Summary

In recent years, cogeneration systems with fuel cells have occupied the attention of the world from a standpoint of environmental protection and the effective energy use. Since the waste heat of phosphoric acid fuel cell is recovered in two forms of steam (0.6 megapascal) and hot water (65 to 90 deg C), this type of absorption refrigerator is driven by two heat sources. The authors experimented on this absorption refrigerator, the standard cooling capacity of which is 35 kilowatts. There was a mutual intervention when the supply condition of steam pressure was changed. Also the effects of hot water temperature, cooling water temperature and chilled water temperature for the performance of this absorption refrigerator were clarified. As a result, the effectiveness of using steam and hot water simultaneously in year-round operation is shown. It is clarified that the utilization of the low boiling temperature medium as the heat transfer medium for air-conditioner is effective.
