HIGHLIGHTS

  • Thermoelectric cooling leads to increase in yield of solar still (SS).
  • The evaporative and convective heat transfer coefficients are two key parameters to design a SS.
  • The yield is affected by the depth of water in SS.
  • There is a proportional relationship between the yield and solar radiation.
  • For a fixed length of SS, the yield increases with decrease of specific height.

ABSTRACT

Drinking water scarcity is a critical problem around the world in the 21st century. Population expansion, global climate change, urbanization, vegetation destruction and deforestation are causes for this crisis. Beside this, it is worth mentioning that only 0.014% of water in earth can be applied directly for the human consumption. This storage reveals the impact of desalination process and similar industrial. All desalination techniques require fossil fuel or electrical energy. A simple type of desalination device is solar still with many advantages such as simplicity, endless amounts of energy (free of charge), ability to supply fresh water to remote areas where no fresh water is available, cost savings, reduced consumption of fossil fuels and many other benefits. These advantages make this device attractive. Researchers try to improve the performance of this device by various techniques. This paper is a brief review on recent attempts to improve the performance of solar stills.
