Abstract

The work evaluates experimentally technique toimprove fresh water production by careful energy recovery inthe vapour condensation processes; the recovered heat in turnon drives additional evaporation and preheats the feedwater. Apilot plant is designed and constructed in an arid area with 2 m2solar evaporation collector area to evaluate the process. Thisunit is tested on cold and hot days. The effect of mainparameters on fresh water production of the unit is studied. Theexperimental results show that, the production rate andefficiency of the system are strongly affected by solar radiationand level water in solar evaporation collector. Within the studiedranges, the maximum productivity reached to 16.1 kg/ m2day atTvap,av = 87.6 oC , solar radiation 842 W/m2 and level water 1.912kg. According to these results, fresher water production of thepresent system is higher than that solar still desalination systemin the previous studies.
