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 okuqondile okuqondile okungaqondile ≥0.25m/s, ukugeleza kwe-unidirectional okuvundlile ≥0.35m/s, kusimo esingenalutho noma ukutholwa kwenhlanzeko okumile, nakuba kungahlangabezana nezimfuneko, kodwa ikhono lokuvimba ukungcoliswa liphansi, uma sekungaphakathi endlini kusimo sokusebenza. , inhlanzeko ingase ingahlangabezani nezimfuneko, izibonelo ezinjalo azizona zodwa; Ngasikhathi sinye, uchungechunge lwe-ventilator yaseChina alukafaneleka kakhulu ohlelweni lokuhlanza lwe-fan, umklami ojwayelekile ngokuvamile akabali ngokunembile ukumelana komoya kwesistimu, noma akanaki ukuthi fan ekhethiwe iku- ijika lesici lendawo yokusebenza evumayo, ukuze uhlelo luqale ukusebenza maduze nje, umthamo womoya noma isivinini somoya awukwazi ukufinyelela inani lokuklama. Izinga le-United States Federal (FS209A~B) liye lashiwo ngaphambi komhla zingama-27 kuMfumfu, 1987: Isivinini sokugeleza komoya segumbi elihlanzekile elingenandawo yonke ngokusebenzisa ingxenye yegumbi elihlanzekile livamise ukugcinwa ku-9Oft/min(0.45m/s), nangaphansi kwesimo. ngaphandle kokuphazamiseka ekamelweni lonke, ukufana kwejubane kungaphakathi ± 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 lweziyaluyalu liyinani elinconyiwe elinesici sokuphepha esigcwele, kodwa abaklami abaningi abakaqinisekiswa ukuthi uma benza idizayini ethile, izinga lezinga elingu-100,000 levolumu yokungenisa komoya yegumbi elihlanzekile liyakhuphuka libe izikhathi ezingu-20~25/h, izinga elingu-10,000 lenyuke laya ku-30 ​​~ 40 izikhathi / h, futhi izinga le-1000 lenyuka laya ku-60 ~ 70 izikhathi / h, okungagcini nje ukwandisa umthamo wemishini futhi kwandise ukutshalwa kwezimali kokuqala. Futhi kwandisa izindleko zokugcinwa nokuphathwa kwesikhathi esizayo, futhi akudingekile ukwenza kanjalo. Lapho kulungiswa izindlela zobuchwepheshe zaseChina zokuhlanza umoya [7], kwaphenywa futhi kwalinganiswa amakamelo ahlanzekile asekhaya angaphezu kwe-100, futhi amakamelo amaningi ahlanzekile ayesahlolwa ngaphansi kwezimo eziguquguqukayo, futhi imiphumela yabonisa ukuthi umthamo wokungenisa umoya we-100,000 grade ≥10 izikhathi / h, 10,000 grade ≥20 izikhathi / h, futhi 1000 grade ≥50 izikhathi / h kungahlangabezana nezidingo. 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.
