Konzani liwiro la mphepo m'chipinda ndi kusintha kwa mpweya

Kukwanira kwa mpweya wabwino ndikuchepetsa ndikuchotsa mpweya woipitsidwa wamkati, malinga ndi zofunikira zaukhondo,chipinda choyerakutalika kwa ukonde ndikokwera, kuwonjezeka koyenera kwa chiwerengero cha kusintha kwa mpweya. Pakati pawo, kuchuluka kwa mpweya wa zipinda zoyera 1 miliyoni kumaganiziridwa molingana ndi njira yoyeretsera bwino kwambiri [7], ndipo zina zonse zimaganiziridwa molingana ndi njira yoyeretsera kwambiri. Pamene fyuluta yoyera ya 100,000 ya chipinda cha HEPA imakonzedwa pakati pa chipinda cha makina kapena mapeto a dongosolo, chiwerengero cha kusintha kwa mpweya chikhoza kuwonjezeka moyenerera ndi 10-20%.

Pa mtengo womwe waperekedwa pamwambapa wa voliyumu ya mpweya wabwino, wolemba amakhulupirira kuti mphepo imathamanga kudutsa gawo la chipinda cha unidirectional.chipinda choyerandi otsika, ndipo chipinda choyera cha chipwirikiti ndiye mtengo wovomerezeka wokhala ndi chitetezo chokwanira. Otsika unidirectional otaya ≥0.25m / s, yopingasa unidirectional otaya ≥0.35m/s, mu dziko chopanda kanthu kapena static kuzindikira ukhondo, ngakhale akhoza kukwaniritsa zofunika, koma odana ndi kuipitsidwa mphamvu ndi osauka, kamodzi m'nyumba mu dziko ntchito, ukhondo sangakwaniritse zofunika, zitsanzo zimenezi si munthu; Nthawi yomweyo, mndandanda wa makina opangira mpweya waku China sunakhale woyenera kwambiri pakuyeretsa fani, wopanga wamkulu nthawi zambiri samawerengera molondola kukana kwa mpweya wa dongosolo, kapena salabadira ngati fan yosankhidwayo ili pamakhota a malo abwino kwambiri ogwirira ntchito, kotero kuti dongosololi liyamba kugwira ntchito posakhalitsa, voliyumu ya mpweya kapena liwiro la mphepo silingafike pamtengo wopanga. Muyezo wa United States Federal (FS209A ~ B) udanenedwa pasanafike pa Okutobala 27, 1987: Kuthamanga kwa mpweya kwa chipinda choyera cha unidirectional kudzera m'chipinda choyera nthawi zambiri kumasungidwa pa 9Oft/min(0.45m/s), ndipo ngati palibe kusokonezedwa mchipinda chonsecho, liwiro lofanana limakhala mkati mwa ± 20%. Kutsika kulikonse kwa liwiro lakuyenda kwa mpweya kumawonjezera mwayi wa kuipitsidwa pakati pa nthawi yodzitsuka ndi malo ogwirira ntchito (zonse kupatula kuchuluka kwa fumbi sizinatchulidwe pambuyo pa kulengeza kwa FS209C mu Okutobala 1987).

Kuti izi zitheke, wolemba akuganiza kuti ndi koyenera kuti awonjezere mtengo wamakono wamakono wamakono a unidirectional otaya liwiro, gawo lathu mu polojekiti yeniyeni kutero, zotsatira zake zimakhala bwino. Chipinda choyera chamtundu wa chipwirikiti ndi mtengo wovomerezeka wokhala ndi chitetezo chokwanira, koma opanga ambiri sakutsimikiziridwa kuti popanga mapangidwe enieni, kuchuluka kwa mpweya wabwino wa 100,000 mu chipinda choyera kumachulukitsidwa mpaka 20 ~ 25 nthawi / h, mulingo wa 10,000 ukuwonjezeka mpaka 30 ~ 40 nthawi / h, ndipo 10000000 / h imawonjezera kuchuluka kwa 1000 / h, komanso kuchuluka kwa zida za 1000 / h, zomwe zimangowonjezera nthawi / 1000 mpaka 7. ndalama zoyamba. Zimawonjezeranso mtengo wokonza ndi kuyang'anira mtsogolo, ndipo sikofunikira kutero. Pokonzekera miyeso yaukadaulo yaku China yotsuka mpweya [7], zipinda zopitilira 100 zoyera zidafufuzidwa ndikuyezedwa, ndipo zipinda zambiri zoyera zidayesedwabe pansi pazikhalidwe zamphamvu, ndipo zotsatira zake zidawonetsa kuti mpweya wabwino wa 100,000 kalasi ≥10 nthawi / h, 10,000 kalasi ≥20 nthawi / h, ndi 100 grade 0 / h, ndi 100 grade 0. United States federal standard (FS2O9A~B) imati chipinda choyera chopanda unidirectional (kalasi ya 100,000, kalasi ya 10,000), kutalika kwa chipinda 8 ~ l2ft (2.44 ~ 3.66m), nthawi zambiri amalingalira chipinda chonse kamodzi mphindi 3 zilizonse (ndiko kuti, nthawi 20 / h). Chifukwa chake, zomwe zimaperekedwa ndi kapangidwe kake [6] zatenganso gawo lalikulu lazachuma, ndipo wopanga amatha kusankha motetezeka malinga ndi kuchuluka kwa mpweya wabwino.
