BOTTOMING CYCLE A system for air conditioning and generating electrical power including a fuel-fired internal combustion engine, an electrical motor/generator, and a vapor compressor/expander all interconnected. The vapor compressor/expander driven by the engine operates in one mode with an evaporator and a condenser in a generally conventional refrigeration cycle. In an alternative mode, the vapor compressor/expander is operated in reverse by refrigerant boiled in the evaporator by the rejected heat of the engine and condensed in the condenser and contributes mechanical power to that of the engine to drive the motor/ generator. The motor/generator can be supplied external electrical energy to operate as a motor to drive the compressor/expander during periods of nonoperation of the engine.
