Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, wind pipe type indoor set static pressure auto-adjustment control method and system of the present invention are further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment one
As shown in Figure 1 and Figure 2, the embodiment of the present invention provides a kind of wind pipe type indoor set static pressure auto-adjustment control method, comprises the following steps:
S100, the direct current generator controlling indoor set after the start that powers on runs by the corresponding rotation speed of fan of default static pressure;
S200, carries out the detection of running current value after described direct current generator runs the very first time;
S300, judges whether the running current value comparing detection falls within the scope of the corresponding target current of default static pressure;
S400, according to judging that the result compared carries out the control of static pressure stable regulation.
The method by detect running current value and target current scope carry out automatically adjusting to the rotating speed of comparison direct current generator, make wind pipe type indoor set install and use in process the output remaining permanent wind amount, meet the requirement of user's comfort.Very first time t1 is wherein 1min.
As a kind of embodiment, described according to judging that the result compared carries out the control of static pressure stable regulation, comprise the steps:
S410, if running current value falls within the scope of the corresponding target current of default static pressure, direct current generator keeps presetting the corresponding rotating speed of static pressure;
S420, if running current value does not fall within the scope of the corresponding target current of default static pressure, direct current generator carries out corresponding rotational speed regulation.
When after the start that powers on, if when the running current value detected is within the scope of the corresponding target current of default static pressure, direct current generator then keeps this rotating speed constant, if when not falling within the scope of the corresponding target current of default static pressure, the rotating speed of direct current generator is heightened accordingly or turns down.Wherein, target current scope comprises the minimum of a value of this target current, does not comprise the maximum of this target current scope.
As a kind of embodiment, if described running current value does not fall within the scope of the corresponding target current of default static pressure, direct current generator carries out corresponding rotational speed regulation, comprises the steps:
S421, if running current value is more than or equal to the maximum of target current scope, control direct current generator to run by presetting the corresponding rotating speed of next stage static pressure corresponding to static pressure, before running the laggard trade of the second time, running current value detects, and judges whether to fall within the scope of the corresponding target current of current static pressure;
