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, kuwonjezereka 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. Oima unidirectional otaya ≥0.25m/s, yopingasa unidirectional otaya ≥0.35m/s, mu malo opanda kanthu kapena malo amodzi kuzindikira ukhondo, ngakhale akhoza kukwaniritsa zofunika, koma odana ndi kuipitsa mphamvu ndi osauka, kamodzi m'nyumba mu ntchito boma. , ukhondo sungathe kukwaniritsa zofunikira, zitsanzo zoterezi siziri payekha; Nthawi yomweyo, mndandanda wazolowera mpweya waku China sunakhale woyenera kwambiri pamayendedwe oyeretsera mafani, wopanga wamkulu nthawi zambiri samawerengera molondola kukana kwa mpweya, kapena salabadira ngati fan yosankhidwayo ili mu Khalidwe lopindika la malo abwino kwambiri ogwirira ntchito, kuti dongosolo lizigwira ntchito posachedwa, voliyumu ya mpweya kapena liwiro la mphepo silingafikire mtengo wake. 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 motere popanda kusokoneza m'chipinda chonse, kufanana kwa liwiro kuli mkati mwa ± 20%. Kutsika kulikonse kwa liwiro lakuyenda kwa mpweya kumawonjezera mwayi wa kuipitsidwa pakati pa nthawi yodzitsuka ndi malo ogwirira ntchito (zonse kupatula ndende ya 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 sadatsimikizebe kuti popanga mapangidwe enieni, kuchuluka kwa mpweya wabwino wa 100,000 kuchipinda kumawonjezeka mpaka 20 ~ 25 nthawi / h, mulingo wa 10,000 ndi kuchuluka kwa 30 ~ 40 nthawi / h, ndipo mulingo wa 1000 ukuwonjezeka mpaka 60 ~ 70 nthawi / h, zomwe sizimangowonjezera mphamvu ya zida ndikuwonjezera. ndalama zoyamba. Zimawonjezeranso mtengo wokonza ndi kuyang'anira mtsogolo, ndipo sikofunikira kutero. Pokonzekera miyeso yaukadaulo yaku China yoyeretsa mpweya [7], zipinda zopitilira 100 zoyera zidafufuzidwa ndikuyesedwa, ndipo zipinda zambiri zoyera zidayesedwabe pansi pazikhalidwe zamphamvu, ndipo zotsatira zake zidawonetsa kuti mpweya wabwino wa 100,000 grade ≥10 times / h, 10,000 kalasi ≥20 nthawi / h, ndi 1000 kalasi ≥50 nthawi / h akhoza kukwaniritsa zofunika. Muyezo wa federal ku United States (FS2O9A~B) umanena kuti 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 chonsecho kamodzi mphindi zitatu zilizonse ( ndiye kuti, 20 nthawi / h). Chifukwa chake, zomwe zimaperekedwa ndi kapangidwe kake [6] zatenganso gawo lalikulu lazachuma, ndipo wopanga amatha kusankha motetezeka malinga ndi kuchuluka kwa mpweya wabwino.
