PROBLEM TO BE SOLVED: To reduce time required to decrease an internal temperature to a set temperature in a chilling operation.SOLUTION: A freezer (1) performs a chilling operation for chilling an interior so that an internal temperature is equal to a set temperature (SP) set in a preset temperature range. The freezer (1) comprises an operation control unit (52) switchably exerting a pull-down control and a capacity control for cooling the interior with a lower cooling capacity than that of the pull-down control in the chilling operation. The operation control unit (52) exerts the pull-down control until a temperature of air blown to the interior reaches at least the set temperature (SP). |
