Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to an air conditioning control method, device, air conditioner, and storage medium. Background Technology

[0002] As people's living standards improve, the use of air conditioners has become increasingly widespread. During use, air conditioners mainly regulate the indoor temperature by exchanging heat through heat exchangers. These heat exchangers generally include indoor and outdoor heat exchangers. Since the outdoor heat exchanger is installed outdoors, its air inlet often attracts foreign objects or frost and other foreign objects may form on its surface due to the harsh outdoor environment. This affects the airflow of the heat exchanger and reduces its heat exchange performance. Summary of the Invention

[0003] This application provides an air conditioning control method, device, air conditioner, and storage medium, aiming to solve the problem that the heat exchanger's heat exchange performance is reduced due to foreign objects frequently adsorbing at the air inlet or frost forming on the surface of the heat exchanger caused by harsh outdoor environments, and to improve the heat exchanger's heat exchange performance.

[0004] In a first aspect, this application provides an air conditioning control method, the method comprising:

[0005] The foreign object detection device installed at the air inlet of the air conditioner detects the foreign object parameters in the current operating mode of the air conditioner.

[0006] Based on the relationship between the foreign object parameters and the corresponding preset parameters, the target operating parameters of the air conditioner in the working mode are determined.

[0007] The air conditioner is controlled to operate according to the target operating parameters.

[0008] In one possible implementation of this application, the foreign object parameter includes a foreign object distance value, and the preset parameter includes a preset distance value;

[0009] The step of determining the target operating parameters of the air conditioner in the operating mode based on the magnitude relationship between the foreign object parameters and the corresponding preset parameters includes:

[0010] If the air conditioner is in cooling mode and the size relationship is that the distance value of the foreign object is less than a preset distance value, then the first target number of the distance values ​​of the foreign objects that are less than the preset distance value is counted.

[0011] Based on the first target quantity, a first frequency for controlling the compressor of the air conditioner to reduce its frequency and a first rotational speed for controlling the fan of the air conditioner to reduce its speed are determined;

[0012] The first frequency and the first rotation speed are used as the target operating parameters of the air conditioner in the working mode.

[0015] In one possible implementation of this application, the foreign matter parameter includes the frost thickness value of the heat exchanger of the air conditioner, and the target operating parameter includes the air conditioner defrosting parameter;

[0016] The step of determining the target operating parameters of the air conditioner in the operating mode based on the magnitude relationship between the foreign object parameters and the corresponding preset parameters includes:

[0017] If the air conditioner is in heating mode, and the size relationship is that the frost thickness value of the heat exchanger is greater than the preset thickness value, then the second target number of frost thickness values ​​of the heat exchanger that are greater than the preset thickness value is counted, and the outdoor temperature and the pipe temperature of the refrigerant inlet pipe of the outdoor heat exchanger of the air conditioner are obtained.

[0018] Based on the second target quantity, the outdoor temperature, and the pipe temperature, determine the air conditioning defrosting parameters corresponding to the working mode for controlling air conditioning defrosting.

[0019] In one possible implementation of this application, determining the air conditioning defrosting parameters for controlling air conditioning defrosting based on the second target quantity, the outdoor temperature, and the pipe temperature includes:

[0020] If the second target quantity is greater than the preset target quantity threshold, and the outdoor temperature is less than the preset outdoor temperature threshold, and the pipe temperature is less than the preset pipe temperature threshold, then the preset defrosting control parameters corresponding to the air conditioner defrosting mode are obtained, and the defrosting control parameters are used as the air conditioner defrosting parameters.

[0021] In one possible implementation of this application, determining the air conditioning defrosting parameters for controlling air conditioning defrosting based on the second target quantity, the outdoor temperature, and the pipe temperature includes:

[0022] If the second target quantity is not greater than the preset target quantity threshold, and the outdoor temperature is not less than the preset outdoor temperature threshold, and the pipe temperature is not less than the preset pipe temperature threshold, then obtain the second frequency for controlling the compressor of the air conditioner to reduce its frequency and the second speed for controlling the fan of the air conditioner to reduce its speed.

[0024] In one possible implementation of this application, controlling the air conditioner operation according to the target operating parameters includes:

[0025] The compressor is controlled to operate at the second frequency, and the fan is controlled to operate at the second speed;

[0026] When the compressor's operating time reaches a first preset time, or the fan's operating time reaches a first operating time, the current frost thickness value of the heat exchanger is detected by the foreign object detection device.

