Ntau yam nyob ntawm qhov raug suav ntawm cov rwb thaiv tsev thermal: ob qho tib si kev nplij siab ntawm lub tsev thiab cov nqi cua sov. Yog li ntawd, nws yuav tsis ua yam tsis muaj lub rhaub. Ntxiv mus, koj yuav tsum tau nrog xws li ib lo lus nug xws li xam lub thickness ntawm rwb thaiv tsev rau phab ntsa - dab tsi yuav tsum tau. Cov ntaub ntawv twg yog qhov zoo tshaj plaws rau cov xwm txheej ntawm koj cheeb tsam ntawm qhov chaw nyob, thiab qhov twg zoo dua: polystyrene ua npuas ncauj, ua npuas ncauj yas, ntxhia ntaub plaub, ecowool, plaster lossis lwm yam khoom tiav.
Yuav ua li cas nrog kev suav cov rwb thaiv koj tus kheej
Nyob rau hauv cov ntaub ntawv no, tus nqi ntawm qhov tsawg kawg nkaus thermal kuj tsis yog tus nqi kawg. Nws tus nqi ncaj qha nyob ntawm qhov chaw huab cua ntawm thaj av. Thaum xam qhov ntsuas no, lub sijhawm ntawm lub caij cua sov, nrog rau qhov sib txawv ntawm qhov kub thiab txias sab hauv tsev, raug coj mus rau hauv tus account. Nrog rau qhov no nyob rau hauv lub siab, thov nco ntsoov tias cov coefficient ntawm tshav kub hloov tsis kam rau sab nrauv phab ntsa ntawm lub tsev nyob yuav tsum yog.yuav tsum tsawg kawg yog 3.28 rau Moscow, 1.79 rau Sochi thiab 5.28 rau Yakutsk.
thermal tsis kam ntawm phab ntsa yog sib npaug rau qhov sib npaug ntawm qhov tsis kam ntawm txhua txheej ntawm cov qauv, tsis hais seb lawv puas yog load-bearing lossis insulating. Nws ua raws los ntawm qhov no tias lub thickness ntawm thermal rwb thaiv tsev nyob ntawm seb hom khoom siv thaum siv. Yog li ntawd, lub tsev cib thiab pob zeb yuav tsum muaj kev rwb thaiv tsev ntau dua piv rau cov ntoo thiab ua npuas ncauj.
Ua tib zoo mloog rau cov tuab ntawm cov khoom siv hauv tsev xaiv rau kev tsim kho ntawm cov qauv, nrog rau nws cov thermal conductivity. Qhov me dua qhov tuab ntawm kev txhawb nqa, qhov ntau dua qhov tuab ntawm cov rwb thaiv tsev yuav tsum yog.
Yog tias nws yuav tsum tau siv rwb thaiv tsev rau phab ntsa nrog lub thickness ntau dua li niaj zaus, nws raug nquahu kom nqa cov rwb thaiv tsev sab nraud. Txoj hauv kev no yuav pab tswj cov cai ntawm ergonomics thiab txuag qhov chaw sab hauv ntawm lub tsev. Lwm qhov zoo dua ntawm kev rwb thaiv tsev sab nraum zoov yog kev tiv thaiv kev ya raws hauv chav.
Dab tsi yog thermal conductivity
Thermal conductivity yog cov cuab yeej ntawm cov khoom siv los xa cov cua sov. Ntoo, cib, qhob, ua npuas ncauj blocks muaj qhov sib txawv thermal conductivity, thiab nce cua av noo, thiab lwm yam, pab txhawb rau nws nce. Thermal conductivity kuj muaj tus nqi rov qab, uas yog hu ua thermal resistance. Txhawm rau txiav txim siab tus lej no, siv cov thermal conductivity qhuav qhia hauv phau ntawv hla tebchaws rau cov khoom siv. Yog tias tsis muaj, koj tuaj yeem siv lub rooj tshwj xeeb.
Ua tib zoo saib xyuas qhov tseeb tias nyob rau hauv cov ces kaum, junctions ntawm load-bearing lug thiab lwm yam tshwj xeeb cov qauv, thermal conductivity yog siab tshaj nyob rau saum npoo ntawm ib tug ca phab ntsa. Nws yog nyob rau hauv xws li qhov chaw uas thiaj li hu ua txias choj tshwm sim, vim hais tias cov cua sov khiav. Koj tuaj yeem paub qhov tshwm sim no los ntawm smudges ntawm phab ntsa los ntawm sab hauv lub tsev. Txhawm rau tiv thaiv qhov tshwm sim no, cov kws tshaj lij pom zoo kom nce cov thermal tiv thaiv mus rau ¼ ntawm qhov tsawg kawg nkaus tso cai.
Xaiv ntawm thermal conductivity ntawm lub tsev siv piv txwv
txhawm rau tiv nrog txoj haujlwm no thiab txiav txim siab cov thermal conductivity, lub laij lej zoo tib yam yuav los ua ke. Ua ntej, nws yog ib qho tsim nyog yuav tsum tau ua raws li cov cua kub hloov mus rau cov txheej txheem load-bearing. Ua li no, lub thickness ntawm cov qauv yog muab faib los ntawm thermal conductivity ntawm phab ntsa rwb thaiv tsev siv nyob rau hauv cov ntaub ntawv no. Piv txwv li, cov pob zeb ua npuas ncauj nrog qhov ntom ntom ntawm 300 yog tus cwj pwm los ntawm thermal conductivity Performance index ntawm 0.29. Nws hloov tawm hais tias nrog ib tug thaiv thickness ntawm 30 cm, lub thermal kuj yog:
0, 3 / 0, 29=1, 03
Cia li mus rho tawm tus nqi xam los ntawm qhov tsawg kawg nkaus tso cai. Yog li, rau cheeb tsam Moscow thiab Moscow, thermal conductivity ntawm phab ntsa rwb thaiv tsev yuav tsum tsis pub tsawg tshaj 2.25 (3.28 - 1.03=2.25).
