THERMODYNAMIC DESIGN-DATA AND OPTIMUM DESIGN MAPS FOR ABSORPTION-REFRIGERATION SYSTEMS

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.
