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 silencer, an air conditioner and a control method of the air conditioner. The silencer comprises a silencer casing; the silencer casing is made of a piezoelectric material andcan be energized through a wire; and the silencer casing is mechanically deformed when being energized, the size of the silencer casing changes correspondingly with changes of the magnitude of current, so that the sound absorption peak frequency of the silencer changes accordingly. Through the silencer provided by the invention, the size of the silencer casing changes according to the inverse piezoelectric effect of the piezoelectric material by changing the magnitude of the current of the silencer at different operating frequencies of a compressor, thus, a sound absorption performance curveof the silencer is changed, and the sound absorption peak frequency is changed to the operating frequency, so that the noise reduction requirements at all compressor operating frequencies are met, andthe silencer has the good 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 ...
