Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same 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.

It should be noted that all 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.
In the related technology, whether the air conditioner runs lack of fluorine is generally judged by the difference between the temperature of the coil of the heat exchanger of the air conditioner and the indoor environment temperature, the method depends on a large number of tests to determine the temperature difference threshold value for judging whether the air conditioner lacks of fluorine, namely the temperature difference threshold value between the temperature of the coil of the heat exchanger and the environment temperature, the temperature difference threshold value cannot cover the use environments of all the air conditioners, whether the air conditioner lacks of fluorine can be judged by the temperature difference threshold value in some environments, but whether the air conditioner lacks of fluorine cannot be judged by the temperature difference threshold value in some environments, the condition of a fluorine deficiency false alarm exists, or the condition that the actual fluorine deficiency of the air conditioner is not detected.
In view of this, the present disclosure provides a method, an apparatus, a medium and a chip for detecting fluorine deficiency in an air conditioner, so as to improve the accuracy of detecting fluorine deficiency in an air conditioner.
Fig. 1 is a flowchart illustrating an air conditioner fluorine deficiency detection method, which may be applied to a server, according to an exemplary embodiment, and may include S101 to S103, as shown in fig. 1.
In S101, fluorine-lacking characteristic information of the target air conditioning device and fluorine-lacking characteristic information of other air conditioning devices in the area corresponding to the target air conditioning device are obtained.
The target air conditioning device may be any air conditioning device, and the area corresponding to the target air conditioning device may be an area near the target air conditioning device. All can be configured with communication module in target air conditioning equipment and other air conditioning equipment, this communication module for example be the WIFI module, can communicate between networking back and the server.
In one embodiment, the target air conditioner and other air conditioners can both locally determine own fluorine-lacking characteristic information and send the information to the server. In another embodiment, the server may also determine the fluorine-deficient characteristic information of the target air conditioner and the other air conditioners respectively. In this embodiment, information such as sensor data, compressor frequency, and opening degree of the electronic expansion valve of the target air conditioning equipment may be sent to the server in real time through the communication module, and the server may determine the fluorine deficiency characteristic information of the target air conditioning equipment according to the information. Similarly, other air-conditioning equipment can also send the operation data to the server in real time, and the server can determine the fluorine-lacking characteristic information of other air-conditioning equipment. The fluorine-lack characteristic information of the air-conditioning equipment is used for representing the possibility of fluorine lack of the air-conditioning equipment, and the higher the fluorine-lack characteristic information of the air-conditioning equipment is, the higher the possibility of fluorine lack of the air-conditioning equipment can be represented.
In S102, a fluorine-lacking confidence of the target air conditioner is determined according to the fluorine-lacking characteristic information of the target air conditioner and the fluorine-lacking characteristic information of the other air conditioners.
In S103, it is determined whether the target air conditioning device is operating in the absence of fluorine according to the confidence of the absence of fluorine.
For example, the fluorine-lacking confidence of the target air conditioner may be determined according to the ranking condition of the fluorine-lacking characteristic information of the target air conditioner in other air conditioners, and if the fluorine-lacking characteristic information of the target air conditioner is higher than X% of other air conditioners, the fluorine-lacking confidence of the target air conditioner is X%, for example, if the fluorine-lacking characteristic information of the target air conditioner is higher than 80% of the fluorine-lacking characteristic information of the other air conditioners, the fluorine-lacking confidence of the target air conditioner is 80%.
In this way, considering that whether the fluorine deficiency is judged only according to the operation data of the target air conditioning equipment, the judgment is easily influenced by environmental factors, in the disclosure, when the fluorine deficiency detection is carried out, the fluorine deficiency characteristic information of other air conditioning equipment is considered at the same time, the other air conditioning equipment is the equipment in the area corresponding to the target air conditioning equipment, the influence of the environmental factors in the area can be reduced as much as possible, and the accuracy of the fluorine deficiency detection on the target air conditioning equipment is improved based on the data of the other air conditioning equipment in the area.
