Iimfuno zesantya somoya ezicocekileyo kunye nokutshintsha umoya

Umthamo owaneleyo wokungena komoya kukuhlambulula kwaye uphelise umoya ongcolisekileyo wangaphakathi, ngokweemfuno ezahlukeneyo zococeko, xaigumbi elicocekileyoukuphakama komnatha kuphezulu, ukwanda okufanelekileyo kwinani lotshintsho lomoya. Phakathi kwazo, umthamo wokungena komoya we-1 million wamagumbi acocekileyo athathwa ngokwenkqubo yokucoca ephezulu [7], kwaye ezinye ziqwalaselwa ngokwenkqubo yokucoca ephezulu. Xa i-100,000-class ecocekileyo igumbi lokucoca i-HEPA licwangciswe kwindawo ephakathi kwigumbi lomatshini okanye ekupheleni kwenkqubo, inani leenguqu zomoya linganyuswa ngokufanelekileyo nge-10-20%.

Ngexabiso elicetyiswayo elingentla lomthamo wokungena komoya, umbhali ukholelwa ukuba isantya somoya kwindawo yegumbi le-unidirectional.igumbi lokucoca elicocekileyoliphantsi, kwaye igumbi lokucoceka kwesiphithiphithi lixabiso elicetyiswayo elinombandela wokhuseleko olugcweleyo. I-Vertical unidirectional flow ≥0.25m / s, i-horizontal unidirectional flow ≥0.35m / s, kwimeko engenanto okanye ukubonwa kwe-static ukucoceka, nangona kunokufikelela kwiimfuno, kodwa amandla okuchasana nokungcoliseka ahluphekile, xa i-indoor ibe yindawo yokusebenza, ucoceko alunako ukuhlangabezana neemfuno, imizekelo enjalo ayifani; Kwangelo xesha, uthotho lwe-ventilator yaseTshayina alukayilungeli ngakumbi inkqubo yokucoca i-fan, umyili jikelele uhlala engabali ngokuchanekileyo ukuchasana komoya kwenkqubo, okanye akahoyanga ukuba umlandeli okhethiweyo ukwigophe lophawu lwendawo esebenza kakuhle, ukuze inkqubo iqalise ukusebenza kwakamsinya emva koko, umthamo womoya okanye isantya somoya asinakufikelela kwixabiso loyilo. Umgangatho we-United States Federal (FS209A ~ B) uchazwe ngoko ngaphambi ko-Oktobha 27, 1987: Isantya somoya segumbi elicocekileyo elingenanto ngokusebenzisa icandelo legumbi elicocekileyo lihlala ligcinwe kwi-9Oft / min (0.45m / s), kwaye phantsi kweemeko zokungaphazamisi kwigumbi lonke, ukufana kwesantya kungaphakathi kwe-± 20%. Nakuphi na ukuhla okubalulekileyo kwisantya sokuhamba komoya kwandisa amathuba okuba neziphumo zongcoliseko phakathi kwexesha lokuzicoca kunye nendawo yokusebenza (zonke iiparamitha ngaphandle koxinzelelo lothuli azichazwanga emva kokubhengezwa kweFS209C ngo-Oktobha 1987).

Kule njongo, umbhali ucinga ukuba kufanelekile ukunyusa ngokufanelekileyo ixabiso loyilo lwasekhaya lwangoku lwesantya sokuhamba kwe-unidirectional, iyunithi yethu kwiprojekthi yangempela ukwenza oko, umphumo ungcono. Uhlobo lwezidubedube igumbi elicocekileyo lixabiso elicetyiswayo elinokhuseleko olugcweleyo, kodwa abaqulunqi abaninzi abakaqinisekiswa ukuba xa besenza uyilo oluthile, inqanaba le-100,000 lokucoca igumbi lokungena umoya linyuswe libe ngama-20 ~ 25 amaxesha / h, inqanaba le-10,000 linyuswe ukuya kuma-30 ~ 40 amaxesha / h, kwaye inqanaba le-1000 linyuswa ukuya kumaxesha angama-1000, kwaye le nyusi ye-1000 inyuswa ukuya kwi-1000 ukuya kumaxesha angama-7 ukuya ku-7. utyalo-mali lokuqala. Kwakhona kwandisa iindleko zokugcinwa nokulawulwa kwexesha elizayo, kwaye akuyimfuneko ukwenza oko. Xa ulungiselela amanyathelo obugcisa bokucoca umoya waseTshayina [7], amagumbi acocekileyo asekhaya angaphezulu kwe-100 aphandwa kwaye alinganiswe, kwaye amagumbi amaninzi acocekileyo ayesavavanywa phantsi kweemeko eziguquguqukayo, kwaye iziphumo zibonise ukuba umthamo wokungena umoya we-100,000 grade ≥10 amaxesha / h, 10,000 grade ≥20 amaxesha / h, kunye ne-500 iimfuno zebakala / ≥0 kunye ne-100. Umgangatho we-United States federal (FS2O9A~B) uchaza ukuba igumbi elicocekileyo elingenalo unidirectional (iklasi ye-100,000, iklasi ye-10,000), ubude begumbi 8 ~ l2ft (2.44 ~ 3.66m), ngokuqhelekileyo qwalasela igumbi lonke ubuncinane kanye kwimizuzu emi-3 (oko kukuthi, amaxesha angama-20 / h). Ngoko ke, izibonelelo zenkcazo yoyilo [6] ithathele ingqalelo i-coefficient enkulu yobutyebi, kwaye umyili unokukhetha ngokukhuselekileyo ngokwexabiso elicetyiswayo lomthamo womoya.
