[0070] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings.

The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present invention.

[0072] It should be understood that although the terms first, second, third, etc. may be used to describe various information in embodiments of the present invention, such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, without departing from the scope of embodiments of the present invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0073] Currently, air conditioners can automatically adjust room temperature and humidity based on user needs. A common humidity control method involves setting thresholds for when the humidity function is turned on and off. When the humidity reaches these thresholds, the dehumidification function is turned on or off. The humidity level in the target space is typically detected by a humidity sensor installed at the air conditioner's return air vent.

[0074] Research has found that when an air conditioner is cooling or dehumidifying, moisture in the humid air condenses into small droplets when it comes into contact with the cooler indoor heat exchanger. These droplets then drip into the water channel at the base of the indoor unit and flow outdoors through the drainpipe. Other droplets cling to the evaporator fins. When cooling / dehumidification is stopped, the indoor circulation fan does not stop immediately because the air duct needs to remain dry. These droplets remaining on the evaporator participate in the air circulation and return to the room.

[0075] When the air conditioner reaches the shutdown threshold, it stops dehumidifying and the water droplets / humid air in the air duct are blown into the room, causing the indoor humidity to rise, which can lead to the following problems:

[0076] 1) When the dehumidification function threshold is reached, if the ambient humidity rises above the dehumidification threshold, the air conditioner will frequently start and stop the dehumidification function, and the dehumidification effect will not be achieved;

[0077] 2) For apps or air conditioner displays that have a real-time humidity display function, the humidity may rise after the air conditioner is turned off or fluctuate repeatedly when the function is turned on, which may cause confusion to users;

[0078] 3) Since the moisture in the air duct will be blown back into the room, the dehumidification function of the air conditioner will not achieve the expected effect.

[0079] Figure 1 FIG. 1 is a flow chart showing a method for controlling a target device according to an exemplary embodiment. Figure 1 , the method may include the following steps:

[0080] S100, detecting the current ambient temperature, the first ambient humidity, and the current coil temperature of the heat exchanger in the target space;

[0081] S200, determining a target humidity correction value according to the current ambient temperature, the first ambient humidity, and the current coil temperature of the heat exchanger;

[0082] S300, correcting the first ambient humidity according to the target humidity correction value to obtain a second ambient humidity;

[0083] S400 : Controlling the operation of the target device according to the second ambient humidity and a target ambient value of the target device, wherein the target ambient value includes: target humidity and / or target temperature.

[0084] In the embodiments of the present disclosure, the target device control method can be applied to an electronic device, which can be a device that is communicatively connected to the target device, including but not limited to user terminals such as smartphones, tablet computers, wearable devices, and smart speakers. Here, the user terminal can be a device associated with the target device, for example, a terminal device having a built-in application for controlling the operation of the target device. Of course, the electronic device can also be the target device.

[0085] For example, the target device may include but is not limited to an air conditioner, a dehumidification and cooling device, etc. The air conditioner may be a cabinet air conditioner or a wall-mounted air conditioner.

[0086] The target device is capable of regulating the environment of the target space. For example, the target device is capable of reducing the humidity and / or regulating the temperature within the target space, such as by cooling or heating the target space. The target space may be a relatively enclosed area, such as a living room or bedroom.

[0087] In the above step S100 , when the target device meets the starting condition for the environmental humidity correction, the current environmental temperature, the first environmental humidity, and the current coil temperature of the heat exchanger in the target space may be detected by the environmental sensor.

[0088] In some examples, the starting conditions for the ambient humidity correction include:

[0089] Condition 1: The target device enters a preset operating mode; here, the preset operating mode is an operating mode capable of reducing the ambient humidity in the target space, wherein the preset operating mode can be a cooling mode or a dehumidification mode.

[0090] Condition 2: The operating frequency of the compressor of the target device is not equal to 0.

[0091] In some examples, the triggering condition for the target device to enter the preset working mode may be:

[0092] The first ambient humidity in the target space reaches a humidity threshold for starting a dehumidification function of the target device, or a start instruction for a preset working mode of the target device is received.

