Performance Comparison of Triple-Effect Parallel Flow and Series Flow Absorption Refrigeration Systems

Hajizadeh Aghdam, F. Ranjbar and S.M. Seyed Mahmoudi

Abstract:
Energy and exergy analysis of triple effect series and parallel flow absorption refrigeration systems with lithium bromide/water as working fluid pair is presented in this study. Thermodynamic properties, mass and heat flow rate and exergy destruction are evaluated in each component of the system. Furthermore, The Coefficient of Performance (COP) and exergetic efficiency (E) of the absorption systems under different operating conditions are estimated. The results show that the exergy destruction at the generator and absorber are more than that of the other components which was expected due to mixing in these components. The results also show that the COP of the system increase slightly with an increase of High Temperature Generator (HTG) and evaporator temperature. However, the exergetic efficiency of the system decreases as the HTG and evaporator temperature increase. The latter results apply for both the series and parallel flow systems. Another indication of the results is a relative preference of parallel-flow in comparison with series-flow. In addition it can be seen that the triple effect system has higher COP in comparison with double and single effect types.
