Thermodynamic design data and optimum design maps for absorption refrigeration systems

Absorption refrigeration systems increasingly attract research interests. The most common cycles are LiBr/H2O and H2O/NH3 absorption machines which have served as standards for comparison in studying and developing new cycles and new absorbent/refrigerant pairs. In the present study, up-to-date thermodynamic properties for LiBr/H2O and H2O/NH3 solution are compiled and are used in cycle simulation. Detailed thermodynamic design data and optimum design maps are presented. These results form a source of reference for developing new cycles and searching for new absorbent/refrigerant pairs. They can also be used in selecting operating conditions for existing systems and achieving automatic control for maintaining optimum operation of the systems. Copyright (C) 1996 Elsevier Science Ltd.
