| One of the important and effective criteria in performance of solar collectors is the adsorption geometry. In this study, a three-dimensional and fixed solar collector with pyramid geometry and diagonal risers which is designed and built by the author, has been experimentally investigated in southern Iran. Studies included the effects of environmental factors such as changes in radiation, angles and temperatures over time. The thermal performance of the collector has been evaluated according to the ASHRAE standard. Experimental results showed that in addition to the proper stability of this geometry, the rate of return in the normal state and using water as the operating fluid is approximately 35.1% on average and the maximum return obtained was about 46.2%. In addition, in the experiment by using of CuO-Water nanofluid with a concentration of 0.1% in the collector, it was found that the collector efficiency increases about 6% compared to the use of ordinary water. | ||
