Document Type and Number:
Japanese Patent JP2023110768
Kind Code:
A
Abstract:
To provide a cooling device capable of individually keeping an inner temperature each of a plurality of storages in each set temperature zone irrespective of an outside temperature of a storage part including the plurality of storages while achieving energy saving.SOLUTION: A specimen storage device 100 includes: a compressor 4; a condenser 5; a plurality of evaporators including a first evaporator 21 and a second evaporator 22; expansion valves 71a, 71b; expansion valves 72a, 72b; and a storage part 1 including a first storage 11 and a second storage 12. When an outside temperature TO of the storage part 1 is lower than a set temperature zone in the first storage 11, the specimen storage device 100 adjusts a temperature of a coolant condensed by the condenser 5 and flowing into the first evaporator 21 by the expansion valves 71a, 71b, and performs operation of heating air in the first storage 11 by heat exchange between the coolant flowing in the first evaporator 21 and air in the first storage 11.SELECTED DRAWING: Figure 5
