Tus nqi dej ntws (WVTR) ntawm cov khoom rwb thaiv tsev yog ib qho tseem ceeb uas yuav tsum xav txog thaum tsim thiab tsim cov tsev. WVTR yog tus nqi uas cov dej ntws hla cov khoom siv xws li cov khoom rwb thaiv tsev, thiab feem ntau ntsuas hauv grams/square meter/hnub. Kev nkag siab txog WVTR ntawm cov khoom rwb thaiv tsev tuaj yeem pab cov kws kes duab vajtse, cov engineers thiab cov neeg cog lus txiav txim siab txog cov khoom siv zoo tshaj plaws los siv hauv cov tsev kom tiv thaiv cov teeb meem ntsig txog dej noo.
Kev rwb thaiv cua sov ua lub luag haujlwm tseem ceeb hauv kev tsim kom muaj ib puag ncig sab hauv tsev uas xis nyob thiab txuag hluav taws xob. Nws pab tswj qhov kub thiab txias hauv lub tsev thiab txo qhov hloov pauv cua sov ntawm sab hauv thiab sab nraud. Txawm li cas los xij, kev rwb thaiv cua sov kuj tseem yuav tsum tswj kev txav mus los ntawm cov dej noo kom tiv thaiv cov teeb meem xws li kev loj hlob ntawm pwm, lwj, thiab txo qis kev ua haujlwm ntawm kev rwb thaiv cua sov nws tus kheej.
Cov ntaub ntawv rwb thaiv tsev sib txawv muaj cov nqi WVTR sib txawv. Piv txwv li, cov khoom rwb thaiv tsev ua npuas dej feem ntau muaj WVTR qis dua piv rau cov khoom rwb thaiv tsev fiberglass lossis cellulose. Qhov no txhais tau tias nws tsis yooj yim rau cov pa dej nkag, ua rau muaj kev tswj hwm cov av noo zoo dua hauv cov tsev. Txawm li cas los xij, WVTR ntawm cov ntaub ntawv rwb thaiv tsev tsis yog tib qho uas yuav tsum xav txog thaum xaiv cov khoom siv zoo. Lwm yam, xws li huab cua ntawm lub tsev, qhov muaj cov pa dej thaiv thiab kev tsim qauv tsev tag nrho, kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tswj cov av noo.
Nws yog ib qho tseem ceeb uas yuav tsum nrhiav kev sib npaug ntawm kev tswj cov av noo thiab kev ua pa kom zoo. Cov tsev uas kaw dhau yuav ua rau cov av noo nyob hauv, ua rau muaj teeb meem av noo thiab ua rau lub tsev puas tsuaj. Ntawm qhov tod tes, cov tsev uas muaj qhov dej nkag tau tuaj yeem ua rau cov av noo ntau dhau nkag mus rau hauv, ua rau muaj teeb meem zoo sib xws. Kev nkag siab txog WVTR ntawm cov khoom siv rwb thaiv tsev tuaj yeem pab cov kws kes duab vajtse thiab cov neeg ua vaj tse nrhiav kev sib npaug kom tau raws li cov kev xav tau tshwj xeeb ntawm lub tsev.
Thaum huab cua txias, nws yog ib qho tseem ceeb uas yuav tsum siv cov khoom rwb thaiv tsev uas muaj WVTR qis dua kom tiv thaiv kom tsis txhob muaj dej noo hauv phab ntsa lossis ru tsev. Cov dej noo tuaj yeem ua rau pwm loj hlob, ua rau muaj kev pheej hmoo rau kev noj qab haus huv rau cov neeg nyob hauv, thiab ua rau cov khoom siv hauv tsev puas tsuaj raws sijhawm. Hauv huab cua sov, cov khoom rwb thaiv tsev uas muaj WVTR siab dua yuav tsim nyog dua kom cov dej noo tawm thiab tiv thaiv kom tsis txhob muaj dej noo ntau dhau.
Feem ntau ntsia rau sab sov ntawm cov khoom rwb thaiv tsev, cov khoom thaiv dej kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tswj cov dej noo. Lawv pab tswj kev txav ntawm cov dej pa thiab tiv thaiv nws kom tsis txhob nkag mus rau hauv lub tsev. Kev nkag siab txog WVTR ntawm cov khoom rwb thaiv tsev thiab cov khoom thaiv dej yog qhov tseem ceeb rau kev ua kom muaj kev tswj cov dej noo hauv lub tsev.
Hauv kev xaus lus, qhov ceev ntawm kev kis cov dej ntawm cov khoom rwb thaiv tsev ua lub luag haujlwm tseem ceeb hauv kev tswj cov dej noo hauv lub tsev. Los ntawm kev nkag siab txog WVTR ntawm cov khoom siv rwb thaiv tsev sib txawv thiab xav txog lwm yam xws li huab cua thiab kev tsim qauv tsev, cov kws kes duab vajtse, cov engineers thiab cov neeg cog lus tuaj yeem txiav txim siab zoo txog cov khoom rwb thaiv tsev zoo tshaj plaws rau ib qho project tshwj xeeb. Qhov no pab tiv thaiv cov teeb meem ntsig txog dej noo thiab tsim kom muaj ib puag ncig sab hauv tsev zoo, noj qab haus huv, thiab txuag hluav taws xob rau cov neeg nyob hauv tsev.
