The two-stage metal hydride heat transformer
Metal hydrides can be utilized as working materials in different types of processes in the field of energy technology. Among others, thermally driven heat transformation devices are very promising solutions for the rational use of energy. Main applications for thermodynamic metal hydride machines are the heat transformer for generation of high temperatures, or the heat pump/refrigerator for generation of both high and low temperatures. Such metal hydride machines can be used in a variety of applications due to their large operating temperature range. This paper gives an overview of the experimental setup of a prototype heat transformer for industrial use, providing useful heat continuous output of about 7 kW at a temperature of about 190-200 degrees C with a driving heat of 130-135 degrees C and a cooling water temperature of 40 degrees C.
