Title:
COLD STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2019211151
Kind Code:
A
Abstract:
To provide a cold storage device capable of displaying a cold retention possible time depending on a cold air leakage amount due to change in adiabaticity of a heat insulating material.SOLUTION: A cold storage device comprises a first temperature sensor 12 that detects the temperature of a heat insulating material 16b, and a second temperature sensor 13 that detects the temperature of a space around a cold retention space. Since the state inside the cold storage device 100 with respect to a wall 16 is fixed when a storage chamber 50 is in a cold retention state, a cold air leakage amount of the cold storage device 100 can be obtained, and thus with the cold air leakage amount, a cold retention possible time can be obtained.SELECTED DRAWING: Figure 1