[0027] If the frost thickness value of at least one of the current heat exchangers is greater than the preset thickness value, then the compressor is stopped for a second preset time and then started to run.

This solution, by installing a foreign object detection device at the air inlet and collecting foreign object parameters from the device in conjunction with the air conditioner's operating mode, determines the foreign object obstruction at the air inlet, thereby indirectly determining the airflow flow of the heat exchanger. This allows for the adjustment of the air conditioner's operating parameters, preventing foreign objects from adsorbing at the heat exchanger's air inlet or causing frost or other foreign objects to form on the heat exchanger surface due to harsh outdoor environments, thus affecting the airflow flow and improving the heat exchanger's heat exchange performance.

It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0052] This application provides an air conditioning control method, device, air conditioner, and storage medium, which will be described in detail below.

[0053] The air conditioning control method in this embodiment of the invention is applied to an air conditioning control device, which is installed in an air conditioner. The air conditioner has one or more processors, a memory, and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the processor to implement the air conditioning control method.

[0054] like Figure 1 As shown, Figure 1 This is a schematic diagram of a scenario for an air conditioning control method according to an embodiment of this application. The air conditioning control scenario in this embodiment includes an air conditioner 100 (which integrates an air conditioning control device). The air conditioner 100 runs a computer-readable storage medium (or simply storage medium) corresponding to the air conditioning control to execute the steps of the air conditioning control.

[0055] The air conditioner is equipped with at least one foreign object detection device at its air inlet for detecting foreign object parameters. The foreign object detection device may be an infrared detection device, a photosensitive detection device, or the like.

[0056] In this embodiment of the invention, the air conditioner 100 is mainly used for: detecting foreign object parameters in the current operating mode of the air conditioner through a foreign object detection device installed at the air inlet of the air conditioner; determining the target operating parameters of the air conditioner in the operating mode according to the relationship between the foreign object parameters and the corresponding preset parameters; and controlling the operation of the air conditioner according to the target operating parameters.

The air conditioner 100 can access the background database 300 (the background database can be in the local storage of the air conditioner, or it can be located in the cloud). The background database 300 stores information related to air conditioning control, such as air conditioning operating parameters and air conditioning identification.

[0059] It should be noted that, Figure 1 The schematic diagram of the air conditioning control method shown is merely an example. The scenarios of the air conditioning control method described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention and do not constitute a limitation on the technical solutions provided in the embodiments of the present invention.

[0060] like Figure 2 The diagram shown is a flowchart of an embodiment of the air conditioning control method in this application. The air conditioning control method includes steps S201-S203:

[0061] S201. A foreign object detection device installed at the air inlet of the air conditioner detects the foreign object parameters in the current operating mode of the air conditioner.

[0062] The air inlet of the air conditioner includes the indoor air inlet and / or the outdoor air inlet. It can be understood that the air inlet is generally set up to correspond to the heat exchanger.

[0063] The foreign object detection device is used to detect foreign object parameters at the air inlet. It can be an infrared rangefinder, an infrared thickness sensor, etc. It is understood that multiple foreign object detection devices can be set, such as one, three, or five. By setting the foreign object detection devices at different positions corresponding to the air inlet of the air conditioner, the foreign object parameters at the different positions can be detected.

[0064] It is understood that the foreign object detection device installed at the air inlet of the air conditioner can be installed on the heat exchanger and directly opposite the air inlet, or it can be installed on the side wall of the air inlet, or the foreign object detection device can be installed by setting a mounting bracket at the air inlet. This application does not make specific limitations.

[0065] The foreign object parameters, i.e., the foreign object parameters corresponding to the air inlet detected by the foreign object detection device, may include the foreign object distance value and / or the heat exchanger frost thickness value. It can be understood that the foreign object distance value is the distance between the foreign object and the foreign object detection device when the foreign object detection device detects the foreign object corresponding to the air inlet. It can be understood that if the foreign object detection device is located at the air inlet, then the foreign object distance value is equivalent to the distance of the foreign object to the air inlet; correspondingly, the heat exchanger frost thickness value.

[0066] The operating modes of an air conditioner include heating mode and cooling mode.

