Description

Technical Field

[0001] This application relates to the field of air conditioning control technology, and in particular to a control method and electronic device for dual temperature and humidity control of an air conditioner. Background Technology

[0002] As a crucial device for regulating indoor air quality, air conditioners' core function is to provide users with a comfortable temperature and humidity environment. Currently, traditional air conditioners in cooling mode typically employ control logic with temperature as the sole control objective. However, human perception of thermal comfort depends not only on temperature but also on air humidity. In hot and humid environments such as rainy summers or the "return to spring" weather in southern China, the latent heat load indoors is significant. Traditional cooling control strategies often suffer from insufficient dehumidification while lowering the indoor temperature to the set value. This leads to a common phenomenon: although the indoor temperature has reached the user's set comfort value (e.g., 26℃), the relatively high humidity (e.g., exceeding 70%) makes it difficult for sweat to evaporate, resulting in a feeling of "stuffy heat" or "damp cold," leading to poor comfort.

[0003] To alleviate the discomfort caused by excessive humidity, users often resort to further lowering the set temperature (e.g., setting it to 23°C or lower), forcibly extending the high-frequency cooling time of the air conditioner to increase dehumidification. While this reduces indoor humidity, it also directly leads to indoor temperatures far below the human comfort range, resulting in an "overly cold" indoor environment. This not only significantly increases air conditioner energy consumption and wastes energy but also easily causes users to catch a cold, leading to "air conditioning sickness." Existing air conditioning control technology struggles to automatically balance cooling and dehumidification needs during the cooling process, failing to effectively control humidity within a comfortable range while maintaining a suitable temperature. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a control method and electronic device for dual temperature and humidity control of air conditioning, which can effectively solve the technical pain points of "cooling without dehumidifying" or "dehumidifying leading to overcooling" during traditional air conditioning cooling, and realize dual coupled control of temperature and humidity.

[0005] In a first aspect, embodiments of this application provide a control method for dual temperature and humidity control of an air conditioner.

[0006] The air conditioning temperature and humidity dual control method according to an embodiment of this application includes: responding to a cooling command and determining a target humidity and a target temperature according to the cooling command, and collecting indoor ambient humidity; determining and dynamically adjusting a first operating parameter and a second operating parameter according to the indoor ambient humidity and the target humidity, so that the indoor ambient humidity is less than or equal to the target humidity; wherein, the first operating parameter is used to characterize the maximum operating frequency of the compressor, and the second operating parameter is used to characterize the operating speed of the indoor fan; collecting indoor ambient temperature; and re-determining and dynamically adjusting the first operating parameter and the second operating parameter according to the indoor ambient temperature and the target temperature.

[0007] The air conditioning temperature and humidity dual control method according to the embodiments of this application has at least the following beneficial effects: The air conditioning temperature and humidity dual control method of the embodiments does not simply execute conventional cooling logic. Instead, it first determines and dynamically adjusts the maximum operating frequency of the compressor and the operating speed of the indoor fan based on the comparison between the indoor ambient humidity and the target humidity, thereby prioritizing intervention on indoor humidity to ensure that the indoor humidity can quickly drop to a comfortable target humidity range. After the humidity reaches the target, the method further collects the indoor ambient temperature and readjusts the compressor frequency and fan speed according to the temperature difference, smoothly transitioning to the temperature control stage. Through this phased, multi-parameter coordinated adjustment control strategy, this application can effectively solve the technical pain points of "cooling without dehumidifying" or "dehumidifying leading to overcooling" during traditional air conditioning cooling, achieving dual coupling control of temperature and humidity. This ensures both the dehumidification efficiency in the initial stage of cooling and the stability of subsequent temperature control, thereby significantly improving the user's comfort in cooling mode.

Based on the new indoor ambient humidity and the compensated humidity, the indoor corrected humidity is re-determined. Based on the indoor corrected humidity and the humidity control comparison table, the first operating parameter and the second operating parameter are adjusted so that the indoor ambient humidity is less than or equal to the target humidity.

