Tsawg-e Iav Ua Haujlwm Li Cas

Iav yog qhov nrov tshaj plaws thiab ntau yam khoom siv hauv tsev siv niaj hnub no, vim qee ntu rau nws tas li txhim kho lub hnub ci thiab thermal ua haujlwm. Ib txoj hauv kev ua tiav no yog ua tiav los ntawm kev siv hluav taws xob passive thiab hnub ci qis-e txheej. Yog li, dab tsi yog qis-e iav? Hauv seem no, peb muab rau koj kom pom qhov tob pom ntawm txheej xim.

Txhawm rau kom nkag siab txog txheej txheej txheej, nws tseem ceeb kom nkag siab txog lub hnub ci zog hluav taws xob lossis lub zog ntawm lub hnub ci. Ultraviolet (UV) lub teeb, pom lub teeb thiab infrared (IR) lub teeb txhua tus nyob hauv ntau qhov chaw ntawm lub hnub ci ci xim - qhov sib txawv ntawm peb yog txiav txim siab los ntawm lawv cov wavelengths.

Glass is one of the most popular and versatile building materials used today, due in part to its constantly improving solar and thermal performance. One way this performance is achieved is through the use of passive and solar control low-e coatings. So, what is low-e glass? In this section, we provide you with an in-depth overview of coatings.

• Lub teeb ci ultraviolet, uas yog qhov ua rau cov khoom siv sab hauv xws li cov ntaub thiab cov npog phab ntsa kom ploj, muaj nthwv dej ntawm 310-380 nanometers thaum qhia txog kev ua haujlwm iav.

• Lub teeb pom kev pom nyob ntawm ib feem ntawm lub spectrum ntawm wavelengths los ntawm txog 380-780 nanometers.

• Lub teeb ci (los yog lub zog cua sov) kis tau thaum cua sov mus rau hauv ib lub tsev, thiab pib ntawm wavelengths ntawm 780 nanometers. Hnub ci infrared feem ntau hu ua luv luv yoj infrared zog, thaum tshav kub tawg ntawm cov khoom sov tau muaj lub siab ntev dua li lub hnub thiab xa mus rau qhov ntev-ntev infrared.

Cov txheej txheem qis-E tau tsim los txo qhov tsawg ntawm ultraviolet thiab duab ci ci uas tuaj yeem hla iav tau yam tsis muaj kev cuam tshuam qhov ntau ntawm qhov pom pom uas kis tau.

Thaum kub los yog lub teeb lub zog yog nqus los ntawm iav, nws yog hloov chaw los ntawm kev txav cov cua los yog rov kis los ntawm cov iav saum npoo. Lub peev xwm ntawm cov khoom siv rau radiate zog yog lub npe hu ua emissivity. Nyob rau hauv dav dav, cov ntaub ntawv muaj kev cuam tshuam muaj qhov tsawg emissivity thiab npub tsaus cov xim cov ntaub ntawv muaj qhov siab emissivity. Txhua yam khoom siv, suav nrog cov qhov rai, hluav taws xob kub hauv daim ntawv ntawm lub suab yoj ntev, infrared zog nyob ntawm emissivity thiab qhov kub ntawm lawv qhov chaw. Lub zog muaj hluav taws xob yog ib txoj hauv kev tseem ceeb ntawm kev hloov cua sov tshwm sim nrog lub qhov rais. Txo cov emissivity ntawm ib lossis ntau ntawm cov qhov rai iav chaw zoo txhim kho lub qhov rai lub insulating zog. Piv txwv li, iav tsis siv neeg muaj qhov sib txawv ntawm .84, thaum Vitro Architectural Glass '(yav tas los iav PPG) hnub ci Solarban® 70XL iav muaj qhov emissivity ntawm .02.

