Kev xaiv cov vaj huam sib luag sandwich insulated zoo yog qhov kev txiav txim siab tseem ceeb hauv kev tsim kho chaw cia khoom txias. Cov khoom siv tseem ceeb ntawm cov vaj huam sib luag sandwich qhia txog kev siv hluav taws xob zoo, kev nyab xeeb hluav taws, thiab lub neej ntev ntawm cov qauv. Cov neeg ua haujlwm yuav tsum xaiv ntawm PU, PIR, thiab pob zeb wool raws li cov kev cai tshwj xeeb ntawm kev kub thiab kev nyab xeeb. Txhua hom vaj huam sib luag sandwich insulated muaj cov txiaj ntsig thiab cov teeb meem sib txawv rau kev tswj hwm chaw mus sij hawm ntev.
Kev Ua Haujlwm Thermal thiab Kev Txuag Hluav Taws Xob
Kev ua tau zoo ntawm cov cua sov, lossis R-tus nqi, txiav txim siab seb lub vaj huam sib luag tiv taus cua sov zoo npaum li cas. PU thiab PIR panels ua tus thawj coj hauv kev ua lag luam hauv kev ua haujlwm thermal. PU insulated sandwich panels feem ntau muab cov thermal conductivity ntawm kwv yees li 0.022 W / m·K. Qhov kev ua haujlwm siab no tso cai rau cov phab ntsa nyias dua thaum tswj hwm huab cua sab hauv ruaj khov. PIR yog kev hloov pauv ntawm PU thiab muab kev ruaj khov thermal zoo dua. Hauvkev cia khoom txias loj, hloov ntawm kev rwb thaiv tsev ib txwm mus rau qib siab PIR tuaj yeem txo qhov xav tau lub zog txias los ntawm 15% txog 20%. Qhov kev txo qis no txhais tau tias muaj ntau txhiab daus las hauv kev txuag txhua xyoo rau lub tsev rau khoom nruab nrab.
Cov vaj huam sib luag pob zeb wool muaj cov thermal conductivity siab dua, feem ntau nyob ib puag ncig 0.035 txog 0.040 W / m · K. Yuav kom ua tiav cov nyhuv rwb thaiv tsev zoo ib yam li 100 hli PIR vaj huam sib luag, koj yuav xav tau lub vaj huam sib luag pob zeb wool yuav luag 180 hli tuab. Qhov tuab ntxiv no txo qhov ntim cia sab hauv ntawm koj lub chaw. Cov ntaub ntawv qhia tau tias kev siv PIR hla cov pob zeb wool tuaj yeem ua rau qhov chaw pallet siv tau ntau dua 5% txog 8% hauv tib lub tsev. Rau cov lag luam uas muab qhov tseem ceeb rau cov nqi hluav taws xob tsawg thiab qhov ceev cia siab tshaj plaws, PU thiab PIR tseem yog cov kev xaiv tseem ceeb. Lawv txo qhov kev ua haujlwm ntawm cov compressors thiab txuas ntxiv lub neej ntawm tag nrho lub tshuab tub yees.
Kev Nyab Xeeb Hluav Taws thiab Kev Pov Hwm
Kev tiv thaiv hluav taws yog qhov uas cov pob zeb wool zoo tshaj li cov ua npuas ncauj ua los ntawm cov khoom siv. Cov pob zeb wool yog cov khoom siv uas tsis kub hnyiab nrog lub ntsiab lus yaj tshaj 1,000 ° C. Nws feem ntau ua tiav qhov ntsuas hluav taws A1, muab qib siab tshaj plaws ntawm kev tiv thaiv rau cov chaw muaj kev pheej hmoo siab. Qhov sib piv, PIR vaj huam sib luag yog "fire-retardant." Lawv hlawv thaum raug hluav taws, tsim ib txheej tiv thaiv uas qeeb qeeb hluav taws kis. PIR feem ntau ua tau raws li cov qauv B-s1, d0 raws li European kev faib tawm. ThaumPU vaj huam sib luagyog ib txwm muaj, lawv tsis tshua muaj kev tiv thaiv hluav taws thiab tej zaum yuav ua rau muaj pa luam yeeb ntau dua thaum muaj hluav taws kub.
Cov tuam txhab pov hwm feem ntau nyiam siv cov pob zeb wool thiab FM-pom zoo PIR panels. Cov chaw siv cov qauv PU panels feem ntau ntsib cov nqi pov hwm siab dua 20% txog 30% dua li cov uas siv cov pob zeb wool. Hauv qee thaj chaw, cov tuam txhab pov hwm yuav tsis kam them cov khoom siv txias uas tsis muaj cov cores tiv taus hluav taws tau ntawv pov thawj. Ib qho xwm txheej hluav taws kub hauv ib qho chaw uas muaj PU-insulated tuaj yeem ua rau lub tsev puas tsuaj tag nrho hauv ob peb feeb. Cov pob zeb wool panels muab kev tiv thaiv hluav taws kub tseem ceeb, feem ntau muab 60 txog 120 feeb ntawm kev tiv thaiv hluav taws kub. Kev tiv thaiv no cawm txoj sia thiab tiv thaiv kev poob tag nrho ntawm cov khoom muag kim thiab cov khoom siv hauv tsev thaum muaj xwm txheej ceev.
