As shown in fig. 1, the control method of the air conditioner includes: step 110 and step 120.
And 110, acquiring the current air outlet pressure of a centrifugal fan of the air conditioner.
The air conditioner is set to operate according to target air pressure, the target air pressure is the air pressure controlled by the constant air pressure of the air conditioner, and in actual execution, the target air pressure can be an air pressure value set by a user or a pre-stored air pressure value in the air conditioner.
In this embodiment, the air conditioner is controlled to operate at the target wind pressure, that is, the operation mode of the air conditioner is the mode of constant wind pressure control.
It can be understood that the air pressure of the air conditioner is mainly provided by the centrifugal fan, and the air pressure output by the air conditioner is related to the air pressure at the air outlet of the centrifugal fan.
Wherein, centrifugal fan's air outlet pressure is the parameter that is used for the wind pressure of the air outlet department of sign centrifugal fan.
In practical implementation, a pressure sensor may be disposed at the air outlet of the centrifugal fan to measure the air outlet pressure.
In this step, the air conditioner operates in a constant air pressure control mode of target air pressure to obtain a current air outlet pressure of the centrifugal fan, wherein the current air outlet pressure refers to the current air outlet pressure of the centrifugal fan.
And 120, adjusting working parameters of the centrifugal fan based on the current air outlet pressure and the target air outlet pressure.
Wherein the target outlet pressure is determined based on the target wind pressure.
It should be noted that, a centrifugal fan of an air conditioner is an important component for controlling the air supply pressure, and for a set target air pressure, when the centrifugal fan realizes constant output of the target air pressure, the corresponding air outlet pressure is constant, that is, the target air outlet pressure can be determined according to the target air pressure.
In this embodiment, the difference between the current outlet pressure and the target outlet pressure is determined by comparing the current outlet pressure with the target outlet pressure, and the operating parameter of the centrifugal fan is adjusted, so that the current outlet pressure at which the centrifugal fan operates can be the same as the target outlet pressure, and the air conditioner can realize the constant air pressure control of the target air pressure.

It can be understood that the current air outlet pressure of the centrifugal fan can be continuously obtained, the current air outlet pressure is compared with the target air outlet pressure in real time, and when the difference value between the current air outlet pressure and the target air outlet pressure is within the range of the target difference value, the adjustment of the working parameters of the centrifugal fan is stopped, so that the constant air pressure control of the air conditioner is realized.
In some embodiments, the step 120 of adjusting an operating parameter of the centrifugal fan based on the current outlet pressure and the target outlet pressure may include:
and under the condition that the difference value between the current air outlet pressure and the target air outlet pressure exceeds the target difference value range and the current air outlet pressure is smaller than the target air outlet pressure, adjusting the working parameters of the centrifugal fan to be second working parameters, wherein the second working parameters are larger than the current working parameters of the centrifugal fan.
In this embodiment, the difference between the current outlet pressure and the target outlet pressure exceeds the target difference range, and the current operating parameter of the centrifugal fan needs to be adjusted.
And adjusting the working parameter of the centrifugal fan to be a second working parameter, wherein the current air outlet pressure is less than the target air outlet pressure, the output power of the air supply of the centrifugal fan needs to be improved, and the second working parameter is greater than the current working parameter of the centrifugal fan.
For example, the target difference range may be (-5, + 5).
The difference value between the current air outlet pressure and the target air outlet pressure is larger than 5, the target difference value range is exceeded, the current air outlet pressure is larger than the target air outlet pressure, and at least one of the working voltage, the working current and the working rotating speed of the centrifugal fan can be reduced.
And adjusting the working rotating speed of the centrifugal fan from the current working rotating speed to a second working rotating speed, wherein the second working rotating speed is greater than the current working rotating speed.
It can be understood that the current air outlet pressure of the centrifugal fan can be continuously obtained, the current air outlet pressure is compared with the target air outlet pressure in real time, and when the difference value between the current air outlet pressure and the target air outlet pressure is within the target difference value range, the adjustment of the working parameters of the centrifugal fan is stopped, so that the constant air pressure control of the air conditioner is realized.
In the following, a centrifugal fan is taken as an EC fan, and a specific embodiment is described.
As shown in fig. 2, the air pressure of the air conditioning unit is set, and the set partial pressure P1 (i.e., the target air pressure) is stored in the controller.
The pressure sensor arranged at the air outlet of the EC fan detects the air outlet pressure P2 (namely the current air outlet pressure) of the actual operation of the EC fan.
When delta P = P2-P1= +/-5 Pa, the running pressure of the EC fan meets the set wind pressure running range of the unit, and the working voltage, the working current or the working rotating speed of the EC fan maintains the current output.
When the delta P = P2-P1 is larger than 5Pa, the running pressure of the EC fan is higher than the set wind pressure of the unit, the output of the working voltage, the working current or the working rotating speed of the EC fan is reduced, the pressure P2 of the actual running of the outlet wind of the unit is collected again after the working parameters of the EC fan are adjusted, when the delta P = P2-P1 is not larger than +/-5 Pa, the running pressure of the EC fan meets the set wind pressure running range of the unit, and the working voltage, the working current or the working rotating speed of the EC fan maintains the current output.
When the delta P = P2-P1 is less than 5Pa, the running pressure of the EC fan is lower than the set wind pressure of the unit, the working voltage, the working current or the working rotating speed output of the EC fan is increased, the pressure P2 of the actual running of the air outlet of the unit is collected again after the working parameters of the EC fan are adjusted, when the delta P = P2-P1 is less than +/-5 Pa, the running pressure of the EC fan meets the set wind pressure running range of the unit, and the working voltage, the working current or the working rotating speed of the EC fan maintains the current output.
