The Performance Research and Orthogonal Analysis of Humidification-dehumidification Technology (HDH) System

Thermodynamic analysis of humidification dehumidification

Humidification dehumidification desalination (HDH) is a promising technology for small-scale water production applications. There are several embodiments of this technology which have been investigated by researchers around the world. However, from a previous literature review [1], we have found no study which carried out a detailed thermodynamic analysis in order to improve and/or optimize the...

Variable Pressure Humidification Dehumidification Desalination System

Nature uses air as a carrier gas to desalinate seawater through evaporation and rain. Several investigators have previously studied desalination cycles based on carrier gas processes. However, single pressure carrier gas cycles suffer from low energy recovery and hence low performance. Here we discuss a novel carrier gas cycle which operates under varied pressure. This cycle operates the evapor...

Experimental Validation for Two Stages Humidification- Dehumidification (hdh) Water Desalination Unit

This paper demonstrates the preliminary experiments for two stage water desalination by humidification-dehumidification HDH process. An experimental set-up consists of two stages of closed air humidification dehumidification units. In this design, the saline water was heated by evacuated tube solar water heater integrated with electrically heated tank. A series of tests were performed in outdoo...
