Outdoor air conditioner soundproof baffle
Outdoor air conditioner soundproof baffle, we recuperate, if there is a little bit of noise will make people hard to bear, so the soundproof design is a very need to pay attention to a point, soundproof effect is good, not only will be able to have a good night's sleep. The following share outdoor air conditioning unit soundproof baffle.
Outdoor air conditioner soundproof baffle 1
Air conditioner soundproofing is generally used in the soundproofing method of soundproof barrier wall and soundproof room, for different factors using different soundproofing methods.
What soundproofing materials are used for soundproofing of air conditioning units?
A sound wall
1, air conditioning unit sound barrier equipment is relatively simple, first of all, we need to know the location of the air conditioning unit, the height of the size of the noise source, the noise source, is isolated from the direction of the source of noise, the location.
2, the design of air conditioning unit sound barrier screen installation location, spacing, column installation method, air conditioning unit installation methods are generally:
(1) column extension playing in the daughter wall fixed
(2) flange to do the embedded parts fixed
(3) horse riding Zhuang type fixed
(4) 7-zigzag fixed
(5) Fixed base welding
3, air conditioning unit sound barrier is usually installed on the wall, ground, roof
(1) wall installation of air conditioning unit sound barrier can be designed and installed according to the site conditions
(2) the ground is a common one, regardless of the considerations
(3) roof is a common one, the installation of roof waterproofing layer design should be considered. (4) The roof is a common one, the installation should consider the design of the waterproof layer of the roof, and the installation of the air conditioning unit sound barrier should take advantage of the favorable conditions to do part of the diagonal.
4, installed air conditioning unit sound barrier (especially the roof) wind resistance, to avoid future corrosion of the columns or noise screen body to affect the number of years of use, after the installation of the installation in a timely manner to do a good job in the installation of the bump in a timely manner. After installation, we should check the looseness of the bolts regularly.
5, air-conditioning unit sound barrier installation for high-altitude work, so the installation process of construction workers should pay attention to personal safety, in the screen equipment to avoid the installation process, workers bump constitute years of personal injury.
Second, the sound insulation room
Air conditioning sound insulation noise reduction soundproof room, we use the sound insulation cotton, perforated sound-absorbing panels, sound boards, sound felt and other acoustic materials made.

air conditioner sound insulation board installed and removed there is a disturbing noise
Look at the 76 4th floor residents home to see, right below the window, is the four air conditioners, the distance between the two is only about twenty meters.
From a distance, it seems that the air-conditioning unit was wrapped tightly, and closer to find that the sound insulation board of the upper machine has been removed, replaced by a layer of the sunshade is not acoustic, and the lower layer of the sound insulation board has been partially removed, with the machine running, even during the day can be clearly heard in the residents' home roar, and the sound of this sound in the dead of night is even more pronounced.
Mr. Zang, the head of the building team, said: "It was still running at two o'clock last night. It's very noisy, and we can hear it here in one room and two rooms, including three rooms. Do not disturb the normal life of our residents, we also have high school students here, there are people commuting to work, you go on like this then not."
Residents reflected, these from the next door to the central air-conditioning outboard noise has been the second time to disturb the people, the original, as early as the year before, these air-conditioning outboard installation because of the noise, caused the residents to complain. Residents and stores in several discussions and communication after the decision to install soundproof panels, after the impact is indeed much smaller, the two sides also peace and quiet. But did not expect, last summer, the store and remove the original installation of part of the sound insulation board, which makes the noise again comeback.
Building team leader Mr. Zang said: "soundproof board all get well, the sound is really no, to last summer, they removed the soundproof board, above all lifted off, the sound came out."
As for the reason for the demolition, the store to the residents to give the explanation is that these soundproof panels wrapped around the air conditioning unit, and the hot air blowing out of the unit hit the soundproof panels, the formation of the return wind, resulting in the summer machine in the high temperature for a long time can not dissipate the heat, resulting in damage.
