Upende wemoto omusha ungangena esikhundleni se-air conditioning

Upende omusha owenziwe ososayensi ungenza ingaphakathi lemoto lipholile ngisho nalapho ubhekene namazinga okushisa aphezulu. Upende oshiwo ungasetshenziswa ezakhiweni noma ezindlini.

Ukungayidingi imoto, ngisho noma izinga lokushisa elingu-100-degree, kungaba umqondo omuhle, futhi nakuba kuzwakala kungenakwenzeka, kungaba ngokoqobo. Ifomula entsha kapende esanda kwakhiwa ingasiza ekwenzeni izakhiwo nezimoto zinganciki kakhulu kuma-air conditioner..

Onjiniyela baseNyuvesi yasePurdue benze upende oguquguqukayo. Lona umhlophe kakhulu owake wenziwa. Manje, abacwaningi bathi ukufaka lo pende ezimotweni noma ezakhiweni kunciphisa isidingo se-air conditioning.

Ifomula kapende omhlophe kakhulu igcina noma yini ependwe ngokupholile kakhulu

Ifomula kapende omhlophe kakhulu we-Purdue igcina yonke into ipendwe iyintsha. "Uma ubungasebenzisa lo pende ophahleni olumboze cishe amamitha-skwele angu-1,000, silinganisela ukuthi ungathola amandla okupholisa ama-kilowatt angu-10," u-Xiuling Ruan, uprofesa wobunjiniyela bemishini e-Purdue, etshela i-Scitechdaily. “Lokhu kunamandla ukwedlula ama-air conditioner amaphakathi asetshenziswa ezindlini eziningi,” esho.

Cishe uyayikhumbula i-Vantablack, lowopende omnyama omunca u-99% wokukhanya okubonakalayo. Hhayi-ke, lopende omhlophe omhlophe uphambene ncamashi neVantablack. Okusho ukuthi, kukhombisa u-98.1% wemisebe yelanga.

Kuthathe iminyaka eyisithupha yocwaningo ukuthola upende omhlophe kakhulu. Empeleni, isuka ocwaningweni olwenziwa ngeminyaka yawo-1970.. Ngaleso sikhathi, ucwaningo lwaluqhubeka lokwakha upende wokupholisa ngemisebe.

Isebenza kanjani?

Ukushisa kwe-infrared kuphuma kuyo yonke into ependwe mhlophe. Lokhu kuphambene ngokuphelele nokusabela kopende omhlophe ojwayelekile. Iba nokufudumala esikhundleni sokubanda ngaphandle uma iklanyelwe ukuqeda ukushisa.

Lo pende omhlophe owakhelwe ngokukhethekile ubonisa kuphela u-80-90% wokukhanya kwelanga. Futhi ayipholisi indawo edwetshwe kuyo. Lokhu kusho nokuthi akupholi okuzungeza lolu hlobo lukapende.

Pho yini eyenza lo mlungu omhlophe ube mhlophe ngendlela exakile? I-barium sulfate eyandisa izakhiwo zayo zokupholisa. I-Barium sulfate iphinde isetshenziswe ekukhiqizeni iphepha lezithombe, futhi yilokho okwenza ezinye izimonyo zibe mhlophe.

Ukusebenzisa i-barium sulfate kwenza izinto zibonakale kakhudlwana

"Sibheke imikhiqizo ehlukahlukene yokuhweba, ngokuyisisekelo noma yini emhlophe," kusho u-Xiangyu Li, Ph.D. e-Purdue. umfundi elabhorethri Rouen sika. “Sithole ukuthi ngokusebenzisa i-barium sulfate, ungenza izinto zibonakale kakhulu. Lokhu kusho ukuthi bamhlophe kakhulu,” usho kanje.

Esinye isizathu esenza ukuthi upende omhlophe ubonakale kakhulu kungenxa yokuthi izinhlayiya ze-barium sulfate zinobukhulu obuhlukene. Izinhlayiya ezinkulu ze-barium sulfate zisakaza ukukhanya kangcono. Ngakho-ke, osayizi bezinhlayiyana abahlukene basiza ekuhlakazeni okwengeziwe ukukhanya kwelanga.

Ukuhlangana kwezinhlayiya kupende kuyindlela engcono kakhulu yokwenza okumhlophe kubonakale. Kodwa okubi ukuthi ukugxila okuphezulu kwezinhlayiya kwenza kube lula ukuxebula upende. Ngakho-ke, ngokombono ongokoqobo, ukuba ngopende omhlophe akukuhle kakhulu.

Upende utholakale upholisa izindawo ezipendiwe. Ebusuku, upende ugcina indawo epholile engu-19 degrees ngaphezu kwanoma yini enye ezungeze into ependiwe. Ezimweni zokushisa okukhulu, ipholisa ubuso obungaphansi ngamadigri angu-8 kunezinto ezizungezile.

Siyazibuza ukuthi izinga lokushisa eliphansi kangakanani lingancishiswa ngokuhlolwa okwengeziwe. Uma lokhu kuhlolwa ngopende omhlophe kungehlisa izinga lokushisa nangokwengeziwe, isipholile singase siphelelwe yisikhathi. Noma okungenani unciphise isidingo sokuvula umoya emotweni noma ekhaya.
