More specifically, when air-conditioner is in refrigeration operational state, be in temperature ramp de due to outdoor environment temperature and be in temperature decline process, the outdoor environment temperature circle point of the operational taps of outdoor fan is different, so outdoor environment temperature is in temperature ramp de and is in temperature decline process, threshold interval corresponding separately also can be different, therefore, can first judge the outdoor environment temperature detected, first can obtain outdoor environment temperature corresponding when controlling the Last operational taps of outdoor fan, by current detection to the outdoor environment temperature outdoor environment temperature corresponding with during this Last operational taps of control outdoor fan carry out size and compare, to judge that this outdoor environment temperature is in outdoor environment temperature uphill process, still outdoor environment temperature decline process is in, if current detection is large to outdoor environment temperature, then illustrate that outdoor environment temperature is in outdoor environment temperature uphill process, then can determine the threshold interval of its correspondence from refrigeration ascending threshold interval according to this outdoor environment temperature, and according to the operational taps of this threshold interval determination outdoor fan determined, if current detection is little to outdoor environment temperature, then illustrate that outdoor environment temperature is in outdoor environment temperature decline process, then can determine the threshold interval of its correspondence according to this outdoor environment temperature from refrigeration falling-threshold value interval, and according to the operational taps of this threshold value determination outdoor fan determined.
Such as, when determining that according to outdoor environment temperature corresponding refrigeration ascending threshold interval is the first refrigeration ascending threshold interval, then can determine that the operational taps of outdoor fan is the first operational taps; When determining that according to outdoor environment temperature corresponding refrigeration ascending threshold interval is the second refrigeration ascending threshold interval, then can determine that the operational taps of outdoor fan is the second operational taps; When determining that according to outdoor environment temperature corresponding refrigeration ascending threshold interval is the 3rd refrigeration ascending threshold interval, then can determine that the operational taps of outdoor fan is the 3rd operational taps; When determining that according to outdoor environment temperature corresponding refrigeration ascending threshold interval is the 4th refrigeration ascending threshold interval, then can determine that the operational taps of outdoor fan is the 4th operational taps; When determining that according to outdoor environment temperature corresponding refrigeration ascending threshold interval is the 5th refrigeration ascending threshold interval, then can determine that the operational taps of outdoor fan is the 5th operational taps; When determining that according to outdoor environment temperature corresponding refrigeration ascending threshold interval is the 6th refrigeration ascending threshold interval, then can determine that the operational taps of outdoor fan is the 6th operational taps.
And for example, when determining that according to outdoor environment temperature corresponding refrigeration falling-threshold value interval is the first refrigeration falling-threshold value interval, then can determine that the operational taps of outdoor fan is the first operational taps; When determining that according to outdoor environment temperature corresponding refrigeration falling-threshold value interval is the second refrigeration falling-threshold value interval, then can determine that the operational taps of outdoor fan is the second operational taps; When determining that according to outdoor environment temperature corresponding refrigeration falling-threshold value interval is the 3rd refrigeration falling-threshold value interval, then can determine that the operational taps of outdoor fan is the 3rd operational taps; When determining that according to outdoor environment temperature corresponding refrigeration falling-threshold value interval is the 4th refrigeration falling-threshold value interval, then can determine that the operational taps of outdoor fan is the 4th operational taps; When determining that according to outdoor environment temperature corresponding refrigeration falling-threshold value interval is the 5th refrigeration falling-threshold value interval, then can determine that the operational taps of outdoor fan is the 5th operational taps; When determining that according to outdoor environment temperature corresponding refrigeration falling-threshold value interval is the 6th refrigeration falling-threshold value interval, then can determine that the operational taps of outdoor fan is the 6th operational taps.

Further, because the operational taps of outdoor fan interval and corresponding from temperature threshold corresponding when being in refrigeration operational state when air-conditioner is in heating operation state is different, therefore, when air-conditioner is in heating operation state, according to heating temperature threshold interval, the operational taps of outdoor fan is controlled accordingly.Particularly, in one embodiment of the invention, this control method also can comprise: when air-conditioner is in heating operation state, obtains outdoor environment temperature corresponding when controlling the Last operational taps of outdoor fan; Judge whether outdoor environment temperature is greater than outdoor environment temperature corresponding when controlling the Last operational taps of outdoor fan; If so, then determine corresponding to heat ascending threshold interval according to outdoor environment temperature, and according to heating ascending threshold interval and determine the operational taps of outdoor fan; If not, then determine corresponding to heat falling-threshold value interval according to outdoor environment temperature, and according to heating falling-threshold value interval and determine the operational taps of outdoor fan.Wherein, in an embodiment of the present invention, heat ascending threshold interval and can comprise first and heat ascending threshold interval to the 6th, heat falling-threshold value interval and first can heat falling-threshold value interval to the 6th.
More specifically, when air-conditioner is in heating operation state, be in temperature ramp de due to outdoor environment temperature and be in temperature decline process, the outdoor environment temperature circle point of the operational taps of outdoor fan is different, so outdoor environment temperature is in temperature ramp de and is in temperature decline process, threshold interval corresponding separately also can be different, therefore, can first judge the outdoor environment temperature detected, first can obtain outdoor environment temperature corresponding when controlling the Last operational taps of outdoor fan, by current detection to the outdoor environment temperature outdoor environment temperature corresponding with during this Last operational taps of control outdoor fan carry out size and compare, to judge that this outdoor environment temperature is in outdoor environment temperature uphill process, still outdoor environment temperature decline process is in, if current detection is large to outdoor environment temperature, then illustrate that outdoor environment temperature is in outdoor environment temperature uphill process, then can according to this outdoor environment temperature from heating the threshold interval determining its correspondence ascending threshold interval, and according to the operational taps of this threshold interval determination outdoor fan determined, if current detection is little to outdoor environment temperature, then illustrate that outdoor environment temperature is in outdoor environment temperature decline process, then can according to this outdoor environment temperature from heating the threshold interval determining its correspondence falling-threshold value interval, and according to the operational taps of this threshold value determination outdoor fan determined.
Such as, when determine according to outdoor environment temperature corresponding heat ascending threshold interval be first heat ascending threshold interval time, then can determine that the operational taps of outdoor fan is the 6th operational taps; When determine according to outdoor environment temperature corresponding heat ascending threshold interval be second heat ascending threshold interval time, then can determine that the operational taps of outdoor fan is the 5th operational taps; When determine according to outdoor environment temperature corresponding heat ascending threshold interval be the 3rd heat ascending threshold interval time, then can determine that the operational taps of outdoor fan is the 4th operational taps; When determine according to outdoor environment temperature corresponding heat ascending threshold interval be the 4th heat ascending threshold interval time, then can determine that the operational taps of outdoor fan is the 3rd operational taps; When determine according to outdoor environment temperature corresponding heat ascending threshold interval be the 5th heat ascending threshold interval time, then can determine that the operational taps of outdoor fan is the second operational taps; When determine according to outdoor environment temperature corresponding heat ascending threshold interval be the 6th heat ascending threshold interval time, then can determine that the operational taps of outdoor fan is the first operational taps.
