PIR rwb thaiv tsev ducting

PIR Rwb thaiv tsev Ducting xa cov siab -kev ua tau zoo, ib puag ncig kev nyab xeeb huab cua faib rau HVAC niaj hnub. Tsim los ua ib lub vaj huam sib luag sib xyaw nrog aluminium ntawv ci ntsib thiab nruj PIR ua npuas ncauj tub ntxhais, lawv ua tau zoo dua cov kab hluav taws xob galvanized steel ducts xav tau ntawm - qhov chaw rwb thaiv tsev. Featuring tsis tshua muaj zog poob thiab eco- qauv tsim tus phooj ywg, lawv txhawb kev txuag hluav taws xob thiab ua tau raws li lub tsev ntsuab. Zoo tagnrho rau tsev so, chaw ua haujlwm complexes, tshav dav hlau, tsev kho mob thiab lwm lub tsev lag luam thiab pej xeem.

Nws Yog Dab Tsi

Lub duct yog ib lub vaj huam sib luag nrog cov qauv sandwich:

Core Khoom:Lub hauv paus yog ua los ntawmPolyisocyanurate (PIR)ua npuas ncauj, nruj, kaw -cell thermosetting yas . Qhov no yog qhov tseem ceeb ntawm cov khoom siv ua haujlwm.

Facings:PIR ua npuas ncauj tub ntxhais yog sib txuas ntawm ob sab rau txheej tiv thaiv, feem ntau yog txhuas ntawv ci, txhuas ntawv, los yog ua ntej- pleev xim rau galvanized (GI) steel . Lub ntsej muag muab kev txhawb nqa kev tsim kho thiab vapor barrier.

Cov khoom siv tseem ceeb thiab kev rwb thaiv tsev ntawm PIR Insulation Ducting

Cov khoom siv tseem ceeb ntawm cov ntawv prefabricated PI rwb thaiv tsev cua duct yog hloov kho polyisocyanurate (PI) ua npuas ncauj. Qhov sib txawv ntawm cov khoom siv hluav taws xob PU zoo sib xws, lub nplhaib molecular qauv yog ntom, thiab kaw -tus nqi ntawm tes tuaj yeem ncav cuag 93% mus rau 96%. Kev ntsuas thermal conductivity yog 0.021 txog 0.023 W / (m・K). Nyob rau hauv ib txwm kub kub ntawm 23 degree, cov nyhuv rwb thaiv tsev ntawm tib tuab yog kwv yees li 12% zoo dua li ntawm PU zoo tib yam. Ib daim ntawv tuab 25 hli tuaj yeem ua tau raws li cov txheej txheem rwb thaiv tsev rau cov cua txias hauv nruab nrab cov kav dej, thiab 50mm specification yog tsim rau qis - huab cua ntshiab thiab qis - cov txheej txheem kub ntawm cov ducts.

Qhov kom zoo dua ntawm siab -kub tsis kam yog qhov tseem ceeb. Qhov ntev -lub sij hawm siv tsis tu ncua kub yog 130 degree, thiab luv luv -lub sij hawm ncov kub yog 150℃. Qhov no tshem tawm cov teeb meem ntawm npuas shrinkage thiab delamination nyob rau hauv siab - qhov kub thiab txias ib puag ncig, thiab yog haum rau siab - qhov kub thiab txias tso pa tawm, chav ua noj chav ua noj, thiab composite cua duct scenarios rau ua noj pa luam yeeb, zam lub drawbacks ntawm siab - kub softening thiab tsis ua hauj lwm ntawm roj hmab thiab XPS.

Thermal Performance and Energy Efficiency ntawm PIR Rwb thaiv tsev Ducting

Lub ntsiab kom zoo dua yog qhov tsis tshua muaj thermal conductivity, λ=0.018–0.02 W / m·K (20 degree), uas yog qhov zoo dua li iav ntaub plaub (λ ≈ 0.040), pob zeb wool (λ ≈ 0.038), thiab zoo tib yam PU (λ ≈ 0.023).

Lub thermal tsis kam ntawm 20mm board yog kwv yees li R ≈ 0.91 m²·K / W, ua tau raws li cov qauv kev rwb thaiv tsev rau feem ntau cov tuam tsev lag luam 'HVAC systems; piv rau cov ntawv hlau galvanized ib txwm muaj + cov khoom siv hluav taws xob sab nraud, lub zog txuag hluav taws xob tuaj yeem ncav cuag 25% -30%, txo qhov hnyav ntawm lub tshuab cua txias thiab kev siv hluav taws xob.

Lub kaw-cov qauv ntawm tes muaj qhov nqus dej <1% (los ntawm ntim), thiab cov ntawv txhuas txhuas ua haujlwm ruaj khov vapor barrier, tiv thaiv condensation los ntawm qhov chaw thiab tsim nyog rau thaj chaw ntub dej.
