Capillary Tube(s) (Figure 4-4)
The high-pressure warm liquid refrigerant travels
through the long skinny capillary tube which is soldered
to the suction tube (these two tubes soldered together
create the heat exchanger). As the warm liquid refriger-
ant travels through the capillary tube it gives up heat to
the cool refrigerant gas traveling through the suction
tube and the pressure drops, so it is a low-pressure/-
cool liquid before it enters the evaporator.
Evaporator(s) (Figure 4-5)
As the low-pressure/cool liquid refrigerant enters the
evaporator, it vaporizes. This is caused by a dramatic
pressure change, occurring when the refrigerant from
the smaller diameter capillary tubing enters the larger
diameter evaporator tubing. This refrigerant vapor trav-
els through the evaporator, absorbing heat from the
compartment, gradually converting the refrigerant to a
cool gas. This cool refrigerant gas then enters the suc-
tion tube.
Suction Tube(s) & Heat Exchanger(s)
The cool gas travels through the suction tube which is
soldered to the capillary tube (as mentioned earlier,
these two tubes soldered together create the heat
exchanger). As this cool refrigerant gas travels through
the suction tube it absorbs heat from the warm liquid
refrigerant traveling through the capillary tube, making it
a luke warm gas. (There is a suction tube "T" connec-
tion that diverts the two separate suction tubes from the
evaporators to one suction tube that enters the com-
pressor.) The lukewarm refrigerant gas is pulled back
to the compressor (via vacuum force), where the
process begins again.
