The closed box body can be internally provided with a temperature sensor for detecting the room temperature inside the closed box body storing the target freezing object in real time.

Firstly, detecting the second surface temperature of the target frozen object in real time; and then, when the second surface temperature is in a second preset range within a second preset time, performing cryopreservation on the target frozen object.
And detecting in real time to obtain a second surface temperature of the target frozen object, and when the second surface temperature is within a second preset range within a second preset time, indicating that the inner temperature and the outer temperature of the target frozen object are consistent, and at the moment, completing the supercooling freezing process of the surface target frozen object, and performing the next conventional freezing storage on the surface target frozen object.
In the supercooling freezing control method, when the target frozen object is frozen and preserved, that is, the normal freezing and preserving process includes the steps of:
controlling the refrigerating device to operate according to the corresponding temperature of the refrigeration storage;
detecting the room temperature of the space where the target freezing object in the freezing device is located in real time;
when the current room temperature is greater than a first preset threshold value, controlling a refrigerating device and an electromagnetic field device in the refrigerating device to be started;
and when the current room temperature is less than or equal to a second preset threshold, controlling a refrigerating device and an electromagnetic field device in the refrigerating device to be closed.
Wherein the cryopreservation corresponds to temperatures generally below-18 ℃. When the target frozen object is subjected to a normal freezing preservation after the target frozen object is subjected to a super-freezing process, the refrigeration device and the electromagnetic field device can be controlled to be started according to the room temperature, and the electromagnetic field device can be started when the temperature rises during the freezing preservation, so that the recrystallization can be favorably reduced. In addition, energy consumption can be saved by intermittently operating the electromagnetic field device.
In summary, the present application provides a method for controlling supercooling freezing, the method comprising: detecting the room temperature of a space where a target freezing object in a freezing device is located in real time; the room temperature comprises the room temperature at the current moment and the room temperature at the moment before the current moment; determining the current room temperature variation according to the room temperature at the current moment and the room temperature at the moment before the current moment; and when the current room temperature variation is larger than a preset threshold value, performing supercooling freezing on the target frozen object. The current room temperature variation can be determined by detecting the room temperature of the space where the target freezing object in the freezing device is located in real time. Because the target frozen object can release a large amount of heat when the supercooling state is released, the supercooling release action of the target frozen object can be accurately identified through the judgment of the current room temperature variation, the target frozen object is further subjected to supercooling freezing operation, the target frozen object is immediately started to be quickly frozen after the supercooling state is released, the problem of uneven ice crystal distribution caused by slow freezing speed due to the difference of the supercooling release process is avoided, the freezing mechanical damage caused by the ice crystal is reduced, and the freezing effect is improved.
