Method of manufacturing low-temperature storage and a low-temperature storage

摘要

An object is to provide a method of manufacturing a low-temperature storage in which an insulating performance of an insulating box article (2) is enhanced, and an amount of contents of an inner box can be enlarged. In the low-temperature storage (1) comprising: the insulating box article (2) constituted by placing a foamed insulating material (7) between an outer box (3) and the inner box (4); and a vacuum insulating panel (30) disposed on the surface of the outer box (3) on the side of the foamed insulating material (7), a thickness dimension of the foamed insulating material (7) between the inner box (4) and the vacuum insulating panel (30) is set so that a temperature of the surface of the vacuum insulating panel (30) on the side of the inner box (4) is not less than a predetermined temperature.
