To Study Different Losses and Loss Co-Efficient on Solar Flat Plate Collector at 900 Yaw Angle

Abstract:

The flat plate collector is a device used for harnessing the solar energy. The efficiency of this device is dependent on the various heat losses. These losses are bottom loss, side loss, edge loss, corner loss, sealing loss & top loss. These losses are measured as well as recorded. There are forty eight thermocouples located at different points. The input energy is through the electric heaters to the collector. These heaters are kept below the absorber. The capacity of each heater is 0.5 kW. These heaters are two in number. The wind velocity is measured by the vane type anemometer. The input heat flux is kept constant & wind velocity is varied. The evaluation of various heat losses is important for the performance evaluation of the collector. Generally the upward heat losses play an important role in the total heat losses. The present paper is an experimental simulation of a horizontal single glazed flat plate collector. The losses are measured under steady state conditions at different wind velocity & keeping 90⁰ yaw angle and at zero tilt angle.