[0010] According to some embodiments of this application, the humidity control reference table is used to characterize the correspondence between several consecutive humidity threshold intervals and the first operating parameter and the second operating parameter; The step of determining the first operating parameter and the second operating parameter based on the indoor corrected humidity and the humidity control lookup table includes: Based on the indoor corrected humidity and the humidity control reference table, the target humidity range is determined from several consecutive humidity threshold ranges; Based on the target humidity range and the humidity control reference table, determine the first operating parameter and the second operating parameter.

[0011] According to some embodiments of this application, in the humidity control comparison table, the larger the amplitude of the humidity threshold range, the larger the corresponding first operating parameter, and the smaller the corresponding second operating parameter.

[0012] According to some embodiments of this application, after determining the indoor corrected humidity based on the indoor ambient humidity and the compensated humidity, the method further includes: When the indoor corrected humidity is less than or equal to the target humidity, the step of collecting the indoor ambient temperature is performed directly.

[0013] According to some embodiments of this application, the step of redetermining and dynamically adjusting the first operating parameter and the second operating parameter based on the indoor ambient temperature and the target temperature includes: Obtain the preset temperature control reference table; Based on the indoor ambient temperature and the temperature control reference table, the first operating parameter and the second operating parameter are re-determined. At preset intervals, the indoor ambient temperature is acquired again, and the first and second operating parameters are adjusted according to the indoor ambient temperature and the temperature control reference table so that the indoor ambient temperature is less than or equal to the target temperature.

[0014] According to some embodiments of this application, the temperature control reference table is used to characterize the correspondence between several consecutive temperature threshold intervals and the first operating parameter and the second operating parameter; The step of re-determining the first operating parameter and the second operating parameter based on the indoor ambient temperature and the temperature control reference table includes: Based on the indoor ambient temperature and the temperature control reference table, the target temperature range is determined from several consecutive temperature threshold ranges; Based on the target temperature range and the temperature control reference table, the first operating parameter and the second operating parameter are re-determined.

[0015] According to some embodiments of this application, when the target temperature range is the temperature threshold range with the smallest amplitude among all the temperature threshold ranges, the compressor is controlled to run for a preset time and then stop.

Only after obtaining the user's separate permission or consent is the necessary user-related data required for the proper functioning of these embodiments acquired.

[0024] In a first aspect, embodiments of this application provide a control method for dual temperature and humidity control of an air conditioner.

[0025] like Figure 1As shown, the air conditioning temperature and humidity dual control method in the embodiment includes, but is not limited to, steps S100 to S400: S100 responds to the cooling command and determines the target humidity and target temperature based on the cooling command, as well as collecting the indoor ambient humidity; S200. Based on the indoor ambient humidity and the target humidity, determine and dynamically adjust the first operating parameter and the second operating parameter to make the indoor ambient humidity less than or equal to the target humidity; wherein, the first operating parameter is used to characterize the maximum operating frequency of the compressor, and the second operating parameter is used to characterize the operating speed of the indoor fan; S300: Collect indoor ambient temperature; S400: Based on the indoor ambient temperature and the target temperature, redetermine and dynamically adjust the first and second operating parameters.

[0026] In step S100, when the user issues a cooling start command or mode switching command via remote control, mobile terminal, or control panel, the air conditioner's controller receives and responds to the cooling command. To achieve dual temperature and humidity control, the system first needs to establish a control baseline. The target temperature is typically a user-set value (e.g., 26°C); the target humidity can be manually set by the user (e.g., 50%), or it can be a pre-set standard humidity value within the system that conforms to human comfort conditions (e.g., a specific value within the 40%-60% range). Simultaneously, the air conditioner collects the current indoor humidity in real time using a built-in or external humidity sensor, serving as the initial basis for subsequent control strategy decisions.

[0027] In step S200, the "humidity priority control" stage is in progress. The controller compares the collected indoor ambient humidity with the target humidity. If the current humidity is higher than the target humidity, it indicates that the main problem indoors is excessive latent heat load (humidity), and the system enters strong dehumidification logic. Under this logic, the controller calculates or matches the first and second operating parameters required for the current operating conditions.

[0028] The first operating parameter (maximum operating frequency of the compressor): This parameter limits the maximum output capacity that the compressor can achieve at the current stage. During the humidity control stage, by reasonably setting this upper limit of frequency, it is possible to prevent the compressor from running excessively, which could lead to evaporator frosting or excessively rapid temperature drop, while ensuring sufficient cooling capacity for dehumidification.

