Therefore, the server can conveniently and timely acquire the operation data of a plurality of fault air conditioners.
The same operation state can be embodied as the same operation mode of a plurality of air conditioners, the same operation frequency of the compressors, the same rotating speed of the fan of the indoor unit and the same rotating speed of the fan of the outdoor unit. In this way, the plurality of air conditioners are under the same detection condition, and the subsequent accurate judgment of whether the refrigerant leakage fault occurs is facilitated.
The using time interval can be divided into using within 1 year, using within 1 year to using within 3 years, using within 3 years to using within 5 years and the like. In this regard, the embodiments of the present disclosure may not be particularly limited.
Fig. 1 is a flowchart of a control method for an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner, which may include:
s11, the processor obtains various current operation parameters of the air conditioners relevant to the refrigerant leakage fault and various historical operation parameters under different operation modes relevant to the various current operation parameters in the same service time interval.
Here, the various types of current operating parameters associated with a refrigerant leak fault may be embodied at least in one or more of current compressor power, current discharge air temperature, and current inside coil temperature.
Different operation modes can comprise a cooling mode and a heating mode. The cooling mode may refer to a working state of the air conditioner when the indoor heat exchanger is used as an evaporator to participate in an air conditioning process. For example, the normal cooling mode, the dehumidification mode, and the operation mode of the indoor heat exchanger frost condensation in the self-cleaning process or the outdoor heat exchanger defrosting in the self-cleaning process. The heating mode may refer to an operating state of the air conditioner in a case where the indoor heat exchanger participates in the air conditioning process as a condenser. For example, a normal heating mode, and a defrosting mode of the indoor heat exchanger in the self-cleaning process, or a high-temperature sterilizing mode of the indoor heat exchanger in the self-cleaning process.
In response, the historical operating parameters in different operating modes associated with the current operating parameters may be at least one or more of historical compressor power, historical discharge air temperature, and historical inner coil temperature in the cooling mode, and one or more of historical compressor frequency, historical discharge air temperature, and historical inner coil temperature in the heating mode.
Because the air conditioners are in the same operation state and the same use time interval, the refrigerant fault data of the multiple fault air conditioners in the same type have higher similarity and comparability, the subsequent processor is facilitated to analyze and obtain the change rule of various historical operation parameters along with time by obtaining various historical operation parameters of the multiple air conditioners in the same operation state and the same use time interval and in different operation modes of the multiple air conditioners in the same type in the same use time interval. In addition, since the usage time interval is in units of years, data needs to be classified to avoid that the data amount needing to be processed is too large to obtain the change rule.
Optionally, the embodiments of the present disclosure may provide multiple implementation manners to obtain various current operation parameters of the multiple air conditioners, which are respectively related to the refrigerant leakage fault, and various historical operation parameters in different operation modes associated with the various current operation parameters in the same usage duration interval. The following examples are given.
In one mode, if the processor can be respectively in communication connection with the plurality of air conditioners, the processor can directly acquire various current operation parameters of the plurality of air conditioners and acquire various historical operation parameters in different operation modes associated with the various current operation parameters in the same use time interval.
In another mode, if various current operation parameters of the plurality of air conditioners, which are related to the refrigerant leakage fault, and various historical operation parameters in different operation modes, which are related to various current operation parameters in the same use time interval, are stored in an air conditioner information base, which is stored in a server related to the processor, the processor can obtain various current operation parameters of the plurality of air conditioners and various historical operation parameters in different operation modes from the air conditioner information base in a local reading mode when needed. Or, if the air conditioner information base is stored in another data storage server, the processor may obtain various current operating parameters of the plurality of air conditioners stored in the air conditioner information base and various historical operating parameters in different operating modes by accessing the data storage server when necessary.
By adopting the mode, the processor can conveniently and quickly obtain various current operation parameters of the plurality of air conditioners, which are respectively related to the refrigerant leakage fault, and various historical operation parameters under different operation modes related to the various current operation parameters in the same use time interval.
And S12, respectively generating the change rule of various historical operating parameters of the plurality of air conditioners along with time in different operating modes by the processor.
Optionally, the generating, by the processor, a change rule of each type of historical operating parameters of the plurality of air conditioners with time in different operating modes may include: the processor obtains parameter variation of various historical operating parameters at adjacent time within the same using time interval; and the processor obtains corresponding change curves according to the variable quantities of various parameters in time sequence. Therefore, the change tracks of various historical operation parameters of the plurality of air conditioners in the same using time interval can be obtained, and the subsequent comparison of various current operation parameters of the plurality of air conditioners is facilitated, so that the leakage fault of the refrigerant can be detected automatically and timely, the manual detection is not needed, the maintenance time of maintenance personnel can be saved, and the use experience of a user is improved.
And S13, the processor determines a fault air conditioner which meets the preset fault condition in the plurality of air conditioners according to each change rule and the current operation parameters of the corresponding type, and sends a prompt to a user associated with the fault air conditioner.
