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.
