Abstract
The present invention provides a thermal insulator cabinet having high thermal insulating ability and long-term reliability as well as excellent energy-saving and maintenance properties. The thermal insulator cabinet includes a gas-tight container that is filled with a charging gas and a continuous spacing core and a gas-storage container that communicates with the gas-tight container and is filled with an absorbent for absorbing at least the charging gas, wherein the gas-storage container absorbs the charging gas to make inside of the gas-tight container in a state of reduced pressure.
Claims14
A thermal insulator cabinet comprising
- a gas-tight container that is filled with carbon dioxide gas and
- a continuous-spacing core, and a gas-storage container that communicates with said gas-tight container and is filled with an absorbent for absorbing at least said carbon dioxide gas,
- wherein said gas-storage container absorbs said carbon dioxide gas to make inside of said gas-tight container in a state of reduced pressure.
A method of manufacturing a thermal insulator cabinet, said method comprising the steps of:
- charging a continuous-spacing core into a gas-tight container with a carbon dioxide gas;
- and
- introducing said carbon dioxide gas into a gas-storage container, which is arranged to communicate with said gas-tight container, and causing said carbon dioxide gas to be absorbed by an absorbent in said gas-storage container, thereby making said gas-tight container in a state of reduced pressure.