Optionally, the determining, by the processor, a faulty air conditioner that satisfies a preset fault condition among the plurality of air conditioners according to each change rule and the current operation parameter of the corresponding type may include: the processor obtains current operation modes of a plurality of air conditioners; the processor obtains the absolute value of the maximum parameter difference between various historical operating parameters of the plurality of air conditioners and the current operating parameters of corresponding types from various change rules in the current operating mode; and under the condition that each absolute value of any air conditioner is greater than or equal to a preset parameter absolute value threshold in a preset fault condition, determining any air conditioner as a fault air conditioner by the processor. Because the operating parameters such as compressor power, exhaust temperature and coil pipe temperature can be caused to change when the refrigerant leakage fault occurs, the refrigerant leakage fault can be found in time by comparing the absolute values of the difference values between the historical operating parameters and the current operating parameters, and manual detection is not needed, so that the maintenance time of maintenance personnel can be saved, and the use experience of a user is improved.
Here, the embodiments of the present disclosure may provide various implementations to obtain the current operation modes of a plurality of air conditioners. The following examples are given.
In one mode, a user associated with each of the plurality of air conditioners may send an operation instruction including a current operation mode to the processor through the air conditioner control terminal, so that the processor determines the current operation mode according to the operation instruction. The air conditioner control terminal can be an air conditioner remote controller or terminal equipment which is in wireless communication with the air conditioner. And wireless communication modes comprise one or more of Wi-Fi communication, zigbee protocol communication and Bluetooth communication.
In another mode, the processor may obtain current indoor environment parameters of the respective rooms of the plurality of air conditioners, and control the air conditioners to operate in the corresponding operation modes according to the current indoor environment parameters. For example, according to the current indoor environment parameter, the corresponding operation mode is determined from the association relationship between the indoor environment parameter and the operation mode. Like this, help improving the intelligent degree of air conditioner, reduce user's operation complexity simultaneously, improve user's use and experience.
Alternatively, the preset parameter absolute value threshold may be determined as follows: the processor determines a preset threshold value set under different operation modes in preset fault conditions according to the current operation mode; and the processor determines a preset parameter absolute value threshold value of a corresponding type from the preset threshold value set according to the parameter type of each absolute value.
The variation of the air conditioner operation parameters under the refrigeration working condition and the heating working condition is different, so that an accurate preset parameter absolute value threshold can be obtained according to the operation mode of the air conditioner, the absolute value of the difference value between the historical operation parameter and the current operation parameter is compared with the preset parameter absolute value threshold, the refrigerant leakage fault can be accurately detected, and the missing detection or the false detection can be avoided.
Specifically, the determining, by the processor, the preset threshold value sets in different operation modes in the preset fault condition according to the current operation mode may include: under the condition that the current operation mode is a refrigeration mode, the processor determines that a preset threshold value set is a first threshold value set; under the condition that the current operation mode is the heating mode, the processor determines that the preset threshold value set is a second threshold value set; and the various preset parameter absolute value thresholds in the first threshold value set are smaller than the corresponding preset parameter absolute value thresholds in the second threshold value set. Because the variable quantity of the air conditioner operation parameter under the refrigeration working condition and the heating working condition is different, the arrangement is favorable for accurately and timely detecting the leakage fault of the refrigerant, the maintenance time of maintenance personnel can be saved, and the use experience of a user is improved.
In some embodiments, the first set of thresholds may be embodied as a preset internal coil temperature absolute threshold of 5 degrees celsius, a preset exhaust temperature absolute threshold of 15 degrees celsius, and a preset power absolute threshold of 50 watts.
The second threshold set may be embodied as a preset inner coil temperature absolute threshold of 6 ℃, a preset exhaust temperature absolute threshold of 18 ℃, and a preset power absolute threshold of 80 watts.
Optionally, the embodiments of the present disclosure may provide various implementation manners to send a reminder to a user associated with a faulty air conditioner, which is illustrated below.
In one mode, if the fault air conditioner is configured with the information reminding module, the processor triggers the information reminding module to send fault reminding information to the user by issuing a reminding instruction to the information reminding module. For example, the information reminding module can be embodied as a voice broadcasting module, and the fault type can be broadcasted through voice. Or, the information reminding module can be embodied as an air conditioner display screen, and the fault type can be displayed through the air conditioner display screen.
In another mode, if the processor can perform wireless communication with the terminal device associated with the user, the processor can directly send the fault reminding information to the terminal device for the user to check.
By adopting the control method for the air conditioner provided by the embodiment of the disclosure, various current operation parameters which are in the same operation state and in the same use time interval and are respectively related to the refrigerant leakage fault of a plurality of air conditioners of the same type are obtained, and the change rule of various historical operation parameters of the plurality of air conditioners along with time under different operation modes is generated, so that the faulty air conditioner meeting the preset fault condition is determined according to the change rule and the current operation parameters of the corresponding type, and the automatic detection of the refrigerant leakage fault is realized. Compared with the prior art, the refrigerant leakage fault can be found in time, manual detection is not needed, maintenance time of maintenance personnel can be saved, and use experience of users is improved.

s21, the processor obtains various current operation parameters of the air conditioners relevant to the refrigerant leakage fault and various historical operation parameters under different operation modes relevant to the various current operation parameters in the same using time interval.
S22, the processor determines abnormal parameters from various historical operating parameters and eliminates the abnormal parameters.

Therefore, the method helps to avoid the fact that the sample is not practical due to interference of human factors and other factors, so that the objective authenticity of data is recovered, the accuracy of the change rule is better guaranteed, automatic and accurate detection of the refrigerant leakage fault is realized, and the use experience of a user is further improved.
Specifically, the first parameter threshold may be obtained by:
Out 1 ＝Q 3 +a×(Q 3 -Q 1 )
wherein, out 1 Is a first parameter threshold, Q 3 Is upper quartile, Q 1 Is the lower quartile, and a is the anomaly coefficient.
Specifically, the second parameter threshold may be obtained by:

wherein, out 2 Is a second parameter threshold, Q 3 Is upper quartile, Q 1 Is the lower quartile, and a is the anomaly coefficient.
