Izinhlelo Zokulahla: Kanjani Okuqukethwe Kwe-Pholycarbonate Nokwamaphaneli AseMetalwa Kuhlukile
Ukulahla Kanye Nezinhlelo Zomthwalo
Ukuthi ukushisa kuhamba kahle kangakanani ezintweni kuxhomeke ekuqondiseni kwazo ukushisa. Ngokwesibonelo, ukuthatha izinsimbi - insimbi iqhuba ukushisa cishe ngo-50 watts ngemitha ngayinye, kuyilapho i-aluminium iqhuba ukushisa ngokushesha kakhulu cishe ngo-237 W/mK ngoba lawo ma-electron akhululekile ahamba kuyo yonke indawo. Yingakho izinsimbi zingenazo izivimbeli ezinhle. Ngakolunye uhlangothi, i-polycarbonate eqinile ivumela kuphela ukushisa okungu-0.22 W/mK ngenxa yesakhiwo sayo samangqamuzana lapho amaketanga ehlanganiswe khona eduze, okuvimbela amandla ukuba angadluli kalula. Lokhu kuhluka okuyisisekelo ezingeni le-athomu yikona okwenza i-polycarbonate ibe i-insulator enhle kangaka ngisho nangaphandle kokumbozwa noma izingqimba ezengeziwe. Phakathi naleso sikhathi, uma othile efuna ukusebenzisa amashidi ensimbi ajwayelekile njengokuvikela, kuyodingeka enze izinguquko ezinkulu ukuze avimbele ukushisa konke ukuba kungaphumi.
I-Multi-Wall Polycarbonate: Ukusebenzisa Izikhala Zomoya Ukuze Uthuthukise Inani Le-R
Izikhawu ze-Polycarbonate neziningi zomgudu zisebenza kahle ekugcineni umthwalo ngoba zinezikhala ezithunyelweyo zomoya phakathi kwazo. Umoya akaphila kakhulu umthwalo (ngokungange 0.026 W/mK ukuba siyagcina teknikalis), ngakho ke lezi ziphetho zomoya zibe neminikelo ethembekileyo ekukhawukeni umthwalo. Kutheni lokhu kusho? Izi-R-value ezaphezulu, okwenzela ukuthi kubonakale konke okukhawuka ngokuthintela umthwalo. Izinhlobo ezinezintathu zingafinyelela ngeka-R-3.5 ngoluchaba, okwenzela ukuthi zibeke ngaphezulu kwamandla amaningi okwakhiwa ngokuvuselela izimo. Abakwaqondisi bafisela lezi ziphetho ezindaweni zomnyango nezindawo zangaphandle yezindlu ngoba zabelana nomgcobo wokugcina umthwalo ngaphandle kokunyangeza ubunzima bezakhiwo. Ubuncane bezikhawu ngokuvuthiwe nesimo sezobuchwepheshe kuyazenza ikhetha elihle yezindlu zomnotho ezingathwala amathuba okunciphisa izindleko zokusebenza kwezimali ngaphandle kokuthuthukisa izimo zangaphakathi.
Izikhawu ZeNhlangothi: Kusuka KuMahluko Wezinhlelo KuMahluko WeNhlangothi Ogcineni Umthwalo (IMPs)
Izihlalo ezizinzile zingazange zilungiselela kakhulu futhi zidinga ukuthi umthwalo usuke ngazo kakhulu. Lapho-ke izihlalo ezilungiseleyo zazama. Lezi zihlalo zinezikhumba esimbiwe sokuphuma kwamathuba, okwenzekayo ngokuvamile ngezinto ezjikeleza i-polyurethane noma i-polyisocyanurate, ezigcineniwa phakathi kwezimbombo ezimbili. Okwenzela ukuthi le zihlalo zenzeke kahle kukhona ukuthi izindlela zezifomu zibophephe kahle, okusondela kakhulu, okwenzela ukuthi umthwalo ungasebenzi kakhulu ngaphakathi kwehlalo. Kukhona okukodwa okuthola amalungiso angama-R-8 ngalolunye ulungu olubanzi. Ngempela, i-IMPs ingcono kakhulu ekuvikeleni izinselelo, ingahlali kudla, futhi ibulalele amaduza kahle. Kodwa kukhona indaba: zizinzile kabonakalani, azikwazi ukubuka kakhulu, futhi zidependa kabangcolweni kuleli gumbi elumaphakathi lokulungisa. Ngokulinganisa lokhu nokuthi njengezihlalo ze-polycarbonate ezibukeka kahle ezivumela umnyango wokulunga kodwa zilungisa kahle. Ngenkathi i-IMPs, uma umuntu ufuna izinconywa ezifana nezihlalo ezibukeka kahle, kudinga ukuthuthwa okuningi kumaqondo noma izihlalo eziningi ukuze abe nenhlanhla yokuqukatha nokulungisa.
