[0059] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0064] Figure 4 is a block diagram of a device for air conditioning control according to an exemplary embodiment. DETAILED DESCRIPTION

[0065] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0066] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0067] Figure 1 FIG. 1 is a flow chart of an air conditioning control method according to an exemplary embodiment. Figure 1 As shown, the method includes the following steps.

[0068] In step S101, if it is determined that the air duct of the air conditioner needs to be dried, the outdoor ambient temperature of the air conditioner is obtained.

[0069] When it is determined that the air duct of the air conditioner needs to be dried, the outdoor ambient temperature of the air conditioner can be obtained. A sensor can be provided in the outdoor unit of the air conditioner to obtain the outdoor ambient temperature of the air conditioner. For example, the sensor can be a temperature sensor.

[0070] In step S102, the drying program to be executed is determined according to the acquired outdoor ambient temperature. The drying program includes a first drying program and a second drying program. When the first drying program is executed, the air conditioner is in a cooling state or a dehumidifying state. When the second drying program is executed, the air conditioner is in a heating state.

[0071] The drying program may include a first drying program and a second drying program. When the first drying program is executed, the air conditioner is in a cooling state or a dehumidifying state, and the refrigerant flows to the outdoor unit heat exchanger through the compressor, and then flows to the indoor unit heat exchanger through the outdoor unit heat exchanger. If the outdoor ambient temperature is low, the heat loss of the refrigerant at the outdoor unit heat exchanger is high, resulting in a low temperature at the indoor unit heat exchanger, a long drying time, and a low drying efficiency. When the second drying program is executed, the air conditioner is in a heating state, and the refrigerant flows to the indoor unit heat exchanger through the compressor, and then flows to the outdoor unit heat exchanger through the indoor heat exchanger. In this way, even when the outdoor ambient temperature is low, the temperature at the indoor unit heat exchanger is still high, which can meet the drying requirements. Therefore, after obtaining the outdoor ambient temperature of the air conditioner, the drying program to be executed can be determined according to the obtained outdoor ambient temperature. For example, if the obtained outdoor ambient temperature is high, it can be determined to execute the first drying program; if the obtained outdoor ambient temperature is low, it can be determined to execute the second drying program.

[0072] In step S103, the determined drying program is executed to dry the air duct of the air conditioner.

[0073] After determining the drying program to be executed, the drying program can be executed to dry the air duct of the air conditioner. For example, a first drying program can be executed to dry the air duct of the air conditioner, and a second drying program can be executed to dry the air duct of the air conditioner.

[0074] Through the above technical solution, when it is determined that the air duct of the air conditioner needs to be dried, the outdoor ambient temperature of the air conditioner is obtained, and the drying program to be executed is determined according to the obtained outdoor ambient temperature. The drying program includes a first drying program and a second drying program. When the first drying program is executed, the air conditioner is in a cooling state or a dehumidifying state. When the second drying program is executed, the air conditioner is in a heating state, and the determined drying program is executed to dry the air duct of the air conditioner. In this way, when the outdoor temperature is low, the air conditioner is controlled to be in a heating state to dry the air duct of the air conditioner, thereby improving the drying efficiency; when the outdoor temperature is high, the air conditioner is controlled to be in a cooling or dehumidifying state, and the heat loss of the refrigerant is low, saving the energy consumption of the air conditioner. This solution executes different drying programs according to different outdoor temperatures to dry the air duct of the air conditioner, taking into account both the drying efficiency and energy consumption, and has good flexibility.

[0075] In another embodiment, the above-mentioned determining the drying program to be executed according to the acquired outdoor ambient temperature includes:

[0076] If the acquired outdoor environment temperature is greater than a first temperature threshold, determining that the drying program to be executed is a first drying program;

[0077] If the acquired outdoor environment temperature is not greater than the first temperature threshold, it is determined that the drying program to be executed is the second drying program.

[0078] The first temperature threshold can be preset by the designer, for example, it can be 20° C. When the acquired outdoor ambient temperature is greater than the first temperature threshold, the outdoor ambient temperature is high, and when the first drying program is executed to dry the air duct of the air conditioner, the heat loss of the refrigerant when flowing through the outdoor unit heat exchanger is low, and the temperature at the indoor unit heat exchanger is high, which can meet the demand for drying the air duct of the air conditioner. Therefore, it can be determined that the drying program executed is the first drying program.

