(Many reasons might cause that cooling not enough good, as blow :)
Reason analysis Solutions
1) Leakage of Gas
If some gas leaked unit will work not well.
Phenomenon of failure:
a. lower pressure of liquid cycle system
b. high temperature of copper tube of
discharging gas, hand feels very hot.
C. much noise, sounds like “ZZZZZ”, comes
from outlet of capillary.
d. the temperature fell down very slowly.
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) The quantity of Gas is
too much
If too much Gas was charged into the cycle
system, the extra gas will occupy some space
of evaporator, so that the area of heat
exchange becomes less, unit will work not 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.
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.
3) There is air in the
liquid cycle system
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
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.
4)Low working
efficiency of
compressor
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.
Change a new compressor.
5) There is something
that blocked the liquid
cycle system
Some t ime there is something blocked the
filter of liquid cycle system, so that unit is not
cold.
Phenomenon of failure:
a, lower pressure of discharging
Change a new filter
