Yuav ua li cas los xaiv tus txoj cai rwb thaiv tsev. Rooj ntawm thermal conductivity ntawm lub tsev ntaub ntawv

Txoj kev nyab xeeb nyob rau hauv ntau qhov chaw ntawm peb lub teb chaws yog heev heev. Thiab vim hais tias yuav luag txhua txhua lub tsev ua nyob rau hauv lub teb chaws nyob rau hauv kev xav tau ntawm rwb thaiv tsev. ib tug ntau yam ntawm cov ntaub ntawv yuav siv tau rau xws li ib tug txheej txheem. Nyob rau hauv lub xaiv ntawm lub insulator nyob rau hauv thawj tag nrho cov xyuam xim rau cov neeg kawm ntawv ntawm nws thermal conductivity. Lub sab nws yog, qhov ntau zoo lub sheathing. Yuav kom txiav txim no daim duab muaj ib tug tshwj xeeb cov lus ntawm thermal conductivity ntawm lub tsev cov ntaub ntawv.

ua npuas ncauj insulators

Qhov no pab pawg neeg ntawm cov ntaub ntawv nyob rau hauv cov nqe lus ntawm tshav kub preservation yog xav tau qhov zoo tshaj plaws. Yuav kom nws nyob rau hauv thawj qhov chaw muaj xws li insulators li polystyrene thiab ua npuas ncauj. SNIP lub tsev ntaub ntawv thermal conductivity rooj kom meej meej qha tau lawv cov hauj lwm zoo.

Xa mus rau lub merits ntawm cov insulators ntawm cov pab pawg neeg thiab hais tias lawv yuav tsis ntshai dej. Tab sis lub ntsiab disadvantage ntawm tag nrho cov foams yog xam hais tias lawv yog kiag li tsis muaj peev xwm kis tau los ntawm nws tus kheej ya raws pa. Lub dai kom zoo nkauj lawv cov tsev, ib tug thiaj li hu ua cov nyhuv ntawm ib tug thermos. Thiab li no, tus tswv tau coj kev soj ntsuam ntxiv los txhim kho lub sab hauv tsev kev nyab xeeb - nruab huab cua txias thiab cua system. Tsis tas li ntawd disadvantage ntawm cov ntaub ntawv yog xav tau qhov tseeb hais tias lawv suab tsis txhob ncua nrov. Nyob rau hauv tas li ntawd, ua npuas ncauj insulators yog heev fond ntawm gnawing nas thiab nas, ua nyob rau hauv cov nqe vaj lug kub. Thiab qhov no, ntawm chav kawm, muaj txhawb rau koj ua txhaum ntawm lub sam xeeb sov txheej thiab txo nws cov hauj lwm zoo.

mineral wool

Qhov thib ob nrov tshaj plaws ntau yam ntawm insulators. Thaum tshav kub kub nyob rau hauv lub chav tsev, nws yuav ib tug me ntsis zuj zus tshaj ua npuas ncauj ntaub ntawv. Qhov no pab pawg neeg no muaj xws li feem ntau basalt thiab iav ntaub plaub. Lub ntsiab zoo ntawm no hom ntawm cua sov yog pom tau hais tias yuav tsis muaj nqi, raws li zoo raws li chav thiab zoo suab rwb thaiv tsev zog. Qhov tsis zoo ntawm mineral wool muaj xws li nws muaj peev xwm mus nqus dej. Tsis tas li ntawd disadvantage ntawm cov ntaub ntawv yog xav tau qhov tseeb hais tias lawv emit teeb meem vapors ntawm phenol-formaldehyde resins.

Yuav ua li cas muab los xav thaum xaiv ib tug

Thaum muas ib insulator nyob rau hauv thawj qhov chaw yuav tsum xyuam xim rau tej parameter raws li nws cov thickness. Tsis tas li ntawd rau lub zoo rwb thaiv tsev nws yog ib qho tseem ceeb heev ntsuas xws li cov thermal conductivity ntawm lub tsev cov ntaub ntawv. Rooj nrog qhov tseem ceeb xam qhovkev nyob rau hauv ntau hom insulators, yuav hais hauv qab no.

