Ndi chizolowezi chofala kugwiritsa ntchito mpweya wozungulira kuti uziziritse nkhuku nthawi yotentha yachilimwe. Pa ulimi wa mazira wambiri, liwiro la mphepo m'nyumbakhola la nkhukuiyenera kufika osachepera 3m/s, ndipo liwiro la mphepo m'nyumba ya nkhuku m'malo otentha kwambiri komanso okhala ndi chinyezi chambiri liyenera kufika kuposa 4m/s kuti ikhale ndi "mphamvu yabwino yoziziritsira mphepo".
"Kuziziritsa kwa mphepo" makamaka kumatanthauza liwiro la mphepo kuti ichepetse kutentha kwa thupi la nkhuku.
Kodi liwiro la mphepo lingathandize bwanji kutentha kwa thupi la nkhuku?
"Malinga ndi kafukufuku wa University of Georgia, liwiro la mphepo linakwera kuchoka pa 0m/s kufika pa 2.54m/s. Kutentha kwa thupi la nkhuku kudzatsika ndi madigiri oposa 6."°C.
Kuti ndipeze liwiro lalikulu la mphepo, chizolowezi changa chachizolowezi ndi kupanganyumba ya nkhukudenga, chepetsani kutalika kwa khola la nkhuku, kapena kuchokera pamwamba pa khola la nkhuku motsatira denga lamakona atatu molunjika pansi mtunda uliwonse kuti muyike chotchingira mphepo kapena nsalu yotchingira mphepo kuti muchepetse malo opingasa a khola la nkhuku kuti muwongolere liwiro la mphepo m'khola.
Chifukwa chiyani mukuchita izi, makamaka chifukwa liwiro la mphepo limagwirizana kwambiri ndi dera lodutsa lakhola la nkhuku.
Kuwerengera liwiro la mphepo mu khola la nkhuku lokhala ndi mpweya wokwanira kwa nthawi yayitali: liwiro la mphepo = kuchuluka kwa mpweya wokwanira / dera lozungulira khola
Kuchokera mu njira iyi, n'zoonekeratu kuti kuti muwonjezere liwiro la mphepo ya khola, mwina muwonjezere mpweya wa khola, mwachitsanzo, kuwonjezera chiwerengero cha mafani osagwedezeka ndi mpweya, kapena kuchepetsa malo ozungulira khola.
Kuchulukitsa mafani kumatanthauza kuonjezera ndalama, kuonjezera kugwiritsa ntchito magetsi, kuonjezera ndalama zokonzera, ndipo pamapeto pake kuwonjezera ndalama zogwirira ntchito ku bizinesi.
Kenako, kuwonjezera liwiro la mphepo kuyenera kuganiziridwa pochepetsa dera lopingasa lakhola la nkhukuPansipa tikumvetsa kusintha kwa khola la nkhuku isanayambe komanso itatha kuwonjezera nsalu yotchinga mphepo pogwiritsa ntchito mawerengedwe enieni.
Mwachitsanzo: khola la nkhuku la mamita 12 m'lifupi, mamita 100 m'litali, makoma am'mbali a khola ndi 2.4 m'litali, pakati pa khola (lalikulu kwambiri) ndi mamita 4.8, kholalo lili ndi mafani 10 a mainchesi 50, mphamvu yopumira mpweya ya fani iliyonse pa -50 Pa ndi mamita 31000³/h.
Kenako liwiro la mphepo ya khola la nkhuku liyenera kukhala: liwiro la mphepo = kuchuluka kwa mpweya / malo odutsa = 31000 / 3600× 10 / [12]× (4.8 + 2.4) / 2] = 86.1/43.2 = 1.99m/s
Ngati tiyika nsalu yotchinga padenga kapena yotchinga mphepo m'khola la nkhuku, kotero kuti kutalika kwa pamwamba pa khola kapena m'mphepete mwa nsalu kuchokera pansi ndi 3.6m, ndipo kutalika kwa mbali zonse ziwiri za khola sikunasinthe, liwiro la mphepo ndi = 31000/3600×10/[12]×(3.6+2.4)/2]=86.1/36=2.39m/s
Chifukwa chake, ngati pali mafani ofanana, pochepetsa malo otsetsereka a nyumba ya nkhuku, kuthamanga kwa mphepo kumatha kukwera pa 0.4m/s yoyambirira, kutanthauza kuti, mphamvu ya mphepo yawonjezeka ndi 20%, kusintha kwa liwiro la mphepo komwe kumachitika chifukwa cha kuzizira kwa mphepo nakonso kumasiyana, kusiyana pakati pa kuzizira kwa mphepo ziwiri komwe kumagwirizana ndi kutentha kwa pafupifupi madigiri 2.℃, pakakhala kutentha kwakukulu, kusiyana kwa kutentha kwa madigiri 2℃ndi zokwanira kuvulaza nkhuku kwambiri.
