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.

fig9: The effect of Tabs on the COP of the cycle for three different Teva.

Mentions: Figure 9 depicts the variation of COP with Tabs in three different evaporator temperatures. It is clear that it has a similar trend with that of Figure 8 which shows the decreasing behavior of COP by increasing GTL. Also by increasing Tabs, the concentration of the weak solution and consequently the flow ratio increase which leads into a decrease in the absorber heat capacity [8, 10, 20, 39].
