Experimental performance analysis and simulation of an internally cooled liquid desiccant air conditioning system using a novel ionic liquid

摘要

The search for new and more energy-efficient solutions with natural fluids has become a clearcountermeasure for mitigating the carbon footprint of air conditioning and refrigerating systems. In theabsorption field, specifically in liquid desiccant air conditioning systems, the application of internal coolingin gas-liquid contactors is limited due to the corrosion property of commonly used liquid desiccants.Internally cooled/heated liquid desiccant systems have better heat and mass transfer performance comparedto adiabatic systems but mathematical modeling becomes more complicated.In this study, experiments and simulations were carried out to evaluate the performance of an internallycooled/heated liquid desiccant air conditioning system using a novel ionic liquid. This innovative solutionbecame possible due to the compatibility, in terms of corrosion, of the newly developed ionic liquid withaluminum. The validated mathematical model can be used to conduct parametric and optimization studies forthe internally cooled/heated liquid desiccant air conditioning system.
