Ngaba ukhathazekile malunga nokhuseleko lwezibane ezinde ezikwindawo yakho yangaphandle? Udinga umlinganiselo oqhelekileyo ukuqinisekisa ukuba ezo zibane ziphezulu ziyakwazi ukumelana neemeko zomoya. Kulapho ufuna khona amanqaku e-EPA.
Ngokusisiseko, ireyithingi ye-EPA luhlobo lohlalutyo olwenziwayo ukuqinisekisa ukuba izibane zangaphandle kwiindawo eziphakamileyo ziya kuhlala zizinzile xa umoya uvuthuza. Umzekelo, izixhobo zokukhanyisa kufuneka zihlangabezane neemfuno zeendawo ezifana nonxweme, ichibi, kunye nemimandla yeentaba. Ngenxa yesi sizathu, kubalulekile ukuqwalasela amanqaku e-EPA ngelixa ufaka izibane zeepali.
Namhlanje, ndiza kuchaza ngakumbi ngesi sihloko sobugcisa ukuze usiqonde ngcono.
Yintoni i-EPA?
Uhlobo olupheleleyo lwe-EPA yi-Effective Projected Area. Eli gama lilinganisa izinto ezinemilinganiselo emithathu kwindawo enemilinganiselo emibini. Kwakhona, libhekisa kwindawo ebonakalayo yesimo esinemilinganiselo emithathu ngokuchasene nomoya kwi-engile ethile.
Umzekelo, imilo yekhowuni enamacala amathathu iyahluka ngokusekelwe kwii-engile ezahlukeneyo. Ngamanye amaxesha ifana nonxantathu, kwaye ngamanye amaxesha ifana nesangqa. Enyanisweni, zonke izinto zokukhanyisa, ezifana nepali, i-fixture, kunye ne-teno, ziya kuba neereyithingi ze-EPA ezahlukeneyo. Ngoko ke, kuya kufuneka ubale i-EPA iyonke ngelixa useta inkqubo yokukhanyisa.
Ithini i-EPA Wind Rating?
Uvavanyo lomoya lwe-EPA lixabiso elilinganisiweyo lesantya somoya esiphezulu esinokumelana naso ngokukhuselekileyo isixhobo esifakwe kwipali. Ukucacisa, ibala indawo iyonke yomphezulu wesixhobo esinokuxhaswa yipali kwisantya somoya esithile. Ngale xabiso, uya kufumana umbono wobume besakhiwo seepali zakho kunye nezixhobo xa zithelekiswa neemeko zomoya ezimbi kakhulu. Kwimeko yezibane ezikhukulayo, i-EPA ilinganisa amandla epali yokukhanya.
Umzekelo, iindawo ezinomoya onamandla ezifana neMiami kunye neHouston eMelika zijongene nomoya ovuthuzayo we-110 MPH (iimayile ngeyure). Ngoko ke, kuya kufuneka ukhethe ipali yokukhanya enomlinganiselo we-EPA onokumelana neemeko zomoya ze-110 MPH.
Umoya Uzichaphazela Njani Iipali Zakho Zokukhanya?
Umoya ubangela ukungcangcazela kwemo yokuqala okanye kwemo yesibini emva kokubetha ipali yokukhanya. Umoya ovuthuzayo nowesantya esiphezulu ubangela ukungcangcazela kwemo yokuqala xa ushukumisa incopho yepali. Nangona kunjalo, olu hlobo lokungcangcazela ludla ngokuba yingozi, njengoko iipali zokukhanya ziguquguquka ngokwaneleyo ukuba zikwazi ukusingatha intshukumo. Ngokwahlukileyo koko, ukungcangcazela kwemo yesibini okanye i-Aeolian kuyingozi. Apha, umoya ozinzileyo nowesantya esiphantsi, ohamba rhoqo uchaphazela umbindi wepali. Ngenxa yoko, imiba eyahlukeneyo efana nezibane eziqhekekileyo, ukwaphuka koxinzelelo, ukugqwala, kunye nokungaphumeleli kwepali kunokwenzeka kule meko. Kuya kufuneka usebenzise i-vibration dampener ukunciphisa esi siphumo.
