Modelling the transient behaviour of an active magnetic regenerative refrigerator.

Author(s) : ENGELBRECHT K., NELLIS G., KLEIN S.

Summary

Active magnetic regenerative refrigeration (AMRR) systems represent an environmentally attractive space cooling alternative because they do not require a synthetic working fluid. Previous work has shown that AMRR systems have the potential to be as efficient as vapour compression systems provided the size of the regenerator is adequately large. However, the transient and part-load characteristics of AMRR systems have not been studied. A numerical AMRR model has been developed that solves the coupled fluid and solid energy balances. The predicted temperature profiles are used to calculate refrigeration capacity, heat rejection, and other cycle parameters. This model is used to predict the startup characteristics and part-load performance of a well-designed AMRR system.
