Kuwumkhuba ovamile ukusebenzisa umoya ovunguzayo oqondile ukuze kuphole izinkukhu ngesikhathi sasehlobo esishisayo. Ukuze kufuywe amaqanda amaningi kakhulu, isivinini somoya sincishiswa kakhulu.ihhoko lezinkukhukufanele ifinyelele okungenani ama-3m/s, futhi isivinini somoya endlini yezinkukhu ezindaweni ezinokushisa okuphezulu kanye nomswakama ophezulu kufanele sifinyelele ngaphezu kwama-4m/s ukuze kutholakale "umphumela wokupholisa umoya" ongcono.
“Umphumela wokupholisa umoya” ubhekisela kakhulu esivinini somoya sokunciphisa izinga lokushisa lomzimba wezinkukhu.
Isivinini somoya singaba nomthelela ongakanani ekushiseni komzimba wezinkukhu?
"Ngokocwaningo olwenziwe yi-University of Georgia, isivinini somoya sikhuphuke sisuka ku-0m/s saya ku-2.54m/s. Izinga lokushisa lomzimba lezinkukhu lizokwehla ngama-degree angaphezu kuka-6."°C.
Ukuze ngithole isivinini esikhulu somoya, ngingumkhuba ojwayelekile ukwenzaindlu yenkukhuuphahla, nciphisa ukuphakama kwehhoko lezinkukhu, noma kusukela phezulu kwehhoko lezinkukhu ugobe uphahla oluyinxantathu uqonde phansi njalo ngebanga elithile ukuze ufake ikhethini lokuvimba umoya noma ikhethini lokuvimbela umoya ukuze unciphise indawo enqamula ihhoko lezinkukhu ukuze uthuthukise isivinini somoya ehhoko.
Kungani lokhu kwenzeka, ikakhulukazi ngoba isivinini somoya sihlobene eduze nendawo enqamulayo ye-ihhoko lezinkukhu.
Ukubalwa kwesivinini somoya ehhokweni lezinkukhu elinomoya ovulekile isikhathi eside: isivinini somoya = ivolumu yomoya / indawo enqamula ihhokweni
Kusobala kule fomula ukuthi ukwandisa isivinini somoya sendlu, kungaba ukwandisa umoya wendlu, okungukuthi ukwandisa inani labalandeli abamelana nokucindezela okungekuhle, noma ukunciphisa indawo enqamula indlu.
Ukwandisa amafeni kusho ukwandisa izindleko, ukwandisa ukusetshenziswa kukagesi, ukwandisa izindleko zokulungisa, futhi ekugcineni ukwengeza izindleko zokusebenza ezibalulekile ebhizinisini.
Khona-ke ukwandisa isivinini somoya kufanele kucatshangelwe kusukela ekunciphiseni indawo enqamulayo yeihhoko lezinkukhuNgezansi siyaqonda izinguquko zehhoko lezinkukhu ngaphambi nangemva kokukhulisa ikhethini elivimba umoya ngokubala okuqondile.
Isibonelo: ihhoko lezinkukhu elingamamitha ayi-12 ububanzi, ubude obungamamitha ayi-100, izindonga eziseceleni zehhoko zingamamitha ayi-2.4 ukuphakama, maphakathi nehhoko (eliphakeme kakhulu) lingamamitha ayi-4.8, ihhoko lifakwe ngamafeni ayi-10 angu-50 intshi, amandla okungenisa umoya wefeni ngayinye ku--50 Pa angamamitha ayi-31000³/h.
Khona-ke isivinini somoya sehhoko lezinkukhu kufanele sibe: isivinini somoya = ivolumu yomoya / indawo enqamulayo = 31000 / 3600× 10 / [12]× (4.8 + 2.4) / 2] = 86.1/43.2 = 1.99m/s
Uma sifaka ikhethini lophahla noma lomoya ehhokweni lezinkukhu, ukuze ukuphakama kwengxenye ephezulu yehhokweni noma umphetho ongezansi wendwangu kusukela phansi kube ngu-3.6m, futhi ukuphakama kwezinhlangothi zombili zehhokweni kungashintshi, isivinini somoya singu- = 31000/3600×10/[12]×(3.6+2.4)/2]=86.1/36=2.39m/s
Ngakho-ke, uma kunenani elifanayo labalandeli, ngokunciphisa indawo enqamulayo yendlu yezinkukhu kungandisa isivinini somoya ngesisekelo se-0.4m/s yokuqala, okungukuthi, ukusebenza kahle kukhuphuke ngo-20%, izinguquko zesivinini somoya ezikhiqizwa umphumela wokupholisa umoya nazo zihlukile, umehluko phakathi komphumela wokupholisa umoya ohambisana nokushisa okungaba ngu-2.℃, uma izinga lokushisa liphezulu kakhulu, umehluko wokushisa u-2℃kwanele ukubangela umonakalo omkhulu ezinkukhu.
