排熱利用吸収サイクルの特性シミュレーション Characteristics Simulation of the Waste-Heat Utilization Absorption Cycles
In the recent years double effect cycles have gathered a lot of attention because of their good efficiency particularly fitting with preoccupation of energy saving and with recent environmental problems. Simulation studies on double effect absorption cycles for refrigeration purposes have been performed for H<SUB>2</SUB>O/LiBr fair. The purpose of this study is the objective for evaluating the possibilities of effectively utilizing waste-heat as a secondary heat source for the low temperature generator. The efficiency of the different cycles have been studied and the simulation results show that higher coefficient of performance could be obtained for standard parallel cycle (TYPE PA). The optimum designs and operating conditions were determined based on the operating conditions and the coefficient of performance. The effectiveness of introducing a waste-heat source of about the same temperature level as the low temperature generator is demonstrated. If the cycles are assisted by fuel cell waste-heat, the input of waste-heat to low temperature generation parallel cycle (TYPE PB) yields highest COP.
