Ndi chizoloŵezi chofala kugwiritsa ntchito mpweya wolowera m'mwamba poziziritsa nkhuku m'nyengo yotentha.Pakuti mkulu-kachulukidwe tima dzira ulimi, mphepo liwiro mukhola la nkhukuIyenera kufika pafupifupi 3m/s, ndipo liwiro la mphepo m'khola la nkhuku m'malo otentha kwambiri ndi chinyezi liyenera kupitirira 4m / s kuti "mphepo yoziziritsa" ikhale yabwino.
“Mphepo yoziziritsa” imatanthauza kuthamanga kwa mphepo pofuna kuchepetsa kutentha kwa thupi la nkhuku.
Kodi liwiro la mphepo lingakhudze 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 kupitirira 6°C.”
Kuti ndipeze liwiro lalikulu la mphepo, ndimakonda kupangankhuku nyumbaDenga, chepetsa utali wa khola la nkhuku, kapena kuchokera pamwamba pa khola la nkhuku padenga la makona atatu molunjika pansi pa mtunda wina uliwonse kuti akhazikitse zotchingira mphepo kapena nsalu yotchingira mphepo kuti muchepetse chigawo chapakati cha khola la nkhuku kuti mphepo isamayende bwino. mu coop.
N'chifukwa chiyani izi, makamaka chifukwa mphepo liwiro ndi zogwirizana kwambiri ndi dera mtanda wakhola la nkhuku.
Kuwerengera liwiro la mphepo mu khola la nkhuku lokhala ndi mpweya wautali: liwiro la mphepo = kuchuluka kwa mpweya / malo opingasa a khola
N'zoonekeratu pa chilinganizo ichi kuti kuonjezera mphepo liwiro la khola, mwina kuonjezera mpweya wa khola, mwachitsanzo kuonjezera chiwerengero cha zoipa mavuto kugonjetsedwa mafani, kapena kuchepetsa mtanda-Sectional dera khola.
Kuchulukitsa mafani kumatanthawuza kukweza mtengo, kugwiritsa ntchito magetsi, kuonjezera mtengo wokonza, ndipo m'kupita kwanthawi kumawonjezera ndalama zoyendetsera bizinesi.
Ndiye kuonjezera mphepo liwiro ayenera kuganiziridwa kuchokera kuchepetsa mtanda-gawo la dera lakhola la nkhuku.Pansipa timamvetsetsa kusintha kwa khola la nkhuku isanayambe komanso itatha kuwonjezera nsalu yotchinga mphepo ndi mawerengedwe enieni.
Mwachitsanzo: khola la nkhuku 12m m'lifupi, 100m kutalika, makoma am'mbali mwa khola ndi 2.4m kutalika, pakati pa khola (wapamwamba kwambiri) ndi 4.8m, kholalo limayikidwa ndi mafani 10 50 inchi, mphamvu ya mpweya wabwino. zimakupiza aliyense pa -50 Pa ndi 31000m³/h.
Ndiye liwiro la mphepo ya khola la nkhuku liyenera kukhala: liwiro la mphepo = voliyumu ya mpweya wabwino / malo odutsa = 31000/3600× 10/12× (4.8 + 2.4) / 2] = 86.1/43.2 = 1.99m / s
Ngati tiyika denga kapena chinsalu champhepo mu khola la nkhuku, kotero kuti kutalika kwa pamwamba pa khola kapena m'mphepete mwa denga la pansi ndi 3.6m, ndipo kutalika kwa mbali zonse za khola kumakhala kosasinthika, liwiro la mphepo ndi = 31000/3600×10/[12×(3.6+2.4)/2]=86.1/36=2.39m/s
Choncho, pankhani ya chiwerengero chofanana cha mafani, kuchepetsa malo amtundu wa nkhuku kungathe kuonjezera liwiro la mphepo pamaziko a 0.4m / s oyambirira, ndiko kuti, kuyendetsa bwino kumawonjezeka ndi 20%, Kusintha kwa liwiro la mphepo komwe kumapangidwa ndi kuziziritsa kwa mphepo kumakhala kosiyana, kusiyana pakati pa kuzizira kwa mphepo kumagwirizana ndi kutentha kwa pafupifupi 2.℃, pakakhala kutentha kwakukulu, kusiyana kwa kutentha kwa 2℃ndi zokwanira kuwononga kwambiri nkhuku.
