<p>The present invention relates to a cool-keeping system which can store or convey an article of storage within a desired temperature range for a long time. More particularly, the invention relates to a cool-keeping system which achieves an effect of extending the time for keeping under cold insulation, which time has never been achieved with conventional single-layer cool- keeping systems, by installing a partition member inside a first box, which is located on the outer side, and introducing a coolant into the space between the first box and the partition member and the space between the partition member and the article of storage, thereby to dispose an insulating material and a material having high latent heat or high heat capacity in an alternating manner.</p> |
