Abstract
One of the largest problems of a cogeneration system is the application to changing ratio of thermal and power demand. Stirling cycle is useful for a cogeneration system because it can convert a thermal energy to power and vise versa. The Stirling cycle is applied to a cogeneration system as a bottoming cycle. The performance of the proposed system is estimated with the characteristics of the topping cycle and heat transfer of heat exchangers. When a gasoline engine is chosen as a topping cycle, the maximum efficiency of power output and thermal output is 24.5% and 143%, respectively. Furthermore, the proposed system is useful because it can be applied to any kinds of topping cycles.
