Abstract: A thermo-magnetism cycle apparatus has a first magneto-caloric element (MCE) element on a low temperature side and a second MCE element on a high temperature side. A first heat transfer medium flows in the first MCE element and a second heat transfer medium flows in the second MCE element. A third MCE element has a first flow passage that flows the first heat transfer medium and a second flow passage that flows the second heat transfer medium. The third MCE element absorbs heat from the first heat transfer medium utilizing a magneto-caloric process and dissipates the absorbed heat partially to the second heat transfer medium. As such, the third MCE element actively transfers heat between the two heat transfer media via the magneto-caloric process. The third MCE element also passively transfers heat between the two heat transfer media.

Abstract: A refrigeration method reduces compressor energy usage in a hydrocarbon refrigeration system by incorporating a distillation/adsorption cycle. The method and related systems can use waste or other heat sources to replace a portion of the mechanical energy of the compression cycle in a novel process scheme easily adapted to either new or existing refrigeration systems. The present hybrid vapor compression-adsorption cycle combines both the refrigerant and adsorption medium in the compression cycle and separates these components using conventional multi-stage distillation to then separate them for the refrigeration and adsorption cycles.

Frost can be detected by a sensing mechanism and the refrigerant and air cycles can be reversed in response to detecting the frost. The frost can be removed quickly without removing the goods from the refrigerant.
