Symptom Direct cause Root cause Action
06 Unusually
high
pressure
(abnormal
discharge
pressure)
Heat exchange
failure in condenser
(heat exchanger)
Failure or water
dripping in fan
motor, thermo
switch, water
spraying pipes,
cooling water
pumps, etc.
Identify defective devices,
investigate causes of failure and
take necessary actions.
Then, replace failed device(s).
Faulty adjustment
of cooling
water/brine
In case of manually adjusted valve,
readjust the valve.
When an automatic control valve
(including wax valve) is used,
investigate the cause and take
necessary actions.
Other causes of
insufficient flow of
cooling water, etc.
Inspect filters installed on the
circulation route for clogging and
contamination, and take necessary
actions.
Inspect for leaks in circulation
routes, and take necessary actions.
Inspect water supply
routes/mechanisms, and take
necessary actions.
If frozen, take measures such as
improvement of heat insulation or
increase of temperature.
Deficiency in heat
exchanger
performance
If the symptom is caused by change
in operating conditions, re-examine
the conditions for improvement.
If the symptom is caused by change
in installation environment, improve
the environment if possible.
In either case, if improvement
measure is difficult to be made, add
more heat exchangers or increase
their sizes.
Non-condensable
gases mixed into
the system
Leak on low
pressure side
* There are also
cases where the
symptom was
caused by
corrosion in
suction
temperature
gauge protection
Perform a leak check, and take
necessary measures.
Air-purge the heat exchanger.
Refrigerant is
excessive.
In some cases,
insufficient cooling
is judged as caused
by insufficient
refrigerant and, as
a result, refrigerant
is charged
repeatedly.
Properly adjust the refrigerant
charge.
Capacity of heat
changer is
insufficient.
If the symptom is caused by change
in operating conditions, re-examine
the conditions for improvement.
If improvement is difficult, add heat
exchangers or increase their sizes.
