Thermodynamic design data and performance evaluation of the water plus lithium bromide plus lithium iodide plus lithium nitrate plus lithium chloride system for absorption chiller

Abstract

Duhring (P-T-X) and enthalpy-concentration (H-X-T) diagrams of the H2O + LiBr + LINO3 + LiI + LiCl (mole ratio of LiBr : LiNO3 : LiI :LiCl = 5: 1 : 1 :2) system were constructed by using the experimental data sets. Thermodynamic design data for a double-effect series-flow absorption chiller were calculated at various operating conditions [2 less than or equal to T(e)less than or equal to 14 degrees C, 30 less than or equal to T(a)less than or equal to 50 degrees C, 30 less than or equal to T(c)less than or equal to 50 degrees C, T-gh(COP = 0) less than or equal to T-gh less than or equal to T-gh (crystallization limit)] by a computer simulation. The proposed working fluid was found to be applicable to cycle operation of air-cooled absorption chiller with no crystallization problem at higher absorber temperature.
