| description | <p dir="ltr">Solar thermal energy-driven double effect absorption refrigeration system (DE-ARS) for district cooling in smart cities is an efficient, and sustainable alternative for centralized air conditioning and concurrently harnesses low-grade solar energy. This work investigates ionic liquid based H<sub>2</sub>O-[mmim][DMP] mixture as an alternative working fluid to overcome the drawback of H<sub>2</sub>O–LiBr driven DE-ARS. The thermodynamic properties of H<sub>2</sub>O-[mmim][DMP] mixture is evaluated using the excess Gibbs free energy model. Performance modeling and simulation of DE-ARS is based on both energy and exergy analysis by applying the first and second laws of thermodynamic. The performance, and solution circulation ratio of parallel flow DE-ARS is assessed and optimized under various temperatures and solution distribution ratios. In comparison to the conventional H<sub>2</sub>O–LiBr, the proposed H<sub>2</sub>O-[mmim][DMP] working fluid achieves 5.22% and 4.95% improvement in COP and ECOP, respectively at T<sub>h</sub>/T<sub>e</sub>/T<sub>a</sub>/T<sub>c</sub> of 140/5/30/30°C . An optimization of generator temperature to achieve maximum COP and ECOP is performed for a wide range of evaporation temperature from 5 to 20°C and T<sub>a</sub>/T<sub>c</sub> from 30 to 40°C. An optimization of H<sub>2</sub>O-[mmim][DMP] mixture driven DE-ARS reveals the uppermost COP<sub>max</sub> and ECOP<sub>max</sub> of 1.81 and 0.69 for T<sub>e</sub> of 20°C and T<sub>a</sub>T<sub>c</sub>=30°C.</p><h2>Other Information</h2><p dir="ltr">Published in: Case Studies in Thermal Engineering<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.csite.2021.101382" target="_blank">https://dx.doi.org/10.1016/j.csite.2021.101382</a></p> |
