3) There is air in the
liquid cycle system
4)Low working
efficiency of
compressor
5) There is something
that blocked the liquid
cycle system
2.NO COOL
(Popular failure reasons are below):
Reason
1) Leakage of gas
2)There is some thing
well.
Phenomenon of failure:
a, higher pressure of liquid cycle system
than norm.
b, higher temperature of condenser.
c, larger electric current of compressor
d, there maybe ice on the suction tube.
e, when gas is too much, some gas liquid
might goes back into compressor,
compressor will be damaged by liquid.
The air in system will cause lower efficiency
of cooling.
Phenomenon of failure:
a, higher pressure of liquid cycle system
than norm, but the pressure is not over the
limit.
b, higher temperature of discharging tube.
C, much noise
General when a compressor works for many
years, some parts of compressor were wear,
so that compressor discharge less gas out,
unit does not work strongly.
Phenomenon of failure:
a, lower pressure of discharging, check the
pressure of system with pressure meter to
see if it is normal.
b, higher temperature of compressor
surface.
C, cut off the discharging tube, to see if you
can block the gas coming out of the tube
when compressor is working.
Some time there is something blocked the
filter of liquid cycle system, so that unit is not
cold.
Phenomenon of failure:
a, lower pressure of discharging
b, lower temperature of discharging.
analysis
Phenomenon of failure:
a, leaking fast
b, leaking slowly
c, no voice of liquid flowing
d, cut off charging tube, no gas
goes out.
A, Ice blocking
finally sealed the system.
First stop unit for several minutes,
and then open charging tube,
discharge all of gas. Change a
new filter, and then recharge gas,
finally sealed the system.
Change a new compressor.
Change a new filter
Solutions:
First find out the point of leaking on tube,
and then sealed it, vacuuming it, finally
recharge with gas.
Note：
If you find oil on somewhere, it is possible
that leakage point is there.
First stop unit for several minutes, and then
