Abstract
A thermodynamic optimization analysis of single effect LiBr-H2O vapour absorption cooling system of 1 TR capacity is conducted based on first and second laws. Mathematical models derived from thermodynamics theory, are employed in engineering equation solver to perform the calculations. Minimum generator temperature required to operate the system that is cut off temperature has been evaluated. Realistic comparison of thermodynamic first and second law approaches have also been evaluated. It is found that cut off temperature of system decreases with evaporator temperature and increases with condenser and absorber temperature. It is observed that optimum generator temperature decreases with evaporator temperature and increases with condenser temperature. Hence it is feasible to find out optimum generator temperature for various condenser-evaporator temperatures. Corresponding contour plots have also been depicted for optimum generator temperature. Adoption of optimized exergy approach is advisable owing to fact that exergy destruction rate is more sensitive compared to COP of system.
