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, COPc (Carnot Coefficient of Performance), COPE (Enthalpy based Coefficient of Performance) and efficiency ratio (η) is studied. It is concluded that the COPc and COPE values decreases with increasing condenser and absorber temperature but increase with increasing generator and evaporator temperatures .