[0079] When the obtained outdoor ambient temperature is not greater than the first temperature threshold, the outdoor ambient temperature is low. If the first drying program is executed to dry the air duct of the air conditioner, the heat loss of the refrigerant at the outdoor unit heat exchanger is high, resulting in a low temperature at the indoor unit heat exchanger and low drying efficiency. If the second drying program is executed to dry the air duct of the air conditioner, it can still be guaranteed that the air duct of the air conditioner has a high drying efficiency. Therefore, it can be determined that the drying program executed is the second drying program.

[0080] In this embodiment, the drying program to be executed is determined by simple threshold comparison, and the data processing speed is fast and the reliability is high.

[0081] In yet another embodiment, in the case of determining to execute the first drying program, executing the determined drying program includes:

[0082] The four-way valve controlling the air conditioner is connected to the refrigeration flow path;

[0083] Control and close the air guide plate and internal fan of the air conditioner;

[0084] Controlling the opening degree of the expansion valve of the air conditioner to be at a first opening degree;

[0085] Controlling the compressor of the air conditioner to operate at a target operating frequency;

[0086] The outdoor fan of the air conditioner is controlled to run at a predetermined first speed.

[0087] The four-way valve of the air conditioner can control the connection state of the cooling flow path and the heating flow path of the air conditioner. The initial state of the four-way valve of the air conditioner can be controlled to connect the refrigeration circuit. After the refrigeration circuit is connected, the refrigerant flows through the outdoor unit heat exchanger, the expansion valve and the indoor unit heat exchanger in sequence through the compressor.

[0088] During the process of drying the air duct of the air conditioner, the temperature of the indoor unit heat exchanger and the air duct is high. If the air guide plate and the internal fan of the air conditioner are in the open state, the heat will flow into the room through the air outlet, giving the user a bad experience. Therefore, the internal fan and the air guide plate of the air conditioner can be controlled to be turned off.

[0089] The expansion valve of the air conditioner allows the medium-temperature and high-pressure refrigerant to become low-temperature and low-pressure wet steam through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve a cooling effect. The larger the opening of the expansion valve, the higher the temperature at the indoor unit heat exchanger, and the smaller the opening of the expansion valve, the lower the temperature of the indoor unit heat exchanger. The opening of the expansion valve can be controlled to be at a first opening, and the first opening can be pre-set by the designer, for example, it can be 480°. When the opening of the expansion valve is at the first opening, the opening of the expansion valve is larger, the temperature at the indoor unit heat exchanger is higher, and the drying effect is better.

[0090] When the outdoor ambient temperature is high, if the operating frequency of the air conditioner compressor is high, the operating state of the compressor may be unstable, so the air conditioner compressor may be controlled to operate at a lower target operating frequency, such as 50 Hz.

[0091] The higher the speed of the air conditioner's external fan, the higher the heat dissipated when the refrigerant flows through the outdoor unit heat exchanger, and the lower the temperature at the indoor unit heat exchanger; the lower the speed of the air conditioner's external fan, the lower the heat dissipated when the refrigerant flows through the outdoor unit heat exchanger, and the higher the temperature at the indoor unit heat exchanger. The first speed can be preset by the designer, for example, it can be 900r / min. The air conditioner's external fan can be controlled to run at a predetermined first speed. When the air conditioner's external fan runs at the predetermined first speed, the speed of the air conditioner's external fan is low, the temperature at the indoor unit heat exchanger is high, and the drying efficiency is high.

[0092] In yet another embodiment, in the case of determining to execute the first drying program, executing the determined drying program further includes:

[0093] When the duration of executing the first drying program reaches a predetermined first duration threshold, if the temperature of the indoor heat exchanger of the air conditioner is less than a predetermined second temperature threshold, the outdoor fan of the air conditioner is controlled to reduce the speed of operation;

[0094] When the duration of executing the first drying program reaches a first duration threshold, if the temperature of the indoor heat exchanger of the air conditioner is greater than a predetermined third temperature threshold, the outdoor fan of the air conditioner is controlled to increase the speed, and the second temperature threshold is less than the third temperature threshold;

[0095] If the duration of executing the first drying program is greater than the drying duration threshold, the control stops executing the first drying program.