Ukubaluleka Kovavanyo lwe-EPA
Ukuthintela Iziganeko Eziyingozi
Izixhobo ezifakwe kwimiqolo kufuneka zikwazi ukumelana namandla omoya kwindawo ethile. Ukuqwalasela umlinganiselo ochanekileyo we-EPA kuqinisekisa ukuba iimpondo azigobi okanye aziwi phantsi kweemeko zomoya ezimbi kakhulu.
Ukuqonda Iimfuneko Zesantya Somoya
Uya kufuna ulwazi oluchanekileyo malunga neemeko zomoya kwiindawo ezahlukeneyo ngaphambi kokuba ulungise iipali zokukhanya. Uvavanyo lwe-EPA lukunceda uqonde iimfuno zesantya somoya.
Ukulungisa Iimfuno Zokufaka
Iireyithingi ze-EPA zeepali kunye nezixhobo zokukhanyisa ziyafuneka ukuze uqonde ukuba loluphi uhlobo lwezixhobo ozidingayo xa ufaka inkqubo yokukhanyisa.
Ungayilinganisa njani i-EPA Rating?
1. Ukubala i-EPA yeSixhobo esinye
Ifomula ye-Effective Projected Area okanye i-EPA yile ilandelayo:
| Indawo Eqikelelweyo Esebenzayo (i-EPA) = Indawo Eqikelelweyo (A) x I-Drag Coefficient (Cd) x I-Gust Factor |
- Umlinganiselo we-A: Indawo yeProjekthi (PA) ibhekisa kwindawo ephezulu enqamlezileyo yesibane kunye nokufakelwa kwaso xa sifakwe. Iyunithi yale gama ziimitha ezisikwere.
- Ukulinganiswa kweCd: I-Drag Factor (i-Cd) ithetha ukuba into okanye imo inokubonisa ukumelana okungakanani emoyeni. Yinto engalinganiyo engenamlinganiselo echaphazeleka bubuninzi bomoya, isantya, kunye nendawo yangaphambili. Uxinano lomoya kufuneka luhambelane neemeko zomgangatho wolwandle kwi-15°C. Ukongeza, i-drag coefficient ephezulu ithetha ukuba into inokumelana nomoya ngakumbi. Ngokwahlukileyo koko, izinto ezine-drag coefficient ephantsi azimelani nomoya kakhulu.
- Ingxaki Yesivuthuvuthu: Le nto ibhekisa kuxinzelelo lomoya oluphezulu ngenxa yeemeko ezivuthuzayo. Linani elingenamlinganiselo elinikwe kwiikhowudi okanye imigangatho yokwakha.
Umzekelo wokubala: Masithi isibane sinendawo eqikelelweyo ngaphambili eyi-0.158 square feet, i-drag coefficient eyi-1.20, kunye ne-gust factor eyi-1. Emva koko, i-EPA yayo iya kuba yi-0.158* 1.20 * 1 = 0.190 square feet.
2. Ukubala i-Total EPA kwi-Light Pole Assembly
Apha, udinga i-EPA yazo zonke izinto zendibano ye-light pole. Ngoko ke, sebenzisa le fomyula ilandelayo ukubala i-EPA iyonke ye-light pole yakho:
| (I-EPA yezibane X ubungakanani bezibane) + (I-EPA yezibane X ubungakanani bezibane) + (I-EPA yezibane X ubungakanani bezibane) + (I-EPA yezibane X ubungakanani bezibane) |
Masithi ii-EPA zezixhobo zokukhanyisa ezimbini ziyi-5.2 square feet. I-bracket enye ine-EPA eyi-2.1 square feet, kwaye enye ine-EPA eyi-0.8 square feet.
Isimbuku se-EPA siya kuba yi-(5.2 * 2) + (2.1 * 1) + (0.8 * 1) = 13.3 square feet.
Ungayithenga njani i-Light Pole usebenzisa itshati ye-EPA?
- Ekuqaleni, fumana indawo yomoya apho uza kufakela khona izibane ezivela kwimephu yesantya somoya yelizwe lakho.
- Emva koko, linganisa i-EPA iyonke yazo zonke izinto ezifakwe kwipali. Uza kufumana amaxabiso e-EPA kumaphepha eenkcukacha zeemveliso.
- Ngoku khangela i-EPA ephezulu yendawo yakho yomoya kwitshathi.
- Qinisekisa ukuba i-EPA iyonke yezixhobo zakho ingaphakathi kwe-EPA ephezulu evumelekileyo kuloo pole. Ngaphandle koko, kuya kufuneka uthenge ipali engcono yeprojekthi.
