Itsika yakajairika kushandisa mhepo inofefetera kuti itonhodze huku mumwaka wekupisa wezhizha. Kurimwa kwemazai kwakanyanya-density, kumhanya kwemhepo muchikwere chehukuinofanira kusvika inenge 3m / s, uye mhepo inomhanya muimba yehuku munzvimbo dzepamusoro-soro uye nzvimbo dzine hunyoro hunofanira kusvika kudarika 4m / s kuitira kuti uwane "mhepo inotonhorera" iri nani.
Izwi rekuti “wind-cooling effect” rinonyanya kureva kumhanya kwemhepo kuderedza kupisa kwehuku.
Kumhanya kwemhepo kungaite zvakadii patembiricha yehuku?
Maererano neongororo yakaitwa neUniversity of Georgia, mhepo yakawedzera kubva pa0m/s kuenda pa2.54m/s.°C.”
Kuti ndiwane kumhanya kukuru kwemhepo, ini ndiri tsika yakajairika kugadzira iyochicken housesirin'i, kuderedza kureba kwechikwere chehuku, kana kubva pamusoro pechikwere chehuku padenga rine mativi matatu zvakadzika zvichidzika daro rimwe nerimwe kuti uise chinovhara mhepo kana keteni rekuvharisa mhepo kuderedza nzvimbo yakachinjika yechikwere chehuku kuvandudza kukurumidza kwemhepo muchirugu.
Sei uchiita izvi, kunyanya nekuti kumhanya kwemhepo kunoenderana zvakanyanya nenzvimbo yemuchinjikwa-chikamu chechikwere chehuku.
Kuverengera kwekumhanya kwemhepo muhuku yakarebesa inofefetera: kumhanya kwemhepo = vhoriyamu yekufemesa / mhiri-chikamu nzvimbo yehuku.
Zviripachena kubva pane iyi fomula kuti kuwedzera kukurumidza kwemhepo kwekombi, kuwedzera kufefetedza kwepombi, kureva kuwedzera huwandu hwemafanhi anopikisa zvisina kunaka, kana kudzikisa nzvimbo yakachinjika yecoop.
Kuwedzera mafeni kunoreva kuwedzera mitengo, kuwedzera mashandisirwo emagetsi, kuwedzera mari yekugadzirisa, uye nekufamba kwenguva kuwedzera mari yekushandisa kune bhizinesi.
Wobva wawedzera kumhanya kwemhepo kunofanirwa kutariswa kubva pakudzikisa iyo mhiri-chikamu nzvimbo yechikwere chehuku. Pazasi tinonzwisisa shanduko yehuku isati yasvika uye mushure mekuwedzera keteni rekudzivirira mhepo nemaverengero chaiwo.
Semuenzaniso: chikwere chehuku 12m yakafara, 100m kureba, madziro epadivi echuru akareba 2.4m, pakati pechuru (yepamusoro-soro) 4.8m, iyo coop inoiswa ine 10 50 inch mafeni, mhepo yekufemesa yefeni imwe neimwe pa -50 Pa ndeye 31000m.³/h.
Ipapo kumhanya kwemhepo kwechikwere chehuku kunofanirwa kunge kuri: kumhanya kwemhepo = vhoriyamu yemhepo / nzvimbo yepakati-chikamu = 31000 / 3600× 10 / [12× (4.8 + 2.4) / 2] = 86.1/43.2 = 1.99m / s
Kana tikaisa sirin'i kana chidzitiro chemhepo muhoko yehuku, kuitira kuti kureba kwepamusoro pehuku kana kumucheto kwezasi kwe drape kubva pasi kune 3.6m, uye kureba kwemativi maviri ehuku kunoramba kusingachinji, mhepo inomhanya = 31000/3600.×10/[12×(3.6+2.4)/2]=86.1/36=2.39m/s
Naizvozvo, kana iri nhamba imwechete yevateveri, nekudzikisira nzvimbo yakachinjika yeimba yehuku inogona kuwedzera kumhanya kwemhepo pahwaro hwekutanga 0.4m/s, ndiko kuti, kugona kwakawedzera ne20%, shanduko yekumhanya kwemhepo inogadzirwa nemhepo yekutonhodza mhedzisiro inosiyanawo, mutsauko uripo pakati pemhepo mbiri yekutonhora inoenderana nekudziya kweanenge 2.℃, kana iri tembiricha yakanyanya, musiyano wetembiricha we2℃zvakakwana kukuvadza huku.
