One ambient parameter is contrasted, and judges whether air-conditioning occurs to leak fluorine；If each time according to the 3rd operational factor and the 3rd environment
Parameter judges that leakage fluorine occurs for air-conditioning, then alert.
By the second operational factor and second environment parameter that are gathered there may be error, therefore joined according to the second operation
When number and second environment parameter judge that leakage fluorine occurs for air-conditioning, leakage fluorine does not occur for possible air-conditioning.In order to avoid wrong report, in basis
After second operational factor and second environment parameter judge that leakage fluorine occurs for air-conditioning, air-conditioning and field of employment are carried out at least once again
Parameter acquisition, judge whether air-conditioning occurs according to the air conditioner operation parameters and field of employment ambient parameter that collect each time respectively
Fluorine is leaked, if the result judged each time, which is air-conditioning, occurs leakage fluorine, alert.So, by air-conditioning and making
Multiple parameter acquisition is carried out with place, judges that air-conditioning just sends alarm signal after leakage fluorine occurs according to the parameter collected each time
Breath, the probability of air-conditioning leakage fluorine wrong report is reduced, improves the experience of user.
Alternatively, as shown in figure 1,
After step 103, if it is determined that air-conditioning there occurs leakage fluorine, then can by the loudspeaker of air-conditioning, display screen or

Second operational factor (the 3rd operational factor) and second environment parameter (the 3rd ambient parameter) and the first operational factor and the first ring
The operational factor of air-conditioning and the ambient parameter of field of employment are contrasted during the air conditioner refrigerating that border parameter includes, if air-conditioning is in
Heating state, then by the second operational factor collected (the 3rd operational factor) and second environment parameter (the 3rd ambient parameter) with
The operational factor of air-conditioning and the ambient parameter of field of employment during the air-conditioning heating that the first operational factor and first environment parameter include
Contrasted.So as to which no matter air-conditioning is in refrigerating state or heats state, and Lou fluorine detection can be carried out to air-conditioning, is ensured
Carry out to air-conditioning the ageing of Lou fluorine detection.
Below by taking domestic air conditioning as an example, fluorine detection method is leaked to air-conditioning provided in an embodiment of the present invention and made further specifically
It is bright, as shown in Fig. 2 this method may comprise steps of：
Step 201：First operational factor of air-conditioning and the second environment parameter of field of employment when detecting air-conditioning stable operation.
In an embodiment of the invention, after air-conditioning is installed into field of employment, air-conditioning start operation a period of time, treat
After air-conditioning stable operation, the first operational factor of air-conditioning and the first environment parameter of field of employment are gathered.Wherein, the first operation ginseng
Number includes operational factor of the air-conditioning under refrigerating state and heating state during stable operation, correspondingly, first environment parameter air-conditioning
Under refrigerating state and heating state during stable operation field of employment ambient parameter.In addition, the first operational factor can include
Inner disc temperature, external disk temperature, electric current, wind speed and compressor frequency of air-conditioning etc., first environment parameter can be including the use of places
Indoor temperature and outdoor temperature etc..
For example, after air-conditioning A is installed into user A residence A, air-conditioning A is started shooting and carries out refrigerating operaton 20min, treats sky
After adjusting A stable, the first operational factor 1 of air-conditioning A inner disc temperature T1, compressor frequency P1 as air-conditioning A, collection are gathered
First environment parameters 1 of the residence A indoor temperature M1 and outdoor temperature N1 as residence A.When air-conditioning A is for the first time to heat state
During operation, run after air-conditioning A to stable state, collection air-conditioning A inner disc temperature T2, compressor frequency P2 is as air-conditioning A's
First operational factor 2, gather the first environment parameter 2 of residence A indoor temperature M2 and outdoor temperature N2 as residence A.
Step 202：Often pass through a detection cycle, gather the second operational factor of air-conditioning and the second environment of field of employment
Parameter.
In an embodiment of the invention, a detection cycle is preset, often by a detection cycle, is transported in air-conditioning
The second operational factor of air-conditioning and the second environment parameter of field of employment are detected in capable process.Wherein, the second operational factor institute
Identical with project included by the first operational factor including project, project included by second environment parameter is wrapped with first environment parameter
It is identical to include project.
For example, it is 24h to preset detection cycle, often by 24h, detected during air-conditioning A is run in air-conditioning A
The second operational factor 1 of disk temperature T3, compressor frequency P3 as air-conditioning A, gather residence A indoor temperature M3 and outdoor temperature
Second environment parameters 1 of the N3 as residence A.
Step 203：Judge whether air-conditioning occurs to leak fluorine according to the second operational factor and second environment parameter, if it is, holding
Row step 204, otherwise terminates current process.

