Border is low temperature environment, further obtains the temperature of cold compartment of refrigerator, judges whether temperature of refrigerating chamber is less than the second preset temperature, with
It is high load capacity or underload to determine the current casing load condition of refrigerator, when cold compartment of refrigerator is that temperature is default less than second warm
The current casing load condition of degree explanation refrigerator is underload, then control refrigerator opens the first preset mode, and the present invention is in ice
In the case that load is relatively low inside and outside case, the preset mode of unlatching first of refrigerator is controlled, the rotating speed of fan electromotor is reduced, can pass through
The means of one fixed input voltage from master regulation module regulation fan electromotor are set on refrigerator mainboard to adjust fan
The rotating speed of motor, the rotating speed of fan electromotor can also be adjusted by setting the means of fixed rotating speed gear, it is achieved thereby that
It can meet that compartment temperature demand and can evades the too high refrigerated storage temperature brought of fan motor rotational speed under low circumstance temperature low load condition
The problem of less than zero degree, refrigerator fan motor " rotating speed " frequency conversion function is reached, has improved user experience.
