This paper presents an investigation of the working cycle of a metal hydride heat transformer for upgrading waste heat. A mathematical model for calculation of the heat and mass transfer processes in the metal hydride heat transformer is suggested. The method for balancing the heat and mass exchanges in the thermodynamic cycle is developed. This method essentially takes into account the pressure drop inside a reacting hydride bed.
