Yog tias koj tab tom npaj cov kev tsim kho tshiab, kev kho tsheb HVAC, xaiv txoj cai Devernade, Xaiv txoj cai Deverny yog qhov tseem ceeb rau ntev} Kev nplij siab, txuag lub zog txuag, thiab txuag kev txuag hluav taws xob, thiab kev txuag nyiaj lub zog, thiab kev txuag nyiaj txiag, thiab kev txuag nyiaj txiag, thiab kev txuag nyiaj txiag, thiab kev txuag nyiaj txiag, thiab kev txuag nyiaj txiag, thiab kev txuag nyiaj. Polyurethane ua ntej- Insulated devwork sawv kom tau raws li qhov xav tau ntawm cov tsev tshiab, chaw haujlwm, chaw lag luam, thiab cov chaw lag luam, thiab cov chaw lag luam, thiab cov chaw lag luam, thiab cov chaw lag luam, thiab cov chaw lag luam, thiab cov chaw lag luam, thiab cov chaw lag luam, thiab cov chaw lag luam, thiab cov chaw lag luam Ntawm no yog vim li cas nws yog qhov kev xaiv zoo tshaj plaws rau koj qhov project:

Dab tsi ua rau polyurethane duterwork tshwj xeeb?

Polyurethane ua ntej - edulated dured

yog lub Hoobkas -}} Cov Cheeb Tsam Cell Hauv Ib qho: Lub Rwb Thaiv Tsev (Cov khaubncaws sab nraud povtseg (sab nraud).

Qhov no txhua {- hauv - Ib tus qauv tshem tawm qhov xav tau ntawm kev teeb tsa kev sib cais, ua kom tau zoo ib yam thiab ua tau zoo los ntawm hnub ib.

1. Zoo txuag txuag

Polyurethane ua npuas ncauj tau zoo heev ntawm kev ua kom kub hauv lossis tawm. Nws muaj tsawg thermal conductivity (li 0.020 w / min k).
Qhov no txhais tau tias:

Tsawg me me poob lossis nce: cov cua uas txias (nyob rau lub caij ntuj sov) lossis sov (nyob rau lub caij ntuj no) ua kom nws kub thiab txias los ntawm cov ducts. Yog li koj HVAC system tsis tas yuav ua haujlwm li nyuaj.

Cov nqi hluav taws xob qis dua: piv rau qub - Style Hlau Ducts uas tsis muaj rwb thaiv tsev, polyurethane ducts txiav hluav taws xob pov tseg los ntawm li 35%. Sij hawm dhau los, cov nyiaj uas koj khaws cia rau cov nqi txhua hli yuav them tus nqi ntawm ducts.

2. Tsis muaj huab cua xau thiab ntev -} kav

Tsis tshua muaj huab cua cua sov: cov nqaws ua tib zoo ua rau thiab cuam tshuam nrog pob qij txha sib foob nruj. Cov dej xau tsuas yog 1-2% (ntau qis dua li 10-15% ntawm cov hlau ducts). Yog li txhua tus txias txias lossis cua sov tau txais qhov uas nws yuav tsum mus, ua koj qhov chaw xis nyob dua.

Xeem lub sijhawm ntev: lub kaw - Kev ua npuas ncauj ntawm tes ua npuas dej tsis txhob noo, yog li nws yuav tsis tau txais cov chaw ntub dej (zoo li chav ua noj, lossis ze ntawm ntug dej hiav txwv). Cov txheej txheem sab nraud lossis cov txheej sib xyaw tiv thaiv kev tiv thaiv dents, xeb, thiab hnav. Nrog me upkeep, nws tuaj yeem kav 20+ xyoo.

3. Nyob ntsiag to thiab huv si huab cua txaus

Tsawg lub suab: cov tub ntxhais ua npuas ncauj thaiv cov suab, yog li koj yuav tsis hnov ​​ntau cov cua txav los ntawm lub system. Tsis muaj suab nrov dua, rattling ductions - Koj yuav muaj ib qho chaw, txias.

Cov huab cua huv sab hauv tsev: Cov kab khawb av uas tsis khov sab hauv cov ducts nres plua plav los ntawm kev tsim thiab cov kab mob los ntawm loj hlob. Qhov no ua rau cov huab cua ntws los ntawm kev huv thiab noj qab haus huv {{1} Zoo meej rau cov tsev nrog cov neeg uas tau ua xua, chaw haujlwm, lossis tsev kho mob.

4. Ceev thiab yooj yim rau nruab

Qub {- nkhaus hlau ducts xav tau txiav, vuam, thiab rwb thaiv tsev ntxiv rau ntawm- chaw. Tab sis polyurethane ducts tuaj ua ntej- ua kom haum koj txoj haujlwm raws nraim.
Qhov no txhais tau tias:

Lub sijhawm luv luv (cov neeg ua haujlwm tuaj yeem tso cov kab ke ua ke nrog cov cuab yeej yooj yim. Qhov kev txiav cov nqi zog no thiab tsis muaj kev ntxhov siab rau koj lub sijhawm ntau dhau (zoo rau cov sijhawm kaw ntom nti lossis cov chaw uas twb tau siv lawm).

Haum rau ib qho txheej txheem: koj tuaj yeem tau txais nws hauv cov ncaj, luj tshib, Tees, thiab cov qauv kev cai. Nws haum tau yooj yim hauv qab nthab, phab ntsa, lossis me me fab- zoo rau cov tsev tshiab thiab cov tuam tsev qub.

5. Zoo rau ib puag ncig thiab ua tau raws cov cai

Eclo {{{0} Kev xaiv tus phooj ywg: Polyurethane ua npuas ncauj tsis muaj CFCs (uas ua mob rau OZone txheej), yog li nws ua raws cov cai hauv tsev ntsuab. Nws lub zog txuag nyiaj kuj pab txo koj cov hneev taw.

Ntsib cov kev cai nruj: Nws ua raws kev nyab xeeb thoob ntiaj teb thiab kev ua tau zoo. Qhov no suav nrog kev tiv thaiv hluav taws (kuaj rau ASTM thiab en cov qauv) thiab airtightnesss. Yog li cov tswv tsev, cov thawj tswj hwm tsev, thiab cov kws kuaj xyuas tuaj yeem ntseeg tau txog nws.

Seb koj puas tau ua haujlwm hauv tsev, chaw muag khoom, chaw muag khoom, polyurethane pre - Insulated Dev Kev Ua Si rau koj cov kev xav tau:

Thaj: Khaws koj lub tsev nyob xyoo xyoo - round nrog cov nqi qis dua.

Ua lag luam: Txhim kho cov neeg ua haujlwm cov khoom lag luam nrog cov chaw kub zoo li qub thiab kev ua haujlwm ntsiag to.

Yam muaj hauj lwm: Walland tawv ib puag ncig thaum saib xyuas hluav taws xob tau zoo.

Polyurethane ua ntej - Insulated Devework tsis yog lub luag haujlwm duct Los ntawm kev xaiv nws, koj yuav txaus siab rau cov nqi qis dua, kev kho dua tsawg dua, thiab ib qho chaw uas nyob nraum xis nyob rau ntau caum xyoo.

Npaj kom txhij los hloov kho koj lub HVAC system? Nug koj tus kws ua haujlwm txog Polyurethane ua ntej- edulated ductwork hnub no {}} Koj lub zog) yuav ua tsaug rau koj.
