Experimental Investigation on the Performance of Parabolic Through Solar Collector with Magnifying Glasses
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
Now a day’s consumption of hot water is increased because of our modern life style for drinking, cooking, washing, bathing etc. For heating water, we are using non-renewable energy sources which cause damage to the environment. In this present work it is suggested to increase the temperature of water by using solar energy, which is available abundantly at free of cost. The device that increases the water temperature through solar heat energy source is known as ‘PARABOLIC SOLAR TROUGH COLLECTOR’. PTSC is a simple device that collects the solar radiation and focus on to copper pipe which is exactly located at the focal point of trough and their by increases the water temperature which is eco-friendly and economical. The performance of PTSC depends on the amount of rays reflected on to the copper pipe. Any attempt that improves the concentration of sun rays results in improvement of the performance of PTSC. In the present attempt it is proposed to analyze the performance of PSTV associated with magnifying lens which increases the feed water temperature and the effect of PTSC orientation and black coating on PTSC performance is analyzed. From this experiment it is obtained that the parabolic collector along with the magnifying glasses yields max output temperature and productivity. Orientation of the PTSC is suggested to position in 30o North towards West direction to obtain maximum productivity. When parabolic collector along with magnifying lens is placed at 30° north towards the West a maximum temperature difference obtained is 28°C by which performance is improved by 42.85% than without magnifying glasses. When parabolic collector with black coating on the copper pipe is placed at 30° north towards west a maximum temperature difference obtained is 17°C by which performance is improved by 5.88% than without black coating.
