Lub tshuab hluav taws xob ua ntej hvac (cua sov, qhov cua txias) thiab cua txias sawv cev rau kev nce qib kev nyab xeeb hauv tsev. Ntawm nws cov tub ntxhais, cov kab ke no ua ke rwb thaiv tsev ncaj qha rau hauv HVAC Cheebtsam, feem ntau ductions thiab kav dej, thaum lub sij hawm tsim khoom, ntau dua li thov rwb thaiv tsev nyob rau hauv.
Cov ntaub ntawv rwb thaiv tsev siv nyob rau hauv pre-insulated hvac cov qauv yog ua tib zoo xaiv rau lawv cov kev ua tau zoo tshaj. Cov kev xaiv ib txwm muaj xws li phenolic ua npuas dej, polyurethane (pu), thiab polyisocyanurate (pir). Piv txwv li npuas, piv txwv li, yog muaj npe rau nws cov txiaj ntsig thermal (K - Tus nqi qis li {2 uas me me}. Mine}. Mine}. Mine} Qhov no txhais tau tias txawm yog lub zog cua sov lub tsev nyob hauv huab cua txias lossis lub zog tsis muaj zog, muaj nqi rau cov tswv tseem ceeb rau cov tswv thiab cov neeg ua haujlwm.
Kev nyab xeeb hluav taws yog lwm qhov tseem ceeb ntawm kev ua ntej - insulated hvac systems. Cov khoom sib txawv rwb thaiv tsev ua tau raws li sib txawv - cov qauv tsis kam. Phenol ua npuas ncauj feem ntau ua tiav chav kawm tsis yog - kev sib txuas nrog cov chaw muaj pa, cov chaw muag khoom, thiab siab - nce vaj tse. PU thiab Pir, thaum feem ntau muaj qhov qis dua hluav taws kub (chav kawm B1), tseem muaj kev tiv thaiv kom muaj kev siv hluav taws kom zoo thaum tsim nyog.
Cov xwm txheej ua ntej ntawm cov tshuab no tseem hloov cov txheej txheem kev teeb tsa. Pre-insulated ducts tuaj hauv cov ntu uas tuaj yeem sib sau ua ke ntawm lub xaib, txo cov nqi hauv nroog thiab cov khoom siv dag zog rau cov rwb thaiv tsev ntxiv tom qab kev teeb tsa. Qhov no tsis yog tsuas yog ua kom muaj sijhawm tsim kho kom zoo tab sis kuj ua kom muaj kev teeb tsa ntau dua thiab txhim khu kev qha yog meej thaum chaw tsim khoom.
Ntxiv mus, pre-insulated HVAC yog tsim los tiv thaiv ntau yam kev mob ib puag ncig. Lawv cov qauv kaw cell-rwb thaiv tsev tsis muaj kev cuam tshuam los tiv thaiv kev ua pwm thiab kev tsis txaus ntseeg ntawm kev ua haujlwm hauv lub sijhawm. Qhov kev ua tau zoo no ua rau lawv haum rau ntau cov ntawv thov, los ntawm cov tuam tsev lag luam thiab cov chaw muaj kev nyab xeeb rau cov tsev nyob, tsis hais txog ntawm cov huab cua nyob hauv ib cheeb tsam.
Hauv cov ntsiab lus, pre-insulated hvac tshuab ua ke ua ke txuag hluav taws xob ib puag ncig thaum muaj kev txhim kho sab hauv tsev thiab kev sib ntsib niaj hnub ua tsev.
