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.
[0049] Currently, with the rapid development of air conditioners, more and more users are using air conditioners for temperature regulation. Existing air conditioner outdoor units, after entering closed-loop control, adjust fan speed based on system load. However, because outdoor units may face different environmental operating conditions, such as blocked or obstructed fan shrouds, or unstable fan current, the system load-based fan speed adjustment cannot fully cover all operating conditions, leading to a decrease in air conditioner performance.
[0050] Based on this, this application proposes an air conditioning control method, device, equipment, and computer-readable storage medium to solve the technical problem in the prior art that the speed regulation of the outdoor fan of an air conditioner cannot cover all operating conditions, resulting in poor performance of the air conditioner.
[0051] 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 is provided with one or more processors, a memory, and one or more application programs. 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. The air conditioner can be various types of air conditioners such as portable air conditioners, window air conditioners, wall-mounted air conditioners, and floor-standing air conditioners.
[0052] 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 the present application. The air conditioning control scenario in this embodiment includes an air conditioner 100 (the air conditioner 100 integrates an air conditioning control device), and the air conditioner 100 has a computer-readable storage medium corresponding to the air conditioning control method running in it to execute the steps of the air conditioning control method.
[0053] Understandable, Figure 1The air conditioner in the air conditioning control method scenario shown, or the device contained in the air conditioner, does not constitute a limitation on the embodiments of the present invention. That is, the number or type of air conditioner in the air conditioning control method scenario, or the number or type of device contained in each device, does not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.
[0054] In this embodiment of the invention, the air conditioner 100 is mainly used to: respond to an air conditioning control request for the air conditioner, obtain the wind pressure difference detection value of the air conditioner, and the current outdoor fan speed of the air conditioner;
[0055] The speed of the outdoor fan in the air conditioner is adjusted according to the wind pressure difference detection value, the wind pressure difference setting value of the current outdoor fan speed and the preset wind pressure difference control value to obtain the target outdoor fan speed of the current outdoor fan speed.
[0056] The current outdoor fan speed of the air conditioner is adjusted according to the fan phase current corresponding to the target outdoor fan speed and the preset speed reduction current to obtain the target outdoor fan speed, and the air conditioner is controlled to adjust the air conditioning operation status according to the target outdoor fan speed.
[0057] In this embodiment of the invention, the air conditioner 100 can be an independent air conditioner, such as a portable air conditioner, a window air conditioner, a wall-mounted air conditioner, and a cabinet air conditioner, or it can be an air conditioning control network or an air conditioning control cluster composed of multiple air conditioners.
[0058] This application provides an air conditioning control method, apparatus, device, and computer-readable storage medium, which will be described in detail below.
[0059] It will be understood by those skilled in the art that Figure 1 The application environment shown is only one application scenario related to the solution of this application and does not constitute a limitation on the application scenario of this application. Other application environments may include more than one application scenario. Figure 1 The number of more or fewer air conditioners shown, or the air conditioning control network connections, for example Figure 1 Only one air conditioner is shown in the diagram. It is understood that the scenario of the air conditioning control method may also include one or more air conditioners, which is not limited here. The air conditioner 100 may also include a memory for storing wind pressure difference detection data and other data.
[0060] 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.
[0061] Based on the above-mentioned air conditioner control method, various embodiments of the disclosed air conditioner control method are proposed.
[0062] As Figure 2 shown, Figure 2 is a flowchart of an embodiment of the air conditioner control method in the present application. The air conditioner control method comprises the following steps 201-203:
[0063] 201. In response to an air conditioner control request for an air conditioner, an air pressure difference detection value of the air conditioner and a current outdoor fan gear of the air conditioner are obtained.
[0064] The air conditioner control method in the embodiment is applied to an air conditioner, and the type and number of the air conditioner are not specifically limited, i.e., the air conditioner can be one or more mobile air conditioners, air conditioner window units, air conditioner hanging units, air conditioner cabinet units, and various types of air conditioners. Optionally, the air conditioner can also be at least one air conditioner extension in a distributed air conditioning system. In a specific embodiment, the air conditioner is an air conditioner hanging unit.
