Xyoo 1994 tshiab rau insulated glazing yog evacuated iav, uas yog tseem ua lag luam hauv Nyij Pooj Tebchaws thiab China.The huab thinness heev ntawm cov hluav taws xob muaj yeeb yaj kiab muaj ntau ntau yam tshiab hauv cov qauv vaj tse, tshwj xeeb yog hauv kev txuag thiab kev tsim vaj tse, ib qho glazing, uas yog tsawg zog-npaum.
Ib qho hluav taws xob uas muaj qhov thaiv tau los ntawm kev sib khi ntawm ob lub iav nplooj, feem ntau los ntawm kev siv ib lub khob muag-iav, thiab khiav tawm hauv qhov chaw nrog lub tshuab nqus tsev vacuum.The evacuated chaw nruab nrab ntawm ob nplooj ntawv yuav ntiav heev thiab tseem ua tau zoo insulator, yielding insulative qhov rai nrog nominal thicknesses li tsawg li 6 hli zuag qhia tag nrho.Qhov vim li cas qhov no tsis tshua muaj tuab yog deceptively complex, tab sis lub rwb thaiv tsev zoo yog qhov tseem ceeb vim tias muaj peevxwb tsis muaj kev sib txuam lossis ua txoj hauv kev xa khoom hauv lub tshuab nqus tsev.
Hmoov tsis, evacuated glazing puas muaj qee qhov tsis zoo; nws cov khoom siv yog ib qho nyuab nyuab heev.Piv txwv li, tsim nyog theem ntawm cov khoom siv evacuated glazing yog outgassing; uas yog, cua sov nws kom tsis pub muaj cov roj adsorbed rau sab hauv cov sab, tom qab khiav dim thiab rhuav tshem lub tshuab nqus tsev.This cua sov txheej txheem tam sim no txhais tau hais tias kev khiav hluav taws xob tsis tuaj yeem ua rau muaj hluav taws xob-tau lossis cua sov-muaj zog. Yog tias lub iav thaiv kev nyab xeeb yuav tsum muaj, iav yuav tsum tau laminated.Qhov siab kub hnyiab rau outgassing kuj yuav ua kom puas zoo heev "mos" uas tsis tshua muaj-emissivity coatings uas feem ntau siv rau ib los yog ob qho tib si ntawm qhov chaw sab nraud (piv txwv li cov uas tig rau qhov sib txawv ntawm huab cua) ntawm lwm cov qauv ntawm niaj hnub insulative glazing, thiaj li tiv thaiv kev poob cua sov ntawm infrared radiatio -n . Tsis tshua zoo heev "nyuaj" coatings yog tseem haum rau evacuated glazing, txawm li ntawd los.
Tsis tas li ntawd xwb, vim tias qhov atmospheric siab tam sim no nyob rau sab nraud ntawm cov chav tsev thaiv, nws ob daim iav yuav tsum nyob sib nrug sib nraus kom tiv thaiv tau lawv ua ke thiab sib kov, uas yuav kov tau qhov khoom ntawm evacuating unit. ntawm tuav lub laujkaub-sib nrug yog ua los ntawm ib kab sib chaws ntawm lub nruab nrab, uas feem ntau muaj me ntsis stainless hlau discs uas muab tso rau ntawm 20 hli sib nrug.Lub nruab nrab yog cov tsawg txaus uas lawv pom tsuas yog nyob ze ze ntawm dia -nces, feem ntau mus rau 1 m. Txawm li cas los xij, qhov tseeb hais tias lub nruab nrab yuav ua rau qee lub cua sov ua rau muaj huab cua txias txias rau qhov tsim muaj ib ntus, daim phiaj sib npaug ntawm ib lub qhov ciav hlau, uas muaj ob lub voj voos me me ntawm qhov chaw nruab nrab, yog me ntsis txias tshaj qhov nruab nrab, los yog, thaum muaj dew sab nraum, lub voj voos me me ntawm sab nrauv ntawm iav, qhov twg lub lwg tsis tuaj vim hais tias lub pob zeb ua rau iav nyob ze lawv kom sov me ntsis.
Txoj kev kho cua sov ntawm lub tsho, vim los ntawm spacers, nyhav los txo cov glazin glazin 's tag nrho insulative effectiveness.Tiam sis, evacuated glazing yog tseem insulative li ntau thicker pa ob glazing thiab nyhav kom muaj zog, txij li ntawm ob tog puv iav los xij yog nias ua ke los ntawm qhov chaw, thiab ua li hnov mob ua ib daim ntawv tuab tuab rau khoov rog. Evacuated glazing kuj muaj suab nrov zoo nkauj nyob rau hauv kev sib piv nrog lwm cov hom nrov ntawm qhov rais glazing.
