Muaj kev sib txawv. Muaj ntau ntau hom kav dej rau kev siv tsis kawg. Tib yam siv rau cov yeeb nkab sealing thiab yuav ua li cas nws cuam tshuam rau qhov system efficiency thiab txuag hluav taws xob.
Tom qab kev sim kuaj, qhov ua tau zoo ntawm HVAC system tau mus txog nws qhov siab tshaj plaws nyob rau hauv ze li qhov zoo tagnrho. Kev tsim cov txiaj ntsig no hauv lub ntiaj teb tiag tiag yuav tsum muaj kev paub thiab kev siv zog hauv kev txhim kho thiab tswj cov kab ke. Ib qho tseem ceeb ntawm kev ua tau zoo tiag tiag yog lub ductwork. Muaj ntau ntau hom duct systems rau kev siv tsis kawg. Qhov no feem ntau yog ib lub ntsiab lus uas cov neeg cog lus HVAC tuaj yeem sib cav txog. Txawm li cas los xij, lub sijhawm no kev sib tham tig mus rau kev sib khi thiab nws cuam tshuam li cas rau kev ua haujlwm ntawm lub cev thiab kev txuag hluav taws xob.
Nyob rau hauv nws txoj kev sib tw duct sealing, ENERGY STAR® ceeb toom cov tswv tsev siv cov cua txias cua txias thiab cua txias uas kwv yees li 20 mus rau 30 feem pua ntawm cov cua uas ntws los ntawm cov kav dej tuaj yeem poob vim qhov xau, qhov thiab cov kav dej tsis zoo.
"Qhov tshwm sim yog cov nqi hluav taws xob ntau dua thiab lub sijhawm nyuaj ua kom koj lub tsev nyob zoo, txawm tias lub ntsuas kub tau teeb tsa li cas," hais tias Energy Star lub vev xaib. "Kev sib khi thiab insulating ducts tuaj yeem pab daws teeb meem kev nplij siab thiab txhim kho huab cua sab hauv tsev. thiab txo backflow. " gas rau hauv qhov chaw nyob. "
Lub koom haum ceeb toom tias cov kab hluav taws xob tuaj yeem nyuaj rau kev nkag mus, tab sis tseem muab cov tswv tsev nrog daim ntawv teev npe ua-nws-koj tus kheej uas suav nrog kev tshuaj xyuas, kaw qhov qhib nrog cov kab xev los yog ntawv ci, thiab qhwv cov kav dej uas khiav los ntawm qhov chaw tsis muaj cua sov nrog rwb thaiv tsev cua ducts Tom qab ua tiav. tag nrho cov kauj ruam no, Energy Star pom zoo tias cov tswv tsev muaj cov txheej txheem tshuaj xyuas los ntawm tus kws tshaj lij. Nws kuj tseem cia cov tswv tsev paub tias feem ntau cov kws tshaj lij HVAC cov neeg cog lus yuav kho thiab txhim kho cov kav dej.
Raws li Lub Hnub Qub Zog, plaub qhov teeb meem feem ntau ntawm cov kav dej yog xau, ruptured, thiab cov ducts disconnected; cov ntsaws ruaj ruaj tsis zoo ntawm cov npe thiab cov hniav nyiaj hniav kub; xau hauv qhov cub thiab lim tais; thiab kinks hauv cov kav dej hloov tau yooj yim uas txwv tsis pub huab cua ntws. Kev daws teeb meem no suav nrog kev kho cov kav dej thiab kev sib khi; xyuas kom nruj haum ntawm cov ntawv sau npe thiab cov hniav nyiaj hniav kub rau cov cua ducts; sealing furnaces thiab lim troughs; thiab kom zoo insulating ductwork nyob rau hauv qhov chaw tsis tiav.
Duct sealing thiab rwb thaiv tsev ua haujlwm ua ke los tsim kev sib raug zoo symbiotic uas ua rau kom muaj txiaj ntsig thiab kev nplij siab.
"Thaum koj tham txog ductwork, yog tias nws tsis raug kaw zoo, lub rwb thaiv tsev yuav tsis ua nws txoj haujlwm," said Brennan Hall, tus thawj coj ntawm HVAC cov khoom lag luam loj ntawm Johns Manville Performance Materials. "Peb mus koom tes nrog kev sib khi cov kav dej."
Nws piav qhia tias thaum lub kaw lus kaw lawm, lub rwb thaiv tsev xa cov cua kub uas yuav tsum tau ua los ntawm cov cua tuav los ntawm cov ducts, txuag hluav taws xob nrog qhov tsawg tshaj plaws kom poob los yog nce, nyob ntawm seb hom xaiv.
Hall hais tias "Yog tias tsis muaj qhov poob los yog nce ntxiv thaum nws dhau los ntawm cov ducts, nws yuav pom tseeb tias yuav pab nce qhov kub thiab txias hauv lub tsev los yog lub tsev mus rau qhov xav tau qhov ntsuas kub ntawm qhov xav tau," Hall hais. "Lub kaw lus yuav nres thiab cov kiv cua yuav tsum tsis ua haujlwm, uas yuav pab txo cov nqi hluav taws xob."
Qhov thib ob tshwm sim ntawm kev sib khi ducts kom zoo yog kom txo qis condensation. Kev tswj cov condensation thiab noo noo ntau dhau yuav pab tiv thaiv pwm thiab tsw tsw.
