the method comprises the following steps: setting the target temperature value of the chamber to be T0;
step two: setting a room temperature coarse adjustment lower limit temperature value as T11, setting a coarse adjustment upper limit temperature value as T12, and setting T11 to be more than T0 to be more than T12; wherein T11 is greater than 0;
step three: setting the lower limit temperature value of the fine adjustment of the compartment temperature as T21, setting the upper limit temperature value of the fine adjustment as T22, and setting T11 to be more than T21 to be more than T0 to be more than T22 to be more than T12;

step five: setting time parameters t1 and t2, wherein t2 is greater than t1, and t1 is greater than 0; every time when heating or cooling is finished once, T1 and T2 respectively start to count again, the compartment temperature is recorded once every 1min from the time T1, the compartment temperature value T01 is recorded at the time T1, and the compartment temperature value T01n is recorded once every minute from the time T1 to the time T2, such as T011, T012, T013 and … … T01 n;
at time T2, recording a room temperature value T02, recording room temperature values T02n every minute after time T2, such as T021, T022, T033 … … T02n, wherein T01n corresponds to T02n one by one, calculating △ T0-T02-T01, △ T0-T021-T011, △ T0-T022-T012, and so on, namely calculating a value of △ T0 updated every 1min after time T2, and performing operation mode judgment according to the positive and negative values of △ T0;
if the calculation △ T0 is T02-T01, when △ T0 is positive, it indicates that the temperature in the compartment is gradually increasing, and only when the compartment temperature is greater than T22, the cooling mode is operated, and other times the compartment is not cooled and is not heated;
when △ T0 is not positive, it indicates that the temperature in the compartment is gradually decreasing, and only when the compartment temperature is less than T21, the heating mode is operated, and other times the compartment is neither cooled nor heated.
If the compartment operation is finished once, and the time t2 is not reached, the cooling or heating is needed again, and the latest compartment operation mode is not determined, the previous compartment operation mode is maintained.
Step six: and step five, judging the cooling mode, when the temperature in the compartment reaches T22, starting cooling by the system, and cooling the temperature in the compartment to T21, wherein the temperature change trend of the compartment is gradually increased, so that the temperature in the compartment is finely adjusted to T21, the temperature in the compartment is more favorably kept between the finely adjusted upper and lower limit temperatures, the temperature in the compartment is closer to and kept at the target temperature T0, the cooling is finished after the temperature in the compartment reaches T21, the step five is returned, the temperature in the compartment is continuously detected in real time, and the latest compartment operation mode is judged.
If it is determined in the step five that the operation mode is the heating mode, it is described that the temperature in the compartment tends to decrease, and if the temperature in the compartment reaches T21, the temperature in the compartment is heated to T22, and since the temperature change in the compartment gradually decreases, the temperature in the compartment gradually decreases after the temperature in the compartment is heated to T22 when the temperature in the compartment reaches T21, and therefore, it is also easier to make the temperature in the compartment approach and maintain the temperature in the target temperature T0 position, and after the heating is completed, the operation mode returns to the step five, and the real-time detection of the temperature in the compartment is continued, and the latest compartment operation mode is determined.
Example one
The method comprises the following steps: setting the target temperature value of the chamber to be 20 ℃;
step two: setting the lower limit temperature value of coarse adjustment of the temperature of the compartment as 15 ℃ and the upper limit temperature value of coarse adjustment as 25 ℃;
step three: setting the lower limit temperature value of the fine adjustment of the compartment temperature to be 18 ℃ and the upper limit temperature value of the fine adjustment to be 22 ℃;
step four: after the operation warm-keeping function of the independent refrigerating system chamber of the refrigerator is started, detecting whether the temperature in the chamber is higher or lower than 20 ℃, if so, adjusting the temperature of the chamber to the target temperature value of 20 ℃ through heating or refrigerating, and finishing heating or refrigerating;
if the temperature in the detection chamber is just 20 ℃, the temperature in the detection chamber is in the target temperature, so that heating or refrigerating processing is not required to be executed, and the temperature change trend detection is executed in the step five;
step five: when heating or refrigeration is finished, room temperature value T01 is recorded in 5min, room temperature value T011 in 6min, room temperature value T012 in 7min, and the rest is repeated until 19 min;
recording room temperature value T02 at 20 min; recording the room temperature value T021 in 21min, recording the room temperature value T022 in 22min, and the like;
△ T0 is calculated to be T02-T01, △ T0 is calculated to be T021-T011, △ T0 is calculated to be T022-T012, and the like, wherein temperature values recorded every minute after 20min and temperature values recorded every minute between 5min and 20min are in one-to-one correspondence in sequence, namely △ T0 values are calculated and updated every 1min after 20 min.
If the refrigerator is operated for 22min and the compartment temperature value T022 is 19 ℃ and the refrigerator is operated for 7min and the compartment temperature value T012 is 21 ℃, △ T0 is T022-T012 is 19 ℃ -21 ℃ is-2, which indicates that the temperature in the compartment is gradually reduced after the refrigeration stop is performed in the fourth step, and therefore, the heating mode is operated only when the temperature in the compartment is lower than 18 ℃ and the temperature in the compartment is prevented from being lower than 18 ℃;
if the refrigerator is operated at the 13 th minute, △ T0 is calculated and updated as 21 ℃. -19 ℃. 2, it is described that after the heating in the compartment is stopped at the fourth step, the temperature in the compartment is gradually increased due to the temperature inertia or the influence of the ambient temperature, and thus, it is judged that the compartment is operated in the cooling mode next time, and the cooling mode is operated only when the temperature is higher than 22 ℃, preventing the temperature in the compartment from being higher than 22 ℃.
Step six, when the latest △ T0 calculated in the step five is a positive value and the temperature in the compartment reaches 22 ℃, the system starts to refrigerate and refrigerates the temperature in the compartment to 18 ℃, because the temperature change trend of the compartment is gradually increased, the temperature in the compartment is finely adjusted to 18 ℃, the temperature in the compartment is more favorably kept between the upper limit temperature and the lower limit temperature of the fine adjustment, the refrigerating time is shorter, the deviation of the temperature in the compartment due to temperature inertia is very small, so that the temperature in the compartment is closer to and kept at the position of the target temperature of 20 ℃, the refrigeration is finished after the temperature in the compartment is refrigerated to 18 ℃, the step five is returned, and the real-time detection of the temperature in the compartment is continuously carried out;
when the newly calculated △ T0 in the fifth step is a negative value, it is described that the temperature in the room tends to decrease, and when the room temperature reaches 18 ℃, the room temperature is heated to 22 ℃, and since the change in the room temperature gradually decreases, the temperature in the room gradually decreases after the room temperature is heated to 22 ℃ when the temperature reaches 18 ℃, and also since the heating time is short at this time, the deviation of the room temperature due to temperature inertia is small, the temperature in the room is more likely to be brought close to and maintained at the target temperature of 20 ℃, and after the heating is completed, the process returns to the fifth step, and the real-time detection of the room temperature is continued.
