I-UNIVERSITY PARK, ePennsylvania - Iifestile eziphindwe kabini ezifakwe ngaphakathi kunye nomgangatho womoya okhuselayo unokubonelela ngokusebenza kwamandla amakhulu kuneefestile zepaneli enye, kodwa ukutshintshwa kweefestile ezikhoyo zepaneli enye kunokuba yindleko okanye kunzima umngeni.Olona khetho lunoqoqosho ngakumbi, kodwa lungasebenzi kakuhle kukugquma iifestile zegumbi elinye ngefilimu yentsimbi eguquguqukayo, efunxa ubushushu belanga ebusika ngaphandle kokuphazamisa ukucaca kweglasi.Ukuphucula ukusebenza kakuhle kokugquma, abaphandi basePennsylvania bathi i-nanotechnology inokunceda ukuzisa ukusebenza kwe-thermal ukuya kwinqanaba elineefestile eziphindwe kabini ebusika.
Iqela elivela kwiSebe lasePennsylvania lobuNjineli bezoBunjineli baPhanda ngeempawu zokonga amandla kwiingubo eziqukethe i-nanoscale components ezinciphisa ukulahleka kobushushu kunye nokufunxa ngcono ubushushu.Baphinde bagqibezela uhlalutyo lokuqala olubanzi lobuchule bamandla bezinto zokwakha.Abaphandi bapapashe iziphumo zabo kwi-Energy Conversion and Management.
Ngokutsho kukaJulian Wang, unjingalwazi onxulumene nobunjineli bokwakha, ukukhanya okukufutshane kwe-infrared - inxalenye yokukhanya kwelanga abantu abangenakuyibona kodwa banokuva ubushushu - inokusebenzisa umphumo oyingqayizivele we-photothermal ye-nanoparticles yesinyithi, ukwandisa ukuhamba kobushushu ngaphakathi.ngefestile.
"Sinomdla wokuqonda ukuba ezi ziphumo zinokuphucula njani amandla okusebenza kwezakhiwo, ngakumbi ebusika," utshilo uWang, osebenza kwiZiko lezoBugcisa kunye neZixhobo kwiSikolo sasePennsylvania soBugcisa kunye neArchitecture.
Iqela liqale laphuhlisa imodeli yokuqikelela ukuba bungakanani ubushushu obuvela ekukhanyeni belanga obunokubonakala, bufunxwe, okanye buhanjiswe ngeefestile ezigqunywe ngeenanoparticles zetsimbi.Bakhetha ikhompawundi ye-photothermal ngenxa yokukwazi ukufunxa imitha yelanga ekufutshane ne-infrared ngelixa isabonelela ngokuhanjiswa kokukhanya okubonakalayo okwaneleyo.Imodeli iqikelela ukuba i-coating ibonakalisa ukukhanya okungaphantsi kufutshane ne-infrared okanye ubushushu kwaye ifunxa ngakumbi ngefestile kunezinye iintlobo zeengubo.
Abaphandi bavavanya iifestile zeglasi ezifakwe kwi-nanoparticles phantsi kokukhanya kwelanga okufanisiweyo kwilebhu, eqinisekisa uqikelelo lokulinganisa.Iqondo lokushisa kwelinye icala lefestile ene-nanoparticle-coated liye landa kakhulu, libonisa ukuba i-coating inokufunxa ubushushu ukusuka ekukhanyeni kwelanga ukusuka ngaphakathi ukuhlawulela ukulahleka kobushushu bangaphakathi ngeefestile ezine-single-pane.
Abaphandi ke bondla idatha yabo kwimilinganiselo emikhulu ukuhlalutya ukonga amandla esakhiwo phantsi kweemeko ezahlukeneyo zemozulu.Xa kuthelekiswa nokukhanya okuphantsi kweefestile ezifumanekayo kurhwebo, iifestile ezifotayo zifunxa uninzi lokukhanya kwi-infrared spectrum, ngeli lixa iifestile ezigqunyiweyo ngokwesiko ziyibonisa ngaphandle.Oku kufunxa kufutshane ne-infrared kubangela ilahleko yobushushu engaphantsi kwe-12 ukuya kwi-20 yepesenti kunezinye iingubo, kwaye amandla okugcina amandla esakhiwo afikelela malunga neepesenti ezingama-20 xa kuthelekiswa nezakhiwo ezingagqunywanga kwiifestile ezinefestile enye.
Nangona kunjalo, uWang uthe ukuhanjiswa kwe-thermal engcono, inzuzo ebusika, iba yinto engafanelekanga kwixesha elifudumeleyo.Ukunika ingxelo ngotshintsho lwamaxesha onyaka, abaphandi baphinde bafaka ii-canopies kwiimodeli zabo zokwakha.Olu yilo luthintela ukukhanya okuthe ngqo kwelanga okufudumeza okusingqongileyo ehlotyeni, ubukhulu becala kuphelisa ukugqithiswa kobushushu obungalunganga kunye nazo naziphi na iindleko ezinxulumene nokupholisa.Iqela lisasebenza kwezinye iindlela, kuquka iinkqubo zefestile eziguquguqukayo ukuhlangabezana neemfuno zokufudumeza kwexesha kunye nokupholisa.
"Njengoko olu pho nonongo lubonisa, ngeli nqanaba lophononongo, sisenokuphucula ukusebenza kwe-thermal jikelele yeefestile ezine-glazed eyodwa ukuba zifane neefestile eziphindwe kabini ebusika," kusho uWang."Ezi ziphumo zicela umngeni kwizisombululo zethu zemveli zokusebenzisa iileya ezininzi okanye ukugquma ukubuyisela iifestile zegumbi elinye ukonga amandla."
"Ngenxa yemfuno enkulu kwisakhiwo sokwakhiwa kweziseko zamandla kunye nokusingqongileyo, kunyanzelekile ukuba siqhubele phambili ulwazi lwethu lokudala izakhiwo ezisebenza ngamandla," utshilo uSez Atamtürktur Russcher, uNjingalwazi uHarry kunye no-Arlene Schell kunye neNtloko yezoBunjineli boKwakha.“UGqr.UWang kunye neqela lakhe benza uphando olusisiseko. ”
Abanye abanegalelo kulo msebenzi baquka u-Enhe Zhang, umfundi ophumelele isidanga kuyilo lwezakhiwo;UQiuhua Duan, uNjingalwazi oNcedisayo woBunjineli boLuntu kwiYunivesithi yase-Alabama, wafumana i-PhD yakhe kwi-Architectural Engineering evela kwiYunivesithi yasePennsylvania State ngoDisemba 2021;U-Yuan Zhao, umphandi kwi-Advanced NanoTherapies Inc., oye waba negalelo kulo msebenzi njengomphandi we-PhD kwiYunivesithi yasePennsylvania State, uYangxiao Feng, umfundi we-PhD kuyilo lwezakhiwo.INational Science Foundation kunye neUSDA Natural Resources Conservation Service zawuxhasa lo msebenzi.
Izigqubuthelo zefestile (iimolekyuli ezisondeleleneyo) zibonakaliswe ukomeleza ukuhanjiswa kobushushu ukusuka ekukhanyeni kwelanga kwangaphandle (iintolo eziorenji) ukuya ngaphakathi kwesakhiwo ngeli lixa zisabonelela ngokuhanjiswa kokukhanya okwaneleyo (iintolo ezimthubi).Umthombo: Umfanekiso ngoncedo lukaJulian Wang.Onke Amalungelo Agciniwe.
