[0025] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements.

[0026] In the related art, during the dehumidification process of the air conditioner, even if the indoor temperature reaches the target, the air conditioner will continue to cool in order to reach the humidity, resulting in an unbalanced regulation of the room air temperature (hereinafter referred to as the indoor temperature) and the room air humidity (hereinafter referred to as the indoor humidity). For example, the indoor temperature may reach the target temperature but the indoor humidity may not reach the target, resulting in continued dehumidification and cooling, thus over-cooling. Similarly, excessive dehumidification may also cause the room air to be too dry, greatly reducing indoor comfort. In either case, the user experience of the air conditioner will be reduced.

[0027] In response to the above technical problems, the embodiments of the present disclosure provide an air conditioning control method, device and electronic device. The air conditioner is intelligently controlled to make the indoor temperature reach the target temperature and the indoor humidity reach the target humidity when the indoor air reaches the temperature but not the humidity, or reaches the humidity but not the temperature. This can balance the changes in indoor air temperature and humidity, improve the user experience of the air conditioner, and control the air conditioner based on a control strategy corresponding to the target state, which can also improve the accuracy of controlling the air conditioner.

[0028] Figure 1 is a flow chart of an air conditioning control method according to an exemplary embodiment. Figure 1 As shown, the method can be applied to an electronic device, which can be an air conditioner or an Internet of Things device connected to the air conditioner. The method may include the following steps: In step S101, in response to the air conditioner operating in a dehumidification mode, the indoor temperature and the indoor humidity are acquired.

[0029] In this embodiment, the air conditioner can operate in a dehumidification mode in response to receiving a dehumidification instruction. Optionally, the dehumidification instruction can be triggered by a user through a remote control device, or can be generated by an electronic device based on indoor humidity. The remote control device can be a traditional air conditioner remote control, or can be an electronic device such as a mobile phone, a tablet, or a smart wearable device that can be used to control the air conditioner.

[0030] In a possible implementation, when the air conditioner operates in a dehumidification mode, the indoor temperature and the indoor humidity may be periodically acquired.

[0031] In step S102, based on the indoor temperature and the indoor humidity, it is determined whether the indoor environment has reached the target state.

[0032] The target state is any one of a first state and a second state, the first state indicates that the indoor temperature reaches the target temperature and the indoor humidity does not reach the target humidity, and the second state indicates that the indoor humidity reaches the target humidity and the indoor temperature does not reach the target temperature.

[0033] In this embodiment, the first state and the second state may be preconfigured so that after the electronic device acquires the indoor temperature and the indoor humidity, it may determine whether the first state or the second state is reached based on the indoor temperature and the indoor humidity.

[0034] If the indoor temperature reaches the target temperature, but the indoor humidity does not reach the target humidity, it can be determined that the first state is reached; if the indoor humidity reaches the target humidity, but the indoor temperature does not reach the target temperature, it can be determined that the second state is reached. When either the first state or the second state is reached, it can be determined that the target state is reached. If the indoor humidity does not reach the target humidity, and the indoor temperature does not reach the target temperature, it can be determined that the target state is not reached.

[0035] The indoor temperature reaching the target temperature can be understood as the difference between the indoor temperature and the target temperature being less than a set threshold. For example, the threshold can be set to 0, so that the indoor temperature reaching the target temperature can be understood as the indoor temperature being the same as the target temperature.

[0036] The indoor humidity reaching the target humidity can be understood as the difference between the indoor humidity and the target humidity being less than a set threshold. For example, the threshold can be set to 0, so that the indoor humidity reaching the target humidity can be understood as the indoor humidity being the same as the target humidity.

[0037] In step S103, when it is determined that the indoor environment has reached the target state, the air conditioner is controlled based on a control strategy corresponding to the target state so that the indoor temperature reaches the target temperature and the indoor humidity reaches the target humidity.

[0038] In this embodiment, when the target state is reached, dehumidification will not be stopped, but the air conditioner will continue to be more accurately controlled based on the control strategy corresponding to the target state so that the indoor temperature reaches the target temperature and the indoor humidity reaches the target humidity.

[0039] It should be noted that when the electronic device is the air conditioner itself, the air conditioner can control the components in the air conditioner according to the control instructions generated by its own controller. When the electronic device is an Internet of Things device different from the air conditioner, the Internet of Things device can generate control instructions and send them to the air conditioner to control the components in the air conditioner.

