purpose
of
a
refrigeration
system?
-

maintain
a
temperature.
Which
of
the
following
best
describes
the
areas
of
required
knowledge
for
operators
of
refrigeration
systems?
-
ANSBasic
physical
principles,
interpretation
of
information
from
temperature
and
pressure
gauges,
basic
operating
principles.
Mechanical
refrigeration
is
a
series
of
steps
that:
-
ANSMoves
heat
energy
from
a
space
or
object
to
an
area
where
it
can
do
no
harm.
Heat
energy
always
flows:
-
ANSFrom
an
object
at
a
higher
temperature
to
an
object
at
a
lower
temperature.
Sensible
heat:
-
ANSIs
heat
energy
that
causes
a
change
in
temperature
but
does
not
cause
a
change
of
state.
Latent
heat:
-
ANSIs
heat
energy
that
causes
a
change
of
state
but
does
not
cause
a
change
in
temperature.
Which
of
the
answers
below
is
an
example
of
heat
transfer
by
convection?
-
ANSWarm
air
moving
over
an
object.
How
does
the
refrigeration
technician/operator
know
what
the
conditions
are
within
a
refrigeration
system?
-
ANSBy
using
his
knowledge

to
evaluate
temperature
and
pressure
readings.

-
ANSRankine.
Which
of
the
following
is
used

ANSBritish
Thermal
Units
(BTUs)
When
calculating
the
BTUs
that
have
to
be
removed
to
cool
a
substance,
what
combination
of
the
following
is
used?
-
ANSPounds
of
substance,
temperature
difference,
specific
heat.
Latent
heat
of
vaporization
-
ANSIs
the
heat
energy
required
to
cause
a
liquid
to
become
a
vapor.
Pressure
is
a
measure
of
-
ANSThe
relationship
of
a
force
being
applied
over
a
given
area.
The
relationship
between
temperature
difference
and
heat
flow
is
-
ANSThe
greater
the
temperature
difference
the
more
rapid
the
heat
flows.
Specific
heat
-
ANSIs
greater
as
the
substance
requires
more
heat
energy
to
increase
temperature.