[0065] Specifically, to avoid the situation that the existing air conditioner cannot cover all operating conditions when adjusting the speed of the outdoor fan of the air conditioner according to the system load, the air conditioner is configured to adjust the outdoor fan gear and the outdoor fan speed of the air conditioner according to the air pressure difference detection value and the fan phase current of the outdoor fan of the air conditioner, thereby improving the operating performance of the air conditioner.
[0066] Specifically, the air conditioner is operated in response to an air conditioner control request for the air conditioner, wherein the air conditioner control request is an operation event for driving the air conditioner to adjust the outdoor fan speed of the air conditioner control device. Optionally, the triggering method of the air conditioner control request is not specifically limited here, i.e., the air conditioner control request can be actively triggered by the user, for example, the user actively triggers the air conditioner control request by clicking the air conditioner control button on the control panel of the air conditioner or the remote controller in communication connection with the air conditioner. Optionally, in other embodiments, the air conditioner control request can also be actively triggered by the air conditioner, for example, a speed adjustment process is set in the air conditioner, and the air conditioner actively triggers the air conditioner control request when the outdoor operating condition of the air conditioner meets a specific condition.
[0067] Specifically, after receiving the air conditioner control request, the air conditioner obtains the air pressure difference detection value of the air conditioner and reads the current outdoor fan gear of the outdoor fan of the air conditioner. The air pressure difference detection value is a parameter representing the air pressure difference between the air outlet and the air return of the air conditioner. The air pressure difference detection value affects the air conditioning operating state of the air conditioner. If the air pressure difference detection value is small, the air supply of the air conditioner will be insufficient, and the temperature control effect will be poor. If the air pressure difference detection value is large, the noise of the air conditioner will be too large, and the energy consumption will increase.
[0068] The outer fan gear of the air conditioner is a different preset wind gear position representing the difference in the rotation speed of the outer fan of the air conditioner. In a specific embodiment, the outer fan gear of the air conditioner is set to a silent gear position, a low wind gear position, a medium wind gear position, a high wind gear position, and an ultra-high wind gear position according to actual temperature control requirements.
[0069] Specifically, the air conditioner is pre-installed with a wind pressure difference sensor on the outer fan shroud of the air conditioner. After receiving an air conditioner control request, the wind pressure difference sensor collects the wind pressure difference detection value of the outer fan of the air conditioner. That is, the wind pressure difference sensor installed on the outer fan shroud of the air conditioner can detect the wind pressure difference between the air supply port and the return air port of the outer fan of the air conditioner, and convert it into an electrical signal output to the processing module of the air conditioner. The processing module of the air conditioner obtains the wind pressure difference detection value of the air conditioner by analyzing the electrical signal. Optionally, in a specific embodiment, the wind pressure difference sensor includes a sensitive element, a signal amplifier, and a signal processing circuit. The sensitive element can be a micro pressure sensor or a load sensor, which can quickly and accurately detect the change in the wind pressure difference. The signal amplifier and the processing circuit amplify, filter, linearize, and process the wind pressure difference signal, convert the electrical signal output by the sensor into a standard signal, and obtain the wind pressure difference detection value.
[0070] 202. Adjust the rotation speed of the outer fan in the air conditioner according to the wind pressure difference detection value, the wind pressure difference set value of the current outer fan gear, and the preset wind pressure difference control value, to obtain the target rotation speed of the outer fan in the current outer fan gear of the air conditioner;
[0071] Specifically, after obtaining the wind pressure difference detection value of the outer fan of the air conditioner, the air conditioner also adjusts the rotation speed of the outer fan in the air conditioner according to the wind pressure difference detection value, the wind pressure difference set value of the current outer fan gear, and the preset wind pressure difference control value, to obtain the target rotation speed of the outer fan in the current outer fan gear of the air conditioner. The target rotation speed of the outer fan is the rotation speed of the outer fan obtained by adjusting the rotation speed of the outer fan in the current outer fan gear of the air conditioner according to the wind pressure difference detection value.
