Abstract

Humankind faces enormous challenges relating to energy
supply and ecological safety.  Heating
system is an essential part of homes in colder area, which needs a lot of
energy. In this work a solar air heating system is designed by using easily
accessible materials to heat the room. The adoption of low cost materials and
easy design  represents the novelties of
the proposed system as compare to the other commercial collectors.  This eco-friendly solar air heating system
consists of flat plate collector (FPC), battery, solar cell and fans.  FPC consists of transparent glass, absorbing
plate, insulating material and fluid (air). 
In this experiment flat plate collectors are used inclined vertically at
the angle of 45℃ near to the wall of the room which gives attractive
results.  The results were obtained from
south face located room. The time of solar heating is about 7-8 hours on the
daily bases and an average temperature difference obtained was about 12℃ as
compared with the same dimension reference room. Experimental results conclude
that this solar air heating system is able to heat the room in cold
seasons.  Hence the system making very
important contribution for the saving of fossil fuels and diminution of carbon
release on worldwide scale.
