Thermodynamic evaluation of LiCl-H2O and LiBr-H2O absorption refrigeration systems based on novel model and algorithm

In this work, a novel calculation method of absorption refrigeration system has developed which is not usual used in the most literatures. The model bases on energy and mass balances and Dühring equation to describe the primary absorption cycle and it is reliable and validated in the study of the LiCl-H₂O and LiBr-H₂O ARS simulations. The new computational procedure considering heat transfer process of components has been created for comparative analysis of the whole LiCl-H₂O and LiBr-H₂O absorption chillers with design size of heat exchanger. The computation work in absorption cycle will be greatly reduced by combining new method with computational procedure because it avoids complex iterative calculations of solution properties. In addition, the developed model can be extended for more absorption cycles using other working pairs to predict their performances with high precious and efficiency.
