Nekudaro, iyo gobvu IGU inopa matambudziko.Iyo gobvu unit inogadzirwa neLiteZone ine masere akamiswa mafirimu pakati pezvimedu zviviri zvegirazi.Kana nzvimbo dzese idzi dzakavharwa, pachave nedambudziko rekumanikidzana, saka LiteZone yakagadzira iyo unit ichishandisa inonzi naClarahan "pressure balance duct".Iyo idiki vent chubhu inogona kudzikamisa mhepo yemhepo mumakamuri ese nemhepo iri kunze kwemudziyo.Clarahan akataura kuti kamuri yekuomesera yakavakirwa muchubhu inodzivirira mhute yemvura kuti isaungane mukati memidziyo uye inogona kushandiswa nemazvo kweanenge makore makumi matanhatu.
Iyo kambani yakawedzera chimwe chimiro.Panzvimbo yekushandisa kupisa kuderedza firimu mukati memudziyo, vakagadzira gasket kumucheto kwechigadzirwa chinoita kuti firimu rirambe rakamira pasi pechiito chezvitubu zviduku.Clarahan akataura kuti nekuti iyo firimu haina kudziyisa, kushushikana kuri kushoma.Mahwindo airatidzawo kudzikamisa ruzha.
Firimu yakamiswa inzira yekudzikisa huremu hwema-multi-pane IGUs.Curcija akatsanangura chimwe chigadzirwa chinonzi "Thin Triple," icho chakwezva kutarisisa kwakapararira muindastiri.Iine girazi rakatetepa re 0.7 mm kusvika 1.1 mm (0.027 inches uye 0.04 inches) pakati pezvikamu zviviri zvekunze zve3 mm girazi (0.118 inches).Uchishandisa k-kuzadza, mudziyo unogona kurongedzerwa mu3⁄4-inch yakafara girazi bhegi, zvakafanana neyakajairwa kaviri-pane mudziyo.
Curcija akati iyo yakatetepa katatu ichangotanga kutora nzvimbo muUnited States, uye chikamu chayo chemusika chave pasi pe1%.Pavakatanga kutengeswa makore anodarika gumi apfuura, michina iyi yakatarisana nehondo yakaoma yekutambirwa kwemusika nekuda kwemitengo yakakwira yekugadzira.Corning chete ndiyo inogadzira girazi rakatetepa iro dhizaini rinotsamira pariri, pamutengo wemadhora masere kusvika gumi pagumbo rimwe.Mukuwedzera, mutengo we k unodhura, inenge 100 nguva yemutengo we argon.
Maererano naKursia, mumakore mashanu apfuura, pane zvinhu zviviri zvakaitika.Chekutanga, mamwe makambani egirazi akatanga kuyangarara magirazi matete achishandisa nzira yakajairika, yaive kugadzira girazi rehwindo pamubhedha werata rakanyungudutswa.Izvi zvinogona kuderedza mutengo kusvika kumasendi makumi mashanu paskweya tsoka, izvo zvakaenzana negiraziwo zvaro.Kuwedzera kwekufarira mumwenje we LED kwakonzera kuwedzera kwekugadzirwa kwexenon, uye zvinozoitika kuti k ndeye-chigadzirwa chechiitiko ichi.Mutengo wazvino uno ungangoita chikamu chechina chezvawaimbova, uye iyo yese premium yeatete matatu-layer katatu ingangoita $2 paskweya tsoka yeyakajairwa kaviri-glazed IGU.
Curcija akati: “Neraki yakatetepa ine matatu-tier, unogona kuwedzera kusvika paR-10, saka kana ukafunga mubhadharo wemadhora maviri paskweya tsoka, mutengo wakanaka kwazvo uchienzaniswa neR-4 nemutengo unonzwisisika.Kusvetuka kukuru. "Naizvozvo, Curcija anotarisira kufarira kwekutengesa kweMie IGU kuwedzera.Andersen akazvishandisa kune yayo Windows yekutengesa yekuvandudza mutsara.Ply Gem, mugadziri mukuru wemahwindo muUnited States, anoitawo seanofarira.Kunyangwe Alpen anoenderera mberi nekusimudzira zvakanakira mahwindo emufirimu akamiswa uye akawana mabhenefiti ezvishandiso zvemafirimu matatu.
Mark Montgomery, mutevedzeri wemutungamiri weUS hwindo rekushambadzira kuPly Gem, akati kambani parizvino inogadzira 1-in-1 zvigadzirwa.Uye 7⁄8 inch katatu.“Tiri kuyedza ne3⁄4-in.Akanyora muemail."Asi (isu) parizvino tinogona kuwana mazinga epamusoro ekuita.”
