In the embodiment, the target rotation speed gear of the centrifugal fan is determined according to the first temperature value and the target temperature value, the centrifugal fan is controlled to rotate according to the target rotation speed gear, the temperature value between the electric heater and the evaporator of the air conditioner can reach the target temperature value, and the constant-temperature and constant-humidity control of the air conditioner is realized.
In a practical implementation, the centrifugal fan comprises a plurality of rotational speed steps, each rotational speed step having a corresponding rotational speed.
The mapping relationship between the gear position and the rotation speed can be shown in table 2.
In actual execution, the target rotating speed gear of the centrifugal fan of the air conditioner is determined to be 5 gears based on the first temperature value and the target temperature value, and the centrifugal fan is controlled to rotate according to the rotating speed of 270 r/min.
It should be noted that, through the adjustment of the rotational speed of the centrifugal fan, the air volume on the evaporation side of the air conditioner can be controlled, so as to adjust the temperature between the evaporator and the electric heater, and through the gear adjustment of the centrifugal fan, the temperature between the evaporator and the electric heater can be properly adjusted under different environmental temperatures, thereby achieving the purpose of dehumidification.
According to the control method of the centrifugal fan of the air conditioner, the rotating speed gear of the centrifugal fan is adjusted through the first temperature value and the target temperature value between the evaporator and the electric heater, so that the temperature between the evaporator and the electric heater is maintained at the target value, the control method is suitable for the air conditioner of a fixed-frequency unit, and is beneficial to realizing the constant-temperature and constant-humidity control of the air conditioner.
In some embodiments, the step 120 of determining a target speed gear of a centrifugal fan of the air conditioner based on the first temperature value and the target temperature value may include:
determining a first temperature inaccuracy value based on the first temperature value and the target temperature value;
and determining a target rotating speed gear based on the first temperature deviation value.
Wherein the first temperature deviation value reflects a difference between the first temperature value and the target temperature value.
According to the first temperature deviation value, the degree of adjustment of the air quantity of the evaporation side of the air conditioner can be judged, and then the target rotating speed gear of the centrifugal fan is determined.
In this embodiment, determining the target speed gear based on the first temperature deviation value may include:
determining a first temperature deviation difference value at the current moment based on the first temperature deviation value at the current moment and the first temperature deviation value at the previous moment;
and determining a target gear difference value of the rotating speed gear of the centrifugal fan and the target rotating speed gear at the current moment based on the first temperature deviation value and the first temperature deviation difference value at the current moment.
It can be understood that, in actual implementation, the target rotation speed gear of the centrifugal fan at the current moment is obtained by adjusting based on the target rotation speed gear at the previous moment, that is, the difference value between the rotation speed gear of the centrifugal fan at the current moment and the target gear of the target rotation speed gear is determined, and then the target rotation speed gear can be obtained.
For example, if the target rotational speed gear of the centrifugal fan at the previous moment is 3 gears, and the target gear difference between the rotational speed gear of the centrifugal fan at the current moment and the target rotational speed gear is 2 gears, the target rotational speed gear of the centrifugal fan at the current moment is 5 gears.
For another example, the target rotational speed gear of the centrifugal fan at the previous moment is 5 gears, the target gear difference between the rotational speed gear of the centrifugal fan at the current moment and the target rotational speed gear is-1 gear, and the target rotational speed gear of the centrifugal fan at the current moment is 4 gears.
In this embodiment, the first temperature deviation difference at the current time may be calculated according to the first temperature deviation value at the current time and the first temperature deviation value at the previous time, and then the target gear difference at the current time is determined according to the first temperature deviation value at the current time and the first temperature deviation difference.
In actual implementation, formulas may be applied
ΔD 2 ＝S 2 +ΔS 1
Determining a target gear difference value;
wherein, Δ D 2 Is a target gear difference value of the rotating speed gear of the centrifugal fan and the target rotating speed gear at the current moment, S 2 Is the first temperature deviation value, delta S, of the current time 1 The first temperature deviation difference value at the current moment; delta S 1 ＝S 2 -S 1 ，S 2 Is a first temperature deviation value, S, at the present time 1 The first temperature deviation value at the previous moment; s. the 2 ＝T 2 -T 0 ，T 2 Is a first temperature value, T, at the present moment 0 Is the target temperature value.
In this embodiment, the calculated target gear difference value needs to be rounded, for example, Δ D is calculated 2 And =1.6, the target gear difference is 1 gear.
It should be noted that an adjustment threshold range of the target gear difference may be set, and when the calculated target gear difference at the current time exceeds the adjustment threshold range, the target rotational speed gear at the current time is adjusted and determined according to the target gear difference at the current time.
And when the calculated target gear difference value at the current moment is within the range of the adjusting threshold, the target rotating speed gear at the current moment is not adjusted, and the target rotating speed gear at the current moment is the same as the target rotating speed gear at the previous moment.
For example, the adjustment threshold range is (-1, + 2), when the calculated target gear difference value at the current moment is 1, the target rotational speed gear at the current moment is not adjusted, the target rotational speed gear at the current moment is the same as the target rotational speed gear at the previous moment, and the setting of the adjustment threshold range can avoid frequent change of the gear of the centrifugal fan, which is beneficial to prolonging the service life of the centrifugal fan.
In some embodiments, the step 110 of obtaining a first temperature value between an electric heater and an evaporator of an air conditioner may include:
and acquiring a first temperature value of the air conditioner according to the target time interval.
In this embodiment, acquire the first temperature value of air conditioner according to the target time interval, also adjust centrifugal fan's rotational speed gear according to the target time interval, centrifugal fan's rotation adjusts the temperature between evaporimeter and the electric heater in the target time interval for the temperature value is stable, helps promoting the degree of accuracy that centrifugal fan gear adjusted, can also avoid the frequent change of centrifugal fan gear, helps prolonging centrifugal fan's life.
