Abstract
The application of ionic liquid in the ammonia absorption system is current research hotspot. The low solubilities of ammonia in common ionic liquids lead to poor thermal performances of absorption systems, which is the main obstacle faced by ionic liquid absorption systems. Hence, we proposed a new idea of using ionic liquids containing metal cations to enhance the thermal performances of the absorption systems. The specific ionic liquid being studied is [Na(TX-7)]SCN. The vapor–liquid equilibrium and heat capacities of [Na(TX-7)]SCN/NH3 were studied by experimental methods. Based on above physical properties, the thermal performances of absorption refrigeration and absorption heat transformer using [Na(TX-7)]SCN/NH3 were simulated and compared with those of other systems. The thermal performances of [Na(TX-7)]SCN/NH3 absorption refrigeration are better than NH3/H2O system and other ionic liquid systems, but is a bit lower than NaSCN/NH3 system. The thermal performances of [Na(TX-7)]SCN/NH3 absorption heat transformer are better than those of the [mmim]DMP/H2O and [mmim]DMP/CH3OH systems, similar to those of the NaSCN/NH3 system, and slightly lower than those of the LiBr/H2O system. Overall, the proposed working fluid obviously improves the thermal performances of ionic liquid system and solves the crystallization problem of NaSCN/NH3 and LiBr/H2O systems.
