Thermal rwb thaiv tsev coefficient ntawminsulating iav(feem ntau qhia los ntawm tus nqi K lossis U tus nqi) tsis yog tus nqi ruaj khov thiab nws txawv heev nyob ntawm kev teeb tsa ntawm lub khob. Hauv cov ntsiab lus yooj yim: Qhov qis dua tus nqi K, qhov zoo dua qhov kev ua haujlwm ntawm cov cua sov.
1. Ordinary dawb iav insulating iav
Qhov no yog qhov yooj yim tshaj plaws configuration ntawm insulating iav, muaj ob tug zoo tib yam ntab iav los xij thiab ib txheej insulating nyob nruab nrab ntawm.
Qauv: 5 hli iav + 12 hli insulating txheej + 5 hli iav (feem ntau sau ua 5+12A+5)
Thermal rwb thaiv tsev coefficient (K tus nqi): kwv yees li 2.8 txog 3.0 W / (m²·K)
Kev Ntsuam Xyuas: Qhov no yog tam sim no hom ntau tshaj plaws ntawm kev ua lag luam. Nws cov hluav taws kub rwb thaiv tsev kev ua tau zoo yog qhov nruab nrab thiab nws tuaj yeem ua tau raws li qhov xav tau tshwj xeeb tshaj plaws ntawm kev txuag hluav taws xob.
2. Tib-silver Low-E insulating iav (ib zaug- txheej qis- emissivity coated iav)
Qhov no tam sim no yog qhov kev teeb tsa tseem ceeb ntawm lub zog-cov vaj tsev zoo. Txheej tsawg- emissivity zaj duab xis nyob rau sab hauv ntawm ib daim iav tuaj yeem cuam tshuam deb -infrared tshav kub lub zog thiab txhim kho nws cov rwb thaiv tsev kub zoo heev.
Qauv: 5mm Low-E iav + 12mm argon gas + 5mm dawb iav
Thermal rwb thaiv tsev coefficient (K tus nqi): Nws tuaj yeem txo mus rau 1.4 txog 1.8 W / (m²·K).
Kev ntsuam xyuas: Qhov kev ua tau zoo ntawm cov rwb thaiv tsev kub yog ze li ob npaug ntawm cov iav insulating zoo tib yam, nrog rau kev ua haujlwm siab. Nws yog thawj qhov kev xaiv rau lub zog-txuag qhov rooj thiab qhov rais.
3. Ob npaug -silver/triple-silver Low-E insulating iav
Raws li ib qho nyiaj qis -E, nws muaj ntau txheej txheej thiab ua haujlwm tau zoo dua. Thaum ua kom ntseeg tau lub teeb pom kev zoo, nws kuj muaj cov rwb thaiv tsev kub dua thiab kev tiv thaiv hnub ci.
Qauv: Ntau cov iav coated + insulating txheej
Thermal rwb thaiv tsev coefficient (K tus nqi): Nws tuaj yeem ncav cuag 1.0 txog 1.4 W / (m²·K)
Kev ntsuam xyuas: Nws yog rau siab -kev ua tau zoo zog- txuag iav thiab feem ntau yog siv hauv cov tsev uas muaj lub zog siab - txuag cov kev xav tau.
4. Ua kom muaj cov txheej txheem hollow los yog sau cov roj
Cov nyhuv rwb thaiv tsev tuaj yeem txhim kho ntxiv los ntawm kev ntxiv cov txheej hollow (ua rau hauv peb- iav ob- kab noj hniav) los yog los ntawm kev sau cov txheej hollow nrog cov roj ntau inert tshaj huab cua (xws li argon lossis krypton).
Peb- iav ob- kab noj hniav ( iav dawb): K tus nqi tuaj yeem ncav cuag kwv yees li 2.0 W / (m²·K)
Peb -iav ob-chamber (ob npaug qis-E + ntim nrog cov roj inert): Tus nqi K tuaj yeem qis li 0.7 txog 1.0 W / (m²·K) lossis qis dua.
Kev ntsuam xyuas: Qhov no yog tus qauv teeb tsa rau cov tsev tsis muaj zog thiab ultra- lub tsev siv hluav taws xob tsawg, nrog rau kev ua haujlwm kub zoo heev.
Yam tseem ceeb cuam tshuam
Hom iav: Txawm tias qis-E txheej siv yog qhov tseem ceeb tshaj plaws cuam tshuam rau tus nqi K.
Hollow txheej roj: Sau nrog cov roj inert (xws li argon) tuaj yeem txo tus nqi K los ntawm kwv yees li 0.2-0.3 piv rau huab cua ntshiab.
Qhov dav ntawm txheej hollow: Feem ntau, 12mm txog 16mm yog tus nqi tshaj plaws - siv dav. Yog tias nws dav dhau los yog nqaim dhau, nws yuav cuam tshuam rau convection thiab txo cov nyhuv.
Sov-ntug spacer bars: Siv sov- ntug spacer tuav nrog qis thermal conductivity (xws li TPS, stainless steel spacer tuav) es tsis txhob siv cov txhuas txhuas spacer tuav tuaj yeem txhim kho qhov teeb meem condensation ntawm iav npoo thiab me ntsis nce tus nqi K tag nrho.
