Cua txias rwb thaiv tsevhuab cua, raws li lub npe implies, yog ib tug tshwj xeeb spare qhov chaw uas yog siv nyob rau hauv ua ke nrog zoo tib yam ntsug cua txias los yog dai cua txias.Ntawm qhov tod tes, cov kev xaiv ntawm cov khoom yuav tsum nruj me ntsis, thiab ib txheej ntxiv yog feem ntau ntim rau sab nrauv Composite zaj duab xis, yog li nws muaj peev xwm ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab rwb thaiv tsev kub.Thib ob, piv nrog cov kav dej yas zoo tib yam, qhov kev txuag cua sov nohuab cua tuaj yeem khoov tau dawb, yog li nws tuaj yeem hloov kho raws li qhov tseeb qauv thiab cheeb tsam., ces cia's kawm txog ntau yam ntawm cov cua txias rwb thaiv tsevhuab cuas los ntawm cov ntu nram qab no.
1. Yuav ua li cas xaiv cov cua txias rwb thaiv tsevhuab cua
Kev xaiv tsim nyog ntawm cov ntaub ntawv rwb thaiv tsev tsim nyog thiab kev tswj xyuas nruj ntawm kev tsim cov rwb thaiv tsev yog txoj hauv kev tseem ceeb kom txuag hluav taws xob hauv nruab nrab cua txias.Lub ntsiab kev ua tau zoo ntawm cov ntaub ntawv thermal rwb thaiv tsev yog raws li nram no: thermal conductivity, ntom, noo noo tsis kam, hluav taws tsis kam, installation kev ua tau zoo, thiab lwm yam.
1. Thermal conductivity
Thermal conductivity yog qhov yooj yim Performance index los ntsuas qhov zoo ntawm thermal rwb thaiv tsev cov ntaub ntawv, thiab txiav txim siab thermal rwb thaiv tsev kev ua tau zoo ntawm cov ntaub ntawv.Feem ntau, cov khoom siv qis dua 0.2W / (m·K) tuaj yeem siv ua cov khoom siv thermal rwb thaiv tsev.GB / T 17794 qhia meej tias: ntawm 40°C, thermal Lub thermal conductivity ntawm cov khoom siv rwb thaiv tsev tsis ntau tshaj 0.041W/(m·K);ntawm 0°C, thermal conductivity ntawm cov khoom siv rwb thaiv tsev tsis ntau tshaj 0.036W/(m·K);ntawm -20°C, thermal conductivity ntawm cov khoom siv rwb thaiv tsev tsis ntau tshaj 0.034W/(m·K).Nyob rau tib lub sij hawm, thermal conductivity kuj yog ib qho tseem ceeb parameter los txiav txim lub thickness ntawm rwb thaiv tsev txheej.Thaum lub rwb thaiv tsev thickness ntawm cov yeeb nkab tsis raug xaiv kom raug, cov dej condensation yuav raug tsim nyob rau sab nrauv ntawm cov txheej txheem rwb thaiv tsev, uas ua rau cov dej ntws tawm ntawm cov kav dej, dej seepage thiab pwm ntawm lub qab nthab, thiab lwm yam. cuam tshuam rau cov huab cua sab hauv tsev.
2. Humidity resistance factor
Qhov ntsuas dej tsis zoo yog qhov taw qhia tseem ceeb los ntsuas lub peev xwm ntawm cov ntaub ntawv thermal rwb thaiv tsev los tiv thaiv dej vapor nkag mus, thiab txiav txim siab lub neej kev pabcuam ntawm cov ntaub ntawv.GB / T 17794 qhia meej tias cov dej noo tsis kamμ ntawm cov ntaub ntawv thermal rwb thaiv tsev yuav tsum tsis pub tsawg tshaj 1500. Raws li lub xyoo ntawm kev siv ntau ntxiv, cov ntaub ntawv uas muaj ib tug me me noo noo tsis kam yog feem ntau yuav infiltrate dej vapor, uas ua rau ib tug ntse nce nyob rau hauv lub thermal conductivity ntawm cov ntaub ntawv rwb thaiv tsev, yog li ntawd. poob cov nyhuv rwb thaiv tsev.Yog li ntawd, qhib-cell rwb thaiv tsev cov ntaub ntawv xws li iav ntaub plaub yuav tsum tau pw nrog ib tug noo-pov thawj txheej kom ntev lub neej kev pab cuam ntawm cov khoom.
