Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
It should be noted that all the actions of acquiring signals, information or data in the present application are performed under the premise of complying with the corresponding data protection regulation policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
Fig. 1 is a flowchart illustrating a method for determining an insufficient refrigerant of an air conditioner according to an exemplary embodiment. The method can be applied to a server communicating with an air conditioner. As shown in fig. 1, the method may include S101 to S104.
And S101, acquiring the operation data of the target air conditioner.
The operation data comprises a first type of operation data and a second type of operation data.
Illustratively, the operation data acquired by the server is uploaded by the target air conditioner. And under the condition that the target air conditioner is not in an air supply mode and the running time reaches the preset time, the target air conditioner can upload the running data of the target air conditioner to the server. The preset time period may range from 10min to 30min, for example, may be set to 20min, and the setting of the preset time period may ensure the stability of the operation of the target air conditioner. The air conditioner is in the air supply mode, and the compressor is out of work, and refrigerant system can't discharge the heat, through the rotation of fan, drives indoor air flow, promotes the air convection, that is to say, the air conditioner air supply mode does not involve the consumption to refrigerants such as freon. Therefore, in order to reduce the energy consumption of the air conditioner, the target air conditioner may not upload its own operation data to the server in the case where the target air conditioner is in the air supply mode.
The first type of operation data and the second type of operation data are data which can represent the operation state of the air conditioner and can be classified based on different purposes. The first type of operating data may be used to determine first target reference operating data, and then a threshold condition for a second type of operating data of the target air conditioner may be determined from the first target reference operating data, and the second type of operating data of the target air conditioner may be used to compare with the determined threshold condition to determine whether the refrigerant of the target air conditioner is insufficient. For example, the first operational data may include an indoor ambient temperature, an outdoor ambient temperature, and the second operational data may include an indoor coil temperature, an outdoor coil temperature.
S102, determining first target reference operation data from the stored operation data of other air conditioners, wherein the operation data of other air conditioners comprise first type operation data and second type operation data of other air conditioners, and the first type operation data in the first target reference operation data is matched with the first type operation data of the target air conditioner.
For example, the operation data of other air conditioners may be stored in the database on the server side in advance. The other air conditioners stored in the database may be air conditioners of the same model as the target air conditioner, and the operation data of air conditioners of different models may be stored in different databases. When the server obtains the operation data of the target air conditioner, the server can determine a plurality of operation data of other air conditioners matched with the first type of operation data of the target air conditioner from the database. The first target reference operation data may include operation data of a plurality of other air conditioners.
Taking the first type of operation data including the indoor environment temperature, the outdoor environment temperature, the compressor frequency and the indoor fan gear as an example, the corresponding indoor environment temperature range can be determined according to the indoor environment temperature t1 of the target air conditioner, for example, the indoor environment temperature range can be [ t1-1, t1+1], and the temperature unit is; the corresponding outdoor environment temperature range can be determined according to the outdoor environment temperature t2 of the target air conditioner, for example, the outdoor environment temperature range can be [ t2-1.5, t2+1.5], and the temperature unit is; the corresponding compressor frequency range may be determined according to the compressor frequency f0 of the target air conditioner, for example, the compressor frequency range may be [ f0-1, f0+1], and the frequency unit is Hz; if the indoor environment temperature in the operation data of the air conditioner A stored in the database is within the range of the indoor environment temperature, the outdoor environment temperature is within the range of the outdoor environment temperature, the compressor frequency is within the frequency range of the compressor, and the gear of the indoor fan of the air conditioner A is the same as the gear of the indoor fan of the target air conditioner, it can be determined that the first type of operation data of the air conditioner A is matched with the first type of operation data of the target air conditioner.
Therefore, the operation data of a plurality of other air conditioners matched with the first type of operation data of the target air conditioner can be determined, and the first target reference operation data is further determined. The smaller the indoor environment temperature range, the outdoor environment temperature range and the compressor frequency range are, the higher the referenceability of the determined first target reference operation data is, that is, the higher the similarity with the operation data of the target air conditioner is, the more accurate the result of whether the refrigerant of the target air conditioner is insufficient is determined.
And S103, determining a threshold condition of second type of operation data aiming at the target air conditioner according to the first target reference operation data.
