Embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of rotating speed of air conditioner fan control method, and reference picture 1, in one embodiment, the air-conditioning draught fan turn
Speed control method includes：
Step S10, under cooling operation mode, obtains the leaving air temp and indoor environment temperature of indoor set；
Step S20, calculates the interior room environment temperature and the difference of the leaving air temp；
Step S30, judges that the preset temperature belonging to the difference is interval；
Step S40, turn of the blower fan of indoor set is adjusted according to the interval corresponding rotation speed of fan variable quantity of the preset temperature
Speed；The blower fan variable quantity is the reduction amount relative to preset initial rotation speed of fan.
When the rotating speed of air conditioner fan control method that the present embodiment is provided is mainly used in air-conditioning system refrigerating operaton, to blower fan
The control of rotating speed.The interval quantity of above-mentioned preset temperature and scope can be configured according to actual needs, it is possible to understand that
It is that above-mentioned preset temperature interval is continuous interval, i.e., the interval lower limit of a upper preset temperature is interval for next preset temperature
Lower limit.In the present embodiment, it is preferable that above-mentioned preset temperature interval can be with three, with three preset temperature in following examples
It is explained in detail exemplified by degree is interval.Specifically, above-mentioned preset temperature interval includes the first temperature more than the first preset temperature
Interval, it is less than or equal to the first preset temperature and interval and pre- less than second more than or equal to the second temperature of the second preset temperature
If the 3rd temperature range of temperature；First preset temperature is more than second preset temperature；The second temperature interval is right
The rotation speed of fan variable quantity answered is less than the corresponding rotation speed of fan variable quantity of the first temperature range, and more than the 3rd temperature range correspondence
Rotation speed of fan variable quantity.In the interval corresponding rotation speed of fan variable quantity of each preset temperature, e.g., above-mentioned first temperature range
The first rotation speed of fan variable quantity of correspondence, above-mentioned second temperature interval the second rotation speed of fan variable quantity of correspondence, the 3rd temperature range pair
Answer the 3rd rotation speed of fan variable quantity.Above-mentioned first rotation speed of fan variable quantity, the second rotation speed of fan variable quantity and the 3rd rotation speed of fan
The big I of variable quantity is configured according to actual needs, does not do further limiting herein.
