Ungakhetha kanjani ingilazi engcono kakhulu yokubaza futhi wonge imali?

Kuze kube manje, awukho umbhalo ofana nalo okhuluma ngendlela elula nefingqiwe mayelana nokuthi yiziphi izibuko ongakhetha kuzo zokubaza. Uzothola impendulo nencazelo ethize, ebhalwe ngendlela yokuthi wonke umuntu akwazi ukuyiqonda. Umbhalo ungakongela imali eningi, kodwa futhi uqede izinkolelo ezikhona phakathi kwabantu 95%.

Glass ithatha indawo enkulu yewindi (evulayo). Njengoba kubalulekile ukuthi amaphrofayili enziwe ngokhuni ahlanganiswe ndawonye, kubaluleke kakhulu ukuthi ingilazi ingakukhiphi ukushisa egumbini ebusika, nokubanda ehlobo.

Isithombe 1 – Ug kanye no-g factor

Ngakho-ke kunezici ezimbili ezichaza lawa manani:

Ug factor imele ukulahlekelwa ukushisa (amandla) okuvela egumbini. Uma kunegumbi elishisisa ebusika, lesi sici sizobonisa ukuthi kungakanani ukushisa okudlula engilazini bese kuphumela ngaphandle.

           Uchwepheshe: Ug - i-coefficient yokudlulisa ukushisa, evezwa ngokwezinga le-EN-673, iyunithi yayo engu-W/m2K. Ukuncipha kwevelu ye-U, kuba ngcono ikhono lokufaka i-thermal.

G factor indlela yokushisa eya egumbini. Ngokuphambene nendlela yokuqala, uma sinegumbi elinesiphephetha-moya ehlobo, le nto isho ukuthi kungakanani ukushisa okudlula engilazini.

            Ochwepheshe: g - ukudlula okuphelele kwamandla elanga engilazini. Ivezwa ngokuya nge-EN-410 ejwayelekile. Uma iphansi, kuyancipha ukushisisa kwendawo yangaphakathi.

Asihambe ngohlelo.

Ingilazi yongqimba olulodwa.

Eg. ehlobo, uma amazinga okushisa esuka ku-35o ukuya ku-40o, ingilazi efudumele idlulisela ukushisa kwayo ekamelweni. Uma leyo ngilazi ingeyodwa (yithi 3mm ugqinsi), izosebenzisa 100% kusukela ekutheni ishisa kangakanani. Lapha, kufanele sikugcizelele ngokushesha lokhu “kusukela ekufudumaleni okungakanani” futhi sithi uma ingaphandle isib. 40 degrees, ngeke ngempela ibe amadigri angu-40 ngaphakathi, kodwa izoba ngendlela efanayo nengilazi ngokwayo ekwazi ngayo ukushisa (isithombe 2), ngoba ikhipha lokho kushisa empeleni (okuthi esimweni sengilazi eyodwa kuzoba 100% ekushiseni). Kufana nokuba ne-heater yengilazi ekamelweni. Lesi yisimo sokushisa esidlula ngaphandle siye ngaphakathi (G factor).

Figure 2 - Izinga lokushisa lengilazi liku-0ngaphandle kanye 20o ngaphakathi kwamazinga okushisa

Uma kukhulunywa ngokudlula kwamandla ukusuka ngaphakathi ukuya ngaphandle (I-Ug factor), endabeni yengilazi eyodwa cishe kucishe kube 83% wamandla. Okusho ukuthi, 83% emakhazeni (ehlobo) ilahleka ngaphandle.

Manje sesiza ekutheni i-coefficient ye-Ug iyini ngempela. Ngalolu hlobo lwengilazi, abantu babe sebethi i-Ug yayo ithi 5,3 kuya kokuthi 5,8. Lawa ama-coefficients aboniswa njengama-coefficients conductivity engilazi.

Sinalolu hlobo lwengilazi ezindlini ezindala. Njengoba lokhu kulahlekelwa kwamandla kuphezulu kakhulu, amawindi acwebezeliswe kabili enziwe (amaphiko amabili ahlukene, elinye ngemuva kwelinye) futhi sisenamafasitela anjalo namuhla kwezinye izindlu nezakhiwo (isithombe 3). Kwabe sekwenziwa isinyathelo esilandelayo sokuthuthukisa, okuyi…

Isithombe 3 - izinguqulo ezindala zamawindi alengiswa kabili

Ingilazi ekabili (kabili)

Ingilazi eyenziwe ngezingilazi ezimbili, futhi phakathi kwazo kukhona ukubumba isb.16mm (4+16+4).

