  Ionic liquids are nonvolatile, non-toxic and non-flammable liquids with high thermal and chemical stability. Therefore they are suggested as a solvent in absorption refrigeration cycle. For modeling of cycle operating should be specified thermodynamics properties. One thermodynamics model is used for one effect absorption refrigeration cycle. Thermodynamics properties of refrigerant-solvent mixture are modeled by equation of state. [hmim][Tf2N], [emim][Tf2N] and [hmim][BF4] are used as solvents and R134a is used as a refrigerant. Results compare with other common refrigerant-solvents. Coefficient of performance of these systems are lower than common cycle like LiBr-water and water-NH3 but specific properties of ionic liquids such as nonvolatile, non corrosive, non-flammable and eco-friendly, cause very research perform to get proper refrigerant and ionic liquid as a solvent Manuscript profile
