Alternatively, in one embodiment, the first buffer layer 41 and the second buffer layer 42 are made of elastic materials, respectively. Thus, in addition to the elasticity of the first buffer layer 41 itself being able to absorb the shock of the exhaust pipe 21, the first buffer layer 41 is able to generate a damping effect on the exhaust pipe 21 to alleviate the shock and reduce the stress of the exhaust pipe 21; similarly, in addition to the elasticity of the second buffer layer 42 itself being able to absorb the shock of the return air pipeline 22, the second buffer layer 42 is able to generate a damping effect on the return air pipeline 22 to alleviate the shock and reduce the stress of the return air pipeline 22.

Optionally, referring to fig. 4, in an embodiment, the exhaust pipeline 21 has a first straight pipe portion, and the first buffer layer 41 is wrapped on the first straight pipe portion; therefore, the first buffer layer 41 is contacted with the first straight pipe part more tightly, and the damping effect of the first buffer layer 41 is improved. Specifically, the quantity of first straight tube portion is a plurality of, and a plurality of first straight tube portion are parallel to each other, and a plurality of first straight tube portions are tied up to first buffer layer 41, so, a plurality of first straight tube portions can promote the shock attenuation effect through the whole linkage that carries out of first buffer layer 41.

Optionally, the second buffer layer 42 sequentially passes through the gap between two adjacent air return pipes 22, so that a closer contact between the second buffer layer 42 and the air return pipes 22 can be maintained to reduce vibration.

Optionally, in one embodiment, vibration and stress optimization are performed on a pipeline system formed by the exhaust pipeline 21, the air return pipeline 22 and the compressor 1 according to the following method, wherein the method comprises the following steps of 1, driving the compressor 1 to operate, testing vibration and stress levels, adjusting the shape, length and space trend of the exhaust pipeline 21/the air return pipeline 22, and determining an optimized pipeline through experiments to enable the vibration and stress of the exhaust pipeline 21/the air return pipeline 22 to reach an optimal state; step 2, using a damping mechanism (a damping mechanism: a first damping mechanism 31 and/or a second damping mechanism 32) on the exhaust pipeline 21/the air return pipeline 22, determining the optimal damping mechanism configuration and the optimal damping mechanism placing position through tests, and further optimizing the vibration and stress levels of the exhaust pipeline 21 and the air return pipeline 22; and 3, wrapping and supporting the exhaust pipeline 21 and the air return pipeline 22 by using the first buffer layer 41 and the second buffer layer 42, and further reducing the vibration and stress levels of the exhaust pipeline 21 and the air return pipeline 22.

Further, referring to fig. 1 and 2, as an embodiment of the air conditioner provided by the present invention, the first damping mechanism 31 is a first extension pipe that extends the length of the exhaust pipe 21, and/or the second damping mechanism 32 is a second extension pipe that extends the length of the return pipe 22. Thus, the first extension pipe increases the weight of the exhaust pipeline 21, reduces the resonance frequency of the exhaust pipeline 21, and reduces the vibration intensity of the exhaust pipeline 21; the second extension tube increases the weight of the return air line 22, reduces the resonance frequency of the return air line 22, and reduces the vibration intensity of the return air line 22.

Therefore, the first damping block increases the weight of the exhaust pipeline 21, reduces the resonance frequency of the exhaust pipeline 21 and reduces the vibration intensity of the exhaust pipeline 21; the second damping mass increases the weight of the return air line 22, reduces the resonance frequency of the return air line 22, and reduces the vibration intensity of the return air line 22. Specifically, in one embodiment, the first damping mass and the second damping mass are each a counterweight.

In this manner, the shock of the first damping block can be absorbed by the first buffer layer 41, and the shock of the second damping block can be absorbed by the second buffer layer 42.

Further, referring to fig. 1 and 2, as an embodiment of the air conditioner provided by the present invention, the exhaust duct 21 is supported on the first buffer layer 41, and/or the return duct 22 is supported on the second buffer layer 42. Thus, the exhaust pipe 21 can improve the contact tightness between the exhaust pipe 21 and the first buffer layer 41 under the support of the first buffer layer 41, and the first buffer layer 41 can further reduce the vibration of the exhaust pipe 21 and reduce the stress of the exhaust pipe 21; the contact tightness between the return air pipe 22 and the second buffer layer 42 can be improved by the return air pipe 22 supported by the second buffer layer 42, and the second buffer layer 42 can further reduce the vibration of the return air pipe 22 and the stress of the return air pipe 22.

Further, referring to fig. 3, as an embodiment of the air conditioner provided by the present invention, the number of the first buffer layers 41 is at least two, and the exhaust duct 21 is sandwiched between at least two first buffer layers 41. Thus, when the exhaust pipe 21 is sandwiched by at least two layers of the first buffer layers 41, the exhaust pipe 21 can be in close contact with the contacting first buffer layers 41 and reduce the vibration of the exhaust pipe 21.

