 Thermal performance of an absorption-refrigeration system with [emim]Cu2Cl5/NH3 as working fluidWei Chen and Yang Bai Energy, 2016, vol. 112, issue C, 332-341 Abstract: The vapor pressures of [emim]Cu2Cl5/NH3 at ammonia mole fractions (x1) ranging from 0.90 to 0.96 at temperatures (T) ranging from 303.15 K to 483.15 K were determined by employing a static method. The correlation of experimental data was calculated by using a modified UNIFAC (Dortmund) model with a total uncertainty of <4.1%. The specific enthalpy of [emim]Cu2Cl5/NH3 binary solution was also calculated on the basis of the predictive excess molar enthalpy of the UNIFAC model. The thermal performance of an absorption refrigeration system with [emim]Cu2Cl5/NH3 as working fluid was simulated. The thermal performance of the [emim]Cu2Cl5/NH3 system is better than those of absorption systems with NH3/H2O, [choline][NTf2]/NH3, [emim][Ac]/NH3, and [emim][EtOSO3]/NH3 as working fluids. The coefficients of performance and exergy efficiency of the [emim]Cu2Cl5/NH3 system are slightly lower than those of the LiBr/H2O system. The evaporating temperature scope of the former is wider than that of the latter. The [emim]Cu2Cl5/NH3 system also possesses several advantages, including non-crystallization and non-corrosion.