3. Kev ua haujlwm tua hluav taws
Txog rau tus qauv kev ua tau zoo hluav taws kub yog qhov yuav tsum tau ua kom zoo rau kev siv cov khoom siv rwb thaiv tsev, thiab kev tiv thaiv hluav taws ntawm cov khoom siv hluav taws xob yuav tsum ncav cuag cov nplaim hluav taws kub B1.Kev xaiv cov khoom siv rwb thaiv tsev thermal nrog kev ua haujlwm tsis zoo ntawm cov hluav taws kub yuav ua rau muaj kev nyab xeeb rau tag nrho cov cua txias hauv nruab nrab.Thaum hluav taws tshwm sim, hluav taws yuav kis tau sai heev thiab ua rau muaj kev puas tsuaj loj heev.
4. Kev teeb tsa kev ua haujlwm
Kev txhim kho kev ua tau zoo yog qhov tseem ceeb uas txiav txim siab kev tsim kho thiab kev tsim kho kom zoo.Kev xaiv tsis raug ntawm cov ntaub ntawv rwb thaiv tsev yuav cuam tshuam rau kev tsim kho thiab kev tsim kho kom zoo.Kev teeb tsa tsis raug kuj tseem tuaj yeem ua rau muaj qhov sib txawv hauv qhov system.Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov khoom siv rwb thaiv tsev uas tsim nyog thiab yooj yim rau nruab.
2. Yuav ua li cas xaiv qhov tuab ntawm cov khoom siv rwb thaiv tsev siv hauv cov kav dej cua txias?
Tus yuam sij rau kev soj ntsuam seb qhov zoo ntawm qhov project mus txog qhov tsim nyog (zoo heev) tus qauv nyob ntawm seb qhov zoo ntawm cov rwb thaiv tsev mus txog qhov tsim nyog (zoo heev) tus qauv.Qhov zoo ntawm cov rwb thaiv tsev nyob tsis yog tsuas yog nyob ntawm kev tsim kho theem ntawm rwb thaiv tsev, tab sis kuj nyob ntawm cov khoom siv rwb thaiv tsev xaiv.Cov tshuab hluav taws xob cua txias yuav tsum xaiv cov khoom thermal rwb thaiv tsev nrog cov thermal tsawg, ua tau zoo me me, ua tau zoo ntawm kev ua haujlwm.Cov kev xaiv tshwj xeeb yuav tsum raug txiav txim siab raws li qhov project qib thiab tus nqi, thiab qhov ua tau zoo thiab qhov zoo ntawm cov khoom yuav tsum tau them nyiaj rau.
Feem ntau, cov kav dej ntawmΦ20-32 : kuvmm yog 2.5 cm tuab.Cov kav dej ntawmΦ40-80 : kuvmm yog 3cm.Cov kav dej saum toj noΦ100mm yog 4cm.Cov kev cai tshwj xeeb yog xam los ntawm kev noj cov nqi qis tshaj plaws ntawm thermal rwb thaiv tsev thiab tiv thaiv condensation.Feem ntau, qhov rwb thaiv tsev ntawm cov kav dej txias hauv chav computer yog li 30-40mm, thiab nws yuav thicker sab nraum zoov, thiab ib puag ncig yuav nyias nyias yog tias muaj cua txias.
1. Lub thickness ntawm cov rwb thaiv tsev muaj feem xyuam rau cov khoom siv rau rwb thaiv tsev thiab qhov kub ntawm cov kua hauv cov kav dej yuav tsum tau insulated.
2. Tam sim no muaj ntau cov ntaub ntawv thermal rwb thaiv tsev, qee qhov zoo thiab kim, thiab cov qis qis kuj pheej yig, tab sis muaj ib lub hom phiaj: nws yog qhov zoo dua tsis txhob tsim cov hws ntawm cov khoom siv thermal rwb thaiv tsev.
