Abstract: A direct-contact, spray-assisted, evaporation and condensation, DCSEC system includes a heating block configured to receive and heat up seawater; plural evaporation and condensation stages, wherein n is a natural number, each stage being configured to generate water vapors through flash evaporation; an evaporation only stage connected to a last stage of the plural evaporation and condensation stages, the evaporation only stage configured to receive a brine from the last stage n of the plural evaporation and condensation stages; an input/output block configured to receive the brine from the evaporation only stage and to discharge it outside the system, and also to receive cooling water; and a pressure-swing regeneration block fluidly connected to the evaporation only stage to receive the water vapors and to generate a hot vapor, which is provided to the heating block for heating the seawater.

Abstract: A hybrid air conditioning system for cooling a chamber, the hybrid system including a desiccant-coated heat pump configured to cool, through evaporation and condensation of a refrigerant, a first air stream OA, and an indirect evaporative cooling, IEC, unit configured to cool a second air stream MA, which is related to the first air stream OA, through direct heat exchange between wet channels that are placed adjacent to dry channels. The desiccant-coated heat pump is fluidly connected to the IEC unit so that a generated supply air stream SA is dehumidified by a desiccant material coated on first and second heat exchangers of the desiccant-coated heat pump.

Abstract: A hybrid air conditioning system for cooling a chamber includes a mechanical vapor compression, MVC, unit configured to cool, through evaporation and condensation of a medium, a first air stream (MA1, MA, MA2); and an indirect evaporative cooling, IEC, unit configured to cool a second air stream (CA, MA2, OA), which is related to the first air stream (MA1, MA, MA2), through direct heat exchange between wet channels that are placed adjacent to dry channels. The MVC unit is fluidly connected to the IEC unit so that a generated supply air stream SA is cooled by decoupling sensible and latent heat removal.
