2. Automatic temperaturecontrol
Automatic temperature control under varied ambient temperature
conditions for anoptimizedcoolingachievement
3. Application of inverter technology
Theadvancedinverter technologyis appliedforintegrationofnoise
reduction andsuper freezing.Working frequencyof the compressor is
automaticallyadjusted with thevariation of ambient temperature.
Unique inverter operation:Therefrigerator can beset automaticallyfor
lowspeed and lownoiseoperationat night.
4. Energy-efficiency
Thick heat insulationisused to minimizetemperature gain and to
optimize thecooling system for themost efficient coolingresult.

2 BriefDescription ofSystem FlowChart
The refrigeratingsystem of directcoolingthree-system refrigerator
belongsto the categoryof three circulatingsystem. It isformedby adding
another 3-waysolenoid valve andacapillaryto adouble-system. Wecan
control the twovalves to make refrigerant gothrough differentlines.For
example, 1->2->3->4->5->6->7->9 、1->2->3->4->5->6->8->9 or
1->2->3->4->5->9.
Whentherefrigerator is just powered on, the refrigerant flowsthrough
the adjusttemperature compartmentevaporatorsandfreezer
compartmentevaporators. Afterthe adjust temperature compartment
temperaturehas reachedtherequired value,thesolenoidvalveis
energized, thus causetherefrigerant toflowthroughtheRefrigerator
Compartment evaporators、freezercompartment evaporatorsor soft freezer
compartment evaporators.
