Abstract

A management system (100) for a vacuum heat insulating body (10) includes: an inspection device (70) that inspects heat insulation performance of the vacuum heat insulating body (10); a storage portion (105) that stores information regarding the inspected heat insulation performance; an estimating portion (101) that estimates a remaining life, which is the rest of a life of the vacuum heat insulating body (10), from a time-lapse change of the heat insulation performance stored in the storage portion (105); and a determining portion (102) that determines whether or not the remaining life is a predetermined period of time or more.

Dependent claims

A management system for a vacuum heat insulating body,

the management system comprising:
an inspection device that inspects heat insulation performance of a vacuum heat insulating body:
a storage portion that stores information regarding the inspected heat insulation performance;
an estimating portion that estimates a remaining life, which is the rest of a life of the vacuum heat insulating body, from a time-lapse change of the heat insulation performance stored in the storage portion;
and
a determining portion that determines whether or not the remaining life is a predetermined period of time or more, wherein
the vacuum heat insulating body includes a gas adsorbing member;
the heat insulation performance of the vacuum heat insulating body changes through a first period in which a change rate of the heat insulation performance is constant, a second period which is continuous with the first period and in which the change rate is variable, and a third period which is continuous with the second period and in which the change rate is constant;
and
the life is a total period including the first period and the second period.