[0072] Specifically, before adjusting the rotation speed of the outer fan of the air conditioner, the air conditioner also pre-sets the wind pressure difference set value corresponding to different outer fan gears of the outer fan of the air conditioner, and stores the wind pressure difference set value and the corresponding outer fan gear in the preset database.
[0073] Specifically, after obtaining the wind pressure difference detection value of the outer fan of the air conditioner and the current outer fan gear of the air conditioner, the air conditioner also accesses the preset database, inputs the flag corresponding to the current outer fan gear into the preset database, and queries the wind pressure difference set value corresponding to the current outer fan gear in the preset database.
[0074] For example, in one specific example, if the current outdoor fan gear of the air conditioner is a silent outdoor fan gear, the air conditioner accesses the preset database to determine that the wind pressure difference set value corresponding to the silent outdoor fan gear is a silent wind pressure difference value.
[0075] For example, in another specific example, if the current outdoor fan gear of the air conditioner is a low wind outdoor fan gear, the air conditioner accesses the preset database to determine that the wind pressure difference set value corresponding to the low wind outdoor fan gear is a low wind wind pressure difference value.
[0076] For example, in another specific example, if the current outdoor fan gear of the air conditioner is a medium wind outdoor fan gear, the air conditioner accesses the preset database to determine that the wind pressure difference set value corresponding to the medium wind outdoor fan gear is a medium wind wind pressure difference value.
[0077] For example, in another specific example, if the current outdoor fan gear of the air conditioner is a high wind outdoor fan gear, the air conditioner accesses the preset database to determine that the wind pressure difference set value corresponding to the high wind outdoor fan gear is a high wind wind pressure difference value.
[0078] For example, in another specific example, if the current outdoor fan gear of the air conditioner is an ultra-high wind outdoor fan gear, the air conditioner accesses the preset database to determine that the wind pressure difference set value corresponding to the ultra-high wind outdoor fan gear is an ultra-high wind wind pressure difference value.
[0079] Specifically, after obtaining the wind pressure difference set value of the current outdoor fan gear, the air conditioner calculates a wind pressure difference control threshold value corresponding to the current outdoor fan gear of the air conditioner according to the wind pressure difference set value and a preset wind pressure difference control value, wherein the wind pressure difference control threshold value is a judgment threshold value for judging whether the outdoor fan speed of the outdoor fan of the air conditioner needs to be adjusted. The operation instruction for adjusting the outdoor fan speed of the outdoor fan of the air conditioner is determined by comparing the wind pressure difference detection value and the wind pressure difference control threshold value, and the outdoor fan speed of the current outdoor fan gear of the outdoor fan is adjusted based on the operation instruction to obtain a target outdoor fan speed.
[0080] Optionally, in one embodiment, the wind pressure difference control threshold value includes a first wind pressure difference control threshold value and a second wind pressure difference control threshold value, wherein the first wind pressure difference control threshold value is a control threshold value indicating that the outdoor fan speed of the current outdoor fan gear needs to be reduced, and the second wind pressure difference control threshold value is a control threshold value indicating that the outdoor fan speed of the current outdoor fan gear needs to be increased.
[0081] Specifically, after obtaining the wind pressure difference set value, the air conditioner calculates the sum of the wind pressure difference set value and the preset wind pressure difference control value, and sets the sum of the wind pressure difference set value and the preset wind pressure difference control value as the first wind pressure difference control threshold value.
[0082] Specifically, the air conditioner calculates the difference between the wind pressure difference set value and the preset wind pressure difference control value after obtaining the wind pressure difference set value, and sets the difference between the wind pressure difference set value and the preset wind pressure difference control value as the second wind pressure difference control threshold value.
[0083] Specifically, the air conditioner compares the first wind pressure difference control threshold value, the second wind pressure difference control threshold value and the wind pressure difference detection value after obtaining the first wind pressure difference control threshold value and the second wind pressure difference control threshold value, and adjusts the current outdoor fan speed of the outdoor fan of the air conditioner according to the comparison result to obtain a target outdoor fan speed.
