Tfm goes to step S130 if Tf≤Tfm；Otherwise, step S140 is gone to.
For example, by between refrigerating chamber 100 and evaporator compartment use air cooling way freeze to refrigerating chamber 100 for into
Row explanation: as Tr > Trm, air-cooled circulation loop is formed between refrigerating chamber 100 and evaporator compartment, by evaporator compartment
Interior Cryogenic air is conveyed to refrigerating chamber 100, to reduce the temperature of refrigerating chamber 100.
It follows that in the present embodiment, by judging that the size of temperature Tf of freezing chamber 300 is air-cooled using which kind of to determine
Mode freezes to refrigerating chamber 100, not only can reach the purpose for delaying compressor start, but also will not be to the freezing of freezing chamber 300
Effect impacts, and reduces the energy consumption of wind cooling refrigerator to a greater extent.It should be noted that in wind cooling refrigerator use process
In, the temperature of real-time detection freezing chamber 300, but only by active blower 330 to refrigerating chamber 100 carry out temperature-compensating when,
The temperature of freezing chamber 300 is compared with the second preset temperature, in other cases, by the temperature and Tfk of freezing chamber 300
(turn-on temperature of freezing chamber 300) is compared, to ensure the normal operation of wind cooling refrigerator.
Step S130 opens active blower and second compartment electric flap；In this step, Tf≤Tfm, freezing chamber 300
Temperature meets the condition that temperature-compensating is carried out to refrigerating chamber 100, by starting active blower 330, and unlatching and 100 phase of refrigerating chamber
Corresponding refrigerator damper 421, to form the first active air-cooled circulation loop between refrigerating chamber 100 and evaporator compartment,
Under the driving of active blower 330, the Cryogenic air in evaporator compartment exists under the action of pressure difference via air-cooled circulation loop
It is circulated between refrigerating chamber 100 and evaporator compartment, during this, rear and evaporation of the circulating current in evaporator compartment
