And for example application number is 03126145.0, and name is called the control method of refrigerator temperature, and it carries out according to the following steps: refrigerating chamber duty is divided into the startup-shutdown temperature range of more than three or three by A., and each startup-shutdown temperature range corresponds to an operation range; B. to the sampling of refrigeration indoor environment temperature, this probe temperature is sent to refrigerator main control chip; C. refrigerator main control chip is by reading probe temperature, and the startup-shutdown temperature corresponding according to the gear of actual set carries out break-make control to current compressor and magnetic valve.Owing to directly using certain temperature spot of refrigerating chamber box house whether to freeze to control refrigerating chamber, the actual temperature of refrigerating chamber box house can be reflected more accurately, namely to the Actual Control Effect of Strong of refrigerator, make the food of storage have longer memory time.In addition, whether use certain temperature spot of refrigerating chamber box house to control refrigerating chamber and freeze, the range of temperature of sensor proximity is little (0 DEG C-10 DEG C), is conducive to the selection of sensor.Compartment temperature is divided into three intervals by this patent, and adopts different countermeasures.
For another example application number is 200310118305.4; name is called the temperature-controlled process of refrigerator; control method comprises: first step; the detected temperatures of refrigerating chamber and refrigerating chamber upper limit design temperature and refrigerating chamber lower limit set temperature are compared; and make compressor and circulating fan start/close, make the scope between the detected temperatures arrival refrigerating chamber upper limit design temperature of refrigerating chamber and lower limit set temperature; Second step; after the first step; the detected temperatures of refrigerating chamber and refrigerating chamber upper limit design temperature and refrigerating chamber lower limit set temperature are compared; and make damper and circulating fan start/close, make the scope between the detected temperatures arrival refrigerating chamber upper limit design temperature of refrigerating chamber and lower limit set temperature; And third step, if compressor and circulating fan start in a first step, damper is airtight in the second step, then make cold air drainage at least one space in multiple refrigerating spaces of refrigerating chamber.This patent mainly compares the bound of pickup temperature and design temperature.
The mainly deterministic control method that above-mentioned refrigerator control system adopts, namely a certain index is judged (such as, temperature, humidity, time etc.) whether reach setting value, or divide between different cog regions to index of correlation, then next step workflow (such as, switch compressor, blower fan, defrost etc.) is started.And although deterministic determination methods directly can describe the difference of pickup temperature and design temperature, the approaching degree that can not describe out pickup temperature and design temperature (e.g., is picked up temperature and is differed with design temperature, 1
oc, 3
oc, 5
othe concrete difference such as C).And in refrigerator refrigeration system temperature controls, the approaching degree according to pickup temperature and design temperature adopts corresponding strategy, can improve compartment temperature accurately controls, and accomplishes that self-adaptive temperature controls, and plays the object promoting refrigeration for refrigerator ability, reduce energy consumption simultaneously.
