Description of obtained algorithm
So, using this algorithm of malfunctions discovering we can compose an order of system checking, namely, steps of inspection (diagnostics). These steps are:
1. Check internal cavity of air-to-air heat exchanger
2. Check correctness of tubes installation
3. Check fittings of air-cycle machine
4. Inspect noise suppression device housing for cracks
5. Inspect places of pipeline and other aggregates mounting
6. Check correctness of installation
List of abbreviations:
1. ACS - air conditioning system
2. AAHE - air-to-air heat exchanger
3. ACM - air-cycle machine
4. NSD - noise suppression device.
