A refrigeratorcomprises at least one box-shaped storage compartmentand a heat radiating member. The storage compartmentis formed in such a way that one side of a frame formed by a wall member is closed and the other thereof is provided with an opening surface configured to be opened or closed by a door. The wall member includes a hollow structure composed of a plurality of plate membersandand a foam insulationfilled in the hollow structure. The heat radiating memberis arranged in the wall member. In the wall member, a pressure memberconfigured to press the heat radiating member against the plate member is provided. The pressure memberis a material configured to press the heat radiating memberunder predetermined conditions.

Refrigerator

In an insulator including an adsorbent configured to adsorb gas, an initial adsorption performance of the remaining gas inside the insulator using the adsorbent and a long-term adsorption performance of gas introduced into the insulator from the outside are improved so that the short-term performance and the long-term performance of the insulator can be simultaneously improved. An adsorbent that is a first part of an adsorbent included in a vacuum insulator is accommodated in a first space formed with an inside surface of a container, and an adsorbent that is a second part of the adsorbent is dispersed into a second space formed with an inside surface of an outer envelope and an outside surface of the container.

Vacuum insulator, method of manufacturing the same and refrigerator having the same

Provided is a vacuum insulator having both an excellent insulating performance and an excellent bending strength. A vacuum insulator () is configured by a sack-shaped enveloping member () and at least one sheet () including a plurality of inorganic fibers and includes a core member () enclosed in the enveloping member (). The sheet () includes a plurality of bundled inorganic fibers () formed by bundling some inorganic fibers from among the plurality of inorganic fibers. At least a part of the bundled inorganic fibers () are in contact with each other.