Hall hais tias "Lub vapor barrier ntawm peb cov khoom, txawm tias nws yog duct film lossis ductwork, ua rau muaj qhov sib txawv loj," Hall hais. "John Manville duct panels txo lub zog poob los ntawm kev txwv tsis pub lub suab nrov thiab tswj xyuas qhov kub thiab txias. Lawv kuj pab tsim kom muaj kev noj qab nyob zoo hauv tsev los ntawm kev txo cov pa tawm thiab tiv thaiv kev puas tsuaj los ntawm kev loj hlob microbial. "
Lub tuam txhab tsis tsuas yog pab cov neeg cog lus los ntawm kev tsim ntau yam khoom los daws cov teeb meem ntawm lub suab nrov thiab kev ua haujlwm zoo, tab sis kuj tau tsim cov kev cob qhia dawb hauv online ntawm nws cov HVAC thiab cov kev daws teeb meem hluav taws xob.
"Lub Johns Manville Academy muaj cov kev qhia sib tham sib tham uas piav qhia txhua yam los ntawm cov hauv paus ntawm cov txheej txheem rwb thaiv tsev kom muag thiab nruab Johns Manville HVAC cov tshuab thiab cov khoom siv tshuab," Hall hais.
Bill Diederich, Aeroseal tus lwm thawj coj ntawm kev ua haujlwm hauv vaj tse, hais tias kev sib khi ducts yog txoj hauv kev zoo tshaj plaws los ua kom muaj txiaj ntsig zoo ntawm koj cov khoom siv.
Sealing los ntawm sab hauv: Aeroseal cov neeg cog lus txuas cov kav dej tiaj tus mus rau cov kav dej. Thaum lub zog khi tau nias, lub raj ntim tiaj tus yog siv los xa cov seaving nti rau hauv cov txheej txheem duct.
Nws tau hais tias "Qhov tseeb, hauv cov phiaj xwm rov ua dua tshiab, kev sib khi ductwork tuaj yeem txo qhov loj me, ua rau cov cua sov thiab cua txias me me, qis dua thiab cov cua txias," nws hais. "Kev tshawb fawb qhia tau hais tias txog li 40% ntawm cov huab cua coj mus rau hauv lossis tawm ntawm chav tsev tau ploj vim los ntawm kev xau hauv cov kav dej. Raws li qhov tshwm sim, HVAC cov tshuab yuav tsum tau ua haujlwm hnyav dua thiab ntev dua li niaj zaus kom ua tiav thiab tswj kom zoo hauv chav sov. Sij hawm dhau los Los ntawm kev tshem tawm cov dej xau, HVAC cov tshuab tuaj yeem ua haujlwm ntawm qhov ua tau zoo tshaj plaws yam tsis muaj hluav taws xob los yog txo cov khoom siv lub neej. "
Aeroseal seals ducts feem ntau los ntawm sab hauv ntawm cov kav dej es tsis yog los ntawm sab nraud. Qhov qhov tsawg dua 5/8 nti hauv txoj kab uas hla yuav raug kaw siv Aeroseal system, uas yog tsim los ua kom yooj yim rau cov txheej txheem sealing yeeb nkab tau piav qhia saum toj no.
Kev Npaj Cov Yeeb Nkab: Npaj cov kav dej rau kev sib txuas rau Aeroseal ca tubing. Thaum lub zog khi tau nias, lub raj ntim tiaj tus yog siv los xa cov seaving nti rau hauv cov txheej txheem duct.
Diederich hais tias "Los ntawm kev txhaj tshuaj txau rau hauv cov kav dej hauv qab lub siab, Aeroseal seals ducts los ntawm sab hauv txawm tias lawv nyob qhov twg, suav nrog cov ducts nkag tsis tau tom qab phab ntsa ntub dej," hais tias Diederich. "Lub kaw lus software taug qab txo qis hauv lub sijhawm tiag tiag thiab muab daim ntawv pov thawj ntawm kev ua tiav ua ntej thiab tom qab xau."
Txhua qhov xau loj dua 5/8 nti tuaj yeem kaw los ntawm tes. Cov dej xau loj, xws li cov kav dej tawg, tawg lossis puas lawm, yuav tsum tau kho ua ntej sib khi. Raws li lub tuam txhab, cov neeg cog lus yuav txheeb xyuas cov teeb meem no los ntawm kev tshuaj xyuas qhov muag ua ntej sib khi. Yog tias pom muaj teeb meem loj thaum lub sij hawm thov ntawm Aeroseal Duct Sealing Spray, lub kaw lus yuav tsum tam sim ntawd nres kom tsis txhob ntws cov sealant, xyuas qhov teeb meem thiab muab kev daws teeb meem rau ntawm qhov chaw ua ntej rov pib sealing.
"Ntxiv rau qhov ua tau zoo dua, cov neeg siv khoom yuav pom tias kev sib khi lawv cov ducts tshem tawm qhov tsis xis nyob thiab qhov kub tsis sib xws hauv lawv lub tsev; tiv thaiv cov plua plav los ntawm kev nkag mus rau hauv cov ducts, huab cua tuav thiab cov pa uas lawv ua pa; thiab tuaj yeem txo cov nqi hluav taws xob txog li 30 feem pua. " hais. "Nws yog txoj hauv kev yooj yim tshaj plaws thiab ua tau zoo tshaj plaws rau cov tswv tsev los txhim kho huab cua thiab cua hauv lawv lub tsev, ua kom muaj kev nplij siab thiab huab cua zoo thaum txuag hluav taws xob thiab txo cov nqi hluav taws xob."
