the first air conditioner tail end and the second air conditioner tail end are arranged in the second partition cavity up and down along the vertical direction;

the first air conditioning terminal and the second air conditioning terminal are electrically connected in parallel.

10. The refrigerant system as set forth in claim 7, further including: the device comprises a temperature sensor, a comparator, a timer and a controller;

the temperature sensor is arranged in the second partition cavity;

the first end of the temperature sensor is connected with the first end of the comparator;

the second end of the comparator is connected with the first end of the timer;

the second end of the timer is connected with the first end of the controller;

the second end of the controller is connected with the fan array;

the temperature sensor is used for measuring the air temperature in the second compartment and sending the air temperature to the comparator;

the comparator is used for receiving the air temperature, comparing the air temperature with a preset threshold value and outputting a first level signal to the timer when the air temperature is greater than or equal to the preset threshold value;

the timer is used for starting timing when the first level signal is received and stopping timing after a preset time length;

the timer is further configured to send a second level signal to the controller when the first level signal is continuously received within the preset duration;

the controller is used for sending an adjusting instruction to the fan array when receiving the second level signal; and the adjusting instruction is used for indicating the fan array to increase the rotating speed of the fan.
