Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example one
As shown in fig. 1, an air conditioner control method includes the following steps:
s1: under a refrigeration mode, acquiring indoor environment temperature Ta and set refrigeration temperature Ts in real time, and calculating the difference delta T1 between the indoor environment temperature Ta and the set refrigeration temperature Ts, wherein delta T1 is Ta-Ts;
s2: judging whether the delta T1 meets the condition that delta T1 is not more than a DEG C: closing a compressor and a fan of an outdoor unit of an air conditioner, and simultaneously, enabling the air conditioner to enter an inner fan control mode of an indoor unit, wherein the inner fan control mode controls the rotating speed of the inner fan; and if not, the air conditioner normally operates in a refrigeration mode.
Further, as shown in fig. 2, the entering of the air conditioner into the internal fan control mode of the indoor unit includes:
s2.1: acquiring the rotating speed Vr1 of the inner fan when the air conditioner enters an inner fan control mode of the indoor unit;
s2.2: judging whether Vr1 meets the condition that Vr1 is not more than b revolutions per minute: if yes, the inner fan stops operating after the rotating speed Vr1 is kept operating for a time delta t 1; and if not, the air conditioner enters an inner fan rotating speed control mode of the indoor unit, and the inner fan rotating speed control mode continues to control the rotating speed of the inner fan.
Further, as shown in fig. 3, the entering of the air conditioner into the internal fan rotation speed control mode of the indoor unit includes:
s2.2.1: the inner fan keeps the current constant rotating speed operation, when the temperature Te of the inner disc of the evaporator rises to the temperature T, the rotating speed of the inner fan correspondingly decreases by delta Vr (T)
S2.2.2: continuing to operate according to S2.2.1 until the rotating speed of the inner fan is reduced to b revolutions per minute when the temperature of the inner disc of the evaporator is increased to the indoor environment temperature Ta;
s2.2.3: and the inner fan stops running after keeping the rotating speed b/min running for delta t 1.
It should be noted that the S2.2.1 step may be performed multiple times. In the refrigeration mode, the temperature of the inner disc of the evaporator is not higher than the indoor environment temperature, when the temperature of the inner disc of the evaporator rises to be lower than the set transition temperature and can reach the indoor environment temperature, the rotating speed of the inner fan is reduced to b revolutions per minute when the temperature of the inner disc of the evaporator rises to the indoor environment temperature, and the inner fan stops running after the time of keeping the rotating speed of the inner fan to be b revolutions per minute running is delta t 1.
Further, the inner disk temperature Te of the evaporator is higher by the same or different temperature per liter, and the decrease amount of the rotation speed decrease is the same or different.
That is, when the evaporator inner disk temperature Te rises to the temperature T, the rotation speed of the inner fan is correspondingly decreased by Δ vr (T). In the step of repeating S2.2.1, the temperature amplitude of each rise of the temperature of the inner disk of the evaporator and the reduction amount of each reduction of the rotating speed of the inner fan can be the same or different.

However, Δ vr (T) may have no specific relationship with T, and may vary with different operating conditions and air conditioner models. For example, when the temperature of the inner disc of the evaporator rises by 2 ℃, the rotating speed of the inner fan is reduced by 300 revolutions per minute; when the temperature of the inner disc of the evaporator continues to rise by 2 ℃, the rotating speed of the inner fan is still reduced by 300 r/min.

For another example, when the temperature of the inner disc of the evaporator rises by 2 ℃, the rotating speed of the inner fan is reduced by 300 revolutions per minute; when the temperature of the inner disc of the evaporator continues to rise by 2 ℃, the rotating speed of the inner fan is reduced by 600 revolutions per minute. Further, the value range of a is as follows: 0.5. ltoreq. a.ltoreq.2, a preferably being 1; the value range of the amplitude delta T of each rise of the temperature Te of the inner disc of the evaporator is as follows: delta T is more than or equal to 2 ℃ and less than or equal to 4 ℃, and the delta T is preferably 2 ℃ or 3 ℃; the value range of delta t1 is as follows: 60 seconds < Deltat 1 < 150 seconds, Deltat 1 preferably 120 seconds. This is the preferred value in the solution of the present embodiment, which is the result of the trial and error verification performed by the inventor, in this case, the efficiency of the present control method can be maximized.

The electric energy waste caused by continuous operation of the inner fan or the excessive noise caused by sudden stop of the inner fan when the indoor environment temperature reaches the set refrigeration temperature in the refrigeration mode is avoided. The change of the temperature of the inner disc of the evaporator is adopted to control the rotating speed of the inner fan, so that the temperature of the inner disc of the evaporator is more fully utilized.

Further, as shown in fig. 4, the entering of the air conditioner into the internal fan rotation speed control mode of the indoor unit includes:

Preferably, however, the set transition time for operating the inner fan at a constant rotational speed is different, and the rotational speed of the inner fan is decreased by the same amount.

For another example, after the maintaining rotating speed Vr1 of the inner fan runs for 20 seconds, the rotating speed of the inner fan is reduced by 300 r/min to Vr 3; and when the maintaining rotating speed Vr3 of the inner fan runs for 30 seconds, the rotating speed of the inner fan is continuously reduced by 600 r/min.

The electric energy waste caused by continuous operation of the inner fan or the excessive noise caused by sudden stop of the inner fan when the indoor environment temperature reaches the set refrigeration temperature in the refrigeration mode is avoided. The time change is adopted to control the rotating speed of the inner fan, and the temperature of the inner disc of the evaporator is not required to be acquired every time.
