Breakthroughs in magnetic refrigeration
WebTo optimize the performance of the transcritical CO2 two-stage compression refrigeration system, the energy analysis and the exergy analysis are conducted. It is found that higher COP, lower compression power, and less exergy destruction can be achieved when the auxiliary gas cooler is applied. Moreover, the discharge temperature of the compound … WebApr 1, 2003 · 1. Introduction. Magnetic refrigeration is based on the magneto-caloric effect (MCE). This is an isothermal magnetic-entropy change or an adiabatic temperature change of a magnetic material upon application of a magnetic field. It is becoming a promising technology to replace the conventional gas-compression/expansion technique.