Cov kev kawm thickness ntawm cov khoom nyob rau hauv ob peb yam tseem ceeb:

• nws degree ntawm thermal conductivity;

• kev nyab xeeb cheeb tsam;

• cov neeg kawm ntawv ntawm thermal conductivity ntawm cov ntaub ntawv uas muab lug;

• phab ntsa thickness.

Rau tsev nyob rau hauv central Russia raws li cov qauv nteg npaj insulated txheej ntawm xws thickness uas nws muaj peev xwm mus khaws thaum tshav kub kub yog tib yam li hais tias ntawm lub brickwork 1.5 meters.

Rau ntoo vaj tse, qhov no daim duab yuav ua tau me me thiab. Lub fact tias cov tuav thiab beam lawv tus kheej zoo heev khaws thaum tshav kub kub.

Rooj ntawm thermal conductivity ntawm lub tsev ntaub ntawv

Yog li ntawd, yog dab tsi zoo nyob rau hauv no hais txog yog sib txawv los yog hais tias ib tug insulator? Yuav ua li cas zoo niaj hnub tsev ntaub ntawv ntawm no ntau yam khaws thaum tshav kub kub, yuav muaj nyob rau hauv lub rooj.

Rooj thermal conductivity ntawm lub tsev ntaub ntawv, yog li uas qhia tias qhov zoo tshaj rwb thaiv tsev thaum lub caij yog polystyrene. Ntaub plaub tsiaj, raws li twb tau hais, yog tau ncua tus mob khaub thuas me ntsis zuj zus.

Yuav ua li cas mus xaiv cov ntaub ntawv uas

Yog li, ib tug heev ib qho tseem ceeb qhia ntawm cov hauj lwm zoo ntawm cov rwb thaiv tsev ntawm lub tsev lub hnab ntawv yog lub thermal conductivity ntawm lub tsev cov ntaub ntawv. Lub rooj, ntawm chav kawm - yog tsis tus tsuas yog txoj kev uas yuav tau paub nws tus xov tooj. Lub degree ntawm thermal conductivity ntawm lub insulator yog feem ntau qhia rau nws los ntawm lub chaw tsim tshuaj paus. Cov nram qab no qhov tseem ceeb tej zaum yuav tau cim rau ntawm daim ntawv lo:

• degree ntawm thermal conductivity nyob rau hauv ib tug qhuav ib ncig ntawm ib tug kub ntawm 10 ^{° C;}

• nyob rau hauv ib tug qhuav qhov chaw nyob rau ²⁵ ° C;

• nyob rau hauv txawv av noo tej yam kev mob (A los yog B).

Thiab foams thiab wool feem ntau nyob rau hauv ib tug tuab ntawm 10 los yog 5 cm. Raws li ib tug sib piv cov lus uas qhia cov thermal conductivity ntawm lub tsev ntaub ntawv, rau central Russia txheej insulated pob zeb vaj tse yuav tsum tsis txhob yuav tsawg tshaj li 12-13 cm. Txawm li cas los, nyob rau hauv kev xyaum, feem ntau yog txaus thiab 10 cm. Yog li ntawd rwb thaiv tsev suburban khiav lag luam vaj tse los yog ib txheej ntawm cov ntaub ntawv uas 10 cm, los yog nyob rau hauv lub ob insulator 5 cm tuab. Cov yav tas txoj kev yog siv feem ntau. Nrog rau qhov no technology, lub thib ob txheej yog pw li hais tias cov thawj cov pob qij txha tau kiag li lawm. Cov no tshaj plaws sealing ib tug sov hauv ob sab phlu.

Ntaub ntawv npaj rau cov kev rho tawm ntawm lub teb chaws lub tsev, nyob rau hauv peb lub sij hawm, raws li koj tau pom, muaj ntau ntau yam. Yog hais tias qhov kev kawm, rwb thaiv tsev yuav tau xaiv raws li variant ua npuas ncauj thiab mineral wool. Nyhuv raws li lub rooj qhia tau hais tias lub thermal conductivity ntawm lub tsev ntaub ntawv, thiab nyob rau hauv uas thiab nyob rau hauv lwm yam ntaub ntawv nws yuav yuav cia li zoo. Ntawm cov hoob kawm, li cas los xij, tsuas yog thaum lub hauv ob sab phlu walling yuav txaus tuab.
