Abstract:
In order to reduce power consumption while ensuring the quality of preservation of an object to be refrigerated in a low-temperature storage for cooling and storing the object to be refrigerated at a predetermined temperature, specifically disclosed is a low-temperature storage (1) which is provided with a heat-insulating housing (2) comprising an accommodating part (21) that accommodates an object to be refrigerated, a door (3) provided in the heat-insulating housing (2), a cooling mechanism (71) for cooling the accommodating part (21), a temperature sensor (211) for measuring the temperature of the accommodating part (21), and an opening/closing sensor (212) for detecting the opening/closing of the door (3), and which performs control so that the temperature of the accommodating part (21) becomes a preset target temperature. In said low-temperature storage, the settings of a first temperature, a second temperature higher than the first temperature, and a switching time are accepted, the elapsed time between the time of opening/closing of the door (3) and the present time is measured, the target temperature is set to the first temperature when the door (3) is opened/closed, and the target temperature is set to the second temperature when the elapsed time reaches the switching time or longer.