[0029] The second operating parameter (indoor fan speed): The fan speed directly affects the airflow velocity and heat exchange efficiency through the evaporator. During the humidity control phase, the surface temperature of the evaporator can be changed by dynamically adjusting the fan speed, thereby controlling the dehumidification rate.

[0030] The controller sends these two parameter commands to the actuator, driving the compressor to operate within a defined frequency range and driving the fan to deliver air at a defined speed. As the air conditioner operates, the system continuously or periodically monitors humidity changes and dynamically updates these two parameters until the indoor humidity drops to meet the conditions (i.e., less than or equal to the target humidity).

[0031] In step S300, the system continuously collects indoor ambient temperature data using a temperature sensor. Although the system may be continuously monitoring the temperature after S100, in this control logic, step S300 emphasizes temperature monitoring after humidity control intervention or in parallel with humidity control, in order to prepare data for subsequent control handover.

[0032] In step S400, when the system determines that the humidity has reached the target (i.e., the indoor ambient humidity is less than or equal to the target humidity) or when specific switching conditions are met, the control logic shifts its focus to the control of the sensible heat load (temperature), i.e., it enters the "temperature control stage". At this time, the controller recalculates and adjusts the first and second operating parameters based on the difference between the current indoor ambient temperature and the user-set target temperature. In this stage, the adjustment of the first operating parameter (maximum operating frequency of the compressor) is no longer primarily for dehumidification, but rather to provide the cooling capacity required for rapid cooling or maintaining the temperature; the adjustment of the second operating parameter (indoor fan operating speed) is to accelerate indoor air circulation so that the room temperature quickly and evenly reaches the set value.

[0033] The embodiment of the air conditioner temperature and humidity dual control method, through this phased dynamic adjustment, can first quickly remove excess moisture by using a specific frequency and fan speed combination. After the humidity is comfortable, it automatically switches to a temperature-oriented frequency and fan speed combination, thereby avoiding the problems of "temperature meets the standard but humidity is still very high" or "temperature is too low in order to dehumidify" in the traditional cooling mode.

[0034] In practical applications, the humidity sensor of an air conditioner is typically installed inside the indoor unit (e.g., at the return air vent). Because there is a physical distance between the internal environment of the air conditioner and the central area of ​​the room where the user actually spends time, and because the humidity is affected by the radiant temperature or airflow of the air conditioner's components (such as the heat exchanger), the "indoor humidity" directly collected by the sensor often cannot accurately reflect the true humidity at the user's perceived location. To eliminate this detection bias, a humidity compensation mechanism is introduced in some embodiments. In some embodiments, such as... Figure 2 As shown, step S200 further includes, but is not limited to, steps S210 to S230: S210, Obtain compensated humidity; S220. Determine the corrected indoor humidity based on the indoor ambient humidity and the compensated humidity; S230. Based on the indoor corrected humidity and the target humidity, determine and dynamically adjust the first operating parameter and the second operating parameter to make the indoor ambient humidity less than or equal to the target humidity.

[0035] In step S210, the compensating humidity is a preset correction value used to calibrate the deviation between the sensor reading and the actual ambient humidity. This compensating humidity can be a fixed value calibrated at the factory based on a large amount of experimental data (e.g., +3% or -2%); or it can be a dynamic value adaptively generated by the air conditioner main control board based on the current installation environment, model structure, or historical operating data.

[0036] In step S220, the control system performs a calculation (usually a weighted sum) on the original "indoor ambient humidity" collected in step S100 and the "compensated humidity" obtained in step S110 to obtain the "corrected indoor humidity". For example, if the humidity collected by the sensor is 60%, considering that the sensor is located inside the machine and the environment is relatively humid, the preset compensation humidity is -5%, and the final determined corrected indoor humidity is 55%. Through this step, the subsequent control logic of the system will be based on the "corrected indoor humidity" that is closer to the real environment, thereby avoiding over-dehumidification due to falsely high detection or insufficient dehumidification due to falsely low detection.

