What
role
does
the
sensor
play
in
the
air
compressor?
The
compressor
(compressor),
as
the
heart
of
the
refrigeration
system,
is
a
driven
fluid
machine
that
lifts
low-pressure
gas
into
high-pressure
gas.
The
low-temperature
and
low-pressure
refrigerant
gas
sucked
from
the
suction
pipe
is
compressed
by
the
rotation
of
the
motor
to
discharge
the
high-temperature
and
high-pressure
refrigerant
gas
to
the
exhaust
pipe
to
provide
power
for
the
refrigeration
cycle.
Thus,
a
refrigeration
cycle
of
compression
→
condensation
(exotherm)
→
expansion
→
evaporation
(heat
absorption)
is
realized.
The
compressor
is
divided
into
piston
compressor,
screw
compressor,
centrifugal
compressor,
linear
compressor
and
so
on.
During
the
work,
the
actual
responsibility
of
the
compressor
is
to
increase
the
pressure
and
increase
the
state
of
the
suction
pressure
to
the
state
of
the
exhaust
pressure.
Compression
ratio
is
a
technical
expression
of
pressure
difference,
which
means
the
absolute
pressure
on
the
high
pressure
side
divided
by
the
absolute
pressure
on
the
low
pressure
side.
The
compression
ratio
must
be
calculated
using
an
absolute
pressure
value.
In
order
to
avoid
making
the
calculated
value
of
the
compression
ratio
negative,
the
absolute
pressure
must
be
used
instead
of
the
gauge
pressure
when
calculating
the
pressure
ratio.
It
makes
sense
to
use
an
absolute
pressure
value
to
make
the
compression
ratio
calculation
a
positive
value.
Large
central
air
conditioning,
refrigeration
equipment,
in
order
to
achieve
automatic
control
of
the
machine,
the
lowest
energy
consumption
ratio,
the
operation
of
the
equipment
needs
to
be
fully
monitored,
such
as
temperature,
refrigeration
medium
pressure.
The
pressure
sensor
mainly
measures
the
pressure
of
the
refrigerating
medium
online
on
the
refrigerating
equipment,
and
transmits
the
pressure
to
the
control
system
of
the
main
machine
in
the
form
of
electrical
signals,
so
as
to
reflect
the
compression
operation
state
of
the
equipment,
to
realize
the
automatic
control
of
the
product,
and
to
reflect
the
consumption
of
the
equipment
as
soon
as
possible.
