In addition, the first to third storage chambers 20a, 21
a and 22a are first to third Peltier elements 26 and 3
In order to increase the 0, 34 capacity, generally, the heat is radiated by using brine due to the characteristics of the Peltier device in which the capacity and efficiency increase as the temperature of the heat radiating surface becomes lower and the temperature difference with the cooling surface becomes smaller.