The first indoor temperature and the first outdoor temperature are obtained from first environment parameter, the second inner disc temperature is obtained from the second operational factor
Degree and the second compressor frequency, obtain the second indoor temperature and the second outdoor temperature from second environment parameter.If following three
Individual Rule of judgment is satisfied by, and is judged that leakage fluorine occurs for air-conditioning, is correspondingly performed step 204, otherwise judges that air-conditioning does not occur to leak fluorine,
Terminate current process.
Wherein, three Rule of judgment are respectively：
(1) second indoor temperature and the absolute value of the second inner disc temperature gap are less than the first indoor temperature and the first inner disc temperature
Spend the absolute value of difference；
(2) second indoor temperatures and the absolute value of the outer temperature gap of second Room are less than the first indoor temperature and the first outdoor temp
Spend the absolute value of difference；
The duration that (3) second compressor frequencies are more than the first compressor frequency reaches default critical duration.
For example, the second operational factor 1 and second environment parameter 1 in air-conditioning A collect in process of refrigerastion, if
| M3-T3 | ＜ | M1-T1 |, and | M3-N3 | ＜ | M1-N1 |, and P3 ＞ P1 duration exceedes critical duration 10min, then sentences
Disconnected air-conditioning A correspondingly performs step 204, otherwise terminates current process there occurs leakage fluorine.
Step 204：Parameter acquisition at least once is carried out to air-conditioning and field of employment, obtains the 3rd fortune collected each time
Row parameter and the 3rd ambient parameter.

Afterwards, parameter acquisition at least once is carried out to air-conditioning and field of employment, parameter acquisition all gathers the 3rd operation ginseng of air-conditioning each time
Number and the 3rd ambient parameter of field of employment.Wherein, project included by the 3rd operational factor and item included by the first operational factor
Mesh is identical, and project included by the 3rd ambient parameter is identical with project included by first environment parameter.
For example, 2 subparameter collections continuously are carried out to air-conditioning A and residence A, by the inner disc temperature collected each time and compression
Acc power corresponds to the 3rd operational factor of this collection as air-conditioning A, by the indoor temperature collected each time and outdoor temperature
The 3rd ambient parameter of this collection is corresponded to as residence A.
Step 205：The 3rd operational factor and the 3rd ambient parameter obtained according to parameter acquisition each time, judge respectively empty
Whether tune occurs to leak fluorine.
In an embodiment of the invention, the 3rd operational factor and the 3rd ambient parameter parameter acquisition each time obtained
Contrasted with the first operational factor and first environment parameter, judge whether air-conditioning occurs to leak fluorine.Specifically, according to the 3rd operation
Parameter and the 3rd ambient parameter judge whether air-conditioning occurs to leak the method for fluorine and according to the second operational factor and second environment parameter
Judge air-conditioning whether occur leak fluorine method it is consistent, due to whether judging air-conditioning according to the second operational factor and second environment parameter
The method that leakage fluorine occurs describes in detail in step 203, herein no longer to according to the 3rd operational factor and the 3rd ambient parameter
Judge air-conditioning whether occur leak fluorine method repeated.
For example, the 3rd operational factor and the 3rd ambient parameter that are obtained according to the collection of 2 subparameters judge that air-conditioning A leaks
Fluorine.
Step 206：Judge whether air-conditioning hair is judged according to the 3rd operational factor of each acquisition and the 3rd ambient parameter
Raw leakage fluorine, if it is, performing step 207, otherwise terminates current process.
In an embodiment of the invention, whether the judged result judged each time in judgment step 205 is to be, if
It is correspondingly to perform step 207, otherwise terminate current process.
Step 207：Alert.
In an embodiment of the invention, by judge at least twice air-conditioning occur leakage fluorine after, alert.Tool
Body, loudspeaker that can be by air-conditioning, display screen alert, mobile intelligent terminal that can also be to user and high in the clouds
Server sends warning message.
For example, after 3 times judge that leakage fluorine occurs for air-conditioning A, alarm message reminding user A is sent to user A mobile phone
Repaired, while warning message is sent to cloud server so that air-conditioning A after-sale service department can learn air-conditioning A
State.
