Lub thawv lub cev nws tus kheej yog ua los ntawm hlau, uas muaj thermal conductivity zoo heev. Yog tsis muaj kev ntsuas thermal rwb thaiv tsev zoo, cov teeb meem ntawm lub caij ntuj sov thiab lub caij ntuj no txias tsis tuaj yeem daws tau. Kev xaiv kom raug thiab kev tshawb fawb ntawm cov ntaub ntawv rwb thaiv tsev yog cov tseem ceeb lav rau ib puag ncig kev nplij siab ntawm lub tsev ntim khoom. Kab lus no, xa mus rau cov qauv kev lag luam, qhia txog cov khoom siv hluav taws xob tseem ceeb, kev xaiv thickness, tsim thermal tawg, thiab cov ntsiab lus tseem ceeb ntawm kev tsim kho.
1. Kev sib piv ntawm cov khoom siv rwb thaiv tsev tseem ceeb
Peb hom kev rwb thaiv tsev cov ntaub ntawv feem ntau yog siv hauv cov tsev ntim khoom niaj hnub no, txhua tus muaj nws qhov zoo thiab qhov tsis zoo:
| Khoom siv | Thermal conductivity (W / (m·K) | Kev ntsuas hluav taws | Qhov zoo | Qhov tsis zoo |
|---|---|---|---|---|
| Pob zeb ntaub plaub | <0.041 | Class A (tsis-combustible) | Kev ua haujlwm tua hluav taws zoo heev, kev tiv thaiv hluav taws kub siab | Tsawg heev noo noo nqus |
| Polyurethane (PU) | 0.022 | Feem ntau Class B2 | Zoo rwb thaiv tsev, seamless tsuag daim ntawv thov | Kev ntsuas hluav taws qis dua |
| Extruded polystyrene (XPS) | 0.028-0.039 | Chav B1 xaiv tau | Tsis tshua muaj dej nqus, zoo heev noo noo kuj | Poorer cua permeability |
| Airgel sib xyaw | 0.015-0.020 | Chav Kawm A | Ultra-nyias thiab siv tau, txuag chaw | Tus nqi siab dua |
| Lub tshuab nqus tsev rwb thaiv tsev (VIP) | 0.004-0.008 | Chav Kawm A | Kev ua tau zoo ntawm lub ntiaj teb kev rwb thaiv tsev | kim heev, tsis tuaj yeem txiav |
Pom zoo cov khoom siv siab heev: Ib qho airgel composite tsuas yog 3 cm tuab tuaj yeem ua tiav cov txiaj ntsig zoo ib yam li 10 cm ntawm cov khoom siv ib txwm siv, ua rau nws tshwj xeeb tshaj yog tsim rau qhov chaw ntim khoom kho dua tshiab.
2. Kev xaiv rwb thaiv tsev Thickness
Qhov tsim nyog rwb thaiv tsev thickness yuav tsum tau xam raws li kev nyab xeeb cheeb tsam ntawm qhov project qhov chaw. Cov qauv siv feem ntau hauv kev lag luam yogR = δ/λ(qhov R yog thermal tsis kam, δ yog cov khoom tuab, thiab λ yog thermal conductivity).
Cov cheeb tsam txias sab qaum teb: Pom zoo phab ntsa thickness ntawm 75-100 mm.
Kub lub caij ntuj sov thiab sov lub caij ntuj no cov cheeb tsam yav qab teb: Lub thickness ntawm 50 hli feem ntau yog txaus kom tau raws li qhov xav tau ntawm rwb thaiv tsev.
Rwb thaiv tsev: Ib txheej ob txheej staggered seam installation tuaj yeem txo qhov kub poob los ntawm thermal bridging.
3. Thermal Break Design and Key Construction Points
Kev tsim hluav taws xob tawg yog qhov tseem ceeb tshaj plaws hauv kev ua haujlwm rwb thaiv tsev - uas yog, muab cov ntaub qhwv insulating ntawm cov ncej hlau thiab cov khoom siv rwb thaiv tsev kom tiv thaiv cov khoom siv hlau los ntawm kev sib txuas ncaj qha rau sab hauv thiab sab nrauv, tsim txoj kev tshav kub.
Kev tsim kho tseem ceeb:
Txhua qhov sib dhos thiab qhov khoob ntawm qhov rooj thiab qhov rais yuav tsum tau ntim nrogpolyurethane ua npuas ncauj.
Siv daim kab xev tiv thaiv huab cua (xws li, butyl daim kab xev) rau sab nraud thiab npog nrog cov hlau battens kom ntseeg tau tias tag nrho airtightness.
Ib qho kev tsim kho phab ntsa yog "sab nrauv xim hlau ntawv + pob zeb wool txheej + sab hauv magnesium oxide board" sandwich vaj huam sib luag, sib txuas nrog cov txheej txheem nplaum thiab muab ob npaug rau nrog rivets los xyuas kom nruj kev sib txuas ntawm cov khaubncaws sab nraud povtseg.
4. Cov lus pom zoo rau thaj chaw huab cua sib txawv
Cov cheeb tsam txias heev (piv txwv li, Northern Europe, Canada): Pom zoo 100 mm tuab high-density pob zeb wool los yog polyurethane, ua ke nrog thermal so framing thiab muab ob npaug rau sealing.
Cov cheeb tsam kub thiab av noo (xws li, Southeast Asia, sab qab teb sab hnub tuaj United States): Pom zoo XPS lossis kaw-cell polyurethane, nrog rau qhov tseem ceeb ntawm cov dej noo thaiv thiab vapor retarder.
Cov cheeb tsam kub thiab qhuav (xws li Middle East, inland Australia): Pom zoo kom muaj kev cuam tshuam cov txheej txheem rwb thaiv tsev ua ke nrog cov pob zeb wool lossis airgel kom txo cov hnub ci tshav kub.
Chengdu Fangda Magic House's Rwb thaiv tsev xyaum
Chengdu Fangda Magic House muab kev sib txawv ntawm ntau yam ntaub ntawv - suav nrog pob zeb wool, polyurethane, XPS, thiab txawm tias airgel - raws li ib puag ncig kev nyab xeeb ntawm kev lag luam sib txawv. Lub tuam txhab tau xa cov kev daws teeb meem rwb thaiv tsev rau cov neeg siv khoom hauv ntau dua 30 lub teb chaws, kom ntseeg tau tias qhov kub thiab txias hauv tsev rau cov thawv tsev nyob hauv txhua qhov kev nyab xeeb.