[0067] Specifically, when the air conditioner receives a work signal, it acquires the air conditioner's working mode and detects foreign object parameters in the current working mode using a foreign object detection device installed at the air inlet. It can be understood that the air conditioner can acquire foreign object parameters at a preset detection frequency, or after receiving a foreign object parameter detection command, or after detecting that the air conditioner has been working in the current working mode for a preset duration. Examples include:

[0068] In one embodiment of this application, when the current air conditioner is in heating mode, the foreign object distance value and the heat exchanger frost thickness value are detected and obtained by the foreign object detection device according to the preset foreign object parameter detection frequency.

[0069] In one embodiment of this application, when the current air conditioner is in heating mode, after the air conditioner is detected to have operated in heating mode for a preset duration, the frost thickness value of the heat exchanger is obtained by the foreign object detection device.

[0070] In one embodiment of this application, when the current air conditioner is in cooling mode, the distance value of the foreign object is detected and obtained by the foreign object detection device according to the preset foreign object parameter detection frequency.

[0071] S202. Based on the relationship between the foreign object parameter and the corresponding preset parameter, determine the target operating parameter of the air conditioner in the working mode.

[0072] The preset parameter thresholds include preset distance values ​​and / or preset thickness values. The relationship between the foreign object parameter and the corresponding preset parameter is, that is, the relationship between the foreign object distance value and the preset distance value or the relationship between the heat exchanger frost thickness value and the preset thickness value, or the relationship between the foreign object distance value and the preset distance value and the relationship between the heat exchanger frost thickness value and the preset thickness value.

[0073] The target operating parameters, i.e. the working parameters corresponding to the work done by the air conditioner, include the frequency of the compressor's work and the speed of the fan.

[0074] Specifically, after detecting foreign object parameters in the current operating mode of the air conditioner, the air conditioner determines the specific implementation method of the target operating parameters corresponding to the operating mode of the air conditioner based on the magnitude relationship between the foreign object parameters and the corresponding preset parameters. This application does not impose specific limitations on the specific implementation method, but provides an example:

[0075] In one embodiment of this application, when the air conditioner is in cooling mode, after detecting the distance value of a foreign object, the air conditioner compares the distance value of the foreign object with a preset distance value. If the distance value of the foreign object is greater than the preset distance value, it means that the foreign object does not affect the air intake of the air inlet, and the target operating parameter is the current air conditioner operating parameter. If the distance value of the foreign object is not greater than the preset distance value, the target operating parameter for reducing the air conditioner operating parameter is determined.

[0076] In another embodiment of this application, when the air conditioner is in heating mode, after detecting the distance value of the foreign object and the thickness of the frost on the heat exchanger, the distance value of the foreign object is compared with a preset distance value. If the distance value of the foreign object is greater than the preset distance value, it indicates that the foreign object does not affect the air intake of the air inlet, and the target operating parameter is the current operating parameter of the air conditioner. If the distance value of the foreign object is not greater than the preset distance value, the initial operating parameter for reducing the operating parameter of the air conditioner is determined. Further, the thickness of the frost on the heat exchanger is compared with a preset thickness value. If the thickness of the frost on the heat exchanger is greater than the preset thickness value, it indicates that the heat exchanger is frosted. Further, the initial operating parameter is further reduced and adjusted to obtain the target operating parameter. If the thickness of the frost on the heat exchanger is not greater than the preset distance value, it indicates that the heat exchanger is not frosted or the frost thickness does not affect the operation of the air conditioner, and the initial operating parameter can be determined as the target operating parameter.

[0077] S203. Control the operation of the air conditioner according to the target operating parameters.

[0078] Specifically, after determining the target operating parameters, the air conditioner controls its operation according to the target operating parameters. After the air conditioner has been running at the target operating parameters for a preset time, or after detecting no foreign objects based on the relationship between the newly acquired foreign object parameters and the corresponding preset parameters, the air conditioner is further controlled to restore the air conditioner operating parameters before adjustment.

[0079] In one embodiment of this application, the foreign object detection device is located on the heat exchanger directly opposite the air inlet. Multiple foreign object detection devices are provided at different positions on the heat exchanger. Each foreign object detection device detects a foreign object parameter. That is, when a foreign object parameter detection command is received from the air conditioner, all foreign object detection devices detect the corresponding foreign object parameter and feed the foreign object parameter back to the air conditioner. In other words, the air conditioner detects multiple foreign object parameters in the current operating mode of the air conditioner through the foreign object detection device located at the air inlet of the air conditioner.