[0040] By adopting the above method, the electronic device can first obtain the indoor temperature and indoor humidity in response to the air conditioner running in the dehumidification mode, and then determine whether the indoor environment has reached the target state based on the indoor temperature and indoor humidity, and control the air conditioner based on the control strategy corresponding to the target state when it is determined that the indoor environment has reached the target state. By continuing to control the air conditioner when the indoor air is at the temperature but not the humidity or at the humidity but not the temperature, so that the indoor temperature reaches the target temperature and the indoor humidity reaches the target humidity, the indoor air temperature and humidity changes can be balanced, and the user's experience of using the air conditioner can be improved. In addition, by controlling the air conditioner based on the control strategy corresponding to the target state, the accuracy of controlling the air conditioner can also be improved.

[0041] Among them, in step S103, there may be multiple scenarios for the indoor air to reach the target state.

[0042] In some scenarios, after the user starts the dehumidification mode through the remote control device, the user can set the target humidity and target temperature on the remote control device according to their needs. When the target temperature set by the user is the same as the indoor temperature, but the set target humidity is different from the indoor humidity, the air conditioner enters the dehumidification mode and it can be determined that the first state is reached. When the target humidity set by the user is the same as the indoor humidity, but the set target temperature is different from the indoor temperature, the air conditioner enters the dehumidification mode and it can be determined that the second state is reached.

[0043] In other scenarios, when the target temperature set by the user is different from the indoor temperature, and the target humidity set is different from the indoor humidity, after the air conditioner enters the dehumidification mode, it can first perform a rapid dehumidification operation to lower the indoor temperature and indoor humidity. After a certain period of rapid dehumidification operation, the target state can be reached.

[0044] Therefore, in a possible implementation, the method of the embodiment of the present disclosure may further include the following step of performing a rapid dehumidification operation: when it is determined that the indoor environment has not reached the target state, determining a first control parameter, the first control parameter including a first compressor frequency and a first fan gear; and controlling the air conditioner based on the first control parameter. The first control parameter may be understood as a control parameter corresponding to when the air conditioner performs a rapid dehumidification operation.

[0045] Considering that the lower the fan speed in the air conditioner, the lower the temperature of the heat exchanger coil, the better the dehumidification effect, and the higher the frequency of the compressor in the air conditioner, the better the cooling effect, therefore, in this embodiment, consider controlling the two parameters of the compressor frequency and the fan gear position to quickly cool down and dehumidify.

[0046] In a possible implementation, in order to achieve temperature reduction, the compressor frequency may be determined based on the indoor temperature and the target temperature.

[0047] In one possible implementation, determining the first control parameter may include the following steps: obtaining a first target temperature difference between the indoor temperature and the target temperature; calculating a first compressor frequency corresponding to the first target temperature difference based on a first corresponding relationship between the temperature difference and the compressor frequency, and determining the compressor frequency of the air conditioner as the first compressor frequency.

[0048] In this embodiment, a first correspondence between the temperature difference and the compressor frequency is pre-configured. In this way, after obtaining the first target temperature difference between the indoor temperature and the target temperature (i.e., the difference between the indoor temperature and the target temperature), the first compressor frequency in the first control parameter can be determined based on the first correspondence. In this way, the compressor of the air conditioner can be subsequently controlled according to the first compressor frequency.

[0049] In a possible implementation, based on a first correspondence between temperature difference and compressor frequency, calculating the first compressor frequency corresponding to the first target temperature difference may include the following steps: when the first target temperature difference is greater than or equal to the first temperature difference threshold, determining the first compressor frequency corresponding to the first target temperature difference as the first preset frequency; when the first target temperature difference is greater than or equal to the second temperature difference threshold and less than the first temperature difference threshold, determining the first compressor frequency corresponding to the first target temperature difference as the second preset frequency; when the first target temperature difference is greater than or equal to the third temperature difference threshold and less than the second temperature difference threshold, determining the first compressor frequency corresponding to the first target temperature difference as the third preset frequency; wherein the first preset frequency, the second preset frequency and the third preset frequency decrease in sequence, and the first temperature difference threshold, the second temperature difference threshold and the third temperature difference threshold decrease in sequence.

