At the moment, whether the user puts the 2 nd batch of meat into the second compartment 21 is judged, if yes, the second condition is judged, if not, the first compartment 11 enters the second stage, the compressor operates for 5-8 minutes at K2, the air supply quantity is reduced, the meat temperature of the first compartment 11 rapidly rises to T1 (-18-26 ℃), whether the meat temperature of the first compartment 11 rises to T1 (-18-26 ℃) is detected, if yes, the compressor operates at K3, energy-saving storage is realized, and if not, the compressor continues to operate at K2 until the temperature rising is finished (the temperature rises to T1).
In the second case: the user puts 2 batches of meat into the first compartment 11 and the second compartment 21, respectively, at different time intervals. The user puts the first batch of meat into the first compartment 11 first, and the compressor begins to operate for 3-5 minutes with K1, and the first air door is opened and refrigerates rapidly, discerns whether the meat temperature in the first compartment 11 reaches T2(-30 ℃ to-40 ℃), if yes, the first air door is closed, waits for the second compartment 21 meat to finish cooling.

Midway, a user puts the 2 nd batch of meat into the second compartment 21, if the second compartment 21 is to be cooled, the first compartment 11 is judged to be the first stage, the second stage or the third stage, if the first compartment 11 is judged to be in the first stage, the air door of the second compartment 21 is opened to rapidly cool, the compressor runs by using K1 until the temperature of the meat in the second compartment 21 reaches T2(-30 ℃ to-40 ℃), whether the meat in the second compartment 21 reaches T2(-30 ℃ to-40 ℃), if yes, the first compartment 11 and the second compartment 21 simultaneously enter the second stage, and if not, the compressor continues to run by using K1 until the cooling is finished. After the first compartment 11 and the second compartment 21 enter the second stage, a temperature return program is started, the first air door is opened, the second air door is closed, the compressor operates for 5-8 minutes at K2, the meat temperature in the first compartment 11 rapidly returns to T1(-18 ℃ -26 ℃), whether the meat temperature in the first compartment 11 reaches T1(-18 ℃ -26 ℃) or not is detected, if the meat temperature reaches T1(-18 ℃ -26 ℃), the first air door is closed, the second air door is opened, the second compartment 21 rapidly cools, whether the meat temperature in the second compartment 21 reaches T1(-18 ℃ -26 ℃) or not is detected, if the meat temperature reaches T1(-18 ℃ -26 ℃), the first compartment 11 and the second compartment 21 enter the third stage together, the first air door and the second air door are both opened, the compressor operates at K3, energy-saving storage is achieved, if the meat temperature in the second compartment 21 does not reach K2, and the temperature return of the second compartment 21 is waited to finish.
If the first compartment 11 is judged to be in the second stage or the third stage, the first air door is closed, the meat in the first compartment 11 automatically returns to the temperature of T1(-18 ℃ -26 ℃), the air door of the second compartment 21 is opened to rapidly refrigerate, whether the temperature of the meat in the second compartment 21 reaches T2(-30 ℃ -minus 40 ℃) is detected, if yes, the second compartment 21 enters the second stage, the air supply amount is reduced, the compressor operates for 5-8 minutes at K2, the temperature of the second compartment 21 quickly returns to the temperature of T1(-18 ℃ -26 ℃), and if not, the compressor continues to operate at K1 until the temperature reduction is completed. And continuously detecting whether the temperature of the meat in the second compartment 21 is increased to T1 (-18-26 ℃), if so, operating the compressor with K3(K1 is more than or equal to K3 is more than or equal to K2), saving energy, and if not, operating the compressor with K2 continuously until the temperature is increased.
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.
