Magnetic cycles for heat pumping and power generation

点击翻译按钮获取中文摘要

The objective of the research program is the development of energy conversion devices using magnetic cycles. Magnetocaloric devices are reversible heat engines utilizing magnetic ordering to effect work and heat transfer. They can be used for refrigeration, heat pumping, and to generate power. The potential for increased efficiency comes from highly reversible work transfer coupled with inherent work recovery. The use of solid working materials and environmentally benign heat transfer fluids ensures that the production and release of GHG and ozone depleting substances are minimized. The ability to generate work provides a new approach to power generation from low-grade sources including solar, biomass, and waste-heat.
