G0610203 Performance Evaluation of Rotational Magneto caloric Heat Pump with Different Internal Layout of Magnetocaloric Materials

Abstract

An experimental study has been conducted to obtain thermal characteristics of the rotational type magnetic heat pump with two different layouts of magnetocaloric materials. These layouts are arranged with two different materials. Gd and Gd_<0.89>Dy_<0.11> which show large temperature change comparatively through low temperature range around 15 degree Celsius is applied and arranged in the center and the left side of the cell inside the rotor. The left side arranged layout showed maximum COP of 1.7 and showed larger than center arranged layout in most of the conditions. Center arranged layout showed maximum temperature difference of 3.4 degree Celsius, but its COP was smaller than left side arranged layout in most of the temperature range and flow rate range.
