Coil temperature drop-out value be less than preset temperature drop-out value, the preset temperature drop-out value be less than above-mentioned normal temperature drop-out value.
Outdoor fan control method disclosed in the present embodiment, is more than under standard in the coil temperature drop-out value of outdoor heat exchanger
During depreciation, the rotating speed of outdoor fan is can adjust, frosting is delayed with the heat exchange amount for increasing outdoor heat exchanger, while with outdoor heat exchange
The temperature drop increase standard drop-out value of device, to avoid the rotating speed of outdoor fan is too fast from reaching maximum, this programme by up to
The rotating speed of outdoor fan is repeatedly adjusted before to defrosting condition to delay outdoor heat exchanger frosting, reduces the air-conditioning in adverse circumstances
The defrosting number of times of device, improves heating effect.
Further, outdoor fan control method second embodiment of the present invention is proposed based on first embodiment, in this implementation
In example, outdoor fan control method also includes：
When air conditioner meets defrost condition, normal temperature drop-out value is reset into default normal temperature drop-out value；
Or, when air conditioner enters heating mode, normal temperature drop-out value is reset into default normal temperature and declined
Value.
In scheme disclosed in the present embodiment, decline after defrost pattern is entered or into replacement normal temperature after heating mode
Value so that reenter when heating that standard temperature drop value will not be too high, but as the regulation to rotating speed is constantly raised, improve
The accuracy controlled outdoor fan of air conditioner, while there is provided heating effect to the regulation increased frequency of outdoor fan.
Further, reference picture 3, propose that outdoor fan control method the 3rd of the present invention is real based on first or second embodiments
Example is applied, in the present embodiment, outdoor fan control method also includes：
Step S60, when air conditioner heat-production is run, obtains the operation duration of air conditioner；
When the operation duration of air conditioner is more than preset duration, step S10 is performed, that is, obtains the coil pipe temperature of outdoor heat exchanger
Degree.
When entering heating mode due to air conditioner, it may just carry out defrosting or just open, now outdoor heat exchanger
Temperature is higher, using the temperature as initial temperature may cause calculating obtain at a temperature of depreciation it is excessive, then can be in air conditioner system
When outdoor heat exchanger temperature is more normal after heat operation a period of time, the coil temperature of outdoor heat exchanger is obtained, to cause to room
The volume control of outer blower fan is more accurate.
Further, propose that outdoor fan control method the 4th of the present invention is implemented based on the first to the 3rd any embodiment
Example, in the present embodiment, step S40 includes：
Obtain incremental speed；
The rotating speed of outdoor fan is adjusted according to the incremental speed of acquisition.
It is understood that further to improve the accuracy controlled outdoor fan, can increase according to the rotating speed of acquisition
After the rotating speed of amount adjustment outdoor fan, incremental speed is updated, the incremental speed after renewal is more than the incremental speed before updating, and makes
Obtain rotating speed quickly to increase, to avoid frosting.The incremental speed can be preset ratio value, and such as preset ratio value is 10%, and is worked as
Preceding rotating speed is 50, then the rotating speed after adjusting is 50*110%=55, and the default incremental speed is alternatively default incremental speed
Value, such as default incremental speed value is 10, and current rotating speed is 50, then the rotating speed after adjusting is 60.
During due to adjusting rotating speed according to default incremental speed, obtained rotating speed is calculated according to preset increments and is likely larger than room
Rotating speed, now can directly be adjusted to maximum (top) speed, that is, obtain the step of current incremental speed by the maximum (top) speed that outer blower fan allows
After rapid, step S40 also includes：
Judge to increase the maximum (top) speed whether rotating speed after adjustment is more than outdoor fan according to current rotating speed；