[0096] The first duration threshold can be preset by the designer, for example, it can be 10 minutes. When the duration of executing the first drying program reaches the predetermined first duration threshold, and the temperature of the indoor unit heat exchanger of the air conditioner is less than the predetermined second temperature threshold, it can be considered that after the predetermined time of drying, the temperature of the indoor unit heat exchanger is still low. If the drying continues at this temperature, the drying time will be long and the drying efficiency will be low. Therefore, the temperature of the indoor unit heat exchanger can be increased to improve the drying efficiency. The air conditioner's external fan can be controlled to reduce the speed to increase the temperature of the indoor unit heat exchanger. For example, the air conditioner's external fan can be controlled to reduce 100r / min. The second temperature threshold can be preset by the designer, for example, it can be 50°C.

[0097] The third temperature threshold can be preset by the designer, for example, it can be 60°C. When the duration of executing the first drying program reaches the first duration threshold, and the temperature of the indoor heat exchanger of the air conditioner is greater than the predetermined third temperature threshold, it can be considered that after the predetermined time of drying, the temperature of the indoor heat exchanger is high, and it is necessary to reduce the temperature of the indoor heat exchanger to ensure safety. The air conditioner's external fan can be controlled to increase the speed to reduce the temperature of the indoor heat exchanger. For example, the air conditioner's external fan can be controlled to increase 200r / min.

[0098] When the execution time of the first drying program is greater than the drying time threshold, it can be considered that the condensed water in the air duct of the air conditioner has disappeared, and the drying of the air duct of the air conditioner can be stopped, so the execution of the first drying program can be stopped.

[0099] In this embodiment, by executing the first drying program, the air duct of the air conditioner can be dried reliably and effectively when the outdoor ambient temperature is high.

[0100] In yet another embodiment, in the case of determining to execute the second drying program, executing the determined drying program includes:

[0101] The four-way valve controlling the air conditioner is connected to the heating flow path;

[0102] Control and close the air guide plate of the air conditioner;

[0103] Controlling the opening degree of the expansion valve of the air conditioner to be at a second opening degree;

[0104] Controlling the compressor of the air conditioner to operate at a target operating frequency;

[0105] Control the air conditioner's internal fan to run at the lowest wind speed;

[0106] The outdoor fan of the air conditioner is controlled to run at a predetermined second speed.

[0107] First, the four-way valve of the air conditioner can be controlled to connect the heating circuit. After the heating circuit is connected, the refrigerant flows through the indoor heat exchanger, the expansion valve and the outdoor heat exchanger in sequence. In this way, since the refrigerant in a high-temperature and high-pressure state first flows through the indoor heat exchanger, even when the outdoor ambient temperature is low, the temperature of the indoor heat exchanger is still high, meeting the drying requirements.

[0108] The air guide plate of the air conditioner can be controlled to close to prevent the heat in the air duct from entering the room.

[0109] The second opening degree can be preset by the designer, for example, 300°. The opening degree of the expansion valve of the air conditioner can be controlled to be at the second opening degree. The second opening degree is smaller than the first opening degree.

[0110] The compressor of the air conditioner can be controlled to operate at a target operating frequency, for example, 80 Hz. The target operating frequencies of the compressor in the two drying programs can be different, and the target operating frequency in the first drying program can be lower than the target operating frequency in the second drying program.

[0111] Since the heating circuit of the air conditioner is connected, the high-temperature and high-pressure refrigerant of the compressor first flows through the indoor unit heat exchanger. The temperature of the indoor unit heat exchanger is relatively high, so the indoor fan can be controlled to run at the lowest wind speed (for example, the wind speed corresponding to 90r / min) to dissipate heat from the indoor unit heat exchanger and prevent the heat exchanger from being damaged by excessive temperature.

[0112] When the outdoor ambient temperature is low, the outdoor fan can be controlled to run at a lower second speed to reduce the heat dissipation efficiency of the outdoor unit and ensure that the temperature of the indoor unit heat exchanger meets the drying requirements. Therefore, the outdoor fan can be controlled to run at a predetermined speed (for example, 600r / min). The second speed is lower than the first speed.

[0113] In yet another embodiment, in the case of determining to execute the second drying program, executing the determined drying program further includes:

[0114] When the duration of executing the second drying program reaches a predetermined first duration threshold, if the temperature of the indoor heat exchanger of the air conditioner is less than a predetermined second temperature threshold, the opening of the expansion valve of the air conditioner is controlled to decrease;

[0115] When the duration of executing the second drying program reaches the first duration threshold, if the temperature of the indoor heat exchanger of the air conditioner is greater than a predetermined third temperature threshold, the opening of the expansion valve of the air conditioner is controlled to increase, and the second temperature threshold is less than the third temperature threshold;

[0116] If the duration of executing the second drying program is greater than the drying duration threshold, the control stops executing the second drying program.

