Abstract
AbstractThis paper presents the design and performance of a naturally ventilated fog cooled greenhouse coupled with solar still. The greenhouse is East–West oriented, and its microclimate is maintained using evaporative cooling through foggers. The canopy-mounted solar still produces freshwater from brackish or saline water. The analysis is performed on a representative day for the month of May and December for Kolkata located in the state of West Bengal and representing hot and humid climatic conditions. Computer codes are developed in-house to develop thermodynamic model for analysing the performance of the integrated system. The study reveals that the solar still can produce maximum 26.39 kg of fresh water on a typical summer day. It is also found that the greenhouse temperature can be maintained at a level 6 °C below the ambient during peak sunshine hours on a typical summer day.KeywordsGreenhouseSolar stillDesalinationFog coolingNatural ventilation
