VACUUM ADIABATIC BODY, FABRICATION METHOD FOR THE VACUUM ADIABATIC BODY, POROUS SUBSTANCE PACKAGE, AND REFRIGERATOR

摘要

A vacuum adiabatic body includes: a first plate member defining at least one portion of a wall for a first space; a second plate member defining at least one portion of a wall for a second space having a different temperature from the first space; a sealing part sealing the first plate member and the second plate member to provide a third space that has a temperature between the temperature of the first space and the temperature of the second space and is in a vacuum state; a supporting unit maintaining the third space; a heat resistance unit for decreasing a heat transfer amount between the first plate member and the second plate member; and an exhaust port through which a gas in the third space is exhausted, wherein the supporting unit includes: a porous substance; and a film made of a resin material, the film accommodating the porous substance thereby. Accordingly, it is possible to provide a vacuum adiabatic body through an inexpensive process.
