【Specific embodiment】
The present invention is described in detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of supply air system of tall and big clean room of the present invention, including it is arranged on the return air at the top of toilet
Air channel 6 and supply air duct 9；Described supply air duct 9 is connected with ajutage 8, and is connected to toilet two by blowpipe 10
In the air blow and return passageway of side wall；Described return airway 6 is connected with backwind tube 7, and is connected to toilet two by return air branch pipe 5
In the air blow and return passageway of side wall；Air blow and return passageway includes air-supply passageway 4 and return air passageway 2, is provided with the inwall in passageway 4 of blowing
Jet air opening 3, is provided with individual layer grating return air inlet 1 on return air passageway 2, blowpipe 10 is connected with air-supply passageway 4, return air branch pipe
5 connect with return air passageway 2.
Jet air opening 3 and individual layer grating return air inlet 1 are arranged at the lower section of rail top 12 of toilet；And two air blow and return passageways
Upper corresponding jet air opening 3 and individual layer grating return air inlet 1 are oppositely arranged.Jet air opening 3 is sprayed using automatic wind direction angle-variable type
Stream air port, and come with filter；Two dispatch air ports are arranged in air blow and return passageway up and down, and lower exhaust outlet bottom is far from 5.2 meters of ground.Individual layer
The bottom of grating return air inlet 1 is far from ground 300mm.
Supply air duct 9, ajutage 8, blowpipe 10, return airway 6, backwind tube 7 and return air branch pipe 5 are arranged at cleaning
Between ceiling portion and furred ceiling 11.Control valve is provided with ajutage 8, blowpipe 10, backwind tube 7 and return air branch pipe 5.
As shown in Fig. 2 two air-supply passageways 4 are arranged side by side being integrally formed air-supply end with the interval of return air passageway 2；Integrally
Change air-supply end and air inlet, return air passageway 2 are set by being separated into independent seal cavity, the air-supply upper end of passageway 4 inside color steel
Upper end sets air outlet.
Embodiment
As shown in figure 3, tall and big clean room includes Liang Ge Precision Machinings area and two supply air systems, two supply air systems pair
The blowpipe and return air branch pipe answered are arranged in parallel.Precision Machining area temperature requirement：20 ± 2 DEG C, humidity requirement：45 ± 5%；It is clean
Cleanliness grade：100000 grades (N8).The space buildings area about 3300 ㎡, 8.75 meters of clear height under furred ceiling.Two fire prevention are divided in the region
Subregion, about 18 meters of each fire compartment clear span.
In order to ensure the humiture and purity requirements of workspace within 3 meters, now sent to blowing using both sides upper side, each side
With the mode of side bottom return air；Air outlet uses automatic wind direction angle-variable type jet air opening, tuyere bottom away from 5.2 meters of ground, up and down
Air outlet is put in two arrangements；Downside return air inlet bottom far from ground 300mm, using individual layer air grille.
By temperature sensor and the connection of control valve, the automatic accurate control of temperature is realized, by electromagnetism valve regulation
Air output and return air amount, indirectly adjust indoor temperature.When temperature exceed Precision Machining area temperature requirement when, increase air output and
Return air amount is quickly reduced temperature, and when temperature is less than Precision Machining area temperature requirement, reducing air output and return air amount is carried out
Rise high-temperature.
Principle of the invention is as follows：
1. in order to realize that (cleaniliness classs N8, temperature accuracy controls ± 2 for the cleaning and constant temperature and humidity requirement of large space
DEG C, humidity precision controlling ± 5%), it is necessary in control room dust and laying dust possibility, if air-conditioning sends wind pipeline back to directly entered
Enter clean area air blow and return, or be positioned in clean furred ceiling, through long-play after, will certainly aggravate indoor circulation air be contaminated
Possibility, internal cause greatly increases.
2. the area of tall and big clean room is generally large, makes full use of ceiling advantage, reduces air output, and preferably control is real
The cleanliness factor of area or operating space is tested, now takes following manner to arrange air supply duct and end：
(1) air blow and return supervisor is arranged in furred ceiling, and branch wind pipe is separated from air main and is followed by integration air-supply end；
(2) the concrete-cored color steel air-supply end of 50mm thickness, integrated purifying is each independent by building span, is separated into inside it
Three parts.Two vertical ends of left and right are air-supply passageways 4, and using top Lateral supply, long-range air outlet is directly arranged in air-supply passageway surface,
And untill passageway passes to air outlet bottom；Integrated end intermediate vertical region is return air passageway 2, bottom is led directly to, away from ground
Return air inlet is set at 300mm in return air passageway surface.Overall air-supply end is separated by color steel inside, is connect there is no airduct
Enter, make to send wind pipeline back to and send air port integration back to, integral manufacturing while reducing inleakage, it is ensured that Cleanliness, subtracts
Lack during airduct makes convergence process and brought possible secondary pollution in the future, also made that overall clean area is more attractive in appearance, stringing is simpler
Clean convenience.
More than, only presently preferred embodiments of the present invention is not limited only to practical range of the invention, all according to patent of the present invention
Equivalence changes and modification that the content of scope is done, all should be technology category of the invention.