[0084] Optionally, if the wind pressure difference detection value of the air conditioner is greater than the first wind pressure difference control threshold value, that is, the wind pressure difference detection value of the air conditioner is greater than the sum of the wind pressure difference set value and the preset wind pressure difference control value of the current outdoor fan speed, the air conditioner determines that the outdoor fan speed of the current outdoor fan speed of the outdoor fan of the air conditioner needs to be reduced. The air conditioner reduces the outdoor fan speed of the current outdoor fan speed of the outdoor fan of the air conditioner according to the preset speed adjustment interval and the speed adjustment parameter. In one specific embodiment, the preset speed adjustment interval is 60s (unit: second), and the speed adjustment parameter is 1%. That is, after the air conditioner determines that the outdoor fan speed of the current outdoor fan speed of the outdoor fan of the air conditioner needs to be reduced, the outdoor fan speed is reduced by 1% every 60s on the basis of the basic wind speed of the current outdoor fan speed until the wind pressure difference detection value is less than the first wind pressure difference control threshold value and greater than the second wind pressure difference control threshold value or the outdoor fan speed is reduced to the preset minimum outdoor fan speed of the outdoor fan of the air conditioner.
[0085] Optionally, if the wind pressure difference detection value of the air conditioner is less than the second wind pressure difference control threshold value, that is, the wind pressure difference detection value of the air conditioner is less than the difference between the wind pressure difference set value and the preset wind pressure difference control value of the current outdoor fan speed, the air conditioner determines that the outdoor fan speed of the current outdoor fan speed of the outdoor fan of the air conditioner needs to be increased. The air conditioner reduces the outdoor fan speed of the current outdoor fan speed of the outdoor fan of the air conditioner according to the preset speed adjustment interval and the speed adjustment parameter. That is, after the air conditioner determines that the outdoor fan speed of the current outdoor fan speed of the outdoor fan of the air conditioner needs to be increased, the outdoor fan speed is increased by 1% every 60s on the basis of the basic wind speed of the current outdoor fan speed until the wind pressure difference detection value is less than the first wind pressure difference control threshold value and greater than the second wind pressure difference control threshold value or the outdoor fan speed is increased to the preset maximum outdoor fan speed of the outdoor fan of the air conditioner.
[0086] Optionally, if the wind pressure difference detection value of the air conditioner is less than the first wind pressure difference control threshold value and greater than the second wind pressure difference control threshold value, the air conditioner determines that the operating condition of the outdoor fan is normal (that is, the outdoor fan cover does not appear the blocking condition), and does not adjust the speed of the current outdoor fan speed of the outdoor fan.
[0087] Optionally, in other embodiments, the air conditioner can also determine whether the wind pressure difference sensor is faulty according to the wind pressure difference detection value, thereby improving the effectiveness of the current outdoor fan gear adjustment.
[0088] 203、adjust the current outdoor fan gear of the air conditioner according to the fan phase current corresponding to the target outdoor fan rotating speed and the preset rotating speed reduction current, to obtain a target outdoor fan gear, and control the air conditioner to adjust the air conditioner operating state of the air conditioner according to the target outdoor fan gear.
[0089] Specifically, after the air conditioner adjusts the current outdoor fan gear according to the wind pressure difference detection value to obtain a target outdoor fan rotating speed, the air conditioner further adjusts the current outdoor fan gear of the air conditioner according to the fan phase current of the air conditioner and the preset rotating speed reduction current corresponding to the target outdoor fan rotating speed, to obtain a target outdoor fan gear, and controls the air conditioner to adjust the air conditioner operating state of the air conditioner according to the target outdoor fan gear.
[0090] Specifically, the air conditioner obtains the fan phase current corresponding to the target outdoor fan rotating speed of the outdoor fan, and the preset rotating speed reduction current of the outdoor fan of the air conditioner. The fan phase current is the three-phase alternating current of the outdoor fan motor in the air conditioner. The preset rotating speed reduction current is the rated maximum current value representing whether the outdoor fan of the air conditioner needs to be adjusted to reduce the gear.
[0091] Specifically, after obtaining the fan phase current, the air conditioner compares the fan phase current with the preset rotating speed reduction current, and adjusts the current outdoor fan gear of the air conditioner according to the comparison result.
