N2 - Based on the experimental characteristics of iso-field entropy varying with temperature for the room-temperature magnetic refrigeration material La(Fe0.88Si0.12)13H1 or Gd, the regenerative Ericsson refrigeration cycle using La(Fe0.88Si0.12)13H1 or Gd as the working substance is established and their thermodynamic performances are evaluated and analyzed. By means of numerical calculation, the influence of non-perfect regeneration on the main thermodynamic performances of the cycle is revealed and discussed. Furthermore, the coefficient of performance (COP), non-perfect regenerative heat quantity, and net cooling quantity of the Ericsson refrigeration cycle using La(Fe0.88Si0.12)13H1 or Gd as the working substance are compared. The results obtained show that it is beneficial to the cooling quantity of the cycles using La(Fe0.88Si0.12)13H1 or Gd as the working substance to operate in the region of Tcold >T0 and, at the condition of a same temperature span, the cooling quantity for La(Fe0.88Si0.12)13H1 is larger than that for Gd.