The building team leader Mr. Zang said: "They said our air conditioning is broken, call people to repair once on more than 10,000 yuan, we have invoices here, I said your air conditioning is broken, we residents are not any problem, because it is you who disturbed the people."
Regrettably, although the store in the process of removing the soundproof board, has been and residents to maintain communication, but also timely to the residents announced a revised program, but the final improvement of the results did not make the residents satisfied.
Shanghai Zheng Pu medical beauty clinic responsible person said: "After doing so, they found that not as imagined so satisfied, and then in the year before the 26th, 27th, our street urban management teacher to mention this problem, when the New Year, I can not find people to repair. I want to find this project around to do it quickly, but because it may not have been to the 15th, 16th, a lot of places have not resumed work, do this a little difficult."
At present, the city management department has intervened in this matter, and is actively promoting the store to carry out timely rectification.
Yangjing Street Comprehensive Administrative Law Enforcement Team deputy director Li Ge said: "Tell him a you carry out the corresponding rectification, make it shutters up, the sound goes down, in addition to the addition of a sound wall here, but also to minimize the impact of residential buildings. Although not over the standard (60 decibels), but the noise is still there, we will urge the store to come up with a rectification program, they will also be the recent rectification program to us, to minimize the noise, like now this hole open outside, all to be rectified."
Outdoor air conditioning host soundproof baffle 3A, what is soundproof cotton
Soundproof cotton in the construction of the building decoration project with more polyester fiber material is mainly filled in the gap in the keel, is generally the choice of 5cm soundproof cotton, soundproof cotton uniformly adhered to the keel partitions so that you can play the role of soundproof cotton.
Daily life is more common in the home decoration sound insulation is rubber sound insulation cotton, composite rubber sound insulation cotton this is can be paved in the indoor walls, or KTV, audio-visual room, etc., can play a certain sound insulation and sound absorption effect.
Second, what is the sound insulation board
The sound insulation board is actually a composite panel that can be soundproof, most of which are made of fiberboard, plastic panels, density boards and so on composite, there is also a kind of damping soundproofing board. Composite sound insulation board this board sound insulation effect depends mainly on the quality of composite panels, the higher the density of the board sound insulation effect is better, and this board is generally used in the scene will be wider than the sound insulation cotton range, such as clubs, meeting rooms, KTV, movie theaters, etc., most of which are used to play the effect of sound insulation board sound insulation.
Third, the sound insulation cotton and sound insulation board which is good What is the difference
1, the noise reduction principle is different
sound insulation cotton absorbed noise sound waves through the countless holes in the material and friction within the material consume each other to reduce the noise; while the sound insulation board is through the reduction of noise, the sound waves penetration, has the effect of noise, the sound of the noise, the sound of the sound of the sound of the noise. penetration of sound waves, with quite a certain degree of . Vibration damping effect.
Acoustic panels are a high-density soundproofing material, the use of acoustic panels can effectively prevent a portion of the noise radiated outward propagation, and its most important feature is that the amount of sound insulation can be up to 30 decibels.
2, installation and use of different environments
The installation and use of acoustic cotton and acoustic panels are different environments, acoustic cotton is more used in the automotive process, while the acoustic panels in the decoration and automotive technology have been involved, so in the choice of the noise reduction material, but also according to the different circumstances and requirements, choose the appropriate sound insulation and sound absorption materials.
3, different silencing effect
Noise insulation cotton has a silencing effect, sound-absorbing materials can be absorbed by the sound wave through the internal repeated consumption, the sound energy into thermal energy to consume the noise so as to achieve the purpose of noise reduction.
Acoustic panels, as the name suggests, are mainly soundproof, seek a certain degree of tightness, isolate all external noise, to ensure that the indoor environment is quiet. Acoustic panels are generally used in places with very high requirements for indoor acoustic environment. Acoustic panels and other soundproofing materials can block the propagation of noise sound waves, have done in the propagation pathway at the barrier to achieve the purpose of noise management muffling effect is very poor.
