Abstract: The system for augmented electric power generation with distilled water output employs a combined cycle gas turbine power generation system for electrical power generation. A multistage evaporator uses steam drawn from the steam turbine as a heating medium to power the multistage evaporator for the production of distilled water.

Thus, the system's efficiency is increased because the preheating of the wastewater supply to the multistage evaporator improves efficiency of the distillation process, while cooling of the gas turbine intake air increases power generated by the gas turbine, increasing both power and steam output from the combined cycle gas turbine power generation system.

Abstract: Controlling displacement in a variable displacement compressor of an automobile air conditioning system entails detecting the temperature and humidity level of air entering the evaporator, setting a target air probe temperature from inside the automobile, and reading the evaporator air-out temperature at the temperature probe.
