Abstract
Abstract The present paper deals with the experimental study of the liquid desiccant air conditioning system using the single storage solution tank. The novelty of the system is that the dehumidification and regeneration are carried out in a single compact unit. The regeneration of solution is done using the marquise-shaped solar collector. The liquid desiccant solution used here is calcium chloride and water. The moisture removal rate (MRR), moisture, and enthalpy effectiveness are used as the performance parameters. The effects of mass flowrate of solution, solution temperature, inlet air temperature, and relative humidity (RH) on the performance are investigated. The experimental outcome shows that when the solution flowrate is increased from 0.263 to 0.437 kg/s, the MRR is improved from 5.08 to 7.82 g/kg and when the RH is increased from 70% to 92%, the MRR is enhanced from 5.56 to 12.45 g/kg. The new correlation for moisture effectiveness is developed based on the experimental values and depending parameters, and also another correlation is developed based on Chung’s correlation (Chung, T.-W., 1994, “Predictions of Moisture Removal Efficiencies for Packed-Bed Dehumidification Systems,” Gas Sep. Purif., 8(4), pp. 265–268).
