Qhov tseeb, insulated iav thiab nqus iav yog ob hom sib txawv ntawm cov iav. Qhov sib txawv tuaj yeem paub qhov txawv ntawm cov txheej txheem ntau lawm:
Insulating iav
Insulating iav tau tsim los ntawm Asmeskas nyob rau xyoo 1865. Nws yog hom tshiab ntawm cov khoom siv tsev uas muaj cov cua sov zoo, rwb thaiv tsev suab, zoo nkauj thiab daim ntawv thov, thiab tuaj yeem txo qhov nyhav ntawm lub tsev. Nws siv ob (los yog peb) daim khob thiab siv lub zog muaj zog thiab siab muaj zog. Cov airtight composite nplaum txuas cov ntawv iav thiab cov ntawv txhuas txhuas thav duab uas muaj cov desiccant ua kom muaj suab nrov tiv thaiv zoo rwb thaiv tsev iav. Insulating iav muaj ntau lub zog zoo dua li cov dog dig uas muaj ob txheej iav, yog li nws tau lees paub los ntawm cov teb chaws thoob qab ntuj. Insulating iav yog kom muaj txiaj ntsig zoo txhawb nqa ob lossis ntau daim ntawm lub khob kom raug sib cais thiab sib khi thiab sib khi ib ncig ntawm iav los tsim cov roj qhuav ntawm txheej txheej iav. Chaw seem iav. Cov ntaub ntawv tseem ceeb yog iav, aluminium spacers, lub kaum sab xis pob, butyl roj hmab, polysulfide roj hmab, thiab desiccant.
Nqus iav:
Nqus iav yog yuav ntim ob daim ntawm daim iav tiaj tus, nqus lub qhov sib txawv thiab khi lub qhov dej kom zoo. Qhov sib txawv nruab nrab ntawm ob daim ntawm iav yog 0.1-0-0. 2 hli. Feem ntau, tsawg kawg ib qho ntawm ob daim ntawm lub khob iav yog Tsawg-emissivity iav, ua li no, txo cov hluav taws kub kom tsawg los ntawm kev sib dhos, convection thiab hluav taws xob ntawm lub khob iav. Nws cov ntsiab cai ua haujlwm yog tib yam li ntawm cov iav thermos. Lub tshuab nqus iav yog cov txiv ntoo ntawm kev koom tes ntawm iav tshuab thiab cov khoom siv science, lub tshuab nqus tsev, tshuab ntsuas lub cev, kev lag luam thev naus laus zis thiab kev tshawb fawb lub tsev, thiab lwm yam.
