5) There is something
that blocked the liquid
cycle system
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.
Change a new filter
2.NO COOL
(Popular failure reasons are below):
Reason analysis Solutions:
1) Leakage of gas
Phenomenon of failure:
a, leaking fast
b, leaking slowly
c, no voice of liquid flowing
d, cut off charging tube, no gas goes
out. 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.
2)There is some thing
that blocked the liquid
cycle system
A,Ice blocking
Sometime because unknown reason
water comes into liquid cycle
system, the capillary will be blocked
by water after unit runs for period of
time.
Phenomenon of failure:
The unit works well in the inception,
after period of time the ice appears
in the capillary and becomes more
and more, till blocks the hole of
capillary completely. In the moment
you can find the ice on the
evaporator defrosts. The noise of
liquid flow disappears. The pressure
of absorbing becomes negative.
The phenomenon above will appear
again and again.
The way to check ice blocking:
Warm the capillary with a hot towel,
after a while the ice in the capillary
melt, you can hear a sound of gas
flow comes from the capillary
abruptly. The pressure of absorbing
becomes higher. It is Ice blocking.
First stop unit for several minutes, and then
open charging tube, discharge all of gas. Blow
the cycle system with gas of nitrogen, and then
recharge Gas, finally sealed the system.
B, there is offal block the capillary
Phenomenon of failure:
If the capillary is blocked by
something such as offal etc., the
sound of liquid flow disappears. First stop unit for several minutes, and then
open charging tube, discharge all of gas. Blow
the cycle system with gas of nitrogen. Change
a new capillary and filter, and then recharge
Gas, finally sealed the system.