[0050] In this embodiment, when the first target temperature difference is small, the cooling capacity required to cool down from the indoor temperature to the target temperature is small, so a relatively small compressor frequency can be set. When the first target temperature difference is large, the cooling capacity required to cool down from the indoor temperature to the target temperature is large, so a relatively large compressor frequency can be set. In this way, resources can be saved and noise can be reduced while meeting the air cooling demand. In addition, by setting the first corresponding relationship to include a plurality of temperature difference thresholds and compressor frequency corresponding relationships, the accuracy of compressor control can be improved.

[0051] In an example, the first temperature difference threshold can be set to 4°C, the second temperature difference threshold can be set to 2°C, the third temperature difference threshold can be set to 0°C, the first preset frequency can be set to 84hz, the second preset frequency can be set to 20hz, and the third preset frequency can be set to 8~10hz.

[0052] In a possible implementation, determining the first control parameter may further include the following steps: determining the first fan gear as the lowest speed gear of the fan. Here, by setting the first fan gear to the lowest speed gear of the fan, the dehumidification effect can be improved and the indoor humidity can be quickly reduced.

[0053] Exemplarily, when the fan has multiple preset speed gears of low wind speed, medium wind speed and high wind speed, the first fan gear can be set to low wind speed.

[0054] It is understandable that, when the target state is not reached, the air conditioner can be controlled by the first control parameter determined in the above manner so that the indoor air can quickly reach the target state. Next, after the indoor air reaches the target state, the process of controlling the air conditioner based on the control strategy corresponding to the target state is described in detail.

[0055] In one possible implementation, the target state may be the first state. In this case, in step S103, when it is determined that the indoor environment has reached the target state, the air conditioner is controlled based on a control strategy corresponding to the target state, which may include the following steps: when it is determined that the indoor environment has reached the first state, second control parameters are determined, the second control parameters including a second compressor frequency and a second fan gear; and the air conditioner is controlled based on the second control parameters.

[0056] The second control parameter may be understood as a control parameter of the air conditioner when reaching the first state.

[0057] The target dew point temperature may be calculated based on the indoor temperature before running the dehumidification mode and the target humidity.

[0058] In one possible implementation, the target dew point temperature is calculated by the following formula:

[0059]

[0060] in, represents the target dew point temperature, It represents an intermediate parameter in the calculation process, T represents the temperature in degrees Celsius, and RH represents the relative humidity of the air. Indicates the indoor temperature before running the dehumidification mode. Indicates the target humidity, and is the Magnus coefficient, For example, it can be taken as 17.27, It can be taken as 237.7.

[0061] In this embodiment, since the indoor temperature has reached the target temperature when the first state is reached, in order to ensure that the air conditioner can continue to dehumidify after reaching the target temperature, it is necessary to ensure that the heat exchanger coil temperature is lower than the dew point temperature. At the same time, the compressor frequency (i.e., the second compressor frequency) is no longer determined based on the difference between the indoor temperature and the target temperature (i.e., the first target temperature difference), but the second control parameter is determined instead, and the operation of the air conditioner is controlled based on the second control parameter. The second control parameter includes the second compressor frequency.

[0062] In one possible implementation, determining the second control parameter may include the following steps: obtaining the heat exchanger coil temperature, indoor humidity, target humidity and target dew point temperature of the air conditioner, and calculating the second target temperature difference between the target dew point temperature and the heat exchanger coil temperature; calculating the target humidity difference between the indoor humidity and the target humidity; calculating the second compressor frequency corresponding to the second target temperature difference based on the second corresponding relationship between the temperature difference and the compressor frequency and the target humidity difference, and determining the compressor frequency of the air conditioner as the second compressor frequency.

[0063] In this embodiment, the second correspondence between the temperature difference and the compressor frequency can be preconfigured, so that after obtaining the second target temperature difference between the target dew point temperature and the heat exchanger coil temperature (i.e., the difference between the target dew point temperature and the heat exchanger coil temperature), and obtaining the target humidity difference between the indoor humidity and the target humidity (the difference between the indoor humidity and the target humidity), the second compressor frequency in the second control parameter can be determined based on the second correspondence and the target humidity difference, so that the compressor of the air conditioner can be controlled according to the second compressor frequency. In this way, the indoor cooling capacity can be reduced on the basis of ensuring dehumidification, preventing the indoor temperature from continuing to drop, and at the same time, resources can be saved.