[0093] In this embodiment, if it is determined that all of the starting conditions for the ambient humidity correction are met, then steps S100 to S400 may be triggered. If it is determined that all of the starting conditions for the steady-state determination are not met, then steps S100 to S400 or steps S200 to S400 are not executed.

[0094] When the target device is in cooling or dehumidification mode, the heat exchanger in the target space acts as an evaporator, absorbing heat. As air in the target space is drawn in by the indoor unit's fan and passes through the evaporator, moisture condenses into small droplets. Some of these droplets are discharged outside the target space through the drain pipe, while others adhere to the evaporator's fins.

[0095] The current ambient temperature in the target space, ie, the current indoor ambient temperature, can be detected by a temperature sensor provided at the return air outlet of the indoor unit of the target device.

[0096] The first ambient humidity within the target space is the relative humidity (RH) of the current indoor environment. Relative humidity refers to the percentage of the actual water vapor density per unit volume of air to the saturated water vapor density at the same temperature. This first ambient humidity can be detected by a humidity sensor located at the return air vent of the indoor unit of the target device. The humidity sensor can be a resistive-capacitive humidity sensor.

[0097] The current coil temperature of the heat exchanger in the target space, that is, the current coil temperature of the indoor heat exchanger, can be detected by a temperature sensor provided on the heat exchanger coil.

[0098] In the above step S200, a dew point temperature value may be determined according to the current ambient temperature and the first ambient humidity, and a target humidity correction value may be determined according to the difference between the dew point temperature value and the current coil temperature of the heat exchanger.

[0099] In the above step S300 , the sum of the target humidity correction value and the first ambient humidity may be determined as the second ambient humidity.

[0100] In the above step S400, the operating frequency of the compressor and / or the speed of the fan of the target device may be controlled according to the second ambient humidity and the target ambient value of the target device.

[0101] Wherein, the target environmental value includes: target humidity and / or target temperature.

[0102] Here, when the target device is in dehumidification mode, the target temperature of the target device can be: the ambient temperature in the target space when the dehumidification mode starts minus the temperature value of the preset value, which can be 2℃±1℃; the target humidity of the target device can be a humidity value set in advance according to user needs, or it can be the optimal humidity value pre-stored in the target device.

[0103] When the target device is in cooling mode, the target temperature of the target device can be a temperature value pre-set according to user requirements or a pre-stored optimal temperature value for the target device. The target humidity of the target device can be a humidity value determined based on a pre-stored correspondence between target temperature and target humidity. For example, when the target temperature is set to 25°C, the target humidity corresponding to the target temperature is 50%.

[0104] Specifically, in the process of implementing the above-mentioned step S400, when the second ambient humidity is greater than the target humidity in the target ambient value, or the second ambient humidity is greater than the ambient humidity value corresponding to the target temperature in the target ambient value, the target device is controlled to keep working in the current working mode; or, when the second ambient humidity is equal to the target humidity in the target ambient value, or the second ambient humidity is equal to the ambient humidity value corresponding to the target temperature in the target ambient value, the target device is controlled to exit the current working mode.

[0105] When the target device is cooling / dehumidifying, some water droplets will adhere to the evaporator of the target device in the target space, causing the humidity value detected by the humidity sensor to deviate from the actual ambient humidity value. After the target device reaches the threshold for shutting down the dehumidification function, the water droplets / humid air in the air duct will be blown into the room, causing the first ambient humidity in the room to rise, which will cause the target device to start and stop frequently.

[0106] In the control method for the target device provided in the embodiment of the present disclosure, a target humidity correction value is determined by utilizing the current ambient temperature in the target space, the first ambient humidity, and the current coil temperature of the heat exchanger. The first ambient humidity is corrected according to the target humidity correction value to obtain a second ambient humidity. In this way, by correcting the first ambient humidity in the target space to obtain the second ambient humidity, the corrected ambient humidity can be made closer to the true value of the humidity. In this way, by controlling the operation of the target device based on the second ambient humidity and the target ambient value of the target device, not only can the frequent start-up and shutdown of the target device caused by repeated opening and closing of the dehumidification function of the target device be effectively reduced, thereby reducing the energy consumption of the device, but also the accuracy of the dehumidification control of the target device and the dehumidification effect can be improved.