For example, the threshold condition of the second type of operation data for the target air conditioner may be determined according to the second type of operation data in the first target reference operation data. For example, taking the indoor coil temperature as the second type of operation data as an example, if the first target reference operation data includes a plurality of operation data of other air conditioners that match the first type of operation data of the target air conditioner, any one of an average value, a median, or a mode of the indoor coil temperature in the operation data of the plurality of other air conditioners may be determined as the threshold related to the indoor coil temperature.
And S104, determining whether the refrigerant of the target air conditioner is insufficient according to the second type of operation data of the target air conditioner and the threshold condition.
For example, if it is determined that the target air conditioner has insufficient refrigerant, a prompt message may be generated, which may be used to prompt the user of the insufficient refrigerant. For example, a prompt message of 'insufficient refrigerant, please deal with in time' can be displayed through a display screen of the target air conditioner to prompt a user; the prompt information can be sent to an intelligent terminal bound with the target air conditioner, and a user is prompted through the intelligent terminal, wherein the intelligent terminal can comprise an intelligent mobile phone, an intelligent tablet and other electronic equipment. For another example, a speaker may be further disposed in the target air conditioner, and the above prompt information may be broadcasted through the speaker in a voice manner to prompt the user. Thus, the use experience of the user can be improved.
The threshold condition is determined based on the screened operation data of other air conditioners, and the determined threshold condition can be adapted to the current operation state of the target air conditioner, so that the accuracy of a result for judging whether the refrigerant of the target air conditioner is insufficient can be improved, and the actual experience effect of a user is improved.
In the technical scheme, through the first type of operation data in the operation data of the target air conditioner, the first target reference operation data matched with the first type of operation data of the target air conditioner can be determined from the stored operation data of other air conditioners; determining a threshold condition for a second type of operating data of the target air conditioner according to the first target reference operating data; and determining whether the refrigerant of the target air conditioner is insufficient according to the second type of operation data of the target air conditioner and the threshold condition. Therefore, the determined threshold condition can be adapted to the current running state of the target air conditioner, the accuracy of the result of judging whether the target air conditioner refrigerant is insufficient is improved, and the actual experience effect of a user is improved.
Optionally, the operation data of the target air conditioner may further include a third type of operation data of the target air conditioner, and the operation data of the other air conditioners may further include a third type of operation data of the other air conditioners.
The first type of operation data may include an indoor ambient temperature, an outdoor ambient temperature, a compressor frequency, and an indoor fan gear; the second type of operational data may include indoor coil temperature, outdoor coil temperature, discharge air temperature, and compressor power; the third type of operation data includes an air conditioner installation location and a total air conditioner operation time period.
Illustratively, for a first type of operational data: the indoor ambient temperature can be acquired by a temperature sensor arranged indoors, the outdoor ambient temperature can be acquired by a temperature sensor arranged outdoors, and the compressor frequency can be acquired by a frequency sensor arranged on the compressor in advance. For the second class of operational data: the temperature of an indoor coil can be obtained through a temperature sensor arranged on the coil (an indoor evaporator) of an indoor unit of the air conditioner; the temperature of an outdoor coil can be obtained through a temperature sensor arranged on the coil (an outdoor condenser) of the outdoor unit of the air conditioner; a temperature sensor can be arranged on a position, which is a certain distance away from an exhaust port, on an exhaust pipe of a compressor of the air conditioner, and the exhaust temperature is obtained through the temperature sensor; the compressor power can be obtained by a power sensor preset on the compressor. For the third class of operational data: the air conditioner installation position can be determined by a GPS (global positioning system) carried in the air conditioner when the air conditioner is installed, and can also be input by a user. The total time period for which the air conditioner is operated may be determined by a timer in the air conditioner.
Optionally, in S103, determining a threshold condition for the second type of operation data of the target air conditioner according to the first target reference operation data may include:
determining a first threshold condition for second type operation data of the target air conditioner according to the second type operation data in the first target reference operation data;
determining second target reference operation data from the first target reference operation data, wherein third type operation data in the second target reference operation data is matched with third type operation data of the target air conditioner;
and determining a second threshold condition aiming at the second type of operation data of the target air conditioner according to the second type of operation data in the second target reference operation data, wherein the threshold condition comprises a first threshold condition and a second threshold condition.
