Izidingo zesivinini somoya zegumbi elihlanzekile kanye nezinguquko zomoya

Umthamo wokungena komoya owanele uwukuncibilikisa nokuqeda umoya ongcolile wasendlini, ngokuya ngezidingo ezihlukene zokuhlanzeka, laphoigumbi elihlanzekileukuphakama kwenetha kuphakeme, ukwanda okufanele kwenani lezinguquko zomoya. Phakathi kwazo, umthamo wokungenisa umoya wamakamelo ahlanzekile ayisigidi ubhekwa ngokohlelo lokuhlanza olusebenza kahle kakhulu [7], kanti okunye kubhekwa ngokuhambisana nesistimu yokuhlanza esebenza kahle kakhulu. Lapho isihlungi se-HEPA segumbi elihlanzekile lekilasi elingu-100,000 sihlelwe endaweni eyodwa ekamelweni lomshini noma ekupheleni kwesistimu, inani lezinguquko zomoya lingakhuphuka ngokufanele ngo-10-20%.

Ngevelu enconyiwe engenhla yevolumu yokungenisa umoya, umbhali ukholelwa ukuthi isivinini somoya esigabeni segumbi lendawo yonke.geleza igumbi elihlanzekileliphansi, futhi igumbi elihlanzekile elineziyaluyalu yinani elinconyiwe elinesici sokuphepha esigcwele. Ukugeleza kwe-unidirectional okume mpo ≥0.25m/s, ukugeleza kwe-unidirectional okuvundlile ≥0.35m/s, esimweni esingenalutho noma ukutholwa kwenhlanzeko okumile, nakuba kungahlangabezana nezidingo, kodwa ikhono lokulwa nokungcola liphansi, uma ingaphakathi lingena esimweni sokusebenza, ukuhlanzeka kungase kungahlangabezani nezidingo, izibonelo ezinjalo azizona zodwa; Ngasikhathi sinye, uchungechunge lwe-ventilator yaseChina alukafaneleka kakhulu ohlelweni lokuhlanza lwe-fan, umklami ojwayelekile ngokuvamile akabali ngokunembile ukumelana komoya kohlelo, noma akanaki ukuthi fan ekhethiwe ikujika lesici sendawo yokusebenza evumayo, ukuze uhlelo luqale ukusebenza maduze nje, ivolumu yomoya noma isivinini somoya asikwazi ukufinyelela inani lokuklama. Izinga le-United States Federal (FS209A~B) liye lashiwo ngaphambi komhla zingama-27 kuMfumfu, 1987: Isivinini sokugeleza komoya segumbi elihlanzekile elingaqondile ngokusebenzisa ingxenye yegumbi elihlanzekile livamise ukugcinwa ku-9Oft/min(0.45m/s), futhi ngaphansi kwesimo sokungaphazanyiswa kwegumbi lonke, ukufana kwejubane kungaphakathi kuka-±20%. Noma yikuphi ukwehla okuphawulekayo kwesivinini sokugeleza komoya kwandisa amathuba okuba nemiphumela yokungcola phakathi kwesikhathi sokuzihlanza kanye nendawo yokusebenza (yonke imingcele ngaphandle kokugcwala kothuli ayicaciswanga ngemva kokumenyezelwa kwe-FS209C ngo-Okthoba 1987).

Kuze kube manje, umbhali ucabanga ukuthi kufanelekile ukukhulisa ngokufanelekile inani lamanje lokuklama kwasekhaya kwejubane lokugeleza kwe-unidirectional, iyunithi yethu kuphrojekthi yangempela yokwenza kanjalo, umphumela ungcono. Igumbi elihlanzekile lohlobo lwezinxushunxushu liyinani elinconyiwe elinesici sokuphepha esigcwele, kepha abaklami abaningi abakaqinisekiswa ukuthi lapho benza umklamo othize, umthamo wokungenisa umoya wegumbi elihlanzekile lezinga le-100,000 ukhushulwa ube izikhathi ezingama-20 ~ 25 / h, izinga le-10,000 lenyuswa libe izikhathi ezingama-30 ~ 40 / h, futhi izinga le-1000h elikhushulwa izikhathi eziyi-1000, hhayi kuphela izinga le-1000 / 7 elikhuphula izinga lokukhuphuka liye ku-7 utshalomali lokuqala. Futhi kwandisa izindleko zokugcinwa nokuphathwa kwesikhathi esizayo, futhi akudingekile ukwenza kanjalo. Lapho kulungiselelwa izindlela zobuchwepheshe zaseChina zokuhlanza umoya [7], kwaphenywa futhi kwalinganiswa amakamelo ahlanzekile asekhaya angaphezu kuka-100, futhi amakamelo amaningi ahlanzekile ayesahlolwa ngaphansi kwezimo eziguquguqukayo, futhi imiphumela yabonisa ukuthi umthamo wokungenisa umoya webanga le-100,000 ≥10 izikhathi / ihora, i-10,000 ibanga ≥20 izikhathi / ihora, futhi izikhathi ezingu-5 zingahlangabezana nezidingo zebanga / ≥0 izikhathi ezingu-100. Izinga lombuso lase-United States (FS2O9A~B) libeka ukuthi igumbi elihlanzekile lokugeleza okungelona okukodwa (ikilasi elingu-100,000, ikilasi elingu-10,000), ubude begumbi 8~l2ft(2.44~3.66m), ngokuvamile licabangela igumbi lonke okungenani kanye njalo emizuzwini emi-3 (okungukuthi, izikhathi ezingu-20/h). Ngakho-ke, izinhlinzeko zokucaciswa kokuklama [6] ziye zacabangela i-coefficient yokuceba enkulu, futhi umklami angakhetha ngokuphephile ngokuvumelana nenani elinconywayo levolumu yokungenisa umoya.
