Iglasi yenye yezona zinto zithandwayo kunye nezinto ezahlukeneyo zokwakha ezisetyenzisiweyo namhlanje, ngenxa yenxalenye yokuphuculwa kokusebenza kwelanga kunye nobushushu. Enye indlela eya kuphunyezwa ngayo le ntsebenzo kukusetyenziswa kokungasebenzi kunye nolawulo lwelanga ukutyabeka okungaphantsi. Ke yintoni iglasi ephantsi? Kweli candelo, sikubonelela ngesishwankathelo esinzulu sokugquma.
Ukuze uqonde ukutyabeka, kubalulekile ukuqonda amandla elanga okanye amandla avela elangeni. Ukukhanya kwe-Ultraviolet (UV), ukukhanya okubonakalayo kunye nokukhanya kwe-infrared (IR) zonke zihlala kwiindawo ezahlukeneyo zelanga - umahluko phakathi kwezi zintathu ugqitywa bubude bayo.
• Ukukhanya kwe-ultraviolet, yiyo loo nto ibangela ukuba izinto zangaphakathi ezinje ngamalaphu nezinto zokugquma eludongeni zitshabalale, zinobude obungu-310-380 weenanometer xa kunikwa ingxelo ngeglasi.
• Ukukhanya okubonakalayo kuhlala kwinxalenye yesibuko esiphakathi kwamaza amaza ukusuka kwii-nanometer ezingama-380-780.
• Ukukhanya kwe-infrared (okanye amandla obushushu) kudluliswa njengobushushu kwisakhiwo, kwaye kuqala kubude obude bama-780 ee-nanometer. I-infrared yelanga ibizwa ngokuba ngamandla amancinci e-infrared infrared, ngelixa ubushushu obuphuma kwizinto ezishushu bunemilinganiselo ephezulu yelanga kwaye kubhekiswa kuyo njenge-infrared long-wave.
Izambatho ze-Low-E ziye zaphuhliswa ukunciphisa inani le-ultraviolet kunye nokukhanya kwe-infrared okungadlula kwiglasi ngaphandle kokuthintela inani lokukhanya okubonakalayo okuhanjiswayo.
Xa ubushushu okanye ukukhanya kwamandla kuthathwa ngeglasi, kusenokwenzeka ukuba kushenxiswe kude ngokuhamba komoya okanye kubuyiswe kwakhona ngumgangatho weglasi. Ukukwazi kwezinto ezibonakalayo ukukhupha amandla kuyaziwa ngokuba ngumsebenzi. Ngokubanzi, izinto ezibonakalisa kakhulu zine-emissivity ephantsi kwaye izinto ezimnyama ezinemibala emnyama zinobungqina obukhulu. Zonke izinto, kubandakanya iifestile, zitshisa ubushushu ngohlobo lwelungu elide, amandla e-infrared ngokuxhomekeke kubume kunye nobushushu beendawo zabo. Amandla emitha yenye yeendlela ezibalulekileyo zokudlulisa ubushushu ngeefestile. Ukunciphisa ukungabikho komntu omnye okanye nangaphezulu kweefestile zeglasi kuphucula iipropathi zokukhusela ifestile. Umzekelo, iglasi engavutyelwanga ine-emissivity ye-.84, ngelixa i-Vitro Architectural Glass '(eyayisaziwa ngokuba yi-PPG glass) Solarban® Iglasi ye-70XL ine-emissivity ye .02.
Kulapho ukutyabeka okuphantsi (okanye iglasi ephantsi) kudlala khona. Iglasi ye-Low-E ine-microscopic thin, enamathela ebonakalayo-icekeceke kakhulu kunenwele yomntu-ebonisa amandla e-infrared infrared (okanye ubushushu). Ezinye ii-low-e's zikwabonisa isixa esibonakalayo samandla elitha yethoni yelanga efutshane. Xa amandla obushushu angaphakathi azama ukubaleka aye kubanda ngaphandle ngexesha lobusika, isambatho esisezantsi-e sibonisa ubushushu buyela ngaphakathi, sinciphise ilahleko ebushushu eglass. Ukuchasana kwenzeka ngexesha lasehlotyeni. Sebenzisa umlinganiso olula, iglasi ephantsi isebenza ngendlela efanayo ne-thermos. I-thermos ine-lining yesilivere, ebonisa ubushushu besiselo esinaso. Iqondo lobushushu ligcinwa ngenxa yokubonakaliswa okungagungqiyo okwenzekayo, kunye nezibonelelo zokugquma ezibonelelwa sisithuba somoya phakathi kweqokobhe langaphakathi nangaphandle le-thermos, efanayo neyunithi yeglasi yokugquma. Kuba iglasi esezantsi-e inezinto ezincinci zesilivere okanye ezinye izinto eziphantsi zokuzonwabisa, ithiyori efanayo iyasebenza. Isinxibo esisezantsi-e sibonisa ubushushu bangaphakathi ngaphakathi ngaphakathi, ukugcina igumbi lifudumele okanye libanda.