[0092] Optionally, if the fan phase current is greater than or equal to the preset rotating speed reduction current, the air conditioner determines that the outdoor fan of the air conditioner needs to be adjusted to reduce the gear, and then the air conditioner reduces the current outdoor fan gear of the air conditioner according to the preset gear reduction interval, until the fan phase current of the air conditioner is less than or equal to the preset rotating speed reduction current threshold, to obtain a target outdoor fan gear. The rotating speed reduction current threshold is calculated by the preset rotating speed reduction current and a preset current coefficient, i.e., the rotating speed reduction current threshold is the difference between the preset rotating speed reduction current and the preset current coefficient. In a specific example, the preset current coefficient is 50 mA (unit: milliampere), and the rotating speed reduction current threshold is the preset rotating speed reduction current minus 50 mA.
[0093] Optionally, in one specific embodiment, the air conditioner determines that the current outdoor fan gear of the air conditioner is a high wind gear after responding to the air conditioner control request, and the high wind gear has an outdoor fan rotating speed of 750 r / min (unit: revolutions per minute). The high wind gear corresponds to a wind pressure difference set value of 5 Pa (unit: Pascal). The air conditioner further obtains a current wind pressure difference detection value, and compares the wind pressure difference detection value, the wind pressure difference set value, and a preset wind pressure difference control value to adjust the target outdoor fan rotating speed of the high wind gear. The preset wind pressure difference control value is 0.5 Pa (unit: Pascal).
[0094] Specifically, the air conditioner calculates a first wind pressure difference control threshold value of 5.5 Pa and a second wind pressure difference control threshold value of 4.5 Pa for the high wind gear according to the wind pressure difference set value and the preset wind pressure difference control value. The air conditioner compares the wind pressure difference detection value with the first wind pressure difference control threshold value and the second wind pressure difference control threshold value to determine the adjustment strategy of the outdoor fan at the high wind gear, i.e., if the wind pressure difference detection value is greater than the first wind pressure difference control threshold value 5.5 Pa, the air conditioner reduces the outdoor fan rotating speed by 1% every 60 seconds based on the rotating speed of 750 r / min until the wind pressure difference detection value is within the interval formed by the first wind pressure difference control threshold value and the second wind pressure difference control threshold value or the outdoor fan rotating speed is reduced to the minimum outdoor fan rotating speed of 300 r / min.
[0095] If the wind pressure difference detection value is less than the second wind pressure difference control threshold value 4.5 Pa, the air conditioner increases the outdoor fan rotating speed by 1% every 60 seconds based on the rotating speed of 750 r / min until the wind pressure difference detection value is within the interval formed by the first wind pressure difference control threshold value and the second wind pressure difference control threshold value or the outdoor fan rotating speed is increased to the maximum outdoor fan rotating speed of 1000 r / min.
[0096] Specifically, the air conditioner further obtains a fan phase current and compares the fan phase current with a preset speed reduction current of 850 mA (unit: milliampere) to adjust the current outdoor fan gear and obtain a target outdoor fan gear, i.e., if the fan phase current is greater than or equal to the preset speed reduction current of 850 mA, the air conditioner reduces the current outdoor fan gear of the air conditioner by one gear according to a preset gear reduction interval of 20 s until the fan phase current is less than or equal to a speed reduction current threshold value of 800 mA, records the current outdoor fan gear, and sets the current outdoor fan gear as the target fan gear.
[0097] Specifically, after adjusting the wind gear of the air conditioner, the air conditioner can also respond to a wind gear adjustment request for the air conditioner and obtain an updated fan phase current, where the updated fan phase current is the real-time phase current of the outdoor fan in the air conditioner.
[0098] Specifically, after obtaining the updated fan phase current of the air conditioner, the air conditioner further obtains the historical wind deflector adjustment time and the wind deflector adjustment times of the air conditioner, and updates the target outer fan gear position according to the updated fan phase current, the historical wind deflector adjustment time and the wind deflector adjustment times, to obtain an updated outer fan gear position.
