Txoj cai steel vaj huam sib luag radiator yog ib qho uas ua tau raws li chav tsev kub poob ntawm qhov kev npaj ua haujlwm kub thiab haum rau kev teeb tsa. Xaiv los ntawm cov tsos, qhov ntev los yog ib qho catalog wattage ib leeg tuaj yeem tawm hauv chav tsis muaj cua sov, tshwj xeeb tshaj yog thaum lub tshuab cua sov khiav ntawm cov dej qis.
Raws li steel vaj huam sib luag radiator chaw tsim tshuaj paus, peb pom zoo kom tsim cov chav xav tau thiab cov txheej txheem ua ntej. Cov txheej txheem hauv qab no siv rau cov hluav taws xob hydronic txuas nrog rau cov dej kub uas tsim nyog.
1 Tsim kom muaj chav sov poob
Pib nrog ib chav los ntawm chav tsev tsim cov cua sov tsis suav. Cov khoom tsim nyog muaj xws li lub caij ntuj no tsim qhov kub thiab txias, lub hom phiaj sab hauv tsev, sab nrauv phab ntsa, glazing, rwb thaiv tsev, qab nthab qhov siab thiab qhov cua. Ob chav nrog tib cheeb tsam hauv pem teb tuaj yeem xav tau cov cua kub sib txawv heev.
Ib cheeb tsam raws li qhov nyiaj pub dawb tuaj yeem txhawb nqa qhov kwv yees thaum ntxov, tab sis nws tsis yog txoj cai universal sizing. Piv txwv li, yog tias qhov project kwv yees kwv yees li 80 W / m², chav 20 m² muab 20 × 80=1,600 W. Cov lej lej yooj yim; seb 80 W / m² puas tsim nyog yuav tsum tau kuaj xyuas lub tsev ntawd. Siv qhov kev paub tseeb tsim load rau kev xaiv zaum kawg.
2 Muab cov zis tso rau qhov kub thiab txias
Ib daim duab tso zis hluav taws xob muaj txiaj ntsig tsuas yog nrog nws qhov kub thiab txias. Rau kev sib piv cov catalog sib piv, qhov sib txawv ntawm lub tshuab hluav taws xob yog qhov nruab nrab ntawm kev ntws thiab rov qab dej kub rho tawm hauv chav tsev. Nws tsis yog qhov txawv ntawm qhov ntws thiab rov qab dej.

Ntawm qhov sib txawv ntawm qhov kub thiab txias, tib lub radiator muab cov cua sov tsawg dua. Siv cov chaw tsim khoom xaiv cov lus tso tawm rau cov xwm txheej tiag tiag, lossis nws txoj kev pom zoo kho. Tsis txhob sib piv ib lub tshuab hluav taws xob ntsuas ntawm ΔT50 nrog rau lwm qhov ntsuas ntawm ΔT30 zoo li cov duab sib npaug.
Piv txwv ua haujlwm: xav tias lub tshuab hluav taws xob tau ntsuas ntawm 2,000 W ntawm ΔT50 thiab nws qhov kev kho qhov tsim nyog ntawm ΔT30 yog 0.51. Nws hloov kho cov zis yog 2,000 × 0.51=1,020 W, hauv qab ntawm 1,600 W chav thauj khoom hauv qhov piv txwv dhau los. Nrog rau qhov zoo li qub, qhov xav tau ΔT50 catalog ntsuam xyuas yuav yog kwv yees li 1,600 ÷ 0.51=3,137 W.
Cov no yog cov piv txwv qhov tseem ceeb, tsis yog SDEN tus qauv ntsuas. Kev suav qhia tias yog vim li cas cov haujlwm kub qis yuav xav tau lub tshuab hluav taws xob loj dua, ntau hom vaj huam sib luag lossis ntau dua ib qho emitter. Tau txais cov ntaub ntawv tso tawm rau cov qauv qhia tseeb ua ntej xaj.
3 Xaiv lub vaj huam sib luag hom thiab qhov ntev ua ke
Hlau vaj huam sib luag radiators siv dej nqa panels thiab, nyob rau hauv ntau designs, convector fins. Nyob rau hauv hom kev xaiv, thawj tus lej txheeb xyuas cov naj npawb ntawm cov panels thiab qhov thib ob txheeb xyuas cov naj npawb ntawm convector fin sets. Cov hauv qab no yog cov lus qhia kev tsim kho dav dav; muaj nyob ntawm tus neeg muag khoom qhov ntau.

Sib piv qhov siab, ntev, qhov tob thiab tso zis raws li ib qho kev qhia tshwj xeeb. Yog tias Hom 22 haum rau phab ntsa tab sis poob qis ntawm qhov ntsuas kub, xyuas seb hom 33 lossis chav tsev ntev dua tuaj yeem ua tau raws li qhov yuav tsum tau ua. Yog tias tsis haum, xav txog kev faib cov khoom nruab nrab ntawm ob lub radiators uas tsim nyog.
Peb kab rov tav steel vaj huam sib luag radiator ntau yam ntawm SDEN suav nrog Hom 22 thiab Hom 33 teeb tsa. Siv daim duab kos thiab tso tawm lub sijhawm rau qhov loj me thiab kev sib txuas lus tau hais. Ib hom naj npawb los ntawm nws tus kheej tsis yog qhov ntsuas kub tso zis.
