Performance of an automotive air conditioning system with the variation of state-of-charge of the storage battery.

Type of article: Article, IJR article

Summary

In an automotive air conditioning system (AACS), the evaporator blower and the condenser fan are powered by a DC power supply containing a storage battery. The unique mutual interaction between the battery and the AACS, when the battery is isolated from the external power supply, has been investigated experimentally. As the prime movers draw power, the charge level of the battery falls and in turn the speed of the prime movers drops continuously. This deteriorates the performance of the condenser and the evaporator. Besides, a Matlab/Simulink based model has been developed to study the characteristics of the said electromechanical system during the charging and discharging cycles of the battery. Steady state performance of the system has also been studied at different battery voltage to supplement the dynamic data. The study reveals the typical deterioration of the cooling capacity and the COP of the system during the gradual derating of the supply voltage.
