Because energy consumption by demand for electricity, air-conditioning and hot water supply is so large in the small-scale stores such as a restaurant and a convenience store, it is very effective in saving energy and environmental preservation to introduce a power generation and heat supply system. Ill this paper, examination in optimization of operating the systems applied to these small-scale stores is conducted. The system consists of a Stirling engine generator, a combustor, an exhaust gas heat exchanger or air pre-heater, and a low temperature regenerative desiccant air-conditioner. From the results of examination in optimization, it makes clear that improvement of energy utilization efficiency and running cost down are almost realized, butfurther examination is required for reduction in CO_2 emissions.