[0117] When the duration of executing the second drying program reaches a predetermined first duration threshold, and if the temperature of the indoor heat exchanger of the air conditioner is less than a predetermined second temperature threshold, it can be considered that after the predetermined drying time, the temperature of the indoor heat exchanger is still low. If drying is continued at this temperature, the drying time is long and the drying effect is poor. Therefore, the temperature of the indoor heat exchanger can be increased to improve the drying efficiency. The opening of the expansion valve of the air conditioner can be controlled to decrease to increase the temperature of the indoor heat exchanger.

[0118] When the duration of executing the second drying program reaches the first duration threshold and the temperature of the indoor unit heat exchanger of the air conditioner is greater than the predetermined third temperature threshold, it can be considered that after the predetermined time of drying, the temperature of the indoor unit heat exchanger is high and it is necessary to lower the temperature of the indoor unit heat exchanger to ensure safety. Therefore, the opening of the expansion valve of the air conditioner can be controlled to increase to lower the temperature of the indoor unit heat exchanger.

[0119] When the execution time of the second drying program is greater than the drying time threshold, it can be considered that the condensed water in the air duct of the air conditioner has disappeared, and the drying of the air duct of the air conditioner can be stopped. Therefore, the execution of the second drying program can be controlled to stop.

[0120] In this embodiment, when the outdoor ambient temperature is low, the air duct of the air conditioner can be dried reliably and effectively by executing the second drying program, thereby ensuring the drying efficiency.

[0121] In yet another embodiment, the above-mentioned execution of the determined drying program further includes:

[0122] The target operating frequency is determined according to the acquired outdoor ambient temperature.

[0123] That is, the target operating frequency of the compressor is set to be related to the outdoor ambient temperature. When the outdoor ambient temperature is high, if the target operating frequency of the compressor is high, the operating state of the compressor may be unstable, and there is a risk of damage. The higher the outdoor ambient temperature, the lower the target operating frequency of the compressor; the lower the outdoor ambient temperature, the higher the target operating frequency of the compressor.

[0124] In this embodiment, a suitable target operating frequency is determined in real time according to the acquired outdoor ambient temperature to prevent the compressor from being damaged due to excessively high outdoor temperature.

[0125] In yet another embodiment, determining the target operating frequency according to the acquired outdoor ambient temperature includes:

[0126] A target operating frequency corresponding to the acquired outdoor ambient temperature is searched out in a predetermined first corresponding relationship as the determined target operating frequency, and the first corresponding relationship includes a corresponding relationship between the outdoor ambient temperature and the target operating frequency.

[0127] The first corresponding relationship between the outdoor ambient temperature and the target operating frequency can be preset by the designer. For example, when the outdoor ambient temperature is 25°C, the corresponding target operating frequency is determined to be 40Hz; when the outdoor ambient temperature is 30°C, the corresponding target operating frequency is determined to be 30Hz; when the outdoor ambient temperature is 35°C, the corresponding target operating frequency is determined to be 20Hz.

[0128] In this embodiment, a table lookup method is adopted to quickly determine the target operating frequency corresponding to the outdoor ambient temperature. The method is simple and the data processing speed is fast.

[0129] In yet another embodiment, the above-mentioned execution of the determined drying program further includes:

[0130] Determine the change value of the indoor air humidity content according to the difference between the indoor air humidity content at the time when the air conditioner is turned on during the current operation and the indoor air humidity content when the air conditioner receives the shutdown command;

[0131] The drying time threshold is determined according to the change value of the indoor air humidity content.

[0132] A sensor may be provided in the indoor unit of the air conditioner for obtaining the indoor air humidity of the air conditioner. For example, the sensor may be an air humidity sensor. The indoor air humidity at the time when the air conditioner is turned on and the indoor air humidity when the shutdown command is received may be obtained, and the indoor air humidity change value may be determined according to the difference between the indoor air humidity at the time when the air conditioner is turned on and the indoor air humidity when the shutdown command is received. For example, if the indoor air humidity at the time when the air conditioner is turned on is 50% and the indoor air humidity obtained when the shutdown command is received is 40%, the indoor air humidity change value may be determined to be 10%.

