10. device according to claim 9, it is characterised in that the collecting unit also includes：
4th collection subelement, for gathering interior of the air conditioning multi-couple machine under the heating mode by the temperature-sensitive bag
Environment temperature and the second inner tube temperature, wherein, the operating temperature includes the indoor environment temperature and the second inner tube temperature
Degree.
11. devices according to claim 10, it is characterised in that
The collecting unit also includes：5th collection subelement, for the real time execution frequency for gathering the compressor, the pressure
The current operation power of contracting machine and the compressor lack fluorine and judge power radix；
The processing unit also includes：Fourth process subelement, if for the second inner tube temperature and the indoor environment temperature
The difference of degree is not more than the 6th predetermined threshold value, and the current operation power of the running frequency of the compressor, the compressor and
The compressor lacks fluorine and judges that power radix meets preset formula, it is determined that the scarce fluorine testing result indicates the air conditioning multi-couple
Machine lacks fluorine under the heating mode,
Wherein, the preset formula is：G1≤G0+F1* Q, the F1It is the real time execution frequency, the G1It is the compressor
Current operation power, the G0Judge that power radix and Q are predetermined coefficient for compressor lacks fluorine.
12. device according to any one of claim 7 to 11, it is characterised in that described device also includes：
Changing unit, for changing the initial launch frequency of the air conditioning multi-couple machine, and returns to execution by the air conditioning multi-couple
The temperature-sensitive bag of machine gathers the operating temperature of the air conditioning multi-couple machine, until the number of times for changing the initial launch frequency meets default
Number of times.
