A CASCADING MODEL OF AN ACTIVE MAGNETIC REGENERATOR SYSTEM

摘要

In recent years, significant amounts of studies have been done on modeling and analysis of active magneticrnregenerators (AMRs). Depending on the AMR geometry and the magnetocaloric material being modeled, thernAMR may not be able to provide the required performance demanded by practical applications. Some AMRrnmodels in the literature predict high performance but with relatively low temperature spans at either end ofrnthe AMR. Therefore, they may not be sufficient for practical applications, such as providing the heatrnexchanger temperature spans required for residential and commercial space air conditioning. To remedy this,rnone solution is cascading of multiple single layer AMRs. In this work, a cascading AMR model is presentedrnand studied. In a cascade configuration, N number of single layer AMRs are connected. The results show thatrnhigher hot and cold side temperature differences may be achieved compared to the ones obtained with arnsingle AMR rendering the solution more suitable for use in residential and commercial space conditioning.
