Low-emissivity (low-e) iav yog ib hom iav uas muaj ib qho microscopically nyias, pob tshab txheej siv rau nws qhov chaw. Cov txheej no yog tsim los txo cov cua sov hloov mus los ntawm cov iav thaum tso cai rau pom lub teeb kom dhau mus. Nov yog qee qhov tshwj xeeb tseem ceeb thiab cov yam ntxwv ntawm low-e iav:
1.Thermal rwb thaiv tsev: Tsawg-e iav pab txhim kho cov thermal rwb thaiv tsev ntawm lub tsev los ntawm kev txo cov cua sov. Cov txheej qis-e qhia txog ib feem tseem ceeb ntawm lub zog ntev-yoj infrared (kub) rov qab mus rau nws qhov chaw, txawm tias yog sab hauv lossis sab nrauv ntawm lub tsev. Qhov no pab ua kom lub tsev nyob sab hauv kom txias hauv cov huab cua kub lossis sov sov hauv cov huab cua txias, ua rau muaj zog ua kom muaj zog thiab txo cov nqi cua sov thiab cua txias.
2. Solar Heat Gain Control: Low-e iav kuj tseem tuaj yeem muab kev tswj hwm hnub ci tshav kub los ntawm kev xaiv thaiv ib feem ntawm lub hnub ci hluav taws xob. Qhov no yuav pab txo qis cov hnub ci cua sov uas nkag mus rau hauv lub tsev, yog li tiv thaiv overheating thiab txo qhov kev cia siab ntawm cov tshuab cua txias.
3. Pom pom lub teeb kis tau tus mob: Low-e iav yog tsim los tswj cov qib siab ntawm cov teeb pom kev zoo, tso cai rau lub hnub ci ntuj nkag mus rau hauv lub tsev. Qhov no yuav pab tsim kom muaj qhov ci ntsa iab thiab xis nyob hauv ib puag ncig thaum txo qhov xav tau ntawm cov teeb pom kev zoo thaum nruab hnub.
4. U-Value: U-tus nqi ntawm qis-e iav ntsuas nws tag nrho cov thermal conductivity lossis kub hloov coefficient. Qhov qis dua U-tus nqi qhia tau hais tias zoo dua cov khoom rwb thaiv tsev. Low-e iav feem ntau muaj qis dua U-tus nqi piv rau cov iav ntshiab tsis tu ncua, pab txo kom sov los yog nce los ntawm qhov rais.
5. SHGC (Solar Heat Gain Coefficient): Lub SHGC ntawm cov iav qis-e sawv cev rau feem ntawm lub hnub ci tshav kub uas kis tau los ntawm iav. Ib qho qis SHGC qhia tau hais tias lub hnub ci tswj tau zoo dua. Low-e iav muaj nyob rau hauv ntau qhov sib txawv, tso cai rau kev hloov kho ntawm SHGC kom haum rau cov xwm txheej tshwj xeeb thiab cov hom phiaj siv hluav taws xob.
6. Txheej Txheej: Cov txheej txheem qis-e tuaj yeem siv rau qhov sib txawv ntawm cov iav, nrog rau sab hauv lossis sab nrauv, lossis nyob nruab nrab ntawm ntau txheej iav hauv chav tsev insulated iav (IGU). Qhov kev tso kawm ntawm cov txheej txheem qis-e cuam tshuam rau nws qhov kev ua tau zoo thiab tuaj yeem xaiv raws li cov xwm txheej xws li kev nyab xeeb, kev taw qhia ntawm lub tsev, thiab cov yam ntxwv ntawm kev ua haujlwm.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov yam ntxwv tshwj xeeb ntawm cov iav qis-e tuaj yeem sib txawv nyob ntawm cov chaw tsim khoom, hom khoom, thiab txheej tshuab siv. Kev sab laj nrog cov tuam txhab iav lossis cov neeg muag khoom tuaj yeem muab cov ntaub ntawv ntxaws ntxiv ntawm cov lus qhia tshwj xeeb thiab kev ua tau zoo ntawm lawv cov khoom siv iav tshwj xeeb qis.
