Another embodiment of the present application provides an air conditioner operation control method, as shown in a flowchart of fig. 2, the air conditioner operation control method including:
s21: judging whether the air conditioner meets cold air prevention control conditions, wherein the cold air prevention control conditions comprise starting in a heating mode and/or after defrosting is finished;
s22: if so, controlling the air conditioner to enter a cold air prevention control mode;

and/or the presence of a gas in the gas,
and the running time of the indoor fan at the first rotating speed is greater than or equal to the rotating speed of the indoor fan and is increased by a second time threshold.
After the indoor fan is started, the surface temperature T of the indoor heat exchanger is continuously detectedInner pipeIndoor fan running time tInner fanWhen the surface temperature T of the indoor heat exchangerInner pipeTemperature threshold T for increasing rotating speed of indoor fan2And the indoor fan operation time tInner fanNot less than first time threshold t for increasing indoor fan rotating speed2(ii) a Or the indoor fan rotates at the rotating speed S1Running time tInner fan S1The rotating speed of the indoor fan is increased by a second time threshold t3And when the air conditioner works, the indoor fan operates in a set windshield mode.
Namely:
after the indoor fan is started, when any one of the following conditions is met, the indoor fan rotates at the speed S1Lifting to set windshield operation:
condition A, TInner pipe≥T2And is andt inner fan≥t2
Condition B, tInner fan S1≥t3
In condition A, T2The preferable value range is 0-100 ℃, and under the general condition, T is2＞T1At the moment, the heat exchanger of the indoor unit reaches a higher temperature, large air volume can be adopted for exchanging heat with the heat exchanger, and the air flow passing through the heat exchanger of the indoor unit can be ensured to have a better heat exchange effect with indoor air. T is2The recommended value is 40 ℃.
t2The range of the retrievable value is 0-60 s, and the characteristic is that the shortest time of the change of the rotating speed of the fan under the condition is adopted to avoid TInner pipeThe indoor fan which ascends too fast does not stably run to the rotating speed S1Then, the system starts to run at an increased speed to a set windshield, resulting in abnormal noiseSound, therefore, to ensure stable operation of the fan, t2The recommended value is 30 s.
In condition B, t3The preferable range is 0-10 min. When the indoor fan has continuously operated t3When the time is long but the condition A is not met, the indoor fan rotating speed S still needs to be adjusted1The maximum time for lifting to the set windshield operation (namely the maximum time in the process of 'controlling the change of the rotating speed of the internal fan' is t)3). When T isInner pipe≥T2Under the condition of not being satisfied all the time, the rotating speed of the indoor fan is always lower by S1The operation is not capable of increasing the rotating speed to the user set windshield for a long time, which is easy to cause after-sale complaints, so t3And 5min is recommended as the value, and the wind speed control and the user experience requirements are considered.
S33: controlling the indoor fan to operate at a second rotating speed;
s34: and when the running time of the air conditioner at the second rotating speed exceeds a preset threshold value, controlling the lower air door to be opened.

When the rotating speed of the fan is changed, the lower air door is opened, abnormal noise such as surging and the like can be generated, so that after the anti-cold air control is quitted for 10s, the lower air door is opened again under the stable rotating speed of the fan, and the normal work of the system is ensured.
In the embodiment, when the second control parameter meets the cold air preventing exit condition, the air conditioner is controlled to exit the cold air preventing control mode, the cold air preventing control mode can be exited in time, normal operation of the air conditioner is realized, and when the running time of the air conditioner at the second rotating speed exceeds the preset threshold value, the lower air door is controlled to be opened, so that abnormal noises such as surge and the like are avoided, and the stability of the system is improved.
