【 摘 要 】
Energy crisis is becoming a major problem in Pakistan. Renewable energy sources are used to overcome this crisis. This research is about to increase the efficiency of fin type solar water heater by modification of its surface properties. During this research work, solar water heater module is fabricated and the modification of surfaces by using bare surface, external surface coated with high conductivity paint and lead electroplating is studied and the efficiency of solar heater is observed. The temperature profile and the heat transferred is studied and it was found that paint coated surface is more efficient than bare surface, further surface electroplated with lead is more efficient than painted surface for the same ambient conditions. The average increase in the heat absorption for lead plated and paint coated surface was observed 28.57% and 10.79 % respectively.【 预 览 】