[0037] In step S230, after obtaining accurate indoor corrected humidity, in order to achieve precise and stable control, the air conditioning temperature and humidity dual control method of this embodiment abandons the traditional simple on / off control (i.e., turning on when humidity is high and turning off when humidity is low), and instead adopts a hierarchical control strategy based on a "humidity control reference table". In some embodiments, such as Figure 3 As shown, step S230 further includes steps S231 to S233: S231. Obtain the preset humidity control reference table; S232. Determine the first operating parameter and the second operating parameter based on the indoor corrected humidity and humidity control comparison table; S233. After a preset interval, obtain the indoor ambient humidity again, redetermine the indoor corrected humidity based on the new indoor ambient humidity and the compensated humidity, and adjust the first and second operating parameters according to the indoor corrected humidity and humidity control comparison table so that the indoor ambient humidity is less than or equal to the target humidity.

[0038] In step S231, the humidity control lookup table can be pre-stored in the memory of the air conditioner controller. It establishes a standardized mapping relationship from "humidity status" to "equipment operating parameters".

[0039] In step S232, the system uses the currently calculated "indoor corrected humidity" as an index value to search and match in the "humidity control lookup table," directly retrieving the corresponding first operating parameter (compressor's maximum operating frequency) and second operating parameter (fan speed). For example, when the indoor corrected humidity is extremely high, the table is consulted to match the parameters for the powerful dehumidification mode; when the indoor corrected humidity is only slightly higher than the target humidity, the table is consulted to match the parameters for the weak dehumidification mode.

[0040] In step S233, the control of the air conditioning system is a dynamic closed-loop process. Ambient humidity does not change abruptly, and to protect the compressor and prevent frequent system oscillations, control parameters should not change constantly. Therefore, this step sets a "preset time" (e.g., 3 minutes or 5 minutes) as the control cycle. Every preset time, the system re-executes the "acquisition-compensation-table lookup-execution" closed-loop process: 1) Acquire the latest sensor data and perform compensation to obtain the latest corrected indoor humidity. 2) Determine the current dehumidification effect. If the humidity has decreased significantly after the previous cycle, the system may look up a lower operating parameter to reduce energy consumption and noise; if the humidity decreases slowly or even rebounds, the system may maintain the current parameters or switch to a higher parameter level. 3) This periodic adjustment mechanism ensures that the air conditioner always operates in a state best matched to the current load until the corrected indoor humidity finally stabilizes below the target humidity.

[0041] Furthermore, in some embodiments, to avoid the system frequently changing its operating state due to minor fluctuations in humidity, the concept of "range control" is adopted. That is, the continuously changing humidity difference is discretized into several stable control ranges.

[0042] For example, the humidity control lookup table establishes a one-to-one mapping between "humidity threshold ranges" and "operating parameter combinations." First, the system needs to calculate the difference index. Typically, this difference... H is the difference between the corrected indoor humidity and the target humidity. H = Indoor Corrected Humidity - Target Humidity). "Several consecutive humidity threshold intervals" can be based on... The hierarchy is determined by the size of H.

[0043] Correspondingly, such as Figure 4 As shown, in some embodiments, step S232 further includes, but is not limited to, steps S232a to S232b: S232a. Determine the target humidity range from several consecutive humidity threshold ranges based on the indoor corrected humidity and humidity control comparison table. S232b. Determine the first and second operating parameters based on the target humidity range and humidity control reference table.

[0044] In step S232a, it is assumed that the system presets three humidity threshold ranges (this is just an example; in actual applications, it can be adaptively adjusted according to the range and precision of humidity regulation): Range A (light dehumidification, 0 < H≤5%); Zone B (general dehumidification, 5% < H≤15%); Range C (powerful dehumidification, 15% < H). The system determines the current... Whichever interval H falls into, that interval will be locked as the "target humidity interval".

[0045] In step S232b, once the target humidity range is determined, the system directly reads the first operating parameter (target compressor frequency) and the second operating parameter (target indoor fan speed) corresponding to the target humidity range.

[0046] Understandably, in some embodiments, in order to achieve the best temperature and humidity control effect, the parameters in the humidity control reference table are set according to a specific thermodynamic logic, that is: in the humidity control reference table, the larger the amplitude of the humidity threshold range, the larger the corresponding first operating parameter, and the smaller the corresponding second operating parameter.

