Accompanying drawing explanation
Fig. 1 is that the control method flow process principle of air conditioner room unit rotation speed of the fan of the present invention is always schemed.
Fig. 2 is the sub-step process principle figure of step S2 of the present invention.
Below by the drawings and specific embodiments, the invention will be further described:
The specific embodiment
Fig. 1 and 2 is depicted as the control flow chart of the inventive method, now in conjunction with Fig. 1 and 2, the control method of air conditioner room unit rotation speed of the fan of the present invention is described in detail, and control method of the present invention comprises the following steps:
Step S1: judged whether rise of rotational speed alteration command, if so, entered step S2, if not, kept the existing rotating speed of indoor machine fan.
Step S2: analyze air conditioner function and set and judge whether to need rotating speed rising, if so, enter step S3, if not, indoor machine fan rotating speed is climbed to rotating speed of target by existing normal mode.
Step S3: calculate speed discrepancy △ R=rotating speed of target-current rotating speed, contrast speed discrepancy △ R determines the rotation speed of the fan rising rate of change t in corresponding scope:
1) when △ R < 100rpm, indoor machine fan rotating speed is climbed to rotating speed of target by existing normal mode, i.e. the rotation speed of the fan rising rate of change of the existing normal mode of t=;
