First law of thermodynamics has been used to analyze and optimize inclusively the performance of a triple absorption heat transformer operating with LiBr/H2O as the working pair. A thermodynamic model was developed in EES (engineering equation solver) to estimate the performance of the system in terms of the most essential parameters. The assumed parameters are the temperature of the main components, weak and strong solutions, economizers' efficiencies, and bypass ratios. The whole cycle is optimized by EES software from the viewpoint of maximizing the COP via applying the direct search method. The optimization results showed that the COP of 0.2491 is reachable by the proposed cycle.

A combined cogeneration cycle is proposed in which the waste heat from an ejector-expansion trans-critical CO 2 refrigeration cycle is utilized for power production and water purification simultaneously. The waste heat utilization was performed by means of a CO 2 supercritical power cycle and a desalination system for pure water production. In order to run the desalination system, an absorption heat transformer is employed to upgrade the lower temperature waste heat. Thermodynamic models are developed for both the ejector-expansion trans-critical CO 2 cycle and the combined cogeneration cycle consisting of all the above mentioned cycles. A parametric study is conducted to investigate and optimize the performance of each cycle under various operating conditions. It is found that, at the optimum conditions, the energy efficiency ratio of combined cogeneration cycle is about 13-45% higher than the coefficient of performance of the ejector-expansion trans-critical CO 2 cycle. It is also concluded that, as the gas cooler temperature increases, the pure water production rate in the combined cogeneration cycle is increased.
