The surface temperature and the bottom temperature of the food are detected simultaneously through the infrared temperature sensor and the bottom temperature sensor of the compartment, and the temperature interval of the maximum ice crystal generation zone is intelligently identified. The invention can quickly reduce the temperature of cold air by increasing the rotating speed of the compressor 15 and reducing the flow of the capillary group, thereby realizing the purpose of quickly passing through the maximum ice crystal generation zone and being beneficial to the long-term preservation of food.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
