Abstract:
Conventional energy sources through-out the world are soon going to be exhausted.
Millennium Development Goal (MDG) by United Nation (UN) vision and aim now reflects upon
numerous attempt and experiment conduction on different methods to harness energy from
renewable sources which are more sustainable. This thesis work is a contribution to that
purpose.
The technique that has been experimented on uses a closed insulated conduit with glazed
through transparent glass medium. Basic theory of solar radiation and heat convection in water
(working fluid) has been combined with heat conduction process by using copper tubes and
aluminum absorber plate. Insulated materials, thermal reservoir are used for better result
output.
By this experimental conduction, we have achieved a temperature difference of 33*C which is
of 56.79% efficiency range. The obtained data and experimental findings are validated with the
literature theoretical assumptions and experimental demonstration. Both show a cost effective
and simple form of heat energy extraction for space heating/power generation use which has
been thoroughly discussed with comparison. The result parameters also reflect upon
considerable prospect of uses and recommend valid ways to increase efficiency improvising
more acceptable energy conversion form.
This is the most cost effective and less complicated method of solar thermal energy harnessing
which is also eco-friendly. Under-developed and developing countries can take this work as an
illustration for renewable energy utilization for sustainable energy prospect.
