Method for operating a compressed air conditioning unit in a vehicle, compressed air conditioning unit with such a method, vehicle with such a compressed air conditioning unit and computer program product

The method involves using electronic system for controlling compressed air processing system, and compressed air reservoir for storing compressed air. The electronic unit for controlling air processing system during vehicle standstill is provided. Other electronic unit is operated in power saving mode and is activated in function of parameters such as measured temperature and/or humidity values, so that vehicle air pressure reduction through electronic unit for controlling air processing system directly and/or indirectly using controllable valve of another electronic unit is performed. Independent claims are included for the following: (1) compressed air treatment system; (2) vehicle; and (3) computer program product for operating compressed air system.
