ABSTRACT:
An improved combined cycle low temperature engine system is provided in which a circulating expanding turbine medium is used to recover heat as it transverses it turbine path. The recovery of heat is accomplished by providing a series of heat exchangers and presenting the expanding turbine medium so that it is in heat exchange communication with the circulating refrigerant in the absorption refrigeration cycle. Previously recovery of heat from an absorption refrigeration subsystem was limited to cold condensate returning from the condenser of an ORC turbine on route to its boiler. By utilizing the turbine medium a more efficient system is provided. Specifically, a minimum of a double digit efficiency improvement when compared to the net power output of a conventional low-pressure steam turbine, is obtainable.
