“…These data are in reasonable agreement with literature values, although they are difficult to compare owing to differences in temperature, concentration, impurities, or method. For instance, the water vapor pressure of LiCl has been reported by Johnson et al with 16.1 mbar at a concentration of 45.8 wt % (30 °C) using an indirect calorimetric method . All investigated ILs obtained a reduced or comparable water vapor pressure referring to LiCl as a benchmark.…”

Aqueous solutions of lithium halides are state-of-the-art sorbents in sorption-based heat pump and heat storage devices, with the drawbacks of high corrosivity and limited natural resources of lithium. Halide-free ILs could be well-suited alternative sorbents and have been explored with isothermal titration calorimetry showing superior thermochemical performance. Here, we have explored the performance of selected halide-free ILs in perfusion measurements monitoring the uptake of water vapor and CO2 from an air stream with well-defined flow and humidity as a model for open sorption processes. We have determined the saturation vapor pressure of water in the corresponding water–IL mixtures and moreover determined the diffusion coefficients of molecular species in binary [EMIM][Ac]–water mixtures via pulsed-field-gradient nuclear magnetic resonance (PFG NMR) measurements. These, together with variation of the absorption rates with calorimetric monitoring, indicate that diffusion is approximately 3 orders of magnitude faster than absorption and that the fast absorption process is not diffusion limited for [EMIM][Ac] in the used concentration range (D = 5.046 ± 0.021 × 10–11 m2/s; T = 25 °C). All measurements have been carried out in comparison to LiCl which corroborates the superior performance with regard to reducing water vapor pressure, heat of dilution, and absorption rate of acetate-based ILs and [EMIM][Ac], in particular.

Abstract-The solar potential energy in Tunisia can be used like a principal factor for the operation of new technologies of air conditioning. Studies could be carried out like approaches of simulation, analyzes experimental or both unit. In this paper, we present an analytical solution of heat and mass transfer processes in regenerator and air conditioning system (ACS) cores of a heat recovery /desiccant cooling system (HRDCS) under Tunisia weather conditions. Simulations programs were carried out to test the principal components of the HRDC system. The results show that the coefficient of performance of system improves when we use the renewable energy for heating and cooling. This study is significant and effective to prove the efficiency of such HRDC systems in this country.
