Experimental and Theoretical Model for Water Desalination by Humidification - dehumidification (HDH)

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...

Experimental Study of Humidification-Dehumidification (HDH) Seawater Desalination Driven by Solar Energy

Experimental study for hybrid humidification–dehumidification water desalination and air conditioning system

• A new hybrid humidification–dehumidification and air conditioning system is proposed and investigated. • The proposed system keeps the function of the air conditioning system and uses it in water desalination. • The effects of system operating parameters on system performance were evaluated and correlated. a b s t r a c t a r t i c l e i n f o An experimental study of the performance of a hyb...

Thermodynamic Analysis of Humidification Dehumidification Desalination Cycles

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...
