Abstract: A modular, frame-mounted power unit for converting heat from a low-grade energy source to electric power. Heat from a source is supplied to the power unit in the form of hot fluid circulated through a heat exchanger associated with a boiler. Liquid refrigerant in the boiler is vaporized and passes through the stages of an organic Rankine cycle, the expansion stage being carried out in a rotary, positive displacement expander. The condensing stage is carried out in a condenser associated with a cold heat exchanger which is connected to a supply of cooling fluid through cooling lines. The output shaft of the expander is connected to drive an electric power generator and individual fluid feed pumps for returning liquid refrigerant from the condenser to the boiler and for circulating hot and cold fluids through the hot and cold heat exchangers, respectively.