4 Txheeb xyuas qhov chaw ua kom tiav
Ntsuas qhov chaw rau lub cev radiator, brackets, li qub thiab cov kav dej. Cia cov chaw tsim khoom yuav tsum tau tshem tawm saum toj, hauv qab thiab ib ncig ntawm lub tshuab hluav taws xob kom huab cua tuaj yeem ncig. Lub qhov rais sib sib zog nqus, radiator npog lossis lub rooj zaum loj tuaj yeem hloov qhov kev ua tau zoo txawm tias lub tshuab hluav taws xob haum rau lub cev.
Xyuas cov phab ntsa tsim thiab lub radiator qhov hnyav ua ntej xaiv fixings. Rau kev hloov, sau cov yeeb nkab chaw, kev sib txuas xov, inlet thiab qhov hluav taws xob txoj haujlwm thiab kev npaj valve. Lub tshuab hluav taws xob uas muaj qhov sib txawv sab nraud tseem yuav xav tau kev hloov pauv ntawm cov kav dej.
Xaiv cov kev sib txuas sab lossis hauv qab raws li daim duab pom zoo sib txuas. Paub meej tias cov brackets, cua vents, plugs, valve inserts thiab thermostat taub hau yog suav nrog los yog muab cais. Ib qho qauv ntsug yuav tsum tau kuaj xyuas siv nws tus kheej cov duab kos thiab cov ntaub ntawv ua haujlwm; tsis txhob tig tus qauv kab rov tav tshwj tsis yog nws cov chaw tsim khoom tau tso cai rau nws.
5 Txheeb xyuas cov kev txwv qhov system thiab cov kev cai kav ntev
Sib phim lub radiator qhov tso cai ua haujlwm siab thiab siab tshaj plaws kev khiav hauj lwm kub rau lub system tsim, nrog rau cov kev hloov siab hloov. Kev ntsuas siab yog ib qho kev txheeb xyuas cais thiab yuav tsum tsis txhob raug kho raws li qhov tso cai ua haujlwm tsis tu ncua. Hauv paus tsev kawm ntawv cov cua sov thiab kev txhim kho siab yuav tsum tau ua tib zoo saib xyuas lub tsev qhov tseeb hydraulic.
Txheeb xyuas cov txheej txheem npaj, kev kho dej thiab kev txwv glycol tiv thaiv cov lus qhia khoom. Rov qab cov dej tshiab saum toj saud thiab cov pa oxygen ingress tuaj yeem txhawb kev txhim kho sab hauv. Tshawb xyuas cov dej xau los yog qhov ua txhaum ntawm qhov system es tsis yog kho cov khoom siv rov ua kom zoo li qub.
Rau sab nrauv sab nrauv, nug txog pretreatment, txheej thiab npaj rau installation ib puag ncig. Ntawm SDEN, peb siv KTL electrophoretic txheej thiab hmoov tiav rau peb cov hlau vaj huam sib luag radiators. Thov cov lus qhia tshwj xeeb rau qhov kev xaiv, tshwj xeeb tshaj yog qhov muaj kev txhawj xeeb ntawm cov dej noo. Kev tiv thaiv kev tiv thaiv sab nrauv yuav tsum tsis txhob nyeem ua pov thawj tias txhua qhov dej sab hauv tau txais.
Lub thermostatic valve tuaj yeem tswj cov cua sov hauv chav, thiab lub taub hau ntse ntse tuaj yeem ntxiv sijhawm teem sijhawm lossis kev tswj chaw taws teeb. Ob leeg tseem nyob ntawm qhov raug qhov loj thiab commissioning. Lub installer yuav tsum yaug thiab ua haujlwm rau lub kaw lus raws li cov lus qhia uas siv tau, tso cua nkag, tshawb xyuas cov xau thiab sib npaug ntawm cov dej ntws ntawm cov radiators.
6 Sib piv cov khoom siv tag nrho
Nug cov neeg muag khoom los hais tawm rau tib lub hauv paus kev ua haujlwm: qauv, hom, qhov ntev, kev sib txuas kev sib txuas thiab cov khoom siv hluav taws xob ntawm qhov ntsuas kub. Thov kom siv tau cov khoom siv hluav taws xob los yog cov ntawv tshaj tawm, cov lus qhia kev teeb tsa thiab cov lus lav. Kev siv EN 442 yuav tsum muaj feem xyuam nrog cov ntaub ntawv cov khoom lag luam; ISO 9001 daim ntawv pov thawj kev tswj hwm zoo tsis yog qhov hloov pauv rau cov qauv ntsuas hluav taws xob pov thawj.
Rau ib qhov project lossis distributor xaj, kuj pom zoo qhov tiav, accessories, ntim, ntawv, kom muaj nuj nqis thiab xa khoom. Muab piv rau qhov ua tiav kom tus nqi qis dua tsis zais qhov sib txawv ntawm cov zis, ib qho kev tshem tawm valve teeb lossis kev teeb tsa ntxiv.
Npaj koj qhov kev nug rau SDEN
suav nrog qhov project qhov chaw thiab lub hom phiaj kev lag luam; chav tsev kub poob lossis lub sijhawm radiator; cov cua sov qhov chaw thiab tsim ntws, rov qab thiab chav tsev kub; muaj phab ntsa qhov ntev; ua haujlwm siab; kev txuas kos duab; thiab qhov ntau. Ntxiv cov khoom tiav, khoom siv, ntim lossis xa khoom yuav tsum tau ua.
Nrog rau cov ntsiab lus tsim, kev xaiv qauv dhau los ua qhov kev txiav txim siab: lub tshuab hluav taws xob xaiv yuav tsum ua kom tau raws li qhov ntsuas kub, haum rau kev teeb tsa thiab muaj cov ntaub ntawv txhawb nqa uas xav tau rau kev yuav khoom thiab commissioning.
