Abstract:
A two-dimensional transient model of a new magnetic refrigeration system using thermoelectric refrigera-tion elements was established using COMSOL Multiphysics.The effects of input current,utilization factor,and number of refrigeration units on the performance of the new system were studied.The results showed that:both the cooling power and the temperature span increase proportionally with the increase of the input current.For different input currents,the op-timum C
OP corresponds to different utilization factor.The optimal utilization factor of refrigeration power and C
OP is found,and the optimal utilization factor of refrigeration power increases with the increase of input current.The cooling power and C
OP increases as the number of refrigeration units increases.The simulation results provide valuable reference for the mechanism and experimental study of the new magnetic refrigeration system.