Qhov no yog qhov twg emissivity tsawg (los yog tsawg-e iav) lo lo ntxhuav tuaj mus ua si. Daim iav qis-E muaj qhov tsom me me, pob tshab xim - nws yog qhov ntau me dua li tib neeg cov plaub hau - uas qhia txog ntev ntev hluav taws xob infrared zog (lossis cua sov). Qee qhov qis-e's tseem cuam tshuam cov nuj nqis ntawm luv luv yoj hnub ci infrared zog. Thaum lub zog cua kub sab hauv sim kom khiav mus rau qhov chaw txias txias sab nraum zoov thaum lub caij ntuj no, txheej qis qis e qhia qhov cua sov rov qab mus rau sab hauv, txo cov hluav taws xob kub los ntawm iav. Qhov rov qab tshwm sim thaum lub caij ntuj sov. Txhawm rau siv cov lus sib piv yooj yim, qis-e iav ua haujlwm zoo ib yam li thermos. Ib cov thermos muaj ib lub ntsej muag nyiaj, uas qhia txog qhov kub ntawm cov dej haus nws muaj. Qhov kub yog tswj xyuas vim yog qhov kev cuam tshuam tas li uas tau tshwm sim, nrog rau cov txiaj ntsig insulating uas qhov chaw huab cua muab tau nruab nrab ntawm lub plhaub sab hauv thiab sab nraud ntawm cov thermos, zoo ib yam li cov iav insulating. Txij li thaum iav qis-e yog suav nrog cov tsis tshua muaj txheej nyias nyias ntawm cov nyiaj lossis lwm cov ntaub ntawv qis, qhov kev xav zoo ib yam. E-xim txheej xim thim ntsej muag sab hauv qhov kub thiab txias, ua rau chav sov lossis txias.

Tsawg-e Txheej Hom & Cov txheej txheem tsim khoom

Muaj tiag ob qho kev sib txawv ntawm qhov tsis tshua muaj kev tiv thaiv qis: passive low-e coatings thiab hnub ci qis-e txheej. Passive low-e coatings yog tsim los ua kom lub hnub ci sov ntau ntxiv rau hauv tsev lossis hauv tsev kom tsim tau cov txiaj ntsig ntawm kev ua kom muaj cua sov "ua kom tsis muaj zog" thiab txo kev cia siab rau cov cua kub cuav. Kev tswj hwm hnub ci qis qis e tau tsim los txwv cov nyiaj ntawm lub hnub ci ntau dua uas nkag mus rau hauv tsev lossis tsev tsim kom ua rau lub tsev nyob txias dua thiab txo kev siv hluav taws xob muaj feem xyuam nrog cua txias.

Ob hom qis-e iav, kev tswj ntsuas lub zog thiab hnub ci, yog tsim los ntawm ob hom kev pib ua khoom - pyrolytic, lossis "tsho tawv", thiab Magnetron Sputter Vacuum Deposition (MSVD), lossis "tsho tiv no muag". Hauv cov txheej txheem pyrolytic, uas tau dhau los ua qhov pib thaum xyoo 1970, txheej txheej yog thov rau cov pob zeb iav thaum nws tab tom tsim tawm ntawm cov kab ntab. Cov xim txheej tom qab ntawd "fuses" rau lub iav kub saum npoo, tsim kom muaj cov khoom sib zog uas ruaj khov rau cov iav ua thaum ua cov qauv. Thaum kawg, daim iav txiav rau hauv cov ntawv txheeb ntawm ntau qhov ntau thiab tsawg rau cov zaub mov xa tuaj rau cov ntaub. Hauv cov txheej txheem MSVD, qhia rau xyoo 1980 thiab txuas ntxiv txhim kho nyob rau xyoo tsis ntev los no, cov xim pleev tau thov tawm-cov kab rau kev txiav cov iav ua ntej hauv lub tshuab nqus tsev ntawm chav sov.

