Figure 5.11: Pipe support using trunking box
The f
ollowin
g t
abl
e gives recommendation for the
support spacing of
the copper pipes:
a. Pipe Material
However,
working
with
R-410A
refrigerant
will
require a stronger
pipe
material to
withstand
the higher
working
pressure.
Burst strength of at least
2400
psig
will
be
required.
In
view
of this, do not use the
softer refrigeration tubing and Type M pipes. It is recommended that Type L be used for R-410A.
Joining of
two
pipe
s can
be
done easily
by
brazing
with
a
copper
ller rod.
For
better
quality joint, a
rod
with 10
% silver may
be
used.
It
may also
be
necessary to
braze
the
copper
pipe
to a
brass
or steel
In such instances, brazing with 34% silver ller rods must be used (together with brazing ux).
r, for the
simple
reason that
people
may just
step
on th
pipes
and damage them.
However,
should there
be
a need to do so; some
kind
of must
be
given. An
example is to place the pipes into a box which is mounted (screwed) onto the
oor.
