Absorption refrigeration systems increasingly attract research interes
ts. The most common cycles are LiBr/H2O and H2O/NH3 absorption machine
s which have served as standards for comparison in studying and develo
ping new cycles and new absorbent/refrigerant pairs. In the present st
udy, up-to-date thermodynamic properties for LiBr/H2O and H2O/NH3 solu
tion are compiled and are used in cycle simulation. Detailed thermodyn
amic 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 o
perating conditions for existing systems and achieving automatic contr
ol for maintaining optimum operation of the systems. Copyright (C) 199
