• Resumen

  • The present thesis is undertaken to study the use of an aqueous solution of LiCl as a secondary refrigerant, due to its dehydrating properties, in those refrigeration applications that require mainly the air dehumidification and where the conventional methods show technical difficulties and/or a high energetic cost. The study of mass and heat transference between the aqueous solution of LiCl and the air is made, and it is applied to different conditions of dry temperature and air relative humidity. Regeneration of the aqueous solution of LiCl is solved using the condenser thermal power from the same refrigeration circuit, removing the dependence on other external heat sources, thus increasing the installation energetic efficiency. The analysis of the obtained results and the energetic comparative regarding to the conventional methods used so far show this is really an alternative to consider.
