Highly efficient absorption heat pump and refrigeration systems based on ionic liquids: Fundamentals & Applications

Improving efficiencies of thermal energy conversion systems is an important way to slow down global warming and mitigate climate change. Vapor absorption heat pump and refrigeration cycles are highly efficient ways of heating and cooling. These thermally activated systems also provide opportunities for the integration with a wide spectrum of low...

Molecular simulation of NH₃/ionic liquid mixtures for absorption heat pump cycles

Force Field based Monte Carlo (MC) simulations are conducted to predict the performance of an absorption heat pump cycle involving NH3/ionic liquid (IL) (refrigerant/absorbent) as working pair. To investigate the thermodynamic performance of the cycle, various properties such as the enthalpy of absorption, heat capacity, and solubility of...

Absorption heat pump cycles with NH₃ – ionic liquid working pairs

Ionic liquids (ILs), as novel absorbents, draw considerable attention for their potential roles in replacing water or LiBr aqueous solutions in conventional NH₃/H₂O or H₂O/LiBr absorption refrigeration or heat pump cycles. In this paper, performances of 9 currently investigated NH₃/ILs pairs are...
