Txais tos mus yuav cov khoom zoo thiab customized los ntawm peb lub hoobkas. Peb yuav muab kev pabcuam zoo tshaj plaws thiab xa khoom sai rau koj.
Dab tsi yog PU Pre-insulated Rectangular Ductwork?
Nws yog ib hom HVAC huab cua faib qhov chaw uas cov phab ntsa duct yog cov vaj huam sib luag sib xyaw. Lub hauv paus yog ua los ntawmPolyurethane (PU) ua npuas ncauj, uas yog sandwiched ntawm ob txheej - feem ntau yog ib txheej txheej ntawm txhuas ntawv ci (los yog lwm yam hlau) thiab ib txheej sab hauv ntawm cov ntawv ci txhuas. Lo lus "pre-insulated" txhais tau hais tias cov rwb thaiv tsev thermal yog ib feem tseem ceeb ntawm lub vaj huam sib luag, tsis ntxiv tom qab li qhwv.
Kev tsim kho & khoom siv
Khoom siv tseem ceeb (PU Foam):
Hom:Rigid polyurethane ua npuas ncauj, feem ntau yog kaw - cell qauv nrog qhov ceev ntawm 40-48 kg / m³.
Khoom:Tshwj xeeb thermal insulator, lub teeb yuag, siab compressive zog, thiab ya raws -resistant.
Inner & Outer Facings:
Feem ntau, ob tog yogaluminium ntawv ci(60-80 microns tuab)
Cov txheej sab hauv (cua rau sab sab) yog feem ntau du kom txo tau kev sib txhuam thiab tiv thaiv microbial kev loj hlob. Cov txheej txheej sab nrauv tuaj yeem ruaj khov rau kev tiv thaiv txhua yam.
Vim li cas thiaj xaiv PU Pre- insulated Rectangular Ductwork
| Feature | Tau txais txiaj ntsig |
|---|---|
| Superior Thermal rwb thaiv tsev | PU ua npuas ncauj muaj λ=0.020 W/m·K, qis dua fiberglass lossis ntxhia ntaub plaub. Tsawg kub nce / poob. |
| Tsis muaj Thermal Bridging | Tsis muaj hlau-rau-hlau sib cuag los ntawm phab ntsa, tsis zoo li sab nraud qhwv hlau ducts. |
| Leakage Airtightness | Cov pob qij txha thiab cov ntawv ci txuas ntxiv mus ua tiav cov pa xau tsawg heev (chav A lossis B rau cov qauv SMACNA). |
| Lub teeb | Qhov ceev ~ 1.3-2 kg / m² (rau 20-30mm thickness) vs. ntawv hlau + lagging. Ua kom yooj yim dua, kev txhawb nqa tsis zoo. |
| Corrosion & Moisture Resistant | Kaw- cell foam tsis nqus dej; aluminium foil resists xeb. Tsis muaj pwm loj hlob ntawm qhov chaw. |
| Kev huv huv | Smooth sab hauv (tsis tshua muaj kev sib txhuam, plua plav tawm tsis kam) haum rau chav huv, tsev kho mob, zaub mov. |
| Kev teeb tsa ceev ceev | Tsis muaj rwb thaiv tsev, vapor barrier, los yog cladding -ib - kauj ruam los ua ke. Txiav lub sij hawm tsim los ntawm ~ 50-70% piv rau cov hlau ducts. |
| Suab nrov Absorption | PU ua npuas ncauj muab qee lub suab damping, txo cov kiv cua thiab lub suab nrov tsis tas yuav tsum tau ntxiv cov acoustic hauv ob sab phlu. |
| Chaw Txuag | Thinner zuag qhia tag nrho phab ntsa (20–30mm raug) piv rau hlau duct + 50mm sab nraud rwb thaiv tsev, txuag qab nthab plenum qhov siab. |
