Insulated iav tau tsim los ntawm cov neeg Asmeskas hauv xyoo 1865. Nws yog cov khoom siv hauv tsev tshiab nrog cov rwb thaiv tsev zoo, lub suab rwb thaiv tsev, zoo nkauj zoo nkauj thiab siv tau, thiab tuaj yeem txo qhov hnyav ntawm lub tsev.
Nws yog lub suab nrov-insulating thiab kub-insulating iav ua los ntawm ob (los yog peb) daim iav, siv lub zog siab thiab high-airtight composite nplaum los khi cov iav rau ib qho txhuas alloy thav duab uas muaj cov desiccant. Insulated iav muaj ntau yam khoom zoo dua li cov iav ob chav glazed zoo tib yam, yog li nws tau raug lees paub los ntawm cov teb chaws thoob plaws ntiaj teb. Insulated iav yog kom qhov chaw sib npaug ntawm ob lossis ntau daim iav nrog kev txhawb nqa zoo thiab kev sib raug zoo thiab kaw lub periphery, kom cov roj qhuav tsim ntawm cov iav txheej. Space iav. Nws cov ntaub ntawv tseem ceeb yog iav, sov ntug spacers, kaum bolts, butyl roj hmab, polysulfide roj hmab, thiab desiccant.
Qauv
Insulated iav Insulated iav yog tsim los ntawm ob lossis ntau txheej ntawm cov iav ca. Siv lub zog siab thiab siab-air-tight composite nplaum nyob ib puag ncig rau kev sib raug zoo thiab muab ob lossis ntau daim iav nrog sealing strips thiab iav strips. Cov roj qhuav tau ntim rau hauv nruab nrab, thiab cov desiccant tau ntim rau hauv tus ncej kom ntseeg tau tias huab cua qhuav ntawm cov iav los xij. Ntau yam iav thawj cov nplooj ntawv nrog cov khoom sib txawv tuaj yeem xaiv tau raws li qhov yuav tsum tau ua, xws li tsis muaj xim tsis muaj pob tshab ntab iav, qauv iav, iav kub-absorbing, iav kub-reflecting iav, wired iav, tempered iav, thiab lwm yam thiab thav ntawv (aluminium thav duab lossis iav strips ) thiab lwm yam), ua los ntawm cementing, vuam lossis vuam.
Nws cov qauv yog raws li qhia nyob rau hauv lub cross-section ntawm ob-txheej insulating iav. Cov iav insulating tuaj yeem siv 3, 4, 5, 6, 8, 10, thiab 12mm tuab nplooj ntawv ntawm cov iav qub, thiab cov huab cua txheej tuab tuaj yeem siv 6, 9, thiab 12 hli ntu.
Lub thermal conductivity ntawm iav yog 27 npaug ntawm huab cua. Ntev npaum li lub iav insulating yog kaw, lub iav insulating muaj qhov zoo tshaj plaws thermal rwb thaiv tsev nyhuv.
Muaj ib qho chaw nruab nrab ntawm cov iav insulating iav. Lub thav duab tau ntim nrog cov desiccant kom ntseeg tau tias huab cua qhuav ntawm cov iav los xij. Qhov kev ncua deb ntawm ob txheej ntawm insulating iav yog feem ntau 8 hli.
High-performance insulating iav yog txawv los ntawm zoo tib yam insulating iav. Ntxiv nrog rau kev sib khi huab cua qhuav ntawm ob txheej iav, ib qho tshwj xeeb hlau zaj duab xis nrog zoo thermal kev ua tau zoo kuj coated rau ntawm huab cua txheej sab ntawm lub iav txheej. Nws tuaj yeem txiav tawm ntau lub zog los ntawm lub hnub mus rau chav tsev thiab muaj kev tiv thaiv hluav taws xob ntau dua.
