UNIVERSITY PARK, Pennsylvania - Mazenera owoneka bwino omwe ali ndi mpweya wotsekera amatha kupereka mphamvu zambiri kuposa mazenera amtundu umodzi, koma kusintha mazenera amtundu umodzi kumatha kukhala kokwera mtengo kapena kovuta mwaukadaulo.Njira yowonjezereka, koma yocheperapo ndiyo kuphimba mazenera a chipinda chimodzi ndi filimu yachitsulo yowoneka bwino, yomwe imatenga kutentha kwa dzuwa m'nyengo yozizira popanda kusokoneza kuwonekera kwa galasi.Pofuna kukonza bwino zokutira, ofufuza aku Pennsylvania ati nanotechnology ingathandize kupangitsa kuti kutentha kufanane ndi mazenera owala kawiri m'nyengo yozizira.
Gulu lochokera ku dipatimenti yoona za zomangamanga ku Pennsylvania linafufuza za zinthu zopulumutsa mphamvu za zokutira zomwe zili ndi zida za nanoscale zomwe zimachepetsa kutentha komanso kuyamwa bwino kutentha.Anamalizanso kusanthula kwatsatanetsatane kwamphamvu kwa zida zomangira.Ofufuzawa adasindikiza zomwe adapeza mu Energy Conversion and Management.
Malinga ndi Julian Wang, pulofesa wothandizana nawo wa zomangamanga, kuwala kwapafupi ndi infuraredi - mbali ya kuwala kwa dzuwa yomwe anthu sangakhoze kuwona koma amamva kutentha - ikhoza kuyambitsa mphamvu yapadera ya photothermal ya nanoparticles yachitsulo, kuonjezera kutentha kwa mkati.kudzera pawindo.
"Tili ndi chidwi chofuna kumvetsetsa momwe izi zingathandizire mphamvu zamagetsi zanyumba, makamaka m'nyengo yozizira," adatero Wang, yemwe amagwiranso ntchito ku Institute of Architecture and Materials ku Pennsylvania School of Art and Architecture.
Gululo lidayamba kupanga chitsanzo choyerekeza kuchuluka kwa kutentha kochokera ku kuwala kwa dzuwa komwe kungawonekere, kuyamwa, kapena kufalikira kudzera m'mazenera okutidwa ndi zitsulo za nanoparticles.Iwo anasankha photothermal compound chifukwa chakuti amatha kuyamwa kuwala kwa dzuwa komwe kumakhala pafupi ndi infrared pomwe amapereka kuwala kokwanira.Mtunduwu umaneneratu kuti zokutira zimawonetsa kuwala kocheperako pafupi ndi infrared kapena kutentha ndipo zimatengera zambiri kudzera pawindo kuposa zokutira zina zambiri.
Ofufuzawo adayesa mawindo agalasi limodzi lokhala ndi ma nanoparticles pansi pa kuwala kwa dzuwa mu labu, kutsimikizira kulosera koyerekeza.Kutentha kwa mbali imodzi ya zenera lokhala ndi nanoparticle kunakula kwambiri, kutanthauza kuti chophimbacho chimatha kuyamwa kutentha kuchokera ku kuwala kwa dzuwa kuchokera mkati kuti chiteteze kutentha kwa mkati mwa mawindo amtundu umodzi.
Ochita kafukufukuwo adadyetsa deta yawo m'mayesero akuluakulu kuti afufuze momwe nyumbayi imasungiramo mphamvu pa nyengo zosiyanasiyana.Poyerekeza ndi zokutira zotsika zotulutsa mpweya za mawindo amodzi omwe amapezeka pamalonda, zokutira za Photothermal zimatenga kuwala kozungulira pafupi ndi infrared sipekitiramu, pomwe mazenera okutidwa kale amawawonetsa kunja.Mayamwidwe amtundu wa infraredwa amapangitsa kuti kutentha kuchepe pang'ono ndi 12 mpaka 20 peresenti poyerekeza ndi zokutira zina, ndipo mphamvu yopulumutsa mphamvu ya nyumbayo imafika pafupifupi 20 peresenti poyerekeza ndi nyumba zosakutidwa pamawindo amtundu umodzi.
Komabe, Wang adanena kuti kutentha kwabwinoko, mwayi m'nyengo yozizira, kumakhala kovuta m'nyengo yofunda.Kuti afotokoze za kusintha kwa nyengo, ofufuzawo adaphatikizanso ma canopies muzomanga zawo.Kapangidwe kameneka kamalepheretsa kuwala kwa dzuwa komwe kumatenthetsa chilengedwe m'chilimwe, makamaka kuchotsa kutentha kosasunthika ndi kuzizira kulikonse.Gululi likugwiritsabe ntchito njira zina, kuphatikizapo mawindo amphamvu kuti akwaniritse kutentha kwa nyengo ndi kuzizira.
"Monga momwe phunziroli likusonyezera, pa nthawi ino ya phunziroli, tikhozabe kupititsa patsogolo kutentha kwa mazenera amtundu umodzi kuti akhale ofanana ndi mazenera owoneka kawiri m'nyengo yozizira," adatero Wang."Zotsatirazi zimatsutsa njira zathu zachikhalidwe zogwiritsira ntchito zigawo zambiri kapena kusungunula kukonzanso mawindo a chipinda chimodzi kuti tisunge mphamvu."
"Poganizira za kufunikira kwakukulu kwa nyumba zopangira mphamvu zamagetsi komanso chilengedwe, ndikofunikira kuti tipititse patsogolo chidziwitso chathu kuti tipange nyumba zogwiritsa ntchito mphamvu," adatero Sez Atamtürktur Russcher, Pulofesa Harry ndi Arlene Schell ndi Mtsogoleri wa Zomangamanga.“Dr.Wang ndi gulu lake akuchita kafukufuku wofunikira. ”

Zophimba mazenera (mamolekyu oyandikira) awonetsedwa kuti amathandizira kutentha kwa dzuwa kuchokera ku kuwala kwa dzuwa (mivi ya lalanje) kupita mkatikati mwa nyumba pomwe amapereka kuwala kokwanira (mivi yachikasu).Source: Chithunzi mwachilolezo cha Julian Wang.Maumwini onse ndi otetezedwa.
