- Abstract
The present work is investigated Describes a non-conventional solar water heater that uses a thermosiphon-riser collector and the domain latent heat for the intermediate working fluid (ethanol). Testing was done for the experimental investigation from 8 a.m. to 4 p.m. utilizing a test rig that was placed in Baghdad City and tilted 45 degrees to the south. The test apparatus is made out of a solar absorber matte paint. with dimensions of (80*120) cm and 0.5 mm thickness. 4 mm for a double acrylic cover. Filling ratios of 50% and 100% are used to evaluate the ethanol at flow rates of 1 and 1.5 L/min. on September 6, 8, 11, 13, and October 4, 5, 14, 16, 2022, in sunny days. These experiments were carried out in order to determine the ideal filling ratios, flow rates, and mechanisms for enhancing thermal performance. This process is accomplished by contrasting the thermosiphon-riser collector with and without the attached helical spring around the core bar. in closed loop system. The experimental results showed that the highest daily efficiency is (70%), according to the data, was achieved at 1.5 L/min flow rate with 50% filling ratio in case of helical spring around the core bar within the thermosiphon riser collector.