Usatsvaga shanduko yebatch kuita yakatetepa katatu ipapo.Asi Tanga akataura kuti girazi rakatetepa repakati iri nyore kugadzirisa pane rakamiswa firimu, rine mukana wekumhanyisa kugadzirwa, uye rinobvumira kushandiswa kweanodziya-kumucheto gaskets kutsiva yakasimba Stainless simbi gaskets inodiwa nemamwe akamiswa firimu IGUs.
Pfungwa yekupedzisira yakakosha.Iyo firimu yakamiswa iyo inodonha muchoto ichaita kushushikana kukuru pane peripheral gasket, iyo ichapwanya chisimbiso, asi girazi rakatetepa harifanirwe kutambanudzwa, nokudaro kuderedza dambudziko.
Curcija akati: "Mukuongorora kwekupedzisira, matekinoroji ese ari maviri anopa zvinhu zvakafanana, asi maererano nekusimba uye kunaka, girazi riri nani pane firimu."
Nekudaro, iyo matatu-layer sheet yakadhonzwa naLarsen haina tarisiro yakadaro.Makadhinari ari kugadzira mamwe eaya maIGU, asi mutengo wavo ungangoita zvakapetwa kaviri iwo echinyakare matatu-mu-rimwe girazi, uye iyo yekupedzisira-yakatetepa girazi iri pakati pemodule ine yakakwira yekuputsika.Izvi zvakamanikidza kadhinari kushandisa 1.6mm yepakati layer panzvimbo.
"Pfungwa yegirazi rakatetepa iri hafu yesimba," Larsen akadaro.“Uchatenga girazi rehafu-simba wotarisira kurishandisa muhukuru hwakafanana negirazi resimba rembiri?Aiwa. Kungoti mwero wedu wekubata kuputsika wakakwira zvakanyanya.
Akawedzera kuti kuonda-kuonda katatu kunosanganawo nezvimwe zvimhingamipinyi.Chikonzero chikuru ndechekuti girazi rakatetepa rakanyanya kutetepa kuti rirege kudzikamiswa, inova kurapa kwekupisa kuwedzera simba.Girazi rinodziya chikamu chakakosha chemusika, chinoverengera makumi mana muzana eCardinal's yakazara IGU yekutengesa.
Pakupedzisira, pane dambudziko rekuzadza gasi rerypto.Larson akataura kuti fungidziro yemitengo yaLawrence Berkeley Labs yakaderera, uye indasitiri yaita basa rakashata rekupa gasi rechisikigo rakakwana reIGU.Kuti ishande, 90% yenzvimbo yakavharwa yemukati inofanirwa kuzadzwa negasi, asi maitiro eindasitiri anotarisa kumhanya kwekugadzira kwete mhedzisiro chaiyo, uye chiyero chekuzadza gasi mune zvigadzirwa pamusika chinogona kunge chakaderera kusvika makumi maviri muzana.
"Pane zvakawanda zvekufarira mune izvi," Larson akadaro nezvevatatu-kuderedza uremu."Chii chinoitika kana ukangowana 20% yekuzadza level pamahwindo aya?Haisi R-8 girazi, asi R-4 girazi.Izvi zvakafanana kana uchishandisa dual-pane low-e.Une zvese zvandisina kuwana."
Ose ari maviri argon uye k gasi ari nani insulators kupfuura mhepo, asi hapana gasi rekuzadza (vacuum) richavandudza zvakanyanya kupisa kwemafuta, uye iyo R kukosha inogona iri pakati pe10 ne14 (U coefficient kubva 0.1 kusvika 0.07).Curcija akati ukobvu hweyuniti hwakatetepa segirazi-pani.
Mugadziri wekuJapan anonzi Nippon Sheet Glass (NSG) ari kutogadzira vacuum insulating glass (VIG) zvishandiso.Maererano naCurcija, vagadziri veChinese uye Guardian Glass yeUnited States vatangawo kugadzira R-10 VIG zvishandiso.(Takaedza kubata Guardian asi hatina kuwana mhinduro.)
Kune matambudziko ehunyanzvi.Chekutanga, musimboti wakabviswa zvakazara unokweva mativi maviri ekunze egirazi pamwechete.Kuti izvi zvisaitike, mugadziri akaisa tuma spacers pakati pegirazi kudzivirira kuti matinji asadonha.Idzi mbiru diki dzakapatsanurwa kubva kune imwe neimwe nechinhambwe che 1 inch kusvika 2 inches, zvichiita nzvimbo inosvika 50 microns.Kana iwe ukanyatsotarisisa, unogona kuona kuti iwo matrix asina simba.