Ukusebenza Okususelwa Kwezulu: Ipolikhabhonethi vs. Imetali Kuzindlela Ezithile
Uhkathi Lwesabatha: Ukuthutha Kwesimanga, Ukuqina Kwe-UV, Nokudala Kwesikhala Somjane Ngepolikhabhonethi
Ipolikhabhonethayile ikhona ngokugqithile kulezikhathi ezikhulu ngoba iyaphakathi izimo ezihlisa ngokuhle nophazamo oluhle lwamandla. Umfanekiso wamandla wamandla wahlukana ngokuphazamise kwezindlela zokuhlisa kwenzeka ngama-30% ngokulinganisa nendlela ephathelene ngaphandle kwezinsimbi. Ngaphezulu, iico eziqinileyo ze-UV zikhubaza kakhulu kuma-99% wamandla ezingenelo ezingavimba, okusho ukuthi umlango akayiphazamisa kakhulu noma kungcono kakhulu. Izigaba zephepha zinjalo into enkulu. Uma kuselwa kusobuso, iinsimbi ezinzima zingaphazamisa kakhulu, kungakhathalela kakhulu kumazibhalo amakhulu kumazibhalo amakhulu (oko kungu-66 Celsius). Kodwa ipolikhabhonethayile ikhona ngokunciphisa, ngokuvamile ikhona ngaphansi kwe-120 F (ngaphakathi kwe-49 C). Lokhu kuthatha uhlelo olukhulu kumakhaya afunayo ukunciphisa ukusebenza kwezixhobo zokulahlela nokuhlisa, kwaye abantu bakhona ngokuhle kakhulu. Sibonisa lo msebenzi ngokugqithile kumakhaya apho izinto ezintsonkothile zingaphazamisa kakhulu, iibhaski zezindlela zokugcina, kwaye kumazibhalo amakhulu apho ukulungisa kakhulu kwezigaba kumakhaya akhona ngokugqithile kumahluko wokuphila.
Ubudlozi: Uhlaziyiyo Lwokukhanya, Ukudluliswa Kwesibindi, nokweba Kwezindlela Zokugcina Umthubi
Imvula engaqondene iyaphatha iingcinga ezinzima kakhulu ngoba zihlawula umthubi kakuhle, yenza le nkqubo eziphazanyayo apho iifastener zixhaphakisha, phantsi kwemigca, kwiindawo zokudibanisa. Kutheni oku kubakho? Le ndawo enqelene kumgangatho ikhupha umgangatho wamandla ngezantsi kumgangatho othiwa yi-dew point, oko kuthetha ukuthi kukhona ukungcola kwamandla futhi ekugcineni kukhona ukulahlwa kwamandla. Manje i-polycarbonate ichasa ngendlela eyodwa. Ngenkqubo yokungahlanjiswa engaphezu kuka-0.22 W/mK kunye nezikhumba zokugcina amandla ephinde zenze izikhumba, igcina ubomi bokunyuka kumgangatho obumbila xa kuyophula ku-minus 40 degrees Fahrenheit noma Celsius. Kunye nale ncwadi ephezulu eyenzelwe ukungabambeki komtshane, ngoko ke amakhaya agcinela kahle ngexesha lenyaka ngaphandle kokudinga iivapori ezinye noma iinkcukacha ezide zokwenza into ayikwaziyo ukwenza ngokwayo ngokuba imvelaphi ayisebenzi.
