Dab tsi yog qhov tseem ceeb ntawm lub zog txuag lub qhov rooj thiab qhov rais? Nws yog 4 cov ntsiab lus!
Peb lub teb chaws yog cov neeg siv hluav taws xob loj. Txhawm rau txo qis kev siv hluav taws xob, lub teb chaws tau ua ntau yam kev hloov kho hluav taws xob txuag. Ntawm tag nrho cov kev siv hluav taws xob ntawm lub tsev hnab ntawv, kev siv lub zog ntawm lub tsev qhov rooj thiab qhov rais suav txog 49% ntawm nws lub zog siv.
Lub tsev qhov rooj thiab qhov rais yog qhov tsis muaj zog tshaj insulating khoom ntawm lub tsev. Nrog rau kev txhim kho txuas ntxiv ntawm tib neeg cov qauv kev ua neej nyob, txhawm rau tsim kom muaj qhov chaw nyob zoo, kev siv cua txias hauv tsev lossis cua sov tau dhau los ua ntau dua. Qhov rooj thiab qhov rais yog ib qho ntawm cov ntaub thaiv npog ntawm cov tsev. , ncaj qha cuam tshuam rau lub zog txuag kev ua haujlwm ntawm lub tsev. Kev txhim kho cov rwb thaiv tsev kev ua tau zoo ntawm cov qhov rooj thiab qhov rais yog txoj hauv kev tseem ceeb los xyuas kom meej lub zog siv ntawm lub tsev. Niaj hnub no, kev siv lub zog txuag lub qhov rooj thiab qhov rais rau lub tsev txuag hluav taws xob tau nyiam ntau thiab ntau dua.
Vim tias kuv tsis muaj kev nkag siab tob txog lub zog txuag lub qhov rooj thiab qhov rais, koj tuaj yeem pom qhov no hauv ntau daim ntawv tshaj tawm rau kev muag vaj tsev:
"Lub qhov rooj thiab qhov rais ntawm ib lub tsev siv lub zog-txuag qhov rooj thiab qhov rais ntawm ib hom ntawm thermally insulated choj-breaking aluminium profiles" los yog "Lub qhov rooj thiab qhov rais ntawm ib lub tsev siv lub zog-txuag qhov rooj thiab qhov rais ntawm ib yam hom ntawm Low-E insulating iav. "
Raws li rau lub zog-txuag qhov rooj thiab qhov rais, lawv puas yog lub zog txuag lub qhov rooj thiab qhov rais uas tsuas yog siv qhov sib tsoo-txiav choj profiles lossis tsuas yog siv Low-E insulating iav? Lub qhov rooj thiab qhov rais tiag tiag yog dab tsi?
Qhov hu ua tiag tiag lub zog-txuag system qhov rooj thiab qhov rais tsis yog siv ib qho kev faib choj aluminium profiles lossis Low-E insulating iav zog-txuag cov ntaub ntawv. Nws yog kev sib xyaw ua ke zoo tshaj plaws ntawm ib qho system. Cov txiaj ntsig ntawm kev ua tau zoo ntawm txhua qhov txuas yog qhov tseem ceeb los ntsuas seb lub tsev qhov rooj thiab qhov rais puas muaj zog txuag. Peb lub ntsiab tseem ceeb yuav tsum tau xav txog, xws li cua sov convection, tshav kub conduction thiab hluav taws xob hluav taws xob:
Kev poob ntawm cov cua sov yog cov cua kub thiab cua txias los ntawm qhov sib txawv ntawm lub qhov rooj thiab qhov rais, uas pauv cov cua sov los ntawm cov pa roj convection, uas ua rau cov cua sov poob;
Thermal conduction yog lub tshav kub hloov pauv los ntawm kev txav molecular ntawm cov khoom siv hauv qhov rooj thiab qhov rais. Nws yog pauv los ntawm ib qho chaw ntawm cov khoom nws tus kheej mus rau lwm qhov chaw, ua rau kub poob;
Radiation feem ntau yog kis ncaj qha rau hauv daim duab ntawm lub rays, ua rau lub zog poob.
