Abstract: The free choice of operating temperatures in absorption systems is limited by the Gibbs phase rule and thermodynamic properties of the working pair. For a given combination of temperatures, the concentrations in the absorber and the generator for a given working pair are fixed automatically. This determines the flow ratio. Therefore, for any particular working pair, the coefficient of performance is related to the flow ratio. Tables of possible combinations of operating temperatures and concentrations, including flow ratios, Carnot coefficients of performance and enthalpy-based coefficients of performance, have been presented for water---lithium bromide absorption systems for cooling. The interactions of operating temperatures have been illustrated graphically.
