Abstract :
Air conditioning system aims to control temperature, air flow and inertia in
the aircraft cabin, so the passanger feels comfortable when the airplane is in the air.
Basically, the principle of air conditioning system is transferring heat from a high
temperature system to a low temperature. There is a difference in temperature in
pack 1 and pack 2 that enter the cabin, which is caused by a condenser fault or crack
in one of the packs. That causes a significant temperature difference.
To overcome the High Difference Temperature, Troubleshoot is performed
according to TSM (Trouble Shooting Manual) which indicates Condensor Fault.
This failure can be seen on the ECAM at the time of the leak check, the ECAM
shows a message that a condensor fault has occurred. Condensor fault is caused by
internal and external factors. Internal factors such as components that are not
unserviceable, and external factors caused by foreign objects that can damage the
condensor itself.
After Troubleshooting the Condensor, checking and retesting are done for
15 minutes and monitor the ECAM display. If the temperature tends to be the same
or equal and no message appears on ECAM about high difference in pack discharge
temperature (Condensor fault), the test is successful and the air conditioning is
good.
