摘要

We describe an analytic model for active caloric regenerator (ACR) cycles using any type of caloricrnmaterial. An ACR element is defined which provides expressions for cooling power and work input directlyrnwithout solving the governing partial differential equations for fluid and solid temperature. The ACRrnperformance is determined by fundamental material properties such as specific heat and adiabatic temperature changein addition to the properties that define an effective passive regenerator. ThernACR element includes losses due to conduction, convection, and depolarization. We demonstrate thernpredictive ability of the element model with comparisons of loss mechanisms in an ACR using a first orderrnmagnetocaloric material. We then show how the ACR element is used with regenerators made up of layersrnof different materials with a two-layer ACR example. In addition to providing a clear functional relationshiprnfor performance, the element model allows for fast screening of materials, design, and operating conditions.
