Abstract
Experimental analysis of solar water heater with compound parabolic concentrator
Highlights
Solar energy is one form of non-conventional energy which is available free of cost and the simplest way of harnessing it is by directly converting it into useful thermal energy
The above graph shows a maximum of 68% efficiency for Compound parabolic concentrator (CPC) whereas 54% and 43% for V trough and Flat plate respectively
The following conclusions from the present experimental work can be made: 1. From the graphs, it is clear that the highest efficiency is obtained in the CPC collector and from the V trough and lastly from the flat plate
Summary
Solar energy is one form of non-conventional energy which is available free of cost and the simplest way of harnessing it is by directly converting it into useful thermal energy. A typical device that does the above conversion is a solar water heater (SWH). It heats up the heat transfer fluid such as water, non-freezing liquid or air for domestic usage [1]. Domestic water heating comprises 80-90% of heating load in India [2]. By using the sun as an energy source which is both renewable and free, we can cut the heating expenses by a large amount [3]. An extensive research has been done in the past [4,5,6,7,8,9,10] for SWH which depicts the deeper findings on the performance analysis of concentrating parabolic trough
