Lubricationg
Oils
for
R410A
As
the
lubricating
oils
for
R22,
mineral
oils,
alkylbenze
synthetic
oils,
etc.
have
so
far
been
used.
As
R410A
features
less
solubility
with
these
conventional
lubricating
oils
such
as
mineral
oils,
the
lubricating
oils
tend
to
stay
within
the
refrigeration
cycle.
As
the
lubricating
oils
highly
soluble
with
R410A,
ester,
ethereal
and
other
synthetic
oils
are
available.
However,
as
these
synthetic
oils
are
very
hygroscopic,
they
must
be
treated
even
more
carefully
than
the
conventional
lubricating
oils.
Furthermore,
if
these
synthetic
oils
are
mixed
with
mineral
oils,
alkylbenzene
synthetic
oils,
etc.,
they
may
deteriorate,
and
block
the
capillary
tubes,
or
cause
the
compressor
to
fail.
So,
never
mix
these
synthetic
oils.
1.2
Safety
during
Installation/Servicing
As
R410A's
pressure
is
about
1.6
times
higher
than
that
of
R22,
improper
installation/servicing
may
cause
a
serious
trouble.
By
using
tools
and
materials
exclusive
for
R410A,
it
is
necessary
to
carry
out
installation/servicing
safely
while
taking
the
following
precautions
into
consideration.
1)
Never
use
refrigerant
other
than
R410A
in
an
air
conditioner
which
is
designed
to
operate
with
R410A.
2)
Ifa
refrigeration
gas
leakage
occurs
during
installation/servicing,
be
sure
to
ventilate
fully.
If
the
refrigerant
gas
comes
into
contact
with
fire,
a
poisonous
gas
may
occur.
3)
When
installing
or
removing
an
air
conditioner,
do
not
allow
air
or
moisture
to
remain
in
the
refrigeration
cycle.
Otherwise,
pressure
in
the
refrigeration
cycle
may
become
abnormally
high
so
that
a
rupture
or
personal
injury
may
be
caused.
4)
After
completion
of
installation
work,
check
to
make
sure
that
there
is
no
refrigeration
gas
leakage.
If
the
refrigerant
gas
leaks
into
the
room,
coming
into
contact
with
fire
in
the
fandriven
heater,
space
heater,
etc.,
a
poisonous
gas
may
occur.
5)
When
an
air
conditioning
system
charged
with
a
large
volume
of
refrigerant
(e.
g.
multi
type
air
conditioner)
is
installed
in
a
small
room,
it
is
necessary
to
exercise
care
so
that,
even
when
refrigerant
leaks,
its
concentration
does
not
exceed
the
marginal
level.
If
teh
refrigerant
gas
leakage
occurs
and
its
concentration
exceeds
the
marginal
level,
an
oxygen
starvation
accident
may
result.
6)
Be
sure
to
carry
out
installation
or
removal
according
to
the
installation
manual.
Improper
installation
may
cause
refrigeration
troule,
water
leakage,
electric
shock,
fire,
etc.
7)
Unauthorized
modifications
to
the
air
conditioner
may
be
dangerous.
If
a
breakdown
occurs
please
call
a
qualified
air
conditioner
technician
or
electrician.
Improper
repair's
may
result
in
water
leakage,
electric
shock
and
file,
etc.
Refrigerant
Piping
Installation
Piping
Materials
and
Joints
Used
For
the
refrigerant
piping
installation,
copper
pipes
and
joints
are
mainly
used.
Copper
pipes
and
joints
suitable
for
the
refrigerant
must
be
chosen
and
installed.
Furthermore,
it
is
necessary
to
use
clean
copper
pipes
and
joints
whose
interior
surfaces
are
less
affected
by
contaminants.
(1)
Copper
Pipes
It
is
necessary
to
use
seamless
copper
pipes
which
are
made
of
either
copper
or
copper
alloy
and
it
is
desirable
that
the
amount
of
residual
oil
is
less
than
40
mg/10m.
Do
not
use
copper
pipes
having
a
collapsed,
deformed
or
discolored
portion
(especially
on
the
interior
surface).
Otherwise,
the
expansion
valve
or
capillary
tube
may
become
blocked
with
contaminants.
As
an
air
conditioner
using
R410A
incurs
pressure
higher
than
when
using
R22,
it
is
necessary
to
choose
adequate
materials.
Thicknesses
of
copper
pipes
used
with
R410A
are
as
shown
in
Table
3.
Never
use
copper
pipes
thinner
than
0.8
mm
even
when
it
is
available
on
the
market.
