Abstract

The goal of this study was to see how a compound parabolic concentrating (CPC) reflector may improve the heat quality of a heat pipe evacuated-tube collectors. The reflectors composed of two distinct materials were used in the study: galvanized and stainless steel sheet. Eight vacuum glass tubes with inner and outer diameters of 33.80 mm and 47.20 mm, and a length of 1,836 mm were utilized with a CPC reflector height of 86.20 mm. The results of a research comparing the heat quality provided by solar water heating system (SWHS) with and without CPC reflectors revealed that installing CPC reflectors can increase the heat quality produced by the SWHS. When CPC reflectors made of galvanized sheet are used, the system’s thermal efficiency is at its highest. In addition, when it comes to the highest hot water temperature that the system can provide, though. The method utilizing CPC reflectors constructed of stainless steel sheets was discovered to be the most appropriate.
