Ntau tus neeg hauv kev lag luam photovoltaic lossis cov phooj ywg uas paub txog kev tsim hluav taws xob photovoltaic paub tias kev nqis peev hauv kev teeb tsa photovoltaic fais fab nroj tsuag ntawm lub ru tsev ntawm cov tsev nyob lossis cov chaw lag luam thiab cov chaw lag luam tuaj yeem tsis tsuas yog tsim hluav taws xob thiab ua kom tau nyiaj, tab sis kuj muaj cov nyiaj tau los zoo.Nyob rau lub caij ntuj sov, nws tseem tuaj yeem txo qhov kub thiab txias ntawm cov tsev.Cov nyhuv ntawm rwb thaiv tsev kub thiab txias.
Raws li kev ntsuam xyuas ntawm cov koom haum tshaj lij, qhov ntsuas kub hauv tsev ntawm cov tuam tsev nrog photovoltaic fais fab nroj tsuag tau nruab rau ntawm lub ru tsev yog 4-6 degrees qis dua cov tsev tsis muaj kev teeb tsa.
Lub ru tsev-mounted photovoltaic fais fab nroj tsuag puas tuaj yeem txo qhov kub hauv tsev los ntawm 4-6 degrees?Niaj hnub no, peb yuav qhia koj cov lus teb nrog peb pawg ntawm cov ntaub ntawv sib piv ntsuas.Tom qab nyeem nws, koj yuav muaj kev nkag siab tshiab ntawm cov nyhuv txias ntawm photovoltaic fais fab nroj tsuag.
Ua ntej tshaj plaws, xyuas seb qhov chaw nres tsheb photovoltaic tuaj yeem txias lub tsev li cas:
Ua ntej ntawm tag nrho cov, photovoltaic modules yuav muaj kev cuam tshuam cua sov, tshav ntuj illuminates photovoltaic modules, photovoltaic modules nqus ib feem ntawm lub hnub ci zog thiab hloov mus rau hauv hluav taws xob, thiab lwm qhov ntawm lub hnub ci yog reflected los ntawm photovoltaic modules.
Qhov thib ob, lub photovoltaic module refracts lub hnub ci projected, thiab lub hnub ci yuav attenuated tom qab lub refraction, uas zoo lim lub hnub ci.
Thaum kawg, photovoltaic module tsim ib lub tsev nyob rau ntawm lub ru tsev, thiab photovoltaic module tuaj yeem tsim ib qho chaw ntxoov ntxoo rau ntawm lub ru tsev, uas ntxiv cov nyhuv ntawm thermal rwb thaiv tsev thiab cua txias ntawm lub ru tsev.
Tom ntej no, sib piv cov ntaub ntawv ntawm peb txoj haujlwm ntsuas kom pom qhov txias npaum li cas ntawm lub ru tsev-mounted photovoltaic fais fab chaw nres tsheb tuaj yeem txias.
1. National-theem Datong Economic thiab Technological Development Zone Investment Promotion Center Atrium Lighting Roof Project
Ntau tshaj 200 square metres ru tsev ntawm atrium ntawm Kev nqis peev txhawb nqa ntawm National Datong Economic thiab Technological Development Zone yog Ameslikas ua los ntawm cov iav tempered zoo tib yam teeb pom kev zoo ru tsev, uas muaj qhov zoo ntawm kev zoo nkauj thiab pob tshab, raws li pom hauv daim duab hauv qab no. :
Txawm li cas los xij, lub ru tsev teeb pom kev zoo no yog kev ntxhov siab heev thaum lub caij ntuj sov, thiab nws tsis tuaj yeem ua tiav cov txiaj ntsig ntawm kev rwb thaiv tsev kub.Thaum lub caij ntuj sov, lub hnub ci ntsa iab nkag rau hauv chav los ntawm lub ru tsev iav, thiab nws yuav kub heev.Ntau lub tsev uas muaj iav ru tsev muaj teeb meem zoo li no.
Yuav kom ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab cua txias, thiab tib lub sijhawm ua kom zoo nkauj thiab lub teeb xa hluav taws xob ntawm lub tsev ru tsev, tus tswv thaum kawg xaiv photovoltaic modules thiab nruab rau ntawm lub ru tsev iav qub.
