Experimental results on a solar desiccantudand evaporative cooling systemudequipped with wet heat exchangers

摘要

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