Pir HVAC duct Sheet: High - Ua tau kev daws teeb meem rau kev ua haujlwm zoo
Pir HVAC duct sawm (luv rauPolyisocyanurate HVAC ducr ntawv) yog ib pawg neeg tshwj xeeb, sib xyaw ua ke muaj kev sib xyaw rau cov ntaub cua sov, qhov cua, thiab cua txias (HVAC) duct tshuab. Tsis zoo li ib txwm ductwork - qhov twg hlau rwb thaiv tsev, thiab npaj} {{{}}}} siv cov khoom. Nws tau dhau los ua cov khoom lag luam hauv kev lag luam, kev lag luam, thiab cov chaw haujlwm, tsev kho mob, cov ntaub ntawv, cov ntaub ntawv, cov ntaub ntawv, cov ntaub ntawv, cov ntaub ntawv, cov ntaub ntawv, cov ntaub ntawv, yooj yim ntawm kev teeb tsa, thiab kav ntev.
Dab tsi ua rau Pir HVAC duct ntawv ua haujlwm ??
Txhua txhua Pir HVAC duct cov ntawv yog ib tug txheej txheem fawm kib engineered rau hvac - kev xav tau. Nws peb qhov tseem ceeb ua haujlwm hauv tandem xa kev ua tau zoo thiab ntseeg tau:
Rwb thaiv tsev tub ntxhais:
Rigid Pir Ua Npuas Ncauj, ib qho kev kaw - cell, thermoset yas nrog excittional thermal tiv thaiv. Nws me me cua / txias cua poob ntawm ducts, # 1 ua rau ntawm HVAC lub zog pov tseg.
Cov rooj tshav puam:
Feem ntau mas ntawv ci, pre - painted galvanized steel (ppgi), lossis aluminium ntawv. Cov kev ua no raws li:
{{0 {{}} huab cua barrier (tiv thaiv duct dej)
{{0- vapor Barrier (nres noo noo tsim / pwm)
{{0- Cov qauv kev ua haujlwm (tawm tsam puntures / corrosion).
Vim li cas thiaj xaiv Pir HVAC duct daim ntawv tshaj cov ntoo galvanized steel ductions?
Piv rau tsoos hlau + fiberglass lossis lwm yam insulated duass (piv txwv li, phenol ua npuas ncauj), PIR HEFAC duct cov ntawv sau tau zoo dua ntawm cov tswv cuab:
Txo kev ua haujlwm thiab lub zog cov nqi offset me ntsis siab dua cov khoom siv tshiab dua.
Tsawg dua kev kho thiab cov neeg hu rov qab (tsis muaj xeb, pwm, lossis rwb thaiv tsev rwb thaiv tsev).
Yooj yim ua raws li cov kev cai tshiab thiab iAq kev cai.
Nyob rau hauv luv luv, Pir HVAC duct, yav tom ntej {{{{} e} Cov ntaub ntawv pov thawj uas xav tau kev ua tau zoo, durability, thiab yooj yim ntawm kev teeb tsa.
Cov kev siv ntawm Pir HVAC duct nplooj ntawv:
Pir HVAC duct daim ntawv yog qhov kev xaiv zoo tshaj plaws rau cov phiaj xwm qhov twg ua tau zoo, nrawm, thiab kev ntseeg tau yog tsis yog {sib ceg:
Cov tsev lag luam: Chaw ua haujlwm, khw muag khoom, chaw ntiav pw, thiab tshav dav hlau.
Kev Kho Mob: Tsev kho mob, chaw kuaj mob, thiab lab (yuav tsum tau pwm {{free, yooj yim {{2} - ntxuav dhuav).
Cov chaw zov me nyuam: tswj cov chaw kub ruaj khov rau cov khoom siv nkag.
Cov chaw muaj: Chaw ua haujlwm, chaw khaws khoom, thiab khoom txias (tiv taus cov chaw hnyav).
Cov tuam tsev: Cov Tsev Kawm Ntawv, Qib Siab, thiab Tsoomfwv Cov Chaw (Ntev {}}}}}}}}}}}}}}}}}}}}}}}} Lub sijhawm raug nqi txuag).
