The sealed system uses a new, linear compressor to drive the
refrigeraon cycle.
Refrigerant is pumped through the condenser and a non-UV dye
drier to the three-way valve. The three-way valve aligns to allow
refrigerant to either the RC or FC evaporator, depending on which
is being cooled. A check valve is posioned at the outlet of the
FC Evaporator to prevent refrigerant back ow during RC cooling.
The linear compressor takes a sucon of the evaporator outlet of
the compartment being cooled.

Refrigerant ow has been updated to make the refrigerator more
ecient. The check valve that prevents refrigerant from one
evaporator to the other was eliminated.
While cooling the freezer secon, due to the low pressure in
the capillary tubing, the refrigerant will be in the evaporator of
refrigerator compartment but will not be owing through the
coil. The tubing was re-routed for the refrigerator evaporator to
go through the freezer evaporator to keep it cold then back the
compressor. The freezer fan does not run during this me.