Ubushushu Bekhono Nokuhlanganiswa Kwe-Envelope Yebhinga
Izimpondo Ze-Daylighting Ne-Gcobo Lokubala Kwemali Ethelele Kwesikhwama SePolycarbonate Esibonakalayo
Izipaneli ze-polycarbonate zinikeza okuthile okhaziyekile kubunzima obudinga ukulahlwa okubi kanye nokugcina kahle. Le zimbini izinto njalo zingavumelana kakubi ekubunjini, kodwa polycarbonate ye-translucent inkathi yenzela lokhu. Lomkhepha uthola kusengaphakathi 80-90% wezilwanyana zokubonakala, okusho ukuthi izindawo kusengaphakathi zithola ukulahlwa kwakhe kusuku. Izintonga zibonisa ukuthi lokhu kungakhipha ukusetshenziswa kwezinhloso ngibeleyi ngenkathi yesithathu uma kulinganiswa nezindlu zezinhloso ezingavimba konke okulahlwa. Kukhona okuthandekile ngendlela lomkhempa kushaya okulahlwa okungahlali kwenza amasonto okomnyama noma ukulahlwa okungakwenzekile, ngakho-ke kugcina ukungena kwesimnyama esingaphezulu. Ngeminyaka engaqondile, amapokhi wamandla phakathi kwezimvamvu zisetyenziswa njengabasebenzi, ukunciphisa ukusetshenziswa kwesitimela ngaphandle kokuthuthukisa kakhulu isitimela. Uma kudwelene nalesi ziphaneli nesistimu esihle sezokulungisa izimo zomhlaba, kanti kwenza into eyodwa yokungcono kwezimali. Ngokwesicwangcwa sase-US Department of Energy, izindlu ezifaka izindlela ezihle zokudluliswa okulahlwa kanye nezinto ezinamandla okudluliswa okuphansi kanye nokugcina okubi kungakhipha ukusetshenziswa kwezimali kusengaphakathi kwe-20-30%.
Isikhombisi Sokuqala
Uyini ukulahlwa kwezindawo zezulu?
Izindawo zezulu, njengasezinzini kanye nasekayalini, zinezindawo ezikhethekileyo zokulahlwa, okusho ukuthi zilahlwa kahle. Isikayalini silahlwa ngokushesha ngama-50 watts ngumitha kelvin, ngelokhu isilumini silahlwa ngokushesha ngama-237 W/mK.
Kungani izizinda zezindawo zomgquba wezindawo zezindawo zomgquba?
Izindawo zomgquba eziningi izindawo zinezindawo ezithunywa zezulu ezinikela ukulahlela okuhle kanye nezimali ezide. Zilula kakhulu kanye zinikela ukulahlela okuhle ngaphandle kokunakekela kakhulu, futhi zibe yisiko esihle kumakhambi.
Izizinda zezindawo zezulu zisebenza kanjani?
Izizinda zezindawo zezulu ziqukethe izici ezinamandla efothi ezithunywa phakathi komaqondo amabili ezulu, zinikela izici ezihle zokulahlela. Zinikela izici zokulahlela ngama-R-8 ngincinci kude kanye zisebenza ngokuhle kungako amandla, umlilo, kanye nesililo esingena.
Izindawo zomgquba zisebenza kanjani emakhaya aphelile?
Izipaneli ze-Polycarbonate zilungisa ukuthuthukisa kwesibhedlela ngama-30% kuphela kunemipaneli yemikhumbi engcono futhi zinezimbondo ze-UV ezivikela ukulahlekelwa kwemithi. Zilahle umphumulo okwesibhedlela kumzila wemikhumbi, ukunciphisa izidingo zokulahla.
