Judge air-conditioning whether occur leak fluorine method it is consistent, due to whether judging air-conditioning according to the second operating parameter and second environment parameter
The method that leakage fluorine occurs is described in detail in step 203, herein no longer to according to third operating parameter and third environmental parameter
Judge air-conditioning whether occur leak fluorine method repeated.
For example, the third operating parameter and third environmental parameter that are obtained according to the acquisition of 2 subparameters judge that air-conditioning A leaks
Fluorine.
Step 206: judging whether the third operating parameter obtained according to each time and third environmental parameter determine air-conditioning hair
Otherwise raw leakage fluorine terminates current process if so, executing step 207.
In an embodiment of the invention, the judging result judged each time in judgment step 205 whether be, if
It is correspondingly to execute step 207, otherwise terminate current process.
