Vacuum girazi

Tsanangudzo Pfupi

Vacuum girazi rudzi rutsva rwegirazi rinochengetedza simba.Inoumbwa nemagirazi maviri kana kupfuura.Magirazi egirazi anoparadzaniswa nerutsigiro nehupamhi hwe 0.2mm mune array array.Iwo maviri magirazi magirazi akavharwa ane yakaderera melting point solder akaapoteredza.Zvadaro, chimedu chegirazi chimwe chinosara chine chiteshi chekudhonza mhepo, uye mushure mekubuda kwevacuum, chinonamwa nepepa rekuvharisa uye solder yepasi-tembiricha kuti iite vacuum cavity.Zvigadzirwa zvikuru ndeye tempered vacuum girazi, hollow composite vacuum girazi uye laminated composite vacuum girazi.Inoshandiswa zvakanyanya mukuvaka, magonhi nemahwindo emotokari uye zvikepe, midziyo yemumba, aerospace uye girazi simba rekugadzira. Iyo yakakwirira-vacuum yemukati mhango yevacuum girazi inovhara zvinobudirira kuchinjisa kupisa, uye kupisa kwayo kupisa kwekuita ndeye 2-4 nguva iyo ye insulating girazi uye 6-10 nguva iyo yegirazi monolithic.
Kuita kwayo kunogona kusangana nezvinodiwa zvepasi rose passive imba yekupisa kupisa coefficient yemagonhi nemahwindo.

Process nzira

Iyo kambani inotora inotungamira pasi rose "danho-rimwe" kugadzira ine anopfuura makumi matanhatu patents.Iyo yepakutanga firimu ichashandisa yakajairika girazi, girazi rinodziya kana semi-hasha girazi.Shandisa girazi rakadzikama kana girazi rakadzika-e kuti uise iyo yakaderera-e firimu mukati memukati wevacuum layer kuti uvandudze mashandiro emafuta, uye batanidza girazi rekutsvaira nechimwe chidimbu kana zvidimbu zviviri zvegirazi kuburikidza neyakaumbwa girazi kana laminated girazi kuti uite composite vacuum Girazi yekuvandudza kuchengeteka.

Zvitanhatu zvakanakira

Thermal insulation

Iyo vacuum layer yevacuum girazi inogona kusvika 10 ^(-2) pa, iyo inodzivirira zvinobudirira kupisa conduction.

Inzwi rekudzivirira uye kuderedza ruzha

Iyo vacuum layer yevacuum girazi inogona kunyatso kuvharira kutapurirana kwekurira.Iyo inoremerwa inonzwika yekuvharisa yegirazi imwe chete yekuvhaira inogona kusvika 37 decibel, uye yakanyanya ruzha insulation yecomposite vacuum glass inogona kusvika 42 decibels, zviri nani kupfuura insulating glass.

Anti-condensation

Kana hunyoro huri 65% uye tembiricha yemukati i20°C, tembiricha yevacuum yegirazi iri pasi pe-35°C kunze, ukuwo tembiricha yekudziya yeLOW-E insulating glass inenge -5°C kunze.

Chiedza uye chimiro chakaonda

Girazi mhando	Girazi chimiro	U valueW/ (㎡·k)	thicknessmm	uremu (kg/㎡)
Vacuum girazi	TL5+V+T5	≈0.6	10	25
Girazi regomba (Yakazadzwa neinert gasi)	TL5+16Ar+T5+16A r+TL5	≈0.8	45	28

Cherechedza: Kuwanda kwegirazi ndiko 2500kg/m3.Kurema kuverenga kunongotarisa huremu hwegirazi, kusazvidza huremu hwezvishandiso.

Vacuum girazi rinongoda zvidimbu zviviri zvegirazi kuti usvike pamutengo wakaderera weU, senge 0.58W/(㎡.k).Insulating glass inoda kushandisa magirazi matatu nema cavities maviri, 2-3 zvidimbu zveLow-E glass, uye izere neinert gas.Inogona kusvika 0.8W/(㎡.k).

Beijing Tianheng Building

Chivako chekutanga chehofisi chepasi rose chine vacuum glass curtain wall

Yakavakwa muna 2005 uye inotora T6 + 12A + L5 + V + N5 + 12A + T6 chimiro, uye kukosha kweU kunogona kusvika 1.2W / ㎡k.Chiyero chepamusoro-soro chepasi rose chekuvhara hwindo ndeye 10, uye inzwi rekudzivirira. inosvika ma<em>decibel 37, ichichengetedza mabhiri emagetsi anopfuura miriyoni imwe gore negore.

Qinhuangdao "padivi pemvura" pekugara pamba

China yekutanga passive house project kupihwa certified neGerman Energy Agency

Yakapedzwa muna 2013. Semi-tempered vacuum girazi yakashandiswa pamagonhi nemahwindo epurojekiti, uye kukosha kweU kwakanga kuri pasi pe0.6 W/㎡k.

Changsha Riverside Cultural Park

Nzvimbo yekutanga yekugadzira girazi revacuum pasi rose

Yakapedzwa muna 2011, inoumbwa nezvivakwa zvitatu zvine mabasa akasiyana: Bhuku Chiedza, Bo Wuguang uye Concert Hall.Kushandiswa kwegirazi revacuum kunodarika 12,000 square metres, uye saizi yakakura inodarika 3.5x1.5m.

Zhengzhou Library

National Demonstration Unit yeKuvaka Energy Efficiency Library

Yakapedzwa muna 2011, ichishandisa 10,000㎡ vacuum girazi keteni madziro uye masikati machena denga.Zvinofungidzirwa kuti kana zvichienzaniswa nekushandiswa kwegirazi rinodzivirira, rinogona kuchengetedza 430,000 kilowatt-maawa emagetsi uye inoda kusvika 300,000 yuan pagore.

Iyo inoremerwa inonzwika yekuvharisa yevacuum girazi inosvika makumi mana nemaviri decibel, ichigadzira yakanyarara uye yakasununguka nzvimbo yekuverenga yevaverengi.
