Summary

In order to check the theoretical performance of the new working fluid LiBr + LiNO3 + H2O (mole ratio of LiBr and LiNO3 = 4:1), the theoretical coefficients of performance (COP) of this working fluid and LiBr + H2O were calculated at various operating conditions. The improvement of crystallization problem was also checked. This proposed working fluid was proved to increase the COP by about 5% than LiBr + H2O. The cooling water through absorber and evaporator was heated to higher temperature by this new working fluid. LiBr + LiNO3 + H2O was found to be an alternative to the conventional LiBr + H2O with higher COP and less corrosivity. [Reprinted with permission from Elsevier. Copyright, 2010].
