Abstract
The performance of solar water heater varies depending upon many parameters, such as operating temperature, mass flow rate, solar insolation, collector orientations, solar time, wind conditions, ambient temperature, selectivity of the absorber surface, etc. A Linear Fresnel reflecting concentrator in a planar configuration using commercially available mirror strips of reflectivity approximately 0.7 in conjunction with a reverse flat plate selective and non-selective absorber surface has been designed and developed. The performance studies of the solar water heater-cum-steam cooker have been carried out. The efficiencies of the devices were found to be about 60% and 55% for selective and non-selective surfaces, respectively. This solar energy device can be made useful in the domestic sector by operating it year around in our solar insolation condition.