Txoj Cai
Txij li thaum muaj ib qho desiccant hauv cov iav insulating uas tuaj yeem nqus dej molecules, cov roj tau qhuav. Thaum qhov kub thiab txias, condensation yuav tsis tshwm sim hauv cov iav insulating. Nyob rau tib lub sijhawm, cov dej lwg taw tes rau sab nrauv ntawm cov iav insulating tseem yuav nce. siab. Piv txwv li, thaum huab cua sab nraum zoov yog 5m / s, qhov kub hauv tsev yog 20 degree, thiab cov txheeb ze av noo yog 60%, 5 hli iav pib condense thaum lub sab nraum zoov kub yog 8 degree, thaum 16 hli (5+6+5) insulated iav yuav condense nyob rau hauv tib yam kev mob. Condensation tsuas yog tshwm sim thaum qhov kub ntawm sab nraum zoov yog -2 degree . Condensation tsuas yog pib thaum qhov kub ntawm sab nraum zoov ntawm 27mm (5+6+5+6+5) triple insulating iav yog -11 degree .
Muaj peb txoj hauv kev hloov hluav taws xob hauv cov iav insulating: hluav taws xob hloov pauv, hloov pauv convection thiab conduction hloov.
Kev hloov hluav taws xob
Kev hloov hluav taws xob hluav taws xob yog kev hloov hluav taws xob hauv daim ntawv ntawm hluav taws xob los ntawm cov hluav taws xob, uas suav nrog cov teeb pom kev zoo, infrared thiab ultraviolet hluav taws xob, ib yam li kev hloov ntawm hnub ci rays. Tsim nyog configuration ntawm insulating iav thiab tsim nyog thickness ntawm insulating iav spacers yuav txo tau cov kis ntawm lub zog los ntawm hluav taws xob, yog li txo lub zog poob.
Kev hloov pauv ntawm convection
Convection hloov yog vim qhov kub ntawm qhov sib txawv ntawm ob sab ntawm lub khob, ua rau huab cua poob rau sab txias thiab nce rau sab kub, ua rau huab cua convection thiab lub zog poob. Muaj ob peb lub laj thawj rau qhov tshwm sim no: ua ntej, kev sib khi ntawm cov iav thiab cov kab nrib pleb ib puag ncig yog qhov tsis zoo, ua rau cov roj hauv thiab sab nraum lub qhov rais thav duab ncaj qha sib pauv thiab tsim cov convection, ua rau lub zog poob; Qhov thib ob, qhov chaw sab hauv tsim qauv ntawm cov iav insulating tsis tsim nyog, ua rau cov roj hauv cov iav insulating los tsim cov convection vim qhov kub sib txawv, tsav lub zog pauv, yog li ua rau lub zog poob; Thib peb, qhov kub ntawm qhov sib txawv ntawm sab hauv thiab sab nraud ntawm lub qhov rais uas ua rau tag nrho lub cev yog qhov loj, ua rau qhov kub thiab txias sib txawv ntawm sab hauv thiab sab nraud ntawm cov iav insulating. Loj dua, cov huab cua ua ntej tsim cov convection ntawm ob sab ntawm cov iav insulating nrog kev pab los ntawm cov hluav taws xob txias thiab cov cua sov, thiab tom qab ntawd dhau los ntawm cov iav insulating tag nrho, ua rau lub zog poob. Tsim nyog insulating iav tsim yuav txo tau roj convection, yog li txo lub zog convection poob.
Kev hloov pauv
Kev hloov pauv kev hloov pauv yog los ntawm kev txav ntawm cov khoom ntawm cov khoom, tsav lub zog txav mus los, thiab ua tiav lub hom phiaj ntawm kev hloov pauv, ib yam li siv lub lauj kaub hlau ua noj lossis siv cov hlau soldering rau vuam khoom, thaum lub zog hloov pauv ntawm cov iav insulating. yog los ntawm cov iav thiab nws sab hauv. Ua tiav los ntawm huab cua. Peb paub tias cov iav thermal conductivity yog {{0}}.77W/mk. Lub thermal conductivity ntawm huab cua yog 0.028 W / mk. Nws tuaj yeem pom tias thermal conductivity ntawm iav yog 27 npaug ntawm huab cua, thiab muaj cov khoom siv hluav taws xob xws li dej molecules hauv huab cua cuam tshuam rau kev hloov pauv thiab kev hloov pauv kev ua haujlwm ntawm insulating iav zog. Qhov tseem ceeb tshaj plaws, yog li kev txhim kho kev sib khi ntawm cov iav insulating, yog qhov tseem ceeb hauv kev txhim kho thermal rwb thaiv tsev kev ua tau zoo ntawm insulating iav.