[0080] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 3 , Figure 3 A schematic diagram of one implementation scheme for determining the target operating parameters in the air conditioning control method provided in this application, including steps S301-S303:

[0081] S301. If the air conditioner is in cooling mode and the size relationship is that the distance value of the foreign object is less than a preset distance value, then count the first target number of the distance values ​​of the foreign objects that are less than the preset distance value.

[0082] The first target number is the number of foreign object distance values ​​that are less than the preset distance value among all foreign object distance values.

[0083] Specifically, when the air conditioner is operating in cooling mode, a foreign object detection device installed at the air inlet detects multiple foreign object distance values ​​in the current operating mode. Each foreign object distance value is compared to a preset distance value, where the comparison indicates either the foreign object distance value is greater than the preset distance value, or the foreign object distance value is not greater than the preset distance value. That is, if all comparisons show the foreign object distance value is greater than the preset distance value, it indicates there are no foreign objects or the foreign objects do not affect airflow from the air inlet, and the target operating parameter is the current air conditioner operating parameter. If any foreign object distance value is not greater than the preset distance value, a first target number of foreign object distance values ​​less than the preset distance value is counted.

[0084] S302. Based on the first target quantity, determine a first frequency for controlling the compressor of the air conditioner to reduce its frequency and a first rotational speed for controlling the fan of the air conditioner to reduce its speed.

[0085] Specifically, after determining the first target quantity, the air conditioner uses a first frequency and a first rotation speed based on the first target quantity. This application does not specify a particular method for implementing these parameters, but an example is provided:

[0086] In some embodiments of this application, the air conditioner compares a first target quantity with a preset quantity threshold. If the first target quantity is greater than the preset quantity threshold, a first preset frequency is determined as the first frequency and a first preset rotation speed is determined as the first rotation speed. If the first target quantity is not greater than the preset quantity threshold, a second preset frequency is determined as the first frequency and a second preset rotation speed is determined as the first rotation speed. The first preset frequency is less than the second preset frequency and the first preset rotation speed is less than the second preset rotation speed.

[0087] In some other embodiments of this application, after obtaining the first target quantity, the air conditioner searches a preset mapping table corresponding to the quantity and operating parameters to obtain the target operating parameters corresponding to the first target quantity.

[0088] S303. The first frequency and the first speed are used as the target operating parameters of the air conditioner in the working mode.

[0089] Specifically, after obtaining the first frequency and the first speed, the air conditioner uses the first frequency and the first speed as the target operating parameters corresponding to the air conditioner in the working mode to control the operation of the air conditioner.

[0090] In this implementation scheme, by setting up multiple foreign object detection devices to detect the distance values ​​of foreign objects at different locations, it is possible to detect foreign object parameters at different locations. That is, while detecting foreign objects, the size of the coverage area of ​​the foreign objects is also detected. Based on the number of the first target, i.e. the size of the foreign object coverage area, different target operating parameters are determined, thereby improving the accuracy of the target operating parameters and making the air conditioning control more reasonable.

[0091] Specifically, in one embodiment of this application, determining the first frequency for controlling the compressor of the air conditioner to reduce its frequency and the first rotational speed for controlling the fan of the air conditioner to reduce its speed based on the first target quantity specifically includes: if the first target quantity is equal to the total number of foreign object distance values, then obtaining the lowest operating frequency of the compressor and determining the lowest operating frequency as the first frequency, and determining the first rotational speed as zero. That is, it can be understood that if the first target quantity is equal to the total number of foreign object distance values, that is, all foreign object distance values ​​are less than a preset distance value, it indicates that there are foreign objects and the attachment area of ​​the foreign objects on the heat exchanger surface is large, which will affect the work of the air conditioner. In this case, the compressor is controlled to operate at the lowest operating frequency, and the fan is controlled to stop, so that the attached foreign objects fall off.

[0092] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 4 , Figure 4 A schematic diagram of another implementation scheme for determining the target operating parameters in the air conditioning control method provided in this application, including steps S401-S402:

[0093] S401. If the air conditioner's operating mode is heating mode, and the magnitude relationship is that the frost thickness value of the heat exchanger is greater than the preset thickness value, then count the second target number of frost thickness values ​​of the heat exchanger that are greater than the preset thickness value, and obtain the outdoor temperature and the pipe temperature of the refrigerant inlet pipe of the outdoor heat exchanger of the air conditioner.

