7. Working principle
The cooling unit applies the theory of phase-transition cooling this way: the gaseous refrigerant
is expelled out of the compressor
,
in high temperature and high pressure
,
enters into
condenser
，
cooled forcibly and liquefied in modest temperature and still high pressure
，
then
goes through the throttling devices such as capillary or expansion valve to become liquid in
lower temperature and lower pressure when it flows into evaporator
，
afterwards
，
it returns
to the condenser by phasechange absorbing the heat of inside enclosure. This reciprocating
circulation guarantees the reliable working environment.
8. Maintenance/care
As
the
maintenance
-
free
cooling
device
，
the
unit
has
been
strictly
tested
before
ex
.
Factory and

.
The
fan
of
ball
bearing
has
a
lifespan
up to
30
，
000
hour
.
The
filter
mesh
is
recommended
to
use
in
case
of
dense
dusts
and
clean
at
twice every
month
.
Turn
off
the
power
if
the
cooling
unit
is
kept
long
not
for
use
.
The
power
must
be
switched
off
in
the
period
of
maintenance
/
care
.
9. Quality warranty