Isithombe 4 - Izendlalelo ezimbili zengilazi ezinogqinsi 4mm, oluhlukanisa ukubumba kokuthi 16mm

Amanani okuqala nawokugcina “4” abonisa ukujiya kwengilazi okungu-4mm, futhi inani eliphakathi “16” libonisa ukujiya kokubumba okuphakathi kwawo. Ubukhulu bokubumba bungahluka ukusuka kokuthi 6mm kuye ku-24mm, kodwa ibanga elinikeza imiphumela ehamba phambili nalapho imiphumela iyinhle kakhulu yibanga (lokubumba) ukusuka kokuthi 12-16mm. Njengoba nje ukubumba okuvela kokuthi 6,8,9, mm akukuhle, ngakho-ke lezi ezisuka kokuthi 22, 24mm azilungile nazo (thina enkampanini singathi “ziphuka ngokufana”).
Manje njengoba sesazi ukuthi ilebula ngayinye isho ukuthini, yisikhathi esifanele sokunikeza ithebula esingalilandela.

Siyabona ukuthi ngemva kokwengeza ungqimba olulodwa lwengilazi esikhundleni senani le-Ug elithi 5.3, sithole ukuthuthukela kokuthi 2.8. Okungukuthi, esikhundleni sokuthi ukushisa okungu-100% kuphume ebusika, uthola ukuthuthukiswa kokuthi 56%, kanye nokushisa okungu-77% kungena ehlobo. Ngakho-ke sithole ukuthuthuka okukhulu ngokwengeza ingilazi eyodwa.

Isiphetho esinengqondo siyavela ngokushesha, “Bese wengeza olunye ungqimba lwengilazi (ingilazi enezendlalelo ezintathu) futhi sizothola imiphumela engcono kakhulu!”, kodwa akunjalo.

Kunamanani athile alungile afaka izici zokushisa/ezibandayo, ukukhanya kwelanga, njll. futhi sizobona ukuthi kusukela kuleli phuzu, ukwengeza esinye isendlalelo sengilazi esendlaleloni esivele sikhona kakade kungaba umnyakazo wokumaketha, umthengi okumele awukhokhe kahle.

Ngaphezu kwesinye isendlalelo engilazini enezingqimba ezimbili, kulo mzuzu, i-argon iphinde ifakwe endabeni, ekhuthazwa kakhulu ngabantu ababhekene nokumaketha ezinkampanini. Sisho okuningi, yiqiniso kunezizathu zokudumisa, kodwa ngokuqinisekile hhayi njengoba kushiwo futhi izizathu ezishiwo azilona iqiniso ngokuphelele. Kuthebula singabona ukuthi uma i-argon ifakwa engilazini evamile enezendlalelo ezimbili enenani le-Ug elingu-2.8, kutholwa inani le-Ug elithi 2.6. Lokho kuthuthukiswa okuncane okungu-0.2 kuphela kukhokhelwa kakhulu kunokuthuthukiswa kwangempela okuzuziwe. Lokhu kuthuthukiswa kuhle kuphela kwezinye izimo, futhi sizochaza ukuthi yikuphi kamuva.

Impela, sibhala konke lokhu futhi sikuhlobanise nengilazi enezingqimba ezimbili, ngoba “kunokuhlukahluka okuningi kwetimu”. Ake sithathe isibonelo sokuza kwakho esitolo sengilazi:

     Wena: Sawubona

     I-Glazer: Sawubona

     Wena: Ngifuna ingilazi eyodwa ye-iso, umoya omncane futhi ogcwele i-argon

     I-Glazer: Can

Umenzi wengilazi akazange aqambe amanga kuwe. Uthole ingilazi ye-iso ephumayo ephansi (LOW-E), egcwele i-argon, kodwa akazange akutshele ukuthi bekuyifilimu eqinile. Kuleyo ngilazi sithola i-Ug-1.8 futhi uma igcwele i-argon 1.6. Futhi ingabe uyabona kuthebula ukuthi ayini amanani engilazi ekhishwa kancane enefilimu ethambile (4+16+4 LOW-E SOFT FILM). Lelo nani, ngisho nangaphandle kwe-argon lingu-Ug-1.3, elingcono kunefilimu eqinile ene-argon, futhi intengo incane. Uma leyo glass iphinde igcwaliswe nge-argon, sithola i-Ug-1.1. Futhi lapha sifika esimweni lapho i-argon isho okuningi. Leli nani le-Ug-1.1 inani elidingekayo emithethweni eminingi yaseNtshonalanga Yurophu ekhuluma ngokulawulwa kwale ndawo, lapho ingilazi ilethwa ngaphakathi kwemikhawulo yamanani avunyelwe futhi ngenxa yalokho ingasetshenziswa embonini yezokwakha. Ngakho-ke i-argon ayikhokhiswa kakhulu ngenxa yokufakwa ngaphakathi, njengoba abantu abaningi becabanga, kodwa ngoba i-argon empeleni iyigesi engathathi hlangothi - ayibi njengomoya. Ifilimu ebekwe ngaphakathi kwengilazi (phakathi kwezingqimba ezimbili) isekelwe ku-aluminium oxide, futhi uma leso sikhala singagcwaliswa nge-argon, simane sigugulwe ngokuhamba kwesikhathi emoyeni ojwayelekile bese siyanyamalala, ngaleyo ndlela silahlekelwe ukufakwa kanye namanani ayo esasinawo ekuqaleni.

Futhi, kukhona abameli abathi, njengengxabano yokungangezi i-argon, bacaphuna iqiniso lokuthi i-argon “ivuza” engilazini ngokuhamba kwesikhathi, okungukuthi iyanyamalala futhi sikhokhela ukugcwalisa i-argon mahhala. Lokhu kuyiqiniso, kodwa kancane. Inani lokulahlekelwa kwe-argon lincike kumkhiqizi wengilazi, ngakho-ke ngokubambisana kufanele ukhethe izinkampani ezinesitifiketi sokuthi ukulahlekelwa kwe-argon akukhulu kuno-3% iminyaka engu-10. Lokhu kusho ukuthi eminyakeni engu-10 ngeke silahlekelwe ngaphezu kuka-3% kwe-argon, futhi lokhu kulahlekelwa kuyinto engathi sína futhi ezimeni zangempela, i-argon idlula ingilazi.

Futhi kukhona okuhlukile lapho izibuko zigcwaliswa khona nge-krypton, kodwa lokhu kwenziwa uma kudingekile ukuze kutholwe ukwahlukanisa okungcono ngezingilazi ezizacile, kodwa lokho ngeke kube isihloko sethu manje.

Sizonaka le nhlanganisela yengilazi.  Ngakho 4+16+4 LOW-E SOFT FILM. Inani layo lingu-Ug-1.1. Lokhu kusho ukuthi ebusika, 22% wokushisa uya ngaphandle, esikhundleni sokuthi 56%, kodwa ehlobo, 63% wokushisa kungena. Ukuthuthukiswa okukhulu kunengilazi ye-iso evamile, kodwa ukushintsha okuncane ku-g factor.

Imithetho lapha kakhulukazi isekelwe kunani lika-Ug, elisho ukulahlekelwa ukushisa ebusika, kodwa abantu ngokuqinisekile bafuna ukunethezeka kokusetshenziswa ehlobo, lapho bengafuni khona ukushisa kungene egumbini. Ngakho-ke, i-SOLAR 4+16+4 FLOT yenziwe, lapho izici zahlala zifana nokuthi 4+16+4 LOW-E SOFT FILM yehliselwa ekamelweni lokushisa ehlobo, kodwa i-LOW-E SOFT FILM ibe yindawo yokushisa yasehlobo. 42%. Lona umkhawulo ophansi esizindeni sezingilazi ezibonisa ngale. Konke okunye ukuncishiswa nokuthuthukiswa kwezici ze-Ug no-g kuqala ukuvela ekukhanyeni kwengilazi (eyaziwa nangokuthi ingilazi engafakwanga). Le nhlanganisela iyinhlanganisela yekhwalithi ephezulu kakhulu yezingilazi ezibonisa ngale, neqiniso lokuthi sisenezendlalelo ezimbili zengilazi.

