ABSTRACT
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.

fig6: The effect of BP1 on the COP of the cycle for three different Teva.

Mentions: Figures 6 and 7 show the variation of the COP by the first and second Bypass ratios. It is clear that the COP is higher for smaller amounts of BP1 and higher quantities of BP2. This means that the temperature of the point 29 will become higher with considered amounts of bypass ratios which leads to increasing heat recovery in the third heat exchanger. This is in agreement with those reported in [27] whom stated the fact that the third heat exchanger has a much greater influence on the cycle's performance than any other heat exchanger.