Lub installer tab tom txhim kho photovoltaic modules ntawm lub ru tsev
Tom qab kev teeb tsa photovoltaic modules ntawm lub ru tsev, qhov ua kom txias yog dab tsi?Ua tib zoo saib xyuas qhov ntsuas kub los ntawm cov neeg ua haujlwm tsim kho ntawm tib qhov chaw ntawm qhov chaw ua ntej thiab tom qab kev teeb tsa:
Nws tuaj yeem pom tau tias tom qab kev teeb tsa ntawm lub chaw nres tsheb photovoltaic, qhov kub ntawm sab hauv ntawm lub khob poob qis dua 20 degrees, thiab qhov kub hauv tsev kuj tseem poob qis, uas tsis tsuas yog txuag tau nyiaj hluav taws xob zoo heev ntawm kev xa cov hluav taws xob. cua txias, tab sis kuj ua tiav cov txiaj ntsig ntawm kev txuag hluav taws xob thiab cua txias, thiab cov photovoltaic modules ntawm lub ru tsev tseem yuav nqus lub hnub ci zog.Lub zog tsis tu ncua hloov mus rau hauv hluav taws xob ntsuab, thiab qhov zoo ntawm kev txuag hluav taws xob thiab kev khwv nyiaj yog qhov tseem ceeb heev.
2. Photovoltaic pobzeb project
Tom qab nyeem cov nyhuv txias ntawm photovoltaic modules, cia peb saib lwm yam tseem ceeb ntawm cov khoom siv hluav taws xob photovoltaic lub tsev - yuav ua li cas txias ntawm cov vuas photovoltaic?
Hauv kev xaus:
1) Qhov kub ntawm qhov sib txawv ntawm pem hauv ntej thiab nraub qaum ntawm cov pobzeb cement yog 0.9 ° C;
2) Qhov kub sib txawv ntawm lub hauv ntej thiab sab nraum qab ntawm cov pobzeb photovoltaic yog 25.5 ° C;
3) Txawm hais tias cov pobzeb photovoltaic absorbs tshav kub, qhov kub ntawm qhov saum npoo yog siab dua li ntawm cov pobzeb cement, tab sis qhov kub ntawm sab nraub qaum yog qis dua li cov pobzeb cement.Nws yog 9 ° C txias dua li cov vuas cement.
(Special Note: Infrared Thermometers yog siv rau hauv cov ntaub ntawv sau tseg no. Vim yog xim ntawm qhov chaw ntawm cov khoom ntsuas, qhov kub thiab txias yuav txawv me ntsis, tab sis nws yeej qhia txog qhov kub thiab txias ntawm tag nrho cov khoom ntsuas thiab tuaj yeem siv los ua ib qho siv.)
Nyob rau hauv qhov kub ntawm 40 ° C, thaum 12 tav su, lub ru tsev kub yog siab li 68.5 ° C.Qhov kub ntsuas ntawm qhov chaw ntawm lub photovoltaic module tsuas yog 57.5 ° C, uas yog 11 ° C qis dua lub ru tsev kub.PV module qhov kub ntawm lub nraub qaum yog 63 ° C, uas tseem yog 5.5 ° C qis dua lub ru tsev kub.Nyob rau hauv lub photovoltaic modules, qhov kub ntawm lub ru tsev yam tsis muaj lub hnub ci ncaj qha yog 48 ° C, uas yog 20.5 ° C qis dua li ntawm lub ru tsev unshielded, uas zoo ib yam li qhov kub thiab txias tau kuaj pom los ntawm thawj qhov project.
Los ntawm cov kev ntsuam xyuas ntawm peb lub tuam txhab photovoltaic saum toj no, nws tuaj yeem pom tau tias cov thermal rwb thaiv tsev, cua txias, txuag hluav taws xob thiab emission txo qhov cuam tshuam ntawm kev txhim kho photovoltaic fais fab nroj tsuag ntawm lub ru tsev yog qhov tseem ceeb, thiab tsis txhob hnov qab tias muaj 25- xyoo zog tsim cov nyiaj tau los.
Qhov no kuj yog qhov laj thawj tseem ceeb vim li cas ntau thiab ntau cov tswv lag luam thiab cov tswv lag luam thiab cov neeg nyob hauv xaiv los nqis peev hauv kev teeb tsa ntawm photovoltaic fais fab nroj tsuag ntawm lub ru tsev.
