Effect of Operating Temperature on the Performance and Thermal Load of Water/Lithium Bromide Vapour Absorption Heat Pump in the Absence of Solution Heat Exchanger

Abstract:

In this investigation, a thorough thermodynamic analysis of the water/lithium bromide absorption refrigeration cycle in the absence of solution heat exchanger is performed. The influence of operating temperature on the thermal loads of components, COP_c (Carnot Coefficient of Performance), COP_E (Enthalpy based Coefficient of Performance) and efficiency ratio (η) is studied. It is concluded that the COP_c and COP_E values decreases with increasing condenser and absorber temperature but increase with increasing generator and evaporator temperatures .