Iindidi zokuThwala ezantsi kunye neenkqubo zoveliso
Kukho iindidi ezimbini ezahlukeneyo zokwaleka kwe-e ephantsi: i-passive low-e yokwaleka kunye nolawulo lwe-solar low-e. I-passive low-e yokwaleka yenzelwe ukwandisa ubushushu belanga kwikhaya okanye kwisakhiwo ukwenza ifuthe lokufudumeza "okwenzekileyo" kunye nokunciphisa ukuthembela kumbane wobushushu. Ulawulo lweSolar low-e ukutyabeka kuyilelwe ukunciphisa umda wobushushu belanga obungena kwikhaya okanye kwisakhiwo ngenjongo yokugcina izakhiwo zipholile kunye nokunciphisa ukusetyenziswa kwamandla okunxulumene nemeko yomoya.
Zombini ezi ntlobo zeglasi ephantsi, ulawulo lwamandla kunye nelanga, ziveliswa ngeendlela ezimbini eziphambili zemveliso- ipyrolytic, okanye "idyasi enzima", kunye neMagnetron Sputter Vacuum Deposition (MSVD), okanye "idyasi ethambileyo". Kwinkqubo ye-pyrolytic, eyayiqhelekile ebutsheni beminyaka yee-1970, kwalekwa kufakwa iribhoni yeglasi ngelixa yayisenziwa kumgca wokudada. Ukutyabeka emva koko "kufayiza" kumphezulu weglasi oshushu, kudala uxhulumaniso olomeleleyo nolomelele kakhulu ekulungisweni kweglasi ngexesha lolwakhiwo. Okokugqibela, iglasi iyasikwa kwiimakhishithi ezinobungakanani obahlukeneyo bokuthunyelwa kubenzi. Kwinkqubo yeMSVD, eyaziswa ngeminyaka yoo-1980 kwaye iqhubeka isulungekiswa kumashumi eminyaka akutshanje, ukutyabeka kufakwa ngaphandle komgca kwiglasi yokusika kwangaphambili kwigumbi lokucoca kwigumbi lobushushu begumbi.
Ngenxa yokuvela kwembali kwezi teknoloji zokwaleka, maxa wambi i-e-e yokuhombisa ngamanye amaxesha inxulunyaniswa nenkqubo ye-pyrolytic kunye nolawulo lwe-solar low-e nge-MSVD, nangona kunjalo, oku akusasebenzi ngokuchanekileyo. Ukongeza, ukusebenza kuyahluka kakhulu ukusuka kwimveliso ukuya kwimveliso kunye nomenzi ukuya kumenzi (jonga kwitheyibhile engezantsi), kodwa iitafile zedatha yokusebenza ziyafumaneka ngokulula kwaye izixhobo ezininzi ezikwi-Intanethi zinokusetyenziselwa ukuthelekisa zonke izinto zokunxiba ezisezantsi kwimarike.
Ukwaleka Indawo
Kwiphaneli esezantsi esezantsi ye-IG kukho iindawo ezine ezinokubakho ezinokuthi zisetyenziswe kuzo: Zahlulwe ngeplipheral spacer eyenza indawo yokufudumeza umoya, ngelixa eline (# 4) umphezulu ujongene ngqo ngaphakathi. Ukutyabeka okuphantsi e-e kusebenza kakuhle xa kubuso besithathu okanye besine (kude nelanga), ngelixa amandla elanga e-e-e egqume ukusebenza kakuhle xa ikwi-lite ekufutshane nelanga, ubukhulu becala umphezulu wesibini.
Amanyathelo okuSebenza oMdaka ophantsi
Izambatho ezisezantsi-e zisetyenziselwa imiphezulu eyahlukeneyo yeeyunithi zeglasi zokugquma. Nokuba isambatho esisezantsi-e sithathwa njengesiqhelo okanye ulawulo lwelanga, zibonelela ngophuculo kumaxabiso entsebenzo. Oku kulandelayo kusetyenziselwa ukulinganisa ukusebenza kweglasi ngee-e-e-pearlings:
• Ixabiso le-U linqanaba elinikwe iwindow ngokubhekisele kubungakanani bokulahleka kobushushu okuvumelayo.
• UkuKhanya kokuKhanya okuBonakalayo linyathelo lokukhanya okungakanani okudlula ngefestile.
• Ubushushu beSola buzuza ukungalingani sisiqwengana sesiganeko imitha yelanga eyamkelweyo ngefestile, zombini zigqithiselwe ngokuthe ngqo kwaye zifunxiwe kwaye ziphinde zenziwe imitha ngaphakathi. Ezantsi ifestile yelanga yokufumana ubushushu bokulingana, ubushushu belanga obuncinci buhambisa.
• UkuKhanya ukuya kwiLanga ngumlinganiso ophakathi kwefestile yeSolar Heat Gain Coefficient (SHGC) kunye nokukhanya kwayo kokukhanya kokukhanya (VLT).
Nantsi indlela yokulinganisa ukulinganisa ngokunciphisa inani le-ultra-violet kunye ne-infrared light (amandla) anokudlula ngeglasi ngaphandle kokunciphisa inani lokukhanya okubonakalayo okuhanjiswayo.
Xa ucinga yoyilo lwefestile: ubungakanani, ukubala kunye nezinye iimpawu zobuhle ziza engqondweni. Nangona kunjalo, ukuhonjiswa okuphantsi kwe-e kudlala indima ebaluleke ngokulinganayo kwaye kuchaphazela ngokubonakalayo ukusebenza kwefestile kunye nokufudumeza, ukukhanya, kunye neendleko zokupholisa zesakhiwo.
