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.

fig15: The effect of economizer on COP of the cycle.

Mentions: In Figure 15 the COP is plotted against heat exchanger efficiencies (ε). It is obviously evident that ε has a major role on the COP of the system. The variation of the economizer effectiveness can increase the COP up to 21%. It can be concluded that the effectiveness of the economizers should be as high as possible, that is, a reasonable result according to the heat transfer phenomenon.
