Therefore, the whole temperature in the storage space can be controlled within the optimal fresh-keeping range, and the temperature uniformity in the storage space can be controlled.
What should be uniformly stated is: tmin is the lowest temperature value in the actual temperature range, tmax is the highest temperature value in the actual temperature range, tt _ min is the lower limit value of the optimum storage temperature in the optimum storage temperature range, and Tt _ max is the upper limit value of the optimum storage temperature in the optimum storage temperature range.

Specifically, the direction of the air outlet can be set to be a single direction, and in specific application, the direction of the air outlet can also be set to be multi-direction, namely, the air outlet can be turned. Therefore, the air flow direction in the storage space can be prevented from being adjusted through the direction of the air outlet when the goods are placed or the air channel is unreasonably designed and the temperature cannot be uniformly controlled, so that the optimal storage temperature range is reached.

In practical application, the camera unit can be used for shooting the stored articles to obtain the pictures of the articles to be stored, and further automatically extracting the optimal storage temperature range of the articles to be stored according to the preset corresponding relation between the types of the articles to be stored and the optimal storage temperature range.
It should be noted that the method for acquiring the optimal storage temperature range of the object to be stored is not limited to the manual input method and the automatic acquisition method by the camera unit, and other methods can be used as long as the optimal storage temperature range of the object to be stored can be acquired.

if so, controlling the working state of the temperature adjusting equipment to be kept unchanged;
if not, the working state of the temperature adjusting equipment is changed.
Thus, by judging whether the temperature of the storage space is suitable for storing the articles, the temperature in the storage space can be adjusted in a self-adaptive manner, and the energy consumption of the temperature adjusting equipment is reduced.

The temperature control method provided by the embodiment of the invention comprises but is not limited to the independent temperature zone control of a multi-temperature zone refrigerator, the temperature uniformity control of a refrigerator, a container and the like.
Specifically, in one embodiment of the present invention, a refrigerator is selected as the storage space, the stored items are fruits and vegetables, and the temperature adjustment device is a refrigerator. Generally, fruits and vegetables have an optimum storage temperature range. Assuming that the lower limit value of the optimal storage temperature of the fruits and the vegetables is Tt _ min, and the upper limit value of the optimal storage temperature is Tt _ max; the values of the temperature measured by a plurality of temperature sensors in the refrigerator are respectively T1, T2 and T3 \ 8230Tn, wherein the highest temperature is Tmax, and the lowest temperature is Tmin.
There are 3 cases of refrigerator start-up: the first is when the lowest temperature Tmin of the refrigerator is higher than the lower limit Tt _ min + Deltat of the optimal storage temperature and the highest temperature Tmax is higher than the upper limit Tt _ max + Deltat of the optimal storage temperature; the second one is that the lowest temperature Tmin of the refrigerator is less than the lower limit value Tt _ min-delta t of the optimal storage temperature, and the highest temperature Tmax is less than the upper limit value Tt _ max-delta t of the optimal storage temperature; thirdly, the lowest temperature Tmin of the refrigerator is higher than the lower limit value Tt _ min + Δ t of the optimal storage temperature and the highest temperature Tmax is lower than the upper limit value Tt _ max- Δ t of the optimal storage temperature, so that the temperature control is not needed.
For example, when the refrigerator starts the first situation:
(1) When the lowest temperature Tmin (2 ℃) of the refrigerating box is higher than the lower limit value Tt _ min + delta t (0 ℃ C. +1 ℃) of the optimal storage temperature and the highest temperature Tmax (6 ℃) is higher than the upper limit value Tt _ max + delta t of the optimal storage temperature (4 ℃ C. +1 ℃):
the target temperature of the refrigerator is set to Tt = Tt _ min (0 ℃), and the refrigerator is cooled quickly.
(2) If the highest temperature Tmax (2 ℃) of the refrigerating box is lower than the upper limit value Tt _ max-delta t (4 ℃ -1 ℃) of the optimal storage temperature or the lowest temperature Tmin (-2 ℃) of the refrigerating box is lower than the lower limit value Tt _ min-delta t (0 ℃ -1 ℃):
the target temperature Tt = Tt + Δ t (2 ℃ +1 ℃), and the target temperature is automatically raised, thereby reducing the cooling capacity. Tt is limited between Tt _ min and Tt _ max, Δ t > =0.
(3) If the highest temperature Tmax (6 ℃) of the refrigerator is higher than the upper limit value Tt _ max + delta t (4 ℃ +1 ℃) of the optimal storage temperature:
the target temperature Tt = Tt-delta t (2 ℃ -1 ℃) of the cold machine is reduced, and the refrigerating capacity is increased. Tt is limited between Tt _ min and Tt _ max.
(4) If the refrigerating machine refrigerates for a long Time and exceeds the Time _ Max, the highest temperature Tmax (6 ℃) of the refrigerating box is still higher than the upper limit value of the optimal storage temperature and is Tt _ Max + delta t (4 ℃ plus 1 ℃), the refrigerating box cannot realize uniform temperature control in a target temperature range, at the moment, the driver can be informed of the fact that the temperature of goods exceeds the control range through alarming, the risk of corrosion damage of the goods such as fruits and vegetables exists, and the driver can optimize goods placement and refrigerating air channel design according to the alarming, so that the risk of corrosion damage of the fruits and vegetables is avoided.
