<p><P>PROBLEM TO BE SOLVED: To provide a refrigerator which takes into account cooling efficiency and safety by using a hydrocarbon-based refrigerant and a heat-insulated structure in which the inside of a structure itself is reduced in pressure, and sealing highly active gas absorbent, even in the case of using it, in a sealable container. <P>SOLUTION: The refrigerator 1 comprises a heat-insulated structure 2 including a structure 3, a gas absorbent 4, a container 5 containing the gas absorbent and a porous material 6, the inside of the structure 3 being reduced in pressure; and a refrigeration cycle sealing isobutane. The gas absorbent is sealed in the sealable container 5, whereby even when combustible hydrocarbon refrigerant is used, it can be separated from the gas absorbent during manufacturing, during use and in recycling after use, and the refrigerator 1 that takes into account safety can be obtained. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
