Performance Evaluation Of Direct Absorption Solar Flat plate Collector Using Thermic Fluid

Abstract

This paper Due to the growing demand of energy and lesser availability of fossil fuels, it shifts our
concern towards Renewable energy sources. From all of the sources available to us solar energy is the best option
with minimum environmental impact. But the problem lies in efficiently collecting and converting this energy into
something useful form. The present study has been carried out to increase the efficiency of the solar collector by using
new type of solar collector (DASC-Direct absorption Solar collector) and different class of fluids called (Thermic
fluids). In conventional type of flat plate solar collectors we get more resistances whereas in DASC these resistances
are reduced . In the present work we have evaluated the collector efficiency using water and Thermic fluid with
different volume concentration.
At different mass flow rate of the thermic fluid and water the efficiency of the direct absorption solar flat
plate collector is to investigate and compare the efficiency of the flat plate collector by using thermic fluid and by
using water. And the efficiency of the system by using the thermic fluid is to be compared with the literature.
