Detailed description of the invention
In the following detailed description, a large amount of specific detail is proposed, in order to provide thorough understanding of the present invention.But,
Even if it will be understood by those within the art that and not having these specific detail also can implement the present invention.In other cases, the most in detail
The well-known method of thin description, process, assembly and circuit, in order to avoid affecting the understanding of the present invention.
In conjunction with shown in Figure 1, according to embodiments of the invention, air conditioner supplying natural wind rotation speed of fan control method includes: obtain
Take the air-conditioner air outlet wind speed of current slot；Air-conditioner air outlet wind speed according to current slot and the nature of next time period
Wind characteristic parameter determines the air-conditioner air outlet wind speed of next time period；Air-conditioner air outlet wind speed according to current slot and under
Rotation speed of fan is adjusted by the air-conditioner air outlet wind speed of individual time period.
The air conditioner supplying natural wind rotation speed of fan control method of the present invention, it is possible to require to adjust in real time according to natural wind characteristic curve
Rotation speed of fan so that air-conditioner air outlet can continuously blow out natural wind, simultaneously because this natural wind derives from natural wind
Characteristic curve, rather than be extraneous natural wind, therefore can ensure that air-conditioner goes out by setting suitable natural wind characteristic curve
The air-out in air port remains stable natural wind state, not by ectocine, and parameter testing difficulty and dissimilar nature
The acquisition difficulty of wind is less, and natural wind air-supply fluctuations in wind speed feature does not repeats, and fluctuations in wind speed is steady, and real-time is good, required calculating
Measuring little, processing speed is fast, can be effectively improved the comfortableness of human body under natural wind air-out state.
