Résumé

In most of the Automotive Air Conditioning Systems (AACSs) though the compressor is powered by the car engine, the evaporator blower and the condenser fan are run by a 12-volt DC battery which is powered by an alternator. Any fault in the alternator, drops the battery output voltage. Owing to this, a stationary test rig for an AACS is developed with all actual automotive components. A continuous monitoring of the system performance is done at different battery charge level. It is observed that the evaporator blower and the condenser fan speed reduces continuously with the discharging of the storage battery, resulting a certain drop in air flow rate across the heat exchangers. Here, the continuous monitoring of the battery discharge voltage and its impact on the deterioration on the system cooling capacity, compression work, and the COP are reported.
