The temperature difference existing for machine temperature is bigger, stores food to avoid influencing refrigerator room, and refrigerating system needs to freeze with most fast speed,
Therefore, it is fully open to control N number of air door, while freezing blower with maximum speed F1 operating.
Wherein, control door opening and the method for adjusting rotation speed of fan can refer to the description of above-described embodiment, herein no longer
It repeats.
Table 1
| Temperature range | Door opening quantity | Freeze rotation speed of fan |
| Tr-Toff≥T1 | N | F1 |
| T1 > Tr-Toff >=T2 | N-1 | F2 |
| … | … | … |
| Tn-2 > Tr-Toff >=Tn-1 | 2 | Fn-1 |
| Tn-1 > Tr-Tof >=Tn | 1 | Fn |
The temperature range according to locating for the temperature difference as a result, determines the first quantity of the air door that refrigerating system needs to open, and
Freeze the rotating speed of target revolving speed of blower, wherein the temperature difference is bigger, then the unlatching quantity of air door is bigger, freezes the rotating speed of target of blower
It is bigger, so control refrigerating system open with the consistent air door of the first quantity and adjust freezing blower revolving speed to rotating speed of target into
Row operation, makes the refrigerating speed of refrigerating system meet the refrigeration demand of refrigerator room, ensure that the uniformity of refrigerator room temperature.
In conclusion the control method of the refrigerating system of the embodiment of the present invention, is in advance refrigerating system setting setting quantity
Block form air door, the quantity of air door can be two or more, and each air door can be independently controlled it and open or close,
When specific control refrigerating system, the real time temperature of refrigerator room, then determines real time temperature and sets first in acquisition refrigerating system
The temperature difference between fixed refrigeration shutdown temperature, finally obtains target temperature range locating for the temperature difference, and then according to target temperature model
It encloses, determines the first quantity of the air door that refrigerating system needs to open, and control unlatching and the consistent air door of the first quantity.As a result,
This method determines the unlatching number of air door according to the temperature difference between the real time temperature of refrigerator room and the refrigeration shutdown temperature of setting
Amount, and accordingly the revolving speed of adjustment freezing blower makes cold air be evenly distributed on refrigeration to adjust refrigerating speed according to refrigeration demand
Compartment ensure that refrigerator room heat exchange sufficiently, reduce the temperature difference after freezing in refrigerator room between different location, improve cold
Hide the uniformity of cooling system.
Based on the above embodiment, after control opens the air door of the first quantity and adjusts the revolving speed of freezing blower, refrigerator
