when the first refrigeration cycle loop and the second refrigeration cycle loop are both in a stop working state, acquiring the humidity in the first wine storage cavity 210 and the second wine storage cavity 220, and controlling the air supply device 600 corresponding to the wine storage cavity with the humidity reaching the stop preset humidity corresponding to the wine storage cavity to stop working;
when the first refrigeration cycle loop, the second refrigeration cycle loop and the 2 air supply devices 600 are all in a stop working state, the temperatures in the first wine storage cavity 210 and the second wine storage cavity 220 are continuously obtained, if the temperature of a certain wine storage cavity is in a set temperature fluctuation interval, the wine storage cavity is continuously controlled according to the control process after the Nth stop, and if the temperature of a certain wine storage cavity is not in the set temperature fluctuation interval, the wine storage cavity is controlled according to the process of the previous N-time start-stop control.
Specifically, the process of the previous N start-stop control in this embodiment is:
the temperature in the first wine storage cavity 210 and the second wine storage cavity 220 is detected, when the temperature in the first wine storage cavity 210 is detected to reach the starting preset temperature, the first refrigeration cycle loop is controlled to be switched on through switching of the electromagnetic valve 800, and when the temperature in the first wine storage cavity 210 is detected to reach the stopping preset temperature, the first refrigeration cycle loop is controlled to be switched off through switching of the electromagnetic valve 800.
