✦ Synopsis

The free choice of operating temperatures in absorption systems is limited by the Gibbs phase rule and the thermodynamic properties of the 'working pair. Tables of possible combinations of operating temperatures and concentrations, including flow ratios, Carnot coefficients of performance and enthalpybased coefficients of performance have been presented for ammonia-lithium nitrate absorption systems for simultaneous cooling and heating. The interactions of operating temperatures have been illustrated graphically.
