ENERGY SAVING IN ROOF-TOP PASSENGER VEHICLE AIR CONDITIONING SYSTEM
Abstract
A roof-top passenger vehicle air conditioning system is experimentally investigated. Measurements were taken during the experimental period at a time interval of one minute for a setpoint temperature of 23oC with internal heat loads of 0, 1 and 2 kW. The cabin temperature and the speed of the compressor were varied and the performance of the system, energy consumption and energy saving ware analyzed. This study demonstrated the application of the On/Off and Fuzzy Logic Controllers (FLC) for the reduction of energy consumption and for thermal comfort. The energy analysis indicates that FLC is better than the On/Off mode of control. The results also indicated that the proposed FLC can successfully maintain the cabin temperature at acceptable levels with significant energy saving.
