Study of Magnetocaloric Refrigerator on Room Temperature for Air Conditioners of Railway

Abstract

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(Fe_0.84Co_0.06Si_0.10)₁₃ has an operating temperature that is lower than Gd. Accordingly, a magnetocaloric refrigerator system which has a magnetocaloric material of La(Fe_0.84Co_0.06Si_0.10)₁₃ is reported in this paper.
