This paper deals with the cooling performance of a room-temperature magnetic refrigerator using an active magnetic regenerator (AMR). The AMR system basically has four sequential processes: magnetization, heat exchange fluid flow, demagnetization and fluid flow. The fundamental heat transport characteristics of each processes of the AMR cycle are investigated in detail, and both the cooling power and the total system performance are evaluated when the system is running continuously. In addition, we devise the appropriate simulation model of the heat transfer process inside the AMR particle bed. The temperature profile inside the AMR bed and the cooling characteristics of the room temperature magnetic regenerator using AMR are performed analytically. In this research, the validity of the analytical model is verified by comparing the experimental results with the analytical results.
