VACCUM HEAT INSULATING MATERIAL, REFRIGERATOR USING IT AND MANUFACTURING METHOD THEREOF

摘要

The invention provides a vacuum insulation panel (20) to which moisture and gas do not easily adsorb while it is being processed or being in storage in an unfinished state. The vacuum insulation panel (20) includes a core (21) provided with air circulation, a getter material (22) which adsorbs moisture and gas from the core (21), an inner film bag (23) which accommodates the core (21) and the getter material (22), and an outer barrier bag (24) which accommodates the inner film bag (23) . The getter material (22) is filled in an incision provided on the surface of the core (21). To prevent the getter material (22) from getting out of the incision, the opening of the incision is narrowed by evacuating air from the interior of the inner film bag (23) and, concurrently, compressing the inner film bag (23) and the core (21).