[0107] For example, assuming that the target humidity of the dehumidification mode of the target device is 50%, and the first ambient humidity in the target space is 50%, if the target humidity correction value determined based on the current ambient temperature in the target space, the first ambient humidity, and the current coil temperature of the heat exchanger is 5%, then the sum of the target humidity correction value and the first ambient humidity can be used as the second ambient humidity, that is, the second ambient humidity is 55%, and the target device is controlled to continue working in the dehumidification mode until the second ambient humidity is the same as the target humidity, then exit the dehumidification mode. At this time, the first ambient humidity detected in the target space will be lower than the target humidity (50%). In this way, after the target device reaches the threshold for shutting down the dehumidification function, the probability of the target device being frequently started and stopped due to the water droplets / humid air in the air duct being blown out into the room, causing the first ambient humidity in the room to rise, can be reduced.

[0108] In some embodiments, the method may further include:

[0109] When the target device is in a preset working mode, displaying the second ambient humidity on a preset display interface;

[0110] After the target device exits the preset working mode, the first ambient humidity is displayed on the preset display interface, wherein the preset display interface is: the display interface of the target device or the display interface of a user terminal associated with the target device.

[0111] In this embodiment, when the target device is in a preset working mode, the second ambient humidity obtained by correcting the first ambient humidity with the target humidity correction value is displayed on the preset display interface, and after the target device exits the preset working mode, the first ambient humidity is displayed on the preset display interface, which can effectively reduce the occurrence of repeated fluctuations in humidity on the display interface when the air conditioner rises after it is turned off or when the function is turned on.

[0112] In some embodiments, as Figure 2 As shown, the determination of the target humidity correction value according to the current ambient temperature, the first ambient humidity, and the current coil temperature of the heat exchanger in step S200 may include:

[0113] S210: Determine a dew point temperature value according to the current ambient temperature and the first ambient humidity.

[0114] Specifically, the dew point temperature value may be calculated according to a preset formula based on the current ambient temperature and the first ambient humidity.

[0115] In addition, according to the current ambient temperature and the first ambient humidity, a dew point temperature value having a mapping relationship with the first ambient humidity at the current ambient temperature may be found from a preset mapping relationship table.

[0116] The preset mapping relationship table includes a mapping relationship between ambient humidity and dew point temperature values at different ambient temperatures. The mapping relationship can be set in advance based on experimental data or expert experience and is not specifically limited here.

[0117] S220: Determine the target humidity correction value according to the dew point temperature value and the current coil temperature of the heat exchanger.

[0118] In some examples, the target humidity correction value may be determined based on a product of a difference between a dew point temperature value and a current coil temperature of the heat exchanger and a correction factor.

[0119] Here, the correction coefficient may be a value that is negatively correlated with the operating time of the target device in the current operating mode (e.g., cooling mode or dehumidification mode). Alternatively, the correction coefficient may be a preset value determined through extensive experimental data training or expert experience, and is not specifically limited here.

[0120] The correction coefficient may be in the range of greater than or equal to 0 and less than or equal to 0.75.

[0121] In other examples, a corresponding target humidity correction value can be found from a preset correspondence table based on the difference between the dew point temperature and the current coil temperature of the heat exchanger. The preset correspondence table includes a correspondence between the difference between the dew point temperature and the heat exchanger coil temperature and the humidity correction value. This correspondence can be pre-set based on experimental data or expert experience and is not specifically limited here.

[0122] In this embodiment, the dew point temperature value is determined based on the current ambient temperature and the first ambient humidity, and the target humidity correction value is determined based on the dew point temperature value and the current coil temperature of the heat exchanger. Compared with directly using a fixed humidity correction value for humidity correction, this can make the deviation between the corrected ambient humidity and the actual humidity value smaller, thereby improving the accuracy of the ambient humidity value.

