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, kwindawo engenanto okanye ubhaqo olumileyo lokucoceka, nangona lunokuhlangabezana neemfuno, kodwa amandla okuchasana nokungcoliseka akulunganga, xa sele ingaphakathi kwindawo yokusebenza. , ucoceko lusenokungafikeleli iimfuno, imizekelo enjalo ayingomntu ngamnye; Kwangelo xesha, uchungechunge lwe-ventilator yaseTshayina alukabikho lulungele ngakumbi inkqubo yokusulungekiswa kwefeni, umyili jikelele uhlala engabaleli ngokuchanekileyo ukuchasana komoya kwenkqubo, okanye akakhathaleli ukuba ngaba fan ekhethiweyo ikwi igophe lephawu lendawo yokusebenza ethandeka ngakumbi, ukuze inkqubo iqalise ukusebenza kwakamsinya emva koko, umthamo womoya okanye isantya somoya asinakufikelela kwixabiso loyilo. I-United States Federal standard (FS209A ~ B) ichazwe kakhulu ngaphambi ko-Oktobha 27, 1987: Isantya sokuhamba komoya segumbi elicocekileyo elingenandlela yonke ngokusebenzisa icandelo legumbi elicocekileyo lihlala ligcinwe kwi-9Oft / min (0.45m / s), kwaye phantsi kwemeko. kungabikho ukuphazamiseka 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 idizayini ethile, iqondo le-100,000 elicocekileyo legumbi lokungenisa umoya lilonyuswa libe ngama-20 ~ 25 amaxesha / h, inqanaba le-10,000 ukwanda ukuya kumaxesha angama-30 ~ 40 / h, kwaye inqanaba le-1000 linyuswe ukuya kumaxesha angama-60 ~ 70 / h, okungandisi kuphela amandla ezixhobo kunye nokwandisa 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 ezinamandla, kwaye iziphumo zabonisa ukuba umthamo wokuphefumla we-100,000 grade ≥10 amaxesha / h, I-10,000 grade ≥20 amaxesha / h, kunye ne-1000 ibakala ≥50 amaxesha / h inokuhlangabezana neemfuno. Umgangatho womanyano waseMelika (FS2O9A~B) umisela ukuba igumbi elicocekileyo elingena-unidirectional (iklasi ye-100,000, iklasi ye-10,000), ubude begumbi 8~l2ft (2.44 ~ 3.66m), ngokuqhelekileyo liqwalasela 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.
