Experimental results on a solar desiccantand evaporative cooling systemequipped with wet heat exchangers

An innovative solar assisted desiccant and evaporative cooling (DEC) system forbuilding air conditioning has been installed at the Solar Laboratory of the University ofPalermo. In this system, air-to-air packaged wet heat exchangers are used tomaximise the exploitation of the evaporative cooling potential associated with theexhaust air stream.Results obtained are very positive, showing that DEC systems can benefit from theuse of wet heat exchangers to efficiently cool the air stream after the adsorptionprocess in the desiccant wheel, without any change in moisture content
