A compressor assembly according to an embodiment of the present invention is described below with reference to the accompanying drawings.

Referring to fig. 1-4, a compressor assembly according to an embodiment of the present invention includes a compressor 1, a liquid reservoir 2 and a wavelength tube silencer 3. The compressor 1 can compress a refrigerant. The accumulator 2 is connected to the suction side of the compressor 1, and the refrigerant can flow from the accumulator 2 into the compressor 1.

The wave tube silencer 3 defines a sound-deadening chamber 32 with only one flow opening 321 therein, the wave tube silencer 3 is provided on at least one of the compressor 1 and the reservoir 2, the sound-deadening chamber 32 communicates with the inner chamber 12 of the compressor 1 through the flow opening 321, and/or the sound-deadening chamber 32 communicates with the inner chamber of the reservoir 2 through the flow opening 321, the sound-deadening chamber 32 having a sound-deadening function. For example, the compressor 1 is provided with the wave tube silencer 3, and the sound-deadening chamber 32 communicates with the inner chamber 12 of the compressor 1 through the flow port 321. Alternatively, the liquid reservoir 2 is provided with the wavelength tube silencer 3, and the silencing chamber 32 is communicated with the inner cavity of the liquid reservoir 2 through the flow port 321. Alternatively, the compressor 1 and the reservoir 2 are both provided with the wavelength tube muffler 3, the muffling chamber 32 of the wavelength tube muffler 3 provided in the compressor 1 communicates with the inner chamber 12 of the compressor 1 through the flow port 321, and the muffling chamber 32 of the wavelength tube muffler 3 provided in the reservoir 2 communicates with the inner chamber of the reservoir 2 through the flow port 321.

The wavelength tube silencer 3 in the present application has a silencing and noise reducing effect. When the incident sound wave enters the sound-deadening chamber 32 through the flow port 321, the incident sound wave is reflected in the sound-deadening chamber 32, and a reflected sound wave can be generated, and the incident sound wave and the reflected sound wave have a phase difference. The incident sound wave and the reflected sound wave having a phase difference may interfere with each other, so that the incident sound wave and the reflected sound wave cancel each other, thereby allowing the muffling chamber 32 to muffle noise.

When the compressor assembly works, the refrigerant flows into the compressor 1 from the liquid storage device 2, and the compressor 1 compresses the refrigerant to a high-pressure state and generates large air sound waves. Part of noise sound waves can enter the silencing chamber 32 from the circulation port 321, the refrigerant hardly enters the silencing chamber 33, the part of air sound waves interfere in the silencing chamber 32, the sound wave energy is consumed, and therefore the silencing chamber 32 can conduct silencing treatment on the part of air sound waves, the whole noise of the compressor assembly is reduced, and the noise transmitted to the outside from the compressor assembly is reduced.

Since the images of the incident sound wave and the reflected sound wave are both sine functions, the above definition of the length of the wavelength tube 31 can make the incident sound wave and the reflected sound wave have a phase difference of approximately 180 ° at the flow port 321, so that the effect of mutual interference between the incident sound wave and the reflected sound wave is better, and the wavelength tube silencer 3 has better silencing and noise reduction effects. The air sound wave generated in the compressor 1 enters the sound-deadening chamber 32 from the circulation port 321, the air sound wave is reflected in the sound-deadening chamber 32 to form a reflected air sound wave, and then the air sound wave interferes with the reflected air sound wave at the circulation port 321 to reduce the sound wave energy, thereby reducing the noise of the compressor component.
