Rotating speed be 2100rpm), 8.5V (rotating speed of wind turbine 50 is 2000rpm) and 7.5V (rotating speed of wind turbine 50 is 1900rpm).
That is, during refrigeration system 30 is opened, control unit 80 controls wind turbine 50 and is held according to current preset rotating speed
Reforwarding turns, and when control unit 80 judges that the temperature of refrigerating chamber 20 reaches preset refrigerating temperature, control refrigeration system 30 is closed, and
Judge whether the temperature of freezing chamber 10 when refrigeration system 30 is closed is less than default cryogenic temperature, if the temperature of freezing chamber 10 is less than
Default cryogenic temperature, the rotating speed that control unit 80 then controls wind turbine 50 reduces, such as is reduced since maximum speed, and is freezing
Wind turbine 50 is controlled system 30 is opened next time when with the rotation speed operation after reduction, in other words, when refrigeration system 30 is again turned on, is controlled
Unit 80 processed controls wind turbine 50 according to the rotation speed operation after reduction.Wherein, when the rotating speed of wind turbine 50 have been lowered to deep low gear (such as
When 1900rpm), control unit 80 then controls the rotation speed operation that wind turbine 50 maintains deep low gear.
According to one embodiment of present invention, control unit 80 is additionally operable to control wind turbine 50 in 30 down periods of refrigeration system
The opening time is preset in operation, wherein if the temperature of freezing chamber 10 is more than default cryogenic temperature, control when refrigeration system 30 is closed
The opening time that unit 80 then controls wind turbine 50 extends, and the opening time controlled after the operation extension of wind turbine 50 stops transporting later
Row；If the temperature of freezing chamber 10 is equal to default cryogenic temperature when refrigeration system 30 is closed, control unit 80 ifs, controls wind turbine 50
It is out of service in the refrigeration system down periods.
It should be noted that the opening time of predeterminable a variety of wind turbines 50, such as full cut-off (closing wind turbine 50), wind turbine 50
Opening time be, 2 minutes, 3 minutes, 4 minutes and 5 minutes.
That is, during refrigeration system 30 is opened, control unit 80 controls wind turbine 50 and is held according to current preset rotating speed
Reforwarding turns, and when control unit 80 judges that the temperature of refrigerating chamber 20 reaches preset refrigerating temperature, control refrigeration system 30 is closed, and
Judge whether the temperature of freezing chamber 10 when refrigeration system 30 is closed is greater than or equal to default cryogenic temperature, if the temperature of freezing chamber 10
Degree is more than default cryogenic temperature, and the opening time that control unit 80 then controls wind turbine 50 extends, such as from most short opening time (example
Such as 2min) start to extend, and control wind turbine 50 operation extend after opening time after it is out of service, in other words, control unit 80
Control wind turbine 50 continues to run with 2min after the closing of refrigeration system 30, and it is out of service to control after 2min wind turbine 50 again, if
The temperature of freezing chamber 10 is equal to default cryogenic temperature, and control unit 80 then controls wind turbine 50 and stops in 30 down periods of control system
Operation.Wherein, when the opening time after the extension of wind turbine 50 has extended to highest gear (such as 5min), control unit 80 is then
Opening time after the extension of control wind turbine 50 maintains highest gear.
Further, control unit 80 can control wind turbine 50 after refrigeration system 30 is closed 30 seconds according to the unlatching after extension
Time runs.
It should be understood that when, when refrigeration system 30 each time is closed, control unit 80 is required for according to freezing chamber 10
The wind turbine when opening time of wind turbine 50 and refrigeration system 30 are again turned under 30 halted state of temperature adjustment current refrigeration system
30 rotating speed, and when the opening time of wind turbine 50 reaching most high-grade, the control wind turbine 50 of control unit 80 remains most high-grade and opens
The time is opened, when the rotating speed of wind turbine 50 reaches deep low gear, control unit 80 controls the rotating speed that wind turbine 50 maintains deep low gear.
For example, when environment temperature is 32 DEG C, electricity operation on refrigerator, the unlatching of refrigeration system 30 is freezed, wind turbine
50 according to current rotating speed operating (in the present embodiment, just power on when, the initial value of current rotating speed can be most high-grade rotating speed
2300rpm), the first temperature detecting unit 60 detects the temperature of refrigerating chamber 20 and is sent to control unit 80, and control unit 80 is sentenced
Whether the temperature of disconnected refrigerating chamber 20 reaches preset refrigerating temperature, if the temperature of refrigerating chamber 20 is not up to preset refrigerating temperature,
Control unit 80 controls refrigeration system 30 and continues to freeze, if the temperature of refrigerating chamber 20 reaches preset refrigerating temperature, controls list
Member 80, which controls refrigeration system 30 and closes, stops refrigeration, at this point, the temperature that second temperature detection unit 70 detects freezing chamber 10 is concurrent
It send to control unit 80, control unit 80 judges the relationship between the temperature of freezing chamber 10 and default cryogenic temperature.
If the temperature of freezing chamber 10 is equal with default cryogenic temperature, control unit 80 controls wind turbine 50 in refrigeration system
30 down periods are out of service, and when being opened according to previous refrigeration system 30 when refrigeration system 30 is again turned on wind turbine 50 it is pre-
If rotating speed is run.
If the temperature of freezing chamber 10 is less than default cryogenic temperature, one can be extended on the basis of the current opening time
Time gear (in the present embodiment, the initial value of current opening time can be minimum time gear 0 minute), and in refrigeration system
30 close the first preset times after such as 30 seconds, and control unit 80 controls wind turbine 50 according to such as 2 points of opening time after extension
Clock operates, and control wind turbine 50 is out of service after the 2 minutes, so recycles, until the temperature of freezing chamber 10 reaches default freezing
Temperature, wherein if the opening time of wind turbine 50 reaches the longest opening time, control unit 80 ifs controls wind turbine 50 and maintains most
Big opening time operation.Wherein, turn when rotating speed of the wind turbine 50 when refrigeration system 30 is closed is opened with upper primary refrigeration system 30
Speed is identical.
If the temperature of freezing chamber 10 is more than default cryogenic temperature, control unit 80 controls the rotating speed of wind turbine 50 current
A rotating speed gear is reduced on the basis of rotating speed, such as the rotating speed of wind turbine 50 is reduced to 2200rpm, and under refrigeration system 30
Primary control wind turbine 50 of opening so recycles, according to the rotation speed operation after reduction until the temperature of freezing chamber 10 reaches default cold
Freeze temperature, wherein if the rotating speed of wind turbine 50 is reduced to minimum speed, control unit 80 ifs controls wind turbine 50 and maintains minimum speed
Operating.
