a cabinet having a first storage compartment, and a second storage compartment maintained at a lower temperature than the first storage compartment;
a first door for opening and closing the first storage compartment and a second door for opening and closing the second storage compartment;
a first temperature sensor for measuring a temperature inside the first storage compartment and a second temperature sensor for measuring a temperature inside the second storage compartment;
a cooling source for generating cold air that is supplied to the first and second storage compartments;
a controller configured to control the cooling power of the cold air supplied to the first and second storage compartments,
wherein the controller is configured to control the cooling power to perform one of a normal storage operation and a load operation,
wherein, in the configuration of the controller,
when a start condition of the load operation is satisfied, the load operation is performed,
when a termination condition of the load operation is satisfied, the load operation is terminated and the normal storage operation is performed,
when the normal storage operation is performed after the load operation is terminated, a re-input prevention control is performed so that the load operation is not performed although the start condition of the load operation is satisfied, and
when a re-input prevention stop condition of the load operation is satisfied while the re-input prevention control is performed, the re-input prevention control is stopped to allow the load operation to be performed when the start condition of the load operation is satisfied.
