THE DEVELOPMEMT OF A NEW EVACUATED TUBE SOLAR COLLECTOR AND SYSTEM WITH NATURAL CIRCULATION

Abstract

In this study, a new type of evacuated tube solar collector, which can improve the reliability of the existing solar thermal system and annual energy efficiency, was developed. A solar thermal system that uses this collector was also developed and tested experimentally. The newly developed collector can fix the angle of the absorber plate inside the tube at a desired angle regardless of the installation angle of the collector module. In order to develop a system with natural circulation, a parametric study was carried out on the various parameters required for system optimization. The system finally proved the efficiency of the system through empirical tests.
