Umidification Dehumidification Cycle News Today : Breaking News, Live Updates & Top Stories | Vimarsana

Saline water desalination is attaining a prime focus to meet the challenges of water scarcity in the developing countries. Solar energy could be effectively utilized for desalinating the saline/sea water. In this respect, humidification dehumidification (HDH) cycle could prove as a promising solar driven desalination technology. In this paper, exergy analysis of single extraction air heated and water heated HDH desalination cycles are examined in detail. The top temperature and extraction rate parameters are considered crucial for any typical single extraction HDH cycle. Analysis of the effects of varying top cyclic temperature keeping fixed extraction/injection rate of 70% water/air stream is carried out. The top temperature is varied between 60 °C−80 °C range. For the air heated air extraction cycle, total exergy destroyed is higher at lower top temperatures, resulting in lower exergetic efficiency. A similar trend is also followed by the air heated water extraction cycle for the ....
