Thermal And Chemical Stability

Ionic liquids are generally non-volatile, non-toxic, and nonflammable with high heat capacity, high density, and high thermal and chemical stability. This paper considers their use as absorbents in an absorption refrigeration cycle. A dynamic model of a single-effect absorption refrigeration cycle using ionic liquids as absorbent is developed. Modeling of the cycle performance requires thermodynamic properties which are obtained from an equation of state for the refrigerant-absorbent mixture (solution). The transient response of the cycle is investigated. Some design and operating parameters that affect the cycle performance are identified.