[0094] The second target number is the number of heat exchangers with frost thickness values ​​that are less than the preset thickness value among all heat exchanger frost thickness values.

[0095] Wherein, the outdoor ambient temperature is the ambient temperature corresponding to the heat exchanger used as the evaporator in the air conditioner. In heating mode, the outdoor heat exchanger, which is generally installed outdoors, is used as the evaporator. That is, the outdoor temperature is the outdoor ambient temperature.

[0096] The temperature of the refrigerant inlet pipe of the outdoor heat exchanger is the pipe temperature of the corresponding pipe through which the low-temperature refrigerant flows into the outdoor heat exchanger.

[0097] Specifically, when the air conditioner is operating in heating mode, a foreign object detection device installed at the air inlet detects the frost thickness values ​​of multiple heat exchangers in the current operating mode. Each heat exchanger frost thickness value is compared to a preset thickness value, where the frost thickness value is greater than the preset thickness value, or the frost thickness value is not greater than the preset thickness value. That is, if all comparisons show that the frost thickness value is greater than the preset thickness value, it indicates that there is no frost or foreign object buildup on the heat exchanger surface, or the thickness of the foreign object does not affect heat exchange. The target operating parameter is the current air conditioner operating parameter. If any heat exchanger frost thickness value is greater than the preset thickness value, a second target number of frost thickness values ​​greater than the preset thickness value is counted, and the outdoor temperature and pipe temperature are obtained.

[0098] It is understood that the outdoor temperature and pipe temperature can be obtained through a dimension sensor that communicates with the air conditioner.

[0099] S402. Based on the second target quantity, the outdoor temperature, and the pipe temperature, determine the air conditioning defrosting parameters corresponding to the working mode for controlling the air conditioning defrosting.

[0100] Specifically, in some embodiments of this application, after obtaining the second target quantity, outdoor temperature and pipe temperature, the air conditioner can obtain the air conditioner defrosting parameters corresponding to the second target quantity, outdoor temperature and pipe temperature by looking up a preset mapping table.

[0101] Specifically, in some other embodiments of this application, after obtaining the second target quantity, the outdoor temperature, and the pipe temperature, the air conditioner compares the second target quantity with a preset quantity threshold, compares the outdoor temperature with a preset outdoor temperature threshold, and compares the pipe temperature with a preset pipe temperature threshold. If the second target quantity is greater than the preset target quantity threshold, and the outdoor temperature is less than the preset outdoor temperature threshold, and the pipe temperature is less than the preset pipe temperature threshold, then the preset defrosting control parameters corresponding to the air conditioner defrosting mode are obtained, and the defrosting control parameters are used as the air conditioner defrosting parameters. It is understandable that when the second target quantity is greater than the preset target quantity threshold, it indicates that the frost layer on the heat exchanger covers a large area. At the same time, the outdoor temperature is lower than the preset outdoor temperature threshold, indicating that the outdoor temperature is low, and the pipe temperature is lower than the preset pipe temperature threshold, indicating that the refrigerant temperature is low. These conditions will cause the heat exchanger to frost, and the degree of frost is relatively severe. At this time, the preset defrosting control parameters corresponding to the defrosting mode of the air conditioner are directly obtained, and the defrosting control parameters are used as the defrosting parameters of the air conditioner. The air conditioner is controlled to temporarily enter the defrosting mode according to the defrosting parameters. It is understood that the activation of the defrosting mode is a sub-mode in the air conditioner's heating mode. That is, after the air conditioner runs in the defrosting mode with the defrosting parameters for a preset duration, it will resume the air conditioner's heating mode.

