[0052] In this embodiment, for ease of description, the following description uses an air conditioner as the subject of execution.

[0053] In the current technology, when the air conditioner is determined to have a risk of condensation based on detection data, the air conditioner will generally only operate at a reduced frequency, regardless of the level of risk. This will seriously weaken the cooling capacity of the air conditioner and affect indoor comfort.

[0054] This application provides the above solution, in which the compressor will no longer only operate at a reduced frequency during the anti-condensation control process of the air conditioner, but will operate at a higher frequency to reduce the weakening of cooling capacity, which can effectively improve the indoor cooling comfort during the anti-condensation process.

[0070] It should be understood that the various parts disclosed in this application can be implemented using hardware, software, firmware, or a combination thereof. In the description of the above embodiments, specific features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0071] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.

[0072] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or air conditioner capable of performing the above functions. The following description uses an air conditioner as an example to illustrate this embodiment and the subsequent embodiments.

[0073] Based on this, the embodiments of this application provide a control method for an air conditioner, referring to... Figure 4 , Figure 4 This is a flowchart illustrating the first embodiment of the control method for the air conditioner of this application.

[0074] In this embodiment, the control method of the air conditioner includes steps S10 to S30:

[0075] Step S10: If there is a risk of condensation in the air conditioner, control the compressor of the air conditioner to operate at a reduced frequency;

[0076] Whether an air conditioner has a risk of condensation can be determined by detecting the operating parameters during the air conditioner's operation, or by whether there is an instruction to activate the anti-condensation mode.

[0077] The compressor frequency reduction here can be based on pre-set frequency reduction parameters or on frequency reduction parameters determined by parameters that indicate the risk of condensation in the air conditioner.

[0078] In this embodiment, step S10 is executed during the operation of the air conditioner in a preset mode. In the preset mode, the first heat exchanger is in an evaporation state. The preset mode may include a cooling mode or a dehumidification mode.

[0079] Step S20: Obtain status parameters, which represent the degree of condensation risk of the air conditioner;

[0080] After the compressor operates at reduced frequency, status parameters are acquired at preset intervals.

[0081] Status parameters may include the air conditioner's own operating status parameters (such as indoor heat exchanger temperature) and / or the environmental status parameters of the indoor space where the air conditioner is located (such as indoor temperature and / or indoor humidity and / or indoor dew point temperature and / or indoor enthalpy).

[0082] Step S30: When the state parameters meet the preset conditions for low condensation risk, control the compressor of the air conditioner to operate at a higher frequency.

[0083] The term "low condensation risk" here refers to the fact that the air conditioner has a condensation risk, but the risk is relatively low. This is different from the statement that the air conditioner has no condensation risk.

[0084] Preset conditions may include the target range that the state parameters need to reach or the target relationship between the state parameters and preset parameters.

[0085] The frequency of an air conditioner can be increased according to a pre-set fixed frequency increase parameter, or it can be increased according to the frequency increase parameter determined by the actual operating status of the air conditioner.

[0086] This embodiment provides a control method for an air conditioner. When there is a risk of condensation in the air conditioner, the compressor is first controlled to operate at a reduced frequency. Then, when the risk of condensation is determined to be low by the status parameters, the air conditioner operates at a higher frequency. During the anti-condensation control process, the compressor will no longer only operate at a reduced frequency, but will operate at a higher frequency to reduce the weakening of cooling capacity, which can effectively improve the indoor cooling comfort during the anti-condensation process.

[0087] In one feasible implementation, the step of obtaining the state parameters includes: obtaining the indoor heat exchanger temperature of the air conditioner and the dew point temperature of the indoor space regulated by the air conditioner, wherein the state parameters include the indoor heat exchanger temperature and the dew point temperature.

[0088] The temperature of the indoor heat exchanger is specifically the temperature of the first heat exchanger mentioned above.

[0089] Dew point temperature can be detected by a dew point sensor or calculated by detecting indoor temperature and humidity.

[0090] Preset conditions may include a target relationship between indoor heat exchanger temperature and dew point temperature, or preset conditions may include a first target range for indoor heat exchanger temperature and a second target range for dew point temperature, etc.

[0091] In this embodiment, the preset condition includes the temperature difference between the indoor heat exchanger temperature and the dew point temperature being greater than or equal to a first preset temperature difference.

[0092] In this embodiment, the indoor heat exchanger temperature and dew point temperature can accurately reflect the current condensation risk level of the indoor space. Based on this, the cooling capacity can be increased as much as possible while ensuring the anti-condensation effect, so as to improve the indoor cooling comfort.

[0093] In one feasible implementation, the air conditioner includes at least two air outlets. Before the step of controlling the compressor of the air conditioner to operate at a higher frequency, the method further includes: when the state parameters meet the preset conditions for low condensation risk, obtaining the number and / or position of the currently open air outlets among the at least two air outlets; determining frequency adjustment parameters based on the number and / or position; the step of controlling the compressor of the air conditioner to operate at a higher frequency includes: controlling the compressor to operate at a higher frequency based on the frequency adjustment parameters.

[0094] Each air outlet can be turned on or off in response to user commands or monitored scene status data. For example, the first and second air outlets can both be turned on, while the third and fourth air outlets can both be turned off; or the first and third air outlets can both be turned on, while the second and fourth air outlets can both be turned off, and so on.

[0095] The frequency adjustment parameters will differ depending on the number and / or location of the air vents currently open on the air conditioner. Frequency adjustment parameters may include frequency adjustment amplitude or frequency adjustment ratio, etc.