Kev Ncaj Ncees ntawm Cov Qauv thiab Kev Tiv Thaiv Dej
Cov chaw cia khoom txias ntsib qhov sib txawv ntawm qhov kub thiab txias uas ua rau muaj kev ntxhov siab rau lub cev. PU thiab PIR panels muaj cov qauv zoo heev thiab muaj zog rau qhov hnyav. Lawv cov qauv kaw-cell, uas feem ntau tshaj 90%, tiv thaiv cov pa dej kom tsis txhob nkag mus rau hauv lub plawv. Cov dej noo yog tus yeeb ncuab ntawm kev rwb thaiv tsev; qhov nce 1% ntawm cov dej noo tuaj yeem txo cov nqi rwb thaiv tsev los ntawm 25%. Vim tias PIR thiab PU tiv taus dej, lawv tswj lawv tus nqi R rau ntau xyoo caum. Lawv kuj tseem tiv taus cov khoom hnyav ntawm cov evaporators dai ntawm qab nthab thiab cov khoom siv txias tau zoo.
Cov vaj huam sib luag pob zeb wool yog ua los ntawm cov fibers mineral, uas yog qhib-cell ntuj. Txawm hais tias cov chaw tsim khoom ntxiv cov khoom siv tiv thaiv dej, cov pob zeb wool tseem tuaj yeem nqus cov dej noo yog tias daim tawv nqaij hlau raug tho. Cov pob zeb wool ntub poob nws cov khoom rwb thaiv tsev yuav luag tag nrho thiab ua rau hnyav heev. Qhov hnyav nce no tuaj yeem hem kev nyab xeeb ntawm cov qauv ntawm lub ru tsev. Txawm li cas los xij, cov pob zeb wool muaj cov suab rwb thaiv tsev zoo dua, txo cov suab nrov hauv chav cog ntoo txog li 30 decibels. Qhov no yog qhov txiaj ntsig zoo rau cov chaw nyob ze ntawm thaj chaw nyob. Cov neeg ua haujlwm yuav tsum xyuas kom meej tias cov pob zeb wool sib koom ua ke zoo meej kom tiv thaiv "qhov cuam tshuam chimney" ntawm cov dej noo tsiv teb tsaws chaw.
Cov Nqi Siv Tau Hauv Lub Neej Thiab Kev Cuam Tshuam Rau Ib Puag Ncig
Tus nqi mus sij hawm ntev ntawm ib lub vaj huam sib luag suav nrog tus nqi yuav khoom, kev saib xyuas, thiab kev pov tseg thaum kawg. Cov vaj huam sib luag PU feem ntau muaj tus nqi pib qis tshaj plaws, ua rau lawv nrov rau cov haujlwm uas xav txog nyiaj txiag. Txawm li cas los xij, cov vaj huam sib luag PIR muab qhov rov qab zoo dua ntawm kev nqis peev vim lawv qhov kev sib xyaw ua ke ntawm kev ua haujlwm zoo thiab cov nqi pov hwm qis dua. Tshaj li 15 xyoo, kev txuag hluav taws xob los ntawm PIR feem ntau them rau qhov sib txawv ntawm tus nqi pib peb zaug dhau. Cov pob zeb wool muaj tus nqi teeb tsa siab dua vim nws qhov hnyav, feem ntau xav tau cov hlau khov kho dua thiab cov khoom siv tsa tshwj xeeb.
Kev ruaj khov tab tom dhau los ua ib qho tseem ceeb hauv xyoo 2026. Cov pob zeb wool yog cov khoom siv rov ua dua tshiab tau zoo heev thiab ua los ntawm cov pob zeb volcanic ntau heev. PU thiab PIR ua npuas ncauj nyuaj rau rov ua dua tshiab, txawm hais tias cov qauv "bio-polyol" tshiab dua nkag mus rau hauv kev ua lag luam. Thaum xam cov pa roj carbon, cov pob zeb wool tau qhab nia zoo ntawm kev pov tseg thaum kawg ntawm lub neej. Ntawm qhov tod tes, PIR tau qhab nia zoo dua ntawm cov pa roj carbon ua haujlwm vim nws txuag hluav taws xob ntau dua thaum lub sijhawm lub tsev lub neej. Kev xaiv lub vaj huam sib luag nrog cov ntsiab lus rov ua dua tshiab siab tuaj yeem pab lub chaw ua tiav daim ntawv pov thawj LEED lossis BREEAM. Feem ntau cov vaj huam sib luag PIR zoo tshaj plaws tam sim no muaj lub neej ntev li 25 txog 30 xyoo yam tsis muaj kev puas tsuaj loj.
Kev xaiv ntawm PU, PIR, thiab pob zeb wool yuav tsum tau sib npaug cov kev xav tau thermal tawm tsam kev pheej hmoo hluav taws. PIR panels tam sim no muab cov kev daws teeb meem ntau yam rau kev khaws cia txias niaj hnub vim lawv cov R-nqi siab thiab cov khoom tiv taus hluav taws. Pob zeb wool tseem yog tus qauv kub rau thaj chaw muaj kev pheej hmoo siab uas kev nyab xeeb hluav taws yog qhov tseem ceeb tshaj plaws. PU yog qhov kev xaiv ua haujlwm rau cov ntawv thov me me, tsis muaj kev pheej hmoo nrog cov peev nyiaj nruj.
