions.

[0050] By detecting the ambient humidity in real time and dynamically adjusting the operating frequency according to the humidity changes, the air conditioner can more flexibly adapt to different humidity environments. When the humidity decreases to a certain extent, the operating frequency is reduced to reduce energy consumption while maintaining dehumidification effect, achieving a balance between energy saving and efficiency. Avoiding running at high frequency when the humidity is too low, thereby reducing equipment wear and tear and prolonging the service life. By precisely controlling the humidity, a more comfortable living environment is provided for users. It can automatically switch the working mode according to the change of ambient humidity, reducing the user's manual operation, improving the convenience and intelligent level of use.

[0051] S140, after running for a preset time, continue to detect the ambient humidity at the current time and adjust the operating frequency of the air conditioner according to the detection results to realize cyclic detection and control.

[0052] Specifically, a preset time period is set in the control system, which can be a few minutes to a few hours, depending on the needs of the system and the characteristics of the environment. The air conditioner continues to run at the operating frequency adjusted in S130 until the preset time is reached. After the preset time is up, the ambient humidity at the current time is detected again by the built-in humidity sensor or external humidity detection device. After the control system obtains the humidity data transmitted by the humidity sensor, it will immediately analyze these data to determine the current ambient humidity. According to the current detected ambient humidity value, the control system will adjust the operating frequency of the air conditioner again according to the logic in S130. If the humidity is still high, the operating frequency may be maintained or increased; if the humidity is moderate or low, the operating frequency may be reduced. After completing the above steps, the control system will set a new preset time period again and repeat the detection of ambient humidity and adjustment of air conditioner operating frequency, forming a cyclic detection and control process.

[0053] By continuously detecting the environmental humidity and adjusting the operating frequency of the air conditioner, it can ensure that the air conditioning system always runs in the optimal state to cope with the changing environmental humidity. The cycle detection mechanism enables the air conditioning system to quickly respond to changes in environmental humidity, thereby achieving more accurate environmental humidity control. By adjusting the operating frequency in real time, it can avoid the air conditioner consuming too much energy when it does not need to run at high power, thereby improving the energy efficiency of the entire system. Reasonable adjustment of the operating frequency can reduce the wear and tear of the air conditioner, helping to extend the service life of the equipment. Through continuous monitoring and adjustment, it can ensure that the indoor environmental humidity is always maintained within a comfortable range, thereby improving the user's living or working experience.