Wherein the first threshold condition may include a first indoor coil temperature threshold, a first outdoor coil temperature threshold, a first discharge air temperature threshold, and a first compressor power threshold, and the second threshold condition may include a second indoor coil temperature threshold, a second outdoor coil temperature threshold, a second discharge air temperature threshold, and a second compressor power threshold.
For example, determining a first threshold condition for a second type of operating data of the target air conditioner according to a second type of operating data of the first target reference operating data may include:
determining an average value of the indoor coil temperatures in the first target reference operation data as a first indoor coil temperature threshold in a first threshold condition;
determining an average value of the outdoor coil temperature in the first target reference operation data as a first outdoor coil temperature threshold in a first threshold condition;
determining an average of the exhaust temperatures in the first target reference operation data as a first exhaust temperature threshold in the first threshold condition;
the average value of the compressor powers in the first target reference operation data is determined as the first compressor power threshold in the first threshold condition.
The operation state of the air conditioner is often affected by the installation location and the service life, in addition to the actual ambient temperature. The longer the total time of the air conditioner operation, the more likely the air conditioner has a problem of insufficient refrigerant, and the higher the probability that the air conditioner having the same state is. Different installation positions of the air conditioners can cause different aging degrees of the air conditioners, and further different influences are generated on the operation states of the air conditioners, wherein the position factors influencing the operation states of the air conditioners in the same area are the same or similar. Therefore, the second target reference operation data which is matched with the target air conditioner operation state more highly can be further screened from the first target reference operation data through the third type of operation data.
For example, the total air conditioner operation time period T may be determined according to the target air conditioner General (1) Determining the corresponding total air conditioner operation time range, for example, the total air conditioner operation time range may be [ t1-10, t1+10 ]]The time unit can be min; the installation location range may be determined according to the installation location of the target air conditioner. If the total air conditioner operation time length of the air conditioner B in the first target reference operation data is within the total air conditioner operation time length range and the installation position is within the installation position range, it can be determined that the third type of operation data of the air conditioner B is matched with the third type of operation data of the target air conditioner. In this way, the second target reference operation data which is more highly matched with the target air conditioner operation state can be determined from the first target reference operation data. Wherein, the smaller the total operating time range and the installation position range of the air conditioner are,the higher the referenceability of the determined second target reference operation data, that is, the higher the similarity of the operation data of the target air conditioner, the more accurate the result of whether the target air conditioner refrigerant is insufficient is determined to be.
For example, determining a second threshold condition for a second type of operating data of the target air conditioner according to a second type of operating data of the second target reference operating data may include:
determining the product of the average value of the indoor coil temperatures in the second target reference operation data and the first coefficient as a second indoor coil temperature threshold in a second threshold condition;
determining the product of the average value of the outdoor coil temperature in the second target reference operation data and the second coefficient as a second outdoor coil temperature threshold in a second threshold condition;
determining a product of the average value of the exhaust temperatures in the second target reference operation data and the third coefficient as a second exhaust temperature threshold in the second threshold condition;
determining a product of the average value of the compressor power in the second target reference operation data and the fourth coefficient as a second compressor power threshold in the second threshold condition;
when the target air conditioner is in a refrigeration mode or a defrosting mode, the first coefficient and the third coefficient are greater than 1, and the second coefficient and the fourth coefficient are less than 1;
when the target air conditioner is in the heating mode, the second coefficient and the third coefficient are greater than 1, and the first coefficient and the fourth coefficient are less than 1.
For example, the first coefficient, the second coefficient, the third coefficient, and the fourth coefficient may be calibrated in advance through experiments. For example, when the target air conditioner is in the cooling mode or the defrosting mode, the first coefficient and the third coefficient may be set to 1.05, and the second coefficient and the fourth coefficient may be set to 0.95; the second coefficient and the third coefficient may be set to 1.05, and the first coefficient and the fourth coefficient may be set to 0.95, when the target air conditioner is in the heating mode.
