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.

fig10: The effect of Tcon on the COP of the cycle for three different Teva.

Mentions: Figure 10 shows the effect of condenser's temperature on the COP of the system. This is by reason of the fact that the minimum system pressure raises with increasing the condenser temperature. By boosting the Tcon the strong solution concentration will go down which increases the flow ratio of the system. The bigger flow ratio will result in the lower absorber heat capacity and lower COP [19]. Figure 10 proposes that the condensation temperature should always be kept at its lowest setting [28] and the system has its best performance during the winter.
