Summary
Performance simulation has been carried out for several LiBr/H2O triple-effect cycles using the Absorption Simulation Model (ABSIM) . The systems investigated include the three-condenser-three-desorber (3C3D) cycle, forming an extension of the conventional double-effect cycle; and two cycles which additionally recover heat from the hot condensate leaving the highest temperature condenser by adding the heat to the lowest temperature desorber. These latter two cycles are called Double Condenser Coupled (DCC) cycles since each uses heat recovered from the highest temperature refrigerant to heat both the middle temperature desorber (heat of condensation) and the lowest temperature desorber (by further subcooling the condensed refrigerant), hence the ``double-coupling``. ABSIM, a modular computer code for simulation of absorption systems, was used to investigate the performances of each of the cycles and compare them on an equivalent basis. The performance simulation was carried out over a range of operating conditions, including some investigation into the influence of varying particular design parameters. Cooling coefficients of performance ranging from 1.27 for the series-flow 3C3D to 1.73 for the parallel-flow DCC have been calculated at the design point. Relative merits of these LiBr/H2O triple-effect cycle configurations are discussed.
