Schematic Diagram of Free Match Series Inverter Heat Pump System
The
outdoor
and
indoor
units
start
to
work
once
the
power
is
switched
on.
During
the
cooling
operation,
the
low
temperature,
low
pressure
refrigerant
gas
from
the
heat
exchanger
of
each
indoor
unit
gets
together
and
then
is
taken
into
the
compressor
to
be
compressed
into
high
temperature,
high
pressure
gas,
which
will
soon
go
to
the
heat
exchanger
of
the
outdoor
unit
to
exchange
heat
with
the
outdoor
air
and
then
is
turned
into
refrigerant
liquid.
After
passing
through
the
throttling
device,
the
temperature
and
pressure
of
the
refrigerant
liquid will further decrease and then go the main valve. After that, it will be divided and go to the heat exchanger
of
each
indoor
unit
to
exchange
heat
with
the
air
which
needs
to
be
conditioned.
Consequently,
the
refrigerant
liquid
become
low
temperature,
low
pressure
refrigerant
gas
again.
Such
a
refrigeration
cycle
goes
round
and
round
to
achieve
the
desired
refrigeration
purpose.
During
the
heating
operation,
the
four-way
valve
is
involved
to
make
the
refrigeration
cycle
run
reverse.
The
refrigerant
radiates
heat
in
the
heat
exchanger
of
the
indoor
unit
a
nd
absorb
s
heat
in
the
heat
exchanger
of
the
outdoor
unit
for
a
heat
pump heating cycle so as to
achieve the desired heating
function
.