[0102] Furthermore, in some embodiments of this application, after obtaining the second target quantity, outdoor temperature, and pipe temperature, the air conditioner compares the second target quantity with a preset quantity threshold, the outdoor temperature with a preset outdoor temperature threshold, and the pipe temperature with a preset pipe temperature threshold. If the second target quantity is not greater than the preset target quantity threshold, and the outdoor temperature is not less than the preset outdoor temperature threshold, and the pipe temperature is not less than the preset pipe temperature threshold, then a second frequency for controlling the compressor frequency reduction of the air conditioner and a second speed for controlling the fan speed reduction of the air conditioner are obtained. The second frequency and the second speed are used as the target operating parameters of the air conditioner corresponding to the operating mode. It can be understood that when the second target quantity is not greater than the preset target quantity threshold, it indicates that the frost layer covering the heat exchanger is small. At the same time, the outdoor temperature not being less than the preset outdoor temperature threshold indicates that the outdoor temperature is not low, and the pipe temperature not being less than the preset pipe temperature threshold indicates that the refrigerant temperature is not low. These conditions will cause the frost layer to melt slowly after the air conditioner reduces the preset frequency and fan speed, without needing to activate the defrosting mode.

[0103] Furthermore, in some other embodiments of this application, after obtaining the second target quantity, the outdoor temperature, and the pipe temperature, the air conditioner compares the second target quantity with a preset quantity threshold, compares the outdoor temperature with a preset outdoor temperature threshold, and compares the pipe temperature with a preset pipe temperature threshold. If the second target quantity is greater than the preset target quantity threshold, and the outdoor temperature is not less than the preset outdoor temperature threshold, and the pipe temperature is not less than the preset pipe temperature threshold, then the minimum operating frequency of the air conditioner is obtained, and the minimum operating frequency is determined as the second frequency, and the second rotation speed is zero.

[0104] It is understood that this application does not impose specific limitations on the specific implementation method of determining the air conditioning defrosting parameters for controlling air conditioning defrosting based on the second target quantity, outdoor temperature, and the pipe temperature, and the design can be carried out according to actual needs.

[0105] Furthermore, based on the above implementation plan, see [link to relevant documentation].

[0106] S501. A foreign object detection device installed at the air inlet of the air conditioner detects foreign object parameters in the current operating mode of the air conditioner.

[0107] S502. If the air conditioner's operating mode is heating mode, then compare the magnitude relationship between the foreign object parameter and the corresponding preset parameter.

[0108] S503. If the size relationship is that the frost thickness value of the heat exchanger is greater than the preset thickness value, then count the second target number of frost thickness values ​​of the heat exchanger that are greater than the preset thickness value, and obtain the outdoor temperature and the pipe temperature of the refrigerant inlet pipe of the outdoor heat exchanger of the air conditioner.

[0109] S504. If the second target quantity is not greater than a preset target quantity threshold, and the outdoor temperature is not less than a preset outdoor temperature threshold, and the pipe temperature is not less than a preset pipe temperature threshold, then obtain a second frequency for controlling the compressor of the air conditioner to reduce its frequency and a second rotation speed for controlling the fan of the air conditioner to reduce its speed.

[0110] S505. The second frequency and the second speed are used as the target operating parameters of the air conditioner in the working mode.

[0111] The specific implementation methods of steps S501-505 are shown in any of the above implementation schemes.

[0112] S506. Control the compressor to operate at the second frequency and control the fan to operate at the second speed.

[0113] Specifically, after obtaining the first frequency and second speed corresponding to the heating mode, the air conditioner controls the compressor to reduce its operating frequency to the second frequency and controls the outdoor fan corresponding to the outdoor heat exchanger to reduce its speed to the second speed.

[0114] S507. When the running time of the compressor reaches a first preset time, or the running time of the fan reaches a first running time, the current frost thickness value of the heat exchanger is detected by the foreign object detection device.

[0115] Furthermore, the air conditioner controls the compressor to reduce its operating frequency to a second frequency, and controls the outdoor fan corresponding to the outdoor heat exchanger to reduce its speed to the second speed. After running at the second speed, the air conditioner obtains the running time of the fan running at the second speed and the running time of the compressor running at the second frequency. When the running time of the compressor is detected to reach a first preset time, or the running time of the fan is detected to reach the first running time, the air conditioner obtains the current frost thickness value of the heat exchanger detected by the foreign object detection device.

[0116] S508. If the frost thickness value of at least one of the current heat exchangers is greater than the preset thickness value, then the compressor is started after being stopped for a second preset time.

