Disclosed is a self-adaptive static pressure adjusting method of an air duct machine, the method comprising: subdividing static pressure in an air duct into several static pressure sections i; selecting a static pressure section i and a static pressure section i+1, and respectively detecting air gears at the static pressure section i and the static pressure section i+1, fan rotating speeds Ri and Ri+1 under the air gears, and corresponding actual operating current values Ii and Ii+1, judging whether Ii and Ii+1 are within a normal current range, and determining a final static pressure section according to a judgement result and pre-set conditions. Further provided is a self-adaptive static pressure adjusting device of an air duct machine and an air duct machine having the self-adaptive static pressure adjusting device of an air duct machine. By means of the adjusting method, an air duct machine can automatically select and determine a static pressure section according to the actual installation environment, find an optimal static pressure section for the operation of the air duct machine, and have high precision. |