Ingilazi enezingqimba ezintathu

Kancane kancane sifinyelela esiphethweni, futhi ngeke asekele umakhelwane ocebile othi, “Ngibeka amafasitela acwebezelwe kathathu abiza kakhulu endlini yami. Akutholi lutho olungcono kunalokho.”

Isithombe5 - Iphethini yefasitelana lamafasitelana amathathu

Asibuyele etafuleni1_ futhi ake sibheke amanani ingilazi enezingqimba ezintathu. Kuthi Ugh-1.8kanye noMnu-1.7, futhi sizuze ngesendlalelo esikabili1.3futhi1.1futhi ngemali encane kakhulu, ngoba ingilazi enjalo ishibhile kunengilazi enezingqimba ezintathu.

Senzeni ngokucwebezela kathathu? Senze iwindi/umnyango waba nzima kakhulu, sakhuphula intengo…..futhi senza umkhiqizo waba mubi kakhulu.

Linda. Ingabe ifilimu ethambile, i-argon, njll. ingangezwa lapha futhi?

Ingakwazi. Uma sithatha4+16I-Argon+4+16+4I-LOW-E. Kulokhu sizothola u-Ug-0,8futhi isici sika-g sicishe sifane60%(akukho okukhethekile).

Ukuthuthukiswa okuphezulu ngezingilazi ezinezendlalelo ezintathu, esingazithola, kuyinhlanganisela yalokhu:

Ilanga4+16I-Argon+4+16+4I-LOW-E. Bese sithola u-Ug-0.6, futhi iphesenti lokufaka ukushisa lingezansi40%.

Asiqhubekele ku…

Isiphetho:

Uma ufunde ngokucophelela umbhalo odlule futhi walandela ithebula lamanani ezinto ngokuhambisana, isiphetho sizobe sesicwebezela kwenye indawo, mayelana nayo yonke indaba emayelana nezibuko.

Ingilazi ekhishwa kancane enezendlalelo ezimbili, enefilimu ethambile, egcwele i-argon iyinhlanganisela engcono, futhi ethengekayo kakhulu, kunengilazi evamile enezendlalelo ezintathu. Inzuzo eyengeziwe ithi i-sash ekhanyayo, enweba impilo yewindi.

Leli qiniso lidala ukungabaza phakathi kwabantu ekuqaleni, nalabo abangabuqondi ubuchwepheshe bokukhiqiza ingilazi (futhi abasaqonda yonke into), bawela kalula engxoxweni emnandi yabantu umsebenzi wabo owukunciphisa uhlu lwamasheya.

Yebo, kodwa kukhona nezingilazi zezendlalelo ezintathu ezinenhlanganisela ethile zinikeza izici ezingcono kune-4+16+4LOW-E SOFT FILM!?

Yebo, zikhona. Zikhona, kodwa intengo yazo iphakeme ngokungenakuqhathaniswa kunalokho izibuko ezinjalo ezikwazi ukukunikeza, futhi lelo phuzu. Singasho ukuthi ezimweni ezinjalo intengo yengilazi (m2) ikhuphuka kakhulu ngokuhlobene nekhwalithi etholiwe.

Thola 4+16+4LOW-E SOFT FILM!

P.S.

Ungamangala ngeqiniso:

Ngeke ukwazi ukuzihlolela ukuthi iyiphi ingilazi oyitholile! Kukhona umtshina wengilazi okwazi ukubona uma unengilazi ecwebezelisiwe kabili noma ingilazi yeprimiyamu enefilimu, kodwa kubiza ama-euro angamakhulu ambalwa/izinkulungwane. Kukhona indlela engenziwa elabhorethri, kodwa ubani omunye oqale athathe iwindi aliyise elabhorethri, akhokhe inani lokuhlolwa, bese elifaka endlini noma efulethini.

Sizozivikela ngokukhetha inkampani efakazelwe futhi eyaziwayo esisebenzisana nayo, ngoba ayikhokhi ukudlala ngokuzethemba. Akufanelekile ukuthi amaphoyisa okwakha e-Austria ayale ukuthi asuse amafasitela ezakhiweni noma aguqule uhlelo oluvele lusungulwe lokukhiqiza nokufakwa.

Uma ukhetha ingilazi yendawo entsha yokuhlanganisa, bheka amafasitela ezingodo, amafasitela okhuni-aluminium noma thumela ubukhulu bekhwothi kithi.