Ua ntej, xaiv cov profiles ntawm cov khoom sib txawv. Lawv cov khoom sib txawv. Qhov sib txawv tseem ceeb yog thermal conductivity coefficient uas txiav txim siab lub zog noj ntawm lub qhov rooj thiab qhov rais. Thaum koj xaiv cov khoom siv, kev tsim ntawm ntu profile tseem ceeb heev.
Lub tshav kub-insulating strips ntawm lub thav duab thiab cov khoom siv kiv cua tsis nyob rau tib sab (txawm sab nraum zoov lossis sab hauv tsev), yog li tom qab cov khoom siv kho vajtse raug teeb tsa, cov ntaub ntawv sab hauv thiab sab nraum zoov txuas rau ib leeg los ntawm cov khoom siv hlau fittings bypassing. tshav kub-insulating strips, yog li tso cai rau cua sov kom sai thiab cuam tshuam rau lub qhov rooj thiab qhov rais. zog-txuag kev ua tau zoo thiab lwm yam.
Peb paub tias lub zog poob feem ntau yog tshwm sim los ntawm convection, conduction, thiab hluav taws xob. Cov iav feem ntau poob lub zog vim hluav taws xob thermal, yog li thaum peb xaiv lub tsev qhov rooj thiab qhov rais iav, kom ntseeg tau tias lub zog txuag ntawm tag nrho lub tsev, peb yuav tsum xaiv iav kom tsim nyog. Siv cov cheeb tsam yav qab teb ua piv txwv. Cov cheeb tsam yav qab teb yog thaj chaw uas muaj lub caij ntuj sov sov thiab lub caij ntuj sov sov, thiab lub voj voog kub kub yog qhov ntev. Thaum xaiv iav, koj tsis tuaj yeem xaiv iav pob tshab nrog lub teeb pom kev zoo zoo li hauv qhov chaw txias txias. Koj yuav tsum xaiv cov uas tsis tshua muaj kev cuam tshuam los ntawm cov cua sov, xws li cov txheej txheem cua sov. Insulating iav thiab Low-E insulating iav, thiab lwm yam. Nyob rau hauv kev teb rau cov kev xav tau ntawm cov tsev sib txawv nyob rau hauv ntau qhov chaw, iav nrog coj mus rau tshav kub coefficients thiab shading coefficients yog xaiv.
Peb ib zaug hais tias: "Hardware accessories yog lub plawv ntawm lub qhov rooj thiab qhov rais, tsis txhawb lub luag hauj lwm." Txawm hais tias tus txiv neej lub caj pas zoo npaum li cas thiab nws lub ntsej muag zoo li cas, yog tias nws lub siab tsis muaj zog, nws puas yuav yog tus neeg tsis muaj txiaj ntsig? Tib yam muaj tseeb rau qhov rooj thiab qhov rais. Cov khoom siv kho vajtse ua lub luag haujlwm tseem ceeb hauv lub zog txuag lub qhov rooj thiab qhov rais. Lawv tsis tsuas yog cuam tshuam nrog airtightness, watertightness thiab cua siab tsis kam ntawm lub qhov rooj thiab qhov rais, tab sis kuj ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb thiab lwm yam kev ua haujlwm.
Cov ntsiab lus yav dhau los yog qhov yuav tsum tau ua rau ntau yam khoom siv rau lub qhov rooj thiab qhov rais. Kev xaiv cov khoom tsim nyog yog qhov tseem ceeb heev, thiab qhov tseeb thiab tsim nyog ua ke ntawm ntau yam khoom siv rau hauv lub cev yog qhov ua tiav lub zog txuag lub qhov rooj thiab qhov rais. Yog li ntawd, lub qhov rooj thiab qhov rais qhov rooj sib dhos muaj zog thiab muaj kev paub dhau los kuj tseem ceeb heev. ntawm.
Los ntawm kev txheeb xyuas saum toj no, peb paub tias rau lub zog txuag lub qhov rooj thiab qhov rais, nws tsis txaus tsuas yog siv cov profiles zoo lossis iav thiab cov khoom siv. Kev sib xyaw ua ke zoo tshaj plaws ntawm cov ntaub ntawv zoo yog lub hauv paus ntawm kev ntsuas kev ntsuas ntawm qhov system.
