Abstract
A kind of blower fan group damping noise reduction construction method belongs to passive room technical field of construction.Construction procedure are as follows: blower hanging, installation blower and being flexible coupling of main air hose, outdoor unit installation increase damping cushion.Advantage is, prevent Fresh air handling units noise exceeded, guarantee less than 20 decibels index requests of energy saving building and passive room indoor environment noise objective, using spring hanger link hangs new blower, increases new blower and main air hose is flexible coupling, increases outdoor unit Rubber shock-absorbing pad, lower the noise of Fresh air handling units generation significantly, play the quiet comfortable good result of indoor living environment, construction is simple, and labor intensity is low, and material consumption is small, small investment, effect are good.
Description
Technical field
The invention belongs to passive room technical field of construction, in particular to a kind of blower fan group damping noise reduction construction method, blower
Group or energy environment unit or air-conditioning, which reduce vibration, reduces noise, and using spring shock absorption principle, equipment hoisting is used with spring
Sunpender reduces vibration amplitude when equipment starts, to reduce noise；When outdoor unit is placed on outdoor bracket, in outdoor unit
Upper patent yielding rubber pad is padded between bracket, outdoor vibration is reduced, to reduce noise；Fresh air handling units air port and ventilation duct
Road is connected to be flexible coupling using the double-layer aluminum-foil with heat preservation, prevents solid-borne sound transmission；Fresh air suitable for passive room and energy saving building
Unit damping noise reduction construction, while being also applied for the damping noise reduction construction of common building air-conditioner outdoor unit.
Background technique
In passive room engineering construction, for a home from home for reaching inhabitation, room noise control is very strict, wherein indoor
The noise that Fresh air handling units generate is the main element in room noise source.How to solve what Fresh air handling units were generated by operation vibration
Noise problem brings new issue to construction technical staff, this needs to guarantee the normal work of Fresh air handling units, also to solve new
Vibration amplitude reduces problem when blower fan group equipment is run.
Previous Fresh air handling units do not consider damping requirement when installing, unit is directly connected to when lifting with sunpender, and unit goes out
Air port is using air hose directly with main air hose Hard link, and outdoor unit is directly bolted with bracket, and the noise of generation is larger.The present invention
It is mainly improved on the basis of conventional mounting mode, in units' installation, sunpender and unit use spring to carry out plating, make
Vibration is cut down by spring when unit is run；Unit uses the double-layer aluminum-foil with heat preservation to be flexible coupling with main air hose simultaneously, hinders
The unit that broken shakes noise and is transmitted to main air hose by Hard link, is not delivered to each room using noise, ensure that inhabitation room
Peace and quiet；The noise of outdoor unit, which is used, increases special (purpose) rubber resilient cushion in outdoor unit and bearing attachment position, reduces outdoor unit shake
Dynamic amplitude reduces vibration noise.
By increasing spring hanger link to Fresh air handling units, increasing being flexible coupling of unit and main air hose, increase outdoor unit rubber and subtract
Shake pad, the noise for generating Fresh air handling units lower significantly, play the quiet comfortable good result of indoor living environment, construction letter
Easily, the advantages that labor intensity is low, and material consumption is small, small investment, and effect is good.
Summary of the invention
The purpose of the present invention is to provide a kind of blower fan group damping noise reduction construction methods, prevent Fresh air handling units noise exceeded,
Guarantee less than 20 decibels index requests of energy saving building and passive room indoor environment noise objective.
Construction procedure of the invention is as follows:
(1) blower is hung:
Using the hanger erection blower with spring arrangement, using 4 sunpender hangings on top plate, 4 sunpenders are blower
Sunpender with spring arrangement；
(2) installation blower and main air hose are flexible coupling:
Fan outlet is connect with main air hose to be flexible coupling using the double-layer aluminum-foil with heat preservation, prevents solid-borne sound transmission；
(3) outdoor unit installation increases damping cushion:
Outdoor unit is mounted on outdoor bracket, is increased Rubber shock-absorbing pad in bracket and outdoor unit connecting portion, is reduced vibration
Amplitude, to reduce vibration noise.
It is an advantage of the current invention that hanging new blower using spring hanger link, increasing being flexible coupling of new blower and main air hose, increase
Add outdoor unit Rubber shock-absorbing pad, the noise for generating Fresh air handling units lowers significantly, and it is quiet comfortable good to play indoor living environment
Good effect, construction is simple, and labor intensity is low, and material consumption is small, small investment, and effect is good.

Specific embodiment
Illustrate embodiment of the present invention with reference to the accompanying drawing:
(1) new blower hanging:
Blower 2 is installed using the sunpender 1 with spring arrangement, for blower 2 using 4 sunpender hangings on top plate, 4 sunpenders are equal
For the sunpender with spring vibration damper；
(2) installation blower and main air hose are flexible coupling:
2 air outlet of blower is connect with main air hose is flexible coupling 5 using the double-layer aluminum-foil that band is kept the temperature, and prevents solid-borne sound transmission；
(3) outdoor unit installation increases damping cushion:
Outdoor unit 4 is mounted on outdoor bracket, is increased special (purpose) rubber resilient cushion 3 in bracket and outdoor unit connecting portion, is subtracted
Few vibration amplitude reduces vibration noise.
Claims (1)
