Abstract: In this work, the mathematical model and simulation of the series and parallel flow double effect absorption type combined power and cooling cycle (DACPC) has been done in Scilab (open source software) using highly accurate thermodynamic correlations available in the literature. Sensitivity analysis of the operating parameters of a cycle has been studied and it has been optimised using Scilab's inbuilt function 'optim' to get maximum exergy efficiency for given evaporator and absorber temperature. The DACPC has been compared with other combined power and cooling cycle from the literature and found that its exergy efficiency is significantly more by 7-41%. The data of optimised operating conditions is generated and it will be useful for designing the cycle for practical applications. The maximum exergy efficiency of DACPC is in a range of 60% to 65%.
