STUDY ON THERMAL PERFORMANCE OF PCM INTEGRATED CONCENTRATED SOLAR ABSORBER

Abstract

In this study,a cylindrical solar absorber is investigated with integrated phase change material (PCM). The objective of this work is to store the heat energy at the focal point using thermal masses. A eutectic mixture of NaNO3 and KNO3 in 60:40 ratio is used as the phase change material. The absorber is placed at the focus of Scheffler reflector of 16 m2 aperture area. The receiver is heated to different upper temperature limits and the heat energy stored is determined based on the temperature measurements.
