Problems solved by technology

Since the operating frequency of the compressor of the inverter air conditioner changes, in the noise reduction design, only the frequency value with the loudest noise can be selected for control, resulting in that the noise control of the compressor at other operating frequencies cannot be optimal.

Abstract

The invention provides a muffler, an air conditioner, and a control method for the air conditioner, wherein the muffler includes: a muffler shell made of piezoelectric material, the muffler shell can receive current through wires, and when the muffler shell is connected to the current Mechanical deformation occurs, and the size of the muffler shell changes accordingly with the change of the access current, so that the sound absorption peak frequency of the muffler changes accordingly. The muffler provided by the present invention changes the size of the muffler casing according to the inverse piezoelectric effect of the piezoelectric material by changing the magnitude of the current connected to the muffler at different operating frequencies of the compressor, thereby changing the sound absorption performance curve of the muffler, and changing the sound absorption peak frequency Move to this operating frequency, so as to meet the noise reduction requirements of each compressor operating frequency, so that the muffler has better vibration and noise reduction performance.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a muffler, an air conditioner, and a control method for the air conditioner. Background technique [0002] The noise of an air conditioner is an important assessment standard for evaluating performance, and the vibration of the compressor and its piping is the main reason for the vibration and noise of the outdoor unit. Since the operating frequency of the compressor of the inverter air conditioner changes, in the design of noise reduction, only the frequency value with the loudest noise can be selected for control, resulting in that the noise control of the compressor at other operating frequencies cannot be optimal. Contents of the invention [0003] The present invention aims to solve at least one of the above technical problems. [0004] Therefore, the object of the first aspect of the present invention is to provide a muffler. [0005] The object of the ...
