torque

keeps
the
fan
speed
at
2
900
rpm
rated
or
below
to
conserve
horsepower
at
high
engine
speed
It
also
helps
reduce
fan
noise
to
a
minimum
during
high

opera
tion
This
unit
is
filled
with
a
special
silicone
oil
used
as
a
fluid
coupling
which
controls
the
fan

Silicone

can
not

Tem
coupling
is
a
type
of
fan
coupling
which
is
provided
with
a
temperature
control
system
The
conventional
coupling
always
slips
the
fan
at
a
high
speed
under
a
constant
ratio
regardless
of
the
engine
cooling
requirement
The
slipping
ratio
of
the
Tem
coupling
however
is
properly
changed
with
the
cooling
requirement
ON
denotes
that
cooling
is
required
and
the
fan
operates
up
to
about
2
900rpm
When
high
cooling
is
not
required
during
cold
season
with
the
engine
warmed
up
etc
the
oper
ation
is
placed
under
OFF
condition
and
the
fan
slips
at
about
2
050
rpm
The
coiled
bimetal
thermostat
installed
on
the
front
center
portion
of
the
Tem
coupling
detects
temperature
of
air
passing
through
the
radiator
The
air
temperature
is
directly
relative
to
the
engine
coolant
tempera
ture
and
the
inside
slide
valve
is
opened
or
closed
as
required
and
thus
the
ON
OFF
control
is
performed
When
the
air
temperature
rises
the
bimetal
is
expanded
and
the
valve
is
opened
silicone
oil
is
forwarded
to
the
groove
that
transmits

the

is

When

REFRIGERATION

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

rating
liquid
such
as
alcohol
is
placed
in
a
container
inside
a
box
the

Air

perature
inside
the
box
will
drop
This
is
because
the
alcohol
is
evaporated
absorbing
the
heat
from
the

inside
the
box
If
the
gaseous
alcohol
is
collected
and
cooled

it

RECEIVER
DRIER
The
receiver
drier
rves
the
pur
pose
of
storing
tl
e
liquid
refrigerant
The
amount
of
the
liquid
refrigerant
flowing
through
the
system
varies
with
the
operating
condition
of
the
air
conditioner
To
be
accurate
the
receiver
drier
stores
excess
amount
of
refrigerant
when
the
heat
load
is
low
ered
It
also
releases
stored
refrigerant
when
additional
cooling
is
needed
thus
maintaining
the
optimum
flow
of
refrigerant
within
the
system
The
receiver
drier
includes
a
strain
er
and
desiccant
They
have
the
job
of
removing
moisture
and
foreign
parti
cles
as
the
refrigerant
circulates
within
the
system
The
pressure
relief
valve
is
installed
beside
the
sight
glass
of
the
receiver
drier
The
purpose
of
the
valve
is
to
release
preSsurized
refrigerant
vapor
into
the
atmosphere
in
the
event
of
excessive
pressure
build
up
in
the
high
pressure
line
The
pressure
relief
valve
opens
automatically
at
a
pressure
of
about
38
kg
cm2
540
psi
EXPANSION
VALVE
The
expansion
valve
restricts
the
flow
of
liquid
refrigerant
as
it
passes
through
it
and
delivers
sprayed
refrig
erant
to
the
evaporator
for
faCilitating
refrigerant
evaporation
The
refrigerani
within
the
sensing
bulb
changes
in
pressure
through
the
super
heat
condit
ion
of
vaporized
re
frigerant
gas
which
comes
out
of
the
evaporator
causing
the
deflection
of
the
diaphragm
The
lift
of
the
ball
valve
attached
to
the
diaphragm
is
changed
by
the
deflection
of
the
dia
phragm
thus
controlling
the
amount
of
refrigerant
passing
the
orifice

ACTUATOR
The

is
actuated
by
the
intake
vacuum
or
the
atmospheric
air
introduced
by
turning
on
or
off
the
vacuum
switch
thereby
opening
or
closing

The
intake
port
for
atmospheric
air
is
located
on
the
vacuum
switch
The
check
valve
is
a
one
way
valve
and
it
prevents
negative
pressure
from
passing
through
it
except
when
the
pressure
at
the
actuator
side
is
higher
than
at
the
intake
manifold
side
thus
eliminating
the
variation
in
opening
or
closing
the

door
