Detailed description of the invention
For the scheme in the present invention is clearly described, preferred embodiment is given below and is described with reference to the accompanying drawings.With
Under illustrative in nature on be merely exemplary and be not intended to limit the application of the disclosure or purposes.It should be appreciated that
In whole accompanying drawings, corresponding reference represents identical or corresponding parts and feature.
Flow chart as shown in Figure 1, the present invention relates to a kind of method maintaining air-conditioning amount, and step includes: obtain sky
Wind deflector when running with set position is adjusted to carry out maintaining during air-supply work the inflection point of fixed angle；Under set position,
Current air output when being in benchmark air output during reference position by wind deflector and be in inflection point, calculates and determines air-supply
Amount difference；Determine the speed considerations value of blower fan according to air output difference, and blower fan is compensated regulation, by readjusting wind
The rotating speed of machine so that actual air output when wind deflector is in inflection point is close with benchmark air output, thus reaches both to adjust
Wind direction, the purpose that maintenance air output is constant again.
The reference position that the present invention is selected is: be issued to the wind deflector position of maximum air supply rate at set position, meanwhile,
Air output on the basis of maximum air supply rate under this set position.
Wind deflector be in reference position constant in the case of, air-conditioner in order to realize refrigeration or heat under state with not
With air quantity air-supply, be mainly controlled by enabling different gear, the corresponding fixed blower fan initial speed of each gear,
General, it is the maximum air supply rate under this set position with the air output of the blower fan of initial speed operation.Therefore the present invention
Speed considerations is i.e. the compensation regulation carried out on the basis of the blower fan initial speed of a certain gear.
In an embodiment of the invention, as in figure 2 it is shown, under a certain preset gear, select the inclined of wind deflector at five
Indexing is put, and the most often place's inflection point is as shown in table 1 below with the corresponding relation of rotation speed of fan:
Table 1
In table, position on the basis of guide plate position 3, in the case of running with initial speed N, its air output has reached maximum and has sent
Air quantity, therefore the offset of its rotation speed of fan is 0；
According to the difference of air-conditioner different type of machines, initial speed N value corresponding under different gears is true according to practical situation
Fixed.
General, the reference position of wind deflector is that wind deflector levels off to the position of air outlet middle or almost parallel
In the position of main air-out direction, as a example by the wind deflector pattern spun upside down, wind deflector under the drive of motor may upwards or
Downward carries out bilateral deflection rotation, it is therefore desirable to obtaining the concrete inflection point of wind deflector, main mode includes: (1) exists
Wind deflector position arranges induction apparatus, is compared with predeterminated position the wind deflector position detected in real time, determines actual deflection position

It is possible not only to be turned to a certain inflection point by reference position, it is also possible to be adjusted between two inflection points, accordingly
Rotation speed of fan also changes.Therefore the inflection point in the present invention at least includes the first inflection point and the second inflection point,
And both do not overlap with reference position；Under set position, wind deflector is deflected to deflect at another by a wherein inflection point
During position, first when being in benchmark air output during reference position by wind deflector, be in the first inflection point is currently blown
Measure and be in the second current air output during the second inflection point, calculate and determine air output difference,；True according to air output difference
The speed considerations difference of subduing the wind syndrome machine, and as the second speed considerations value, blower fan is compensated regulation using speed considerations difference；Tool
During the calculating of body, can first calculate the actual rotation speed of fan corresponding to inflection point at two, further according to two actual blower fans
Rotating speed determines the speed considerations difference between two inflection points, the first inflection point, after turning to the second inflection point, lead
Aerofoil can closer or far from reference position, therefore speed considerations difference may be negative value or on the occasion of, rotation speed of fan subtracts accordingly
Little or increase, determine according to actual inflection point.
