Poyerekeza ndi galasi loteteza kutentha,galasi loteteza utsiIli ndi mphamvu yabwino kwambiri yotetezera kutentha. Kutentha kumasamutsidwa m'njira zitatu: kuyendetsa, kuwala, ndi kutsekeka kwa magetsi. Pakati pawo, kuyendetsa kutentha kuyenera kudutsa mu sing'anga, ndipo zitha kuganiziridwa kuti palibe sing'anga mu vacuum wosanjikiza, kotero kuti kuyendetsa kutentha kuchepe. Galasi lotetezedwa ndi vacuum limangoyendetsa kutentha m'mphepete, ndipo gawo lake lalikulu limakhala lotetezedwa kwathunthu. Mtengo wa Ug wosinthira kutentha wa galasi lotetezedwa ndi vacuum ukhoza kupezeka mosavuta pansi pa 0.5W/㎡, pomwe Ug wosinthira kutentha wa galasi lotetezedwa ndi magalasi atatu umafika pa 0.7W/㎡K, yomwe ili pafupi ndi malire. Chifukwa cha magwiridwe antchito abwino kwambiri otetezera kutentha a galasi lotetezedwa ndi vacuum, m'madera ozizira kwambiri, ngakhale kutentha kochepa kwambiri panja m'nyengo yozizira, kutentha kwa mkati mwa galasi kumatha kusungidwabe pamwamba pa kutentha kwa dem point, motero kuletsa kuzizira.
Galasi loteteza ku zinyalalaIli ndi mphamvu yabwino yotumizira kuwala. Pofuna kuchepetsa kutentha kwa galasi, galasi loteteza kutentha ndi losunga mphamvu lomwe limagwiritsidwa ntchito m'nyumba ndi galasi la Low-E, lomwe limadziwikanso kuti galasi lopanda kutulutsa mphamvu zambiri. Pamwamba pa galasilo pali filimu ya Low-E, yomwe ndi filimu yopangidwa ndi zitsulo kapena zinthu zina zambiri, zomwe zimatha kuwonetsa kuwala kwa infrared, motero zimachepetsa kutentha kwa mkati mwa radiation m'nyengo yozizira. Koma pali zabwino ndi zoyipa.
Filimu ya Low-E siimangowonetsa kuwala kwa infrared, komanso imawonetsa kuwala kooneka, zomwe zimapangitsa kuti galasi lizigwira ntchito bwino kwambiri popereka kuwala. Kuti likhale ndi mphamvu yoteteza kutentha, galasi loteteza kutentha la magalasi atatu nthawi zambiri limagwiritsa ntchito kapangidwe ka Low-E kawiri, zomwe zimapangitsa kuti mphamvu yotumizira kuwala yooneka τv ya galasi nthawi zambiri ikhale yotsika kuposa 0.6. Galasi loteteza kuwala lopanda vacuum limagwiritsa ntchito Low-E imodzi yokha, yomwe imatha kukhala ndi mphamvu yocheperako yotumizira kutentha kuposa galasi loteteza kutentha la Low-E kawiri, ndipo mphamvu yotumizira kuwala yooneka τv imatha kufika pa 0.8.
N'zodziwikiratu kuti mphamvu yoteteza mawu yoyendetsedwa ndi mpweya ya galasi la vacuum ndi yabwino kwambiri. Kutumiza kwa mafunde a mawu kuyenera kudutsa mu sing'anga, kuti galasi la vacuum lithe kuletsa phokoso bwino, ndipo kutetezera mawu ake olemera kumatha kufika pa 40dB, pomwe galasi loteteza lili pafupifupi 30dB yokha.
Mlingo wa vacuum wogwira ntchito (≤0.1 Pa) mu vacuum wosanjikiza ukhoza kusungidwa kwa nthawi yayitali, zomwe zimatsimikiza nthawi ya ntchito ya galasi la vacuum. Opanga apadziko lonse lapansi monga Asahi Glass angapereke chitsimikizo cha zaka 15 cha zinthu zagalasi la vacuum ku Europe ndi Japan, ndipo nthawi yeniyeni yogwirira ntchito ndi zaka zoposa 25. Ndi kupita patsogolo kwa ukadaulo, njirayi yakula pang'onopang'ono, ndipo ukadaulo wagalasi la vacuum wakunyumba wafika pamlingo wapamwamba kwambiri padziko lonse lapansi. Popeza mpweya wopanda mpweya mugalasi lotetezera kutentha udzatuluka pang'onopang'ono pakapita nthawi, izi zimatsimikizira kuti galasi lotetezera kutentha lilinso ndi vuto la nthawi yogwira ntchito.
Poyerekeza ndi galasi loteteza kutentha,galasi loteteza utsiNdi yopepuka komanso yopyapyala. Kukhuthala kwa galasi loteteza nthawi zambiri kumakhala 6 ~ 12mm, kapena kokulirapo, ndipo mkati mwake muli mpweya kapena mpweya wosalowerera, pomwe galasi loteteza mpweya ndi 0.1 ~ 0.2mm yokha. Kuphatikiza apo, galasi loteteza mpweya lokhala ndi galasi loteteza mpweya lokhala pakati pa magalasi awiri, mphamvu yake yotetezera kutentha imatha kuyerekezeredwa ndi galasi loteteza mpweya la magalasi atatu, ndipo chifukwa chakuti galasi limodzi siligwiritsidwa ntchito kwambiri, kulemera kwake kumachepa poyerekeza ndi galasi loteteza mpweya la magalasi atatu 1/3.
Pa ntchito yokonza zitseko ndi mawindo agalasi okhala ndi mawindo a aluminiyamu osweka, tikupereka dongosolo latsopano lokonzanso mawindo akunja: kusunga chimango choyambirira cha zenera, kusintha galasi loyambirira loteteza kutentha ndi galasi losatentha, ndikuyikapo galasi losatseka. Ubwino wa yankho ili ndikupewa kufunikira kosintha zenera lonse, kapena kuwonjezera mawindo akunja, ndi zina zotero. Ntchito yambiri ndi yayikulu, zomwe zingakhudze moyo wabwinobwino wa okhalamo, kotero n'kovuta kukhazikitsa njira zazikulu zokonzanso. Zachidziwikire, yankho ili liyenera kukwaniritsa zofunikira zina: mawonekedwe oyambira a zenera ndi abwino ndipo akadali oyenera kusungidwa. Chifukwa zotsatira zomwe tikufuna kukwaniritsa ndikukonzanso kosunga mphamvu. Mawindo akale akunja akasinthidwa ndi galasi losatsegula, adzapitiriza kugwiritsidwa ntchito kwa zaka zosachepera 15, m'malo mongochotsedwa kwathunthu ndikusinthidwa patatha zaka zochepa kuchokera pakukonzanso, zomwe zimapangitsa kuti pakhale zinyalala zosafunikira.
Zerothermo Yang'anani kwambiri pa ukadaulo wa vacuum kwa zaka zoposa 20, zinthu zathu zazikulu: mapanelo oteteza vacuum kutengera zinthu zoyambira za silika zofukiza za katemera, zamankhwala, zida zozizira, firiji,gulu lophatikizana la vacuum insulation ndi zokongoletsera,galasi losapanga dzimbiri, zitseko ndi mawindo otetezedwa ndi vacuum. Ngati mukufuna kudziwa zambiri zokhudza Mapanelo oteteza utsi a Zerothermo,Chonde musazengereze kulankhulana nafe, komanso mwalandiridwa kuti mudzacheze ku fakitale yathu.