[0099] In this embodiment, the air conditioner obtains the wind pressure difference detection value of the air conditioner and the current outer fan gear position of the air conditioner in response to the air conditioning control request for the air conditioner, adjusts the rotation speed of the outer fan in the air conditioner according to the wind pressure difference detection value, the wind pressure difference setting value of the current outer fan gear position and the preset wind pressure difference control value, obtains the target outer fan rotation speed of the current outer fan gear position, adjusts the current outer fan gear position of the air conditioner according to the fan phase current corresponding to the target outer fan rotation speed and the preset rotation speed reduction current, obtains the target outer fan gear position, and controls the air conditioner to adjust the air conditioning operation state of the air conditioner according to the target outer fan gear position. The outer fan rotation speed control of the outer fan of the air conditioner is realized according to the linkage of the wind pressure difference of the outer fan of the air conditioner and the fan phase current, so that the air conditioner can cover more possible environmental operation conditions of the outdoor unit, and the working performance of the air conditioner is improved.
[0100] As shown in Figure 3 , Figure 3 The flowchart of one embodiment of the air conditioner control method provided in this embodiment is shown in the figure. Specifically, in this embodiment, the air conditioner control method further includes steps 301-302:
[0101] 301, obtaining the high-load phase current of the air conditioner at the target outer fan gear position, and generating the wind gear load threshold of the air conditioner according to the high-load phase current and a preset coefficient;
[0102] 302, if the updated fan phase current is less than or equal to the wind gear load threshold, the historical wind deflector adjustment time is greater than a preset adjustment interval threshold, and the wind deflector adjustment times are less than a preset adjustment times threshold, the target outer fan gear position is increased to obtain an updated outer fan gear position.
[0103] Based on the above embodiment, in this embodiment, after adjusting the outer fan gear position according to the fan phase current corresponding to the target outer fan rotation speed, the air conditioner further responds to the wind gear adjustment request for the air conditioner to further adjust the fan gear position of the air conditioner to obtain an updated outer fan gear position, and controls the air conditioner to adjust the air conditioning operation state of the air conditioner according to the updated outer fan gear position.
[0104] Specifically, the air conditioner obtains a high-load phase current at a target outdoor fan gear position, and generates a wind gear load threshold of the target outdoor fan gear position according to the high-load phase current and a preset coefficient. The high-load phase current is a fan phase current when a fan phase current of the target outdoor fan gear position is less than or equal to a drop speed current threshold. After obtaining the high-load phase current, the air conditioner calculates a difference between the high-load phase current and the preset coefficient to obtain the wind gear load threshold of the air conditioner. In an embodiment, the preset coefficient is 100 mA.
[0105] Specifically, after obtaining the wind gear adjustment request for the air conditioner, the air conditioner further obtains a historical wind gear adjustment time and a wind gear adjustment frequency of the air conditioner, and compares the historical wind gear adjustment time with a preset adjustment interval threshold, compares the updated fan phase current with the wind gear load threshold, and compares the wind gear adjustment frequency with a preset adjustment frequency threshold, to determine whether the outdoor fan needs to be adjusted to a higher gear position. The historical wind gear adjustment time is an interval time from the last time the outdoor fan gear position is adjusted by the fan phase current. The wind gear adjustment frequency is a number of times that the outdoor fan gear position is adjusted to a higher gear position within a preset time period.
[0106] Optionally, if the updated fan phase current of the air conditioner is less than or equal to the wind gear load threshold, the historical wind gear adjustment time is greater than the preset adjustment interval threshold, and the wind gear adjustment frequency is less than the preset adjustment frequency threshold, the air conditioner increases the target outdoor fan gear position to an outdoor fan gear position corresponding to the updated fan phase current to obtain an updated outdoor fan gear position of the air conditioner, and controls the air conditioner to adjust an air conditioning operation state of the air conditioner according to the updated outdoor fan gear position. In an embodiment, the preset adjustment interval threshold is 10 minutes. The preset adjustment frequency threshold is 5 times. That is, if the historical wind gear adjustment time from the last time the fan phase current is adjusted to a lower gear position has passed 10 minutes, the updated fan phase current of the air conditioner is less than the wind gear load threshold (a difference between the high-load phase current and the preset coefficient 100 mA), and the wind gear adjustment frequency is less than the preset adjustment frequency 5 times, the air conditioner increases the target outdoor fan gear position to the outdoor fan gear position corresponding to the updated fan phase current to obtain the updated outdoor fan gear position, and the air conditioner operates according to the updated outdoor fan gear position.
