Comparison of the performances of NH3-H2O, NH3-LiNO3 and NH3-NaSCN absorption refrigeration systems

In recent years, research has been devoted to improvement of the performance of ammonia-water absorption refrigeration systems. In this study, thermodynamic analyses for ammonia-water, ammonia-lithium nitrate and ammonia-sodium thiocyanate cycles are performed. Detailed thermodynamic properties of these binary fluids are expressed in polynomial equations. The performances of these three cycles are compared. It is found that ammonia-lithium...
