CHARACTERISTICS OF SINGLE/DOUBLE-EFFECT COMBINATION ABSORPTION REFRIGERATOR DRIVEN BY WASTE HEAT OF PHOSPHORIC ACID FUEL CELL

Shisei Waragai, Tsuneo Uekusa

Abstract

This report analyzes the characteristics of an absorption refrigerator driven by steam and hot water and connected with a waste heat recovery system of a phosphoric-acid fuel-cell power-generation plant. First, a simulation of a waste heat recovery system is constructed and the characteristics of this system are confirmed. Next, throughout the experimental research and the simulation analysis, the influences of the cooling water temperature on the heat recovery and cooling capacity of the absorption refrigerator are clarified. And the effectiveness of a year-round cooling system using the absorption refrigerator driven by waste heat from the fuel cell is made clear.