[0047] Here, "the larger the amplitude" refers to the greater the degree to which the indoor humidity represented by that range exceeds the target humidity (i.e., the greater the moisture load). For example, the specific correspondence and principle are as follows: High humidity condition (corresponding to range C, maximum amplitude). Set the highest first operating parameter (e.g., compressor running at high frequency, such as 70Hz-90Hz), and simultaneously set the lowest second operating parameter (e.g., fan running at low or ultra-low speed). In this condition, indoor humidity is severely excessive, requiring rapid dehumidification. The compressor's high frequency rapidly lowers the evaporator coil temperature to well below the dew point, greatly enhancing condensation and water removal capabilities. The fan operates at low speed, reducing the airflow velocity through the evaporator. The slower the flow rate, the longer the residence time (heat exchange time) of the humid air on the surface of the cooling coil, resulting in more thorough condensation of moisture (maximizing latent heat exchange). This combination is the "deep cooling dehumidification" mode, which reduces absolute humidity as quickly as possible.

[0048] Medium humidity condition (corresponding to range B, amplitude in the middle). Set the first operating parameter to medium (e.g., compressor medium frequency, such as 40Hz-60Hz), and simultaneously set the second operating parameter to medium (e.g., fan medium speed). At this time, the humidity has decreased. To prevent the evaporator from freezing or the outlet air temperature from being too low, appropriately reduce the compressor frequency; at the same time, appropriately increase the fan speed to increase the circulating air volume, and begin to balance dehumidification and cooling.

[0049] Low humidity condition (corresponding to range A, minimum amplitude). Set a smaller first operating parameter (e.g., compressor low frequency, such as 20Hz-30Hz), while setting a larger second operating parameter (e.g., fan high speed). At this point, the indoor humidity is close to the target value (in the fine-tuning stage). Maintain basic cooling capacity to avoid energy waste and excessive dehumidification. At this point, the dehumidification demand decreases, and the control focus gradually shifts to "maintaining temperature uniformity." A higher fan speed helps improve the sensible heat exchange ratio, prevents indoor temperature stratification, and prepares the airflow for the upcoming S300 and S400 (temperature control stages).

[0050] Through the above-mentioned "reverse coupling" control strategy (i.e., the greater the humidity deviation, the faster the compressor runs but the slower the airflow), the control method of dual temperature and humidity control of the air conditioner in the embodiment can intelligently and seamlessly switch between "deep dehumidification" and "comfort maintenance" according to the current urgency of dehumidification, thereby solving the problem that traditional air conditioners have low dehumidification efficiency due to excessive airflow or slow dehumidification due to fixed frequency.

[0051] Understandably, during the dehumidification phase, in pursuit of maximum dehumidification efficiency, the system often sacrifices some cooling speed (because low fan speed limits the airflow). Once it enters the temperature control phase, the control objective changes, and the system logic also changes accordingly. For example... Figure 5 As shown, in some embodiments, step S400 further includes steps S410 to S430: S410, Obtain the preset temperature control reference table; S420. Based on the indoor ambient temperature and temperature control reference table, re-determine the first and second operating parameters; S430: After a preset interval, acquire the indoor ambient temperature again, and adjust the first and second operating parameters according to the indoor ambient temperature and temperature control reference table to make the indoor ambient temperature less than or equal to the target temperature.

[0052] In step S410, similar to the humidity control lookup table, the temperature control lookup table is also pre-stored in the system. However, unlike the humidity control lookup table, the parameter mapping relationships in this table are specifically designed for "rapid cooling" and "constant temperature maintenance" scenarios.

[0053] In step S420, the system first calculates the temperature difference. T( T = Indoor ambient temperature - Target temperature). Since the humidity has reached the target level (the air is relatively dry), the user's sensitivity to temperature increases. The system uses a lookup table to determine how the compressor and fan should work together. For example,... Figure 6 As shown, step S420 further includes, but is not limited to, steps S421 to S422: S421. Based on the indoor ambient temperature and temperature control reference table, determine the target temperature range from several consecutive temperature threshold ranges. S422. Based on the target temperature range and temperature control reference table, redetermine the first and second operating parameters.

[0054] In step S421, for example, the temperature control lookup table will... T is divided into several continuous intervals, for example: Rapid cooling zone (large temperature difference): T≥3℃; Normal range (temperature difference): 1℃≤ T≤3℃; Constant temperature range (small temperature difference): T≤1℃.