Optionally, in an embodiment, at least two first buffer layers 41 are disposed parallel to each other.

Further, referring to fig. 5, as a specific embodiment of the air conditioner provided by the present invention, at least two first buffer layers 41 are disposed to cross each other. In this way, the first buffer layers 41 arranged in a crossing manner can be interlocked with each other to reduce respective vibrations.

Optionally, in one embodiment, at least two first buffer layers 41 are twisted into a curved shape to absorb shock.

Further, referring to fig. 1 and fig. 2, as an embodiment of the air conditioner provided by the present invention, the number of the second buffer layers 42 is at least two, and the air return pipeline 22 is clamped between at least two second buffer layers 42. In this way, when at least two second buffer layers 42 sandwich the return air pipe 22, the return air pipe 22 can be in close contact with the contacting second buffer layers 42 and reduce the vibration of the return air pipe 22.

Optionally, in one embodiment, at least two second buffer layers 42 are disposed parallel to each other.

Further, referring to fig. 1 and 2, as an embodiment of the air conditioner provided by the present invention, at least two second buffer layers 42 are disposed to cross each other. In this way, the second buffer layers 42 arranged in a crossing manner can be interlocked with each other to reduce respective vibrations.

optionally, in one embodiment, at least two second buffer layers 42 are twisted to absorb shock.

Further, referring to fig. 3, as an embodiment of the air conditioner provided by the present invention, the first buffer layer 41/the second buffer layer 42 is sandwiched between the exhaust duct 21 and the return duct 22. In this way, the exhaust duct 21 and the return duct 22 share the first/second buffer layers 41/42, which can save materials, and when the vibration on the exhaust duct 21 and the vibration on the return duct 22 are reduced by the first/second buffer layers 41/42, respectively, the vibration frequencies on the exhaust duct 21 and the return duct 22 can be mutually offset when they are not synchronous.

Alternatively, only the first buffer layer 41 or the second buffer layer 42 is clamped between the exhaust pipeline 21 and the return pipeline 22; first buffer layer 41 and second buffer layer 42 may be stacked together and sandwiched between exhaust duct 21 and return duct 22.

Further, referring to fig. 1 and fig. 2, as an embodiment of the air conditioner provided by the present invention, a first elastic layer wrapped on the exhaust duct 21 is sandwiched between the exhaust duct 21 and the first buffer layer 41; and/or a second elastic layer wrapped on the air return pipeline 22 is clamped between the air return pipeline 22 and the second buffer layer 42. Therefore, the friction coefficient and the contact elasticity with the first elastic layer (such as a soundproof cotton material) are increased by adding a layer of wrapping elastic material outside the exhaust pipeline 21, so that the absorption effect of vibration and stress of the exhaust pipeline 21 is improved; similarly, the absorption effect of vibration and stress of the air return pipeline 22 is improved by adding a layer of wrapping elastic material outside the air return pipeline 22 to increase the friction coefficient and contact elasticity with the second elastic layer (such as soundproof cotton material).

Specifically, in one embodiment, the first elastic layer is PE insulation cotton/high density sponge; the second elastic layer is PE heat-insulating cotton/high-density sponge.

Further, referring to fig. 1 and 2, as an embodiment of the air conditioner provided by the present invention, the first buffer layer 41 and/or the second buffer layer 42 are/is soundproof cotton. Thus, the soundproof cotton has low cost.

Specifically, in one embodiment, the material of the soundproof cotton may be any one of thorium wool material, epoxy felt material and common felt material.

Optionally, in an embodiment, the air conditioner is an electrolytic capacitor-free variable frequency air conditioner, since the electric controller removes a high-voltage electrolytic capacitor for storing energy, and the electric power output by the variable frequency controller to the compressor 1 changes with the periodic sinusoidal pulsation of the ac mains, vibration and stress of the exhaust pipe 21 and the return pipe 22 are further increased, and by using the first damping mechanism 31, the second damping mechanism 32, the first buffer layer 41, and the second buffer layer 42 in the present technical solution, the vibration and stress level can be significantly reduced. Specifically, in one embodiment, 1, under the condition without soundproof cotton, the compressor 1 is driven by using a conventional variable-frequency electric control drive with electrolysis, and the pipelines are tested and optimized, so that the vibration and stress of the exhaust pipeline 21 and the return air pipeline 22 reach the optimal state. 2. The vibration and stress levels of the exhaust pipeline 21 and the return pipeline 22 are further reduced by matching the damping blocks. 3. The exhaust pipeline 21 and the return air pipeline 22 are wrapped and supported by using a soundproof cotton mode, and the best wrapping scheme is selected as the final product embodiment by trying the plurality of wrapping schemes by using electrolytic-free variable frequency electric control.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
