The generator pressure Pg is in equilibrium with the solution temperature in the generatorTy = To and its concentration Xg = X6. The generator pressure equals the condenser pressure Pc.The condenser temperature is To = Til, and its vapor pressure is Pc. Therefore, from the equilibrium equation of the LiBr-H2O solution, the generator temperature T, can be expressed as a function of its concentration Xy and the condenser temperature Ic as follows [1]:
