Summary

A micro-scale distributed power generation system, which means a micro-cogeneration system in most cases, has received great attention from the standpoint of saving fossil fuel consumption and preventing global warming. Especially, a polymer electrolyte fuel cell (PEFC) is considered the most promising power generation system for small-scale commercial and residential use. In the PEFC cogeneration system, a small amount of waste heat at low temperature from a cell stack is used to produce hot water. Tje authors propose a new heat utilization method of this waste heat for air conditioning. In this paper, theoretical investigations of a high-performance absorption refrigerating machine were carried out by computer simulation. The influences of the cooling water temperature, surfactant, and highly efficient heating surface on the refrigeration ability were clarified quantitatively.
