| Abstract: | The thermodynamic relations of the paramagentism are derived on the basics of its statistical properties.Using the paramegentic salt restricted to the Curie law as the working substance,a general model of magnetic Brayton refrigeration cycle is established.The adiabatic irreversibility and the thermal resistances are taken into account and their influences on the performance of the cycle are characterized.According to this cycle model,various optimal relations are deduced and the performance characteristics of the cycle are discussed deeply.The results obtained here will be helpful for the optimal design and the application of real magnetic Brayton refrigerator. |
