To prevent freezing of stored articles by resolving low-temperature abnormality in a storage compartment of a cooling storage.

This cooling storage R in which the storage compartment 5 is cooled by a cooling unit 10, includes an inside temperature sensor 31 detecting a temperature in the storage compartment 5, and a control device 33 controlling the cooling unit 10 on the basis of output of the inside temperature sensor 31, the control device 33 executes a temperature rise acceleration control for accelerating temperature rise in the storage compartment 5 when the temperature in the storage compartment 5 is lowered to a prescribed low-temperature abnormal zone, and determines whether a prescribed low-temperature warning and/or low-temperature abnormality processing are executed or not according to a situation of temperature change in the storage compartment 5 after executing the temperature rise acceleration control.