[0117] Furthermore, after obtaining the current frost thickness value of the heat exchanger, the air conditioner compares the current frost thickness value with a preset thickness value according to the size comparison method described in any of the above embodiments. If at least one of the current frost thickness values ​​of the heat exchanger is greater than the preset thickness value, the compressor is stopped for a second preset time and then started. It can be understood that if at least one of the current frost thickness values ​​of the heat exchanger is greater than the preset thickness value, it means that there is still frost, indicating that the adjustment method of running the compressor at the second frequency and the fan at the second speed cannot defrost. Therefore, the compressor is stopped to increase the defrosting rate. Furthermore, after the compressor is stopped for a preset time, the compressor operation mode of starting the compressor can be controlling the compressor to run at the frequency before frequency reduction or controlling the compressor to run at the second frequency. This application does not make specific limitations on the specific operation mode.

[0118] This application provides an air conditioning control method. A foreign object detection device installed at the air inlet of the air conditioner detects foreign object parameters in the current operating mode of the air conditioner. Based on the relationship between the foreign object parameters and corresponding preset parameters, a target operating parameter for the air conditioner in the operating mode is determined. The air conditioner is then controlled to operate according to the target operating parameter. This solution, by installing a foreign object detection device at the air inlet of the air conditioner and combining this with the foreign object parameters collected by the device during the air conditioner's operating mode, determines the extent of foreign object obstruction at the air inlet, thereby indirectly determining the airflow flow of the heat exchanger. This allows for the adjustment of the air conditioner's operating parameters accordingly, preventing foreign objects from adsorbing at the air inlet of the heat exchanger or causing frost or other foreign objects to form on the surface of the heat exchanger due to harsh outdoor environments, thus affecting the airflow flow and improving the heat exchanger's heat exchange performance.

[0128] If the first target quantity is equal to the total number of foreign object distance values, then the lowest operating frequency of the compressor is obtained, and the lowest operating frequency is determined as the first frequency, and the first rotation speed is determined to be zero.

[0129] In one possible implementation of this application, the foreign object parameter includes the frost thickness value of the air conditioner's heat exchanger, and the target operating parameter includes the air conditioner's defrosting parameter; the parameter determination module 602 is used to determine the target operating parameter of the air conditioner in the operating mode based on the magnitude relationship between the foreign object parameter and the corresponding preset parameter, specifically including:

[0130] If the air conditioner is in heating mode, and the size relationship is that the frost thickness value of the heat exchanger is greater than the preset thickness value, then the second target number of frost thickness values ​​of the heat exchanger that are greater than the preset thickness value is counted, and the outdoor temperature and the pipe temperature of the refrigerant inlet pipe of the outdoor heat exchanger of the air conditioner are obtained.

[0131] Based on the second target quantity, the outdoor temperature, and the pipe temperature, determine the air conditioning defrosting parameters corresponding to the working mode for controlling air conditioning defrosting.

[0132] In one possible implementation of this application, the parameter determination module 602 is used to determine air conditioning defrosting parameters for controlling air conditioning defrosting based on the second target quantity, the outdoor temperature, and the pipe temperature, specifically including:

[0133] If the second target quantity is greater than the preset target quantity threshold, and the outdoor temperature is less than the preset outdoor temperature threshold, and the pipe temperature is less than the preset pipe temperature threshold, then the preset defrosting control parameters corresponding to the air conditioner defrosting mode are obtained, and the defrosting control parameters are used as the air conditioner defrosting parameters.

[0134] In one possible implementation of this application, the parameter determination module 602 is used to determine air conditioning defrosting parameters for controlling air conditioning defrosting based on the second target quantity, the outdoor temperature, and the pipe temperature, specifically including:

[0135] If the second target quantity is not greater than the preset target quantity threshold, and the outdoor temperature is not less than the preset outdoor temperature threshold, and the pipe temperature is not less than the preset pipe temperature threshold, then obtain the second frequency for controlling the compressor of the air conditioner to reduce its frequency and the second speed for controlling the fan of the air conditioner to reduce its speed.

[0136] The second frequency and the second rotation speed are used as the target operating parameters of the air conditioner in the working mode.

[0137] In one possible implementation of this application, the control module 603 is used to control the operation of the air conditioner according to the target operating parameters, specifically including:

[0138] The compressor is controlled to operate at the second frequency, and the fan is controlled to operate at the second speed;

[0139] When the compressor's operating time reaches a first preset time, or the fan's operating time reaches a first operating time, the current frost thickness value of the heat exchanger is detected by the foreign object detection device.

[0140] If the frost thickness value of at least one of the current heat exchangers is greater than the preset thickness value, then the compressor is stopped for a second preset time and then started to run.
