(system high pressure scope is 26 ± 5kgf to this zone of reasonableness, it is preferable that 26 ± 3kgf；System low-voltage scope is 7 ± 2kgf, preferably
Ground, 7 ± 1kgf；The exhaust temperature ranges of compressor is 70 ± 15 DEG C, it is preferable that 70 ± 10 DEG C) in, it is possible to determine that system is run
State is normal；
2, secondly combine judge indoor set heat exchange situation according to inlet temperature and the leaving air temp of indoor set: filtering dress
Putting pollution condition lighter, it is not necessary to during cleaning, defecator is relatively light for the impact of indoor set air quantity, and heat exchange efficiency is higher, goes out
The difference of air temperature and inlet temperature is in zone of reasonableness, and this zone of reasonableness is assumed to 18 ± 7 DEG C, preferably 18 ± 3 DEG C；As
Really defecator pollution condition is heavier, and when needing cleaning, defecator is more obvious for the impact of indoor set air quantity, and heat exchange is imitated
Rate declines, and leaving air temp raises, and therefore when the difference of leaving air temp and inlet temperature increases to more than 28 DEG C, then illustrates to filter
Device is dirtier；
3, then need to combine electronic expansion valve of indoor unit aperture to judge:, indoor set heat exchange situation clean at defecator
Time good, electric expansion valve can play the effect suitably controlling heat transferring medium flow, the aperture of electric expansion valve 250～
350 pulses, if defecator damage ratio is more serious, when indoor set heat exchange reduces, indoor-unit cooling-medium amount increase in demand, electronics is swollen
Swollen valve can be held big to bigger aperture；
4 if the system detects that properly functioning air-conditioner system meets condition 2 and condition 3 simultaneously, then judge to filter dress
Put damage ratio more serious, i.e. report to the police, then clear up defecator.
Technique scheme by the ruuning situation of system, the inlet temperature of indoor set and the difference of leaving air temp and
The detection of the aperture of electric expansion valve, just draws the conclusion whether clearing up defecator after more accurately comprehensively judging, aobvious
So, this technical scheme improves the degree of accuracy that the cleaning of defecator is reminded.
Further in technical scheme, in step S11, if air conditioning system is run abnormal, then enter following steps:
S13, send system maintenance alerting signal.
That is, when system is run abnormal, i.e. parts in-problem in system are keeped in repair, to ensure that system is just
Often run.
In order to better ensure that the heat exchange of air-conditioner, in above-mentioned steps S14, when inlet temperature and the leaving air temp of indoor set
Difference less than or equal to the temperature difference preset value time, then return step S12, more preferably, can return to step S11.Specifically, above-mentioned bar
After part meets, corresponding steps can be returned after predetermined period.Obviously, this technical scheme can be circulated inspection to air-conditioner system
Survey, reach above-mentioned purpose with this.
In like manner, in step S3, when heating, the aperture of electric expansion valve is less than or equal to the first aperture preset value, or system
When the aperture of electric expansion valve is more than or equal to the second aperture preset value time cold, returns step S12, more preferably, can return to step
S11。
