Architects lub davhlau ntawm kev zoo nkauj feem ntau raug txwv los ntawm kev siv thev naus laus zis nruj. Openwork thiab huab cua yees ua los ntawm iav thiab hlau tsis yog ib txwm muaj peev xwm tsim tau hauv peb cov kev nyab xeeb vim tias nws yuav tsum tau siv cov qauv uas tuaj yeem khaws cov cua sov hauv lub tsev. Classical iav tsis haum rau lub hom phiaj no.
Low-emissivity iav tau tsim los ua kom tau raws li qhov xav tau ntawm lub ntiaj teb no lub zog txuag hluav taws xob. Kev taw qhia ntawm cov khoom siv no tso cai rau koj siv tag nrho nws qhov zoo nkauj thiab kev lag luam zoo.
Txoj Cai Ua Haujlwm
Lub tswv yim ntawm "emission" txhais tau tias muaj peev xwm los cuam tshuam cov hluav taws xob thermal. Nrog qis emissivity qhov tseem ceeb, chav tsev yuav poob qis dua. Qhov ntsuas no - qhov emitter nto (E) rau cov tsom iav txuag hluav taws xob yog 4 npaug tsawg dua rau cov khoom qub. Txhawm rau tsim kom muaj qhov kub thiab txias, ib txheej ntawm cov hlau oxides yog siv rau iav. Electrons hauvCov zaj duab xis nyias no tau ntim nruj heev uas qhov ntev wavelengths ntawm infrared tawg yooj yim tsis tuaj yeem hla, thiab feem ntau rov qab.
Vim li ntawd, cov iav uas tsis tshua muaj hluav taws xob xa tawm luv luv ultraviolet hnub ci hluav taws xob, thiab cov cua sov hauv chav tau sau. Sab nraud infrared nthwv dej ntawm cov hluav taws xob hluav taws xob tsis tau tawm lawm, cuam tshuam los ntawm qhov chaw.
K-iav
Low-emissivity iav muaj ob hom. Cov khoom siv tawv coated - K-iav. Nto plating yog nqa tawm thaum lub iav nyob rau hauv lub kub kub. Raws li qhov tshwm sim ntawm cov tshuaj tiv thaiv, hlau oxide molecules nkag mus rau hauv cov qauv ntawm iav nws tus kheej. Qhov tshwm sim yog cov khoom siv coated uas ua tau zoo tiv thaiv kev puas tsuaj thiab hnav. Nws tuaj yeem ua tiav zoo li iav zoo tib yam thiab khaws cia ntev npaum li koj nyiam.
Qhov tsis zoo yog nws tus nqi siab, yog li iav siv rau hauv cov chaw uas yuav tsum tau ua haujlwm nruj heev - hauv tsev cog khoom, chaw khaws cia, lub vaj lub caij ntuj no.
i-iav
Hom ntau dua yog mos coated i-iav. Silver oxides yog txau rau ntawm qhov chaw siv cov khoom siv nqus tsev siab. I-iav yog pheej yig dua li nws cov thawj coj thiab khaws cov cua sov ib thiab ib nrab zaus zoo dua. Txawm li cas los xij, cov khoom siv no muaj ntau qhov tsis zoo. Qhov qis-emissivity iav txheej yog rhiab rau kev puas tsuaj, yog li qhov saum npoo yog khawb tau yooj yim. Hlau oxides nquag hnov mob nrog oxygen, yog li lub txee lub neej nyob rau hauv qhib cuazoo nkauj txwv. Qhov teeb meem no daws tau los ntawm qhov tseeb tias nws yog siv nyob rau hauv ob chav glazed qhov rais nrog ib tug polarized nto sab hauv los yog siv nyob rau hauv ib tug multilayer iav txheej.
YGlazed windows
Insulating glazing nrog tsawg-emission iav yuav pab kom txo tau cov nqi cua sov. Kev suav tau pom tias nyob rau hauv txoj kev no nws muaj peev xwm txuag tau txog 700 litres ntawm cov roj sib npaug hauv ib xyoos.
Hauv qhov no, koj tuaj yeem hloov lub tswv yim ntawm qhov chaw cua sov. Nyob rau saum npoo ntawm lub qhov rais nrog iav zoo tib yam, qhov kub tsis siab tshaj +5 degrees ntawm qhov kub ntawm sab nraud ntawm -20 degrees. Lub qhov rais nrog cov iav qis qis pab kom ua tiav qhov ntsuas ntawm +14 degrees. Ntawd yog, nws tuaj yeem rov faib cov khoom siv hluav taws xob, vim tias cov qauv yuav tsis yog qhov chaw txias txias. Tam sim no koj tuaj yeem siv sijhawm nyob ntawm lub qhov rais yam tsis muaj kev ntshai ntawm khov. Qhov kev pheej hmoo ntawm condensation kuj ploj mus, vim tias ya raws tsuas yog ua rau ntawm qhov chaw txias hauv chav sov.
Qhov rai ib chav tsev ob chav glazed qhov rais nrog cov iav uas tsis tshua muaj hluav taws xob muaj txiaj ntsig zoo dua li ob chav glazed qhov rais los ntawm classic ib qho. Qhov no ua rau nws yooj yim rau kev tsim thiab txo cov nqi cua sov. Kev suav qhia tias tus nqi qis-e iav them tawm los ntawm kev txuag hluav taws xob hauv 1.5-2 xyoos.
Nyiaj-txuag technologies yog nyob rau hauv pem hauv ntej hnub no. Hauv Tebchaws Europe, cov iav qis-emission tau pib ua haujlwm. Nyob rau hauv Russia, qhov no tseem yog ib tug tshiab tiam sis. Kev siv xws li ib qho tshiab yuav ua rau nws muaj peev xwm ua tau raws li qhov tseeb architectural kev taw qhia - pob tshabfacades. Tib lub sijhawm, cov dej num ua tau zoo kuj raug daws - txuag roj ntawm cua sov.
Yog li, maj mam noj hauv paus hauv ob chav glazed, iav qis tau dhau los ua cov khoom siv paub.
