In our recent research, the sorbent used is a salt-mixture that has been developed by DY Refrigeration Inc. and has been used in the ice-maker fishery industry [1]. The major active component of the sorbent is sodium thiocyanate (NH3–NaSCN). Ammonia (NH3) is used as sorptive [2]. The advantages provided by this system over other absorption units include lower generator and evaporator temperatures, a higher coefficient of performance (COP). Compared with NH3–H2O system, the NH3–NaSCN adsorption system doesn't need the rectifier because there are only NH3 in the vapor phase and the salt (NaSCN) doesn't evaporate at all, that makes the system simpler and cheaper. Among the first studies on an NH3–NaSCN system are those of Blytas and Daniels [3] and Sargent and Beckman [4]. Tyagi [5] and Aggarawal et al. [6] provided a review on ammonia-salts absorption refrigeration systems. Thermodynamic and physical properties for the NH3–LiNO3, and NH3–NaSCN solutions have been presented by Ferreira [7], while interesting energy performance comparisons between NH3–H2O, NH3–LiNO3 and NH3–NaSCN absorption systems may be found in the works of Sun [8].
