Résumé

A magnetic heat pump has several advantages, such as not carrying any greenhouse gases and generating potential energy savings, over conventional vapor compression heat pumps. Several studies have been conducted to evaluate the performance of magnetic heat pumps operated in an active magnetic regeneration (AMR) cycle. Most of those studies evaluated the capability of AMR cycles using flow rate and average flow velocity as variables. In contrast, the refrigeration performance of the AMR magnetic heat pump is strongly influenced by the flow pattern during one cycle, besides these typical flow conditions. In this study, the effect of the flow pattern of the heat exchange medium during the AMR cycle on the temperature change behavior of the magnetic refrigeration system was investigated. As a result, it was found that the temperature span generated by the AMR depends on the pattern of flow velocity variations of the heat exchange medium.