Ungaziqonda njani iimfuno ze-EPA zeProjekthi yakho?
- Okokuqala, gqiba ngendawo oza kuyimisela kuyo inkqubo yokukhanyisa.
- Emva koko bala i-EPA kunye nobunzima bendibano yepole iyonke.
- Emva koko, yenza uhlalutyo lomthwalo womoya ukuze kuqinisekiswe ukuba umthwalo womoya uyimfuneko.
- Okokugqibela, thatha iingcebiso ezivela kubavelisi beepali ukuqinisekisa ukubala kunye neemeko zasekuhlaleni.
Izinto Ezichaphazela Iimfuno ze-EPA zeSibonda Esikhanyayo
- Uhlobo kunye neNani leeLuminaires: Izixhobo zokukhanyisa ezahlukeneyo zine-EPA ezahlukeneyo ngokusekelwe kuyilo, ubungakanani, kunye nokuma. Kwakhona, inani eliphezulu lezibane ezikwipali likhokelela kwindawo engaphezulu eya kuvezwa ngumoya. Ngoko ke, iimfuno ze-EPA ziyatshintsha ngohlobo kunye nenani lezibane.
- Ubunzima beZibane zokukhanya: Izixhobo zokukhanya ezineentsimbi ezinzima zinamandla ngakumbi kwiipali zazo, nto leyo echaphazela umoya wepali.
- Izibiyeli Zokuxhoma kunye Nezixhobo: Izibiyeli zokuncamathisela isibane kwipali nakwezinye izixhobo zongeza indawo iyonke yomphezulu, i-drag coefficient, kwaye, ngenxa yoko, iimfuno ze-EPA zepali.
- Ubude bePole: Ukuphakama kwepali kutshintsha indlela ebalwe ngayo imfuneko ye-EPA. Umzekelo, iipali ezinde ziya kufuna izinto eziqinileyo njengoko zinomoya omninzi.
- Imilo yePole kunye neCandelo eliMnqamlezo: Iimilo ezahlukeneyo zepali zimele amanqaku ahlukeneyo e-EPA. Ngokubanzi, iipali zesikwere ziya kuba namanqaku aphezulu e-EPA kuneepali ezijikelezileyo. Ngaphandle koko, ububanzi kunye nobukhulu bodonga lwecandelo elinqamlezileyo lepali kuchaphazela amandla ayo okuthwala umthwalo.
- Uyilo lwezinto kunye nolwakhiwo: Izinto ezisetyenziselwa ukwenza ipali, njengentsimbi okanye i-aluminium, kunye noyilo lwesakhiwo zimisela amandla epali okumelana nemithwalo yomoya.
- Iimeko zomoya zasekuhlaleni: Kuya kufuneka ulandelele isantya esiphezulu somoya kwindawo yasekuhlaleni ngaphambi kokuba ubale amaxabiso e-EPA kwipali yokukhanya. Enyanisweni, iindawo ezinembali yesantya esiphezulu somoya ziya kuba neemfuno eziphantsi ze-EPA. Ke ngoko, kuya kufuneka ukhethe izixhobo ezincinci, izibiyeli, kunye nezixhobo zepali yokukhanya kwindawo enomoya omkhulu.
- Indawo yokufaka: Umhlaba ojikelezileyo, ukuchatshazelwa kwawo ngumoya, kunye nesantya sokungcangcazela esinokubakho kwindawo yokufakelwa kuchaphazela iimfuno ze-EPA zepali yokukhanya.
Ubudlelwane Phakathi kwe-EPA kunye ne-AASHTO Guidelines
The American Association of State Highway kunye namagosa ezoThutho (AASHTO) imisela izikhokelo ze-AASHTO, ezimisela indlela esetyenziswa ngayo i-EPA ekuyileni izakhiwo zokukhanyisa zangaphandle. Izikhokelo ze-AASHTO zinceda ekubaleni imithwalo yomoya kwizakhiwo, ezisetyenziswa ngokuthe ngqo ekubaleni i-EPA. Ngale ndlela, le migangatho inceda ekuqondeni iimfuno zesakhiwo seepali zokukhanya ukuze zimelane nomoya. Ukongeza, ziqinisekisa ukubalwa kwe-EPA kwiimeko ezisebenzayo.
