Exergy Analysis of a Parallel-Plate Active Magnetic Regenerator with Nanofluids

Abstract: This paper analyzes the energetic and exergy performance of an active magnetic regenerative refrigerator using water-based Al 2 O 3 nanofluids as heat transfer fluids. A 1D numerical model has been extensively used to quantify the exergy performance of a system composed of a parallel-plate regenerator, magnetic source, pump, heat exchangers and control valves. Al 2 O 3 -water based nanofluids are tested thanks to CoolProp library, accounting for temperature-dependent properties, and appropriate correlations. T… Show more

“…A pressure cell is used to change the operation pressure. In regards to solid-state refrigeration, just two methods have been studied for the application of nanofluids in the caloric systems, and both were focused on magnetocaloric refrigeration [65,66]. Working with nanofluids in other caloric-effects-based cooling systems is still an unexplored field.…”

“…Caloric refrigeration embraces all the cooling techniques and was founded on a physical phenomenon according to which, due to an adiabatic change in the intensity of an external field, a variation of temperature (∆T ad ) is detected in a solid-state material to which the field is applied [15,16]. The specificity of the field particularizes such effects classified as caloric; a magnetic field generates a magnetocaloric effect (MCE) [17][18][19], electric fields are associated with electrocaloric In regards to solid-state refrigeration, just two methods have been studied for the application of nanofluids in the caloric systems, and both were focused on magnetocaloric refrigeration [65,66].

“…The thermophysical properties of the alumina-water nanofluids are dependent on the volume fraction of nanofluids ; therefore, to include such dependence in our caloric heatpump model, we adopted the following correlations demonstrated in previous investigations [17,27]…”

“…Chiba in his work [16] tested the energy performance of an Active Magnetocaloric Regenerative refrigeration (AMR) cycle operating near room temperature using nanofluids as heattransfer fluid, in order to enhance the heat transfer in the regenerator bed during the fluid-flow phases. Mugica et al [17], analyzed the energetic and exergy performances of parallel-plate AMR refrigerator though a 1-D model. Both of the investigations [16,17] employed water-based Al2O3 nanofluids as HTF.…”