[0123] In some embodiments, in step S210, determining the dew point temperature value according to the current ambient temperature and the first ambient humidity may include:

[0124] The current ambient temperature and the first ambient humidity are used as input parameters of a preset fitting formula, and the dew point temperature value is calculated according to the preset fitting formula.

[0125] Wherein, the preset fitting formula is:

[0126] T dew =A+B*Tin +C*U+D*T in 2 -E*U 2 +F*T in *U in ;

[0127] Among them, T dew is the dew point temperature value, T in is the current ambient temperature in the target space, U is the first ambient humidity in the target space (ie, the relative humidity detection value in the current target space), and the values of A to F are all preset constants.

[0128] In specific applications, the dew point temperature value can be calculated according to the following preset fitting formula:

[0129] T dew =-30.3843+0.7012*T in +61.2194*U+0.0005*T in 2 -32.8593*U 2 +0.3250*T in *U.

[0130] In this embodiment, the dew point temperature value is calculated by fitting the current ambient temperature and the first ambient humidity according to the preset fitting formula, thereby ensuring the reliability of the dew point temperature value.

[0131] In some embodiments, as Figure 3 As shown, based on Figure 2 The step S220 of determining the target humidity correction value according to the dew point temperature and the current coil temperature of the heat exchanger may include:

[0132] S223, determining the target humidity correction value based on the temperature difference between the dew point temperature value and the current coil temperature of the heat exchanger and a target correction coefficient; wherein the target correction coefficient is negatively correlated with the operating time of the target device in the current operating mode.

[0133] Here, the current operating mode is an operating mode capable of reducing the ambient humidity in the target space, such as a cooling mode or a dehumidification mode.

[0134] Here, the target correction coefficient is negatively correlated with the working time of the target device in the current working mode, that is, the longer the working time of the target device in the current working mode, the smaller the target correction coefficient; the shorter the working time of the target device in the current working mode, the larger the target correction coefficient.

[0135] The target correction coefficient may have a value range of greater than or equal to 0 and less than or equal to 0.75.

[0136] Specifically, based on the working time of the target device in the current working mode, the target correction coefficient is calculated according to a preset formula, and the target humidity correction value is determined based on the product of the temperature difference between the dew point temperature value and the current coil temperature of the heat exchanger and the target correction coefficient.

[0137] In some examples, the target humidity correction value may be determined as a product of a temperature difference between the dew point temperature value and the current coil temperature of the heat exchanger and a target correction coefficient.

[0138] In this embodiment, taking into account that the ambient humidity value in the target space will decrease as the cooling operation time or dehumidification operation time of the target device increases, the target humidity correction value is determined by combining the temperature difference between the dew point temperature value and the current coil temperature of the heat exchanger and the target correction coefficient that is negatively correlated with the working time of the target device in the current working mode. In this way, the deviation between the ambient humidity corrected based on the target humidity correction value and the actual humidity value can be smaller, thereby further improving the accuracy of controlling the target device.

[0139] In some embodiments, as Figure 4 As shown, based on Figure 3 , the method may further include:

[0140] S221, determining the time difference between a first preset time length and the working time of the target device in the current working mode; wherein, the first preset time length is: the time length required for the air duct of the target device to reach a dry state under the drive of the internal circulation fan of the target device.

[0141] The working time of the target device in the current working mode is the time difference between the current moment and the start moment of the target device in the current working mode.

[0142] Among them, the first preset time can be understood as: when the target device operates in internal circulation mode (without cooling / heating / humidification function, only filtering and purifying the indoor air) to dry the air duct, the time required for the air duct of the target device to reach a dry state.

[0143] In some examples, the first moment when the target device enters the internal circulation mode can be determined, and the second moment when the air duct reaches a dry state under the drive of the internal circulation fan of the target device can be determined, and the time difference between the second moment and the first moment is determined as the first preset duration.

[0144] The first preset duration may be determined in advance through experimental data.

[0145] For example, when the target device is operating in internal circulation mode to dry the air duct, the detection value of the first humidity sensor at the air duct inlet and the detection value of the second humidity sensor at the air duct outlet can be compared in real time. When the detection value of the first humidity sensor and the detection value of the second humidity sensor are the same, it is determined that the air duct of the target device has reached a dry state. Here, the detection value of the first humidity sensor can be obtained by detecting the first humidity sensor set at the air duct inlet, and the detection value of the second humidity sensor can be obtained by detecting the second humidity sensor set at the air duct outlet.