[0133] The greater the change value of the indoor air humidity content, the more the indoor air is dehumidified during the operation of the air conditioner, the greater the amount of moisture absorbed by the air, and the longer the drying time is required; the smaller the change value of the indoor air humidity content, the less the indoor air is dehumidified during the operation of the air conditioner, the smaller the amount of moisture absorbed by the air, and the shorter the time required to execute the drying program. Therefore, the drying time threshold can be determined according to the change value of the indoor air humidity content.

[0134] In this embodiment, the drying time threshold is determined according to the change value of the indoor air humidity content, so that the drying time can be flexibly controlled to make the drying time more suitable for the actual situation.

[0135] In yet another embodiment, the above-mentioned determination of the drying time threshold according to the change value of the indoor air humidity content includes:

[0136] The drying time threshold value corresponding to the determined change value of the indoor air humidity content is found in the predetermined second corresponding relationship as the determined drying time threshold value, and the second corresponding relationship includes the corresponding relationship between the change value of the indoor air humidity content and the drying time threshold value.

[0137] The second corresponding relationship between the change value of the indoor air humidity content and the drying time threshold value can be preset by the designer. The drying time threshold value can increase with the increase of the change value (or the interval of the change value) of the indoor air humidity content. For example, when the change value of the indoor air humidity content is 5%, the corresponding drying time threshold value is determined to be 10 minutes; when the change value of the indoor air humidity content is 10%, the corresponding drying time threshold value is determined to be 15 minutes; when the change value of the indoor air humidity content is 15%, the corresponding drying time threshold value is determined to be 20 minutes.

[0138] In this embodiment, a table lookup method is adopted to quickly determine the drying time threshold value corresponding to the change value of the indoor air humidity content. The method is simple and the data processing speed is fast.

[0139] In yet another embodiment, the above method further includes:

[0140] Get the dew point temperature of the indoor environment of the air conditioner;

[0141] If the air conditioner is in cooling mode or dehumidification mode during the current operation, upon receiving a shutdown command for instructing to shut down the air conditioner, determining a duration during the current operation that the temperature of the indoor unit heat exchanger is less than the obtained dew point temperature;

[0142] If the duration is greater than the second duration threshold, it is determined that the air duct of the air conditioner needs to be dried.

[0143] The indoor unit of the air conditioner may be provided with a temperature sensor and a humidity sensor, and the air dew point temperature is determined according to the air temperature detected by the temperature sensor and the air humidity detected by the humidity sensor. When the air conditioner is in cooling mode or dehumidification mode during this operation, if the temperature of the indoor unit heat exchanger drops below the air dew point temperature, the indoor unit evaporator of the air conditioner will generate condensed water, which will drip into the air duct of the air conditioner.

[0144] The shutdown command for instructing to turn off the air conditioner can be triggered and generated by the user through a mobile terminal. For example, the user can send a shutdown command by touching the "shutdown" button displayed on the screen of a mobile terminal (such as a mobile phone). Receiving a shutdown command for instructing to turn off the air conditioner, and the air conditioner is in cooling mode or dehumidification mode during this operation, it indicates that the user no longer needs to use the air conditioner, and condensed water may have accumulated in the air duct of the air conditioner. If the temperature of the indoor unit heat exchanger is lower than the dew point temperature for a duration greater than the second time threshold, it can be considered that there is a lot of condensed water in the air duct and the probability of natural drying is low, thereby determining that the air duct of the air conditioner needs to be dried.

[0145] When a shutdown command is received to instruct to shut down the air conditioner, and the air conditioner is in cooling mode or dehumidification mode during this operation, when the temperature of the indoor unit heat exchanger is lower than the determined dew point temperature for a period of time not greater than the second time threshold, it can be considered that there is less condensed water in the air duct of the air conditioner and it can be dried naturally, thereby determining that the air duct of the air conditioner does not need to be dried.

[0146] In this embodiment, when the air conditioner is in cooling mode or dehumidification mode during this operation, it can be accurately determined whether the air duct of the air conditioner needs to be dried according to the duration that the temperature of the indoor unit heat exchanger is lower than the determined dew point temperature. In addition, when a shutdown command is received to instruct to shut down the air conditioner, a judgment is made and drying is performed when necessary, which does not affect the user's use of the air conditioner and improves the user experience.
