摘要

磁制冷是利用磁性材料的磁热效应,使磁性材料的温度随磁场强度的变化而变化。它使用磁性材料代替蒸汽压缩制冷中使用的CFC、HCFC、HFC制冷剂,被认为是一种环保制冷技术。它也被认为是一种节能制冷技术,因为它不使用噪音大、耗电大的压缩机。本文利用磁致冷装置的实验结果,对磁致冷系统进行了热力学分析。磁制冷装置采用两组由永磁体组成的同心哈尔巴赫圆柱体。具体地说,计算了磁致冷系统的性能系数(COP),该系数是通过AMR床上工作流体的能量和驱动电动机的功输入来计算的。

Thermodynamic analysis on a magnetic refrigeration system
Abstract Magnetic refrigeration utilizes the magnetocaloric effect of a magnetic material, whose temperature changes according to the change of magnetic field strength. It is regarded as an eco-friendly refrigeration technology in that it uses magnetic materials as refrigerants instead of CFC, HCFC, and HFC refrigerants used in vapor compression refrigeration. It is also regarded as an energy-efficient refrigeration technology in that it does not use noisy and power-consuming compressors. This paper presents thermodynamic analysis on a magnetic refrigeration system using experimental results obtained from a magnetic refrigeration apparatus. The magnetic refrigeration apparatus was built using two sets of concentric Halbach cylinders consisting of permanent magnet segments. Specifically the coefficient of performance (COP) of the magnetic refrigeration system was calculated using the energy removed from the working fluid across an AMR bed and the work input to run electric motors.