When the target air conditioner is in a refrigeration mode or a defrosting mode, the temperature threshold of the first indoor coil is smaller than the temperature threshold of the second indoor coil, the temperature threshold of the first outdoor coil is larger than the temperature threshold of the second outdoor coil, the temperature threshold of the first exhaust temperature is smaller than the temperature threshold of the second exhaust temperature, and the power threshold of the first compressor is larger than the power threshold of the second compressor;
when the target air conditioner is in a heating mode, the first indoor coil temperature threshold value is larger than the second indoor coil temperature threshold value, the first outdoor coil temperature threshold value is smaller than the second outdoor coil temperature threshold value, the first exhaust temperature threshold value is smaller than the second exhaust temperature threshold value, and the first compressor power threshold value is larger than the second compressor power threshold value.
In this way, the second threshold condition is more stringent than the first threshold condition, and the accuracy of the result of determining whether the refrigerant of the target air conditioner is insufficient can be improved.
Alternatively, in S104, determining whether the target air conditioner is insufficient in refrigerant according to the second type of operation data of the target air conditioner and the threshold condition may include:
and if the second type of operation data of the target air conditioner meets the first threshold condition and meets the second threshold condition, determining that the refrigerant of the target air conditioner is insufficient.
When the target air conditioner is in a refrigeration mode or a defrosting mode, if the temperature of an indoor coil of the target air conditioner is greater than a first indoor coil temperature threshold value, the temperature of an outdoor coil is less than a first outdoor coil temperature threshold value, the exhaust temperature is greater than a first exhaust temperature threshold value, and the compressor power is less than a first compressor power threshold value, it can be determined that second type of operation data of the target air conditioner meets a first threshold value condition;
when the target air conditioner is in a heating mode, if the temperature of an indoor coil of the target air conditioner is smaller than a first indoor coil temperature threshold value, the temperature of an outdoor coil is larger than a first outdoor coil temperature threshold value, the exhaust temperature is larger than a first exhaust temperature threshold value, and the compressor power is smaller than a first compressor power threshold value, it can be determined that second type operation data of the target air conditioner meets a first threshold value condition.
When the target air conditioner is in a refrigeration mode or a defrosting mode, if the temperature of the indoor coil of the target air conditioner is greater than a second indoor coil temperature threshold value, the temperature of the outdoor coil is less than a second outdoor coil temperature threshold value, the exhaust temperature is greater than a second exhaust temperature threshold value, and the compressor power is less than a second compressor power threshold value, it can be determined that second type of operation data of the target air conditioner meets a second threshold value condition;
when the target air conditioner is in the heating mode, if the temperature of the indoor coil of the target air conditioner is smaller than a second indoor coil temperature threshold value, the temperature of the outdoor coil is larger than a second outdoor coil temperature threshold value, the exhaust temperature is larger than a second exhaust temperature threshold value, and the compressor power is smaller than a second compressor power threshold value, it can be determined that second type of operation data of the target air conditioner meets a second threshold value condition.
For example, the first threshold condition is determined based on a first target reference operating data, the first target reference operating data having a greater number of samples than the second target reference operating data, and thus the determined first threshold condition has a higher universality. The second threshold condition is determined according to the second target reference operation data, and as described above, the second target reference operation data with higher matching degree with the target air conditioner operation state can be determined from the first target reference operation data through the third type of operation data, so that the influence of the installation position and the service life on the judgment result can be avoided. The second target reference operation data sample size is relatively small, and the similarity with the operation data of the target air conditioner is high, so that the pertinence of the determined second threshold condition is stronger. In this way, the accuracy of the result of determining whether the refrigerant of the target air conditioner is insufficient can be improved by setting the first threshold condition and the second threshold condition.
For another example, the preliminary determination may be made by using the second type of operation data of the target air conditioner and the first threshold condition, and for the target air conditioner for which the second type of operation data does not satisfy the first threshold condition, it may be determined that the target air conditioner is sufficient in refrigerant, and it is not determined whether the second type of operation data of the target air conditioner satisfies the second threshold condition. For a target air conditioner whose second type of operation data meets the first threshold condition, it may be determined whether the second type of operation data of the target air conditioner meets the second threshold condition. If so, determining that the target air conditioner refrigerant is insufficient; if not, the target air conditioning refrigerant may be determined to be sufficient. In most cases, the air conditioner is not lack of refrigerant, so that the data processing amount in the server can be greatly reduced and the judgment efficiency can be improved by preferentially judging whether the second type of operation data of the target air conditioner meets the first threshold condition.
