Application of Exergetic Efficiency and Yield for Determination of Performance of Absorption Heat Pump

Recovery and reuse of lost energy by absorption heat pumps which can produced useful heat and cold, are one of the main method to overcome energy needs. For optimum application of absorption heat pump, the conventional criteria which are based on principles of thermodynamic laws, should be changed and suitable criteria should be defined consequently. In this paper, at first, the absorption heat pump considers as exergetic dipole/quatrepole and then, performance criteria and correlations of the heat pump have been illustrated. A case study showed that, exergetic efficiency and yield as novel criteria, can illustrate absorption heat pump performance with good precision.
