Abstract
The solar cooling technology is a promising alternative to the conventional electrical driven air conditioners, and one of the optimum systems is solar double-effect absorption system. The main objective of this research is to predict, analyze and optimize the performance of the double-effect absorption system. Also it is required to predict the coefficient of performance (COP) and exergetic efficiency (ηex) of the system, and to formulate them in equations as functions of the operating parameters of the cycle. A computer program has been developed by EES (Engineering Equation Solver) software to describe the mathematical model of the used absorption system to carry out the energy and exergy analyses, which were used to analyze the thermodynamic performance of the system. By studying the energetic and exergetic performance of the double-effect absorption cycle for evaporator temperature range of 2–10 °C, absorber and condenser temperature range of 28–45 °C, and HPG temperature range of 100–200 °C, two equations, which are functions of the operating temperatures, have been developed to predict the performance of the cycle.
