Abstract

A solar hot water generation system that makes use of a linear
Fresnel reflector solar concentrator (LFRSC) technique to concentrate
solar radiation onto a stationary absorber cavity suspended above the
concentrator plane is proposed. Heat loss from the trapezoidal cavity
absorber occurs via a complex interaction between radiation, convection
and conduction within the cavity, and then from cavity to the surroundings. This article describes and compares experimental and analytical
methods used to investigate the heat losses from the cavity absorbers
with and without plate underneath the absorber tubes. Reasonable
agreement is achieved between the two methods for heat loss in the
cavity absorber. Also, analytical and experimental thermal performance
analysis of LFRSC system is determined. The results are presented and
discussed.
