And instrument software acquires and records the set temperature t of the refrigerating chamber and the temperature t1 of the sensor of the refrigerating chamber in real time.
And thirdly, judging whether T1-T is equal to or greater than T2 (T2 is a set temperature and can be taken as 2 ℃), if the conditions are met, namely the temperature T1 of the sensor of the refrigerating chamber is higher than the set temperature T and reaches a set starting point of the compressor, starting the compressor for refrigeration, starting the refrigerating fan, the freezing fan and the air door, operating the refrigerating fan according to an N4 gear (which indicates that the internal temperature of the refrigerating chamber is high under the condition, the air door, the freezing fan and the refrigerating fan need to be opened, and the refrigerating fan operates at a maximum air gear to enable the internal temperature of the refrigerating chamber to approach or reach the set temperature T), recording the set temperature T of the refrigerating chamber and the temperature T of the sensor in real time, and returning to the judgment logic operation if the T1-T is equal to or greater than T2. When the temperature t1 of the sensor of the refrigerating chamber is higher than the set temperature t, the temperature in the chamber is proved to be higher, and the compressor needs to be started for cooling at the moment, so the condition is satisfied.

Judging whether T1-T is set to be more than or equal to T4 or not, (T4 is set temperature and can be set to be-2 ℃), if the conditions are met, operating the refrigerating fan according to an N2 gear (indicating that the internal temperature of the refrigerating chamber is lower under the condition, an air door, the refrigerating fan and the refrigerating fan need to be opened, and the refrigerating fan operates at a smaller gear, reducing the speed of the fan to enable the temperature of the refrigerating chamber to rise to some extent so that the internal temperature of the refrigerating chamber approaches or reaches the preset temperature T, and N4 is more than N3 and more than N2 and more than N1), recording the set temperature T of the refrigerating chamber and the temperature T of the sensor in real time, and if the conditions are not met, returning to the judgment logic operation.

the judging step is used for judging whether the real-time temperature t1-t is not more than t 5;
in the control step, when t1-t is not more than t5, both the air door and the freezing fan are controlled to be closed, and the refrigerating fan is controlled to operate according to a N1 gear, wherein t5 is a fifth preset temperature, N1 is a first preset air gear, t4 is more than t5 and more than t3, and N1 is more than N2; and when t1-t is set to be more than t5, controlling the air door and the freezing fan to be kept in an opening state, and controlling the refrigerating fan to operate according to the N2 gear.
Judging whether T5 is equal to or less than T1-T (T3 is a set temperature, wherein the temperature can be set to be-1 ℃), if the conditions are met, closing the freezing fan, closing the freezing air door, opening the refrigerating fan, and continuously operating Tmin according to the N1 gear (T is a set time, wherein the time can be set to be 5min) (indicating that the internal temperature of the refrigerating chamber is very close to the preset temperature under the condition, the air door needs to be closed, the refrigerating fan is only required to operate at a low air speed, the air flow in the refrigerating chamber is circulated, the internal temperature of the refrigerating chamber is enabled to be close to or reach the preset temperature T, N4 is larger than N3 and larger than N2 and larger than N1), and if the conditions are not met, returning to the last judgment logic operation.
