Makaaniani Vacuum
ʻO ka manaʻo Vacuum Insulated Glass mai ka hoʻonohonoho ʻana me nā loina like me ka flask Dewar.
Hoʻopau ka ʻumehana i ka hoʻoili wela ma waena o nā ʻāpana aniani ʻelua ma muli o ka conduction gaseous a me ka convection, a hoʻokahi a ʻelua paha ʻāpana aniani alohilohi i loko me nā uhi haʻahaʻa haʻahaʻa e hōʻemi i ka hoʻoili wela radiative i kahi pae haʻahaʻa.Ua hoʻokumu ʻia ka VIG mua o ka honua ma 1993 ma ke Kulanui o Sydney, Australia.Loaʻa ʻo VIG i kahi hoʻokaʻawale wela kiʻekiʻe ma mua o ka insulating glazing maʻamau (IG Unit).
Nā Pōmaikaʻi Nui o VIG
1) Hoʻopili wela
Ho'emi nui ka hakahaka o ka vacuum i ka conduction a me ka convection, a me ka uhi ha'aha'a-E e ho'emi ana i ka radiation. Hoʻokahi wale nō ʻāpana o ke aniani haʻahaʻa-E e ʻae i ka mālamalama maoli i loko o ka hale. ʻO ka mahana o ka VIG glazing i loko o kahi kokoke i ka lumi lumi, ʻoi aku ka ʻoluʻolu.
2) Hoʻopili kani
ʻAʻole hiki ke hoʻolele ʻia ke kani i loko o kahi hakahaka. Ua hoʻomaikaʻi nui nā pane VIG i ka hana acoustic attenuation o nā puka makani a me nā facades. Hiki i ka VIG ke hōʻemi maikaʻi i nā leo waena a me nā haʻahaʻa haʻahaʻa, e like me ke kaʻa alanui a me ka walaʻau ola.
3) Māmā a lahilahi
ʻOi aku ka lahilahi o ka VIG ma mua o ka pūʻulu IG me ka lewa ea ma kahi o kahi ākea 0.1-0.2 mm. Ke hoʻohana ʻia i kahi hale, ʻoi aku ka lahilahi a ʻoi aku ka māmā o ka puka makani me ka VIG ma mua o kēlā me ka ʻāpana IG. ʻOi aku ka maʻalahi a ʻoi aku ka maikaʻi o ka VIG ma mua o ka triple-glazing e hoʻohaʻahaʻa i ka U-factor o ka puka makani, ʻoi aku hoʻi no nā hale passive a me nā hale ʻole-ikaika. No ka hoʻihoʻi hou ʻana o ka hale a me ke pani aniani, makemake ʻia ka VIG lahilahi e nā mea nona nā hale kahiko, no ka mea, ʻoi aku ka kiʻekiʻe o ka hana, ka mālama ʻana i ka ikehu, a me ka lōʻihi.
4) Ke ola lōʻihi
He 50 mau makahiki ko mākou VIG, a hiki i ke ola i manaʻo ʻia ke hiki i 30 mau makahiki, e hoʻokokoke ana i ke ola o ka puka, ka puka makani, a me nā mea paʻa pā.
