Detailed description of the invention
Below by specific embodiment and combine accompanying drawing to describe the present invention in detail.
A kind of method of adjustment of the rotation speed of fan of air-conditioning, including:
Detect the current static pressure of described air-conditioning；
Under the conditions of each the different air quantity pre-build, in the relation of static pressure and rotation speed of fan value,
Set air quantity and described current static pressure according to current, find the rotation speed of fan value of correspondence；
Control blower fan to operate according to the described rotation speed of fan value found.
Control described air-conditioning to run according to mode standard, and measure the relation of static pressure and rotation speed of fan.
Described current static pressure is calculated according to the present current value of described compressor electric motor, and formula is:
Static pressure=(motor current value-1)/10；
Wherein, error amount is ± 0.1.
Described static pressure with the reduction formula of described rotation speed of fan is:
Rotation speed of fan=static pressure coefficient × static pressure.
Described static pressure coefficient is calculated as follows:
Static pressure coefficient=K*2* π * R*L, wherein, R is the radius of airduct pipeline, and L is airduct pipeline
Length, K is constant.
Described Changshu K is in the range of 1-5.5.
Described air conditioning exhausting amount is inversely proportional to described static pressure.
When air-conditioning rotating speed one timing, static pressure increases, and the air output of air-conditioning declines, air-conditioning power increases,
Such as following table:
| Test static pressure | Revolution 960 | Air quantity | Power |
| 0.5 | 960 | 13659 | 1320 |
| 9.9 | 960 | 13542 | 1320 |
| 20.2 | 960 | 13347 | 1390 |
| 30 | 960 | 12979 | 1350 |
| 40.2 | 960 | 12653 | 1420 |
| 50 | 960 | 12359 | 1450 |
| 60.1 | 960 | 12092 | 1480 |
| 70 | 960 | 11754 | 1550 |

| 99.3 | 960 | 10669 | 1620 |
| 109.7 | 960 | 10314 | 1720 |
Therefore, it is possible to by judging at air-conditioner air outlet that static pressure regulates the air output of air-conditioning, and static pressure
It is not easy measured, and at air-conditioner air outlet, the motor current value of static pressure and air-conditioning has a following relationship:
| Test static pressure | Revolution 960 | Electric current |
| 0.5 | 955 | 2.79 |
| 9.9 | 960 | 2.76 |
| 20.2 | 960 | 2.9 |
| 30 | 960 | 2.95 |
| 40.2 | 960 | 2.99 |
| 50 | 960 | 3.02 |
| 60.1 | 960 | 3.07 |

| 90 | 960 | 3.24 |
| 99.3 | 960 | 3.35 |
| 109.7 | 960 | 3.54 |
That is, under conditions of keeping rotating speed constant, static pressure and described motor at described air-conditioner air outlet
Current value is directly proportional,
Shown static pressure as shown in Figure 3 and the graph of a relation of current value, its computing formula is:
Static pressure=(motor current value-1)/10；
That is, when obtaining current value and changing, static pressure also can change, and represents air output and sends out
Changing, for keeping air output certain, then needs to increase rotation speed of fan, such as following table:
The air quantity contrast of rotating speed is regulated under table-difference static pressure
On the premise of ensureing that air output is certain, according to the change of electric current, the electric current after selecting and changing
Corresponding rotation speed of fan, and make blower fan be adjusted, reach to ensure the purpose of air output.
It is only the preferred embodiment of the present invention by the above, it is noted that for the art
Those of ordinary skill for, under the premise without departing from the principles of the invention, it is also possible to make some changing
Entering and retouch, these improvements and modifications also should be regarded as protection scope of the present invention.
