 Parts and Functions  
						

							8  Function Schedule 
 
1. Three cooling system 
 
There are three separate cooling parts in the refrigerator — refrigerator、
freezer and soft freezer.seperately 
 
2. Automatic temperature control 
 
Automatic temperature control under varied ambient temperature 
conditions for an optimized cooling achievement 
 
3. Application of inverter technology 
 
The advanced inverter technology is applied for integration of noise 
reduction and super freezing. Working frequency of the compressor is 
automatically adjusted with the variation of ambient temperature. 
Unique inverter operation: The refrigerator can be set automatically for 
low speed and low noise operation at night. 
 
4. Energy-efficiency 
 
Thick heat insulation is used to minimize temperature gain and to 
optimize the cooling system for the most efficient cooling result. 
 
5. VFD display 
 
Application of VFD technology for display of the refrigerator operation 
status and temperatures in refrigerator、freezer and soft freezer. 
 
6. Over temp warning 
 
The warning function is activated when freezer temperature exceeds the 
set temperature value. 
 
7. Crisper with adjustable moisture 
 
Moisture in the crisper can be adjusted for satisfaction of vegetables and 
fruits storage

2 Brief Description of System Flow Chart 
 
  The refrigerating system of direct cooling three-system refrigerator 
belongs to the category of three circulating system. It is formed by adding 
another  3-way solenoid valve and a capillary to a double-system. We can 
control the two valves to make refrigerant go through different lines.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. 
  When the refrigerator is just powered on, the refrigerant flows through  
the  adjust temperature compartment evaporators  and freezer 
compartment evaporators. After the adjust temperature compartment 
temperature has reached the required value, the solenoid valve is 
energized, thus cause the refrigerant to flow through the Refrigerator 
Compartment evaporators、freezer compartment evaporators or soft freezer 
compartment evaporators.