[0064] In a possible implementation, based on the second corresponding relationship between the temperature difference and the compressor frequency and the target humidity difference, calculating the second compressor frequency corresponding to the second target temperature difference, and determining the compressor frequency of the air conditioner as the second compressor frequency may include the following steps: When the target humidity difference is greater than the first humidity threshold and the second target temperature difference is greater than or equal to the fourth temperature difference threshold, the second compressor frequency is determined to be 0; when the target humidity difference is greater than the first humidity threshold and the second target temperature difference is greater than or equal to the fifth temperature difference threshold and less than the fourth temperature difference threshold, the second compressor frequency is determined to be the fourth preset frequency; when the target humidity difference is greater than the first humidity threshold and the second target temperature difference is greater than or equal to the sixth temperature difference threshold and less than the fifth temperature difference threshold, the second compressor frequency is determined to be the fifth preset frequency; when the target humidity difference is less than or equal to the first humidity threshold and the second target temperature difference is greater than or equal to the seventh temperature difference threshold and less than the sixth temperature difference threshold, the second compressor frequency is determined to be the fourth preset frequency; when the second target temperature difference is less than 0, the second compressor frequency is determined to be the sixth preset frequency; wherein the fourth preset frequency, the fifth preset frequency and the sixth preset frequency increase in sequence.

[0065] When the second target temperature difference is less than 0, it means that the heat exchanger coil temperature is greater than the target dew point temperature, and dehumidification cannot be performed at this time. Therefore, the second compressor frequency can be determined to be a larger sixth preset frequency to quickly reduce the heat exchanger coil temperature to below the target dew point temperature and continue dehumidification.

[0066] Here, when the second target temperature difference is greater than or equal to 0, two situations are firstly divided into two situations: the target humidity difference is greater than the first humidity threshold, and the target humidity difference is less than or equal to the first humidity threshold.

[0067] The target humidity difference is greater than the first humidity threshold, indicating that the indoor humidity is far from the target humidity difference. At this time, when the second target temperature difference is greater than or equal to the fourth temperature difference threshold, it means that the heat exchanger coil temperature is far lower than the target dew point temperature, the heat exchanger coil temperature is low enough, and the cooling capacity is sufficient. To prevent the heat exchanger coil temperature from continuing to decrease, the compressor can be controlled to stop, that is, the second compressor frequency is determined to be 0.

[0068] Further, when the second target temperature difference is greater than or equal to the fifth temperature difference threshold and less than the fourth temperature difference threshold, or, when the second target temperature difference is greater than or equal to the sixth temperature difference threshold and less than the fifth temperature difference threshold, considering that the cooling capacity may be insufficient, in order to ensure that the cooling capacity is maintained at a more appropriate level, you can consider starting the compressor, that is, setting the compressor frequency to the fourth preset frequency or the fifth preset frequency, and setting the fourth preset frequency lower than the fifth preset frequency, so that the compressor frequency can be appropriately increased according to the lack of cooling capacity.

[0069] The target humidity difference is less than the first humidity threshold, indicating that the indoor humidity is close to the target humidity difference, and the cooling capacity required for dehumidification is small. Further, when the second target temperature difference is greater than or equal to the seventh temperature difference threshold and less than the sixth temperature difference threshold, it means that there is still cooling capacity left, but the cooling capacity is too small. At this time, the compressor frequency can be set to a smaller fourth preset frequency to maintain a smaller cooling capacity output until the indoor humidity is finally reduced to the target humidity.

[0070] In a possible implementation, when the second target temperature difference is greater than or equal to the sixth temperature difference threshold, it indicates that the remaining cooling capacity is relatively large. In this case, the second compressor frequency may be set to 0.

[0071] In addition, by setting the second correspondence to include a plurality of correspondences between temperature difference thresholds and compressor frequencies, the accuracy of compressor control can be improved.

