Application of magnetic field in the absorption systems: A review
Source abstract
Abstract
Although absorption technology is environment-friendly and energy-saving, the coefficient of performance (COP) of absorption systems is comparatively low. The absorber, a crucial component of these systems, is one of the important factors that influence the absorption system COP, and its efficiency significantly influences the system’s overall performance. Therefore, absorber performance needs to be improved to increase the COP. Generally, these four approaches are adopted to increase the absorber performance: enhancing heat and mass transfer by upgrading the structure, shape, and surface of the heat exchanger tubes, adding additives in the working solution, increasing absorption interface area by employing an atomizer and ultrasound inside the absorber, and applying a magnetic field around the absorber. This paper reviews the absorption enhancement by a magnetic field. The configurations of absorption experimental setups employing a magnetic field, the methods to build a magnetic field in absorption systems, and the influence of magnetic field intensity and its direction on absorption performance are all thoroughly reviewed. Insights about working solutions and nanoparticles employed in magnetized absorption systems are presented. Furthermore, the numerical modeling of absorption enhancement by an external magnetic field and the prospective research direction are also discussed. It is expected that this work will help in a more profound understanding of absorption enhancement by the magnetic field and provide a base for further improvements.
