If meeting, according to the current operating condition of the air conditioner according to processing strategy execution institute corresponding with the operating condition
State cleaning procedure.
5. clean method according to claim 4, it is characterised in that in the current operating condition of the air conditioner to heat
In the case of operating mode, the trigger condition also at least includes one below:Whether outdoor unit produces frost or air conditioner
It is no to be performed power-off operation;
If so, the then cleaning procedure according to processing strategy execution of the air conditioner under heating condition.
6. clean method according to claim 5, it is characterised in that when the surface temperature of outdoor heat exchanger meet Tc≤
Tw- Δs t and Tc<During 0 DEG C of certain time, judge that the outdoor unit produces the frost;
Wherein, Tc is outdoor heat exchanger outlet temperature, and Tw is that outdoor environment temperature, Δ t are offset set in advance, between 5
Between~10 DEG C.
7. clean method according to claim 5, it is characterised in that it is described according to the air conditioner under heating condition
Cleaning procedure described in handling strategy execution, is specifically included:
The air conditioner is switched into cooling condition, using the heat exchanger in air conditioner by the water vapor condensation in air conditioner into liquid
State water, will be attached to the dirt removal on the surface of the heat exchanger.
8. clean method according to claim 4, it is characterised in that according to processing of the air conditioner under cooling condition
Cleaning procedure described in strategy execution, is specifically included:
Perform following at least one times operate:
Perform the cleaning procedure operation first time period, then normal refrigerating operaton second time period.
9. a kind of adjusted based on wind speed collects the device that condensed water cleans air conditioner, based on using the heat exchanger in air conditioner by sky
Adjust the water vapor condensation in device into aqueous water, will be attached to the dirt removal on the surface of the heat exchanger, including:
Judge module, the trigger condition of the cleaning procedure is performed for judging whether the air conditioner meets;
Cleaning module, for when meeting the trigger condition, according to the current operating condition of the air conditioner according to the fortune
Cleaning procedure described in the corresponding processing strategy execution of row operating mode;Wherein described cleaning module includes:
Parsing module, including:
First analyzing sub-module, according to the current environment temperature of the air conditioner and ambient humidity, is analyzed under current environment
Dew-point temperature;With
Second analyzing sub-module, for the dew-point temperature to analyze, determine the heat exchanger be used for condense expectation temperature
Degree;
Adjustment module, by adjusting the rotating speed of the blower fan in the air conditioner and/or the working frequency of compressor, by the heat exchange
The temperature adjustment of device simultaneously maintains the preferred temperature;And second analyzing sub-module determines the expectation according to equation below
Temperature:
Teva=t- Δs t
Wherein, the Teva is the preferred temperature of the heat exchanger, and t is dew-point temperature, and Δ t is the phase of dew-point temperature and heat exchanger
Hope the temperature difference.
