IIR documentSummary
Metal hydride heat pumps are chemical heat pumps, which do not use conventional refrigerants such as CFCs. Instead, they use hydrogen as a working fluid. The paper presents the basic underlying theory and operating principles of a this heat pump, this includes characterization of the thermodynamic properties of metal hydrides and cycle representations on Van't Hoff and pressure-composition-temperature diagrams. The design and operating parameters affecting heat pump performance are also discussed. A performance index for an metal hydride heat pump, which allows comparison with other systems is presented. Current research works, research needs, and further developments are also discussed.
