Abstract
Thermal properties of GEM PEHD polymer (high-density polyethylene geomembrane) as an absorber material in a prototype of solar sensor have been investigated in a temperature range from 300 K to 400 K. Results showed a dependency between temperature and its properties. Thus, increasing the power absorbed by the GEM PEHD increases its temperature and the useful power received by the air and then the air temperature. Overall losses increase with the increase of the temperature difference between the GEM PEHD and windows and this increases the efficiency of the solar collector and minimize the entropy of the system. Then the study of thermal aging is dedicated to the interpretation of various analyses on GEM PEHD before and after its use in the solar collector. The thermal aging GEM PEHD in the air is a physical loss and chemical consumption immediately followed by a brutal oxidation of the polymer. The losses would be governed primarily by the chemical consumption of antioxidants.
