PROBLEM TO BE SOLVED: To improve heat insulating efficiency in a storage space 3 without using a refrigeration machine 16 of large capacity and large size, and reducing load of the refrigeration machine 16.SOLUTION: A storage device includes a freezer 1, a partitioning wall 7 for dividing the inside of the freezer 1 into the storage space 3 and a thermal storage space 4 for accommodating a latent heat storage material 14, the refrigeration machine 16 generating cold air of a prescribed temperature and distributing the same, an air supply passage 19 for supplying the cold air to the storage space 3 and the thermal storage space 4, a switch damper 20 for switching the cold air to be supplied to only the storage space 3, only the thermal storage space 4, or both of the storage space 3 and the thermal storage space 4, a communication passage 10 disposed on the partitioning wall 7 for communicating the storage space 3 with the thermal storage space 4, an opening/closing damper 11 for opening and closing the communication passage 10, a recycling passage 29 for communicating the thermal storage space 4 with the refrigeration machine 16, and a recycling passage damper 30 for opening and closing the recycling passage 29.SELECTED DRAWING: Figure 1 |
