Title:
VACUUM HEAT INSULATION BOX
Document Type and Number:
Japanese Patent JP2015105806
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vacuum heat insulation box for solving the problem that an adsorption agent of physical absorption and an adsorption agent of chemical absorption change the adsorptivity by use temperature, and consequently, variance may be caused in heat insulation property of a vacuum heat insulation box using a vacuum insulation panel, due to a position where each adsorption agent is sealed.SOLUTION: The vacuum heat insulation box includes a vacuum insulation panel which has a sheet for blocking passage of gas, a core material having heat insulation, and at least one adsorption agent for absorbing gas, and keeps a sealed inside vacuum by sandwiching the core material and the adsorption agent between the sheets, and sealing in an evacuated state. The adsorption agent is arranged in a prescribed position, based on a condition concerning a temperature in the vacuum insulation panel at the time of installation.
