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.
