UNIVERSITY PARK, Pennsylvania - Mahwindo akapetwa kaviri akaiswa mukati nemhepo inodzivirira anogona kupa simba rakakura kupfuura mahwindo epane imwe chete, asi kutsiva mahwindo epane imwe chete aripo anogona kudhura kana kunetsa.Imwe nzira yehupfumi, asi isingashande ndeyekuvhara mahwindo ekamuri imwe chete nefirimu yesimbi inopenya, inotora kumwe kupisa kwezuva munguva yechando pasina kukanganisa kujeka kwegirazi.Kuti uvandudze kunyatsoita zvekupfeka, vaongorori vePennsylvania vanoti nanotechnology inogona kubatsira kuunza mashandiro ekupisa kusvika padanho nemahwindo akapenya kaviri munguva yechando.
Chikwata chinobva kuPennsylvania Department of Architectural Engineering chakaongorora zvinhu zvinochengetedza simba zvemajasi ane nanoscale components zvinoderedza kurasikirwa nekupisa uye zvirinani kutora kupisa.Vakapedzawo yekutanga ongororo yakazara yesimba rekushandisa kwezvinhu zvekuvaka.Vatsvagiri vakaburitsa zvavakawana muEnergy Shanduko uye Management.
Maererano naJulian Wang, purofesa anoshamwaridzana weinjiniya yekuvaka, pedyo-infrared chiedza - chikamu chechiedza chezuva icho vanhu vasingagoni kuona asi vanogona kunzwa kupisa - chinogona kumisa iyo yakasarudzika photothermal mhedzisiro yeimwe simbi nanoparticles, kuwedzera kupisa kuyerera mukati.nepahwindo.
"Tinofarira kunzwisisa kuti izvi zvinokonzeresa zvinogona sei kuvandudza kushanda kwesimba kwezvivakwa, kunyanya munguva yechando," akadaro Wang, anoshandawo kuInstitute of Architecture and Materials paPennsylvania School of Art and Architecture.
Chikwata chakatanga kugadzira modhi yekufungidzira kuti ingani kupisa kwezuva kwaizoratidzwa, kunyudzwa, kana kufambiswa nemahwindo akavharwa nesimbi nanoparticles.Vakasarudza photothermal compound nekuda kwekukwanisa kwayo kutora chiedza chezuva chiri pedyo-infrared ichiri kupa chiedza chakakwana chekufambisa.Iyo modhi inofanotaura kuti iyo coating inoratidza kushoma padyo nechiedza che infrared kana kupisa uye inotora zvakawanda nepahwindo kupfuura mamwe marudzi mazhinji emajasi.
Vatsvagiri vakaedza magirazi egirazi mahwindo akavharwa nenanoparticles pasi pechiedza chezuva murabhoritari, achisimbisa fungidziro yekufungidzira.Tembiricha kune rimwe divi rewindo rakavharwa nenanoparticle yakawedzera zvakanyanya, zvichiratidza kuti iyo yekupfeka inogona kutora kupisa kubva kuchiedza chezuva kubva mukati kuti idzorere kurasikirwa kwekupisa kwemukati kuburikidza nemahwindo epane imwe chete.
Vatsvakurudzi vakabva vadyisa data yavo mukuenzanisa kukuru kuti vaongorore kuchengetedza kwesimba kwechivako pasi pemamiriro ekunze akasiyana-siyana.Zvichienzaniswa neakadzika emisisivity coatings yemahwindo ekutengesa anowanikwa ekutengesa, photothermal coatings inotora yakawanda yechiedza chiri pedyo-infrared spectrum, nepo mahwindo akavharidzirwa anoratidza kunze.Kunyura kuri pedyo-kwe-infrared uku kunoguma nekurasikirwa nekupisa kuderera pane mamwe mabhanhire, uye simba rekuchengetedza simba rechivako rinosvika 20 muzana zvichienzaniswa nezvivakwa zvisina kuvharwa pamahwindo epane imwe chete.
Nekudaro, Wang akataura kuti zvirinani kupisa conductivity, mukana muchando, inova kukanganisa mumwaka unodziya.Kuzvidavirira nezvekuchinja kwemwaka, vaongorori vakaisawo canopies mumhando dzavo dzekuvaka.Iyi dhizaini inovhara zuva rakananga rinopisa nharaunda muchirimo, zvakanyanya kubvisa kushomeka kwekutamisa kupisa uye chero mari inosanganisirwa yekutonhodza.Chikwata chichiri kushanda pane dzimwe nzira, kusanganisira dynamic windows masisitimu ekusangana nemwaka kudziyisa uye kutonhora zvinodiwa.
"Sezvo chidzidzo ichi chinoratidza, panguva ino yekudzidza, tinogona kuvandudza kushanda kwese kwekushisa kwemahwindo e-single-glazed kufanana nemahwindo maviri-glazed munguva yechando," akadaro Wang."Izvi mhedzisiro zvinopokana nemhinduro dzedu dzechinyakare dzekushandisa mamwe matinji kana insulation kudzoreredza mahwindo ekamuri imwe chete kuchengetedza simba."
"Tichifunga nezvekudiwa kukuru kwezvivakwa zvesimba remagetsi pamwe nezvakatipoteredza, zvakakosha kuti tifambise ruzivo rwedu kugadzira zvivakwa zvinoshandisa simba," akadaro Sez Atamtürktur Russcher, Muzvinafundo Harry naArlene Schell uye Musoro weInjiniya Yekuvaka.“Dr.Wang nechikwata chake vari kuita tsvakiridzo yakakosha.
