This study aims at practical use of a cooling technology using a magnetocaloric effect for the purpose of energy saving of air conditioners of railway. A method to cascade magnetocaloric materials having the different temperatures is suggested to obtain an operating temperature required by air conditioner because a work point of the magnetocaloric material is limited to temperature around the Curie point of the material. La(Fe0.84Co0.06Si0.10)13 has an operating temperature that is lower than Gd. Accordingly, a magnetocaloric refrigerator system which has a magnetocaloric material of La(Fe0.84Co0.06Si0.10)13 is reported in this paper.
