REFRIGERATION

SYSTEM

If

you
were
to

paint
your
rmger

with
alcohol

your
finger
would
feel

cold
This
is

because
the

liquid
alcohol

takes
heat

away
from

your

rmger

while
it

evaporates
If

a

quickly
evapo

rating
liquid
such

as
alcohol
is

placed

in
a
container
inside
a
box
the
tern
Air

Conditioning

perature
inside
the
box

will

drop
This

is

because
the

alcohol
is

evaporated

absorbing
the
heat

from
the
air

inside

the
box

If
the

gaseous
alcohol
is

collected
and
cooled

with
cold
water

it

will
be

changed
back
into
a

liquid
by

absorption
of
its
heat

by
the
cold

water

EVAPORATOR

The
heat
of
the
inside
air
which

irculated

by

is

absorbed
by

COMPRESSOR

The

compressor
is
installed
to
the

side
of
the

engine
and
is
driven

by

crank

pulley
through
a
belt
The

refrig

erant

gas
leaving
the

evaporator
is

forced
out
to
the
condenser

by
com

pressor
and
the

low

pressure
refriger

ant

gas
is

compressed
to

and

high

temperature

The

R

The
heat
inside
the

passenger

compartment
is
absorbed

by
changing

the

refrigerant
from
a

liquid
to
a

gas

and

then

dissipated
to
the
outside

the

refrigerant

CONDENSER

The
condenser
is

installed
to
the

front
of
the
radiator
The
heated
and

compressed
refrigerant

gas
from
the

compressor
condenses
to
a

liquid
by

being
cooled

by
air

passing
between

the
fins
of
the
condenser

REFRIGERANT
R
12

The

refrigerant
used
in
the
air

conditioner
is

generally
called
Re

frigerant
12
R
12
No
other

refrig

erant
than
the
above

refrigerant
should

be
used

Note
Exercise

care
when

handling
re

frigerant
as
it
is

stored
under

high

pressure

COMPRESSOR
OIL

The

SUNISO
5GS

refrig
ration

lubricant
should
be
used
to
assure
the

successful

compressor
operation
Use

of
oils
other
than

recommended
or

mixing
of

the
oil
with

other
oils
would

cause
chemical
reaction

or
lead
to

lowered

viscosity
or

deficient
lubrica

tion

The
oil

absorbs
moisture

as
it
con

tacts
the
air

This

points
out
the
need

for

care
not
to

expose
it

to
atmos

phere
for

an
extended

period
of
time

MAINTENANCE

The

following
checks
and
main

tenance
are

especially
important
to
the

air
conditioner

I

Check

refrigerant
level

2
Check

refrigerant
leaks

3
Check

belt
for

proper

4

Even
in

the
off
season
turn
the

compressor
for
10
minutes

at
least

once
a
month

by

running
the

engine
at

1

500

SAFETY

PRECAUTIONS

WARNING

1
Since
direct
contact
of
the

liquid

refrigerant
with

your
skin

will

cause
frostbite

always
be
carelul

when

handling
the

refrigerant

Always
wear

goggles
to

protect

your

eyes
when

working
around

the

system

2
The

refrigerant
service
container

has
a
safe

strength
However
if

handled

incorrectly
it
will
ex

plode
Therelore

always
follow

the
instructions
On
the

label
In

particular
never
store
it
in
a
hot

location
above
520e

1260F

or

drop
it
from
a

high
height

3
The

refrigerant
gas
is
odorless

and
colorless
and

breathing

may

become
difficult
due
to
the
lack

of

oxygen
Since
the

relrigerant

gas
is
heavier
than
air
and

will

lay
close

to
the
floor

be

espe

cially
careful
when

handling
it
in

small
confined

spaces

4
The

refrigerant
itself

is
nonflam

mable
However

a
toxic

gas

phosgene
gas
is

produced
when

it

contacu
fire
and

special
care
is

therefore

required
when
check

ing
for

leaks
in
the

system
with
a

halide
torch

5
Do
not
steam
clean
On
the

sys

tem

especially
condenser
since

excessively
high
pressure
will

build

up
in
the

system
resulting

in

explosion
of
the

system

The

above

precautions
are
essen

tial

in

handling
of

Refrigerant

12
and
their
strict
observation

AC
9
requires
sufficient

training

Therefore
it
is
of
first

impor

tance
that

any
other

personnel

than
a
well
trained
serviceman

should
not
be

allowed
to
handle

the

refrigerant

EVACUATING
AND

CHARGING

SYSTEM

During

servicing
use
caution
to

keep
air

from

getting
into

refrigerant

When
air

enters
the

system
all

refriger

ant
must
be
evacuated

from

system

prior
to

charging
new

refrigerant
Air

in

refrigerant
has
the

following
delete

rious
effects

1
Since
the
condensation

tempera

ture
of

the
air
is

extremely
low
the
air

will
not

be
condensed
when

refrigerant

gas
is
condensed
in
the
condenser

and

the
air

will
thus
remain
in

gaseous

fonn

Consequently
the
effective

thermal
transmission
area
of
condenser

for

refrigerant
gas
will

be
reduced
and

refrigerant
gas
to
be

condensed
will

be

reduced
The

pressure
rise
will
become

proportional
to
the
volume

of
the
air

in

system

2
When
air
and

refrigerant
are

r
tixed
in

system
a

chemical
reaction

will
be

produced
and

hydrochloric

acid
which
will

adversely
affect
the

aluminum

copper
iron
and
other

materials
in

system
may
be

generated

HANDLING
MANIFOLD

GAUGE

The

pressure
at
the

high
and
low

sides
of

system
should
be
measured

when

evacuating
and

charging

refrig

erant
and
when

diagnosing
trouble
in

the

system
The
manifold

gauge
is
used

for
these

purposes
A

manifold

gauge

has
two

pressure

gauges
a
low

pressure

gauge
and
a

high
pressure

gauge
These

gauges
are

connected
to
the

high
and

low
side
service

valves
of

system

through
flexible

charging
hoses
The

of
