REFRIGERATION
SYSTEM
If
you
were
to
paint
your
fmger
with alcohol
your
finger
would feel
cold This
is
because the
liquid
alcohol
takes heat away from
your
fmger
while
it
evaporates
If
a
quickly
evapo
rating liquid
such
u
alcohol
is

DESCRIPTION
in
a
container
inside
a
box the
tern
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

compartment is absorbed
by changing
the
refrigerant
from

to
a

and then
dissipated to

CONDENSER
The condenser
is
installed
to the
front of the radiator The heated and
compressed refrigerant
gu from the
compressor condenses
to
a
liquid
by
being cooled by
