The first step：Refrigerator, which is powered, to be run, the start-stop of a compartment master control compressor of refrigerator.
Second step：When T >=6 DEG C, compressor is powered operation, and refrigerator starts to freeze, and otherwise waits for after T reaches 6 DEG C, pressure
Contracting machine, which is powered, to be run.
3rd step：If refrigerator under compressor operating refrigerating state, when occurring re-powering after powering off, is held by second step
OK.
4th step：If refrigerator is under compressor operating refrigerating state, when not occurring powering-off state, T≤2 DEG C compressor
Shut down.
5th step：After compressor shutdown, when temperature recovery is to T >=4 DEG C, performed by the 3rd step.
Above-mentioned 4th step and the 5th step are the working conditions in refrigerator normal operation, if refrigerator occurs without power-off
Words, will be run by normal start-stop point temperature.
When the master control process plate of refrigerator detects that refrigerator re-powers operation, compartment temperature sensor observed temperature reaches
On default compartment temperature sensor during electric turn-on temperature, compressor start operation, when refrigerator is in normal operation, compartment sensing
When device observed temperature reaches compartment temperature sensor turn-on temperature, compressor start；Compartment temperature sensor observed temperature reaches
During compartment sensor shutdown temperature, compressor shutdown.
