Embodiment 1

[0044] The number of distribution holes 35 of the muffler of the air conditioner of the present embodiment is 2, as Figure 8 As shown, the solid line is the frequency response graph of the air conditioner of this embodiment, and the dotted line is the frequency response graph of the air conditioner without a muffler. Through comparison, it can be seen that compared with the air conditioner without a muffler, the air conditioner of this embodiment can significantly filter and eliminate the noise of the four frequencies, can expand the frequency range of the noise reduction, and can further improve the overall frequency characteristics of the noise reduction. The air conditioner of the example has obvious noise reduction advantages.

Embodiment 2

[0046] The number of distribution holes 35 of the muffler of the air conditioner of the present embodiment is 6, as Figure 9 As shown, the solid line is the frequency response graph of the air conditioner of this embodiment, and the dotted line is the frequency response graph of the air conditioner without a muffler. Through comparison, it can be seen that compared with the air conditioner without a muffler, the air conditioner of this embodiment can significantly filter and eliminate the noise of the four frequencies, can expand the frequency range of the noise reduction, and can further improve the overall frequency characteristics of the noise reduction. The air conditioner of the example has obvious noise reduction advantages.

Abstract

The invention discloses a muffler and an air conditioner including the muffler. The muffler includes a distributor, a first cavity and a second cavity, and the first cavity includes a first cavity body, a first transition cavity and a first constriction cavity. The second cavity includes a connection port, a second transition cavity, a second cavity, a third transition cavity and a second constriction, and the distributor includes a third constriction, a fourth transition cavity and a third cavity. The muffler can make the flow path of the refrigerant expand and shrink multiple times, so that the passage frequencies of each section of the cavity are staggered from each other, and the sound of multiple wavelengths and frequencies can be eliminated, and the range of muffled frequencies can be expanded. The muffler can break up the bubbles in the refrigerant in the gas-liquid mixed state, making the flow of the refrigerant more uniform, and also improving the stress and vibration of the piping. The muffler can play a very good muffler effect on the compressor transmission sound, refrigerant flow sound and pipeline beating vibration sound in the air conditioning system, and can improve the total muffler volume.

Description

technical field [0001] The invention relates to the technical field of noise control, in particular to a muffler and an air conditioner including the muffler. Background technique [0002] The frequency conversion air conditioner is based on the ordinary air conditioner and selects the frequency conversion special compressor, adds the frequency conversion control system, can automatically provide the required energy according to the temperature of the room. That is, when the indoor temperature reaches the set value, the main unit of the air conditioner can maintain a constant speed at this temperature to achieve the highest temperature. The speed directly affects the efficiency of use. The frequency converter is a control system used to control and adjust the speed of the compressor, making it more prominent in terms of energy saving and comfort, but there are problems with noise during operation. The operating frequency of the inverter air conditioner increases during the ...
