Method and device for reducing noise of air conditioner and air conditioner

Abstract

The invention discloses a method and device for reducing noise of an air conditioner and the air conditioner. An air conditioner super-strong gear compressor stably enters logical judgment, a first preset temperature value a is set, and a preset rotating speed value is set; a first temperature value t1 in the middle of an evaporator is obtained every time t, and a second temperature value t2 of a gas collecting pipe at an outlet of the evaporator is obtained every time t; N temperature difference values delta t of the evaporator every time t are recorded; N variance values S of the temperature difference values delta t of the N evaporators are obtained; whether the air conditioner generates noise or not is judged according to the variance values S and the first preset temperature value a; a target operation parameter value of the air conditioner is determined according to a judgment result; and the air conditioner is controlled to operate at a target operation parameter operation value. The method of the invention has the advantages that the rotating speed of an inner fan is adjusted by judging a temperature difference value between an evaporator middle temperature sensing bulb and an evaporator outlet temperature sensing bulb, so that the rotating speed of the inner fan is stable, the noise of the air conditioner is reduced, the use comfort of a user is improved, and fault codes are displayed by recording the number of times of triggering the logic.

Description

Technical field [0001] The present invention relates to the technical field of air conditioning equipment, in particular a method, apparatus, and air conditioner that reduces air conditioning noise. Background technique [0002] At present, the main noise source of household air conditioning indoor machines is the wind sound of the air and the motor, and the inner air conditioner can not be used due to life problems after long-term use. The mode is running, and the user will set a super-power, the motor is not allowed to reach the maximum speed of the speed, but the speed of the motor will suddenly beat the small, and the wind that runs the winding leaf will also Suddenly, the small, affecting the user experience. [0003] A air conditioner indoor air conditioner method, a control system, and an air conditioner thereof are disclosed in the prior art. The solution, but this solution requires AI modules and processing modules, while the motor speed is constantly changing, the cost ...

AI Technical Summary

Problems solved by technology

[0002] At present, the main noise source of the indoor unit of the household air conditioner is the wind noise of the cross-flow fan blades and the electromagnetic sound of the motor. However, after a long period of use of the current household air conditioner, the motor of the internal unit may not be able to operate at a high speed for a long time due to life issues. Mode operation, and at this time the user sets the super gear, the motor receives the command of the maximum speed, but cannot reach the maximum speed, the speed of the motor will fluctuate, and the wind noise generated by the cross-flow fan blades will also Big and small, affecting user experience

[0003] In the prior art, an air supply control method and control system of an air conditioner indoor unit and its air conditioner are disclosed. The patent number is CN112797483A. solution, but this solution requires an AI module and a processing module, and at the same time needs to constantly change the motor speed, the cost is high and the service life of the internal motor will be reduced