[0096] In this embodiment, the frequency adjustment parameters are determined based on the quantity and location. One implementation involves different characteristic values ​​corresponding to different locations; the frequency adjustment parameters can be calculated by substituting the quantity and characteristic values ​​into a preset formula. Another implementation involves obtaining the correspondence between a numerical range and a preset frequency adjustment parameter based on the location; different locations correspond to different correspondences. The numerical range containing the quantity can be determined as the target range, and the preset frequency adjustment parameter corresponding to the target range can be used as the current frequency adjustment parameter for upsampling.

[0097] In this embodiment, the above method can ensure the anti-condensation effect of each air outlet and the cooling comfort of each air outlet area.

[0098] In one feasible embodiment, before the step of obtaining the state parameters of the air conditioner, the method further includes: obtaining the ambient temperature and ambient humidity; when the ambient temperature is within a preset temperature range and the ambient humidity is greater than a preset humidity, it is determined that the air conditioner has a risk of condensation.

[0099] In this embodiment, the preset temperature range is [21℃, 29℃].

[0100] In this embodiment, the above method can accurately identify whether an air conditioner has a risk of condensation.

[0101] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. In addition, after the step of obtaining the indoor heat exchanger temperature of the air conditioner and the dew point temperature of the indoor space regulated by the air conditioner, the method further includes:

[0102] When the temperature difference is less than the second preset temperature difference, the compressor is controlled to operate at a reduced frequency; and / or,

[0103] When the temperature difference is greater than or equal to the second preset temperature difference and less than the first preset temperature difference, the compressor is controlled to maintain the current frequency of operation.

[0104] Wherein, the second preset temperature difference is less than the first preset temperature difference.

[0105] The second preset temperature difference is specifically a critical value used to distinguish whether the risk of condensation on the air conditioner is severe. When the temperature difference is less than the second preset temperature difference, it indicates that the risk of condensation on the air conditioner is severe; when the temperature difference is between the first preset temperature difference and the second preset temperature difference, it indicates that the risk of condensation on the air conditioner is not severe.

[0106] After the compressor reduces its frequency or maintains its current frequency, it can return to the step of obtaining status parameters after a preset interval.

[0107] In this embodiment, when the risk of condensation is severe, the compressor operates at a reduced frequency to effectively reduce the risk of condensation; when the risk of condensation is not severe, the compressor maintains its current frequency to reduce the reduction in cooling capacity, thus achieving a balance between condensation prevention and cooling comfort.

[0108] In other embodiments, the compressor can also be controlled to operate at a reduced frequency when the temperature difference is less than a first preset temperature difference.

[0109] Based on any of the above embodiments, in the third embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. In this regard, the air conditioner includes at least two air outlets, each of which is provided with an air guide assembly, as described above. Figure 5 After step S10, the following steps are also included:

[0110] Step S01: When the air conditioner starts a preset mode, acquire detection status information, including whether there is a human body inside the air conditioner; wherein, in the preset mode, the indoor heat exchanger of the air conditioner is in an evaporation state.

[0111] In this embodiment, the detection status information includes whether the air conditioner is equipped with a human detection module. In this embodiment, the human detection module includes millimeter-wave radar. In other embodiments, the detection status information may also include whether the air conditioner receives data detected by other human detection modules located outside the air conditioner in the regulated indoor space, and may also include whether the human detection module connected to or installed in the air conditioner is malfunctioning.

[0112] Step S02: Control the operation of the air guide component according to the detection status information.

[0113] Air guide components can be used to adjust the air volume and / or air direction of the air outlet.

[0114] Based on the detected status information, the operation of all or some of the air guide components can be controlled. Different detected status information corresponds to different operating control parameters for the air guide components.

[0115] When the detection status information includes the absence of human detection information, the air guide component corresponding to the designated air outlet among the at least two air outlets is controlled to operate so that the airflow of the designated air outlet is greater than a preset airflow. In this embodiment, the air guide component corresponding to the designated air outlet can be controlled to deliver air at the maximum airflow angle so that the airflow reaches the maximum airflow. During this process, the air guide components corresponding to other air outlets besides the designated air outlet can maintain their current operation, for example, remain closed. Here, the designated air outlet is the air outlet determined according to user instructions.

[0116] When the detection status information includes the presence of the human body detection information, the system controls the air guide component corresponding to the designated air outlet among the at least two air outlets to maintain its current operation, and controls the air guide components corresponding to the air outlets other than the designated air outlet to operate away from the human body position corresponding to the human body detection information. The human body position can be determined based on the human body detection information. Maintaining the current operation can include keeping it closed. For example, if the human body position is on the left, the system controls the air guide component of the left air outlet to direct airflow to the right or close the air outlet, etc. The designated air outlet here is either an air outlet determined according to user instructions or an air outlet facing the human body position.

[0117] In this embodiment, the above method helps to ensure a large air volume during the start-up phase of the air conditioner to guarantee the heat exchange effect while preventing cold air from blowing into people.

[0118] In this embodiment, after the step of controlling the operation of the air guide component corresponding to the set air outlet among the at least two air outlets so that the air volume of the set air outlet is greater than the preset air volume, the method further includes: when there is a risk of condensation in the air conditioner, controlling the operation of the air guide component corresponding to the air outlet other than the set air outlet to increase the air volume.

[0119] Increasing the air volume here can include increasing the air volume when the air outlet is open or switching the air outlet from closed to open.

[0120] The air volume adjustment parameters for each air outlet can be preset fixed parameters or determined according to the actual operating status of the air conditioner. For example, the air volume adjustment parameters for each air outlet can be determined based on the current air volume, corresponding position and air direction of the air outlet other than the set air outlet, as well as condensation risk parameters (such as the temperature difference value and / or ambient temperature and / or dew point temperature, etc.).

[0121] In this embodiment, the risk of condensation in the air conditioner can be effectively reduced by using multiple air outlets.

[0122] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the control method of the air conditioner in this application.
