A magnetic heat pump with porous magneto caloric material

Scientific paper ArODES

Summary:

At present magnetic refrigeration shows a realistic potential to penetrate into some niche markets in the field of cold and hot “production”. It is well known that a refrigerator for cooling and a heat pump for heating are machines based on the same principle. A small review on magnetic heat pump studies is outlined and a simple engineering calculation scheme to determine the coefficient of performance for a magnetic heat pump with a rotary porous structure heat exchanger is presented. Magnetic heat flux line distributions are calculated by a 2‐d finite element method numerical simulation program with the objective to obtain high field's μ0H with not too heavy permanent magnets assemblies. The porous structures are geometrically optimised to obtain maximal magnetic field inductions. It is shown that for a water/ethylene‐glycol magnetic heat pump the coefficient of performance is higher than that of a conventional heat pump. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Static and rotating active magnetic regenerators with porous heat exchangers for magnetic cooling

Scientific paper ArODES

Andreja Sarlah, Andrej Kitanovksi, Alojz Poredos, Peter W. Egolf, Osmann Sari, Fabrice Gendre, Christophe Besson

International Journal of Refrigeration, 2006, vol. 29, pp. 1332-1339

Link to the publication

Summary:

The operation behaviour of an active magnetic regenerator (AMR) with a wavy-structure, or a honeycomb-like regenerator bed was numerically investigated. The thermodynamic model was applied to a static regenerator and – in a generalized version – to a rotary type. The models take two-dimensional unsteady heat conduction in the magnetic material during the four basic processes of the AMR cycle into account. The numerical results were used to determine optimal arrangements of different magnetic materials in order to obtain larger temperature spans between both ends of the porous beds. Furthermore, a first study of magnetic flux lines in a porous rotary heat exchanger was performed.

Etude de faisabilité des pompes à chaleur magnétiques : Applications en Suisse

Peter W. Egolf, Gendre Fabrice, Andrej Kitanovski, Osmann Sari

2006, Bern : Bundesamt für Energie BFE, 69 p.

Link to the publication

Summary:

Cette étude de faisabilité montre qu’en l'état actuel des connaissances concernant les matériaux magnétocaloriques, l’usage des pompes à chaleur magnétiques, lors de la réfection des bâtiments dont le chauffage est par radiateur ou pour la production d’eau chaude sanitaire n’est pas pour l’instant réalisable.
Par contre un potentiel favorable existe dans le cas des bâtiments neufs, ayant un chauffage au sol. Dans ce dernier cas le « coefficient de performance (COP) » est plus élevé que celui d’une pompe à chaleur conventionnelle.
Le coût d’une pompe à chaleur magnétique à l’eau/éthylène-glycol sera trente pour-cent plus élevé que celui d’une pompe à chaleur à compression analogue.

Magnetic heat pumps :

an approximate energy efficiency and cost study 1.2

Peter W. Egolf, Fabrice Gendre, Andrej Kitanovski

Proceedings of the 2nd International Conference on Magnetic Refrigeration at Room Temperature

Link to the conference

Summary:

An extensive feasibility study on magnetic heat pumps, based on simple engineering calculus, reveals a good potential to build energy-efficient and cost-effective devices. The energy efficiency of a magnetic heat pump is better and the costs are slightly higher than for a conventional gas compression/expansion heat pump. This cost evaluation is based on a magneto caloric material prize, which probably will not be the minimal one being achieved in the near future. This example of a feasibility study may be applied exactly in the same manner to evaluate the potential (energy efficiency and costs) of similar applications; which are e.g. magnetic refrigerators or magnetic power conversion devices designed to operate in other market areas.

Phase change slurry system design with Dymola Modelica

Conference ArODES

Frédéric Brun, Fabrice Gendre, Ecaterina Siegenthaler, Osmann Sari, Peter W. Egolf

Proceedings of the 7th Conference on Phase-Change Materials and Slurries

Link to the conference

Summary:

For the modern object-oriented software Dymola Modelica a new library with thermodynamic modules of components of ice slurry systems has been created. The theoretical models for the modules of heat exchangers, storage tanks, pumps and tubes were chosen from former work performed by the Working Party on Ice Slurries of the International Institute of Refrigeration. The first test system is a new super market in Switzerland (Migros Uzwil) with 34 display cabinets, at present operated with commercially available brine. Numerical simulations of the system with a two-component, mono-phase (water glycol mixture) and a two-component, two-phase fluid, namely an ice slurry (water ethylene mixture), were performed and the results of four different operation cases are compared. An aim was to work out, on one hand, an accurate comparison of the energy demands and the related costs and, on the other hand, of the installation investment costs of the two systems with different fluids. Finally the intention is to make these two economical key parameters of concurrence systems available to decision makers, who are involved in the design of new similar plants.

A rotary heat exchanger magnetic refrigerator

Conference ArODES

Andrej Kitanovski, Peter W. Egolf, Fabrice Gendre, Osmann Sari, Christophe Besson

Proceedings of 1st IIF-IIR International Conference on Magnetic Refrigeration at Room Temperature

Link to the conference

Summary:

A magnetic refrigerator with a cylindrical heat exchanger of porous periodic structure has been designed and numerical system performance calculations have been performed. This refrigerating machine, respectively heat pump device, can be operated with air or water as working fluid. In the article the design of the new refrigerator is outlined and the coupled basic equations of magnetism and thermodynamics are presented, which contain three independant characteristic geometrical quantities characterizing the heat exchanger structure. Magnetic fields, magnetic flux densities, and coefficients of performances (COP), etc. were investigated for magnetic inductions B0 between 1 and 5 Tesla. The obtained COP’s are promising high compared to conventional refrigeration equipment working with gas compression and expansion.

Summary:

This article discusses the application of magnetic heat pump technology for heating buildings in Switzerland. Two systems are proposed, a floor heating system and a heating system for low-energy and office buildings with heat recovery devices. Their behaviour is numerically modelled and the results are compared with those of conventional heat pump systems.

A cellular method to calculate pressure drops of hydraulic circuits

Conference ArODES

Proceedings of the sixth Workshop on Ice Slurries of the IIR/Proceedings of the Second Conference on Phase Change Material and Slurry (PCM 2005)

Link to the conference

Summary:

A cellular method to calculate pressure drops of hydraulic circuits with laminar, turbulent and miscellaneous (not transitional) flow is presented. This cellular automaton-like method is based on a set of homogeneous rules and a successive iteration procedure. Its application is very simple, and it yields correct results also for a network of highest complexity. The good performance is demonstrated by presenting the results of numerical pressure drop calculations of a small parallel circuit with laminar flow. The theory also applies, only with small adaptations, to electrical circuits.
