Characteristics of a Magnetic Refrigerator with New Magnetocaloric Materials

摘要

The aim of this study is to put a cooling technology using a magnetocaloric effect to practical use for air conditioners of railway vehicles in order to save energy. New magnetcaloric materials which have larger a magnetocaloric effect compared with Gd have been developed in the region of room temperature. Nevertheless, little discussion exists about how much the new materials affect the properties of a magnetocaloric cooling system. Therefore, the characteristics of the cooling system with Gd and La(Fe_(0.84)Co_(0.06)Si_(0.10))_(13) have been studied experimentally and analytically.
