Design and Fabrication of Solar Air Heater with Aluminum Tubes.

      Аннотация: Energy demand is one of the most threatening problems arising now days. This can be resolved by usage of renewable energy resources. Solar energy is an ultimate renewable energy resource that nature has offered. Solar energy is nothing but the heat energy, light energy and radiation coming from the Sun. This solar energy is used in numerous heating and electrical applications. Solar air heater is a solar thermal technology in which the radiation from the sun is captured by an absorbing medium and used to heat air. The part of the research carried out involves in fabrication of solar air heater using Aluminum tubes as absorber medium and Rockwool for insulation. By considering mass flow rate of air through the Aluminum tubes using blower as input. In this project, the energy gain by the absorber and efficiencies are calculated by keeping constant mass flow rate, at different times of the given day.
