Problems solved by technology
[0002] At present, conventional inverter air conditioners operate at the same ultra-breeze speed SUPSLOWFAN in silent mode. Under high heat conditions (indoor 27 / -, outdoor 24 / 18), the evaporator temperature T2 of the air conditioner can easily reach the set evaporator high temperature The protection temperature is TE7 / TE8, so that the air conditioner enters the protection program and turns off the fan or compressor, which seriously affects the comfort of the air conditioner users
[0003] Taking the 35 air conditioner as an example, when the SUPSLOWFAN is set to 300-400RPM, the quiet effect is good in the cooling operation mode of the air conditioner, but the evaporator temperature T2 tends to be greater than TE8=B°C in the heating operation mode under high heat conditions, so Entering the compressor shutdown protection program, the air conditioner starts and stops frequently, which seriously affects the user's comfort; when the SUPSLOWFAN is set to 450-550RPM, the mute effect of the air conditioner is better in the cooling mode, but in the high heat condition of the heating mode The temperature T2 of the lower evaporator is likely to be greater than TE7=A℃, thus entering the fan shutdown protection program. The fan starts and stops frequently, and the room temperature fluctuates greatly, which affects comfort; There will be no high temperature protection of the evaporator under high heat conditions, but in the cooling operation mode, the mute effect is poor, and the mute effect cannot be achieved

The invention provides a control method for an air conditioner. The control method comprises the steps of when the air conditioner is detected to enter a silent mode, judging a current running mode of the air conditioner; when the current running mode of the air conditioner is a refrigeration running mode, controlling an indoor fan of the air conditioner to run at a first rotating speed, and when the current running mode of the air conditioner is a heating running mode, controlling the indoor fan of the air conditioner to run at a second rotating speed, wherein the first rotating speed is smaller than the second rotating speed. Correspondingly, the invention also provides a control device for the air conditioner. According to the technical scheme, the ultra-silent function of the air conditioner under the refrigeration running mode can be guaranteed, and unnecessary protection on a compressor and a motor under some environmental working conditions of the heating running mode of the air conditioner can be avoided; therefore, the use comfortableness of the air conditioner is greatly improved.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method and an air conditioner control device.
