Formula.
Step 20, the temperature-sensing probe 17 continuously detect the temperature T in the freezerinAnd liquid level induction system 16 connects
Liquid level V in continuous detection first fluid reservoir 6in, work as TinAt 0 DEG C of >, into the pre-cooling refrigeration cycle, the temperature-sensitive is visited
First 17 give 18 1 signal instruction of controller, and the controller 18 opens the compressor 1, first electromagnetic valve 1, institute
State second solenoid valve door 8 and the third electromagnetic valve 9, it is the 4th electromagnetic valve 11, the 5th electromagnetic valve 12, described
6th electromagnetic valve 14, the compressor 1 are drawn the refrigerant vapour of the low-temp low-pressure in second fluid reservoir 13, are compressed into
After the refrigerant vapour of high temperature and pressure, after the condenser 2 heat dissipation is condensed into medium temperature high pressure refrigerant liquid, through described first
After the throttling of throttle valve 4 is the refrigerant liquid of low-temp low-pressure, enter first fluid reservoir 6, a part system through the first solenoid valve 5
Again after the second throttle 7 throttling, the refrigerant liquid of low-temp low-pressure enters described cryogen liquid after second solenoid valve 8
Bright dress evaporator 15, which absorbs heat, in freezer is vaporized into the refrigerant vapour of low-temp low-pressure, then enters described the through third solenoid valve 9
Two fluid reservoirs 13；Another part refrigerant liquid again through the third throttle valve 10 throttling after, after the 4th solenoid valve 11, low temperature
The refrigerant liquid of low pressure enters the refrigerant vapour that the freezer wall concealed installation evaporator 19 heat absorption is vaporized into low-temp low-pressure,
Enter second fluid reservoir 13 after the 5th solenoid valve 12, is sucked again by the compressor 1 after the 6th solenoid valve 14, repeatedly
Circulation；At this point, the temperature T in the freezerinConstantly decline, as the temperature T in the freezerin≤ -5 DEG C, controller 18
The 4th solenoid valve 11 and the 5th solenoid valve 12 of the inlet and outlet of third throttle valve 10 and freezer wall concealed installation evaporator 19 are closed,
Only has some refrigerant liquid in refrigerant liquid in first fluid reservoir 6 again after the second throttle 7 throttling, low temperature is low
The refrigerant liquid of pressure enters bright dress evaporator 15 heat absorption in the freezer after second solenoid valve 8 and is vaporized into low-temp low-pressure
Refrigerant vapour, then enter second fluid reservoir 13 through third solenoid valve 9；And it is stored in the amount in first fluid reservoir 6
It is more, so that the liquid level V in first fluid reservoir 6 inConstantly rise, until the temperature-sensing probe detects the refrigeration
Temperature T in libraryin ≤ -18 DEG C and liquid level induction system 16 detect the liquid level V in first fluid reservoir 6 inMeet range
0.5V < V inWhen < 0.9V, 30 are entered step；
Step 30, the uncompressed mechanism cold circulation pattern.The temperature-sensing probe 17 gives 18 1 signal instruction of controller, institute
It states controller 18 and closes the compressor 1, the first solenoid valve 5, the first throttle valve 4, the second throttle 7 and freezer
Second solenoid valve 8, third solenoid valve 9 and the 6th solenoid valve 14 that interior bright dress evaporator 15 is imported and exported, open third throttle valve
10 and freezer wall concealed installation evaporator 19 inlet and outlet the 4th solenoid valve 11, the 5th solenoid valve 12, first fluid reservoir 6
