Abstract
In the present study, a direct solar PV-driven air conditioning system is designed for medium electric bus (21 passengers). Passive design for energy conservation is carried out first by improving insulation and reduces cooling load by 54%. Active design by modification of air conditioner with inverter-type with high COP (4.0) further reduces the energy consumption from 5.2 kW to 1.5 kW, by 71% in total. If spot cooling is employed, the energy consumption is further reduced to 1.1 kW, about 78%. The present study also designs a novel stand-alone solar PV system with small battery which assure operation probability of air conditioner OPB>0.9 at solar radiation IT>400 W/m2. That is, solar PV will supply most of power to drive the air conditioning system.
