SIMULATION AND ECONOMIC ASSESSMENT OF SOLAR DESALINATION BY AIR HUMIDIFACTION-DEHUMIDIFACTION

Abstract

This study mainly depends on solar desalination by humidification dehumidification method, this work divided into two parts: theoretical study and simulation study. Theoretical study depends on papers that already published in journals, and also climate of Egypt in both summer and winter case, the aim of studying climate is to know both suitable solar radiation and rate of evaporation and condensation, while simulation study depends on data from published paper, after doing mass and heat balance from simulation program, the parameters used are ratio between air to saline water, air temperature, recovery ratio, and specific energy consumption. Simple design of equipment is calculated, in order to know cost of fresh water, the maximum capacity of fresh water is 347 m3/hr with cost 1.14 $/m3.
