Comment on ``first and second law analysis of ammonia/salt absorption refrigeration systems by L. Garousi Farshi et al. [Int. J. refrigeration 40 (2014) 111-121]”.
Abstract The attempt of this work is to comment on the wrongly formulated mathematical expressions by L. Garousi Farshi et al. in their published work which are used for predicting thermodynamic properties of working fluids (Ammonia/LiNO3 and Ammonia/NaSCN). L. Garousi Farshi et al. is also wrongly reported validation part in their published work due to wrong formulation of mathematical expressions of the thermodynamic properties. In addition to that four mathematical expressions are giving results as real number while remaining one is giving as imaginary number. In those above sections of the published work of L. Garousi Farshi et al., substantial changes are required.
