Abstract

The exact theoretical refrigeration and transformer thermodynamic cycles, of units working with H2O/LiBr, are presented on the enthalpy-temperature as well as on the temperature-entropy diagram. The heat quantities involved with, have been calculated for many such cycles. Afterwards the obtained results have been correlated by short relations allowing the fast computation of the related quantities. The fast algorithm obtained can be used to predict optimal operating conditions in a very short computer time even if personal computers are used to.
