Abstract
Coastal area where clean drinking water availability is measured problem, which insist to innovate cheep, decentralized small-scale water production.The geographical conditions of vadodara (22.00N, 72.10E ),and kachh,Gujarat are best suitable for humidification-dehumidification (HDH) technique based on closed-water, open-air cycle where air heated system is used. There are different types of heat exchangers available as dehumidifiers for HDH applications vary but they have required strength to withstand corrosive nature of seawater, there for frames, collecting plates, fins are made of aluminum. In addition, special attention was exercised to avoid leakage of distillate water. Dehumidifiers is heat exchanger in which heat exchange is takes places between two fluids i.e. hot and cold that are at different temperatures. The heat exchange in the heat exchanger may be in the form of latent heat or sensible heat or combination of both. The HDH concept are also reviewed and compared. Further, novel proposals for improvement of the HDH cycle are outlined. It is notice that HDH technology has great promise to produced fresh water using circular solar collector, although additional research and development is needed for improving system efficiency and reducing capital cost.
