Other Refrigeration Systems

The chapter presents alternative refrigeration systems that function based on principles distinct from traditional methods like vapor compression and absorption cycles. It discusses four main systems: steam-jet refrigeration, vortex tube refrigeration, thermoelectric refrigeration, and magnetic refrigeration, each characterized by unique operating principles, advantages, and limitations. A summary table encapsulates the key features and applications of these systems.
