6.6: Oil Trap

vals along the
V
ertical suction
pipe. This
is
espe-
cially so
when
the outdoor unit is located on a
higher elevation than the indoor unit. These oil
traps
help
to get any accumulated oil to move
upwards,
as
shown
in
Figure
2.1. The design of
the
traps
will
forcibly
cause the gaseous
refriger-
ant to
pass
through the oil thus, carrying it
upwards back to the compresso
r.
As a guideline, an oil tra
p
is required at every 1
