Description
Technical field
This utility model relates to a kind of air-conditioning technical field, reaches the environmental protection and energy saving of NC35 particularly to a kind of noise level
Supply air system.
Background technology
For ensureing health and the use function of building, the high noise levels to difference building defined, is building
Environmental noise abatement and the foundation of room acoustical design.And NC is the noise rating index that Unite States Standard is recommended.Nineteen fifty-seven is by vain
One group of noise criteria curve that auspicious nanogram proposes, as the baseline values of indoor noise standard, it is adaptable to steady state noise.Same song
On line, the noise of each octave is it is believed that have the interference of same degree.
NC35 changes our the usual decibel (equivalent A-weighted sound pressure level) said into and is approximately 40dB.In standard for acoustic environmental quality, 40dB is also
Be exactly NC35 refer to residential block, hospital, school, scientific research institution, administration building etc. be major function area (these all
It is to need the region kept quite) noise level limit at night.
Along with the fast development of building industry, near building and internally installed increasing electromechanical facility, such as electricity
Ladder, transformator, water pump, handpiece Water Chilling Units, cooling tower etc., but vibration and noise that these equipment produce in running are main
It is passed directly to Indoor environment by building structure, also has through air or door and window incoming, cause in indoor office and residence
The severe jamming of the people lived, we are just referred to as indoor noise environment pollution for these.People tackle indoor noise environment pollution at present
Typically take following several measure: one is to increase tubulature type cylinder full range deafener or quiet design when in airduct
Pressure case, also has and exactly machine room is arranged on from office or residence area remote position, then to have a kind of be by sky bigger for air quantity
Gas disposal unit design become multiple little air quantity unit dispersion place, but this several ways have need increase machine room, or
Increase airduct etc., can cause wasting material, not be inconsistent with the energy-conserving and environment-protective advocated now.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of noise level reach NC35 environmental protection and energy saving air-supply system
System.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of noise level reaches the environmental protection of NC35
Energy-saving blowing system, its innovative point is: includes casing A and casing B that upper and lower superposition arranges, sets gradually in described casing A
Wind inlet section, air intake fillter section and coil section, be provided with an inlet side tubulature type cylinder full range deafener, institute in described wind inlet section
Being provided with the cylindrical straight that axis arranges along wind direction in stating coil section comprehensively to manage, described cylindrical straight overall pipe one end is provided with one
Bypass air-valve A, is provided with ventilation valve B on one side, sets gradually fan section and send in this casing B between described casing B and casing A
Wind section, described air supply section is provided with an air side tubulature type cylinder full range deafener.
Further, described bypass air-valve B connects coil section and the fan section of casing B of casing A.
Further, described air intake fillter section includes that the roughing efficiency air filter set gradually and middle effect electrostatic ozone free stay electricity
Pole dust removal filter.
Further, described fillter section, coil section, fan section and air supply section correspondence position are respectively provided with maintenance door.
Further, described air supply section is additionally provided with a blower fan homogenizing plate.
The utility model has the advantage of:
(1) mentality of designing of sound pollution in traditional process chamber is changed, it is provided that a kind of novel functional section series connection air-supply
System.By the analysis of acoustic environment and conditioning in Transition Season operating mode is contrasted, with reach the optimized control of indoor NC35 noise level with
And minimumization of equipment operation energy consumption, combine with environmental protection, saving material etc. simultaneously.
(2) new indoor low noise supply air system uses up-down structure, under two kinds of different operating modes of air-conditioning season and conditioning in Transition Season
Air-flow is all by inlet side tubulature type cylinder full range deafener and the air side tubulature type cylinder dual noise reduction of full range deafener, significantly
Reducing the noise in unit so that room noise of entering after air-treatment also reduces a lot, 36000 m3/h, outlet is remaining quiet
No matter airduct air outlet noise less than 55 decibels, and can instead of the pipe row being previously installed in airduct to the unit of pressure 600Pa
Formula cylinder full range deafener and plenum chamber, decrease the most unnecessary equipment taken up room.
(3) this supply air system can also effective material-saving, airduct multi-stage silencer can be cancelled, outside engine noise can as little as 52
Decibel, can cancel machine room wallboard and eliminate the noise.Airduct overbottom pressure about 400Pa can also be effectively reduced so that the unit air volume wasted work in air channel
Rate is from original 0.28W/(m3/h) it is reduced to 0.22 W/(m3/h), improve about 15%.
(4) energy-saving effect of this supply air system is it is also obvious that according to air quantity 20000 m3/h, Margin blast pressure 350Pa, total head
900Pa, owing to transition season downstream tissue is without hot and cold water coil pipe, in being allowed to machine, crushing can reduce 400Pa, so
Total head also can reduce, and unit air volume wasted work rate also can reduce, and reaches energy-conservation purpose.According to different air force specifications, energy-conservation
Scope is between 25-50%.
(5) this system also had air filtering function, roughing efficiency air filter and middle effect electrostatic precipitation filter and can reach
Pollution except PM2.5 so that new wind preferably can enter indoor through process.