[0146] In addition, in order to improve the accuracy of the first preset time, for each target device among multiple target devices, the time required for the air duct of the target device to reach a dry state under the drive of the internal circulation fan of the target device can be first determined, and then the average time required for the air duct of the multiple target devices to reach a dry state can be determined as the first preset time.

[0147] S222: Determine the target correction coefficient according to a ratio between the time difference and a second preset time length, wherein the first preset time length is smaller than the second preset time length.

[0148] The ratio between the first preset duration and the second preset duration is within a preset range, which may be, for example, 0.7 to 0.8. Here, the ratio between the first preset duration and the second preset duration may be 0.75. For example, when the first preset duration is 2400 seconds, the second preset duration may be 3200 seconds.

[0149] In one example, the target correction coefficient may be determined as a ratio of a time difference between a first preset duration and a working duration of the target device in the current working mode to a second preset duration.

[0150] In this embodiment, since the first time length is the time length required for the air duct of the target device to reach a dry state under the drive of the internal circulation fan of the target device, the target correction coefficient is determined in combination with the working time of the target device in the current working mode, the first preset time length and the second preset time length that is greater than the first preset time length, and the humidity correction is performed based on the target humidity correction value determined based on the target correction coefficient. This can further reduce the deviation between the corrected ambient humidity and the actual humidity value, thereby making the corrected ambient humidity closer to the actual humidity value.

[0151] In some embodiments, in step S222, determining the target correction coefficient based on the ratio between the time difference and the second preset duration may include:

[0152] The ratio of the time difference to the second preset duration is determined as an alternative correction coefficient; and the target correction coefficient is determined according to the maximum value of the alternative correction coefficient and the preset correction coefficient.

[0153] The preset correction coefficient may be determined based on different air duct structures of the target equipment and in combination with experimental data.

[0154] Here, the value range of the preset correction coefficient is 0 to 0.75. For example, taking a wall-mounted air conditioner as the target device, the value of the preset correction coefficient may be 0.25.

[0155] Specifically, the candidate correction coefficient can be compared with the preset correction coefficient, and the correction coefficient with the larger value can be selected as the target correction coefficient.

[0156] In this embodiment, considering that the operating time of the target device in the current working mode (for example, cooling mode or dehumidification mode) exceeds a certain time (for example, a first preset time), the target correction coefficient determined according to the time difference between the first preset time and the working time of the target device in the current working mode will be 0, resulting in a target humidity correction value of 0. Therefore, in order to ensure that the ambient humidity in the target space can be corrected, in this embodiment, the ratio between the time difference and the second preset time and the maximum value of the preset correction coefficients is determined as the target correction coefficient, which can ensure the humidity correction during the entire working process of the target device in the current working mode.

[0157] In some embodiments, in step S223, determining the target humidity correction value based on the temperature difference between the dew point temperature value and the current coil temperature of the heat exchanger and the target correction coefficient may include:

[0158] The product of the temperature difference and the target correction coefficient is determined as an alternative humidity correction value; and the target humidity correction value is determined according to the maximum value of the alternative humidity correction value and the preset humidity correction value.

[0159] The preset humidity correction value can be set according to actual application needs, and the preset humidity correction value can be set to 0.

[0160] Specifically, the preset humidity correction value and the candidate humidity correction value may be compared, and the humidity correction value with the larger value may be selected as the target humidity correction value.

[0161] In this embodiment, considering that the heat exchanger coil temperature is greater than the dew point temperature value (for example, after exiting the dehumidification mode or the cooling mode), that is, the temperature value between the dew point temperature value and the heat exchanger coil temperature is less than 0, there is no need to perform ambient humidity correction. At this time, the target humidity correction value is determined based on the maximum value of the preset humidity correction value and the product of the temperature difference and the target correction coefficient, thereby ensuring the reliability of the target humidity correction value.