[0072] In an example, the fourth temperature difference threshold can be set to 5°C, the fifth temperature difference threshold can be set to 3°C, the sixth temperature difference threshold can be set to 1°C, the seventh temperature difference threshold can be set to 0°C, the fourth preset frequency can be the same as the third preset frequency, for example, the fourth preset frequency can be set to 8~10hz, the fifth preset frequency can be the same as the second preset frequency, for example, the fifth preset frequency can be set to 20hz, and the sixth preset frequency can be the same as the first preset frequency, for example, the sixth preset frequency can be set to 84hz.

[0073] In a possible implementation manner, determining the second control parameter may further include the following steps: determining the second fan gear as the lowest speed gear of the fan.

[0074] In this embodiment, when the indoor humidity does not reach the target humidity, the second fan gear can also be set to the lowest speed gear of the fan to maintain a faster dehumidification effect and quickly reduce the indoor humidity.

[0075] Exemplarily, when the fan has multiple preset speed gears of low wind speed, medium wind speed and high wind speed, the second fan gear may be set to low wind speed.

[0076] In one possible implementation, the second control parameter also includes the angle of the air guide plate in the air conditioner. In this case, determining the second control parameter may also include the following steps: obtaining the heat exchanger coil temperature and the target dew point temperature of the air conditioner; calculating the second target temperature difference between the target dew point temperature and the heat exchanger coil temperature; based on the correspondence between the temperature difference and the air guide plate angle, calculating the target air guide plate angle corresponding to the second target temperature difference, and determining the angle of the air guide plate in the air conditioner as the target air guide plate angle.

[0077] In this embodiment, considering that the indoor temperature has reached the target temperature, the user does not want a large amount of cold air to flow out for a long time. In this case, the target air guide plate angle corresponding to the second target temperature difference can be calculated based on the correspondence between the temperature difference and the air guide plate angle, and the angle of the air guide plate in the air conditioner is determined as the target air guide plate angle to avoid the cold air from the air conditioner blowing directly on the user, thereby improving the user experience.

[0078] In a possible implementation, when the second target temperature difference is greater than or equal to the fifth temperature difference threshold, the second target temperature difference is inversely correlated with the angle of the air guide plate, and when the second target temperature difference decreases and reaches the fifth temperature difference threshold, the air guide plate reaches the maximum angle. That is, when the second target temperature difference is greater than or equal to the fifth temperature difference threshold, as the second target temperature difference decreases, the air guide plate angle increases, and when the second target temperature difference decreases and reaches the fifth temperature difference threshold, the air guide plate reaches the maximum angle, and when the second target temperature difference is less than the fifth temperature difference threshold, the air guide plate angle is set to the maximum angle to avoid direct air blowing by the air conditioner and reduce the outflow of cold.

[0079] Exemplarily, when the second target temperature difference is greater than or equal to 5°C, the air deflector angle can be set to 30 degrees, when the second target temperature difference is greater than or equal to 3°C and less than 5°C, the air deflector angle can be set to 60 degrees, and when the second target temperature difference is less than 3°C, the air deflector angle can be set to 90 degrees.

[0080] In one possible implementation, the target state may be the second state. In this case, in step S103, when it is determined that the indoor environment has reached the target state, the air conditioner is controlled based on a control strategy corresponding to the target state, which may include the following steps: when it is determined that the indoor environment has reached the second state, a third target temperature difference between the indoor temperature and the target temperature is calculated; based on a third corresponding relationship between the temperature difference and the compressor frequency, the heat exchanger coil temperature and the target dew point temperature, a third compressor frequency corresponding to the third target temperature difference is calculated, and the compressor frequency of the air conditioner is determined as the third compressor frequency; based on the third compressor frequency, the air conditioner is controlled.

[0081] The third compressor frequency may be understood as a frequency control parameter of the air conditioner when reaching the second state.

[0082] In this embodiment, since the indoor humidity has reached the target humidity when the second state is reached, in order to ensure that the air conditioner can continue to cool down after reaching the target humidity, it is necessary to ensure that the heat exchanger coil temperature is higher than the dew point temperature. At the same time, the compressor frequency (i.e., the third compressor frequency) is no longer determined solely based on the difference between the indoor temperature and the target temperature (i.e., the first target temperature difference), but the third compressor frequency is controlled based on the target dew point temperature, the heat exchanger coil temperature, the indoor temperature and the target temperature. In this way, the dehumidification effect can be reduced while ensuring cooling, and the indoor humidity can be prevented from continuing to drop. At the same time, resources can be saved.

