This paper discussed several kinds of power cycle configuration using ammonia-water mixtures to achieve heat, power and cooling cogeneration. The benefits of these configurations are simple and inexpensive compared with Kalina cycles, and can be used as the bottoming cycle under wide range of heat source such as waste heat from diesel engine, fuel cells, and small gas turbine with temperature ranging from 150∿450℃. Theoretical thermodynamic simulation is made for different configurations. The relationship of the process parameters such as pressure, temperature of heat source, component of mixtures and the cycle efficiency are analyzed through numerical simulation. In this study we used a software package that we developed for high temperature ammonia-water thermodynamic properties. On the basis of the above study, we can develop parameters optimization for the design of systems using mixtures under various heat source.