[0055] Select the current temperature difference from the temperature threshold intervals within these intervals. The range that T meets is taken as the target temperature range.

[0056] In step S422, the correspondence of parameters generally follows the principle of forward coupling (in contrast to the "reverse coupling" in the dehumidification stage).

[0057] For example, when in the "rapid cooling zone" (large temperature difference): set a higher first operating parameter (high-frequency compressor) and a higher second operating parameter (high fan speed). High frequency provides maximum cooling capacity, while high fan speed maximizes the number of indoor air circulations, allowing the cooling capacity to quickly spread to every corner of the room for rapid cooling. Although the high fan speed may slightly reduce dehumidification efficiency at this time, since the humidity has already been reduced to a low level in the previous stage (S200 stage), and the high sensible heat ratio cooling at high fan speed can also maintain a certain dehumidification capacity, it will not cause a significant rebound in humidity.

[0058] When in the "normal range" (within the temperature difference): the compressor is reduced to medium frequency and the fan is switched to medium speed; smooth transition to avoid overcooling.

[0059] When in the "constant temperature range" (small temperature difference): the compressor runs at low frequency and the fan runs quietly at low speed; the main purpose at this time is to counteract external heat penetration, maintain a constant room temperature, and at the same time reduce noise and energy consumption, providing the most comfortable physical environment.

[0060] Understandably, after the system has been running for a period of time in step S400 (temperature control phase), the indoor temperature will gradually decrease. To prevent energy waste and user discomfort due to excessively low room temperature, some embodiments include corresponding shutdown or standby mechanisms. For example, the temperature control lookup table contains several temperature threshold ranges. The "temperature threshold range with the smallest amplitude" typically refers to the temperature difference... T is very small, even negative (i.e., the room temperature is below the set temperature). When the table lookup result shows the current... When temperature (T) falls within the minimum range, it indicates that the required cooling has been achieved or there has been slight overcooling. At this point, the system will not immediately cut off the compressor power. The system will start a timer to maintain the current operating state or enter the lowest frequency operating state. Within this "preset duration" (e.g., 3 minutes), the system continuously monitors the temperature. If the temperature rises, the timer stops; if the temperature remains within the minimum range, it indicates that the room temperature has indeed reached and stabilized below the set value. After the timer ends, the system controls the compressor to stop running (shutdown). At this time, the indoor fan usually does not completely stop but switches to a low / very low fan speed to maintain micro-circulation of indoor air, facilitating accurate detection of temperature rises. The compressor will be restarted once the temperature rises again.

[0061] In step S430, similar to the dehumidification stage, the temperature control stage also employs a periodic (e.g., every 30 seconds or 1 minute) closed-loop detection mechanism. The system continuously monitors... The change in temperature (T) occurs as refrigeration progresses. When temperature T drops from the "rapid cooling zone" to the "normal zone," the system will automatically reduce the compressor frequency and fan speed. If... If T increases again, the system will increase the frequency and wind speed again; if As temperature (T) gradually decreases, the system reduces its frequency and fan speed. This dynamic adjustment ensures that the indoor temperature consistently approaches and eventually stabilizes near the target temperature.

[0062] Understandably, in actual use, the indoor environment is not always humid when the cooling is turned on. For example, in dry northern regions, or when adjusting the settings after the air conditioner has been running for a while, the indoor environment may already be in a "dry and hot" state. In this case, mechanically executing the dehumidification program would not only waste time but also lead to excessive dryness in the room, causing discomfort such as dry mouth and throat for the user. Therefore, in some embodiments, step S500 is included after step S220: S500: When the indoor corrected humidity is less than or equal to the target humidity, directly execute the step of collecting the indoor ambient temperature.

[0063] In step S500, the current indoor corrected humidity is compared with the target humidity. If the indoor corrected humidity > the target humidity, the system proceeds to step S200 and activates the "dehumidification priority" mode (high frequency, low fan speed). If the indoor corrected humidity ≤ the target humidity, the system determines that dehumidification is not currently required. At this time, the controller will skip the setting and adjustment of dehumidification parameters in step S200 and directly jump to steps S300 (collecting indoor ambient temperature) and S400 (temperature control stage).
