13. Air-Condition and Refrigeration

A magnetocaloric heat pump has a higher theoretical coefficient of performance than a conventional vapor compression heat pump. In recent years, many studies have been conducted to improve the refrigeration capacity of the magnetocaloric heat pump(T. Kawanami et al.,2017). The refrigeration capacity of magnetic heat pump systems depend on the magnetic field intensity imparted to the magnetocaloric material (MCM) as the refrigerant of system. In this study, the effect of applied magnetic field intensity on the refrigeration capacity and the maximum temperature difference generated were clarified using a numerical simulation. As a result, it was found that the applied magnetic field intensity of 1.5T were about three times greater than those of 0.5T, both in terms of maximum refrigeration capacity and maximum temperature difference generated.
