[specific embodiment]
The present invention is described in detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of supply air system of tall and big clean room of the present invention, including the return air at the top of toilet is arranged in
Air duct 6 and supply air duct 9；The supply air duct 9 is connected to air supply tube 8, and is connected to toilet two by blowpipe 10
In the air blow and return passageway of side wall；The return airway 6 is connect 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 on the inner wall in passageway 4 of blowing
Jet air opening 3 is provided with single layer grating return air inlet 1 on return air passageway 2, and blowpipe 10 is connected to air-supply passageway 4, return air branch pipe
5 are connected to return air passageway 2.
Jet air opening 3 and single layer grating return air inlet 1 are arranged at 12 lower section of rail top of toilet；And two air blow and return passageways
Upper corresponding jet air opening 3 and single layer grating return air inlet 1 are oppositely arranged.Jet air opening 3 is sprayed using automatic wind direction angle-variable type
Air port is flowed, and comes with filter；Two rows of air outlets, 5.2 meters far from ground of lower exhaust outlet bottom are arranged in air blow and return passageway up and down.Single layer
1 bottom of grating return air inlet is far from ground 300mm.
Supply air duct 9, air supply tube 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 on air supply tube 8, blowpipe 10, backwind tube 7 and return air branch pipe 5.
As shown in Fig. 2, two air-supply passageways 4 are spaced with return air passageway 2 is arranged side by side being integrally formed air-supply end；One
Change air-supply end and air inlet, return air passageway 2 are set by being separated into independent seal cavity, air-supply 4 upper end of passageway inside color steel plate
Air outlet is arranged in upper end.
Embodiment
As shown in figure 3, tall and big clean room includes Liang Ge Precision Machining 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: 100,000 grades (N8).About 3300 ㎡ of the space buildings area, 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 guarantee the temperature and humidity and purity requirements of workspace within 3 meters, now sent using both sides upper side to blowing, each side
With the mode of side bottom return air；Air outlet use automatic wind direction angle-variable type jet air opening, 5.2 meters away from ground of tuyere bottom, up and down
Two rows arrangement air outlet；Downside return air inlet bottom is far from ground 300mm, using single layer air grille.
By the connection of temperature sensor and control valve, the automatic accurate control of temperature is realized, electromagnetism valve regulation is passed through
Air output and return air amount, indirectly adjust room temperature.When temperature be more than Precision Machining area temperature requirement when, increase air output and
Return air amount carries out quickly reducing temperature, when temperature is lower than Precision Machining area temperature requirement, reduces air output and return air amount carries out
Increase temperature.
The principle of the present invention is as follows:
1. in order to realize the cleaning and constant temperature and humidity requirement (cleaniliness classs N8, temperature accuracy control ± 2 of large space
DEG C, humidity precision controlling ± 5%), a possibility that needing dust and dust accumulation in control room, if air-conditioning send back to air piping directly into
Enter clean area air blow and return, or be placed in clean furred ceiling, after through a long time operation, it is contaminated that indoor circulation air will certainly be aggravated
A possibility that, internal cause greatly increases.
2. the area of tall and big clean room is generally large, ceiling advantage is made full use of, reduces air output, preferably control is real
The cleanliness of area or operating space is tested, under type such as is now taken 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 main air hose is followed by integration end of blowing；
(2) 50mm is thick, the concrete-cored color steel plate air-supply end of integrated purifying is respectively independent by building span, inside be separated into
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 until passageway passes to air outlet lower part；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.Whole air-supply end is by color steel plate inner part every there is no air hoses to connect
Enter, make to send air piping back to and send air port integration back to, integral manufacturing ensure that Cleanliness, subtract while reducing inleakage
Lack in air hose production convergence process and brought possible secondary pollution in the future, has also made whole clean area more beautiful, 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 the invention patent
The equivalence changes and modification that the content of range is done all should be technology scope of the invention.
