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

The
heat
of
the

irculated

by

is

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

is

compressed

The

The
heat
inside
the

passenger

compartment
is
absorbed

by
changing

the

refrigerant
from
a

liquid
to
a

gas

and

then

dissipated
to
the
outside

by
