Abstract

The utility model discloses a noise abatement apparatus for refrigeration systems, comprising a compressor, an air suction pipe, an air exhaust pipe and a sealed outer shell. The sealed outer shell covers the exteriors of the compressor, the air suction pipe, and the air exhaust pipe. One end of the air suction pipe and the air exhaust pipe is communicated with the compressor. The other end is threaded out of the sealed outer shell. The cavities of the compressor, the air suction pipe, the air exhaust pipe and the sealed outer shell are provided with foam by the together foaming of every component. The foam and every component are connected seamlessly. The compressor and pipelines are wrapped by the foam. The sealed outer shell covers the exteriors of the compressor and the pipelines wrapped by the foam. Therefore, the compressor, the air suction pipe and the air exhaust pipe just like suspended in the foam. Thus, vibration proof and sound proof actions are obtained. The noise abatement apparatus is particularly suitable for refrigerating appliances which require strict noise abatement such as an indoor air conditioner, a refrigerator, a fridge, etc.

Description

A kind of denoising device

Technical field

The utility model relates to a kind of device that reduces the refrigeration system noise.

Background technique

Compressor and suction, the noise that outlet pipe produced are the main sources of air conditioner running noises.Analyzing the reason of its generation, mainly is that the noise of compressor operating generation, noise, compressor and the pipeline vibration that pipeline vibration produces cause other component resonance and the noise of generation.These vibrations and noise have caused the severe noise pollution to Environmental Conditions, and simultaneously because the existence of vibrating, the pipeline life-span is affected, and occur the pipeline fatigue disconnected situation of shaking easily, influence unit working life.

At present in the air conditioner denoising device, about the device of compressor and suction, outlet pipe part noise reduction adopts following several mostly:

1, the noise that soundproof materials such as wool felt reduce compressor is set outside compressor.But owing to can't wrap up fully tightly, soundproof effect is limited.

2, on the compressor bottom, Rubber shock-absorbing pad is set, weakens the vibration transfer of compressor.But the vibration of just transmitting to the bottom that weakens, the vibration of compressor top is still very big, still can be delivered to other parts of unit by the suction tracheae.

3, reduce the noise of compressor at compressor outer installment sealing shell.Hermetic compressor can effectively reduce the noise of compressor itself, but can't reduce the vibration and the transfer of vibration of compressor.

4, will inhale, outlet pipe uses flexible pipe instead and reduces the transmission of suction and discharge pipeline to vibration of compressor.This method can reduce transfer of vibration, but can't effectively reduce the noise of compressor.

More than several modes often use together, and effect is still not ideal enough.

The model utility content

The purpose of this utility model is to provide a kind of denoising device, uses this device can effectively reduce compressor and suction, noise that outlet pipe produced.

For solving the problems of the technologies described above, the denoising device that the utility model provides comprises compressor, sucking pipe, outlet pipe, can, can covers on outside compressor and sucking pipe, the outlet pipe, sucking pipe, outlet pipe one end communicate with compressor, one end passes can, be provided with the foam that foams and form with each assembly in the cavity between compressor, sucking pipe, outlet pipe, can, this foam and each assembly seamless link.

As further preferred version of the present utility model, the structure of can for splitting.

As the further improvement of above-mentioned preferred version, can is that two semicircle door type structures to form form.

The foaming technique that uses in the air conditioner refrigerating industry is to be used to be incubated purpose basically at home.In fact, stabilizer also has the function of sound-absorbing and vibration damping.These characteristics based on stabilizer, compressor and suction tracheae can be placed a special use placement the container of stabilizer (for example polyurethane), foam together, after the foaming, each assembly of equipment and foam are combined closely, and seamless link not only can effectively absorb the noise of compressor, can also reduce the vibration of compressor and pipeline, reach the purpose that reduces the compressor assembly noise.

Adopt denoising device that compressor and pipe-line system foaming processing are had the following advantages:

1, reduces compressor noise greatly.Because the sound absorption of foam, the noise major part of compressor has been absorbed, so noise reduces greatly.

2, reduce the noise that pipeline resonance causes.Because pipeline is by relative fixed, and surrounded by foam all around, therefore can not produce resonance phenomenon, reduced the noise of whole unit.

3, reduce vibrations, prevent the pipeline fracture.Owing to the existence of pipeline vibrations, be easy to generate the phenomenon of pipeline fatigue fracture.After the pipeline vibrations reduced, the situation of pipeline fracture also can reduce in a large number.

Because the level of compressor reliability is higher, the possibility that compressor breaks down is smaller.Make provision against emergencies, the can of this structure can adopt two semicircle doors, and foam has the advantage of easy removal again, therefore, can not cause big influence for the maintenance of system.

Figure of description

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

Fig. 1 is the longitudinal section of denoising device.

Fig. 2 is the cross-sectional view of denoising device.

Embodiment

As shown in Figure 1 and Figure 2, denoising device comprises compressor 2, sucking pipe 4, outlet pipe 1 and the can 5 that is formed by two semicircle door type structures to form, can 5 covers on outside compressor 2 and sucking pipe 4, the outlet pipe 1, sucking pipe 4, outlet pipe 1 one ends communicate with compressor 2, one end passes can 5, be provided with the foam 3 that forms by the stabilizer foaming in the cavity that compressor 2, sucking pipe 4, outlet pipe 1, can are 5, foam 3 and each assembly seamless link.Therefore, compressor 2 assemblies such as grade are as a whole with 3 one-tenth of foams.Compressor 2 and sucking pipe 4, outlet pipe 1, power line 6 are wrapped in the foam 3, and can 5 covers on the compressor 2 that wrapped up by foam 3 and sucking pipe 4, outlet pipe 1, power line 6 outsides.So, compressor 2 and sucking pipe 4, outlet pipe 1 in foam 3, thereby have played the effect of shock-absorbing and sound insulation as " suspension ".Compressor 2 is connected with power supply by power line 6.During compressor 2 work and since with on every side foam 3 be to combine closely, seamless link, therefore, each assembly such as compressor 2 and sucking pipe 4, outlet pipe 1 is relative fixed all, greatly reduces the noise of compressor and the noise that pipeline resonance causes.

This denoising device is specially adapted to room air conditioner, refrigerator, refrigerator and other is in the electric refrigerator of noise requirements than strictness.
