IIR document

Scale up of MnFePSi materials in a broad temperature range and manufacturing of advanced heat exchanger structures.

Number: pap. 74

Author(s) : DÖTZ F., ASTEN D. van, BARRERA-MEDRANO D., et al.

Summary

We have developed a straightforward synthesis route of MnFePSi spheres via gas atomization yielding material stocks ranging from Curie temperatures of 250 to 330K. These base materials can be incorporated into highly stable heat exchanger beds of packed spheres allowing the consequent optimization of system parameters as porosity, pressure drop, etc. in active regenerator tests.We will show initial results on advanced heat exchanger structures displaying lower pressure drop and thereby giving room for higher efficiency devices.