According to the technical scheme, the fluorine-lacking characteristic information of the target air-conditioning equipment and the fluorine-lacking characteristic information of other air-conditioning equipment in the area corresponding to the target air-conditioning equipment are obtained, the fluorine-lacking confidence coefficient of the target air-conditioning equipment is determined according to the fluorine-lacking characteristic information of the target air-conditioning equipment and the fluorine-lacking characteristic information of other air-conditioning equipment, and whether the target air-conditioning equipment runs in a fluorine-lacking mode or not is determined according to the fluorine-lacking confidence coefficient. Therefore, whether the fluorine deficiency is caused is not judged only according to the operation data of the target air conditioning equipment, other air conditioning equipment is equipment in the area corresponding to the target air conditioning equipment, the fluorine deficiency characteristic information of the other air conditioning equipment is considered, the influence of environmental factors in the area can be reduced as much as possible, and the accuracy of fluorine deficiency detection on the target air conditioning equipment can be improved based on the data of the other air conditioning equipment in the area.
In the present disclosure, the fluorine deficiency characteristic information of the air conditioning equipment may be determined by:
acquiring the opening of an electronic expansion valve, the exhaust temperature of a compressor and the frequency of the compressor when the starting operation time of the air conditioning equipment reaches a first preset time;
and determining the fluorine-lack characteristic information of the air conditioning equipment according to the opening of the electronic expansion valve, the exhaust temperature of the compressor and the frequency of the compressor.
The first preset time period may be preset, and may be set according to the time when the air conditioner enters the steady-state operation, for example, 20 minutes, after the start-up operation time period of the air conditioning equipment reaches 20 minutes, the air conditioner basically enters the steady-state operation, and the opening of the electronic expansion valve, the exhaust temperature of the compressor, and the frequency of the compressor when the air conditioning equipment operates for 20 minutes may be obtained.
Wherein, the compressor discharge temperature is the temperature at the compressor outlet position, and the compressor outlet position can be provided with temperature sensor for detecting the compressor discharge temperature. In the embodiment of determining the fluorine-lack characteristic information by the server, the opening of the electronic expansion valve of the air conditioning equipment, the exhaust temperature of the compressor and the frequency of the compressor can be all sent to the server in real time through the communication module integrated on the equipment, and the server can determine the fluorine-lack characteristic information of the air conditioning equipment according to the information.
For example, the fluorine-deficient characteristic information of the air conditioning equipment can be determined by the following formula:
α＝(lnP-4)*T exhaust gases /(F+90)
Wherein alpha represents the fluorine deficiency characteristic information, P represents the opening degree of the electronic expansion valve, T Exhaust of gases Indicating compressor discharge temperature and F compressor frequency.
Wherein, no matter the target air conditioner or other air conditioners, the fluorine-lack characteristic information of the device can be determined by the method introduced above.
In this disclosure, other air conditioners in the area corresponding to the target air conditioner may be determined as follows:
acquiring geographical position information of target air conditioning equipment;
and taking the air-conditioning equipment in the area with the distance to the geographical location information smaller than the preset distance threshold value as other air-conditioning equipment, or taking the air-conditioning equipment in the administrative area where the geographical location information is located as other air-conditioning equipment.
The target air conditioning equipment can locate the position of the target air conditioning equipment and send the geographic position information to the server through the communication module, wherein the geographic position information can be latitude and longitude information or coordinate information. In an embodiment, an area where a distance between the server and the geographical location information of the target air conditioner is smaller than a preset distance threshold may be used as an area corresponding to the target air conditioner, for example, an area formed by taking the geographical location information of the target air conditioner as a center of a circle and taking the preset distance threshold as a radius, and the air conditioners in the area may be used as other air conditioners, where the preset distance threshold may be preset. In another embodiment, an administrative region where the geographical location information of the target air conditioning device is located, for example, an administrative district or administrative county, may be used as the region corresponding to the target air conditioning device, and the air conditioning devices in the region may be used as other air conditioning devices.
Through the scheme, the air conditioning equipment can upload the geographical position information of the air conditioning equipment to the server, the server can determine other air conditioning equipment nearby the target air conditioning equipment according to the geographical position information of each air conditioning equipment, and meanwhile, the fluorine-lacking characteristic information of other air conditioning equipment is considered, so that the influence of environmental factors in the area can be reduced as much as possible, and the accuracy of fluorine-lacking detection on the target air conditioning equipment is improved.
