1. A cooling device that cools foods in a box at high humidity, the cooling device comprising:
a heat exchanger configured to perform heat exchange between a medium circulating in the cooling device and air circulating in the box;
a fan configured to take in the air in the box in which the foods have been cooled at high humidity and to blow the air toward the heat exchanger; and
a controller configured to minimize a temperature difference between a temperature of a heat transferer of the heat unit exchanger and a temperature of the air taken in by the fan while maintaining a state in which moisture adheres to the heat transferer of the heat exchanger by adjusting an inlet temperature of the medium entering the heat exchanger and a rotating speed of the fan without using a sprinkler.
