Insulation Gas vacuum wika

Vacuum technology is also used in some non-transparent insulation products called vacuum insulated panels. An older-established way to improve insulation performance is to replace air in the space with a lower thermal conductivity gas. Gas convective heat transfer is a function of viscosity and specific heat.hgis Gas-Insulated-Substations vacuum wika
