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.

fig11: The effect of Tabs on the concentration of the strong and weak solution.

Mentions: In Figure 11 both Xs and Xw are plotted against the absorber temperature. It is obvious that when generating, condensing, and absorber/evaporator temperatures are kept constant, Xs does not vary with Tabs, but the Xw is increasing. The higher the evaporator or generator temperature is, the bigger the strong solution is. Consequently the higher Xs results in the higher flow ratio and can also increase the amount of the demanded heat input into the cycle [1].