[0107] In this embodiment, the air conditioner obtains a high-load phase current at a target outdoor fan gear position, and generates a wind gear load threshold of the air conditioner according to the high-load phase current and a preset coefficient. If the updated fan phase current is less than or equal to the wind gear load threshold, the historical wind gear adjustment time is greater than a preset adjustment interval threshold, and the wind gear adjustment frequency is less than a preset adjustment frequency threshold, the target outdoor fan gear position is increased to obtain an updated outdoor fan gear position. The outdoor fan gear position is adjusted according to the fan phase current, and the working performance of the air conditioner is improved.
[0108] As Figure 4 shown, Figure 4 The flowchart of one embodiment of the air conditioner control method provided by the embodiment for adjusting the speed of the external fan is shown. Specifically, in the embodiment, the air conditioner control method further includes:
[0109] 401, obtaining the control protection deviation value of the air conditioner and the wind pressure difference detection fault value;
[0110] 402, if the wind pressure difference detection value is greater than or equal to the control protection deviation value, updating the speed of the external fan of the air conditioner to the preset minimum speed;
[0111] 403, if the wind pressure difference detection value is less than the wind pressure difference detection fault value, outputting the wind pressure detection abnormality prompt information.
[0112] Based on the above embodiment, in the embodiment, when the speed of the current external fan gear is adjusted according to the wind pressure difference detection value, the control protection deviation value and the wind pressure difference detection fault value of the air conditioner are also obtained, wherein the control protection deviation value is a protection deviation threshold value for detecting whether the wind pressure difference of the air conditioner is abnormal. The wind pressure difference detection fault value is a detection threshold value for detecting whether the wind pressure difference sensor of the air conditioner is abnormal. In one specific embodiment, the wind pressure difference fault detection value is 0.5 pa.
[0113] Optionally, if the wind pressure difference detection value is greater than or equal to the control protection deviation value and the duration exceeds the preset first time threshold value, the air conditioner outputs the pressure difference abnormality protection flag to the air conditioner indoor unit and outputs the prompt information of the pressure difference abnormality to the user, and updates the speed of the external fan of the air conditioner to the preset minimum speed. Until the wind pressure difference detection value is less than the control protection deviation value and the duration exceeds the second time threshold value, the air conditioner updates the speed of the external fan to the target speed of the current external fan gear. In one specific embodiment, the first time threshold value is 2 min (unit: min), and the second time threshold value is 1 min.
[0114] Optionally, the air conditioner also judges whether the wind pressure difference sensor is abnormal according to the wind pressure difference detection value and the wind pressure difference detection fault value. That is, when the air conditioner is in a running state, if the external fan is started, if the wind pressure difference detection value is detected to be less than the wind pressure difference detection fault value in a continuous time period, the air conditioner outputs the wind pressure difference sensor fault prompt information and stops using the wind pressure difference detection value for external fan speed adjustment until the wind pressure difference detection value is detected to be greater than or equal to the wind pressure difference detection fault value in a continuous time period. The air conditioner outputs the fault recovery prompt information and enables the wind pressure difference detection value for external fan speed adjustment.
[0115] In the embodiment, the air conditioner obtains a control protection deviation value and a wind pressure difference detection fault value of the air conditioner; if the wind pressure difference detection value is greater than or equal to the control protection deviation value, the outer fan speed of the air conditioner is updated to a preset minimum speed; and if the wind pressure difference detection value is less than the wind pressure difference detection fault value, a wind pressure detection abnormality prompt information is output. The control effectiveness of the wind pressure difference detection value adjustment speed control logic is improved, and the performance of the air conditioner is prevented from being reduced due to the adjustment of the fan speed in the wind pressure difference detection fault condition.
