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 i
s 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.