Manufacturing Processes

Vim tias qhov kev hloov pauv keeb kwm ntawm cov txheej txheem thev naus laus zis, passive low-e coatings qee zaum muaj feem cuam tshuam nrog cov txheej txheem pyrolytic thiab lub hnub ci qis qis qis e-txheej nrog MSVD, txawm li cas los xij, qhov no tsis muaj tseeb tag nrho. Tsis tas li ntawd, kev ua tau zoo sib txawv ntawm cov khoom lag luam mus rau cov chaw tsim khoom thiab cov chaw tsim tshuaj paus mus rau cov chaw tsim khoom (saib cov lus hauv qab), tab sis cov ntaub ntawv kev ua tau zoo muaj yooj yim thiab muaj ntau cov cuab yeej online yuav siv tau los sib piv tag nrho cov e-txheej qis hauv khw.

Txheej Thaj Chaw

Hauv lub vaj huam sib luag coj ua vaj huam sib luag IG muaj plaub qhov chaw muaj peev xwm siv tau rau cov xim txheej tuaj yeem siv: thawj (# 1) saum npoo sab nraum zoov, sab ob (# 2) thiab thib peb (# 3) sab ntsej muag sib xyaw hauv cov iav insulating thiab raug sib cais los ntawm tus ntsuas ntxig qhov txuas uas tsim qhov chaw huab cua insulating, thaum plaub (# 4) saum npoo tig ncaj qha rau sab hauv tsev. Passive low-e coatings ua haujlwm tau zoo tshaj plaws thaum nyob ntawm thib peb lossis thib plaub saum npoo (furthest tsis deb ntawm lub hnub), thaum lub hnub ci tswj qis-e txheej txheej ua haujlwm zoo tshaj plaws thaum nyob ntawm lub Lite ze rau lub hnub, feem ntau qhov saum npoo thib ob.

Tsawg-e Txheej Txheem Ntsuas Kev Ntsuas

Cov khoom siv qes-pleev xim tau thov rau ntau qhov chaw ntawm txheej txheem insulating iav. Txawm hais tias hom qes-e tau suav tias yog kev ntsuas siab los yog tiv thaiv hnub ci, lawv muab cov kev txhim kho hauv cov txiaj ntsig kev ua tau zoo. Hauv qab no yog siv los ntsuas qhov ua tau zoo ntawm iav nrog qis-e txheej:

• U-Tus Nqi yog qhov ntaus nqi muab rau lub qhov rais raws li qhov cuam tshuam kub npaum li cas nws tso cai.

• Pom Kev Sib Hloov yog qhov ntsuas ntawm ntau npaum li cas lub teeb dhau los ntawm lub qhov rais.

• Hnub ci Kub Tshav Kub Tau yog qhov feem ntawm cov xwm txheej hnub ci hluav taws xob lees paub los ntawm lub qhov rais, ob leeg ncaj qha kis thiab nqus & rov nkag sab hauv. Qhov qis dua ntawm lub qhov rais hnub ci tshav kub nce coefficient, tsawg lub hnub ci tshav kub nws kis.

• Lub Teeb rau Hnub Ci Kev nce yog qhov sib piv ntawm lub qhov rais hnub ci Kev Tshav Kub Txais Cov Hluav Taws Xob (SHGC) thiab nws qhov pom kev sib kis (VLT).

Ntawm no yog li cas cov kev co yuav ntsuas tau los ntawm kev txiav cov nyiaj ntawm ultra-violet thiab duab teeb ci (lub zog) tuaj yeem hla dhau iav yam tsis muaj kev cuam tshuam qhov muag pom ntawm lub teeb uas kis tau.

Performance Measures

Thaum xav qhov rai tsim: qhov loj me, zas thiab lwm yam zoo nkauj tuaj rau hauv siab. Txawm li cas los xij, qis-e txheej txig ua lub luag haujlwm sib luag thiab cuam tshuam rau txhua yam kev ua haujlwm ntawm lub qhov rais thiab tag nrho cov cua sov, teeb pom kev zoo, thiab cov nqi txias ntawm lub tsev.
