  • A magnetic heat pump with porous magneto caloric material
    Vuarnoz, Didier ...
    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 machinesbased 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 0H 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.
