Pendi itsva yemota inogona kutsiva air conditioning

Pendi itsva yakagadziridzwa nemasayendisiti inogona kuita kuti mukati memotokari itonhorese kunyange kana paine tembiricha yepamusoro. Yakati pendi inogonawo kushandiswa pazvivakwa kana dzimba.

Kusamboda mota, kunyangwe iri 100-degree kupisa, ingave pfungwa huru, uye kunyangwe ichinzwika sechisingagoneki, chinogona kuve chokwadi. Ichangobva kugadzirwa fomula nyowani yependi inogona kubatsira kuita kuti zvivakwa nemota zvisanyanya kutsamira pamaair conditioner..

Purdue University mainjiniya vakagadzira pendi yekuchinja. Uyu ndiwo muchena wakacheneruka wati waitwa. Ikozvino, vaongorori vanoti kuisa pendi iyi kumotokari kana zvivakwa kunoderedza kudiwa kwemhepo inofefetera.

Ultra-chena pendi fomula inochengeta chero chayakapendwa pane inotonhorera zvakanyanya

Purdue's Ultra-white pendi formula inochengeta zvese zvakapendwa zviri nyowani. "Dai iwe waizoshandisa pendi iyi padenga rinovhara makiromita 1,000 masikweya, tinofungidzira kuti unogona kuwana gumi kilowatts yekutonhodza," Xiuling Ruan, purofesa wemechanichani paPurdue, akaudza Scitechdaily. "Izvi zvine simba kupfuura epakati air conditioners anoshandiswa mudzimba zhinji," akadaro.

Iwe unogona kunge uchiyeuka Vantablack, iyo pendi nhema inotora 99% yechiedza chinooneka. Zvakanaka, iyi chena chena pendi ndiyo yakanyatsopesana neVantablack. Kureva kuti inoratidza 98.1% yemwaranzi yezuva.

Zvakatora makore matanhatu ekutsvaga kutsvaga pendi chena chena. Chokwadi, kunobva mukutsvagisa kwakaitwa kuma1970s.. Panguva iyoyo, tsvakiridzo yakanga ichiitwa kugadzira pendi yekutonhodza yeradioactive.

Sei kushanda?

Infrared heat inobuda kubva kune zvese zvakapendwa zvichena. Izvi zvinopesana zvakakwana nezvinoitwa nependi chena. Inotanga kudziya, kwete kutonhora, kunze kwekunge yakanyatsogadzirirwa kubvisa kupisa.

Iyi pendi chena yakanyatsogadzirwa inongoratidza 80-90% yechiedza chezuva. Uye haitonhodze nzvimbo yayakadhonzwa. Izvi zvinoreva zvakare kuti haitonhodze izvo zvakatenderedza rudzi urwu rwepende.

Saka chii chinoita kuti uku kuchena kwakanyanya kuve chena zvisingaite? Iyo barium sulfate inowedzera kutonhora kwayo. Barium sulfate inoshandiswawo mukugadzirwa kwepepa remifananidzo, uye ndiyo inoita kuti zvimwe zvizorwa zvichena.

Kushandisa barium sulfate kunoita kuti zvinhu zviratidzike

"Takatarisa zvakasiyana siyana zvekutengesa zvigadzirwa, chero chinhu chichena," akadaro Xiangyu Li, Ph.D. kuPurdue. mudzidzi murabhoritari yeRouen. "Takaona kuti nekushandisa barium sulfate, unogona kuita kuti zvinhu zviratidzike zvakanyanya. Kureva kuti vachena chose,” vakadaro.

Chimwe chikonzero nei pendi chena ichiratidzira zvakanyanya imhaka yekuti barium sulfate particles ane hukuru hwakasiyana. Zvimedu zvakakura zvebarium sulfate zvinoparadzira chiedza zviri nani. Naizvozvo, masaizi akasiyana-siyana anobatsira kuwedzera kuparadzira mwenje wezuva.

Iko kusangana kwezvimedu mupende ndiyo nzira yakanakisa yekuita chena kuti iratidze. Asi chakashata ndechekuti kuwanda kwezvimedu kunoita kuti zvive nyore kubvisa pendi. Saka, kubva pakuona kunoshanda, kuve pendi chena haina kunyanya kunaka.

Pendi yakawanikwa inotonhodza nzvimbo dzakapendwa. Husiku, pendi inochengeta nzvimbo inotonhorera madhigirii 19 kupfuura chero chinhu chakatenderedza chinhu chakapendwa. Mumamiriro ekupisa kwakanyanya, inotonhorera pasi 8 degrees yakaderera pane zvinhu zvakapoteredza.

Isu tinoshamisika kuti ingani tembiricha yakaderera inogona kudzikiswa nekuedza kwakawanda. Kana izvi zviedzo nependi chena zvichigona kudzikisa tembiricha zvakatonyanya, air conditioner inogona kupera basa. Kana kuti zvishoma kuderedza kukosha kwekuvhura mhepo mumotokari kana kumba.