Cov kauj ruam tom ntej yog muab cov thermal conductivity ntawm cov rwb thaiv tsev los ntawm qhov yuav tsum tau thermal resistance, uas ua rau muaj tus lej qhia txog cov thickness ntawm cov txheej yuav tsum tau. Piv txwv li, thermal conductivitymineral wool - 0.045, uas txhais tau hais tias nws thickness yuav tsum yog tsawg kawg yog 0.1 m (0.0452.25=0.1).
Yam yuav tsum nco ntsoov thaum xam cov thermal conductivity
Ntawm lwm yam, koj yuav tsum tau txiav txim siab qhov chaw ntawm lub lwg taw tes thiab tsis txhob hnov qab txog qhov ntsuas no thaum txiav txim siab lub thickness ntawm rwb thaiv tsev rau sab nrauv phab ntsa.
Lub pas dej lwg yog qhov chaw nyob hauv phab ntsa uas qhov kub thiab txias poob mus rau theem uas cov ntaub ntawv condensation - dew. Thaum qhov chaw no nyob rau sab hauv ntawm chav tsev, qhov no ua rau fogging, vim tias cov txheej txheem putrefactive pib. Xav txog qhov ntsuas no thaum xam cov thickness ntawm rwb thaiv tsev rau phab ntsa.
Nco ntsoov tias qhov txias dua yog sab nraud, qhov ze dua qhov dej lwg ze rau sab hauv. Qhov kub thiab av noo ntau dua hauv chav, qhov dew point hloov siab dua.
Dab tsi yog qhov tuab ntawm rwb thaiv tsev rau cov phab ntsa
Ntau cov ntaub plaub, lossis ecowool, qhov zoo tshaj plaws ntawm nws hom rau insulating phab ntsa ntawm lub tsev ncej.
Qhov xav tau tuab yog txiav txim siab siv tib cov qauv uas tau tham saum toj no. Yog tias tsim nyog los npaj ib txheej ntxiv rau phab ntsa multilayer, ntxiv 10% rau nws tus nqi. Qhov no yog vim lub thickness ntawm cov phab ntsa rau lub tsev, cov rwb thaiv tsev uas koj xaiv, yog tsawg dua nrog ib txwm siv technology, thiab qhov no qhia tau hais tias muaj peev xwm hloov lub lwg point ze rau lub puab nto. Tias yog vim li cas cov kws tshaj lij pom zoo kom tsis txhob txuag lub thickness ntawm rwb thaiv tsev.
Yuav ua li cas xam lub thickness ntawm npuas
Polyfoam yog cov khoom nrov uas nyiam cov xim vim nws cov thermal conductivity tsawg, lub teeb yuag thiab noo noo tsis kam, thiab qhov tseem ceeb tshaj, nws pheej yig. Cov khoom siv no tsis txhob cia cov pa tawm, yog li ua tib zoo saib xyuas qhov no thiab nco ntsoov tias cov khoom siv no tsis haum rau kev rwb thaiv tsev sab hauv.
zoo dua, ua npuas ncauj yog muab tso rau sab nraud lossis sab hauv phab ntsa. Lub thermal conductivity, zoo li nyob rau hauv cov ntaub ntawv ntawm lwm yam ntaub ntawv, nyob ntawm seb qhov ceev ntawm lub npuas. Piv txwv li, nrog ib tug ceev ntawm 20 kg / m3, lub thermal conductivity yog 0.035. Yog li ntawd, ua npuas ncauj nrog ib tug thickness ntawm 0.05 cm yuav txaus los muab kev pom zoo thermal kuj nyob rau theem ntawm 1.5 m.
Txoj kev suav cov thickness ntawm rwb thaiv tsev rau lub ru tsev thiab qab nthab
Tsis muaj dab tsi tshiab nrog cov qauv rau kev suav - lawv txhua tus tib yam. Tab sis nrog qhov tsawg kawg nkaus thermal kuj, txhua yam txawv me ntsis. Unheated attic chaw, raws li txoj cai, yog insulated nrog tej rwb thaiv tsev. Nyob rau hauv cov ntaub ntawv no, tsis muaj kev txwv thickness yog muab tso rau pem hauv ntej, yog li ntawd nws yog pom zoo kom nce lawv mus txog rau ib tug thiab ib nrab sij hawm nyob rau hauv kev sib piv rau cov suav sawv daws yuav.
Yog tias peb tab tom tham txog chav tsev so, ces qhov no nws yuav tsim nyog siv cov ntaub ntawv uas tsis muaj thermal conductivity.
Tam sim no, paub txog qhov tuab ntawm phab ntsa rwb thaiv tsev yuav zoo rau ib lossis lwm qhovcov khoom siv hauv tsev, nrog rau kev coj ua los ntawm cov piv txwv tau muab thiab siv cov qauv, kev suav cov ntsuas ntsuas yuav ua tau yam tsis muaj teeb meem, qhov no yuav tsis yog ib txoj haujlwm nyuaj.