[0162] In some embodiments, as Figure 5 As shown, in the above step S300, the step of correcting the first ambient humidity according to the target humidity correction value to obtain the second ambient humidity may include:

[0163] S310: Determine a first candidate ambient humidity according to the sum of the target humidity correction value and the first ambient humidity.

[0164] Specifically, the sum of the target humidity correction value and the first ambient humidity may be determined as the first candidate ambient humidity.

[0165] S320, determining the second ambient humidity according to the minimum value of the first alternative ambient humidity and the second alternative ambient humidity; wherein the second alternative ambient humidity is: the ambient humidity in the target space when the target device enters the current working mode.

[0166] Specifically, the first candidate ambient humidity and the second candidate ambient humidity may be compared, and the ambient humidity value with the smaller value may be selected as the second ambient humidity.

[0167] In this embodiment, taking into account that the ambient humidity value in the target space will decrease with the increase of the cooling operation time or the dehumidification time of the target device, the second ambient humidity is determined based on the minimum value of the first alternative ambient humidity and the second alternative ambient humidity. In this way, when the target device fails to operate in the current working mode, it can effectively suppress the use of humidity values that deviate greatly from the actual value of the ambient humidity to participate in the operation of controlling the target device, thereby improving the reliability and accuracy of controlling the target device.

[0168] Next, taking an air conditioner as an example, the control method of the target device provided by the present disclosure is described in combination with specific embodiments.

[0169] Specifically, the control method may include the following steps:

[0170] Step 1: When the following conditions are met, enter the humidity compensation calculation (i.e., humidity correction).

[0171] Condition 1: The air conditioning mode is in cooling or dehumidification mode;

[0172] Condition 2: Compressor frequency F≠0;

[0173] Step 2: Calculate the dew point temperature.

[0174] The dew point temperature can be calculated using the following formula:

[0175] T dew =A+B*T in +C*U+D*T in 2 -E*U 2 +F*T in *U in ;

[0176] Among them, T dew is the dew point temperature value, T in is the current ambient temperature in the target space, U is the first ambient humidity in the target space (ie, the relative humidity detection value in the target space), and the values of A to F are all preset constants.

[0177] In specific applications, the dew point temperature value can be calculated according to the following formula:

[0178] T dew =-30.3843+0.7012*T in +61.2194*U+0.0005*T in 2 -32.8593*U 2 +0.3250*T in *U.

[0179] Step 3. Calculation of humidity compensation value

[0180] U cal =min(U+C,U 初始 );

[0181] C=max((T dew -T tube_in )*α,0);

[0182] α=max((t1-t) / t2,C min )

[0183] Among them, U cal is the relative humidity after compensation;

[0184] C is the humidity correction value, U 初始 The ambient humidity in the target space at the time of humidity compensation calculation;

[0185] T tube_inis the heat exchanger coil temperature in the target space (unit: °C);

[0186] α is the time correction coefficient; t1 is the first preset time length, t2 is the second preset time length, the value of t1 can be 2400, and the value of t2 can be 3200;

[0187] C min To preset the correction coefficient, it can be determined according to the different air duct structures of the air conditioner and combined with experimental data, C min The value range is 0 to 0.75. For example, for a wall-mounted air conditioner, C min The default value may be 0.25.

[0188] t is the working time of the cooling / dehumidification function, which starts from the moment the compressor is turned on. When the compressor stops, the t value is reset to zero.

[0189] In the disclosed embodiments, when the air conditioner is operating in cooling or dehumidification mode, the dew point temperature is calculated based on the ambient temperature and humidity within the target space, and a humidity correction value for the ambient humidity is determined based on the dew point temperature and the coil temperature within the target space. This allows the ambient humidity, corrected based on the correction value, to more closely approximate the actual humidity value. Thus, by controlling the air conditioner's operation based on the corrected ambient humidity, the frequent on / off switching of the target device caused by the air conditioner's dehumidification function being repeatedly turned on and off can be effectively reduced, thereby reducing device energy consumption. Furthermore, the accuracy of the dehumidification control and the dehumidification effect of the target device can be improved.
