PROBLEM TO BE SOLVED: To provide a cooling storage chamber capable of avoiding the remarkable reduction of a temperature in a storage chamber compared with a set temperature. SOLUTION: A control device 24 is equipped with a timer to carry out a cold storage agent freezing mode, wherein a compressor 37 is operated at a preset time to freeze a cold storage agent 13 by a cooler 34, and a cold storage agent cooling mode, wherein the compressor 37 is stopped to cool the inside of the storage chamber 5 by the cooling effect of the cold storage agent 13, while the control device 24 is provided with a temperature compensating heater or an electric heater 25 to prevent the supercool of inside of the storage chamber 5 under the cold storage agent freezing mode. |
