Embodiment 1

[0038] like figure 1 As shown, an air-conditioning control method includes the following steps:

[0039] S1: In the cooling mode, obtain the indoor ambient temperature Ta and the set cooling temperature Ts in real time, and calculate the difference between the indoor ambient temperature Ta and the set cooling temperature Ts △T1, △T1=Ta-Ts;

[0040] S2: Judging whether △T1 satisfies △T1≤a°C: Yes, the compressor and fan of the outdoor unit of the air conditioner are turned off, and at the same time, the air conditioner enters the control mode of the indoor fan of the indoor unit, and the control mode of the indoor fan controls the internal fan The rotation speed is controlled; if not, the air conditioner operates normally in cooling mode.

[0041] Further, as figure 2 As shown, the indoor fan control mode of the air conditioner entering the indoor unit includes:

[0042] S2.1: Obtain the rotational speed Vr1 of the internal fan when the air conditioner enters the internal fa...

Abstract

The invention provides a control method and an air conditioner, and relates to the technical field of air conditioners. In a refrigerating mode, the indoor ambient temperature Ta and the set refrigerating temperature Ts are acquired in real time, the distance deltaT1 of the indoor ambient temperature Ta and the set refrigerating temperature Ts is calculated, and deltaT1=Ta-T2; whether deltaT1 meets the condition that deltaT1<=a DEG C is judged; if yes, a compressor and a fan of an air conditioner outdoor unit are shut down, meanwhile, the air conditioner enters an inner fan control mode of anindoor unit, and the inner fan control mode controls the rotating speed of an inner fan; and otherwise, the air conditioner normally operates in the refrigerating mode. The inner fan rotating speed iscontrolled after the refrigerating mode reaches the temperature for shutdown, the method of controlling the inner fan to be slowly shut down is adopted, the low temperature of the inner fan in the refrigerating mode is fully utilized, and the energy efficiency of the air conditioner is improved. The phenomenon that when the indoor ambient temperature reaches the set refrigerating temperature in the refrigerating mode, the inner fan continues to run to cause electric energy waste, or noise is too high due to emergency shutdown of the inner fan is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and an air conditioner. Background technique [0002] At present, with the development of intelligence, air conditioners have higher and higher requirements for energy saving and comfort. When the air conditioner is running in the cooling mode, after the set cooling temperature reaches the indoor ambient temperature (the cooling reaches the temperature and stops), the fan of the indoor unit still blows cold air to the room according to the set internal fan speed. If the speed of the internal fan is set to the strong gear before the temperature is reached and the machine stops, the indoor unit will always run at the strong gear after reaching the set temperature. At this time, the power consumption of the internal motor is high, and there is no cooling effect after running for a long time, resulting in power consumption. Contents of th...
