Thermal loss estimation for active magnetic regenerator aiming at railway air-conditioner application.

Number: pap. 112

Summary

We carried out a basic experiment and numerical analysis for estimating the losses quantitatively. A heat transfer fluid back and forth moving in an active magnetic regenerator (AMR) mixes with the fluid in the plumbing connected to the AMR at both ends of the AMR. Mixing of those fluids that have different temperatures causes a decreasing of the cooling capacity. It was found out that displacers placed at the both ends of the AMR could prevent those fluids from mixing. The result of the numerical analysis that considered the heat leak from the ambient temperature had a good agreement to the result of the experiment of the AMR with displacers placed at the both ends of the AMR.