[0083] In this embodiment, a third correspondence between the temperature difference and the compressor frequency can be pre-configured. In this way, after obtaining the third target temperature difference between the indoor temperature and the target temperature (i.e., the difference between the indoor temperature and the target temperature), and obtaining the heat exchanger coil temperature and the target dew point temperature, the third compressor frequency can be determined based on the third correspondence, the heat exchanger coil temperature and the target dew point temperature. In this way, the compressor of the air conditioner can be subsequently controlled according to the third compressor frequency.

[0084] In a possible implementation, based on the third corresponding relationship between the temperature difference and the compressor frequency, the heat exchanger coil temperature and the target dew point temperature, calculating the third compressor frequency corresponding to the third target temperature difference may include the following steps: when the heat exchanger coil temperature is greater than the target dew point temperature and the third target temperature difference is greater than or equal to the eighth temperature difference threshold, determining the third compressor frequency to be the seventh preset frequency; when the heat exchanger coil temperature is greater than the target dew point temperature and the third target temperature difference is greater than or equal to the ninth temperature difference threshold and less than the eighth temperature difference threshold, determining the third compressor frequency to be the eighth preset frequency; when the heat exchanger coil temperature is greater than the target dew point temperature and the third target temperature difference is greater than or equal to the tenth temperature difference threshold and less than the ninth temperature difference threshold, determining the third compressor frequency to be the ninth preset frequency; when the heat exchanger coil temperature is less than or equal to the target dew point temperature, determining the third compressor frequency to be the ninth preset frequency; wherein the seventh preset frequency, the eighth preset frequency and the ninth preset frequency decrease in sequence.

[0085] Here, two situations are firstly distinguished: the heat exchanger coil temperature is greater than the target dew point temperature, and the heat exchanger coil temperature is less than or equal to the target dew point temperature.

[0086] In this embodiment, when the heat exchanger coil temperature is greater than the target dew point temperature, similar to the rapid dehumidification operation process, when the third target temperature difference is small, the cooling capacity required to cool from the indoor temperature to the target temperature is small, so a relatively small compressor frequency can be set, and when the third target temperature difference is large, the cooling capacity required to cool from the indoor temperature to the target temperature is large, so a relatively large compressor frequency can be set, so that resources can be saved and noise can be reduced while meeting the air cooling demand. In addition, by setting the third corresponding relationship to include a plurality of temperature difference thresholds and compressor frequency corresponding relationships, the accuracy of compressor control can be improved.

[0087] In one possible embodiment, the eighth temperature difference threshold may be the same as the first temperature difference threshold, for example, the eighth temperature difference threshold may be set to 4°C, the ninth temperature difference threshold may be the same as the second temperature difference threshold, for example, the ninth temperature difference threshold may be set to 2°C, the tenth temperature difference threshold may be the same as the third temperature difference threshold, for example, the tenth temperature difference threshold may be set to 0°C, the seventh preset frequency may be the same as the first preset frequency, for example, the seventh preset frequency may be set to 84hz, the eighth preset frequency may be the same as the second preset frequency, for example, the eighth preset frequency may be set to 20hz, and the ninth preset frequency may be the same as the third preset frequency, for example, the ninth preset frequency may be set to 8~10hz.

[0088] The heat exchanger coil temperature is less than or equal to the target dew point temperature, and the air conditioner cannot continue to cool down. Therefore, when the heat exchanger coil temperature is less than or equal to the target dew point temperature, the third compressor frequency can be set to a ninth preset frequency. By setting the third compressor frequency to the ninth preset frequency, the coil temperature is increased until the coil temperature is greater than the target dew point temperature, thereby preventing the air conditioner from continuing to dehumidify.

[0089] Here, setting the third compressor frequency to the ninth preset frequency instead of setting it to 0 can avoid the compressor from starting and stopping back and forth, saving resources, and at the same time, the purpose of continuing to cool down can be achieved by starting the compressor.

[0090] In a possible implementation, when the second state is reached, no additional control may be performed on the fan gear and the air guide plate angle, and the fan gear and the air guide plate angle before entering the dehumidification mode may be used, or may be controlled by the user according to actual needs.
